Idle definition
I want to know the definition of idle as understand by the portal. If we use a netlet, is the user defined as idle by the portal since we are using a VPN connectivity, between the desktop and the back-end we try to reach.
Up until SP3+HP2, netlet traffic did not reset the idle time. From that version on traffic directed through the Netlet reset the idle time, but for some customers that caused problems if the traffic involved a back-end system sending keep alive packets to the Netlet. Now (not sure from which version) there is an option to specify whether or not client-bound Netlet traffic resets the session idle time or not.

About return type and parameter type in IDL
I don't know how to define return type and parameter type in
operations in a module which are not listed in predefined in
IDL. can I define these types as java class?
can someone help me where a tutorial about this in detail can
be found?
thanks a lotMy understanding is that if something is not in the IDL definition, then as far as the CORBA system is concerned it doesn't exist.
Therefore any methods you create in a class that implements an IDL defined interface, that are outside that interface, are completely free and outside the CORBA system.
The parameters and return types of these 'local native' methods should be java classes. All methods and variables outside the IDL spec will only be visible to the local JVM.

PS - there is a zip file containing a very long and fairly messy demo of this behaviour at http://clio.mit.csu.edu.au/subjects/itc327/Asg2Demo.zip
it has an html file which describes using additional non-IDL 'local native' methods for implementing a save/load function -
Best way to use CORBA 3 with Oracle
Hi, developers,
I was using Oracle 8i JVM with my CORBA server deployed without any problems. That was CORBA 2 with old BOA.
Now I have to implement CORBA 2.3 (I've met the "valuetype" in my new IDL definition). I've successfully compiled the IDL file with JDeveloper 9i (which uses the Visibroker's 4 idl2java compiler). The output was the heap of *.java including *POA.java files. I can not deploy them even when I use the Oracle9i database server.
1) Can anybody show me the way (or multiple ways) to create and to run the CORBA server with POA in the Oracle environment.
2) Is it possible to compile the IDL file (with valuetype statement) with -boa option and to use the output as it is shown in examples included in database server.
3) Are there any good links to find the documentation which could describe the CORBA client/server developing process with the help of JDeveloper.
Thanks in advance,
AndrewForget about using Corba with an oracle product.
I tried to connect a C++ corba client. It is supposed to work. But the guys who wrote the implementation don't work for Oracle anymore. The samples can't be compiled or linked because they use an old ORB.
Oracle support doesn't want to answer with a working solution (even if we PAY for support).
It is probably possible to use an old version of corba with java. I won't be surprised if it is dropped from a future version of the db or application server.
Try to use another solution (ejb, webservice, ...)
Good luck,

RE: Forte/CORBA inquiry - Long post
Dave,
Are you using any kind of structured object in the parameters to your
CORBA-exposed method?
We have found that Forté will change the order of struct class attributes
when changes are made in the IDE (often even when seemingly unrelated).
Look at the IDL generated in your last deploy to be sure the order of
attributes is the same.

