Thanks for the prompt reply. Its a late 90's huge application in which now i cannot start using Strus 2 as iam the only developer working on this. We are using html in java code because the JSP changes at run time according to the user inputs . Yeah , i agree that coz of diff environment we face lot of problems but i cannot do anything as its not my decision. We run Apache as a front end for Tomcat. Apache serves up the html pages and uses mod_jk mounts to forward the java application requests to Tomcat. I'll try to find out what else i can do as i am unable to see anything in apache logs as well.
