> -----------------------------------------------------------------------------------------------------
>
> Key: DBCP-128
> URL: https://issues.apache.org/jira/browse/DBCP-128
> Project: Commons Dbcp
> Issue Type: Bug
> Affects Versions: 1.2.1
> Environment: Operating System: Linux
> Platform: PC
> Reporter: vegandy
> Fix For: 1.2.2
>
> Attachments: BasicDataSourceExample.java.patch
>

> Code I'm working with uses a Connection as a key in a Hashtable, and while I was
> trying to move from DbConnectionBroker to DBCP, I ran into some problems.
> When retrieving the value from the Hashtable using the Connection originally
> returned by BasicDataSource.getConnection(), I don't get the value back that was
> inserted into the Hashtable. I get null instead.
> I've provided a patch to BasicDataSourceExample.java that can be used as a very
> basic test case. For the purposes of the test, I set up HSQLDB (originally this
> was discovered using JSQLConnect to connect to a MS SQL Server DB), and, using
> the HSQLDB's DatabaseManager, populated a database with the test data (Options
> -> Insert test data).
> The patch to BasicDataSourceExample.java the will get a connection, use it to
> insert a string into a Hashtable, then do some tests that show the problem,
> while still succssfully retrieving data from the database.
> Also in the patch are changes so you can provide all the arguments at the
> command line.
> I tested this with DBCP 1.2.1 with it's dependencies and with the nightly dump
> http://cvs.apache.org/builds/jakarta-commons/nightly/commons-dbcp/commons-dbcp-20060509.tar.gz,
> with the latest releases of commons-collections and commons-pool. For both tests
> the j2ee.jar was version 1.4 and hsqldb.jar was version 1.8.0.2.
> Here's the output from the session with the latest nightly build:
