Tomcat 3.2 beta 4 bug?

[Willie Wheeler <ww...@andrew.cmu.edu>]

Hi all,

	I think that I've found a bug in Tomcat 3.2 beta 4.  In
PageContextImpl, the following bit of code appears in the
getAbsolutePathRelativeToContext() method:

  String uri = (String)
      request.getAttribute("javax.servlet.include.servlet_path");
  if (uri == null)
    uri = ((HttpServletRequest) request).getServletPath();
  String baseURI = uri.substring(0, uri.lastIndexOf('/'));

Problem is that the getAttribute() method on the request is returning a
URI that doesn't contain any / characters at all (at least, the servlet
path to the JSP that I'm using is just 'main.jsp', which means that the
uri.lastIndexOf('/') returns -1, and the call to substring() throws a
StringIndexOutOfBoundsException.

By the way, calling request.getServletPath() does in fact return a servlet
path that begins with a /, so I guess that something is setting
javax.servlet.include.servlet_path incorrectly.  It may help to know that
the StringIndexOutOfBounds is coming up during a jsp:forward (I am
forwarding to main.jsp, which is causing the exception), so maybe the
culprit is RequestDispatcherImpl?
