title: Can't Save "Is a Tomcat Project" setting in Eclipse Project Properties
body: <p>I have a Spring MVC project that I've been deploying to Tomcat (installed both locally and on a server).  I'm using Eclipse Indigo as my IDE.  To deploy, I had been right clicking and choosing "run on server", which would run fine on localhost.  For deploying a WAR to the actual server, I had been right clicking on Project, selecting Export, and going through the wizard to deploy a WAR file.  </p>
  
  <p>My Eclipse/Java is rusty, but I did remember that when I used it a couple of years back, I was using the Sysdeo plugin for Tomcat that would give me an option for Deploy to War right from the right click context.  So, I poked around and found "Mongrel", which I installed.  With that in place, I went to Mongrel under preferences, and set up my Tomcat version, so that I can click the little start/stop Tomcat icons and start/stop the server.  This was successful.</p>
  
  <p>What I can't now do for the life of me is, in Project Properties->Tomcat, choose "Is a Tomcat Project".  I check the checkbox and then click Apply and/or OK to dismiss the window, and when I open it again, my setting is not recorded.  I have tried checking the box and adding other options (like context name, path for a WAR file export, root sub-directory, and activating dev loader), but nothing I do "sticks".</p>
  
  <p>Can someone tell me what I'm missing, or at least point me in the right direction?  I'm stumped.</p>
  
  <p>Thanks in advance.</p>
