[kepler-users] Timeout in Kepler using a simple webservice

[christopher tuot]

Hi Luis,

I have debugged a nightly build (current version) from Kepler in Eclipse.

The problem occurs in the class:

org.sdm.spa.WebService (CVS Base revision 1.53)

At line: 847

Object invokeResult = _call.invoke(_objArr);

I added the following annotation to the adder.java class:

@SOAPBinding(style = SOAPBinding.Style.RPC, use=SOAPBinding.Use.ENCODED)

Now Kepler gets the answer but I have to set the timeout really high
(600000), if not I get:

java.net.SocketTimeoutException: Read timed out

Our webservice is answering almost instantly so I do not understand what
is happening there!?

Any other hints to get us back on track?

Many thanks in advance and regards,

Christopher Tuot
