[rules-users] Unable to upload POJO model jar to Guvnor 5.3.1 on Glassfish 3.1.2

Hi All. I have deployed Guvnor 5.3.1.Final (the Tomcat 6 war modified to add a glassfish-web.xml to set class-loader delegate="false") to Glassfish 3.1.2. I am able to create a new package and a new POJO model in the package, but when I try to upload the model jar file, I get the error "Unable to to upload the file" message box displayed. I checked the log file (and even turned on debug log4j output in the guvnor war), but there are no errors in the log file from the upload attempt. I have attached the server.log file from glassfish. Has anyone had similar issues, or has suggestions on what else to try to debug the issue? Thanks. http://drools.46999.n3.nabble.com/file/n4017722/glassfishserver.log glassfishserver.log -- View this message in context: http://drools.46999.n3.nabble.com/Unable-to-upload-POJO-model-jar-to-Guvn...
