[Bikash Paul]

Hi all friends,
I am new to EJB-J2EE and I am trying to deploy 'Bean-Managed Persistence' example of Entity Bean(which is Account transaction) on J2EE Server which is come with J2sdkee1.2.1 Documentation.When Iam trying to deploy this example on J2ee server it is giving me Error "javax.naming.InvalidNameException: JNDI name enter 'jdbc/Cloudscape' for resource reference 'jdbc/AccountDB' is not valid". But I set this JNDI name as per given Guideline on Documentation for this example.Another Problem Iam facing is When I tried to create table "account" in AccountDB Database by using given 'CreateTable.bat' file which is located in c:\j2sdkee1.2.1\doc\guides\ejb\examples\util\ then it is giving me "ERROR:File not found CreateTable.sql".I first created 'AccountDB' Database by executing 'CloudJ.bat' and then I tried to create 'account' table in 'AccountDB'then it is giving me above metioned error.Cloudscape database is running perfectly and database 'AccountDB'also created successfully.But I couldn't understand why it is giving me this error.Can any one plz guide me how I can slove this problem.
