Weird init param problem on linux/apache/jserv1

[Vincent Schonau <vinces@xs4all.nl>]

I've been having a weird problem installing GNUJSP on my system. Relevant
clues: Linux 2.2.0, Blackdown JDK1.1.7; Server: Apache/1.3.3 (Unix)
ApacheJServ/1.0b1 mod_ssl/2.0.14 SSLeay/0.9.0b; latest GNUJSP.

jserv.properties has the correct classpaths. The zone properties file has:

servlet.jsp.code=JSPServlet

and

servlet.jsp.initArgs=classfiles=/home/httpd/jsp

However, when I attempt to access a .jsp page, the mod_jserv log sais:

 (ERROR) ajp11: Servlet Error: Initialization error while loading the
servlet: no compiler.classpath init parameter specified

I've tried lots of things so far, but the only thing that works is setting

servlets.default.initArgs=classfiles=/home/httpd/jsp

- and it'll work. In other words: for some reason,  JSPServlet won't get
it's own initArgs.

Where should I start looking for a solution to this?

Thnx,

Vince.
