JRA connector in NetWeaver 7.3 : java.lang.NoClassDefFoundError: javax/resource/cci/Connection

[former_member201460]

Hi,

I'm trying to deploy a project very similar to the one described at http://scn.sap.com/community/open-source/blog/2012/05/01/nw-73-spring-31-jsf-20-primefaces-part-1 and http://scn.sap.com/community/open-source/blog/2012/05/02/nw-73-spring-31-jsf-20-and-primefaces-part-....

The idea is use a JRA configured connector to get BAPI access to SAP data.

Unfortunately, when trying to deploy the application I get the error below:

Warning occurred on server 4392650 during startApp of test.com/disti~portal : com.sap.ASJ.web.000607 (Failed in component: test.com/disti~portal, ) Initialization of servlet [mvc-dispatcher] failed. Check init() method of servlet. Error is: [org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jraManagerBean': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.test.disti.dao.CustomerDAO com.arm.disti.ejb.JraManagerBean.dao; nested exception is java.lang.NoClassDefFoundError: javax/resource/cci/Connection]

The application application-j2ee-engine.xml is described below. I guess I'm missing some runtime reference to those classes ? At compile time, I'm using a connector.jar library I found at NWDS locally (If I try to deploy this jar with my project I get java.lang.ClassCastException: class com.sap.mw.jco.jra.JRA$ConnectionFactoryImpl:sap.com/tc~sapjra~temp@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@6e4715da@alive incompatible with interface javax.resource.cci.ConnectionFactory:library:keytree.co.uk~ec~java~disti~portal~libs@com.sap.engine.boot.loader.ResourceMultiParentClassLoader@6e57e2bc@alive)

I have searched in this forum for days (and also in the internet) but no solution... The only thing I found is that the DC level, there is a connector package (see image), but I cannot successfully reference it.

Anyone can help please ?

Thanks !

Hi,

Solved that. Together with the application ear I'm also deploying a heavy library ear package which I'm referencing from my application. This due to issues with class loading and Spring+Jersey libraries.

The problem was that at this heavy library ear package was missing the runtime references. So I have added them as described below.

Cheers,

Alan

File server/provider.xml in heavy resource loader package at  http://scn.sap.com/community/open-source/blog/2012/05/02/nw-73-spring-31-jsf-20-and-primefaces-part-...
