DB problems in JBoss-2.4.10_Tomcat-4.0.6

[Hiram Walker]

Hi, I'm having some problems with jboss and the conection to an oracle 7.3 database. I have a simple helloworld application with a jsp, a servlet and a ejb, which connect to the database. When I start jboss with the run_with_catalina option, I get the following exception in the log:

[15:35:15,010,XAConnectionFactory] Starting

I'm using the embebed tomcat JBoss-2.4.10_Tomcat-4.0.6, and win 98.

Here are some settings:
---------------------jboss.conf-----------------------
<MLET CODE="org.jboss.jdbc.XADataSourceLoader" ARCHIVE="jboss.jar" CODEBASE="../lib/ext/">
<ARG TYPE="java.lang.String" VALUE="StaffingDB">
<ARG TYPE="java.lang.String" VALUE="oracle.jdbc.xa.client.OracleXADataSource">
</MLET>

--------------------jboss.jcml--------------------------
<mbean code="org.jboss.jdbc.JdbcProvider" name="DefaultDomain:service=JdbcProvider">
<attribute name="Drivers">oracle.jdbc.driver.OracleDriver</attribute>
</mbean>

<mbean code="org.jboss.jdbc.XADataSourceLoader" name="DefaultDomain:service=XADataSource,name=OracleDB">

<attribute name="DataSourceClass"> org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl </attribute>
<attribute name="URL"> jdbcracle:thin:@172.16.254.5:1521:msal:ORCL </attribute>
<attribute name="JDBCUser">default</attribute>
<attribute name="Password">default</attribute>
<attribute name="MinSize">2</attribute>
<attribute name="TransactionIsolation"> TRANSACTION_SERIALIZABLE </attribute>
</mbean>

-------------------jndi.properties-------------------------
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.namingrg.jnp.interfaces


All this files in the catalina/conf directory.
And I put classes111.zip in lib/ext directory.

I've set all enviroment variables, and if i run the example without connecting to the database I had no problem, but when I try to connect, I got the following error:
[15:35:39,950,STDERR] java.lang.NullPointerException
[15:35:39,950,STDERR] at org.jboss.pool.jdbc.xa.XAPoolDataSource.getConnection(XAPoolDataSource.java:249)

Well, thanks to all in advance, Hiram.
