EJB Deployment in WebLogic 8.1 very very urgent

Hi
In order deploy EJB application in Weblogic 8.1, is it necessary to compile
the application in WebLogic.ejbc. I did not find such files in WebLogic 8.1
In weblogic 7.0 versiion has such files.
The present procedure is as follows.
1. Create a jar file contains all class files.
2. Create a jar file contains class jar files, plus .xml files
3. Deploy into weblogic 8.1 server EJB Deployment utility.
==================
Please help me.

They are reccomended because the next step going from your simple single EJB
to anything interesting, like adding more EJB's adding web-apps, adding
web-services etc etc involves ears. If the setup and overhead for an EAR is
easy, then just start there.
But no if you just doing helloworld you of course dont have to ears.

You can still run ejbc from the command line its still there. And you
can
still run weblogic.Deployer. (I dont ever reccomend jaring up in dev,
it
just takes longer, do exploded its easier and faster).
But ear's are easy, see:So ears are recommended even if you're just doing EJBs (e.g., a simpleHello World)
and no web apps (none needed for the Hello World or a PC client)?

My understanding is ejbc has been deprecated and replaced with appc.Moreover,
BEA is encourgaging developers to deploy ear files. All I want todo is
to use
ant to deploy a jar file with a single EJB in it. I'm not findingthe WL
documentation
very helpful. Hopefully, you'll have better luck than I.

Calling EJB deployed on Weblogic 10.3 from WebSphere Application Server 6

Hi,
We are trying to call an EJB(2.1) deployed in Weblogic 10.3 from WebSphere Application Server 6.
The problem is that the jars containing Weblogic's initial context factory are compiled with JDK5. (Client jar was built as per [http://download.oracle.com/docs/cd/E15051_01/wls/docs103/client/jarbuilder.html] .)
WebSphere is still running on JDK1.4.
Therefore when trying to get the InitialContext to lookup up the bean we get major/minor version errors because of the compiler level mismatch.
Has anyone faced a scenario like this and come up with a solution?
Are there 1.4 jars for Weblogic 10.3 out there?
Any help?
Thanks

Hi Dan,
Yes I am using EJB 3. I saw this thread earlier also but :
1. In my case I am not calling the EJB 3.0 methods directly. I am using a java client (Cataloged as a Java Class Library) which does the lookup and calls the EJB methods. (I am not cataloging and calling the EJB 3.0 methods directly).
2. It is working perfectly fine when the EJB is deployed in Weblogic 10.0 or 10.2.
I am very much new to this so please bear with my small and silly questions! Thanks a lot for you help !
Cheers !

EJB deployment in weblogic 8.1

I am new to EJB's. I have truly tried to research and solve this problem. I am trying to deploy a simple EJB in wls 8.1.
Here are snippets of ejb-jar.xml, web.xml, and weblogic-ejb-jar.xml:
ejb-jar.xml:
<ejb-jar>

<remote>com.myCo.util.UserScanSystemsRemote</remote>
<ejb-link>com.myCo.util.UserScanSystems</ejb-link>
</ejb-ref>
When I deploy I receive an error message that the ejb-link com.myCo.util.UserScanSystems could not be resolved. com.myCo.util.UserScanSystems is both the ejb-name in ejb-jar.xml and weblogic-ejb-jar.xml and the jndi-name in weblogic-ejb-jar.xml. I have tried another [unique] name for ejb-name but still receive the same problem. I am primarily deploying into an exploded webapp but have also tried deploying ear and war files using >../ejb/ejb.jar#com.myCo.util.UserScanSystems as a relative path to the jar containing the EJB but same type of error.
what is the ejb-link supposed to be? the jndi-name in weblogic-ejb-jar.xml ? (In my case it's both jndi and ejb-name)
What am I missing?
Exception:weblogic.management.ApplicationException: activate failed for dts Module: dts Error: weblogic.management.DeploymentException: Could not setup environment - with nested exception: [weblogic.deployment.EnvironmentException: [J2EE:160101]Error: The ejb-link 'com.myCo.util.UserScanSystems' declared in the ejb-ref or ejb-local-ref 'ejb/UserScanSystems' in the application module 'dts' could not be resolved.

