When I connect to my database, I can't see my tables, but if I use another tool, I can see them fine. Where are they?
NetBeans shows the tables only under a single schema. You may be connecting to the wrong schema. To change this, disconnect your connection, right-click on it and choose Properties, and then set the schema property appropriately. The other reason you may not be able to see any tables is if your driver doesn't correctly support database metadata. Try upgrading your driver. If you're using Microsoft SQL Server, try JTDS at http://jtds.sourceforge.net.
