Birtviewer with maven on weblogic Error with opening reports

I am using birt 4.3.1 with maven and deploying on weblogic.I deployed birtviewer in weblogic as "WebViewerExample-0.0.1-SNAPSHOT.war" and can open birtviewer with url localhost:7001/WebViewerExample-0.0.1-SNAPSHOT/..But on trying to open view example link or trying to open url localhost:7001/WebViewerExample-0.0.1-SNAPSHOT/frameset?__report=test.rptdesign I got this very long error.

`
Any suggestion please.Thanks in Advance
Solution
The problem here, is this class "org.w3c.dom.TypeInfo" is distributed both in weblogic server and in a signed jar of BIRT.
The smartest solution would be to resolve all conflicts and keep only one version of each class, but this might be very challenging.
A quick workaround would be to unsign the jar:
stop WebLogic
in libraries of the webViewer, locate the largest JAR file which should be named like org.eclipse.birt.runtime_4.3.1<buil-version>.jar
rename this .jar to .zip
within the archive, open META-INF folder and remove files such *.RSA and *.SF
rename .zip to .jar
restart WebLogic
I hope it helps