Hello,
I've been experimenting with accessing Forte through Java via CORBA. While
I have adequate experience with Forte and Java, I'm fairly new to CORBA. As
a result, I've discovered some issues which I can't seem to resolve.
I fear my explanation might be a bit lengthy, but I figure it's easier to
offer
comments when you have all the information. I apologize in advance.
I started by writing a Java application that would access a Forte service
object.
To keep things simple, I didn't use any of our existing code base. I
instead
used the code examples in tech note #10950: Forte Service Objects and
VisiBroker
Java IIOP clients. However, instead of using the VisiBroker ORB, I used the
Java 1.2 ORB. Other than that, I used the same code offered in the tech
note.
This example worked fine. I exported the IDL from Forte, ran the Sun
idltojava
tool, and compiled my Java classes.
I then tried to carry this example forward, and use some of our existing
Forte
objects. Things did not go as smoothly, and I am now left with a few
questions.
I created two new projects in my workspace - CorbaSO and CorbaManager.
In the CorbaManager I created a single class - CustomerManager. This object
has one method which retrieves a customer object based upon a CustomerID
which
is passed into the method. This project has three supplier plans which are
needed to retrieve this Customer object.
In the CorbaSO project, I created two classes - CorbaServer and TestClass.
CorbaServer has two methods: getCustomer and GetDamage. The getCustomer
method
instantiates an instance of the CustomerManager class, and uses it to
retrieve
a customer based upon the CustomerID passed into the getCustomer method,
then
returns the CustomerName (string). The GetDamage method is the same method
that's used in tech note #10950 (discussed above). I just wanted to make
sure
it still worked. I then made a Service Object from the CorbaServer class,
which
I called CorabaServerSO. This project has two supplier plans - the
CorbaManager
project discussed above, and the plan which contains the CustomerObject
(which
is returned by the CUstomerManager class).
Lastly, the test class simply contains a go() method, which I used to make
sure
the CorbaServerSO was working fine. All it does is call
CorbaServerSO.getCustomerName()
passing in a CustomerID, and writes the returning name out the logger.
The code compiles, and it works fine when I run it from within Forte
[through
TestClass.go()]. I then deployed the app and exported the IDL.
However, when looking at the IDL, I find that Forte exported 900k of IDL.
It
exported the IDL definition of every class within the supplier plan
hierarchy.
Given that I only wanted to expose my one service object, I assumed that I
would only get IDL for that one project. Instead, I got IDL for every
object
all the way down the Supplier Plan chain. So my first question is, why do I
get IDL for everything?
To make matters worse, this 900k IDL file is littered with errors - and my
IDL
compiler chokes. I edited the IDL so that it only contained definitions for
the CorbaSO project, and ran the IDLTOJAVA tool on that edited file. That
created
the JAVA files just fine, and I then compiled them into CLASS files. So far
so good.
I then wrote a Java client to call methods on my newly published
CorbaServerSO.
I found that the GetDamage() method worked fine, while the getCustomer
method
yield the following error: 'org.omg.CORBA.UNKNOWN: minor code: 1
completed:
Maybe'. This error is offered immediately after calling the getCustomer
method
on the CORBA stub.
Curious as to why one method worked, and one didn't - I looked to the code
in
the GetDamage method. The code was as follows (all undeclared variables are
input or output variables of type double):
tmp1 : i4;
tmp1 = i4(total * 0.0775 * 100.0 + 0.5);
salesTax = double(tmp1) / 100.0;
tmp1 = i4(total * 0.15 * 100.0 + 0.5);
tips15 = double(tmp1) / 100.0;
newTotalwoTips = salesTax + total + total;
As written above, the code works. I then modified the code to the following
(all parameters were unchanged):
custManager : CustomerManager= new();
tempCustomer : Customer = custManager.fetchCustomer(12345);
tmp1 : i4;
tmp1 = i4(total * 0.0775 * 100.0 + 0.5);
salesTax = double(tmp1) / 100.0;
tmp1 = i4(total * 0.15 * 100.0 + 0.5);
tips15 = double(tmp1) / 100.0;
newTotalwoTips = salesTax + total + total;
After deploying the newly modified code, I find that the GetDamage method
now
does not work. All I did was instanstiate an object, and call a method on
it.
I never did anything with the results. Yet I get the same error:
'org.omg.CORBA.UNKNOWN:
minor code: 1 completed: Maybe'.
So my two question are:
1. Why did I get IDL for every object within the Supplier Plan tree when I
was
only attempting to expose 1 Service Object.
2. Why does a method cease to work via CORBA when I interact with another
object?
Thanks in advance for any help,
-Dave OrtmanIn a previous post, I asked:
<<Why did I get IDL for every object within the Supplier Plan tree when I
was
only attempting to expose 1 Service Object.>>
Since writing this, I have come across tech note #11427 - which mentions use
of a IIOPIgnore extended flag which you can set on objects to suppress IDL
generation. Otherwise, Forte automatically generates IDL for any object
which is marked as Distributed.
Most of our objects are distributed. I set this property on the objects
within the two projects I was working in, and the IDL for these objects was
not created. However, the rest of the objects in the Supplier Plan chain
were still translated to IDL. Am I going to have to set this property on
every object? I don't see how I could be misapplying the property - but you
never know.
<<Why does a method cease to work via CORBA when I interact with another
object?>>
Through the use of putline()'s, I've found that the error is generated
somewhere deeper within our application architecture. It may be a problem
with our code - I'm not sure. I would still be happy to hear any input on
the matter.
Thanks,

