ClassCastException using Moduleprocessor

[Former Member]

Hi, all!

I' ve got a problem with Moduleprocessor for XI:

1. I created a stateless Session-EJB (remote & local interface) in NWDS which implements the com.sap.aii.af.mp.module.Module interface and added an empty process()-Method.

2. I then built an EJB Jar-Archive.

3. Afterwardss I created an Enterprise Application and added my EJB Module to it.

4. I finally built an Application Archive and deployed it to the J2EE-server via NWDS SDM.

5. A collegue of mine added the Beans JNDI-name to the Mail-Adapter of the XI.

6. When sending a mail, a ClassCastException is thrown:

error occured: [2006-01-17T07:18:38Z] 2 new messages found among 35 messages in total; processing message 34exception caught during processing mail message [34]com.sap.aii.af.mp.processor.ModuleProcessorException: Processing Error caused by: java.lang.ClassCastException; processing message 35exception caught during processing mail message [35]com.sap.aii.af.mp.processor.ModuleProcessorException: Processing Error caused by: java.lang.ClassCastException; action[s] taken

Could anybody help me with that matter?

Thanks a lot in advance!

Hi,

Did you Refer the module jar or Included them (if you have included then it gets in your ear file, so it gets an error as class loaders are different).

You need to refer the module jars.

Hi!

To be honest: I' m a newbie and don' t really know whether I included or referred to the jar. What I did is creating an Enterprise Project and then - from the context menu of 'application.xml' - said 'Add Module' choosing the newly created EJB Project.

Am I missing something?

Hi,

In NDS , use File -->New -->Enterprise application project, then add project name, then click NEXT And Not Finish,

You get the screen Referenced Projects, choose and refer HERE, by clicking on the check box.Then select finish.

Did you do like this? Just give it a try.

Hi,

On the previous message you wrote that you "added from context of the application.xml"

Donot ADD Module like that,

Refer it while you create it as i said above.

This might be a bit confusing, but please again ensure you did not add from context of application.xml

Meanwhile i am looking at my own modules and thinking what else can be the reason.

Anirban.

Open the created EAR file with WinZip und check, if the library jars are included. If this is the case, then delete it. Only the jar file of your application is allowed.

Hi, Stefan!

Thanks for your answer! If I do so, the following Exception is thrown while deployment:

Hi, Anirban!

I did like you told me, but unfortunatly it still doesn't work. Are probably any settings in the deployment descriptor(s) necessary?

Once again thank you very much for your kind efforts!

Hi,

My last shot at your issues,

1.Donot change anything as of now as you are not sure of the issues that may come.

2.Logon to https://websmp106.sap-ag.de/nw-howtoguides

3.Download HowToCreateAdapterModules.pdf

Sounds a bit elaborate but please do it as i reached myself in module devlopement by this.

4.Follow step by step(create a new project for this) and i am sure you will hit success.

It was nice talking to you and you have a great virtue of patience, keep it up.

Bye,

Anirban.

Hi Thomas,

Check ejb-jar.xml file, whether you have included correct references or not.I mean instead of refering your interfaces give references on Server and remove the jar files(only those for which you have given reference in application-j2ee-engine.xml) from your .Ear project.

In ejb-jar.xml reference to interfaces should look like this -

<home>com.sap.aii.af.mp.module.ModuleHome</home>

<remote>com.sap.aii.af.mp.module.ModuleRemote</remote>

<local-home>com.sap.aii.af.mp.module.ModuleLocalHome</local-home>

<local>com.sap.aii.af.mp.module.ModuleLocal</local>

I hope it will solve your problem(not sure).Previously i also got this error and got solved when change ejb-jar.xml.

Hi Thomas,

I think the problem is in your code of process method().

The process() should return an object type ModuleData.So the syntax should be like this

public ModuleData process(

ModuleContext moduleContext,

ModuleData inputModuleData)

throws ModuleException{

//Write your code here.

return inputModuleData;

}

If it is same like above, then the problem will be in the code you have written in process();

Hi, Gowtham!

I implemented the process-Method without additional code except the return inputModuleData-statement and it threw the Exception.

Are there any additional settings to be made in the deployment descriptors or adaptions in the Home/Remote/LocalHome/Locale-Interfaces?

Regards,

Thomas

Hi Thomas,

most probably the JNDI-name is not correct

check service JNDI in the visual Admin to see

if such a JNDI-name exits

Hi, Michal!

Thanks for answering.

I copied the JNDI-name out of Visual Admin and pasted it into the integration builder (prefixed with 'localejbs').

Thomas
