Java Security

Hi All

Please suggest on how to run a openssl command from a java program.

I am using this

Runtime runtime = Runtime.getRuntime();
runtime.exec("openssl pkcs8 -inform der -nocrypt test.der result.pem");

This is suppose to take test.der as input and create result.pem.

There are no errors but the file result.pem isnt created.

Thanks in Advance
