Java Database Connectivity (JDBC)

Hi all,

I'm usins a cloudscape XML like the following :

<?xml version=1.0" encoding="UTF-8"?>

<server>
	<mbean code="org.jboss.resource.connectionmanager.LocalTxConnectionManager" name="jboss.jca:service=LocalTxCM,name=CloudscapeDataSource">
	<depends optional-attribute-name="ManagedConnectionFactoryName">
		<mbean code="org.jboss.resource.connectionmanager.RARDeployment" name="jboss.jca:service=LocalTxDS,name=CloudscapeDataSource">
			<attribute name="JndiName">jdbc/CloudscapeDB</attribute>
			<attribute name="ManagedConnectionFactoryProperties">
			
				<properties>
					<config-property-name="ConnectionURL" type="java.lang.String">jdbc:rmi://127.0.0.1:1088/jdbc:cloudscape:CloudscapeDB;create=true</config-property>
					<config-property-name="UserName" type="java.lang.String></config-property>
					<config-property-name="Password" type="java.lang.String></config-property>
				</properties>
			</attribute>
			
			<depends optional-attribute-name="OldRarDeployment">jboss.jca:service=RARDeployment,name=JBoss LocalTransaction JDBC Wrapper</depends>
		</mbean>
	</depends>
	
	<depends optional-attribute-name="ManagedConnectionPool">
	
		<mbean code="org.jboss.resource.connectionmanager.JBossManagedConnectionPool" name="jboss.jca:service=LocalTxPool,name=CloudscapeDataSource">

			<attribute name="MinSize">3</attribute>
			<attribute name="MaxSize">10</attribute>
			<attribute name="BlockingTimeoutMillis">5000</attribute>
			<attribute name="IdleTimeoutMinutes">15</attribute>
			<attribute name="Criteria">ByContainer</attribute>
		</mbean>
	</depends>
	
	<depends optional-attribute-name="CachedConnectionManager">jboss.jca:service=CachedConnectionManager</depends>
	<attribute name="TransactionManager">java:/TransactionManager</attribute>
	
	<depends>jboss.jca:service=RARDeployer</depends>
	</mbean>
</server>

My problem is that I don't know what to set as the lookup parameter in :

DataSource ds =  (DataSource) context.lookup("what_to_set_here");

Plus, I've tried connecting by Class.forName, il works fine. But I'd like to solve that DataSource stuff...

Thanks for any help
