Subject: JSP question
> Hello All,
>
> I am pulling my hair on this problem, and since there are many Java
experts
> on this mailing list, I hope someone can help me on this.
>
> I have a simple servlet that calls a JSP page where the user can enter a
> search value. When the user clicks on the submit button, the search value
> will be passed back to the servlet for processing and display. All these
> are running on Tomcat 4.1.24.
>
> Everything works fine until I added the form validation routine in the JSP
> page. Initially, my input button type was "submit". I changed it to
> "button" and leave the submission to the form validation routine which is
in
> JavaScript. Now, when I click on the button, I get the error message of:
> "Object doesn't support this property or method"
> at the line of code:
> document.form1.submit();

> Does anyone know why? The following is code of the JSP page:
