There is probably a solution to this problem to be found in the archives at sourceforge, but the search service has unfortunately not been available when I have tried to use it. I used to have this in my jboss.jcml file: <mbean code="org.jboss.jdbc.HypersonicDatabase" name="DefaultDomain:service=Hypersonic"> <attribute name="Port">1476</attribute> <attribute name="Silent">true</attribute> <attribute name="Database">default</attribute> <attribute name="Trace">false</attribute> </mbean> <mbean code="org.jboss.jdbc.XADataSourceLoader" name="DefaultDomain:service=XADataSource,name=DefaultDS"> <attribute name="PoolName">DefaultDS</attribute> <attribute name="URL">jdbc:HypersonicSQL:hsql://localhost:1476</attribute> . . </mbean> <mbean code="org.jboss.jdbc.XADataSourceLoader" name="DefaultDomain:service=XADataSource,name=OracleDB"> <attribute name="PoolName">OracleDB</attribute> <attribute name="DataSourceClass"> org.jboss.pool.jdbc.xa.wrapper.XADataSourceImpl</attribute> <attribute name="URL"> jdbc:oracle:thin:@myhost:1521:mydatabase</attribute> <attribute name="JDBCUser">myuser</attribute> <attribute name="Password">mypasswd</attribute> <attribute name="MaxSize">10</attribute> </mbean> I tried to lookup Oracle from an EJB with this call: DataSource ds = (javax.sql.DataSource) initCtx.lookup("java:comp/env/OracleDB"); and got a connection to Hypersonic (and no exceptions). Why? When i removed the two upper xml parts, i got the following error message when starting JBoss: [Container factory] Deploying mybean [Container factory] No resource manager found for OracleDB I have found no documentation on the upper xml part about Hypersonic. It seems like it have to be there, do I have to change it to make this work? What else is missing? I am quite new to JBoss, so I guess there might be an obvious reason why this does not work. -- Eli. _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
