Subject Re: DBCP validation query: how to use?
Date Sun, 09 Jun 2002 13:44:37 GMT

Actually the problem is in my code, there should not be any nulls at all
in the String I'm trying to insert. It's supposed to be a normal
human-readable string.

But talking about DBCP again -- how do I enable "ping" in configuration
of DBCP?

I'm looking at the source code for DBCP, and the "validateObject" method
in PoolableConnectionFactory is where the test occurs (on your
validation query). But either the code doesn't work, or validateObject
is never called in the first place. 

Again, help would be appreciated!

    But you can solve this in postgres :
    1. use BYTEA type for bynary strings.
    2. check the last driver version, I am not sure it is fixed in the last
    versoin, but it
    is no problems to fix it, driver is open source. Current "STABLE" version
    has this bug.
    Escape table you can find in user's guide.
