I don't see anything wrong in your struts-config.xml but the error is
probably in the JSP, which you didn't post. What does that look like?

Hello,
I am building a new Web App with the Struts 1.2.8 Action Framework and have a strange problem. I have build a login page a dynaform and a Action class for my app and if I test it I get the error that the form is Null ! I have misspelled the form name delibaretly and it gave the error it could not find the form. It seems like Struts would parse it right but does not put the form in the servlet. I hope someone can give me a hint because I am running out of ideas. Here is the error message:
