Error in running EJB Client on a remote machine

I delploy my beans and can run the EJB Client locally. However when I try to run the Client on another machine, there are errors.
Here is the errors
Syntax error
Out of environment space
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/enterprise/appclient/Main
I have follow the step in the j2ee tutorial and set the env variables according. Here is the bat file I write
set APPCPATH=CBSAppClient.jar
set VMARGS=-Dj2eelogin.name=guest -Dj2eelogin.password=guest123 -Dorg.omg.CORBA.ORBInitialHost=192.168.0.2
runclient -client CBSApp.ear -name CBSClient -textauth
Do anyone facing the same problem with me?
And how can I solve the problems?
This is really URGENT, please help

You are running on Windows 9x or Me, right? The darn OS has 300 or so bytes allocated for environment by default.
Try setting the Initial environment to 4096 in the Properties|Memory tab for the batch file. That will get rid of "Out of environment space". The syntax error is another matter; Windows (except NT and derivatives) shells do not allow '=' in an environment variables value. You cannot overcome that. Some software (Sybase for instance) interprets # as = just because of that. Unfortunately, the JVM doesn't take such an approach.
Better, grab copies of Unix utilities for Windows (www.gnu.org) including the wonderful shell 'bash' and write .sh scripts, which are inherently more powerful.

... but you did deploy it to an application server, right?

The server deploy EJB but I run EJB Client program,The error msg is can't find JNDI

Hi all:
I am using Weblogic 6.1/SP2. I use the console to start
server and deploy EJB jar,from the msg I see my EJB jar
been deployed. When I run EJB Client program, the error
msg is can't find JNDI name t3://URL:11003.....
I check my ejb-jar.xml amd weblogic-ejb-jar.xml are fine.
Last week I did deploy EJB and ran the client both
suceessful. Any ideas, Thank you.

Sabha:
Thank you for your help info, I soloved the problem.
The problem is the ejb jar was deleted(I don't why)
then System Admin to deploy EJB jar from Admin console.
After that everything is fine.
"Sabha" <[email protected]> wrote:
Run weblogic.Admin -url ... LIST to see whether the JNDI name is there
. or
you can view the jndi tree of the server from the console (right click
on
server name) and check whether the ejb home is bound to the correct jndi
name.

Hi Albert,
I would double check to make sure the EJB was indeed deployed (check
server log). What message did you see that leads you to believe itwas
successfully deployed? Also, verify the JNDI name you are lookingup in
your client matches the JNDI name for the EJB. If this doesn't solve
the problem, please post the error message and stack trace you are
seeing on the client.

How can I run EJB Client in other computer ?

Hello,
I'm trying to run converter examples.
if ejb client pgm resides on a same machine with j2ee server , it works fine.
But when I put client pgm on a different maching
below message show.
No application client descriptors defined for: ConverterClinet
I put ConverterApp.ear, ConverterAppClient.jar and ConverterClient.class on the machine and
set APPCPATH=ConverterAppClient.jar
set VMARGS=-Dorg.omg.CORBA.ORBInitialHost=xxx.xxx.xx.xx
What should I do to run ejb client on different machine?

Hi SangHPark,
I had the same problem but have solved it and it works.
I ran the client remotely from a win98 box.
Keep two things in mind
1> Deploy the applications to an ip address and not to the local host using the deploy too. Use the deploy tool Gui to add a new server and then deploy the application to this ip address.
2> I am running j2ee version 1.3 and jsdk 1.3
Use the following code but instead of using "java:comp/env/ejb/SimpleConverter" use the jndi name of the object: "MyConverter" as specified in the tutorial.
Properties prop = new Properties();
prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,"com.sun.enterprise.naming.SerialInitContextFactory");
prop.setProperty(Context.PROVIDER_URL,"IIOP://xxx.xx.x.xxx:1050");
System.out.println("Attempting to create context...");
Context initial = new InitialContext(prop);
// Instead of this use the below line of code
//Object objref = initial.lookup("java:comp/env/ejb/SimpleConverter");
Object objref = initial.lookup("MyConverter");
// MyConverter is the Jndi name of the ConverterBean as per the tutorial
You need to do the following things.
1> After making changes to the code recompile using Ant and redeploy it.
2> Copy the j2ee.jar, ConverterAppClient.jar and ConverterClient.class file to the machine that u want to run the client from.
3> create a directory called "config" on the remote machine where you copied the files in step two.
4> Copy to this directory the files ejb.properties and security.properties from your j2ee_home\config\ directory.
For example you copied the files in step 2 on the remote machine in the c:\test directory. Create c:\test\config directory and copy the files from step 4 into this directory.
5> Run the following command from the directory where u copied the client files
java -Dorg.omg.CORBA.ORBInitialHost="host name" -classpath .\j2ee.jar;.;.\ConverterAppClient.jar ConverterClient

Error in calling EJB Client from Remote Machine.

