Running JIRA on Websphere fails with error:
java.lang.ClassNotFoundException: class com.atlassian.jira.security.auth.trustedapps.TrustedApplicationFilter :java.lang.NullPointerException
The WEB-INF/classes/entityengine.xml is not compliant (well-formed) XML. WebSphere does not display error messages about the XML not being well-formed. Instead it displays the spurious error message above.
Ensure that The WEB-INF/classes/entityengine.xml is well-formed and valid. Test entityengine.xml by opening it in Internet Explorer or Firefox.
Use Tomcat Application Server which is part of JIRA's Supported Platforms
