Exception starting filter struts2

[sitaramaraju psn]

Iam struggling to crack the issue since last two days and not able to find the root cause.I'm new to web development and asked to learn and work on Struts2.

The example contains both struts1 and struts2 functionality as it is a migration example.

Step1 : I downloaded sourcecode from following URL:http://www.infoq.com/articles/migrating-struts-2-part3
Step2: Downloaded content is a maven style project structure and downloaded all jars that are needed by following pom.xml .
Step3: Created a Empty Web project(Example) and Copied the extracted srcfolder to eclipse src and added resouces folder containg strutsproperties,struts.xml to it
Step4: Deleted the Web content folder of eclipse and added webapps folder in my project example.
Step5:Created a lib folder and add jars that i downloaded with reference from pom.xml and added jars in the build path and deleted pom.xml from project.
Step6:The changes I made in the to the downloaded content are as follows in my first attempt are just changed webwork to struts2 in web.xml
Step7: On running I got some as mention below in my eclipse.(Console and 404 fromapache )

Note: Not included entire source code as it is already available in Net at http://www.infoq.com/articles/migrating-struts-2-part3.

Expecting Help from experts and Thanks a lot for reading my post i.e for your valuable time.

I check for existing posts but none served my purpose so, posted finally after 2 day long struggle to crack the mystery.

It's clearly saying there is problem in the configuration file. (web.xml) or (struts.xml)

[sitaramaraju psn]

Your right . but that was resolved when i performed Step 7 that you are mentioning in your post but still the console shows the error that is posted under step7.



i knew where the issue probably lies thats why I tried by all possible url patterns in web.xml but still not able to understand how to resolve the issue.As this example contains both Struts,Struts2 implementation in same project it had Struts.xml for Struts2 and also struts-config.xml for struts so I had not changed anything after importing into Eclipse and I clearly mentioned the changes I made in web.xml to the downloaded content.

I'm Dam new to Web development and novice to Struts2 Framework but curious to learn please help and would be indebted for your help.

I urge any one to deploy the zip available @http://www.infoq.com/articles/migrating-struts-2-part3 into an eclipse to resolve the Issue.

I knew what i am begging you is Your valuable time .I choose this example as it is simple and gives clear picture of Struts building blocks in details and this zip contains code of same example in both Struts and Struts2


try,try,try till you succeed................................

[Mohana Rao Sv]

specify, what are the files you are included in the project. Expecting struts2-core-2.x.xxx.jar file is missing.