Note that once the exploded version of application fails I can goto the weblogic console and deploy the EJB using the jar file that gets approot/ejb/ejb.jar but subsequnt deploy attempts at the application still fail.
If anyone has a working example and could post ejb-jar.xml, pertaining piece of web.xml, and weblogic-ejb-jar.xml that would be GREAT!

Refer to the ejb-link section in the ejb-local-ref.

I've searched the forum for similar problems and the solution was to include the wlfullclient.jar in client classpath.
I've done that already however the problem persists. (maybe it's necessary to configure some IIOP parameters)
Anyone have any clue for this problem?
Thanks in advance.
Regards.

Hi,
include wls-api.jar in your classpath and provide me an update...

Is there some kind of security in ejb?. If so how can do it? Kindly help

Hi,
Some improvement regarding the code. I found i had to use the logincontext to login to the session so i had modified my code like this which for the most part i got from this blog(http://weblogic-wonders.com/weblogic/2010/06/15/jaas-login-in-weblogic-server/)
here's the code....

EJB deployed but doesnt show up in JNDI tree on weblogic

Hi,
I have a sample EJB deployed on weblogic 10.3 server. My Bean class contains following code.
========================================================================
@Stateless (mappedName = "DemoEJB")
@TransactionManagement(TransactionManagementType.BEAN)
public class DemoBean implements SessionBean {
     static final boolean verbose = true;
     private transient SessionContext ctx;
     private transient Properties props;
     @SuppressWarnings("deprecation")
     @Override
     public void setSessionContext(SessionContext ctx) throws EJBException,
               RemoteException {
          // TODO Auto-generated method stub
          if (verbose)
          System.out.println("setSessionContext called");
          this.ctx = ctx;
          props = ctx.getEnvironment();
     public String demoSelect()
throws RemoteException
return("hello world");
===========================================================================
I have created a jar file for the above class using eclipse and deployed it on weblogic. I can see the EJB in the <Deployment> on weblogic but it doesnt appear in <EJB> on JNDI tree view. Therefore i cannot access it from my client code (also written in Eclipse IDE).
I will appreciate any guidance in this regard.
Thanks

EJB communication between weblogic and websphere

Hello:
I have weblogic 7.1 instance running in machine A and websphere running in machine B. I want to make a call to the ejb deployed from weblogic to websphere. Any experience in this would be very helpful. Or pl. post the procedure.
Thx in advance.

I don't think that there is any magic here, although I've never tried it.
All you need is the compiled EJBHome and EJBObject interfaces in the
classpath of the calling EJB, get an InitialContext in the JNDI namespace of
the target EJB container using the name of the JNDI InitialContext Factory,
do a lookup on the bean making sure to do a PortableRemoteObject.narrow when
you are casting the Home stub with the vendor specific version of
PortableRemoteObject(and that may be the real trick), call the appropriate
create method, and you are rolling.
I guess the question becomes how to make sure that when you are calling
PortableRemoteObject.narrow on the Home stub, that you get the vendor
specific version for the EJB container and JNDI namespace from which you are
doing the lookup.
I guess the answer is, I'm guessing. Have you tried it?

Ejb deployment - classloader question

Hi Guys
I have a very basic question regarding EJB deployment in Weblogic 6.1 sp2.
Is it possble to create an EAR file such that -
1>it contains a WAR file [of servlets/jsps/client classes] - A
2>a jar file containing our core server classes[not EJBs] - B
3>a jar file containing EJBs - C
here A and C are definitely getting loaded by different class loaders - I want
the classloader for B to be parent of the classloaders for A and C - so that both
A and C can see B. - is this possible by some EAR/Weblogic specific way.
OR
the best solution is to place the B in the main classpath and deploy the C and
A in an EAR?
thanks

A and C can see B. - is this possible by some EAR/Weblogic specific way.Made possible by placing B in the ear at the root level and referring to B with the
Class-Path manifest directive in the ejb jar file for C. This will put B in the ejb
classloader's classpath making it visible to C and to A since the classloader for C
is the parent of the classloader for A. Which, is the recommended way.

A in an EAR?
This works, but the classfiles in B are now static for the uptime of the server. If
you want to make changes in B, you must restart the server. If you configure it the
way described above, you can reload the B classes by redeploying the application ear.

