Newbie: Forms Installation/Configuration problem

Hi,

I can successfully build a test form - it links to the database fine, so I can create a single base table default form under scott/tiger. It compiles succesfully. However, when I try to run I get:

TNS-12560: TNS:protocol adapter error

I have seen references to this error but with many causes, so I'm not sure which configuration step I'm missing.

Perhaps if I describe what I did, the ommision may be obvious. I'm working on a single stand-alone Windows XP pro machine running the latest versions 10g of the database and developer.

I installed the enterprise database successfully to c:\oracle with orahome = c:\oracle\product\10.1.0\Db_1, orahnam = OraDb10g_home1. Sqlplus etc work fine.

I install developer to another directory c:\oracle\OraDS10g_home1 and orahome equals this with orahnam = OraDS10g_home1.

I installed jinit.exe.

I then start OC4J instance from the windows start menu under <Forms Developer> It states it is initialized.

I have done no other configuration at all.

I can build and compile the form as I described above using <Forms Builder> but when I try and run it I get the 12560 error.

When I start Oracle Net Manager and look at: <Listener><Other Services> I see Program name = extprog,SID=PLSExtProc, Oracle Home Directory = c:\oracle\OraDS10g_home1 <Listener><Listening Locations> Host = localhost, Port=1521.

Scouring the web I have seen mention of tnsnames.ora so I include both the database and developer directory versions below.

If any other info is required just let me know.

TIA for any help.
