Hi there,
I', trying now for hours and days to get this done. Perhaps somebody
could help me out of my trouble. I am using JBoss 2.2.0 FINAL and a
Oracle 8.1.7 DataSource. When I try to lookup the DataSource within my
Bean (BMP Entity Bean) I get the following Exception:
[Account] TRANSACTION ROLLBACK EXCEPTION:null; nested exception is:
javax.ejb.EJBException

The code I am using within my bean to lookup the DataSource is the
following:
private Connection getConnection()
throws SQLException
{
InitialContext ctx = null;
try {
ctx = new InitialContext();
DataSource ds = (javax.sql.DataSource)
ctx.lookup("java:/comp/env/jdbc/MyPool");
return ds.getConnection();
} catch (NamingException ne) {
throw new SQLException(ne.getMessage());
}
}
My jboss.jcml looks like this:
[...]
<!-- JDBC -->
<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=comp/env/jdbc/MyPool">
<attribute name="PoolName">comp/env/jdbc/MyPool</attribute>
<attribute
name="DataSourceClass">oracle.jdbc.xa.client.OracleXADataSource</attribute>
<attribute
name="URL">jdbc:oracle:thin:@myhost:1521:instance</attribute>
<attribute name="JDBCUser">user</attribute>
<attribute name="Password">pass</attribute>
</mbean>
[...]
And here I have my ejb-jar.xml and my jboss.xml:
<ejb-jar>
<enterprise-beans>
<entity>
<display-name>Account</display-name>
<ejb-name>Account</ejb-name>
<home>mycomponent.ejb.AccountHome</home>
<remote>mycomponent.ejb.Account</remote>
<ejb-class>mycomponent.ejb.AccountBean</ejb-class>
<persistence-type>Bean</persistence-type>
<prim-key-class>mycomponent.ejb.AccountPK</prim-key-class>
<reentrant>False</reentrant>
<resource-ref>
<res-ref-name>jdbc/MyPool</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</entity>
</enterprise-beans>
</ejb-jar>
<jboss>
<enterprise-beans>
<entity>
<ejb-name>Account</ejb-name>
<jndi-name>Account</jndi-name>
</entity>
</enterprise-beans>
<resource-managers>
<resource-manager res-class="org.jboss.ejb.deployment.JDBCResource">
<res-name>jdbc/MyPool</res-name>
<res-jndi-name>java:/comp/env/jdbc/MyPool</res-jndi-name>
</resource-manager>
</resource-managers>
</jboss>
And when the Server starts, everthing seems to be ok (at least in my
eyes):
[JDBC provider] Initializing
[JDBC provider] Loaded JDBC-driver:oracle.jdbc.driver.OracleDriver
[JDBC provider] Initialized
[comp/env/jdbc/MyPool] Initializing
[comp/env/jdbc/MyPool] Initialized
[...]
[JDBC provider] Starting
[JDBC provider] Started
[comp/env/jdbc/MyPool] Starting
[comp/env/jdbc/MyPool] XA Connection pool comp/env/jdbc/MyPool bound to
java:/comp/env/jdbc/MyPool
[comp/env/jdbc/MyPool] Started
So what do I miss????
Any help or ideas for me?
Thanks in advance!
Ralf
