I had similiar problems yesterday i.e. get the same error message with the
create usecase and had a rather long debugging session in order found the
problem (note that i use cocoon-2.1.8-dev and tomcat).
The problem starts here:
StreamResult result = new StreamResult(file);
in the DocumentHelper class i.e. i got a systemid = "file:/....." instead
of "file:/// ........" which can be traced back to
javax/xml/transform/stream/StreamResult.java. The funny thing was that the
problem did not occur if i used jetty (on a SuSE linux system).
So what was the actual reason for this:
- I use cocoon-2.1.8-dev and its xml-apis.jar is different to the one in
cocoon-2.1.7 and also differen to $LENYA_HOME/lib/xml-apis.jar (the
build process did copy the one from cocoon to
build/lenya/webapps/WEB-INF/lib).
Comparing the StreamResult.class of both jar's show that they really
differ. I could not have lookd into the code because i did not have the
source of the xml-apis.jar used by cocoon-2.1.8-dev.
If I did use the $LENYA_HOME/lib/xml-apis.jar then i did not get
this message and all works fine.
- BTW jetty is only working because it uses the native api from the jvm at
least on my linux box.
I will start a new thread concering the libraries in order to discuss my
findings.
