Appending the PATH

[Suttan Pym]

Hi,
I am using WAS5.1 and WASND5.1 cluster. I require a particular folder to be in the PATH. I have an ear deployed on WASND5.1 with target as cluster. Now the requirement is that this ear while execution requires to access some dlls in folder which is added in the PATH. I tried adding it in the system PATH attribute and also tried appending it to WAS_PATH. But it did not solve the problem.
Also, even if appending it to the system PATH would solve the problem, is there any way in the WebSphere where I could add PATH also, the same way as we have for adding jar files n the server CLASSPATH?
Thanks in advance,
Suttan
