Nested THREADS!!!
hi frens,
i have made a thread say T1 for a class A which extends another class B. class B also has a thread T2. my problem is when i sleep thread T1, thread T2 is still running. but i want both of them to sleep. thread T2 is private so i cant access it from class A. how can i get my job done. pls help me. thanks alot....
actually i am writing a program for downloading.i have made a class with extends the package class which does the downloading purpose. it uses a thread for downloading. now i want to access that thread from my class. my problem is that thread is declared private which means i cant access it from my class and second i dont have the java file for that package class, so i cant even modify the super class. so it there anyway so that i can control the thread of my super class from my class. i hope i made that clear. any sort of helps are welcomed. thank you for ur attention.

Duplicando registro tabela NAST após chamada J_1BNFE_CALL_RSNAST00
Boa tarde pessoal,
estava conversando com o Fernando nesta [Thread|; e resolvi abrir uma nova thread.
Estava implementando a badi de impressão do danfe e notei um comportamento estranho.
Após gerar uma NFe, é gerado um registro na NAST.
Na sequencia, executo o FM J_1B_NFE_XML_IN para simular o aceite desta NFe, o que acarreta na chamada da badi de impressão e na minha badi tenho a chamada p/ o FM J_1BNFE_CALL_RSNAST00.
Dentro deste FM, ele move alguns parâmetros de entrada para a NAST e chama o form einzelnachricht, que chama tnaprlesen_, optischearchivierung_, programmaufrufen_, protocolstore_ e finalmente o nastupdate_.
Neste ponto do programa, a chave que tenho no header da tabela NAST é diferente da que já consta na tabela do bd.
No BD tenho este registro na NAST:
MANDT 321
KAPPL NF
OBJKY 0003347752
KSCHL ZNFE
SPRAS E
PARNR
PARVW
ERDAT 06/24/2009
ERUHR 14:38:41
e no programa, no form nastupdate_, tenho o header da NAST assim:
MANDT
KAPPL NF
OBJKY 0003347752
KSCHL ZNFE
SPRAS
PARNR
PARVW
ERDAT 00000000
ERUHR 000000
Sendo assim, quando ele dá o update nast. ele dá sy-subrc = 4, e na sequencia, o código trata if sy-subrc ne 0, insert nast. Com isso tenho 2 registros na NAST pra mesma NF, um com o status VSTAT = 1, mas com o SPRAS/ERDAT/ERUHR não preenchidos e o outro, o "original", com tudo preenchido porém com o status VSTAT = 0.
Olhando o Spool na SP01 eu vejo a NFe "impressa" apenas uma vez, o que está correto. Mas o que me incomoda é que ele acaba gerando registros duplicados.
Segue meu código da BADI:
IF i_active-code EQ '100' "NF-e autorizada
AND i_active-printd IS INITIAL "só imprimir automaticamente se ainda não foi impressa
AND i_active-cancel IS INITIAL "não faz sentido imprimir autom. se ela foi cancelada
AND i_active-conting_s IS INITIAL. "não faz sentido imprimir autom. se ela foi alternada
"p/conting. pois deverá ser cancelada
CALL FUNCTION 'J_1BNFE_CALL_RSNAST00'
EXPORTING
I_ACTIVE = i_active
I_DIMME = 'X'
I_PRINTER = vl_printer
EXCEPTIONS
no_printer = 1
others = 2.
COMMIT WORK.
IF sy-subrc = 0.
CALL FUNCTION 'J_1B_NFE_ERROR_PROTOKOLL'
EXPORTING
i_docnum = i_active-docnum.
ENDIF.
ENDIF.
Para "resolver" esse pequeno problema (ao meu ver, não sei se está correto ou não este comportamento), criei um FM Z com o seguinte código:
FUNCTION ZBR_J_1BNFE_CALL_RSNAST00.
""Local Interface:
*" IMPORTING
*" VALUE(I_ACTIVE) TYPE J_1BNFE_ACTIVE
*" VALUE(I_KAPPL) TYPE NAST-KAPPL DEFAULT 'NF'
*" VALUE(I_NACHA) TYPE NAST-NACHA DEFAULT '1'
*" VALUE(I_DIMME) TYPE NAST-DIMME DEFAULT 'X'
*" VALUE(I_PRINTER) TYPE RSPONAME OPTIONAL
*" EXCEPTIONS
*" PRINT_ERROR
TABLES: nast.
