JNDI with Datasources and multiple applications

[UweBritfeld]

This may sound remedial but I'm running into a problem.

I've got a Websphere 4.0 server with both an IT and a DEV environment on it. I've created two Applications, one for DEV and one for IT.

I have a datasource for each: jndi/DBDev and jndi/DBIT.

As I move my code from Dev to IT, when I look up the datasource via JNDI, I don't want to have to change my ctx.lookup() when I change environments.

i.e.
ds = (DataSource)ctx.lookup("jdbc/DBDev" in dev and
ds = (DataSource)ctx.lookup("jdbc/DBIT" in IT.

My understanding is that I can accomplish this by creating entries in web.xml and ibm-web-bnd.xmi but it isn't working for me.

Here's what I have in web.xml:
<resource-ref id=&quot;ResourceRef_1&quot;>
<res-ref-name>DB/Chrome</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

In ibm-web-bnd.xmi in DEV I Have:
<resRefBindings xmi:id=&quot;ResourceRefBinding_1&quot; jndiName=&quot;jdbc/DBDev&quot;>
<bindingResourceRef href=&quot;WEB-INF/web.xml#ResourceRef_1&quot;/>
</resRefBindings>

And in ibm-web-bnd.xmi in IT I Have:
<resRefBindings xmi:id=&quot;ResourceRefBinding_1&quot; jndiName=&quot;jdbc/DBIT&quot;>
<bindingResourceRef href=&quot;WEB-INF/web.xml#ResourceRef_1&quot;/>
</resRefBindings>

I thought I could then do a lookup in JNDI for &quot;DB/Chrome&quot; in either environment and wind up pointing at the proper Datasource.

My problem is that JNDI can't find &quot;DB/Chrome&quot; at all. If I do the lookup on &quot;jdbc/DBIT&quot; or &quot;jdbc/DBDev&quot; it works fine.

My only other option is to specify the datasource name using a parameter.

Has anyone tried this, or am I way out in left field?
