Title: [JBoss-user] Minerva with Oracle
|
A null pointer exception connecting to Oracle is
usually due to the inability to establish a connection, which the connection
pool attempts to do at startup. Make sure you supply a valid userid and
password in jboss.jcml, and that your URL is correct.

Subject: [JBoss-user] Minerva with
Oracle
Hello jboss-user,
What should I check I'm not getting the minerva connection pools to work with
Oracle.
We have Oracle8.1.5 personal
edition installed.
Have tried with both
the
JDBC Drivers for JDK 1.2.x.
I have setup the 2
configuration files correctly I believe according to the documentation.
(Although I have included them for reference purposes).
<<jboss.jcml>> <<jboss.properties>>
It seems to start the driver OK. But
when I attempt to start a connection pool. I get an exception.
The output when starting up
the server is the following:
C:\JBoss-2.2.1\bin>run.bat
JBOSS_CLASSPATH=;run.jar;../lib/crimson.jar
jboss.home =
C:\J2eeAppServers\JBoss-2.2.1
Using configuration "default"
