I'm not seeing your struts.xml file.
Say suppose your action file name is validateLogin and action structure like this com.test.actions.validateLogin;
Then you have to map struts.xml file like this

The action name in the struts.xml must be same as the action name in the jsp.
Then only it will look on the particular action file.

Please show your struts.xml file and action file to us.Your problem will get resolved soon.
