Title: RE: [jBoss-User] Bean Managed Persistance Using Oracle

Robert,

The sample you have used oracle.jdbc.xa.client.OracleXADataStore, is this the case, or is the example wrong ?

I don't know the solution, just providing another set of eyes, did you mean
<ARG TYPE="java.lang.String" VALUE="org.jboss.minerva.xa.XADataSourceImpl">

Hope this helps

Regards

Subject: [jBoss-User] Bean Managed Persistance Using Oracle

I am new to EJB and JBoss and am having trouble getting a sample from
"Enterprise JavaBeans" by Richard Monson-Haefel, Chapter 6, page 179 using
bean-managed persistance. I am trying to use an existing database that I am not
having any problem accessing using servlets. I have been trying to just start
the JBoss server with the suggested parameters and am having problems. I saw in
the mailing list archive that there was a problem of this sort sent in last
October and was wondering if any progress was made on it.

From the instructions that I found in the JBoss documentation, I have done the
following:

I retrieved the Oracle drivers ( Oracle8i 8.1.7 JDBC Drivers for use with JDK
1.2.x for NT, classes12.zip ).
I then put the classes12.zip into C:\JBoss20\lib\ext\.

I modified C:\JBoss20\conf\default\jboss.conf to include the following ( If I
use oracle.jdbc.xa.client.OracleXADataStore, I get a NullPointerException ):

I modified C:\JBoss20\conf\default\jboss.jcml to include the following:

   <mbean name="DefaultDomain:service=XADataSource,name=titanDB">
      <attribute name="URL">jdbc:oracle:thin:@myhost:myport:mysid</attribute>
      <attribute name="JDBCUser">myuser</attribute>
      <attribute name="Password">mypass</attribute>
   </mbean>

When I started the JBoss server with the following command file:

cd %JBOSS_HOME%\bin
java -jar run.jar

I got the following error:

   java.lang.NullPointerException
           at org.jboss.logging.Log.log(Log.java:95)

Any help would be appreciated.

Bob
