Re: [Dev] ESB proxy service for mix of TwoChannel and InOnly operations

2015-12-11 Thread Ayoma Wijethunga 
Hi Jagath,

It was only a test service and I have attached class with this. Full source
is available at [1] as well.

Problem occurs with "void confirmOrder(-)" method because it is an InOnly
operation.  Unless "OUT_ONLY" property is applied on endpoint, ESB tries to
get return value of above operation invocation, resulting in the exception.

Hence, wanted to check with team what is the best approach to follow while
defining proxy for a WSDL that has both InOnly and TwoChannel operations in
a mix.

Thanks and best regards,
Ayoma.

[Dev] ESB proxy service for mix of TwoChannel and InOnly operations

2015-12-10 Thread Ayoma Wijethunga 
Hi All,

This is relevant to WSO2 ESB 4.9.0.

In WSDL attached [1
],
there are five TwoChannelAxisOperation(s) and one InOnlyAxisOperation. In
such situation, if we create a single proxy service in ESB with
configuration [2
],
InOnlyAxisOperation will fail with below exception :

ERROR - NativeWorkerPool Uncaught exception
> java.lang.UnsupportedOperationException: An access occurred that is not
> valid.
> at
> org.apache.axis2.description.InOnlyAxisOperation.getMessage(InOnlyAxisOperation.java:117)
> .
>

​​It was observed that it is possible to use "OUT_ONLY" and
"FORCE_SC_ACCEPTED" to correct this [3
]
[4
].
But relevant transport property applies to endpoint, resulting in
TwoChannelAxisOperation to fail if applied.

When creating proxy service for a web service, what is the best practice to
follow in order to avoid this type of problems?
Do we create,

   - separate proxy services for each set of operations
   - use "switch" or "filter" mediator in the "in sequence" and "send" to
   OUT_ONLY endpoint depending on operation

or what is the best path to follow?
