Run standalone client

Hello,
I'm new to Weblogic. I wrote a client code used to test the session bean. May I ask how to run a standalone client code in Weblogic workshop?
Thanks in advance.

Hello,
You will be able to do it in WebLogic Workshop. You will need to place the EJB client jar in the server lib folder and create a java project which will contain your client code.
Please post all WebLogic Workshop related issue to the weblogic.developer.interest.workshop newsgroup at http://newsgroups.bea.com/bea/forum.jspa?forumID=2041
Cheers

Issue when a standalone client invoke a method on an EJB

I do a simple ejb (like SayHello sample) and i create a standalone client that call one method of this EJB.
When i run the client i have the following error from the eclipse IDE (Error is thrown at lookup):

The eclipse IDE is runwith the option -vm D:\bea\jdk160_05\bin\java
In eclipse, i configure to use the same jdk.
When i execute the client outside eclipse, all is ok....
Do you have an idée ?
This is the ejb code :
package test;
public interface IHelloWorld {
public static final String JNDI_NAME = "HelloWorld";
public String sayHello( String name);
package test;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.ejb.TransactionAttribute;
import javax.ejb.TransactionAttributeType;
import javax.ejb.TransactionManagement;
import javax.ejb.TransactionManagementType;
@TransactionManagement(TransactionManagementType.CONTAINER)
@TransactionAttribute(TransactionAttributeType.REQUIRED)
@Stateless( name="HelloWorld", mappedName= IHelloWorld.JNDI_NAME)
@Remote( IHelloWorld.class)
public class HelloWorld implements IHelloWorld
public String sayHello (String name) {
final String msg = "Hello " + name + ". The world is wonderfull...";
System.out.println ( msg);
return msg;
This is the client code :
package client;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import test.IHelloWorld;
public class MainHello {
public static void main (String[] args) throws Exception
Hashtable<String, String> properties = new Hashtable<String, String> ();
properties.put (Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
properties.put (Context.PROVIDER_URL, "t3://localhost:7001");
InitialContext ctx = new InitialContext( properties);
IHelloWorld hello = (IHelloWorld)ctx.lookup ( "HelloWorld#test.IHelloWorld");
String result = hello.sayHello ( "franck");
System.out.println ( result);
ctx.close ();
As you can see it is very simple but doesn't work inside eclipse IDE...

Oracle software purchases come with a CSI number that allows customers to have people contact support for products they own. If you or the organization you are working with has not purchased the product or have other support arrangements with Oracle (some partners have this), then you probably will not be able to obtain the patch from Oracle.
You might be able to try a newer release of the product with an OTN evaluation license, WebLogic Server is currently on version 10.3.3, so you are at least 3 releases behind at this point if you are using 10.3.0.

Getting error while running standalone Java application related to Workflow

Hi,
I am using the following code
import oracle.bpel.services.workflow.client.IWorkflowServiceClient;

     String userId = "jcooper";
     String password = "welcome1";
     String taskId = "";
     IWorkflowServiceClient wfSvcClient = WorkflowServiceClientFactory.getWorkflowServiceClient(WorkflowServiceClientFactory.JAVA_CLIENT);
     IWorkflowContext wfCtx = wfSvcClient.getTaskQueryService().authenticate(userId,password,oracle.tip.pc.services.identity.config.ISConfiguration.getDefaultRealmName(),null);
     Task task = wfSvcClient.getTaskQueryService().getTaskDetailsById(wfCtx,taskId);
     List assigneeUsers = task.getSystemAttributes().getAssigneeUsers();
     List assigneeGroups = task.getSystemAttributes().getAssigneeGroups();

     task = wfSvcClient.getTaskService().updateTaskOutcome(wfCtx, task, "Approve");
I have added wf_client_config.xml, wf_config.xml,is_config.xml to the classpath. While executing this java code, i am getting the following error

Kindly help me out.
Thanks,

Hi,
I am not using OID. I am using only JAZN. I copied is_config.xml and wf_config.xml to classes folder where i am running standalone application and also i referred this to the classpath. Kindly do the needful.. I am struggling with this issue for past 3 days.
Another thing is if i am giving the user name as "jcooper" it is throwing the error. If i give "oc4jadmin", then the issue resolved.
kindly tell me what should i do inorder to login as jcooper instead of oc4jadmin
Thanks,
Gomathi

