Now I'm getting a NoClassDefFoundException when I try
to run my echo JSP:
sun.tools.javac.Main
(It used to work.)
I see that this class is contained in my
JAVA_HOME/lib/tools.jar. I also see from a Google
search that lots of folks have had problems with this.
The easy fix is to modify the CLASSPATH, but where to
do it?
I'm running Tomcat 4.0.6 as a Windows service. A
Google search turned up a script that showed me how to
do it:
@echo off
if "%OS%"=="Windows_NT" setlocal
set SERVICE_NAME=Apache-Tomcat-4.0.6
set JAVA_HOME=C:\Tools\JDKs
set
TOMCAT_HOME=C:\Tools\jakarta-tomcat-4.0.6-LE-jdk14
set
BOOTSTRAP_SERVICE=org.apache.catalina.startup.BootstrapService
set STDOUT=%TOMCAT_HOME%\logs\stdout.log
set STDERR=%TOMCAT_HOME%\logs\stderr.log
echo Service name: %SERVICE_NAME%
echo Java HOME : %JAVA_HOME%
echo Tomcat HOME : %TOMCAT_HOME%
echo Bootstrap : %BOOTSTRAP_SERVICE%
echo Output log : %STDOUT%
echo Error log : %STDERR%
tomcat.exe -install %SERVICE_NAME%
%JAVA_HOME%\jre\bin\client\jvm.dll -server -Xms64m
-Xmx256m
-Djava.class.path=%TOMCAT_HOME%\bin\bootstrap.jar
-Dcatalina.home=%TOMCAT_HOME%
-Djava.endorsed.dirs=%TOMCAT_HOME%\common\endorsed
-start %BOOTSTRAP_SERVICE% -params start -stop
%BOOTSTRAP_SERVICE% -params stop -out %STDOUT% -err
%STDERR%
if "%OS%"=="Windows_NT" endlocal
But now that I examine that script a little more
closely, I see that I don't have any -classpath
arguments passed to the tomcat.exe. Typing tomcat
-help didn't reveal any CLASSPATH info.
Why isn't Tomcat picking up my tools.jar anymore?
This gets worse by the minute! I knew how to run
Tomcat this morning! ;) - MOD
