I know, I know ;-)

Sure, the directory is correctly copied.

But with your hint, I realized that in fact the processes are not deployed.

I redeployed the processes and got this:

ERROR - GeronimoLog.error(108) | Deploy failed; BPEL compilation errors.
org.apache.ode.bpel.compiler.api.CompilationException:

(I lost this information on the previous deploy because of a restart of
Tomcat before the tests)

Seems to be complaining about the lack of a method in
org.w3c.dom.Attr.getTextContent() wich is implemented in all DOM 3
implementations...


I'm running Apache ODE in Mac OS X and using Java 1.5.0_07

Does this means the problem probably is in Xerces, the one included in my
Tomcat or the embedded version in the jdk? Maybe Mac OS has one hidden
somewhere?
