Just saying your application is "showing errors" doesn't tell us anything that would be useful in helping you solve the problem. This link may help you determining what we need to know.

Using code tags and other UBB tags makes the post much more readable. Please have a look at this link.

My first recommendation would be to change login.html to login.jsp and change all input tags to struts tags. The way it is currently, if there's an error on the page, the values entered by the user will disappear when the page is returned. You will also need to add an <html:errors /> tag to the page so that any error messages generated will be displayed.

Please post your login.jsp page. I'm particularly interested in seeing your html:form tag.

The problem is with the following line:

The property is misspelled. It should be userName instead of username.
