overriding default JNDI context for a datasource

[malyg]

Is there a way to deploy a datasouce without the VM context "java:/"

I am trying do deploy a data source in JBoss 3.2.0 under a jndi-name - "jdbc/MyDatasource", however JBoss deploys it under "java:/jdbc/MyDatasource". The documentation says that it does it because a datasource should only be available for a particular VM and therefore only belongs to that VM's context.
In my case, however, the datasource name has to be "jdbc/MyDatasource" - without the context part.( The reason - I am deploying to an Weblogic production instance that has a datasource named "jdbc/MyDatasource" and have to way of changing this, and would like to have dev. evironment to be exacly the same).
Thank you for any advice on this really frustrating matter.

Use reference to look up DataSource and you dont need to care about deploy JNDI name.

J2EE
<!-- JDBC DataSources (java:comp/env/jdbc) -->
<resource-ref>
My Data Source
<res-ref-name>jdbc/MyDatasource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

WEBLOGIC
<resource-description>
<res-ref-name>jdbc/MyDatasource</res-ref-name>
<jndi-name>yourDeployName</jndi-name>
</resource-description>

JBOSS
<resource-ref>
<res-ref-name>jdbc/MyDatasource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<jndi-name>yourDeployName</jndi-name>
</resource-ref>

Source (works on WL and JBOSS) :
Context ctx = new InitialContext();
DataSource ds = (DataSource)initial.lookup("java:comp/env/jdbc/MyDatasource");

Thanks micke, that works!

Also it seems that JBoss deploys the same datasource
under "java:comp/evn/jdbc/MyDatasource", which works in my case since Weblogic also deployed the datasouce under that name.

So, from what I've seen one can say that:

If you deploy a datasource with a name "jdbc/MyDatasouce" it can be located under the following names.

In Jboss - under "java:/jdbc/MyDatasouce" or under "java:comp/env/jdbc/MyDatasource"

In Weblogic - under "jdbc/MyDatasource" and "java:comp/env/jdbc/MyDatasouce"

Note: "java:comp/env" is the J2EE "recomended" component evrionement context, as far as I understand.

Never mind the last post. JBoss did not deploy my datasource under "java:comp/env".

micke's solution seems to be the only one that works
in my case.

My appologies.
