WSDL2Java from java question

Hello
I use CXF 2.6.7 with SOAP Web services. CXF is really fun.
But I have a problem with WSDL2Java.
I have written an Eclipse plugin and I run in it WSDLToJava. When it runs, i
have in the Eclipse console the command 'wsdl2java…' with all my arguments.
If I copy this line and submit it from a shell or bat (use bin/wsdl2java) it
runs runs fine and the classes are generated.
When I run the run method and the wsdl2java class instance : run(new
ToolContext()) (after setting of arguments) I have the following message

The generated command is

wsdl2java -d

-wsdlLocation /ws/wsdl/TESTSRV1.wsdl
-wv 1.1
file:/Users/michel/Developpement/Workspaces/TESTSRV1_Project/Properties/ws/wsdl/TESTSRV1.wsdl

As I said below, this command runs fine in batch mode.

I have run the eclipse plugin is debug mode I think that the problem is in
WSDL11Validator in method getDefaultSchemas. When it runs fine, then all
schemas included in cfx-2.6.7.jar (schemas.wsdl), via the classpath, are
set in the list. With the plugin, these schemas are not found…

I don't understand why because the plugin has a good manifest declaring the
following classpath:
Bundle-ClassPath (lib/* are valid) : .,
lib/wsdl4j-1.6.2.jar,
lib/commons-collections-3.2.1.jar,
lib/commons-lang-2.6.jar,
lib/commons-logging-1.1.1.jar,

An idea ?
Thanks.
