Axis2's wsdl2java fails on RPC/Encoded style web services

There are only 3 options that I have found that can be used in Java for old-style rpc/encoded web services:

1) SUN's reference implementation of JAX-RPC (wscompile)

2) WebLogic's clientgen (I used 8.1 version)

3) Axis1 v1.4 wsdl2java

Originally we used Axis 1.4 for that and it showed quite poor performance on relatively large service responses (>20k) i.e. client processing time increased more than twice comparing to plain HTTP request without parsing. And the time grows if response gets bigger. It took more than 30s to just deserialize 1MB large respose.

SUN's generated client didn't really work and it failed on request with the message:

unexpected element name: 
   expected=getSubscriberInfoReturn, 
   actual={ws.generated.api}getSubscriberInfoReturn

I have tried using WebLogic's 8.1 clientgen, and compared client code to Axis 1.4 generated client's performance. And Axis won the race. So, even though Axis client is performing not that good on relatively large responses it still is the best option out there for old rpc/encoded web services :(.

RPC encoding is not supported on Axis2. Source: http://wiki.apache.org/ws/StackComparison

Try Axis 1, I've used it for this exact reason.
