Change Applitacion references

[Former Member]

Hi, I'm trying to change the library references of an application using the the CHANGE_REF command (using TELNET). The library I wan't to remove is the library:webservices_lib but every time I do this it is telling me that the library was removed but when I type the command LIST_REFS It keeps showing in??

Do you know why this happens? Does anybody else have other solution to remove this library from the ClassLoader?

Regards.

Hello Pablo,

library:webservices_lib is one of the resources to which every application receives a default reference when it is deployed. Probably this is the reason for not being able to remove it.

Is there some special reason that you want to remove this reference?

Best Regards

Ok, thanks. I want to remove this reference because I want to put the implementation of the jaxrpc-impl.jar and if this library:webservices_lib is there the .jar is never found it keeps telling me:

java.lang.ClassNotFoundException: com.sun.xml.rpc.client.ServiceFactoryImpl

I've already store jaxrpc-impl.jar in a library and make a reference from my project to this new library, but it is not using the jars that are in this library.

Any suggestion?

Regards.

Hi Pablo,

Are there any details about the problem in the default traces? Your application should be able to load the classes from the library. Are you sure that you added all jar files (jaxrpc-api.jar) that jaxrpc-impl.jar requires to the library or added a reference from your library to other libraries that have them (library:webservices_lib for example)?

Hi Vyara, this is what I have in the defaultTrace

#1.5#001560ABD22900500000029000001DB000041387C845EEB2#1147373808656#System.err#sap.com/App_STDAts#System.err#ANONIMO_GNAL#2####e6667100e11f11daa68b001560abd229#SAPEngine_Application_Thread[impl:3]_34##0#0#Error##Plain###javax.xml.rpc.ServiceException: java.lang.ClassNotFoundException: com.sun.xml.rpc.client.ServiceFactoryImpl

Loading model: {parent,local,references}

The Jar file jaxrpc-api.jar, which is part of the webservices_lib, only has the interfaces and do not have the implementations. This implementations are not included in the J2EE so I loaded the jaxrpc-impl.jar (with the class com.sun.xml.rpc.client.ServiceFactoryImpl) in other DC library even in the web-inf/lib directory. But it still cannot find the class.

Hi Pablo,

Unfortunately the only thing that I can tell from this stack trace is that the class is in the negative cache as it has not been loaded for some reason. It is a bit strange that the classloader is not that of the application but a common loader. As jaxrpc-impl.jar contains only implementation it definitely requires reference to the interfaces. You should add reference to library:webservices_lib or deploy jaxrpc-api.jar within your library as well.

You can't remove that library
