Check List

1. Create package:  Workbench:Projects:Add
2. Create BeanGroup, if haven't already done so for Session Beans:  Workbench:EJB:EB panel:Add.
3. Create Entity Bean:  EJB tab: Enterprise Beans panel:Add >ejb.  Note add fields and methods through wizard.
4. Add members to Remote Interface (automatic option through wizard; manually add any additional methods).
5. Add Schema and Map from Beans Panel: Add
6. Check Schemas:  Beans Panel: Open To > Schema Maps
7. Export Schema to Database: EJPTab:Beans panel:Open To >Database Schemas :Schema Browser:Schemas panel:Import/Export>Entire
8. Generate Deployed Code: Bean Panel.
9. Open To > Server Configuration
10. Check properties on Server Configuration to be sure DBMS parameters are correct.
11. Start Naming Service: WTE
12. Start EJB Server
13. Run Test Client: EJB Panel
