Hi All, I wrote my web application to generate a report , I was using
BIRT Engenie, but when I run the program into WebSphere for create a
pdf file the application show me this:

Error 500: #{VendorsList.printList}: javax.faces.el.EvaluationException:
java.lang.LinkageError: LinkageError while defining class:
org.eclipse.birt.report.model.api.activity.SemanticException Could not be
defined due to: org/eclipse/birt/report/model/api/activity/SemanticException
(Unsupported major.minor version 49.0) This is often caused by having a class
defined at multiple locations within the classloader hierarchy. Other potential
causes include compiling against an older or newer version of the class that has
an incompatible method signature. Dumping the current context classloader
hierarchy: ==> indicates defining classloader ==>[0]
