Tried to install everything from scratch on another environment (java is 1.6
specifically this one is 1.6.0_11, the other I think was 1.6.0_21, both
windows unfortunately), again this time following carefully the installation
procedure based on the Drools Installer. Everything went smoothly and this
time the application server used was jboss-4.2.3.GA as specified in the
build.xml . I did install latest drools eclipse plugin and created the
sample process/flow files in drools project. But after adding to guvnor at
the defaultPackage, i got the same annoying error when trying to compile the
package,
unable to parse xml : Exception class java.lang.NullPointerException : null
as a result nothing appears in gwt-console etc
Can someone please help me out?? I also provide, at the end of this post,
the log from server.log after logging in and compiling the package in
guvnor. Tomorrow, i'll try to debug the source to find out why i get this
NullPointerException. I'll post as soon as i find out something. Thank you
for your time.