SELECT SINGLE *
FROM nast
WHERE kappl = i_kappl AND
objky = i_active-docnum AND
kschl = i_active-form AND
nacha = i_nacha AND
vstat = '0'.
start printing
nast-kappl = i_kappl.
nast-objky = i_active-docnum.
nast-kschl = i_active-form.
nast-nacha = i_nacha. "1 = print output
"nast-ldest = i_printer.
"nast-dimme = i_dimme. "X = print immidiately
PERFORM einzelnachricht IN PROGRAM rsnast00 USING sy-subrc.
IF NOT sy-subrc IS INITIAL.
MESSAGE i230(8b) with i_active-docnum RAISING print_error. "#EC *
ENDIF.
ENDFUNCTION.
e na BADI, o chamei desta forma:
CALL FUNCTION 'ZBR_J_1BNFE_CALL_RSNAST00'
IN BACKGROUND TASK
EXPORTING
i_active = i_active
EXCEPTIONS
no_printer = 1
others = 2.
Desta maneira, não ocorreu a duplicação dos registros da NAST e a nota também foi impressa OK.
A minha dúvida é se realmente o comportamento esperado utilizando o primeiro procedimento é duplicar o registro na NAST ou se pode ser que tenha algo errado no meu sistema(SAP_APPL 602 SP01) na hora da chamada da RSNAST00.parte 1

Pessoal,
estou com o seguinte problema: tenho a nota de número 91820 que se encontra cancelada na Sefaz e no ECC.
Entretanto, a equipe de Basis descobriu qua a nota está sofrendo tentativas de update no ECC.
Verifiquei que não existe nenhum processo sendo executado no GRC e no PI que esteja acionando o update do ECC.
Na SM13, do ECC, o erro está descrito como:
Report: SAPLJ_1B_NFE
Functional Module: J_1B_NFE_UPDATE_INVALID
Status: Update was terminated
Report: LJ_1B_NFEU13
Row: 149
Class: J1B_NFE
Number: 060
Error Details: J1B_NFE 060 DB error insert of record with key 0000091820
Como resolver esse problema?
Abs,
SérgioBom dia Sérgio,
Verifique na tabela /XNFE/BACKSTATUS no GRC, se você diz que está tudo ok nos sistemas então ela foi parar aí por um erro de comunicação entre o GRC e o ERP.
Quem está "insistindo" na transmissão é o programa /XNFE/UPDATE_ERP_STATUS que roda escalonado no GRC para retransmissão ao ERP.
Sugestão:
- Verifique cada linha na tabela /XNFE/BACKSTATUS, pois após rodar o job acima ela deve ficar vazia.
- Se tem vários registros nela, pode matar com SE14 de uma vez (faça backup dos dados no Excel, mas não tenha medo pois você pode reenviar o resultado para o R/3 rodando este mesmo programa informando a chave de acesso, na versão nova isto se faz com o /XNFE/UPDATE_ERP_STATUS_DIAL)
- No R/3 monitore esta tabela J_1B_NFE_UPDATE_INVALID, ela é o log de tudo que o R/3 recusou em processar

Communication between multiple processes
Hi there!
I have once again a problem concerning paralel processing in ABAP.
The problem is that:
I want to write a programm which invokes a process that can recursive invoke another process and so on.
Let me try to picture it out:
-> means invokes
Main Program -> Thread1
Thread 1 -> Thread 2
Thread 2 -> Thread 3
Thread 2 -> Thread 4
Thread 4 -> Thread 5
Thread 5 -> Thread 6
As you can see I have several Threads invoking another Thread. The structure of Threads invoking each other will be dynamic. Now I face the following problem:
I want just a few threads to run at the same time (let's say for now 3) and there are dependencies between the Invoker and the invoked Thread (e.g. Thread 3 needs some information from Thread 2).
How can I let my Main Program know that all the data is ready? Does the WAIT UNTIL statement also applies for these nested threads?
How does Thread 5 e.g. know that there are already too much processes running and he has to wait?
Is there a possibility how I can queue these processes?
sth like:
Thread 1 - Thread 2 - Thread 3 - Thread 4 - Thread 5 - Thread 6
If prerequisites for Thread 3 are not fullfilled it would look like:
Thread 1 - Thread 2 - Thread 4 - Thread 5 - Thread 6
and so on...
The problem is the communication over the bounds of Threads. This dynamic structure is neccessary due to the large data amount that I have to handle. Due to restrictions I can only use a function group and a report. No database tables or stuff like that is allowed.
I hope I was able to point out my problem. If it was to unclear please let me know it, then I will try to specify it more.
Thank you in advance for your help.
Best Regards,
Sebastian@ Sandeep: Thanks for your answer I am going to have a look at that
@ Thomas: These nested Calls would be useful because of the amount of data that has to be processed. Think about a Tree with over 200.000 entries. For each entry there is the requirement for Check if corresponding dataset is right, if necessary Adapt data and Update on the database.
The approach with the nested threads would check a single node, looks whether there are child nodes and if so starts a thread for processing the child nodes. These would check each child node and if neccessary starts another thread and so on. Child nodes can only be changed if parent change was successful so I have the dependency right here.
Yesterday I had another idea that should work:
My Main Programm first checks the root node and then the direct childs of the root node (1st hierarchy level). Then invokes a thread for each child node which has again child nodes and for which changes applied (2nd hierarchy level. Each thread 'returns' a list of nodes for which once again the main program should invoke another thread and so on. (This would build up a queue for processing within the Main Program)
It is a similar approach to the think with nested threads but the control structure is more clear and there is no nesting of threads neccessary.
Thanks and Best Regards,

PL/SQL add procedure with nested table - Duplicate Thread
Hi,
I am trying to do a procedure to input information for one order and another for 2 orders.
The information I have so far is as follows:
Drop table Orders cascade constraints;
Drop type item_type;
Drop type Item_nested;
Create or Replace Type item_type AS Object (
Cat_code Varchar2(6),
Amount_ord Number(3),
Cost Number(5,2) );
Create or Replace Type item_nested as table of item_type;
Create Table Orders (
Order_no Varchar2(8) constraint pkorder primary key,
Customer_name Varchar2(30),
AddressLine1 Varchar2(20),
AddressLine2 Varchar2(20),
AddressLine3 Varchar2(20),
Town Varchar2(20),
Postcode Varchar2(10),
Country Varchar2(20),
Order_items item_nested,
Order_date Date)
Nested Table Order_items
Store as nested_items return as locator;
This has so far worked but I have not managed the insert procedure.
I am using Oracle SQL*plus
Thanks

Are static nested classes thread-safe?
There doesn't seem to be any definitive answer to this. Given the following code, is it thread-safe?
public class SomeMultiThreadedWebController {
public HttpServletResponse someMethodToExecuteViaWebRequest(HttpServletRequest request) {
simpleQueryBuilder("SELECT...").addParameter("asdf","asdf").createQuery(EMF.getEntityManager()).executeUpdate();
protected static class SimpleQueryBuilder {
private String queryString;
private Map<String, Object> params = new HashMap<String, Object>();
public SimpleQueryBuilder(String queryString) {
this.queryString = queryString;
public SimpleQueryBuilder addParameter(String name, Object value) {
params.put(name, value);
return this;
public Query createQuery(EntityManager em) {
Query query = em.createQuery(queryString);
for (Entry<String, Object> entry : params.entrySet()) {
query.setParameter(entry.getKey(), entry.getValue());
return query;
public static SimpleQueryBuilder simpleQueryBuilder(String queryString) {
return new SimpleQueryBuilder(queryString);
}Forget whether or not someone would do this, as this is just an example. I'm really trying to get at whether or not the instance variables inside the static nested class are thread-safe. Thanks for any responses.Hello,
I believe you understand what you're talking about, but you state it in a way that is very confusing for others.
Let me correct this (essentially, incorrect uses of the terminology):
I agree that thread-safe or not is for an operation, for a member, it has some sort of contextual confusion.
Member has a much broader meaning in the [Java Language Specification|http://java.sun.com/docs/books/jls/third_edition/html/names.html#6.4] . Even "class member" applies to both an attribute, a method, or an inner class or interface.
I think you mean "member variable" of a class (aka "attribute" or "field"). By the way, static or not is irrelevant to the rest of the discussion.
For an operation or a member, if there's only one thread could access it atomically in one moment, we could call it thread-safe.Mmm. I was tempted to say yes (I'm reluctant to commit myself). With an emphasis on "_The encapsulating class_ makes this member's usage thread-safe".
