I am having problem in setting CLASSPATH variable through my perl script such that it will work both on Windows and Solaris. On Solaris I can use export CLASSPATH=/mypath/ and execute it through the backtick operator. But this does not work on my windows2000 machine. Is there a better way to do this ? The CLASSPATH variable is required to be set by my perl script since it executes java code using backtick operators and requires the CLASSPATH to be set. Thanks!