While running the client from local machine, it works perfectly.
But when I try to run the same client from remote machine it gives me the error.
I deployed the ejb in sun server 1.4 with jndi as "xxx.xxx.xxx.xxx/MyTemperature".
Following is the code snippet from the clint.
Context initial = new InitialContext();
          Object objref = initial.lookup("192.168.0.20/MyTemperature");
          home = (TemperatureHome) PortableRemoteObject.narrow(objref, TemperatureHome.class);

I also tried with java.util.Properties class but result is same.

You are running on Windows 9x or Me, right? The darn OS has 300 or so bytes allocated for environment by default.
Try setting the Initial environment to 4096 in the Properties|Memory tab for the batch file. That will get rid of "Out of environment space". The syntax error is another matter; Windows (except NT and derivatives) shells do not allow '=' in an environment variables value. You cannot overcome that. Some software (Sybase for instance) interprets # as = just because of that. Unfortunately, the JVM doesn't take such an approach.
Better, grab copies of Unix utilities for Windows (www.gnu.org) including the wonderful shell 'bash' and write .sh scripts, which are inherently more powerful.

Running a J2EE client on a Remote machine

How do you run a J2EE client application on a remote machine?

and what about running on remote client .
the things i know is , ok leave i am pasting a client which is on different machine (i.e not on the machine on which the server is ) copy
1. the client jar file which is return when u deploy the beans .
* Remember to add jar path in the class path
2. client class / java file on the remote client
and then run the client
for eg . client code
change Properties 's prop accoding to u
import javax.ejb.*;
import javax.naming.*;
import java.rmi.*;
import javax.rmi.PortableRemoteObject;
import java.util.*;
public class TestClient {
public static void main(String[] args) {
try {
     System.out.println("IDFactory");
     Properties prop = new Properties();
     /* prop.put("org.omg.CORBA.ORBInitialHost","192.168.10.5");
     prop.put("org.omg.CORBA.ORBInitialPort","1050");
     prop.put(Context.PROVIDER_URL, "iiop://192.168.10.5:1050");
     prop.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.cosnaming.CNCtxFactory");
     InitialContext initial = new InitialContext(prop);
     Object objref = initial.lookup("TimeReport/Data/TestHome");
     TestHome home = (TestHome)PortableRemoteObject.narrow(objref,TestHome.class);
     System.out.println("looking up IDFactory Session Bean");
     Test TestRemote = home.create();
     System.out.println("IDFactory Created ");
     long roleID = TestRemote.getID("TR_ROLE","Role_ID");
     System.out.println("RoleID is " + roleID);
     TestRemote.remove();
     } catch (Exception ex)
     System.err.println("Caught an unexpected exception!" + ex.getMessage());
     ex.printStackTrace();
if it works then let know on [email protected]
cheers

How to run ejb client on a separate host using Oracle example

The example I used was under $ORACLE_HOME/javavm/demo/examples/ejb/basic/jdbcimpl
If I used the Makefile provided to run the client and server, it worked ok. Now I tried to move the client to an NT machine and it did not work. (BTW, the server was on a Linux machine.)
What I did was to copy the compiled class and jar files to NT (Client.class, employee/*.class aurora_client.jar, vbjapp.jar, and vbjorb.jar). After I ran it, I got an error in javax.naming.InitialContext.lookup.
I compiled and ran the code using jdk1.1.8. If I recompiled the code on NT using jdk1.3, I got a CORBA.OBJECT_NOT_EXIST error.
Any clue?

Copy the following files to the CT's machines. Copy the server_generated.jar also to the CT's machine. In your case the file will be there in the $ORACLE_HOME/javavm/demo/examples/ejb/basic/jdbcimpl directory.
C:\ORA816\lib\aurora_client.jar;
C:\ORA816\jdbc\lib\classes111.zip; // Replace this with classes12.zip if you are using JDK 1.2.2
C:\ORA816\sqlj\lib\translator.zip; // If you are using SQLJ in the CT's code
C:\ORA816\lib\vbjorb.jar;
C:\ORA816\lib\vbjapp.jar;
server_generated.jar
Set you classpath to include the all the above files.
Oracle 8.1.6 can work with JDK 1.2.2 and JDK 1.1.8. Please try with the JDK 1.2.2 and let us know the results.

-- Error during running JMS client --

Hello ,i m novice in JMS,just trying to Implement my first JMS programming on WL8.1,I m getting error during Run client program
My client program is below :
package examples;
import javax.naming.*;
import javax.jms.*;

Pls Help me
Thnx in Advance ...

