All of a sudden, my Eclipse will not compile. I have been using it without any issue for months now making code changes, compiling and testing the change on localhost but suddenly it doesn't like me anymore. After I build my project, republish and restart the server I get the following.... Anyone ever seen this?

I saw the production environment was not found but, my java.library.path is: C:\Program Files\Java\jdk1.6.0_45\bin. When I run localhost I get the following error.

    Well it says it's started up... where are you seeing an error? – Jon Skeet Aug 06 '15 at 14:43
  • If the SetProperties is concerning you, see http://stackoverflow.com/questions/31854936 asked today too... – Jon Skeet Aug 06 '15 at 14:44
  • Seeing error when I try to pull open localhost webpage. Welcome.jsp should display. I edited my question to include the error messaging after trying to go to page – newguy Aug 06 '15 at 14:51
  • Right - that's more useful. It looks like the SetProperties part *might* be relevant... – Jon Skeet Aug 06 '15 at 14:52

Found a solution by simply deleting and recreating Server in Eclipse. Not sure how/why this worked, but it did. For future users, I also had to do the following:

  • Double-clicked Server to open Overview
  • Selected "Open Launch Configuration"
  • Under Arguments tab, I had 2 missing VM arguments that needed to be replaced after recreating server (-XX:MaxPermSize=1512m -XX:PermSize=512m)
