I'm using tapestry5,maven,spring3.0.6.RELEASE and hibernate in my project and I'm stuck with this exception(the only possible solution I've found on Google was to replace openjdk implementation of java for the project with java-6-sun,but no luck,I still get the same error).
Here's the stack trace: 14-12-2011 12:57:42:333 11518 ERROR org.apache.tapestry5.ioc.Registry - Exception assembling embedded component 'exceptiondisplay' (of type
