CXF and JDK 1.6 compatibility
Hi
I have some question/thoughts about using CXF with JDK 1.6.
As I understand the core module of CXF was written, officially tested
against and should be used with Java5.
There were some discussions on mailing list, if it is possible or not to
use Java6 as runtime:
“The next milestone release” Feb 21, 2007
“Java 6 failures” Jan 22, 2007
The main problems which were there described are (content from the
discussion):
- The versions of STAX, JAXB, JAX-WS, etc... that are required/used by
CXF are not compatible with the ones in 1.6. (as I understand in 1.6
there are older)
- The parser (XML) and such (validator) is different. Some of our (CXF
developers) tests are failing with JDK 1.6.
Actually I’m using CXF 2.0-RC with JDK 1.6 and till now I didn’t have
any problems.
What I have tried:
- Java6 and all jars from CXF distribution
- Java6 and jars from CXF distribution without: STAX, JAXB, JAX-WS jars
(I removed: jaxb-api-2.0.jar, jaxb-impl-2.0.5.jar, jaxb-xjc-2.0.jar,
jaxws-api-2.0.jar, stax-api-1.0.1.jar, stax-utils-20060502.jar,
wstx-asl-3.2.1.jar)
I did not use /lib/endorsed dir mechanism so in first try there were
some kind of mix: some classes of eg. JAXB were taken from JAXB jars
while others from JDK 1.6 runtime.
In both, communication client server and creating services from WSDL
file was successful.
My questions are:
1) I wonder if there are some parts which I can double check – any hints
how to get error situation?
2) Are there the results of your tests against Java6 available somewhere?
3) Do you have any plans/schedule referring to the CXF and Java6?

Hi Daniel,

I also tried having the jaxb-api2.2.3.jar under the jre/lib/endorsed dir and
still getting the same error as above. Please let me know if there are any
solutions.. I have been stucked here for a while.
Cheers
Eesan.

Thanks for the explanation, I was a little bit confused why is it working.

Krystian,
Those emails about Java6 issues were back when we were targetting JAX-WS
2.1 and JAXB 2.1. Since then, we backed down to JAX-WS 2.0 and JAXB
2.0 so most of the problems aren't problems right now. That said, now
that we have shipped a JAX-WS 2.0 compliant version, we plan to restart
the 2.1 work very shortly and the problems will pop up again.
The main issues were around the JAXB api and JAXWS api jars. The
java.xml.ws and java.xml.bind packages in the Java 6 rt.jar are the 2.0
versions. Thus, they work fine for CXF right now since we just need
the 2.0 versions. However, when we move to 2.1, we'll need the 2.1
versions to be put into the endorsed dir so that they will be picked up
instead of the 2.0 versions built into the JDK.
That said, we do have some unit test failures with Java 6 that I started
trying to fix at one point, just haven't had time to finish it. Those
are mostly around the XML parsers/stax impl providing extra stuff we
don't expect in the prologue. (standalone="false")
Oh, one more note... At the time, maven 2.0.3 or 2.0.4 was the latest
version and that version had issues with Java 6. We're up to 2.0.5
which fixes those.
