How to really relate entity beans to database table?

[constant]

Hi, everyone!

I have some problems with entity beans. The envirenment is as follows:

Windows 2000 Server
JBuilder7 integrated with JBoss 3.0.2
MicroSoft SQLServer2000
MS SQLServer2000JDBC driver installed

I created an CMP entity bean which was configured to relate to a table called TaxEJBTable. It seemed to work, since the EJB replied correctly to my test client, however, when I checked the database, no data had been written to the table. I clicked the Test Connection button to test the connection, it succeeded. What's the problem? How to get rid of it?

I'd like to clarify the problem--it was an EJB 1.1 CMP entity bean.
