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. ---- 2010-11-07 00:39:58,878 INFO [STDOUT] INFO 07-11 00:39:58,877 (SecurityServiceImpl.java:login:75) Logging in user [admin] 2010-11-07 00:39:58,886 INFO [STDOUT] INFO 07-11
