Class 'com.uc4.ecc.ae.commons.content.uc4objectview.ToBeRemovedCompatibilityEvents' was not found because bundle com.uc4.ecc-plugins-usermanagement  does not import 'com.uc4.ecc.ae.commons.content.uc4objectview' even though buncle com.uc4.ecc-ae-commons  does export it. To resolve this issue, add an import for 'com.uc4.ecc.ae.commons.content.uc4objectview' to bundle com.uc4.ecc-plugins-usermanagement 
Package 'com-uc4.ecc.ae.commons.content.uc4objectview' is imported by bundle com.uc4.ecc-ae-commons  from bundle com.uc4.ecc-ae-commons , but the exported package from bundle com.uc4.ecc-ae-commons  does not contain the requested class 'com.uc4.ecc.ae.commons.content.uc4objectview.ToBeRemovedCompatibilityEvents'. Please verify that the class name is correct in the importing bundle com.uc4.ecc-ae-commons  and.or that the exported package is correctly bundled in com.uc4.ecc-ae-commons .
3) Replace the .war file in use with one from the Automation Engine image and re-start Tomcat. 4) Obtain the .jar file directly from the download center and replace.
5) Check the setenv.sh file for Tomcat - there may not be enough memory allocated. Example:
The first line sets Tomcat memory, but the third replaces it. This means Tomcat will start with 256M memory. This was causing Tomcat to error, and it didn't have enough memory to display even the basic views.
