External Libraries in Custom Adapter Module

[former_member204873]

Hi all,

We developed two custom module. one is PDF creation (itext library) & other is Read Excel (jxl library).PDF file is working fine, it's library got stored on PI server automatically at j2ee/cluster/apps/sap.com/com.sap.xi.repository/app_libraries_container/itext-1.4.2.jar & i added reference for same in application-j2ee-engine file. But for Excel poc the jar file is missing on server.

My EAR file contains:

Manifest.mf

application.xml

EJBExcelModule.jar

jms-resources.xml

application-j2ee-engine.xml

In Channel monitoring, error is coming as:

Error: javax.ejb.TransactionRolledbackLocalException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: jxl/Workbook; nested exception is: javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: jxl/Workbook; nested exception is: javax.ejb.EJBTransactionRolledbackException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: jxl/Workbook; nested exception is: javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: jxl/Workbook.

Please help!

Check the JNDI name of your library and compare the reference in the application-j2ee-engine.xml

[former_member204873]

do u mean jndi name of external library or jndi name of EJB module

[rajasekhar_reddy14]

JNDI name of EJB module

[former_member204873]

how to check references from JNDI name. And do we need to add external jar file in EAR module. I tried to export EAR file, external file was not there in the EAR file. I had added the external library as external library in build path of EJB module.

When you use the external library only in your EJB, then it is eaasier to add the library to the EAR file.

If this is not added automatically, you can add it with winzip or jar command.

Otherwise you create a library project in NWDS. You deploy the library as SDA file. Check the JNDI name of this library with Netweaver Administrator. Use the same name in the deployment descriptor.