Still, just synchronizing each operation on a member is not enough to make all usages "thread-safe":
Consider a java.util.Vector: each add/get is synchronized, so it is atomic, fine.
However if one thread adds several values, let's say 3, one by one, to a vector that initially contains 0 values, and another thread reads the vector's size() (another properly synchronized method), the reader thread may witness a size anywhere among 0, 1, 2, 3, which, depending on the business logic, may be a severely inconsistent state.
The client code would have to make extra work (e.g. synchronizing on the vector's reference before the 3 adds) to guarantee that the usage is thread-safe.
Thus any synchronized method(With the limit stated above)
or immutable member (like primitive type) are thread-safe.
Additionally for a member, if it's immutable, then it's thread-safe. You mean, immutable primitive type, or immutable object. As stated previously, an immutable reference to a mutable object isn't thread-safe.
a static final HashMap still have thread-safe issue in practice because it's not a primitive.The underlined part is incorrect. A primitive may have thread-safety issues (unless it's immutable), and an object may not have such issues, depending on a number of factors.
The put, get methods, which will be invoked probably, are not thread-safe although the reference to map is.Yes. And even if the put/get methods were synchronized, the client code could see consistency issues in a concurrent scenario, as demonstrated above.
Additional considerations:
1) read/write of primitive types are not necessarily atomic: section [ §17.7 of the JLS|http://java.sun.com/docs/books/jls/third_edition/html/memory.html#17.7] explicitly states that writing a long or double value (2 32-bits words) may not be atomic, and may be subject to consistency issues in a concurrent scenario.
2) The Java Memory Model explicitly allows non-synchronized operations on non-volatile fields to be implemented in a "thread-unsafe" way by the JVM. Leading way to a lot of unintuitive problems such as the "Double-Checked Locking idiom is broken". Don't make clever guess on code execution path unless you properly synchronize access to variables across threads.

consider this:
Thread thread1 = new Thread(new Runnable(){
Thread2.start();
}).start();
thread1.sleep(100000);Will thread 2 continue unimpeded?
I would have assumed it would, as its kinda the point of threads as i understood them, but im having some unexpected behaviour, and clarification on this point will aid me with debugging.
Thank youJamesBarnes wrote:
Ahh i see, that makes sense.
OK, with that in mind, i want a thread to perform a check every now and then (generally ~5minutes), would it be be bad practice to do the following?
new Thread(new Runnable(){
private void run(){
while(true){
if( timeElapsedSinceLastCheck > interval ){
perform check and respond
}).start();
If you don't put a sleep() inside that loop, then, yes, very bad idea. -

Follow up on an old thread about memory utilization
This thread was active a few months ago, unfortunately its taken me until now
for me to have enough spare time to craft a response.
From: SMTP%"[email protected]" 3-SEP-1996 16:52:00.72

Subj: Re: memory utilization
As a general rule, I would agree that memory utilzation problems tend to be
developer-induced. I believe that is generally true for most development
environments. However, this developer was having a little trouble finding
out how NOT to induce them. After scouring the documentation for any
references to object destructors, or clearing memory, or garbage collection,
or freeing objects, or anything else we could think of, all we found was how
to clear the rows from an Array object. We did find some reference to
setting the object to NIL, but no indication that this was necessary for the
memory to be freed.
I believe the documentation, and probably some Tech-Notes, address the issue of
freeing memory.
Automatic memory management frees a memory object when no references to the
memory
object exist. Since references are the reason that a memory object lives,
removing
the references is the only way that memory objects can be freed. This is why the
manuals and Tech-Notes talk about setting references to NIL (I.E. freeing memory
in an automatic system is done by NILing references and not by calling freeing
routines.) This is not an absolute requirement (as you have probably noticed
that
most things are freed even without setting references to NIL) but it accelerates
the freeing of 'dead' objects and reduces the memory utilization because it
tends
to carry around less 'dead' objects.
It is my understanding that in this environment, the development tool
(Forte') claims to handle memory utilization and garbage collection for you.
