typical problem, pls help

[SATISH]

Hi all,



We have 3 systems pc25,pc24 and pc27........

pc25(the machine I am coding my pgms...)here I have IBM JDK
1.1.7 and also NetscapeLDAP client.....

AS I am using Netscpae LDAP I set the path to

path= C:\jdk1.1.7\bin\javac;C\netscape\server\bin;
classpath= C:\jdk1.1.7\lib\classes.zip;C\netscape\server\lib;

on pc27 we have the IBM websphere application server...to where I am deploying
all my files using IBMwebsphere studio on pc25...
here also I installed IBM jdk1.1.7 ans set the classpath...the same way as
for pc25.( here we dont have the LDAp server)

path= C:\jdk1.1.7\bin\javac.
classpath= C:\jdk1.1.7\lib\classes.zip.


on pc24 we have the LDAP server.
that is the environment.


Now I coded a simple PGM for LDAP authentication(on pc25)
and compiled that using the IBMwebsphere studio and deployed that on to pc27,,,,using
the tool.

In the PGM I am trying to access the valuesin LDAP server located on pc24..so
according to the syntax,,,I am using the IP address of PC24..in my PGM coded
on pc25 to link to the LDAP server. but I ma getting the error code below...Please
examine this carefully and if you know the answer please mail me asap....so
that I can proceed with the rest of my coding.

Kind Regards
Satish

[Fernando Ribeiro]

This is really due to problems in the setting of class paths. You should be
able to run your app in such a environment just by making sure the same classes
are available in the production server as well as in the development workstation.

Try do debug this code (even outside your production server) to make sure
that is not something you can solve by programming and not my configuring
the operating system, the VM, the paths, and all those things which are great
to take us a little bit away from our daily routine.

That is fun.
