Application Development Software

We have installed Webcenter sites Content server 7.6 patch2 on Apache Tomcat 6. Now we have deployed the gadget server and community server 1.1.1 on top of content server 7.6 patch2 using the Installation guide for gadget server and community server. Now while we are starting the tomcat server it throws the following exception:
