In my application I have a DocumentTemplate, which is used to generate a (pdf) document). During testing on localhost, it works fine. My pdf opens in the browser as expected. After deploying to the Acceptance Environment, it doesn't work anymore. In the log I get a message like 2013-09-19 14:10:25.356 CRITICAL - M2EE: An unhandled error occurred in the MxRuntime. 2013-09-19 14:10:25.356 CRITICAL - M2EE: java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(Unknown Source) at java.lang.ClassLoader.defineClass(Unknown Source) etc. etc. It doesn't help me a lot, actually. Has it anything to do with rights or do I forget something else?
There was an annoying classloading bug we thought we fixed in beta7, however apparently the conditions the cloud are slightly different, it looks somewhat like this error. Could you file a ticket for this and include a (test)project that gets you this error?
