RE: [JBoss-user] NPE: org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl - Oracle8i and JBoss2.4.0

Title:

Paul,

 

I've seen this error before, it usually indicates that the connection to the databasecannot be made for one

reason, so check your database setup and you password/username -> configuration looks

alright.

Thanks Dragos, I wish that were enough .

 

My setup is currently:

 

  <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=OracleDS">
    <attribute name="PoolName">OracleDS</attribute>
    <attribute name="DataSourceClass">org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl</attribute>
    <attribute name="URL">jdbc:oracle:thin:@localhost:1521:jbossb</attribute>
    <attribute name="JDBCUser">xxx</attribute>
    <attribute name="Password">yyy</attribute>
  </mbean>

I have the drivers in classes12.zip in lib/ext

 

I still get an NPE at

 

[XADataSourceLoader] Stopped
java.lang.NullPointerException
        at org.jboss.pool.jdbc.xa.XAPoolDataSource.getConnection(XAPoolDataSource.java:178)

 

I cannot afford to spend anymore time on this, I never thought at this stage of the project I would run into an issue like this. Unbelievable. Luckily I have convinced my boss that HypersonicDB will suffice for now until a future release.

 

Paul.

I am using JBoss2.4.0_Jetty-3.1RC8-1, but as DB i'm using Postgre, not Oracle8.

 

This is my jboss.jcml entry for my DB connection pool:

 

<!--PostgreSQL connection pool -->

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

<attribute name="PoolName">PostgreSQLDS</attribute>

<attribute name="DataSourceClass">org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl</attribute>

<attribute name="URL">jdbc:postgresql://localhost:5432/play_with_ejbs</attribute>

<attribute name="JDBCUser">tog</attribute>

<attribute name="Password">secret</attribute>

</mbean>

Yes, it is.

 

What version of JBoss are you using. I am using 2.4.0

Thanks Dragos, this answer looked promising but I get a NPE!

 

[XADataSourceLoader] Stopped
java.lang.NullPointerException
        at org.jboss.pool.jdbc.xa.XAPoolDataSource.getConnection(XAPoolDataSource.java:178)

 

Surely someone out there must know how to use JBoss 2.4 and Oracle8!

 

This is the class you should use in the jboss.jcml file in JBoss 2.4 for DataSource creation , not the one mentioned by you:
org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl
Best,

Dragos
