title: How to find the application installed directory at runtime under websphere
body: <p>we are using WebSphere 7. WebSphere by default unpacked the installed ear application in to the
  directory "installedApps" for the given node, cell of application server. I am trying to find out the directory path for this installed directory in case that the default installed directory were not used.
  Does websphere provide any api that i can call from my applicaiton at runtime to find out the application installed directory?</p>
