Struts and jasper configuration issue

Question

I have got empty action name in error message when I was run my URL (http://localhost:8080/Jasper/myJasperTest.action). Even I could not find the issue by referring other stackoverflow Q's. I really appreciate if one of you can help me to sort out this issue. My project source code is mentioned below with my console error message. Thanks.

Error Message 
HTTP Status 404 - There is no Action mapped for namespace [/] and action name [] associated with context path [/Jasper].