Insertion of user defined structure in CORBA ANY
I am using JDK 1.4.2 CORBA (ORB) APIs.
I am using CORBA Any in my application. I am able to insert primitive values like short, long, char, etc. into the Any using the specified APIs. But if I try to insert a user defined structure, I get an exception.
This can be explained further by the code below:
Consider the following IDL definition:
// IDL
struct Foo {
string bar;
float number;
interface Flexible {
void doit (in any a);
Now in order to pass the structure Foo in Any, I use the following code snippet:
// Java
// Client.java,
import org.omg.CORBA.*;
Flexible fRef;
Any param = ORB.init().create_any();
Foo toPass = new Foo();
toPass.bar = "Bar";
toPass.number = (float) 34.5;
try {
fRef = FlexibleHelper.bind("anyMarker:anyServer", hostname);
fooHelper.insert (param, toPass);
fref.doit (param);
catch (Exception e) {
But I get an exception when I use the above mentioned methodology.
What is that I am doing wrong.
Or is there some known issue with Sun Java ORB.I just noticed that these files appear to be under copyright. My first question is do you have the copyright permissions to post them in a public forum? If not then you may wish to delete them. That being said I have examined the code and it seems easy enough to work around your issues (provided you have the copyright permissions). The way to work around the issues is indeed to replace the struct fields with variables. This will of course require you to change a couple function definitions to input and output the neccesary variables which I believe was at most 5 variables. You will also need to redo the error checking code that uses a cell array. Altogether I estimate about 30 minutes of work. I would have given you the work around in these files had the files not been copyrighted. So, unfortunately, you will have to implement the work around yourself.
Good luck!

Hi we have a little corba project at school with a refferee (the server) and Players.
All Players are Actor Objects which the idl created with stub and everything. the implementation of Actor is Speler (actually it extends _ActorImplBase, but in my limited knowledge of corba this is the same).
I have created a class called politician (in a different package) which extends Speler and all works fine.
Actor's can send requests to eachother because they receive a list of all Actor's on-line. in a request the sender and receiver are stated as Actor's.
I am trying to cast the sender back to my new class (Politician), but it says it is an Actor_Stub. I also tried Object.getClass().getName().getPackage() but it still says it is an stub. But by my knowledge Politician extended Actor and by doing so the stub, right ????
Speler Objects are created like Speler player =new Speler and Politician's like Speler player = new Politician()
What am i doing wrong here ?
thanks in advantageHi,

I also
tried Object.getClass().getName().getPackage() but it
still says it is an stub. But by my knowledge
Politician extended Actor and by doing so the stub,
right ????I am not sure what you are trying to say but I guess that you try to 'cast' an Speler object to an Politician object, right ?
A corba stub can�t be cast in a normal way but must be narrowed.
Is this object received by a remote call (seems to me because you are talking about a stub)? if so, you must narrow it using the Corba helper classes which are generated out of the idl file. This means that you also have to provide an idl definition for your politician objects. the politician interface should de derived from the Actor interface.

Hi,
I need documentation about j2ee cas com bridge. I know that is not still supported but I have to mantain a software that was developed in vb6 using .class files. I have to check something but I haven't the documentation. Does someone knows where I can find it?
Thanks
ValyThere is now an IBM product available for free download.
See http://www.alphaworks.ibm.com/tech/dtjcb?open&S_TACT=104AHW61&S_CMP=GR&ca=dgr-eclpsw02awdtjcb
I have been trying today to investigate migrating from CASCOM to this product. It appears to have the facilities I need (i.e. COM client to Java Server) but I'm having trouble trying to 'match' the two products.
CASCOM can generate TLB files for use by the COM application direct from the Java class, whereas it appears that you have to provide IDL definitions for all Interfaces from scratch, and then convert them to TLBs using 'midl'. Anyone been through a migration already who could share their experiences??
Thanks

Re: Errors compiling the rmi-iiop example.
As I said, apparently, you are trying to compile the IDL client in java using the RMI client classes. THere are two problems with this:
1-- you must compile the rmi class definitions into a directory that can be easily excluded from the class path at the time you compile the idl definitions.
2-- the idl definitions and the resulting classes are useless wrt the rmi definitions and wls, so the resulting classes must be compiled into directories other than those used by wls and the rmi clients.
Another way to look at this is as follows:
To compile the rmi definitions, you do:
set ORIGINALCLASSPATH=CLASSPATH
set CLASSPATH=../fooclasses;$CLASSPATH
javac -d ../fooclasses rmi/FooImpl.java
Then,
-- you compile the jrmp classes as:
rmic -d ../jrmpclasses rmi.FooImpl
-- you compile the weblogic classes as:
java weblogic.rmic -d ../wlsclasses rmi.FooImpl
that is, you are allowed to compile from the same implementation class so long as it is compliant
-- you compile the rmi-iiop classes as:
java weblogic.rmic -iiop -d ../rmiiiopclasses rmi.FooImpl
that is, as with jrmp and wls, the rmi-iiop classes share the same base type definitions and implementation.
However, the idl classes are another matter. To compile the idl classes, you must generate the idl, generate the java files and generate the idl class files into another, separate directory, one which does not include any of ../fooclasses, ../jrmpclasses, ../wlsclasses or ../rmiiiopclasses
directories.
That is,
java weblogic.rmic -idlDirtecory ../idl ...
set CLASSPATH=ORIGINALCLASSPATH
set CLASSPATH=../idlclasses;CLASSPATH
cd ../idl
idl2java rmi/Foo.idl
javac -d ../idl rmi/*.java
Hope this helps...

