Hi sohil, Thanks, i grab the code. I did build. Now i have all .sar, .war and .ear files in my local system(Ex C:\JBossPortalSrc-2.4.2-Final\JBoss_Portal_Branch_2_4\core\output\resources...). Can you please tell me exactly what i have to replace with my existing production Jboss portal to solve the unique constraint problem, Because i did lots of customization in my current production portal. I don't want to loss my previous work. Your advance reply will be appreciated.
