Hi Experts:

Need your help on deploying EJB.

Created a simple EJB and I am trying to deploy on weblogic8 and I am getting the following errors.
___________________________________________________________________________
<Error> <Deployer> <BEA-149027> <Unable to activate application, TestEar, from source, C:\Documents and Settings\Praveen\workspace\TestEar. Reason: weblogic.management.DeploymentException: Error while loading descriptors: Error processing file ‘META-INF/application.xml’. weblogic.xml.process.XMLProcessingException: XML document does not appear to contain a properly formed DOCTYPE header – with nested exception:
[weblogic.xml.process.ProcessorFactoryException: XML document does not appear to contain a properly formed DOCTYPE header] – with nested exception:
[weblogic.xml.process.ProcessorFactoryException: XML document does not appear to contain a properly formed DOCTYPE header]>

Any suggestion is greatly appreciated.

Thanks,
Praveen.

Praveen,
It looks like your application.xml file is invalid… can you copy-paste it here for us to see?

[PKKALLA]

Riyad.

Here is the content from application.xml

I don’t see Home, LocalHome, remoteInterface etc.
I would like to create EJB 2.0 classes. How do I do it.

Thanks a lot for all your help.

Praveen.

Praveen,
I think the issue is that you are trying to deploy a J2EE 1.4 application to WebLogic 8 which IIRC only support J2EE 1.3. You need to upgrade to WebLogic 9 for J2EE 1.4 support or you need to re-create your project and be sure to specify the J2EE 1.3 specification when creating it.

[PKKALLA]

Riyad:

I created recreated the project with J2EE 1.3 but it just created Approvers.java it didn’t create ApproversHome.java, ApproversLocalHome.java and ApproversLocal.java and ApproversBean.java.

Do I have to chnage something in the IDE to generate these files?

Thanks for you valuable suggestions.

Praveen.

[PKKALLA]

Riyad:

I am still getting the same error.

Here is what I did.

From the file menu selected New –> Project
In the wizard window selected “EJB Project”
Then gave BLProject and selected “Specification Level” as J2EE 1.3
and hit finish.

Then on the src project, from the context selected “New” –> “Session Bean”.
Typed Approvers in the name field and selected “both” in the “select the access for EJB”.

Am I don’t anything wrong?

Thanks,
Praveen.

Yes, you need to use XDoclet to generate the rest of those files as outlined in our EJB tutorial here:
http://www.myeclipseide.com/images/tutorials/quickstarts/firstejb/

Riyad:

i am getting following error when i ran xDoclet.

[Riyad Kalla]

Praveen,
The error seems fairly straight forward. Did you set the doclet version to 8.1 or 9? If so, check your EJB XDoclet tags and see if you have set “createtables” argument anywhere to a value other than the ones listed:

(Disabled|CreateOnly|DropAndCreate|DropAndCreateAlways|AlterOrCreate)

[PKKALLA]

Riyad:

My bad.

I think this is the best support I every got.

Thanks a lot.

Praveen.

[Riyad Kalla]

Praveen, thank you for the kind words. I’m glad it helped.

[PKKALLA]

Sorry Riyad,
When I run xDoclet I am getting the following

java.lang.UnsupportedClassVersionError: xjavadoc/ant/XJavadocTask (Unsupported major.minor version 49.0)

Thanks for your time

Praveen.

[PKKALLA]

Please ignore my previous request. changing JDK to point to JDK 1.4.2 worked.

How ever I have a small problem and hoping you could help.
I deployed the ear file on weblogic 8.1
and in my JSP I have the following code

HelloWorldLocalHome localHome = (HelloWorldLocalHome)HelloWorldUtil.getLocalHome();

I am getting the following error when I run the JSP

I checked welogic server. I checked for weblogic I couldn’t find comp/env/ejb/HelloWorldLocal in the JNDI tree.

Thanks,
Praveen

[Riyad Kalla]

Praveen,
I’m sorry, I don’t know enough about WebLogic to know what it’s doing there exactly.

Did you try googling for similar phrases like “NameNotFoundException: While trying to look up”?

[PKKALLA]

I am having problems deploying EJB.

When I select EJB project and click on deploy Icon and click on Add I don’t see weblogic server but if I can see weblogic server for war and ear projects.

Thanks for all your help.

Praveen.