EJB Deployment error in Weblogic 8.1 very urgent

Hi
Mark I forgot to send my error message. So I am sending again.
Sorry for the trouble.
Murali
[weblogicerr1.txt]

They are reccomended because the next step going from your simple single EJB
to anything interesting, like adding more EJB's adding web-apps, adding
web-services etc etc involves ears. If the setup and overhead for an EAR is
easy, then just start there.
But no if you just doing helloworld you of course dont have to ears.

My understanding is ejbc has been deprecated and replaced with appc.Moreover,
BEA is encourgaging developers to deploy ear files. All I want todo is
to use
ant to deploy a jar file with a single EJB in it. I'm not findingthe WL
documentation
very helpful. Hopefully, you'll have better luck than I.

Deploying EJB in Weblogic 8.1 very very urgent

Hi
I had followed the logic Mr Mark has told me. But it did not work. Please
the attached files.
1. I had copied all of my class files into META-INF directory.
my SampleObject.jar file contains as follows.
jar -tvf SampleObject.jar gives
.META-INF
.Sample.class, SampleHome.class, SampleBean.class, SampleClient.class and
ejb-jar.xml,
weblogic-ejb-jar.xml files.
I did not package my class files. instead i had deployed it in META-INF.
Further I made one more attempt as follows.
My server is called myserver.
so I copied all of my class files, SampleObject.jar files into the following
directory.
C:\bea\user_projects\domains\mydomain\myserver\upload directory. This is the
directory
where weblogic copies the SampleObject.jar files.
It did not work at all.
Please help me.
I am failing for the past five days . Treat this as very urgent.
Thanks in advance.

Murali:
I suggest you start with something simple that works. And then go from
there, modifing it one bit at a time and ensuring that it still works. Your
jar tf output is all munched up so it is hard to follow. I suggest you
start with
$WL_HOME/samples/server/examples/src/examples/splitdir/helloWorldEar/
See how it builds the ear and the ejb jars and go from there.
You can do:
ant ear
and
examine the contents from there.
Alternatively you can use Workshop to build an EJB as well.
PS. Your classes dont go into META-INF. But rather than go through the
entire exercise of getting your app working I suggest as noted above you
start from a known and modify.
cheers

Check out the beanManaged example that ships with WLS and read the accompanying docs. This

Memory leak in a client using EJBs deployed in a Bea Weblogic 10.0.0 cluste

Hi all,
We are having a memory leak in a client using stateless EJBs deployed in cluster. The client is a Tomcat 6.0.18 with java 6 but it is reproduced using Tomcat 5 with java 5. The client is calling a Weblogic Server 10.0 making
calls to an EJB deployed in cluster that has two instances installed in two different machines.
The client works fine if we shutdown one of the server instances and so when the client is using only one instance.
Resuming the environment:
Client Side:
1 HP-Itanium machine with HP-UX.
1 Tomcat 6 with java 6 (reproduced with java 5)
Bea Weblogic client (wlclient.jar) for Weblogic 10.0.0
Server Side:
2 HP-Itanium machines with HP-UX
Bea Weblogic Server 10.0.0 installed in both machines
An unique domain
Two Bea instances (one per machines) associated to a Bea Cluster
EJBs deployed in both instances
We have monitored the memory consumed in Tomcat and we have noticed that the VM memory PS OLD GEN grows up permanently when we make tests having the two server side Bea Instances up. We have extended
the memory VM parameters in Tomcat client till 1G and it's only a way to delay the end: the free memory is empty, the GC is not able to free no more byte and the CPU is 100% consumed by the GC work. At the end Tomcat Client
doesn't accept more http petitions and must be restarted.
Besides, we have studied the VM memory in Tomcat using jmap and importing it using Eclipse Memory Analyzer. We have seen some strange memory blocks of several Mbytes that are always growing up and that are stored
under data structures in the package com.sun.corba:
com.sun.corba.se.impl.legacy.connection.SocketFactoryConnectionImpl (4.5Mb)
|
-> com.sun.corba.se.impl.transport.CorbaResponseWaitingRoomImpl

Why not search http://bea.com and see what pops up. I searched their site for "EJB deployment descriptors" and got quite a few hits.
