[Jython-users] JythonServlet with 2.1 container

[Kent J. <kjo...@tr...>]

I am trying out PyServlet using Jetty 2, a web server that implements 
the 2.1 servlet spec, and I have a little problem.

The value of request.getServletPath() is different in 2.1 and 2.2 in 
a way that breaks PyServlet. Under 2.1, when the servlet is matched 
by an extension match, getServletPath() returns null. Under 2.2, it 
returns the entire path through the matched extension.

The Servlet 2.1 spec says,

public String getServletPath();
[snip]
If the servlet was invoked by some other mechanism than by a path 
match (such as
an extension match), then this method returns null.

whereas the 2.2 spec has the example

Servlet Mapping Pattern: *.jsp
Servlet: JSPServlet
/catalog/help/feedback.jsp ContextPath: /catalog
ServletPath: /help/feedback.jsp
PathInfo: null

To make PyServlet work with Jetty I changed line 108 to read
   spath = ((HttpServletRequest) req).getServletPath() + 
((HttpServletRequest) req).getPathInfo();

i think this will work under both 2.1 and 2.2, though I have not 
tested it with 2.2.

Thanks! PyServlet is cool!
