Oh yeah, and this is the source code for creating a connection:
protected Connection getConnection() throws NamingException,
SQLException, Exception {
this.CONTEXT = new InitialContext();
Connection conn = null;
if(this.CONTEXT == null ) throw new Exception("Context needed to
establish conection");
DataSource ds = (DataSource)CONTEXT.lookup("java:comp/env/jdbc/" +
this.DATABASE);
if (ds != null) {
conn = ds.getConnection();
}else{
return null;
}
return conn;
}
So it would appear it is blowing up on the line where its attempting to
create datasource. I read another Deja post not too long ago where someone
was saying that this error is often caused by not having the right context
path reference in the code for creating a Datasource. Someone else said
that you must define your datasource via the web.xml and then its avail for
reference. BUT, why was it working before (and why is it still working on
my laptop) with out the web.xml reference, and with these exact context
paths?
So confusing. :(

Subject: RE: DBCP Woes!
My setup? I'm using MySQL 3.23 and the latest version of (don't recall the
number) Connector/J for my driver. This is of course all sitting inside
tomcat 4.0.4. I have manually installed the DBCP, collections and whatever
other support classes I needed for DBCP.
I have configured DBCP via my server.xml file as such (below). When I was
recieving the error from (org.hsql) that was because I was also attempting
to creating a reference to the resource within my web.xml file. I have
since removed it and that error has ceased. The error I am currently
experiencing (javax.naming.NameNotFoundException: Name jdbc is not bound in
this Context) was happening last night. *Seemed* to spontaneously got away,
then this morning I loaded a few classes and rebooted and it started again.
I have since removed those classes but the error is persisting.
Its worth noting that I can still obtain connections directly through JDBC,
without the use of DBCP, no problem.
Please let me know if you can think of anything!!!!
Thanks!
Neal

I don't know your setup at all, neal, but this is a hypersonic database
reference. What is your setup?

I considered poolman but it doesn't look like its supported or even
available from the website to download anymore. Is this the case? I have
heard good things about it.
Don't suppose you understand this JDBC conext binding error, do you?
Thanks.

Poolman works nicely, I have little to no problems with it. Then again
I haven't used DBCP. But you'd still have had the exhasted connections
problem with poolman.

Subject: RE: DBCP Woes!
Now I have some other strange error related to accessing my
database. Ever
since I started messing with thsi stuff my conneciton to my dB has been
flakey at best. Sometimes it works ... sometimes it doesn't.
javax.naming.NamingException: Exception creating DataSource:
org.hsql.jdbcDriver
I don't even know where this class is defined or called!!!
:(
Neal
Still having DBCP problems.
I ensured that all my connections, statements, and resulset objects
are being properly released when using DBCP for connection pooling. I've
enabled recoverAbandoned. It seems that yes I did have some
connection pool
leaking,
but that has since been resolved. But I still get this message
(along with
a
failure) from time to time. Does anyone know why?
javax.naming.NameNotFoundException: Name jdbc is not bound in this
Context
This is a different message than I was getting when I was having
problems
with the DBCP pool being exhausted.
Thanks!
Neal
