public class: SetClassLoaderHandler [javadoc | source]

java.lang.Object
   org.apache.axis.handlers.BasicHandler
      org.jboss.net.axis.ResetClassLoaderHandler
         org.jboss.net.axis.SetClassLoaderHandler

This handler is to embed an incoming request into the right classloader and should be put into a request chain after the service detection handlers. It should be complemented by a seperate org.jboss.net.axis.ResetClassLoaderHandler in the response chain to reinstall the thread association in case of success.
