Issue using Apache CXF with MTOM

[shamik]

Hi,

  I'm running a cxf soap webservice in fuse 4.3 . I've configured the endpoint to return a large file leveraging MTOM. The client code is generated using cxf wsdl2java. When the client code it retrieving the file, it encounters out of memory exception. Here's the trace :

As Daniel Kulp from cxf forum pointed out, seems like it's using JAX-WS RI instead of CXF. Could this be the issue ? I'm using spring-dm to define the end-point, while related cxf imports are defined in the pom file.

I've checked etc/jre.properties , JAX-WS API references are being commented out as part of the Fuse distribution. I've checked the deployed bundles, only cxf packages are present.

Any pointer will be highly appreciated.

- Thanks

Hi,

FUSE ESB 4.3 is quite old, could you please test with more recent FUSE ESB version, at least the latest FUSE ESB 4.4.1.x.

If you still see this issue with FUSE ESB 4.4.1.x, please attach your project so that we can take a close look.

Thanks for your reply Freeman. Unfortunately, this is a production environment, switching to a new version is not easily feasible. Just curious, is there any known issue using CXF in fuse 4.3 where it'll use JAX-WS ?

AFAIK, no.

Could you please append a testcase which we can reproduce it? I will take a close look when I get a chance.
