Adapter Module Development (.ear Deployment)

[Former Member]

Hi All,

i Have followed up adapter module development and landed in an error ,

i was said that i should remove of my .jar files and then deploy the .ear file which would make me error free.

But When i delete all those .jar file as shown below

Manifest.mf

Sap_manifest.mf

sda-dd.xml

aii_adapter_xi_svc.jar

aii_af_cci.jar

aii_af_cpa.jar

aii_af_mp.jar

aii_af_ms_api.jar

aii_af_ms_spi.jar

aii_af_trace.jar

aii_util_misc.jar

aii_util_xml.jar

ejb20.jar

*exception.jar*

application-j2ee-engine.xml

application.xml

XFileName_final.jar

it throws an error saying

May 31, 2008 11:35:44 AM /userOut/deploy (com.sap.ide.eclipse.sdm.threading.DeployThreadManager) [Thread[Deploy Thread,5,main]] ERROR:

Hi PI Experts ,

I developed Encryption Module as William Li documents . I face the below issue in communication channel.

Error: java.lang.ClassCastException: class $Proxy3356:sap.com/XMLEncryptionEAR@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@7e2586f1@alive incompatible with interface com.sap.aii.af.lib.mp.module.ModuleLocal:library:com.sap.aii.af.lib@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@1394294@alive

Any help is appreciated on this .

Hi PI Experts ,

Any suggestions or advice .

The class cast exception you get when you don't remove the .jars may be due to the fact that you're using older (or newer) .jars to build your project than the ones actually installed in the J2EE engine where you're deploying the module.

Try to get these .jars directly from the system and probably the class cast exception won't occur anymore (of course, supposing there's nothing wrong with your code itself).

Henrique.

hi,

I have used one module called renaming attachment and i have not removed the library files and still its working fine for me.So its not mandatory to remove the library files.

And if you want to remove the library files then remove only

aii_adapter_xi_svc.jar

aii_af_cci.jar

aii_af_cpa.jar

aii_af_mp.jar

aii_af_ms_api.jar

aii_af_ms_spi.jar

aii_af_trace.jar

these files.

And try to deploy from visual admin instead of SDM.There you can see which classes are missing.

If you are not able to deploy again.Then dont remove the .jar files and deploy again.

If you are using a decentralized adapter engine,then try instead of using that try to deploy it on Integration server.

And let me know what error you are facing.

hope it helps.

Hi Actually,

i deployed using NWDS , i have my .ear file and all othe developments on my local pc (workstation) how could i call those to my PI system which is entirely on other system, should i need to copy those .ear files to the PI system and deploy them

please explain

srini

[former_member187563]

hi,

Yes you have to copy the .ear file to your PI System and then you can deploy using visual admin or SDM.

But its ok to deploy from NWDS.

Did you remove the jar files which i said to remove,are you still getting the same error.

What exception are you getting when you deploy without removing the jar files.

regards.

[Former Member]

hi still same error :

Error: java.lang.ClassCastException: class com.sap.srinifinal.VSriniFileLocalHomeImpl0_0 can not be casted to ModuleLocalHome or SModuleLocalHome

if i remove those .jar files it says in the visual admin that those class has to set in the path , not found.

What couls be the problem, i hope am beatinf around somewhere near , kindly help me out

thx in advance

My Error Description after : clicking on the Message Id:

Attempt to process file failed with java.lang.ClassCastException: class com.sap.aii.af.mp.module.ModuleLocalHomeImpl0_0 can not be casted to ModuleLocalHome or SModuleLocalHome

Srini

[former_member187563]

hi,

i am also facing same problem in one of my modules.

you can try the following things:

1.Dont delete the jar files.

2.I think now you will be doing like:

<ModuleLocal>packagename.classname</ModuleLocal>

but try to use as below

In ejb-jar.xml file, modify Home,Remote,Local,LocalHome entries.

use these entries in respective tags:

com.sap.aii.af.mp.module.ModuleHome

com.sap.aii.af.mp.module.ModuleRemote

com.sap.aii.af.mp.module.ModuleLocalHome

com.sap.aii.af.mp.module.ModuleLocal

3.You need references to connector.jar file which has the classes required at compile time and runtime

Compile time :

From the context menu of the EJB project , follow the path Properties -> Java Build Path -> Libraries.

Click on Add variable and select TSSAP_JAVAX_HOME and click on Extend and select connector.jar from the list displayed.

Run time :

Navigate to the application-j2ee-engine.xml in your EAR project.

Select References on the General tab and click on Add.

Select Select library/interface/service as shown in the snapshot and select j2eeca as in the next snapshot.

4.RESTART YOUR SERVER AFTER DEPLOYMENT.

Hi Ujwal,

Hi After doing all these ,

Now i get below error statement ; am driven by series of Errors
