Thanks all for your valuable answers. I'm a WebSphere user, new to geronimo.
I'm migrating applications from websphere to geronimo. I thought I could
avoid modifying the code with
Context envContext = (Context)initContext.lookup("java:comp/env"); . I have
specified "jdbc/LiferayPool" for an example, not seeking help with liferay.

How do I connect to a datasource thru code without context "java:comp/env"
Context envContext = (Context)initContext.lookup("java:comp/env");
I just want to connect to DB like this
DataSource ds = (DataSource)initContext.lookup("jdbc/LiferayPool");
Is it possible, if so where do I specify java jndi context ("java:comp/env")
outside the code?
Thanks

Any such jndi name is going to be container specific. The java:comp/
stuff is there specifically so you can use the same jndi name in every
container, so you don't have to recompile your app for every container.
For information on the geronimo absolute jndi names, see
http://cwiki.apache.org/GMOxDOC21/jndi.html
Basically what you should do is deploy your datasource, restart
geronimo, and look in var/log/geronimo.log for the log message telling
you what the jndi location is.

As far as I understand what you are asking for in this sentence, it is
not possible.

What's your real purpose behind this (not specifying "java:comp/env")?
If it is just that you hate this string, you can use the "@Resource"
annotation to inject the datasource in container-managed artifacts (Servlet,
EJB, etc.).
@Resource (name="jdbc/LiferayPool")
private DataSource ds;

If I have not misunderstood you last question and although I am not a G
developer I hope no one minds I jump in an try to help out.
In Liferay there are several ways to set up a database connection but
you probably want to use Geronimo:s connection pool and sins Liferay
5.2.2 it is ones again possible to set up the application server
connection pools JNDI name by specify the following line in your
portal-ext.properties file.
###application server connection pools JNDI name
jdbc.default.jndi.name=jdbc/LiferayPool
I am not sure the following is required but I also have this in the end
of the web.xml file.
<!-- Geronimo usage -->
<resource-ref>
<res-ref-name>jdbc/LiferayPool</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
Hope this helps.
For more information about this take a look at
