UnmarshalException with nested EOFException on Naming.lookup()

I have an RMI server object that creates its own RMI registry and binds, like this:
     Registry registry = LocateRegistry.createRegistry(1099);
     registry.bind("JournalReceiver", this);I run this from the command line to get it started. Everything looks good.
My client is running as a webapp in Tomcat (on the same machine), and it executes this call:
        receiver = (RmiJournalReceiverInterface) Naming.lookup("JournalReceiver");and gets this error
java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
     java.io.EOFException
     at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source)
     at java.rmi.Naming.lookup(Naming.java:84)It is clear that I'm reaching the registry, and if I modify the code to intentionally lookup the wrong name I get a "not bound error", so I'm pretty confident that my server object is indeed bound to that name. Beyond that, I'm lost.
Any thoughts?

OK - the problem was an incorrect codebase.
My server object creates its own registry with
       Registry registry = LocateRegistry.createRegistry(1099);
     registry.bind("JournalReceiver", this);and I get the UnmarshalException with nested EOFException, as shown above.
However, if I set up an outside registry with 'rmiregistry', and use
        Naming.rebind("JournalReceiver", this)then I get the UnmarshalException with nested ClassNotFoundException, which has shown up in several threads.
So, following the advice given in those threads, I fix the codebase like this:
java -Djava.rmi.server.codebase=file:/var/local/jb/RmiReceiver.jar \
   org.nsdl.RmiJournalReceiverand it works as advertised, even when I go back to my original lines of binding code.
Thanks again for the help.

RMI Client UnmarshalException with UNC paths

I have a 'none' Java application, that has an embedded JVM which is being used as an RMI server to allow communication to the application from a browser. The applet detects the presence of the RMI server and if not detected, will start the application, which in turns starts the RMI server. Once the RMI server is started the Client then invokes the method on the server, and hence into the application.
If the executable for this application is pathed to either a local or mapped drive then everything works as expected, if I then try to use a UNC path, once the RMI server is started, the client returns an UnmarshalException:
java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is:
java.io.EOFException
java.io.EOFException
at java.io.DataInputStream.readByte(Unknown Source)
at sun.rmi.transport.StreamRemoteCall.executeCall(Unknown Source)
at sun.rmi.server.UnicastRef.invoke(Unknown Source)
at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source)
at java.rmi.Naming.lookup(Unknown Source)
I guess that the problem is that the serialization process has been started, and as the client starts reading from the datastream the UNC paths cause the EOF Exception. any help on how to get round this problem would be gratefully received. Unfortunately using a mapped drive is not a solution to this problem due to the way the application is being served.

Hi all,
It turns out that when the java.policy file is being read, it ignores the servername on the UNC path and therefore looks for a directory of the remaining data of the UNC path for the file. I guess it is now a task of figuring out why this is...

UnmarshalException with SocketException

Hey guys!
I am working a rmi system. I have a problem when I go to run my Server class. I get an UnmarshalException, with a nested exception: java.net.SocketException: connection reset by peer. I have no idea why...it is killing me. If any body has any suggestions, please feel free to let me know...
See ya!
Cardwell

. Since it is the exception
occured
while unmarshalling the parameters But I don't know
this
process happens on which side, server or client. As far as I know unmarshalling takes place at the reciever side, on reciept of a transmission. So it can be either side. The registry unmarshalls the arguments using the codebase and the when the client calls Naming.lookup it unmarshals the result as well.
Do let me know if I am wrong?

