This demonstrates a regression: WS-MTOM-streaming worked in Apache CXF 2.3.1, no longer works in 2.6.0.

This demonstrates a regression in MTOM streaming in Apache CXF, recently fixed.

What you run

You run demo.mtom.streamsending.client.Driver as a JUnit 4 test.

This test combines a JAX-WS client and server. It starts the server in the background, the test exercises the client.

The following instructions assume you use Eclipse to do so, though that is not really essential.

You can run this in three configurations. Common in all configurations is the use of JDK 6. Personally, I used this precise version:

$ java -version
java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.1) (ArchLinux-6.b24_1.11.1-3-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

Plain JDK 6 configuration

  • (Remove cxf-manifest.jar from .classpath if there.)
  • run demo.mtom.streamsending.client.Driver as a JUnit test.

This uses the reference implementation (RI) that's part of JDK 6. The RI does not do streaming. So expected outcome: testTwoAttachmentsRequiringStreaming fails (the other three pass).

CXF version 2.3.1

  • Unpack apache-cxf-2.3.1 binary distribution,
  • add apache-cxf-2.3.1/lib/cxf-manifest.jar to the classpath,
  • run demo.mtom.streamsending.client.Driver as a JUnit test.

CXF knows how to do streaming.

Expected outcome and outcome seen by me: All tests pass.

CXF version 2.6.0

  • Unpack apache-cxf-2.6.0 binary distribution
  • add apache-cxf-2.6.0/lib/cxf-manifest.jar to the classpath,
  • run demo.mtom.streamsending.client.Driver as a JUnit test.

Exected outcome: Same as 2.3.1.

Outcome seen: Same as plain JDK 6.

This is a regression, CXF 2.6.0 no longer does MTOM streaming properly.

CXF version 2.6.1

(Apache fixes considerably faster than I can find the time to retest! Wow!)

For the record

I generated the WSDL in directory src via

cd src
../../apache-cxf-2.3.1/bin/java2ws -frontend jaxws -wsdl -d WEB-INF -cp ../bin demo.mtom.streamreceiving.server.WSBean

Then, the client stubs were generated with

../../apache-cxf-2.3.1/bin/wsdl2java -p demo.mtom.streamsending.client.stubs -d . -client -validate WEB-INF/WSBeanService.wsdl

I had to remove three WSBeanService constructors that did not compile (at least not with plain JDK), for lack of Service super-constructors.
