Description

I declared an operation with an out parameter :

<service name="bugout" provider="java:RPC">
<parameter name="allowedMethods" value="*"/>
<parameter name="wsdlPortType" value="bugout"/>
<parameter name="wsdlTargetNamespace" value="http://bugout/"/>
<parameter name="className" value="test.server.BugOutBindingImpl"/>
<operation name="letsbug">
<parameter mode="OUT" name="outparam"/>
<parameter mode="IN" name="inparam"/>
</operation>
</service>

public void letsbug(ShortHolder outparam, byte inparam)
throws java.rmi.RemoteException

{ outparam.value = 80; }

When I invoke this operation, I got the following exception :

• Tried to invoke method public void test.server.BugOutBindingImpl.letsbug(javax.xml.rpc.holders.ShortHolder,byte) throw
  s java.rmi.RemoteException with arguments java.lang.Byte,javax.xml.rpc.holders.ShortHolder. The arguments do not match
  the signature.

I debugged axis and found that in org.apache.axis.providers.java.RPCProvider.processMessage, the arguments to invokeMethod were :
[Byte : 18, javax.xml.rpc.holders.ShortHolder]

They are not in the right order...
