title: Java security policy file question
body: <p>Okay guys, I am trying to get the interpreter to use my .policy file for some JAAS stuff I am doing.  When I try to enter the extra entry <strong>(ie. policy.url.3=file:/C:/Test/raypolicy
  )</strong>  in my <strong>Windows:java.home\lib\security\java.security</strong> 
  file, it refuses to save the new entry.  I get a <strong><em>Save not successuful</em></strong> prompt telling me to make sure that the program is not open in somewhere else. Of course, it is not open somewhere else.  </p>
  
  <p>I know that it is a wrong setting somewhere on my computer as I am able to save to my java security file on my computer at work.  I am running a Windows 7 on my personal computer and a windows xp at work. I have also already checked the file settings for the security file and I am set up as the administrator so I have authority to change the file, etc.  Any and all thoughts are welcome.</p>
