NPE when using Struts 2 Jasper Reports plugin

When using mentioned plugin in Weblogic 11g you can get NullPointerException within Struts 2. To solve the problem you must enable the "Archived Real Path" global property in Weblogic admin console > configuration > Web Applications. It's because JasperReportsResult determines the report directory base on servletContext.getRealPath(finalLocation).

Convention based application doesn't work

When you deployed an application that base on the Convention Plugin and you get an error messages that says:

There is no Action mapped for namespace / and action name xxxxxx

create struts.properties file in WEB-INF/classes folder (in the expanded application's folder or in the source code) with below statements:

#struts convention property modifications for Weblogic
struts.convention.action.includeJars=.*?/yourwebapp.*?jar(!/)?
struts.convention.action.fileProtocols=jar,zip
