[Springframework-developer] LinkageError using Axis/SOAP client

[Darren D. <da...@da...>]

This is more likely to be a server error, but just in case..

I have an application accessing a couple of webservices via 
org.springframework.remoting.jaxrpc.JaxRpcPortProxyFactoryBean and 
org.apache.axis.client.ServiceFactory as the serviceFactoryClass.

This works fine unless the application is restarted.  After a restart, 
any attempt to use the webservice results in the following stacktrace. 
Any subsequent attempt to access it after this error results in a server 
crash.  If the server is restarted the problem doesn't occur.

Running on WebSphere 5.0.2

Anyone seen this kind of behaviour before?