Naming.lookup refuses to work properly when I use a different port

Ok, here's the deal: I have an application that uses RMI. Until now it has worked wonderfully, but since a new service that "steals" port 1099 is going to be installed on the same machine, I have to update my code to start working with another port.
Nothing unfathomable, of course. Or so I thought.
I start the registry with the right port (1211) and I bind my server using the same port:
Naming.rebind("//localhost:1211/XXX", myXXX)But when I try to get a reference to that object by using Naming.lookup("//localhost:1211/XXX")I get a nasty UnknownHostException!
And here's the freakish thing: if I try this...
String[ ] list = Naming.list("//localhost:1211");
for(int i=0; i<list.length; i++) {
System.out.println(list);
XXX myObj = (XXX)Naming.lookup("//localhost:1211/XXX")
...first I get a list of the objects contained in the registry, and my "//localhost:1211/XXX" [i]is there, but then when I look it up, I get the exception that says my host 172.x.x.x (the localhost) is unknown!
I have made sure there are no unwanted blank spaces in the Strings i use for the binding and lookup. I have even tried using the very String that I receive from Naming.list, but nothing works.
Any ideas? It works like a charm when I simply eliminate ":1211" everywhere in the code. I appreciate any help I can get.

Do you really get the exception on the lookup or when using the stub? Can you post the full exception text and stack trace?

Naming.lookup() returns null???? Why??

I read about this in a previous forum but there was no answer given to someones question about it. Sometimes Naming.lookup() returns null and a later call will succeed. Is there a recognised reason for this? Is it a recognised bug or undocumented feature?
I have seen some sample RMI source on the Internet and sometimes the code checks for null and gives and error. The sample programs from Sun regarding RMI don't check for null.
Has anyone ever encountered this and found a way around it?
Thanks for you help,
Anthony

hi
are you using an Activatable object??
then, it can happens, since you won't have your object until the ActivationSytem is running.
And it takes little time for the activation system to run.
If u are using an 'Activatable object, i will suggest to write a loop in which you check if hte ActivationSystem was started.
something like this
boolean display = false;
ActivationGroupID agi = null;
while(true) {
try {
if(!display) {
System.err.println("Trying to connect to ActivationSystem...");
display = !display;
agi = ActivationGroup.getSystem().registerGroup(exampleGroup);
break;
} catch(Exception e) {
continue;
}

Issues with nested for loops - saving images from a camera

Hi all,
I've written a vi. to capture a specific number of images ('Image No') and save these images, outputted to a folder of my choice. Each image is identified sequentially. However, I wish to do a number of iterations ('Run') of this capture sequence, such that the filename of each image would be 'Filename (Run)_(Image No).png', e.g. run 5, image 10 would be 'Filename 5_10.png'. I have tried a nested for loop for this but I receive an error 'Asynchronous I/O operation in progress' (I've attached a printscreen).
Can anyone assist me in solving this problem? I preiously posted this in machine Vision but got no response (http://forums.ni.com/t5/Machine-Vision/Capturing-image-sequences-issues-with-nested-for-loops/m-p/19...). Please find attached my vi.
Kindest regards and thanks,

Miika,
the problem is not the filenam, but the name of the folder (AHHHHH!). You try to create the same folder in the outer for loop over and over again.... (it is the error message above the '======', not below )

How to set the screen size with nested Iview screen

Can someone show me how to set the screen size with nested IView screen.
at the moment i only try it with trial and error untill it looks somewhat close. Is there a property in VC to set the size for Height and width.
The same question is for the form. the form elements inside the form is easy but the actual form is still a challenge.

Hi,
Yes you are correct ,Still the Form and iview are not able to change thier Layout Structure using a Propery.
it is available with VC7.1

Custom taglib with nested tag not working

Hi everybody,
I have a question concerning a custom taglib. I want to create a tag with nested child tags. The parent tag is some kind of iterator, the child elements shall do something with each iterated object. The parent tag extends BodyTagSupport, i have overriden the methods doInitBody and doAfterBody. doInitBody initializes the iterator and puts the first object in the pageContext to be used by the child tag. doAfterBody gets the next iterator object and puts that in the pageContext, if possible. It returns with BodyTag.EVAL_BODY_AGAIN when another object is available, otherwise BodyTag.SKIP_BODY.
The child tag extends SimpleTagSupport and does something with the given object, if it's there.
In the tld-file I have configured both tags with name, class and body-content (tagdependent for the parent, empty for the child).
The parent tag is being executed as I expected. But unfortunately the nested child tag does not get executed. If I define that one outside of its parent, it works fine (without object, of course).
Can somebody tell me what I might have missed? Do I have to do something special with a nested tag inside a custom tag?
Any help is greatly appreciated!
Thanks a lot in advance!
Greetings,
Peter

