Hi.

First i will paste all my code here.

DataPage.jsp


DataServlet.java


This two are dependent on each other, wright? I have other jsp page which is dependent on other servlet. Code is below


Insert.jsp


Insert.java



Now. The insert.jsp works fine, when I give data and click add button, the database is also updated. Till here its fine

THE PROBLEM:
In DataPage.jsp I am viewing the list sent by the servlet "DataServlet". So if i run the DataPage.jsp directly I get an error at the itterator. However, I accessed the DataServlet from the browser then i get this error "HTTP method GET is not supported by this URL" which i used to not get in the beginning. This started after I added the Insert.jsp and Insert.java files. I am unable to solve it. Someone please point out the problem.


Thanks and regards
Adeeb

Hey i missed this point. I tried to access DataServlet from different jsp file using a submit button and form with method as post and all.. Here the URL Shows up with /mypath/DataServlet. But the most annoying thing is its not behaving as it should i.e displaying database table by redirecting to DataPage.jsp, as the code is written, instead it shows the window of same Insert. NOTE:In URL name is DataServlet, but it shows Insert page. How come??? I restarted Apche many times, recompiled the code. Dont know the problem. Please help me out.


Thanks.

You are forwarding from the servlet to the JSP. So why is this a surprise? It's doing exactly what you told it to do.

The problem is I dint know about xml tags. I wrote like this
<servlet>
<servlet-name>DataServlet</servlet-name>
<servlet-class>DataServlet</servlet-class>

<servlet-name>Insert</servlet-name>
<servlet-class>Insert</servlet-class>
</servlet>

instead of writing individually.
I was surprised cauz, even the URL was wright, but page displayed was different..
Now its resolved. Thanks.
