Re: JNDI Context Lookup Help
Hi Mark,
I had similar problems with Geronimo 2.1.
You can check out my simple method for traversing JNDI:
private void traverse(Context ctx, String path) throws NamingException {
// lists all contents of current context
NamingEnumerationBinding ne = ctx.listBindings();
while (ne.hasMore()) {
Binding b = ne.next();
String name = path + / + b.getName();
// if current object is a context, traverse it
if (b.getObject() instanceof Context) {
traverse((Context) b.getObject(), name);
}
// otherwise print out object's name and its class
else {
logger.debug(name + == + b.getClassName());
}
}
}
invoke it like this:
Context c = new InitialContext();
traverse(c, java:comp/env);

hope it helps :)

Hi All,
It's been a while since I had to ask for help from the list, but I hit a
snag migrating an application from G-1.1.1 to G-2.1.3. Specifically,
I'm having a problem with a JNDI context lookup inside a
ServletContextListener. I presume this is a problem with the move to a
global JNDI namespace in G-1.2 and forward. I have had the same result
in 1.2-beta and 2.1.3. The Documentation and Google have not helped me
here.
I'm looking up an env-entry defined in the web.xml:
env-entry
env-entry-nameweb/ContentLocation/env-entry-name
env-entry-typejava.lang.String/env-entry-type
env-entry-value/SomeDirectoryHeirarchyName//env-entry-value
/env-entry
Access code as follows:
String contentLocation = null;
String contentLocationJNDIName = java:/comp/env/web/ContentLocation;
Context ctx = null;
boolean initialContextSuccess = false;
try {
ctx = new InitialContext();
initialContextSuccess = true;
} catch (NamingException namingException){
namingException.printStackTrace();
}
if(initialContextSuccess){
try{
contentLocation = (String) ctx.lookup(contentLocationJNDIName);
} catch(NamingException namingException){
namingException.printStackTrace();
}
} else{
// Error Handling
}
The ctx.lookup() throws a javax.naming.NotContextException:
comp/env/web/ContentLocation.
Do I need to define Properties for the InitialContext Factory, add
something to my geronimo-web.xml plan, or utilize a different JNDI name?
Thanks for your help,

RE: JNDI Context Lookup Help
Thanks! You must have been reading my mind about just dumping the whole
JNDI name space to find the proper name.
Question: Why did my code work in 1.1.1 with the slash after comp:/,
should it have? Just curious about it.
Is there a documentation area on migrating between Geronimo versions
that a note about this could be added for future reference by others?
Probably another thread here, but I'll drop this in anyway:
It was fairly simple to change my deployment descriptors and get my EAR
to run in G 2.1.3.
I had to modify my geronimo-application.xml (application-1.1 to
application-2.0), and my openejb-jar.xml (openejb-jar-2.1 to
openejb-jar-2.2) for the new name space definition, but my
geronimo-web.xml worked without changing the the namespace from 1.1 to
1.2. I was pleasantly surprised to have my EJB 2.1 beans deploy as
smoothly as they have. Once again, is there any documentation
discussing this?
I migrated a couple of Database Pool and Security Realm deployment plans
with the project, but would have to go back and look at them to identify
any differences.
Also, any gotchas when combining EJB 2.1 and EJB 3.0 components in the
same EAR. I plan on utilizing EJB 3.0 moving forward without migrating
my existing session and entity beans from 2.1 any time soon.
Hope this helps others in the future
Mark

Re: JNDI Context Lookup Help
Shouldn't your name be java:comp/env/web/ContentLocation (no slash
before the comp)?
thanks

RE: JNDI Context Lookup Help
Thanks David, Worked like a charm! Guess G got a little more precise
after 1.1.1:) It's been wrong for the last year, G-1.1.1 must have been
more forgiving. I bet my definition in geronimo-web.xml was wrong.