Hi again,
unfortunately this didn't work.
I prepared a simple example to show what isn't working. Perhaps it's easier then to show what my problem is:
I have the following two tag classes:
public class TestIterator extends BodyTagSupport {
    private Iterator testIteratorChild;
    @Override
    public void doInitBody() throws JspException {
        super.doInitBody();
        System.out.println("TestIterator: doInitBody");
        List list = Arrays.asList(new String[] { "one", "two", "three" });
        testIteratorChild = list.iterator();
    @Override
    public int doAfterBody() throws JspException {
        int result = BodyTag.SKIP_BODY;
        System.out.println("TestIterator: doAfterBody");
        if (testIteratorChild.hasNext()) {
            pageContext.setAttribute("child", testIteratorChild.next());
            result = BodyTag.EVAL_BODY_AGAIN;
        return result;
public class TestIteratorChild extends SimpleTagSupport {
    @Override
    public void doTag() throws JspException, IOException {
        super.doTag();
        System.out.println(getJspContext().getAttribute("child"));
        System.out.println("TestIteratorChild: doTag");
}The Iterator is the parent tag, the Child shall be shown in each iteration. My taglib.tld looks like the following:
<?xml version="1.0" encoding="UTF-8"?>
<taglib
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee web-jsptaglibrary_2_1.xsd"

          <body-content>empty</body-content>
     </tag>
</taglib>And the snippet of my jsp is as follows:
     
     <cms:test-iterator>
          <cms:test-iterator-child />
     </cms:test-iterator>The result is that on my console I get the following output:
09:28:01,656 INFO [STDOUT] TestIterator: doInitBody
09:28:01,656 INFO [STDOUT] TestIterator: doAfterBody
09:28:01,656 INFO [STDOUT] TestIterator: doAfterBody
09:28:01,656 INFO [STDOUT] TestIterator: doAfterBody
09:28:01,656 INFO [STDOUT] TestIterator: doAfterBody
So the child is never executed.
It would be a great help if anybody could tell me what's going wrong here.
Thanks and greetings from germany!

Import tables with nested table : ORA-00600

In Oracle 9.2
Create object, type as table, and table with nested table (store as syms_ntab) are successfully.
Also its export.
In process of import on another server (also 9.2, 'fromuser=one touser=two') shows errors:
. . importing table "SYMS_NTAB"
IMP-00058: ORACLE error 600 encountered
ORA-00600: internal error code, arguments: [kokeeafi1], [2], [2], [], [], [], [], []
IMP-00075: Warning: The nested table may contain partial rows or duplicate rows
But for all that table is created and error occur on phase inserting strings.
What is this?
In Oracle 8.0.5 i perform similar operation without error.

From Oracle error messages and codes manual:
ORA-00600 internal error code, arguments: [string], [string], [string], [string], [string], [string], [string], [string]
Cause: This is the generic internal error number for Oracle program exceptions. It indicates that a process has encountered a low-level, unexpected condition. Causes of this message include:
* timeouts
* file corruption
* failed data checks in memory
* hardware, memory, or I/O errors
* incorrectly restored files
The first argument is the internal message number. Other arguments are various numbers, names, and character strings. The numbers may change meanings between different versions of Oracle.
Action: Report this error to Oracle Support Services after gathering the following information:
* events that led up to the error
* the operations that were attempted that led to the error
* the conditions of the operating system and databases at the time of the error
* any unusual circumstances that occurred before receiving the ORA-00600 message
* contents of any trace files generated by the error
* the relevant portions of the Alter files
Note: The cause of this message may manifest itself as different errors at different times. Be aware of the history of errors that occurred before this internal error.