I'd like to invoke an EJB using the CORBA interface.
I know that "ejbc" generates the CORBA IDL definitions. Do I then invoke
"idlj" on these IDL files to generate the client stubs, or is there a better
way? Will these client stubs work from a WebLogic 5.1 container?
Thanks,

I saw this topic in an old thread but couldn't find the answer. My
problem was the same, the client app was stuck at the line
obj = nc.resolve(path);
Could you post your solution if you know the answer to this problem.
Thanks a lot.Yes, you are right. I'm currently using jdk1.3. Is there a fix or do I
have to go back to jdk1.2? Thanks a lot.

Eduardo Ceballos wrote:
As I said, apparently, you are trying to compile the IDL
client in java using the RMI client classes. THere are two
problems with this:
1-- you must compile the rmi class definitions into a
directory that can be easily excluded from the class path at
the time you compile the idl definitions.
2-- the idl definitions and the resulting classes are useless
wrt the rmi definitions and wls, so the resulting classes must
be compiled into directories other than those used by wls and
the rmi clients.
Another way to look at this is as follows:
To compile the rmi definitions, you do:
set ORIGINALCLASSPATH=CLASSPATH
set CLASSPATH=../fooclasses;$CLASSPATH
javac -d ../fooclasses rmi/FooImpl.java
Then,
-- you compile the jrmp classes as:
rmic -d ../jrmpclasses rmi.FooImpl
-- you compile the weblogic classes as:
java weblogic.rmic -d ../wlsclasses rmi.FooImpl
that is, you are allowed to compile from the same
implementation class so long as it is compliant
-- you compile the rmi-iiop classes as:
java weblogic.rmic -iiop -d ../rmiiiopclasses rmi.FooImpl
that is, as with jrmp and wls, the rmi-iiop classes share the
same base type definitions and implementation.
However, the idl classes are another matter. To compile the
idl classes, you must generate the idl, generate the java
files and generate the idl class files into another, separate
directory, one which does not include any of ../fooclasses,
../jrmpclasses, ../wlsclasses or ../rmiiiopclasses
directories.
That is,
java weblogic.rmic -idlDirtecory ../idl ...
set CLASSPATH=ORIGINALCLASSPATH
set CLASSPATH=../idlclasses;CLASSPATH
cd ../idl
idl2java rmi/Foo.idl
javac -d ../idl rmi/*.java
Hope this helps...

Hi I'm currently working on an IDL compiler and was wondering if somebody can help me with a regular expression I use to read out methods from an IDL file.
this.methodPattern = Pattern.compile("\\s*" +
"(\\w+)" +
"\\s+(\\w+)\\s*" +
"[\\(]\\s*" +
"(?:(?:\\s*?(\\w+)\\s*(\\w+)\\s*?[,]?)?)*" +
"[\\)]" +
"\\s*(?:\\s*raises\\s*(\\w+))?;");
Now this is supposed to match something like
String abc(int a, int b, int c) raises RemoteException
which it does :)
The problem lies with the '+' quantifier which overwrites my parameters, now it only stores the last parameter in this case it would store:
group(i) -> int
group(i+1) -> c
The problem only lies in the highlighted part of the code, the rest is matched and stored properly.
it overwrites the previous parameters, is there a way to store all parameters instead of only the last one? I thought the + quantifier wouldn't cause issues like that.
I'm using JRE 1.6
If someone has an idea as to what I can do in this situation I would be most grateful for suggestions.
- I know I could just match the whole contents and the split the String into an Array, however I would prefer to keep it to one Pattern.You probably want a compiler generator like
ANTLR or
JavaCC.Note that JavaCC has an IDL grammar; you can get it here:
https://javacc.dev.java.net/servlets/ProjectDocumentList?folderID=110&expandFolder=110&folderID=0
To use it, download it and do something like this:
$ cat Hello.idl
module HelloApp
interface HelloCallback
void callback(in string message);
interface Hello
string sayHello(in HelloCallback objRef, in string message);
$ javacc IDL.jj && javac *.java && java IDLParser Hello.idl

