Question

please bear with me. I have lost afew too many hairs over this code. Here is the sqlj file I am using in the jdeveloper 3.2.

I keep getting the following error from sqlj file. : SQL Error:ORA-00904: invalid column name . Actually all the tables and columns exist. I use sql plus, same connection, and everything is fine. As you can see in the sqlj file, I have tried everything including JDBC. It simply wont work. I use the same connection for BC4J, it works. The connection works in SQLJ too, but My co-workers and I can't figure why it doesn't work. We have looked at the Oracle samples without luck. Can someone tell us what to do with this? It would be greatly appretiated.

Hi Guys, isn't this frustrating? Anyway, I gave up on that issue and decided to create a bean to replace that SQLJ code. Strange as it may sound, the bean didn't work either. Another developer suggested rebooting the machine, and voila; The bean works without a hitch. I still have no clue why SQLJ didn't work. Here is the bean implimentation.

Here is the same connection but done the way the documentation shows. IT DOESN'T WORK. Compare that to the one above.
String myhost = "146.76.1.19";
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@(description=(address=(host=myhost)(protocol=tcp)(port=1521))(connect_data=(sid=devl)))", "pgat490", "pgat490");
If you ask me, I suspect that the second syntax won't register the driver. Anyone know why it doesn't work? I still have a lot of unanswered questions eg the SQLJ ones. So simple yet a bear to get working. I am worn out from having to discover everything by trial and error. I know Java but this tool is something else.
