It's related to JDK 6 which ships a version of JAXB impl by itself. Up to JDK 6 Update 3, the JDK ships with JAX-WS 2.0 (which includes JAXB 2.0), but Tuscany requires JAXB 2.1. There are two possible solutions to this problem:

1) Upgrade your JDK to 1.6.0_04 or above, which will include JAX-WS (and JAXB) 2.1 2) Copy the version 2.1 jaxb-api.jar or jaxws-api.jar (you can probably find them in your local maven repo) to <JAVA_HOME>/lib/endorsed to override the API jars that ship with the JDK 3) Use the -Djava.endorsed.dir=<a folder containing our JAXB jars> to override the JAXB from JDK 6.

We need to add this to our FAQ or release note.

Thanks,
Raymond

I've just run through what you have described and it works ok for me.
Could
it be a java level thing, which JDK are you using? I have:
java -version
java version "1.5.0_10"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_10-b03)
Java HotSpot(TM) Client VM (build 1.5.0_10-b03, mixed mode)

  ...ant


I just ran it too and it works for me...

WinXp SP2
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build pwi32dev-20070201
(SR4))

IBM J9 VM (build 2.3, J2RE 1.5.0 IBM J9 2.3 Windows XP x86-32
j9vmwi3223-2007020
1 (JIT enabled)
J9VM - 20070131_11312_lHdSMR
JIT  - 20070109_1805ifx1_r8
GC   - 200701_09)
JCL  - 20070131
