Java Programming

for some reason my curl command does not run when I run it from within my java program and errors out with "https protocol not supported". This same curl command however runs fine from any directory on my red hat linux system.

To debug the problem, I printed my curl command from the java program before calling Runtime.getRuntime.exec command and then used this o/p to run from the command line and it runs fine.

I am not using libcurl or anything else, I am running a simple curl command as a command line utility from inside a Java program.

Any ideas on why this might be happening?
