Do not hard code the connection

Question

I trying to seperate the web container and ejb container into two machines
for an existing application.
It works in one machine, and it works on two machinese if I hard code the
JNDI factory, the provider_URL.
My question " Is it possible to do this without hardcoding the URL".
I am running two windows NT boxes for this.
thanks.

To use 2 different WL servers, one as EJB container and one as web
container, you have to create or edit your jndi.properties file (in your
jre/lib directory) and add two lines to it that specify
t3://<servername>:<port> ... unfortunately I don't have the information here
at home but I think that I have posted it before on one of these WL
newsgroups.

I may be missing it, but in this and another thread, I don't see where the
host is specified (where the EJB has been bound to a JNDI name)? I'vebeen
able to do this standalone using the -Djavax.naming.provider.url property.
However, I don't see how to tell an instance of a WL server that's just
running web-apps, where (on what machine) to find the JNDI tree that
contains the EJB Homes?
The code in this post seems to help when an EJB wants a simple way to get
it's own properties. I need to deploy the web-app and EJBs on separate
(non-clustered) systems.
Bottom line ... how to externalize the provider URL.
Thanks!

Here is an example:
Using 5.1.0 xml dd's, you can specify an <env-entry> which is
associated
with
your ejb:
<env-entry>
<env-entry-name>poolName</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
<env-entry-value>myPool</env-entry-value>
</env-entry>
file://now put this code into your Bean class
private String getPoolName( ) {
try {
// Obtain this enterprise bean's environment naming context.
Context initCtx = new InitialContext();
m_envCtx = (Context)initCtx.lookup("java:comp/env");
String poolName = (String) m_envCtx.lookup("poolName");
return poolName;
catch (Exception e) {}
return null;

You can put this info into your EJB deployment descriptors (xml if
5.1.0)
and
access them as environment variables.