Query rewrites with Nested materialized views with different aggregations

Platform used : Oracle 11g.
Here is a simple fact table (with measures m1,m2) and dimensions (a) Location (b) Calendar and (c) Product. The business problem is that aggregation operator for measure m1,m2 are different along location dimension and Calendar dimension. The intention is to preaggregate the measures for a product along the calendar dimension and Location dimension and store it as materialized views.
The direct option is to define a materialized view with Inline queries (Because of the different aggrergation operator, it is not possible to write a query without Inline query). http://download-uk.oracle.com/docs/cd/B28359_01/server.111/b28313/qradv.htm#BABEAJBF documents the limitations that it works only for 'Text match' and 'Equivalent queries' and that is too limiting.
So decided to have nested materialized view, with first view having just joins(my_dim_mvw_joins), the second view having aggregations along Calendar dimension (my_dim_mvw_calendar) and third view having aggregations along the Location dimension(my_dim_mvw_location). Obviously I do not want the query I fire to know about materialized views and I fire it against the fact table. I see that for the fired query (Which needs aggregations along both Calendar and Location), is rewritten with just second materialized view but not the third. (Had set QUERY_REWRITE_INTEGRITY as TRUSTED) .
Wanted to know whether there are limitations on Query Writes with nested materialized views? Thanks
(Have given a simple testable example below. Pls ignore the values given in 'CALENDAR_IDs', 'PRODUCT_IDs' etc as they are the same for all the queries)

This Query rewrites only with my_dim_mvw_calendar. (as saw in Query Plan and EXPLAIN_MVIEW). But we would like it to use my_dim_mvw_location as that has aggregations for both dimensions.

Hi all,
I'm trying to make my programmer's life easier by creating a database view for them to query the data, so they don't have to worry about joining tables. This sounds like a pretty horrible idea. I say this because you will eventually end up with programmers that know nothing about your data model and how to properly interact with it.
Additionally, what you will get is a developer that takes one of your views and see's that of the 20 columns in it, it has 4 that he needs. If all those 4 columns comes from a simple 2 table join, but the view has 8 tables, you're wasting a tonne of resources by using the view (and heaven forbid they have to join that view to another view to get 4 of the 20 columns from that other view as well).
Ideally you'd write stored routines that satisfy exactly what is required (if you are the database resource and these other programmers are java, .net, etc... based) and the front end developers would call those routines customized for an exact purpose.
Creating views is not bad, but it's by no means a proper solution to having developers not learn or understand SQL and/or the data model.

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

Partition exchange error on table with nested table

On Oracle 11.2.0.1, I have a partitioned table with some partitions that need to be 'archived' (in terms of moving partitions to an 'archive' table).
I have a source table like:
CREATE TABLE IS_PODACI245

ID_OBJEKTA                 NUMBER(20),

/I would like to make exchange partition using stage table, and everything is going fine on all tables, but only on a few of them (listed source is one of them, and they're only tables with nested tables wihin), where I get an error.. but sometimes ;)
on a statement like:
ALTER TABLE IS_PODACI245_ARH EXCHANGE PARTITION P_201106 WITH TABLE IS_PODACI245_STAGE EXCLUDING INDEXES WITHOUT VALIDATION;I got an error:
ORA-00001: unique constraint (TXV.SYS_C0032911) violated
it's an unique index between parent and nested table.
what could cause that problem?

Dear,
I suppose that the unique constraint
ORA-00001: unique constraint (TXV.SYS_C0032911) violatedis the one you 've created on the nested table IS_PODACI245_STORE_TABLE
If so, why not disable that constraint and try again.
I have never exchanged such a kind of partitioned table having a nested table in it. But, I could imagine that the cloned non partitioned table IS_PODACI245_STAGE should at least be the exact image of the partitioned table IS_PODACI245_ARH (of course without the partition part) but with the nested table part and including all indexes
In addition, if you have a parent/child relationship between your partitioned tables, then there is a chronological order of exchange starting by the child and then finishing by the parent
see the following link for more information about this order of exchange (and comment 2 for an example also)

