Hi,
Please remove the <servlet-class> tag line.the class created by the jsp gets all the info passed in thie servlet element.

hi,
we are having jsp-file and servlet-name in the servlet element to configure the jsp...to pass init parameters...to say apply everything there is to the servlet that gets created by this jsp.

Hi Vineela,
I read your problem last week and did a quick test to see if I got the same results. I didn't so see if you can spot any difference to what I did.
I'm using Tomcat 5.0.28
Heres the JSP:
I put my code here:
copy web\result.jsp c:\jakarta-tomcat-5.0.28\webapps\steven-jsp-II-examples\result.jsp
Can you spot any differences?
Steven

Hi,
I know it'd been a while since you posted this query - hope it must be resolved by now.
Anyways, I have the solution, posting it for the records -
What you also need to do apart from adding the servlet tag with the init parameters is to add a servlet mapping for the jsp. The mapping could be the same as you are already using to access the url.
Add this to your DD / web.xml and it should work:
<servlet-mapping>
<servlet-name>ServletTest</servlet-name>
<url-pattern>/FirstJsp.jsp</url-pattern>
</servlet-mapping>
I couldn't quite figure out why this is necessary - if you do happen to know the answer, just let me know.
Thanks,
