I have seen a lot of listings on this topic but have not yet been able to solve my problem. I would like to connect to a Oracle8i on a linux box from my JBoss on a win2000. I am
running JBoss-2.4.4 width Tomcat 4.0.1.

The error message I get is:

[INFO,OracleDB] Starting
[INFO,OracleDB] XA Connection pool OracleDB bound to java:/OracleDB
[ERROR,OracleDB] Stopped
java.lang.NullPointerException
at org.jboss.pool.jdbc.xa.XAPoolDataSource.getConnection(Unknown Source)
at org.jboss.jdbc.XADataSourceLoader.startService(XADataSourceLoader.java:412)
...
at org.jboss.Main.main(Main.java:106)
[ERROR,ConfigurationService] Unexpected error
java.lang.NullPointerException

at org.jboss.jdbc.XADataSourceLoader.startService(XADataSourceLoader.java:412)
...
at org.jboss.Main.main(Main.java:106)

The configuration I use is this:

<!-- ========================== jboss.jcml ========================== -->
<!-- ======= Transactions ========= -->

300

<!-- Use this attribute if you need to use a specific Xid implementation
Like JBoss recommends I have uncommented here -->
oracle.jdbc.xa.OracleXid


<!-- ======= JDBC ========= -->

oracle.jdbc.driver.OracleDriver



OracleDB

org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl

jdbc:oracle:thin:@machine_name:1521:database_name
username
password


<!-- ========================== jboss.jcml ========================== -->

java:/OracleDB
<type-mapping>Oracle8</type-mapping>
false

Could anyone please help me with this problem? Thx, in advance!
