I have been investigating a JAX-WS webservice client issue for a day now. Its a weird experience where the exception is fired while sending the request to the servcie from the internal ibm class. I could see the connection to the service was successfully established, and the issue occurs while the binary marshalling.
We are in WAS 8.5.X in across all environments. This issue doesn't occur in my local server, but only in the dev environment server. I know I will have to check the IBM jar versions related to JAXB and JAXWS but I will have to prove the issue to the team so that they can look at the jar versions.
Do anyone of you have any clue what happens here?
An Update - This issue occurs only in WAS 8.5.5.1 servers. I have tested with 8.5.5.2 and 8.5.5.0 wintout any issues. I see IBM fix packs addressing unmarshalling issues but nothing about marshalling.

I nailed it. JAX-WS webservice in WAS 8.5.5.1 would not work with out JAXB marshalling fix pack. Hope it should be helpful to someone facing same kinda issue.
