[njust_wmh]

when i run a client (standalone application ) of a ejb,i get information like this::
javax.transaction.TransactionRolledbackException: ejbCreate: Table not found: SAVINGSACCOUNT in statement [insert into savingsaccount values ( '123' , 'Duke' ,'Earl' , 0.00 )];

but i'm sure the table savingsaccount has been created.

can you tell me what's wrong ????

i have find the reason.

i use the code like this to get dbconnetion
private String dbName = "java:comp/env/jdbc/SavingsAccountDB";

InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(dbName);

but the dbName is not right. It should be "java:/InformixDB".
