Migrating JSF-Application to Weblogic 12
问题 We developed a Seam 2 based Java EE 5 application and it runs on Weblogic 11g. Now I tried to deploy the same WAR file to the new Weblogic 12c (12.1.1.0 on my local Windows 7 machine) by following the same steps as on the previous WLS, including the deployment of the required JSF 1.2 library. The deployment and start of the application works fine, but when I open the URL in the browser, I get an 500 error and the logfile shows the following exception: java.lang.UnsupportedOperationException
