Re: indirect jndi lookup of resource

Thanks for your reply, that helped.  I had a little trouble figuring out
how the reference was actually bound to the datasource.  I used the
web-xml editor in WDSc and added the jndi binding under the 'WebSphere
Binding' tab, but couldn't see it when I looked at the source of
web-xml.  When I ran the app the first time, I got a "A reference to an
ResourceRef" exception.  A search on google found a developerWorks post
mentioning multiple bindings in ibm-web-bnd.xmi.   I checked in my .xmi
file and there were multiple entries there.  Removing them fixed the
problem and all my warning message are gone.

Hi,
This page in the documentation explains the error message and
deprecation:
http://publib.boulder.ibm.com/infocenter/wsdoc400/topic/com.ibm.websphere.iseries.doc/info/ae/ae/rdat_jnditips.html?resultof=%22%64%69%72%65%63%74%22%20%22%6c%6f%6f%6b%75%70%22%20

This page has a short description looking up a datasources relational
DB
access and short example:
http://publib.boulder.ibm.com/infocenter/wsdoc400/topic/com.ibm.websphere.iseries.doc/info/ae/ae/cdat_datsorres.html?resultof=%22%64%61%74%61%73%6f%75%72%63%65%22%20%22%64%61%74%61%73%6f%75%72%63%22%20%22%6c%6f%6f%6b%75%70%22%20
  The page has some appropriate related resource links at the bottom
too I
think.

Here is an example from the documentation of using the indirect lookup

How do I use an indirect jndi lookup of a datasource?  WAS 6 server
gives a warning that direct JNDI lookups are depreciated and I should
be
using indirect lookups.  I tried the following code and still get the
warning.  Is there something I need to set up in the WAS server, like
a
Connection Factory?  The code works, just gets the warning message in
the server logs.  The word 'indirect' tells me that I shouldn't be
using
the datasource name in the application code, but I can't figure out
the
correct code.

web-xml:

<resource-ref>
     <res-ref-name>jdbc/myds</res-ref-name>
     <res-type>javax.sql.DataSource</res-type>
     <res-auth>Application</res-auth>
     <res-sharing-scope>Shareable</res-sharing-scope>
  </resource-ref>

application code:
   InitialContext ctx = new InitialContext();
   ds = (DataSource)ctx.lookup("java:comp/env/jdbc/myds");
