Connecting to PostgreSQL via web

Thanks much Jason.

I am trying to connect to the pgsql database from a jsp application. The
database, webserver and the application are all running locally.

The problem is that I am able to read data from the database successfully
but am not able to write to it. I also don't get any SQLException message. I
simply get a blank page. The connection is opened using:

Connection con = DriverManager.getConnection("jdbc:odbc:PostgreSQL_test",
"Administrator", "<pwd>"); // PostgreSQL_test is the user DSN

The statement creating the problem is:
rs.updateString("middle_name", "Joe");

I am able to successfully edit fields using pgAdmin though. Also, String
strTemp = rs.getString("first_name"); works fine.

Would appreciate help. My system information is:
Windows 2000
Sun ONE Community edition IDE
Netscape 7.0 eternal browser
Field middle_name is VARCHAR 255

Thanks
Manish

I thought of suggesting removing the .pid file, but I thought the error
message for that case was different than what you reported. In
hindsight, I don't know how I missed the following:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I apologize for not suggesting the above earlier.

I'm glad that you are up and running.
