迁移Web服务应用程序时的Websphere 8.5 ClassCastException

Question

We are in process of upgrading our appservers and moving all the applications deployed in websphere 5 to websphere 8.5.

We are not able to bring up a webservice application. There is no problem in deploying the ear file, but when tried to deploy( ServiceManagerClient deploy) the webservice, it throws the error

Unsupported response content type "text/html; charset=utf-8", must be: "text/xml". Response was: Error 500: java.lang.ClassCastException: org.apache.soap.server.ServiceManager incompatible with org.apache.soap.server.ServiceManager

I tried all ways I could possibly think of.

First I tried replacing the old soap.jar in the application classpath with the com.ibm.ws.prereq.soap.jar found under /AppServer/plugins

Then I completely removed the soap.jar from the application classpath and put the com.ibm.ws.prereq.soap.jar in /AppServer/lib directory but still got the same error.

I also searched the whole AppServer directory for org.apache.soap.server.ServiceManager class in any of the jars and tried to add the jar in the classpath of the application with no luck.

I am able to deploy the webservice without any issue in WAS 5.5 and Was 7.

I am afraid that I may be missing something completely here and its not just the issue with soap.jar. Any help in pointing me to the right direction would be greatly appreciated.

Answer 1

Apache SOAP support was removed from version 8.0 (soap.jar). Check this link Removed features .

You will need to migrate your web services.
You can check this page for manual migration - Migrating Apache SOAP web services to JAX-RPC web services based on Java EE standards .
Or you can check out WebSphere Application Server Migration Toolkit , which is a free plugin to Eclipse, which could automate some migration of your web services.
