error NoInitialContextException - why ?
i am receiving this error when i run my app from AIX
java.lang.Exception: An exception occurred in Metrics
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
I run the same code in WIN with the same dir structure and it works fine and logs to my Metrics log and DB
but when I push the jar to AIX I get the error however it logs to my metrics log just not the DB?
is there something else i need to do for an AIX environment setup..
my jndi.properties looks like this
java.naming.factory.initial=com.sun.jndi.fscontext.RefFSContextFactory
java.naming.provider.url=file:////systemapp//appFolder
where my jndi.properties are stored
can anyone make a suggestion on what i need to do?
thanks in advance

The jndi.properties is probably not in the classpath.
this is the .sh file i use to start the app
cd /sysapp/appFolder
CLASSPATH=/usr/java130/jre/lib/rt.jar

and i have the jndi.jar there am i missing something else
The jndi.properties! Where is it placed? Is it in a directory included in the classpath?
the jndi.properties is located in this dir/sysapp/appFolderdir
yes the jndi.properties is in the classpath now -and i still get the errordo i need to put the jndi.properties in the CLASSPATH?
> the jndi.properties is located in this dir> > /sysapp/appFolder> > dirI don't see that included in the classpath. It seems to be the working directory but then your classpath does not include a dot -- "."
> do i need to put the jndi.properties in the> CLASSPATH?Yes, and the classpath has to be the classpath of the server, not the system classpath. By the way, is it a stand-alone application or a serverside application?
i just added /sysapp/appFolderto the class path and reran the app and it still gave me the errorwhat '.' dot do i need?
> what '.' dot do i need?never mind the dot for now. post the code where this exception is generated.

i dont have the code where it breaks b/c its a commonhelp.jar that breaks and i dont have access to that code i just include it to my appthe commonhelper.jar works b/c i have used it in prior apps and it works and logs and tothe DB - im just confused on this one
thx for the link - i will read over that and see what i can get out of it - i will post again shortly and see if it helps me resolve the issue :)
i got it! thanks - i typo when i added the new line to the class pathi had/sysapp/appFodlerinstead of /sysapp/appFolderhowever i typed it right when i put it on the board - THANKS! CHEERS
btw - the link was useful too !

Hmm, good! I was beginning to think that I don't know anything about J2EE.
I'm new to JNDI and I was trying to set up a JDBC Connection Pool with JNDI according to the example illustrated here: http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html
When I tried the JDBC via Connection Pool , on the Command Line I got this error too:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file
After scratching my head for a long time, I figured... hmm JNDI is set inside Tomcat's server.xml Context - so by running a JNDI example from the command line , how will my small application see what's in Tomcat's server.xml ?
The only way I was able to fix this error was to run my JDBC JNDI test from inside a web application in Tomcat.
If I tried to run the example independent of Tomcat it wouldn't work !
D'uh :-)