First of thanks for gave me a Reply.
(1) System.out.println("Object Retrived "+ctx.lookup("testtopic").toString()); this line is nothing just i wanted to check that program giving me a object or not .and output of this line is
Object Retrived weblogic.jms.client.JMSConnectionFactory@1f66cff
(2)Testtopic is not a object but it is JNDI name whichever i specified in webligic-ejb-jar.xml
(3)i added this line System.out.print("Second output"+ctx.getClass().getName()); and i got this output:
Second output javax.naming.InitialContext
but still i m getting same error

Error in running worflow client

Hi
I have an java class which works as a workflow client. When i run the class i get the error as following:
ORABPEL-10509
User is not found.
User "jcooper" is not found in realm "jazn.com"
The java code i have is like below:
IWorkflowServiceClient wfSvcClient = WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory.JAVA_CLIENT);
System.out.println("Before getting the task query service");
//Get the task query service
ITaskQueryService querySvc = wfSvcClient.getTaskQueryService();
System.out.println("Got the task query service -- "+querySvc);
//Login as jstein
IWorkflowContext ctx = querySvc.authenticate("jcooper",
"welcome1",
oracle.tip.pc.services.identity.config.ISConfiguration.getDefaultRealmName(), //Use default realm
null);//Not logging in on behalf of another user
//Set up list of columns to query
List queryColumns = new ArrayList();
queryColumns.add("TASKID");
queryColumns.add("TASKNUMBER");
queryColumns.add("TITLE");
queryColumns.add("OUTCOME");
//Create a predicate to query tasks that have a null outcome
String outcome = null;
Predicate predicate = new Predicate(TableConstants.WFTASK_OUTCOME_COLUMN,
Predicate.OP_EQ,
outcome);
//Create an ordering to order tasks by task number
Ordering ordering = new Ordering(TableConstants.WFTASK_TASKNUMBER_COLUMN
,true //Ascending order
,false //Nulls last
//Query a list of tasks assigned to jstein
List tasks = querySvc.queryTasks(ctx,
queryColumns,
null, //Do not query additional info
ITaskQueryService.ASSIGNMENT_FILTER_MY,
null, //No keywords
null, //Only tasks with no outome set
ordering, //Order by ascending task number
0, //Do not page the query result
0);
//Get the task service
ITaskService taskSvc = wfSvcClient.getTaskService();
ArrayList retTasks = new ArrayList();
//Loop over the tasks, outputting task information, and approving tasks
for(int i = 0 ; i < tasks.size() ; i ++)
Task task = (Task)tasks.get(i);
int taskNumber = task.getSystemAttributes().getTaskNumber();
String title = task.getTitle();
String taskId = task.getSystemAttributes().getTaskId();
retTasks.add(taskId);
return retTasks;
I have also added all the jars as per the following in the BPEL dev guide:
http://iasdocs/iasdl/101310_final/integrate.1013/b28981/worklist.htm#CIHGEABG
Could anyone tell me what the problem could be here?
Thanks

Are you running the client on the same server? i.e., the code is called from a JSP or a servlet on the same server?
If not, you may use the REMOTE_CLIENT instead of the JAVA_CLIENT, in your call to WorkflowServiceClientFactory.getWorkflowServiceClient(). This forces the user information to be pickedup by the workflow service on the server.

Hi
Please do a fetch from the database and then change the information in DRM console for the CSS parameter. This error I received only due to the CSS details in DRM 11.1.2.

ClassCastException exception while running EJB Client

Folks,
I am getting following exception while running the EJB Client.. I am
using WLS 5.1
Exception in thread "main" java.lang.ClassCastException
at
javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:319)
at FirstStatelessEJBClient.Client.lookupHome(Client.java:149)
at FirstStatelessEJBClient.Client.<init>(Client.java:44)
at FirstStatelessEJBClient.Client.main(Client.java:82)
Can anybody throw a light on this.
Thanks
Ashish

Hi Eduardo,
Below is my classpath. The stubs are in first_statlessSession.jar file.
CLASSPATH=C:\weblogic\myserver\first_statelessSession.jar;
C:\jdk1.2.2\lib\tools.jar;C:\weblogic\license;C:\weblogic\classes;C:\weblogi
c\lib\weblogicaux.jar;
C:\weblogic\myserver\clientclasses;C:\weblogic\myserver\serverclasses
Also, I am just compiling and deploying the
C:\weblogic\examples\ejb\basic\statelessSession myself and testing it. I
am
using the build.cmd files to compile and deploy the above EJB. If I use the
jars provided by weblogic it works fine with same above classpath.
I don't know what to do next. I have invested the whole day to solve this
problem and couldn't.
Please let me know if I am doing anything wrong.
Appreciate your help.
Thanks,
Ashish
