We are currently attempting to migrate our application from Struts 2.2.3 to 2.3.34. However, we are currently facing issues with the migration. Here are the steps that we have already performed.
1. Replaced necessary JAR files & required dependencies. 2. Changed DTD in struts.xml 3. Changed DTD in tiles.xml 4. Modified web.xml file and changed org.apache.struts2.dispatcher.FilterDispatcher to org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter 5. Modified web.xml file context-param to <param-name>org.apache.tiles.impl. BasicTilesContainer.DEFINITIONS_CONFIG</param-name> 6. Added the ff in struts.xml: <constant name="struts.additional.excludedPatterns" value="^(action|method):.*"/> <constant name="struts.enable.DynamicMethodInvocation" value="true" /> We would just like to know if there are additional changes that we need to do in our java/jsp/xml files. This is because we are getting errors such as these when executing actions: No result defined for action com.MyRequestAction and result fileSizeError This error did not appear before our migration. Our results are correctly defined in our struts.xml. Hence, we are not certain why the error was returned to us. Thanks!