If that is the case, then it is my opinion that it shoud be nearly
impossible for the developer to create memory-leakage problems without going
outside the tool and allocating the memory directly. If that is not the
case, then we should have destructor methods available to us so that we can
handle them correctly. I know when I am finished with an object, and I
would have no problem calling a "destroy" or "cleanup" method. In fact, I
would prefer that to just wondering if Forte' will take care of it for me.
It is actually quite easy to create memory leaks. Here are some examples:
Have a heap attribute in a service object. Keep inserting things into
the heap and never take them out (I.E. forgot to take them out). Since
service objects are always live, everything in the heap is also live.
Have an exception handler that catches exceptions and doesn't do
anything
with the error manager stack (I.E. it doesn't call task.ErrMgr.Clear).
If the handler is activated repeatedly in the same task, the stack of
exceptions will grow until you run out of memory or the task terminates
(task termination empties the error manager stack.)
It seems to me that this is a weakness in the tool that should be addressed.
Does anyone else have any opinions on this subject?
Actually, the implementation of the advanced features supported by the Forte
product
results in some complications in areas that can be hard to explain. Memory
management
happens to be one of the areas most effected. A precise explanation to a
non-deterministic process is not possible, but the following attempts to
explain the
source of the non-determinism.
o The ability to call from compiled C++ to interpreted TOOL and back
to compiled C++.
This single ability causes most of the strange effects mentioned in
this thread.
For C++ code the location of all variables local to a method is not
know
(I.E. C++ compilers can't tell you at run-time what is a variable
and what
isn't.) We use the pessimistic assumption that anything that looks
like a
reference to a memory object is a reference to a memory object. For
interpreted
TOOL code the interpreter has exact knowledge of what is a reference
and what
isn't. But the TOOL interpreter is itself a C++ method. This means
that any
any memory objects referenced by the interpreter during the
execution of TOOL
code could be stored in local variables in the interpreter. The TOOL
interpreter
runs until the TOOL code returns or the TOOL code calls into C++.
This means
that many levels of nested TOOL code can be the source of values
assigned to
local variables in the TOOL interpreter.
This is the complicated reason that answers the question: Why doesn't a
variable that is created and only used in a TOOL method that has
returned
get freed? It is likely that the variable is referenced by local
variables
in the TOOL interpreter method. This is also why setting the
variable to NIL
before returning doesn't seem to help. If the variable in question is a
Array than invoke Clear() on the Array seems to help, because even
though the
Array is still live the objects referenced by the Array have less
references.
The other common occurrence of this effect is in a TextData that
contains a
large string. In this case, invoking SetAllocatedSize(0) can be used
to NIL
the reference to the memory object that actually holds the sequence of
characters. Compositions of Arrays and TextData's (I.E. a Array of
TextData's
that all have large TextDatas.) can lead to even more problems.
When the TOOL code is turned into a compiled partition this effect
is not
noticed because the TOOL interpreter doesn't come into play and
things execute
the way most people expect. This is one area that we try to improve
upon, but it is complicated by the 15 different platforms, and thus
C++ compilers,
that we support. Changes that work on some machines behave
differently on other
machines. At this point in time, it occasionally still requires that
a TOOL
programmer actively address problems. Obviously we try to reduce
this need over
time.
o Automatic memory management for C++ with support for multi-processor
threads.
Supporting automatic memory management for C++ is something that is
not a very
common feature. It requires a coding standard that defines what is
acceptable and
what isn't. Additionally, supporting multi-processor threads adds
its own set of
complications. Luckily TOOL users are insulated from this because
the TOOL to C++
code generator knows the coding standard. In the end you are
impacted by the C++
compiler and possibly the differences that occur between different
compilers and/or
different processors (I.E. Intel X86 versus Alpha.) We have seen
applications that
had memory utilization differences of up to 2:1.
There are two primary sources of differences.
The first source is how compilers deal with dead assignments. The
typical TOOL
fragment that is being memory manager friendly might perform the
following:
temp : SomeObject = new;
... // Use someObject
temp = NIL;
return;
When this is translated to C++ it looks very similar in that temp
will be assigned the
value NULL. Most compilers are smart enough to notice that 'temp' is
never used again
because the method is going to return immediately. So they skip
setting 'temp' to NULL.
In this case it should be harmless that the statement was ignored
(see next example for a different variation.) In more
complicated examples that involve loops (especially long
lived event loops) a missed NIL assignment can lead to leaking the
memory object whose
reference didn't get set to NIL (incidentally this is the type of
problem that causes
the TOOL interpreter to leak references.)
