hai dan,
If I am not wrong, try to close all the connection string and make the user defined variables as null. (Eg) 1) (Statement object)--à st.close(); 2) (String)às=null; Hope it will solve your problem to some extend, even then if your problem is not solved. Then you have to change the heap size in the tomcat server (that may be relative to RAM size of the machine where the tomcat is running). -- with Regards S.Prakash
