Error 500 in servlet

[John Lincoln]

Hi,

I have two jsp pages, question.jsp and answer.jsp. In the question you can select questions and answer.jsp, you can answer the question. Also answer has a back option from where you can go back and reselect your questions.

But when i click the back button, the question page appears but at the bottom, i get the error message Error 500. Can someone who has seen similar problem, please throw some light.

Thanks

<Form method="post" name="form0" action="ChallengeServelt">
 
<input type=submit name=Submit value="Next">
<input type=submit name=Back value="Back">
</Form>

Can you post the question JSP page code?
It seems there is some code at the end of that JSP raises the 500 Internal Server Error.

With all those <'s in your psot it's near impossible to read. I'd suggest editing the post to repair the faulty code post.
