This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I have a login form and a registration form on the same JSP page. I have server side validations attached to both. I'm using <html:errors> tag to print out the validation errors. I want the validation errors returned by the login form to appear in the area above it, and those returned by the registration form to appear above it. When I use <html:errors> at both places, the same errors are printed at both places when any one form fails validation. How can I write code to detect which form caused the error, so that the errors appear only at the right place ?
