Hi,

Your main problem is on
java.lang.NullPointerException in org.apache.struts.util.RequestUtils.computeURL (RequestUtils.java:521)

I have never used JAMM but you may try to find the documentation especially for the RequestUtils file

RequestUtils.computeURL method is deprecated. I guess replacing the struts jar
with the latest version might help.

Hi,

It seems from the error that it's happening in the index.jsp and you must be using the redirect tag in it. Is it?
Could you please check for the attributes used for the redirect tag? r they correct?

or post it here..

regards,
fargo

Hi guys
Thank you for your responds. As I pointed out i am using Debian sarge. And i used deb. package to setup tomcat and java. I reinstall Tomcat from jakarta.apache.org and JDK from sun. Everything is getting ok. Sorry for taking your valuable time to post. Shortly get rid of the deb. package and use the sources codes:) There is no problem about jamm. But i wish they had pointed out the problem about debian in their documentations. I really spent my time to understand the problem. Thanx
