Hi I am able to deploy the ejb on ubs 7.2 and i am able to run it successfully. The findByPrimaryKey and the remaining methods are working fine. But when i tried to insert data using create method the ejb server is getting strucked and its not responding for a long time. I am using MS SQL Server 2000 as my RDBMS, i have a doubt that there is some dead locking happening. If any one faced this problem and had a solution please let me know. Thanx. Lokesh.