Jax-ws deployed in standalone client fails with nullpointerexception

I have a project which has deployed successfully as a standalone client with deployed jar files wlfullclient.jar, etc. When I add the jax-ws functions that I require, the deployed client fails with a nullpointerexception that is generated from the constructor of the Service class. The project runs successfully within the JDeveloper 11.1.1.5 environment and on a weblogic 10.3 server platform, but fails when I deploy as a standalone client with the wlfullclient.jar. I'm using JDK 1.6.0_24. In testing, the error occurs when I replace the {WLHome}\server\lib\weblogic.jar entry in the classpath with the wlfullclient.jar.
I tested from another angle by creating my jax-ws functions in a standalone deployment, and it works successfully communicates with the webservices. No additional entries on the classpath besides my deployed jar. I then added to my deployment a simple JMS context lookup:
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY, contextFactoryProvider);
ht.put(Context.PROVIDER_URL, urlString);
Context context = new InitialContext(ht);
This test runs without error in the JDeveloper environment. As soon as I add the wlfullclient.jar in the standalone environment, I get the following exception:
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/xml/ws/spi/ProviderImpl

Interestingly, there is a class com/sun/xml/internal/ws.spi/ProviderImpl in the {JAVA_HOME}/jre/lib/rt.jar file, and I suppose this is what is used by the jax-ws classes when the wlfullclient.jar is not present on the classpath.
So, what is it that I am missing in how to get the jax-ws classes and the jms classes to work in the standalone deployment environment (outside of the JDeveloper environment).

Here is how I solved this problem to execute the application from a jar file (using Oracle Fusion Middleware 11.1.1.5.0 distribution). The key seems to be to extract the contents of the wseeclient.zip file into the same directory as the wlfullclient.jar and ws.api_1.1.0.0.jar files and then ensure that these 2 jars are on the classpath.
In JDeveloper, create a project that has the jms/jax-ws classes.
Put the following text entries to form the classpath (along with other dependent jars, e.g. org.eclipse.persistence...) into a file which will be included in the manifest for the client jar. Be sure to separate entries with a space.
lib/wlfullclient.jar lib/wseeclient.jar lib\ws.api_1.1.0.0.jar lib\org.eclipse.persistence_1.1.0.0_2-1.jar
In the Edit Deployment Profile Properties, select Include Manifest File, specify the main class to execute, and Add the classpath file to be included in the manifest.
Deploy the jar file.
In a deployment area, create the directory that will contain all the classpath jars (e.g. ./lib).
Within the directory ./lib, extract all files from wseeclient.zip (found in {weblogic home}/server/lib)
Copy wlfullclient.jar into the directory ./lib from the {weblogic home}/server/lib
Copy ws.api_1.1.0.0.jar into the directory ./lib from {oracle middleware home}modules
Copy org.eclipse.persistence_1.1.0.0_2-1.jar (for jaxb support) itno the directory ./lib from {oracle middleware home}/modules
Copy the deployed client jar to the deployment area and execute, e.g.:
java -jar ClientTest.jar myArguments

How to create a JMS standalone client with SAS PE8.2 ?

HI everyone,
I use Creator2.1 and I want to write a JMS standalone client that communicate through JMS with a webapp built with Creator.
My pb is that I dont know how to set up initialContext.
Hashtable env=new Hashtable();
env.put(Context.PROVIDER_URL, "mq://localhost:28676/jms");
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.enterprise.naming.SerialInitContextFactory");
context = new InitialContext(env);
factory = (TopicConnectionFactory) context.lookup(factoryName);
For example this code doesnt work and I have the following exception when I try to run my client.

Please refer to http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6377822, particularly the evaluation. Could your situation be the same too (i.e server ip address changing dynamically)? Also, which OS are you using and do you have any firewalls setup that prevents access to port 3700?

Classpath for JMS standalone client

Hi,
I observed some problem, when I try to start my JMS client application. If in classpath is oc4j.jar it works, but when I replace oc4j.jar with oc4jclient.jar doesn't
I notice the message:
Exception in thread "main" java.lang.NoClassDefFoundError: com/evermind/server/jms/EvermindXAConnectionFactory
at com.evermind.server.jms.ConnectInfo.getPass(ConnectInfo.java:98)
at com.evermind.server.jms.EvermindTopicConnectionFactory.createTopicCon
nection(EvermindTopicConnectionFactory.java:83)
at sapconnector.MaterialMoverClient.main(MaterialMoverClient.java:52)
the line no. 52 exactly means:
TopicConnection connection = factory.createTopicConnection();
What the OC4J client jar (oc4jclient.jar) is not enough for starting JMS standalone client?
regards
Krzysztof

Hi, thanks for the reply.
Well, I figured out that problem. It was my jar file. One of the jar file, which is imqjmsra.jar wasn't really the right one and that was giving me the problem. Well, at least that is working not, but I am having new problems.
Right, I have been trying to make this work for about three days now. The truth is that my standalone JMS does work, when it is running on the same machine where the J2EE Server is located, but I am trying to make my JMS standalone client to connect to J2EE server from different location. Now I am getting connection refused error. Well, I guess I will be keep trying util I get this working.

