What is the URL you are submitting when you get this request? Are you calling an action or going straight to a jsp?

I am calling jsp page.And My URL is

http://localhost:1982/StudentPotral/form/supdate.jsp

If you request a JSP directly you are bypassing the Struts framework. Struts will not create the form bean for you, thus the Struts form tags will fail.

Then how i can show this page.
Please help me.

Go through an action. If you're using Struts form tags, you have to have an action form. To get an action form you can't bypass Struts by going directly to a JSP (which is generally frowned-upon anyway).

Still i am getting the same error.Even i use action .

But at the console i am getting this error.

java.lang.ClassNotFoundException: com.yourcompany.struts.form.UpdateForm

at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1340)

Do you have an UpdateForm class? You also need to include the actual mapping for the action you're accessing; it wouldn't be trying to access an UpdateForm class if you didn't tell it to.

The errors you're getting provide all the information you need to solve your problem. When you provide source and configurations please use the UBB code tags so it's formatted in a readable fashion.

Thanks Sir i got and find the solutions.
