Hello I am also trying to use Oracle with NetBeans 5.5. As you said I have copied the oracle-ds.xml file to the server\default\deploy directory. Created the Database Connection with the database and also Execute Command to see if i can get the data from any table. It is all working fine. Now I am trying to make a Entity Class from Database. But after I select the DataSource, there is a Table in the screen which should be populated with the database tables but it is not showing any tables from my database. What should I do to see the tables so that I can select the one for which I want to create an entity?