The second source is a complicated interaction caused by history of
method invocations.
Consider the following:
Method A() invokes method B() which invokes method C().
Method C() allocates a temporary TextData, invokes
SetAllocatedSize(1000000)
does some more work and then returns.
Method B() returns.
Method A() now invokes method D().
Method D() allocates something that cause the memory manager to look
for memory objects to free.
Now, even though we have returned out of method C() we have starting
invoking
methods. This causes us to use re-use portions of the C++ stack used to
maintain the history of method invocation and space for local variables.
There is some probability that the reference to the 'temporary' TextData
will now be visible to the memory manager because it was not overwritten
by the invocation of D() or anything invoked by method D().
This example answers questions of the form: Why does setting a local
variable to
NIL and returning and then invoking task.Part.Os.RecoverMemory not
cause the
object referenced by the local variable to be freed?
In most cases these effects cause memory utilization to be slightly
higher
than expected (in well behaved cases it's less than 5%.) This is a small
price to pay for the advantages of automatic memory management.
An object-oriented programming style supported by automatic memory
management makes it
easy to extended existing objects or sets of objects by composition.
For example:
Method A() calls method B() to get the next record from the
database. Method B()
is used because we always get records, objects, of a certain
type from
method B() so that we can reuse code.
Method A() enters each row into a hash table so that it can
implement a cache
of the last N records seen.
Method A() returns the record to its caller.
With manual memory management there would have to be some interface
that allows
Method A() and/or the caller of A() to free the record. This
requires
that the programmer have a lot more knowledge about the
various projects
and classes that make up the application. If freeing doesn'
happen you
have a memory leak, if you free something while its still
being used the
results are unpredictable and most often fatal.
With automatic memory management, method A() can 'free' its
reference by removing
the reference from the hash table. The caller can 'free' its
reference by
either setting the reference to NIL or getting another
record and referring
to the new record instead of the old record.
Unfortunately, this convenience and power doesn't come for free. Consider
the following,
which comes from the Forte' run-time system:
A Window-class object is a very complex beast. It is composed of two
primary parts:
the UserWindow object which contains the variables declared by the
user, and the
Window object which contains the object representation of the window
created in
the window workshop. The UserWindow and the Window reference each
other. The Window
references the Menu and each Widget placed on the Window directly. A
compound Window
object, like a Panel, can also have objects place in itself. These
are typically
called the children. Each of the children also has to know the
identity of it's
Mom so they refer to there parent object. It should be reasonably
obvious that
starting from any object that make up the window any other object
can be found.
This means that if the memory manager finds a reference to any
object in the Window
it can also find all other objects in the window. Now if a reference
to any object
in the Window can be found on the program stack, all objects in the
window can
also be found. Since there are so many objects and the work involved
in displaying
a window can be very complicated (I.E. the automatic geometry
management that
layouts the window when it is first opened or resized.) there are
potentially many
different reference that would cause the same problem. This leads to
a higher than
normal probability that a reference exists that can cause the whole
set of Window
objects to not be freed.
We solved this problem in the following fashion:
Added a new Method called RecycleMemory() on UserWindow.
Documented that when a window is not going to be used again
that it is
preferably that RecycleMemory() is invoked instead
of Close().
The RecycleMemory() method basically sets all references
from parent to
child to NIL and sets all references from child to
parent to NIL.
Thus all objects are isolated from other objects
that make up
the window.
Changed a few methods on UserWindow, like Open(), to check
if the caller
is trying to open a recycled window and throw an
exception.
This was feasible because the code to traverse the parent/child
relationship
ready existed and was being used at close time to perform other
bookkeeping
operations on each of the Widgets.
To summarize:
Automatic memory management is less error prone and more productive but
doesn't come totally for free.
There are things that the programmer can do that assists the memory
manager:
o Set object reference to NIL when known to be correct (this
is the
way the memory is deallocated in an automatic system.)
o Use methods like Clear() on Array and SetAllocatedSize()
on TextData to
that allow these objects to set their internal
references to NIL
when known to be correct.
o Use the RecycleMemory() method on windows, especially very
complicated
windows.
o Build similar type of methods into your own objects when
needed.
o If you build highly connected structures that are very
large in the
number of object involved think that how it might be
broken
apart gracefully (it defeats some of the purpose of
automatic
management to go to great lengths to deal with the
problem.)
o Since program stacks are the source of the 'noise'
references, try
and do things with less tasks (this was one of the
reasons that
we implemented event handlers so that a single task
can control
many different windows.)
