I have made a software/project as major project for college which involves 7 class files(.class) 122 Images and 1 Database(Microsoft Access 2007).It is a bulky project which do lot of things and continually access database.I have wrapped all .class files into a jar file to make it runnable by double click. Problem is when I run the project,javaw.exe consumes almost 90% CPU which makes the project slow responding.I am using JDK 1.5.0_22 installed on 2.80GHz. dual core processor 2GB RAM with OS Windows XP SP2. High CPU usage problem does not occur when I run other single java programs. I will appreciate your help,thanks in advance.
