Pl check the CLASSPATH, make sure that, the action form "RegForm" must resides in WEB-INF\classes\net\com\struts\form\RegForm directory (If you are using Tomcat).

Why do "properties" attribute of html:form tag like this,



PL specify the properties name SAME as that defined in ActionForm,

Correct :

The difference lies in the way you defined "property" attribute in html:text tag. You are supposed to take text field value in underlying bean (RegForm) variable, like in firstName, lastName, etc

Here is Form properties/varaible,


I just want you to replace your existing JSP(reg.jsp) code with the modified JSP which I posted earlier.

Let me know whether this works or not .

I don't know whether this works , but this is the issue related to Struts 1.1, but I'm not sure .

Just give it a try ,

Just comment the validate method,



comment the whole method body and re run.

Lastly, Which version of Struts you are using ?
May be we are missing any Struts libraries , make sure you get all the basic Struts libraries of version you are using !!

Actually i got the same problem when i am doing it manually (without any IDE) and for not putting the .class file in classes folder..
so check out whether you put .classes files in classes folder after compiling it..