Even after doing all this its easy to still have a problem.
Internally we have
access to special tools that can help point at the problem so that
it can be
solved. We are attempting to give users UNSUPPORTED access to these
tools for
Release 3. This should allow users to more easily diagnose problems.
It also
tends to enlighten one about how things are structured and/or point out
inconsistencies that are the source of known/unknown bugs.

this is coming when i m accessing this method:

java.util.Enumeration iter = hash.elements();
int idx = 0;
while (iter.hasMoreElements())
BallImpl impl = (BallImpl)iter.nextElement();
locations1[idx++] = new BallProxy(impl);
return locations1;
why this function is running fine when i m calling this from client unlike getAllBallProxies() nevertheless both are returning the same thing:
* @return an enumeration of all Balls as remote references
public Ball[] getAllBalls()
Ball[] locations = new Ball[hash.size()];
java.util.Enumeration iter = hash.elements();
int idx = 0;
while (iter.hasMoreElements())

Please make the effort to express yourself clearly. You've already been told you're not making much sense and you haven't done anything about it.
how can we make serialized?The concept of serializing a Thread makes no sense whatsoever. You don't want to do it. You don't need to do it. You can't do it. It wouldn't work if you could do it.
Somewhere or other you have a class member that is a reference to a Thread. Remove it or make it transient. If you post the code somebody may help you. If you don't, nobody can possibly do that. -
How do I get an actor to wait for its nested actors to stop running before stopping itself?
I'm developing a series of projects that are based on the Actor Framework and my actor dependency hierarchy is starting to get some depth. One of the issues I'm facing now is making sure that each actor will only stop running (and signal this via a Last Ack to a higher-level actor or via a notification to non-AF code that launches it) once all of its nested actors have stopped running.
For instance, say I have a type of actor that handles communication with a microcontroller over USB - a USB Controller Actor. I might want to have an application-specific actor that launches USB Controller Actor to issue commands to the microcontroller. When shutting down, I want this top-level actor to send a Stop Msg to USB Controller Actor and then wait to receive a Last Ack back before sending a notification within a provided notifier to the non-AF application code, which can then finish shutting down completely.
I'm sure that having actors wait for all nested actors to shutdown before shutting down themselves is an extremely common requirement and I'm confident National Instruments have made it possible to handle that in a simple, elegant manner. I'm just struggling to figure out what that is.
The approaches I've experimented with are:
Creating a pseudo "Stop" message for an actor that won't actually stop it running straight away, but instruct it to stop all nested actors, wait for their Last Acks and then shut itself down by sending Stop Msg to itself. This isn't elegant because it means the client will be forced to fire off these pseudo stop messages instead of Stop Msg to certain actors.
Instantiating an internally-used notifier and overriding Stop Core.vi and Handle Last Ack Core.vi. The idea is that within Stop Core.vi, I send Stop Msg to each of the nested actors and then make it wait indefinitely on the internal notifier. Within Handle Last Ack Core.vi, I make it send a notification using this notifier which allows Stop Core.vi to continue and perform deinitialisation for the top-level actor itself. Figures 1 & 2 below show this approach. I wasn't confident that this would work since it assumed that it was possible for Stop Core.vi to execute and then Handle Last Ack Core.vi to concurrently execute some time after. These assumptions didn't hold and it didn't work. It would have been messy even if it had.
Overriding Stop Core.vi, making it send Stop Msg to each nested actor and then waiting for an arbitrarily long period of time (100ms, 200ms, etc.). What if a nested actor takes only 10ms to shut down? What if takes 400ms?
The figures below show how I implemented the second approach. Ignore the broken object wires - they only appear that way in the snippets.

I think that this would be a nice addition. I think how a program stops is just as important as how it starts.
I think everyone who has worked on AF design agrees with this. Indeed, managing "Stop" was *the* thing that lead to the creation of the Actor Framework in the first place. The other issues (deadlock/hang avoidance and resource management) were secondary to just trying to get a clean shutdown.
CaseyLamers1 wrote:
I find the current code a bit lacking.