hi,
I have one idl interface like this:
interface Konto
attribute double Kontostand;
attribute string Inhaber;
attribute long Kontonummer;
void addPropertyChangeListener(in PropertyChangeListener o);
but the last method raises an error. I understand why, PropertyChangeListener is a Datatype, which doesnt exist. But how can in solve this problem? exist in IDL something like "import" or similar, so that he can find the datatype in the java class library?
thank you
christianYou can only use IDL types in an IDL definition. Is PropertyChangeListener defined in IDL somewhere or is it only defined in Java?

Could someone tell me the relationship between Solaris MC and Sun Cluster?
Thanks!
BillSolaris MC is a distributed operating system for
multi-computers (i.e., clusters of nodes) that provides a
single-system image: a cluster appears to the user and applications
as a single computer running the SolarisTM operating system. Solaris
MC is built as a set of extensions to the base Solaris UNIX � system
and provides the same ABI/API as Solaris, running unmodified
applications. The components of Solaris MC are implemented in C++
through a CORBA-compliant object-oriented system with all new services
defined by the IDL definition language. Objects communicate through a
runtime system that borrows from Solaris doors and Spring
subcontracts. Solaris MC is designed for high availability: if a node
fails, the remaining nodes remain operational. Solaris MC has a
distributed caching file system with UNIX consistency semantics,
based on the Spring virtual memory and file system architecture.
Process operations are extended across the cluster, including remote
process execution and a global /proc file system. The external network
is transparently accessible from any node in the cluster. -
IDL does not support recursive definition??��previous topic is depreciated��
Question1��
interface A{
typedef A AList[];
attribute string name;
attribute A aa; //accepted by idlj,ok
attribute AList aaList; //idlj does not accept such syntax��how to define the attribute whose type is the array of Node,i.e. "Node[]" ??
Question2��
struct Node{
string name;
sequence<Node> children; //accepted by idlj,ok
Node parent; //idlj does not accept such syntax��how to define the attribute whose type is Node itself??
Ur reply will be greatly appreciated!
Thanks a lot!You could always define the parent to be a sequence as well.....
struct Node{
string name;
sequence <Node> children;
sequence <Node> parents;
where the parents sequence would only be length 1 during rumetime....

RCA Connection Pool idle Time-Out takes no effect !
My question description goes here.
According to JCA specification, I developed my 'ManagedConnectionImpl' class from the interface 'ManagedConnection'. I realize the 'destroy()' function to send out logout request to the EIS.
Then I deployed the connector in Sun Java System Application Server, I noticed there are two parameters in Connection Pool part, they are:
1. Idle Timeout. It said it's the maximum time that a connection can remain idle in the pool. I assume the connection will be removed after the specific time expired and before it's removed it will call the recallable function, 'destroy()', in my concrete class, 'ManagedConnectionImpl'.
2. Pool Resize Quantity. it said it's number of connections to be removed when pool idle time expired.
I am weird about it. I think EIS had itself session control strategy, if the specific session time-out expired, it will invalidate this session. So I think we will set 'Idle Timeout' in application server to be shorter than the EIS session time-out. If the 'Idle Timeout' in application server expired, it should remove all connections inside otherwise maybe the connection with invalid session will exist! (the background knowledge is our system will return back soap fault when it meets invalid session, so the invalid connections will not be removed by switching on your configuration item, 'On Any Failure')
So I set "inital and minimum pool size" to 8, "maximum pool size" to 32 and "Pool Resize Quantity" to 32. (I expect AS to remove all when pool idle time expired)
After deploying, I send out requests at the first round and wait for the time expired but I can't see the desired logout requests from pool automatically even one. Firstly I guess if my recallable function definition is wrong but when I shut down the Application Server, the desired logout requests are sent out from pool automatically. So I think my recallable function definition is workable.
What's your comments on it?
P.S.
I am using Sun Java System Application Server 8.1.
Thanks in advance!