Problem when expanding Tree - Tree with nested table column

Hi, i have created the tree using the Tree with nested table column.
I have created a node called TREE_ROOT in the context.
This node has few attributes which includes children_loaded, is_leaf, is_expanded.
I have created the recursive node TREE_SUB for the above node TREE_ROOT.
In the view, i have created the table with the master column. The above attributes have been mapped accordingly. I have created the action handler for load_children.
In this action handler method, i receive the context_element correctly. In this method, i determine the children of the selected element and the resulting children are attached to this context_element.
But the problem is: when i add elements to context_elements in the method load_children, these
elements get added to the node TREE_ROOT as well.
Please help.
thanks and best regards,
Pramod

I just use some types defined in this user... Well, I hope you know what is the type definition of d_period_sec,
don't you ? I didn't ask to provide all types existed now, only types you are
using.
Anyhow you have been granted with execute privilege for types you are using:

Connected.
SQL> create or replace type d_period_sec as object (date# date);
2 /
Type created.
SQL> grant execute on d_period_sec to public with grant option;

ANSI Standard Join with Nested Table

Does anyone know how to (or whether you actually can) use ansi standard table joins with nested tables.
Non-ansi standard would look something like this
SELECT e.empno
FROM departments d, TABLE(d.employees) e
WHERE d.deptno = 10;
Where d.employees is a nested table.
But if I try ansi-standard I like such:
SELECT e.empno
FROM departments d
JOIN TABLE(d.employees) e
WHERE d.deptno = 10;
I get
ORA-00905: missing keyword
because I have nothing to join it on.
Your help is very much appreciated

Both replies worked fine.
I think I will go with the NATURAL JOIN as it seems the cleanest option.

Fill datagridview with Nested Table Object Type ???

Hello everybody, please you help me resolve my problem?
I follow this example: *(A Sample Application using Object-Relational features)* http://download-west.oracle.com/docs/cd/B14117_01/appdev.101/b10799/adobjxmp.htm
And this tutorial: *(Using Oracle User-Defined Types with .NET and Visual Studio)* http://www.oracle.com/technology/obe/hol08/dotnet/udt/udt_otn.htm
Now I have 3 Object Table: Stock, Customer and Purchase Order. With the tutorial it's OK to show the data of Stock and Customer Table [there is no nested table in], but I can't do this with table Purchase Order, the tutorial don't show how to work with Nested Table type [Missing or something ?]
When I try to display the data of table Purchase Order, I get the error:
typeName='LINEITEMLIST_NTABTYP'' is not specified or is invalid*
Follow the tutorial, I generate custom class for this UDT and get another error:
this.STOCK_REF = ((object)(Oracle.DataAccess.Types.OracleUdt.GetValue(con, pUdt, "STOCK_REF")));*
Argument Exception Unhandle: Object attribute is not mapped to a custom type member.*
Can You show me how to do this ? Show the data of the Nested Table in Visual Studio, do I have something wrong ??? Thanks and Best Regards.

I think you need to go through the tutorial more carefully. I think you are missing steps.
You are using a REF. Are you creating an object table for the objects to be stored in? Are you dereferencing the REF? This is covered by the Oracle by Example tutorial.
http://www.oracle.com/technology/obe/hol08/dotnet/udt/udt_otn.htm#t11
When you receive the nested table, it will be inside a .NET class. You can create this class by using the Create Custom Class menu item on the nested table type in server explorer.
This class will contain a ToString method and a ToXML method.
The question is, where are you attempting to display the data from this nested table? In a grid?
Does it make sense to display a nested table inside one cell of a grid? No. You would need to construct a special UI that will show the
nested table. Maybe the user clicks on the cell on the grid, which opens a new grid that displays the data. Or maybe there is a second grid on the form that always shows the nested table for the row that the first grid currently has selected.
I realize I am not providing you the code... but it sounds like you need to design a more sohisticated UI than what the tutorial is using -- one that can handle displaying one additional table per row.
