Best Way to Validate the JSP form by using Java

[YuenLian Wu]

Dear geeks,

I have some design questions regarding to the web form. My form has a lot of fields like Customer Name 1, Customer Password 1, Confirm Customer Password 1. I call those as a group. I have around 20 groups of that on my web form because of the user requirement. I feel so annoying that if I have to use the following validation code for each group,

    
if ( request.getParameter("cust_name1") != null && request.getParameter("cust_pwd1") != null || request.getParameter("ver_cust_pwd1") != null ) {
 
   // prompt error message
}

The above code is good for few groups, however, I have a lot of such groups and I need to validate one by one. I feel so boring if I just copy paste one set of code and pase it to the jsp and rename the variable names.

ANy better way to implement that ? Myriad thanks

Have you heard of the Struts framework ? Your values will automatically be mapped to variable names in classes. Do look into some example applications that use this.

Jakarta Commons Validators is your best bet.
