Hot Deploy with Eclipse & Tomcat throwing ServletException

I've had it working and then made some style changes and it seemed to stop (<- might be a red herring). The file /hv/header.jsp hasn't moved and eclipse can still find it.

I shortened the stack track but can paste the entire one.

i think you have a tag like note the ' char in the file name... this is probably the cause.

I fixed this by making a new workspace.
