Exception initializing servlet

Any takers on this one?

I'm getting the following error initializing a servlet:


=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
type Exception report

message Internal Server Error

description The server encountered an internal error (Internal Server
Error) that prevented it from fulfilling this request.

exception

The Tomcat example servlets work OK.


My overriding loadConfiguration method looks like this (it's worked for
other servlets):

  protected Properties loadConfiguration(ServletConfig config) 
  throws IOException, FileNotFoundException {
    Properties p = new Properties();

    ServletContext ctx = config.getServletContext();
    String relativePath = "/WEB-INF/templates/";
    String realPath = ctx.getRealPath(relativePath);
    p.setProperty( Velocity.FILE_RESOURCE_LOADER_PATH,  realPath );
    p.setProperty( "runtime.log", realPath + "/velocity.log" );
    p.setProperty( "velocimacro.context.localscope", "true");
    p.setProperty(
	"velocimacro.permissions.allow.inline.to.replace.global", 
        "true");
    return p;
  }
  


Thanks
