JSP error with standard Javac (and a workaround) with Tomcat 4.1.27

[Chris Brown <br...@reflexe.fr>]

Hi,

I've just upgraded from Tomcat 4.1.24 to 4.1.27, and am using the default
out-of-the-box configuration (see below).  Tomcat now refuses to compile
JSPs with the default settings.  I need to modify conf/web.xml such that the
"fork" init-param for the JSP servlet is set to "true" (not "false", which
is the default)... and then it works.

Basically, without "fork=true", it complains that it can't resolve
JAVA_HOME.  When it forks, all goes well.  See the output below for more
information.

Here's my config:

- Win2000 SP4 (no other web servers running/installed)
- Sun's J2SE 1.4.2 SDK, installed in d:\java\jdk1.4.2
- JAVA_HOME is set as a system environment variable,
  pointing to d:\java\jdk1.4.2
- "tools.jar" is in the "lib" subdirectory of JAVA_HOME.
- Tomcat 4.1.27, downloaded as a binary release from main
  website http://jakarta.apache.org/tomcat/

Hope this helps iron out a wee problem!

- Chris B.