Getting Sun ONE Initial Context from standalone client

Hi,
I'm having problems connecting to Sun One's JNDI from a standalone client ... I've seen other topics raised with similar problems but with no real answers.
I can connect to what i think is a different JNDI resource with:
Hashtable env = new Hashtable();
env.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,           "com.sun.jndi.cosnaming.CNCtxFactory");
env.put("java.naming.provider.url", "iiop://localhost:3700");
jndiContext = new InitialContext(env);
But this JNDI does not hold my JMS resources (connection factories, queues, etc) ??? Am i connecting to the wrong port??
I've tried to look at the documentation but with no success.
Any ideas?
cheers,
Chico.

How can I deploy a simple stateless ssion EJB and call it from a standalone client

Hi,
I'm creating s simple staless session EJB that has a method that takes a name and prints "Hello" + name. This EJB is in a package called "com.demos.mydemo.ejbs.hello"
How can I deploy this to OC4J?
How can I call it from a standalone client(no JSP, no servlets)?
In Sun's J2EE is very easy to deploy and I don't have to know any XML stuff.

When I run the client I'm getting the following error: Caught an exception.
javax.naming.CommunicationException: Can't find SerialContextProvider

This makes me think that the client can't see the deployed EJB on the OC4J.
How can I fix this problem?

Nabil -
Your standalone client needs to obtain certain server-dependent properties. You can provide them in your code or grab them via a properties file.
For Orion - you need essentially the following setup, filling in your own information...
Define your standalone client class with "main" etc (this is orion specific - should work for 9i AS as well - perhaps there are some differences)
public class SomeClass {
try {
Properties p = new Properties();
p.setProperty("java.naming.factory.initial",
"com.evermind.server.ApplicationClientInitialContextFactory");
p.setProperty("java.naming.security.principal","server_admin_name");
p.setProperty("java.naming.security.credentials","server_password");
// THEN you can get your intitial context reference
InitialContext initial = new InitialContext (p);...........
Then go about your business.....
A good book to get is called "Professional Java Server Programming J2EE Edition" - there happens to be a reasonable amount of Orion/OCJ4 centric information since one of the authors is Karl Avedal - one of the principals behind Orion. Go out to java.sun.com and look at some of the J2EE tutorials - unfortunately a lot of it is hidden behind the J2EE Deployer, but you will get a good sense of what goes into outside-the-container standalone clients.

How can I set Response Queue for standalone client using JMS Jax-RPC ?

Hi,
I am developing a standalone client for a web service running on a Weblogic 10.3 server using JMS transport. The response seems to be placed in JMSServer!JMSServer.TemporaryQueue0 when I try to test the application.

Running JMS client on multiple systems (using J2EE 1.4)

Hello all,
Can anyone tell me if it is possible to run a JMS client on a system that is not running a J2EE server on localhost? Is there any way to reference the server on another machine (using J2EE 1.4 server)??
I found information in the J2EE 1.3.1 tutorial that tells of ways to
- run the client program with both systems running the server
- run the client program with only one system running the server (which isn't localhost)
However, the corresponding portion of J2EE 1.4 tutorial only specifies running the client with App server running on both systems...... does this mean that we cannot run a standalone client program with no server on localhost in case of the 1.4 server?
Also, most of the tutorials on JMS I have seen so far only explain the scenario with both the client and the server on a single machine. Is this how average JMS applications work?? What I mean to ask is, in a typical scenario where does a JMS client run....?? at the server, or at the client (which may or may not be running a server at localhost).
Thanks for your time.

The functionality has not changed in J2EE 1.4 outside of reving to JMS 1.1

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

How to run a client program in Session bean using weblogic 8.1

Hi
I am new to weblogic server 8.1. I sucessfully deployed session ejb Session Bean. I created sessionbean jar file and put it it classpath also.
and also i created sessiobeanclient jar file, it included in class path.
While running client program it throws exception like noclass def found exception
plz tell me the right way to run the session ejb program.
bye

Hi,
You have to follow the given steps before you are going to run the client program that invokes the session bean .
1)set the Weblogic Environment using the tool setWLSEnv
2)place the Session bean jar file in classpath
3)run the client program
Note:If the client has to execute on remote machine we need to copy client class,remote interface, home interface and other classes which are used as
parameters and return types.

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
Deepika

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.

The question is too vague to be answered. It's a design decision that needs more details.