My concern would be that the mixing of a verified stop and a regular stop could create confusion and lead to people having trouble during editting and testing with the project ending up locked (due to VIs left running which did not shutting down).
Your concern is to some degree why no verified Stop exists in the AF already. We looked at each actor as an independent entity, and left it open to the programmer to add an additional managment layer for those applications that needed it. But over time, I have seen that particular management layer come up more often, which is why I am exploring the option."
So that gives one of the reasons why this hasn't already been implemented but also points out that it's something quite a lot of people want.

Nested MSO, slideshow inside MSO triggered by button, invisible on start, able to open/close
Consider the following scenario:
(albeit, this may not even be the right way to do this, or perhaps such functionality is not possible based on existing tools at this time, however, I thought I would post and see if anyone has a trick to share...)
I have a slideshow on the page, it is set to auto play.
I would like to hide it initially, and have it trigger with a button... and then let the user close it. Much like the "light box" effects we have all come to know from the web.
Seems easy enough.
However, in my first attempt to do this I did the following:
1- create an OPEN button (F1)
2- create a container box and a CLOSE button, grpup them (F2)
3- turn them both into an MSO (M1)
4- set the button in F1 to trigger F2 (open state)
5- set the button in F2 to trigger F1 (close state)
-> test, works.
next step, slideshow!
I grab 5 images, create a new MSO (M2).
Turn it into a slideshow Folio Overlay...
-> test, works.
Now this is where it gets funky...
MY FAIL 1- If I try to take M2 and then right click M1, there is NO paste into option.
MY FAIL 2- If I click on the Object States Panel, and then Right click State 2 for M1, there is no "past into option"
MY FAIL 3- If I try to "Alt+Ctrl+V" with M2 into State 2 for M1 it does not work.
--> nor does any other scenario where I attempt to paste any MSO into another MSO
I have even tried
x- grouping the MSO slideshow with a non MSO element such as a frame, text boxt, image, ect..
x- taking the 5 images and pasting them into the MSO seperate, and then trying to turn them into a new MSO inside State 2, which the new MSO button is greyed out and will not let me apply it.
Possible solution I have come up with after looking over alot of Bob's stuff in the tutorials area
(PS his videos and tut's realy help, its a differant kind of thinking going on here with DPS, I imagine it relates to how the C in the binary works and is translated by the InDesign GUI into app code... would be nice to just type in "function on_tap(){open_slideshow(vars);}" lol silly programmer, this is primarily a tool for designers ... but I do think its awesomeness, as a programmer, I dont even want to write code anymore after using DPS and Phone Gap...),
so... here it is, not necessarily the most attractive...
1- Make the slide show MSO, push to BACK, set to auto play and swipe allowed...
2- place a large opaque box on top of the slideshow, group it with the OPEN button
3- create a close button
4- turn them into an MSO, now there is an 'open' button in state 1 on top of an opaque box that sends to state 2, and a 'close' button in state 2 that sends to state 1
This seems to work, I have not tested it on all devices, the iPad will kind of do this wierd glitchy thing, as if it "knows" there is something moving underneath the opaque box. Depending on how I have positioned scrollable frames on top of these elements from a stacking perspective there can be some unexpected behavior. The best results I have had from more complex layouts is to get creative with positioning...
any other suggestions, tips, tricks, would be appreciated
ON a site note:
POSSIBLE BUG:
ANYTIME I try to take ANYTHING that is already using the FOLIO OVERLAY and right click the STATE in the STATES PANEL
In Design total crash!!! The only time I can take a FOLIO OVERLAY (FO) and "right click paste into" an MSO state is by clicking on the state on the stage, it can not be done from the panel, the panel only works with non "FO" items... Even though the state in the panel shows the "past into" option, if I do, *poof* instant app crash... FYI for anyone toying with this. Kudo's to Adobe for the outstanding "auto save" feature. It has saved me time, and there for in some strange way, has also saved some of my life.
Here is what InDesign poops out when a "Folio object" is attempted to be "pasted into" an MSO via the MSO panel.

However we could build such a construct by using ExtendScript (Adobe's flavor of JavaScript).
The problem with that is, that Buttons inside a nested MSO will not work as expected. At least my testing is showing that.
If you want nested MSOs without Buttons (inside the nested one) or if you like to experiment, see the following thread:
