I have downloaded and installed SDE for NetBeans Community Edition. Now i’m trying to repeat all steps in this tutorial : http://www.visual-paradigm.com/product/sde/ec/tutorials/sdeecorm.jsp . I’m using HSQLDB, and have succesfully connected in section “Configure your database” . But when i’m trying to syncronize ERD to class diagramm in section “Design database” step 8, i don’t see “Synchronize to Class Diagram” in the popup menu. What am i doing wrong? Please, help!
