Hi folks....  I sent this message to the Enhydra list and haven't received
any responses.  Maybe I'm being too impatient, but maybe this is an
instantDB problem anyway, so I thought I'd send it to this list.

Any help would be greatly appreciated.  Note that I'm running Linux 6.1 with
Enhydra 3.0.1.

Thanks,
-Randy

Subject: instantDB connection problem


Hi all,

First off, I'll warn you that I am still somewhat an Enhydra newbie, but am
enjoying the learning process.  I am grateful for Enhydra itself and all the
work of the Enhydra community.

I am working on a database-driven ASP-based site to deliver to a client, and
thought it would be a good learning experience to develop an Enhydra
version.  I have installed instantDB (v3.13 and v3.14b5), and set up the db
schema with DODS successfully.  However, when I "./start" the application, I
get a NullPointerException.  Below are excerpts from my .conf and the
Enhydra log.  Nothing at all is logged or changed within the database
folder/files.  The database name is "ranches".

My questions:
-------------
- Obviously, what am I doing wrong to get the NullPointerException?
  (Does it have to do with the username/password?  I don't know how to set
this up in instantDB.  Accessing the db with "java JDBCmain" seems to work
fine though.)

- Are all the ".Connection." entries necessary in the .conf? (Besides the
URL, of course.)

Thanks for the help!
-Randy
