Thanks Kimura. I was contemplating to file a bug on this, but wanted to confirm with
the group first. Now that the thing is
filed can we push anyone to fix it? I think the fix you proposed should solve the
problem.
I have one more question abt pivot handler. I tried to replace pivot handler(provider)
with jax-rpc handler but it fails.. it
gives me an error at
-->
org.apache.axis.deployment.wsdd.providers.WSDDHandlerProvider.newProviderInstance(WSDDHandlerProvider.java:91)
because it has the following check
if (!(Handler.class.isAssignableFrom(_class))) {
throw new ConfigurationException(Messages.getMessage("badHandlerClass00",
_class.getName()));
}
This makes it clear that the pivot handler should implement axis handler interface. I
couldn't find anything specific abt pivot
handler in jax-rpc spec. Only that it says request handler chain is invoked before
dispatching RPC request to target service
endpoint implementation. Does the pivot handler fall into the JAX-RPC runtime
system(AXIS) specific implemenation to dispatch
the RPC call and doesn't need to follow the jax-rpc handler interface??
