Unable to load Action error while deploying struts2 war file on weblogic 10.3.6

The above question is very similar to the issue I'm facing but there is no solution provided. I have an application in struts2.5 which I have exported to a *.war file and trying to deploy it to weblogic 10.3.6(running on java7). During deployment I get an error that the Action class is not found (when I can see it present in the war file's WEB-INF/classes).

As mentioned by user3898783 in above link- "What weblogic does during WAR deployment(obviously it internally explodes) it puts all the files reside in web-inf/classes folder into jar called _wl_cls_gen.jar file and copies into web-inf/lib directory under domain stage folder." - similar is my problem. I am currently using the wls:prefer-web-inf-classes"true" /wls:prefer-web-inf-classes configuration in my weblogic.xml file which hasn't really solved my problem.

Weblogic.xml

<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.4/weblogic-web-app.xsd">

I checked my struts.xml(struts.xml:16:97) - and it is pointing to the LoginAction action class mapping, which obviously its not able to find under the weblogic "../domains/../mymanagedserver/tmp/_WL_user/myapp/4bdx7o/war/WEB-INF/classes"

Thanking you in anticipation

Finally I was able to figure this out. The culprit has been the compiler compliance level in my eclipse project. Although I was using jdk1.7 in my project buildpath, I should have also checked for the projects compiler compliance version in Eclipse which was 1.8 (proj right click> JavaCompiler> I set it to 1.7). Also, I was using javax.servlet-api-3.0.1.jar - I switched to servlet2.5 as I read somewhere that weblogic10.3.x is only compliant upto servlet2.5.

I hope this helps someone looking for a solution to similar problem.
