Fixed error of gridsphere not loading

With Marlon's help, fixed the problem of getting to the Gridsphere login page, and seeing this error message:

GridSphere portal failed to initialize!

Unable to create portlet web application: portlets-driver Stack Trace:
Unable to create portlet web application: portlets-driver Caused by: Unable to load portlets from: portlets-driver + due to mapping error!

Problem was that I had run the command: mvn install from the "portlets" directory and not the root directory of the OGCE installation. So remember to always run mvn install or mvn compile from the top-most directory.
