Hi sohil, Thanks for your mail, But i downloaded (JBoss Portal + JBoss AS 2.4.2 CR1) on 2007-03-07. I hope this version is a final version of Jboss portal 2.4.2 Final. I worked with this version last 40 days, At that time, I can able to uploaded huge files and small files and(All kind of files). But now i am not able to upload any files, Facing Unique constraint problem(above problem). Accoarding to my understanding it's not a huge file problem. I am waiting for your suggestion, How to solve this problem, Your advance reply will be appreciated.
