Hello,

I have seen this question asked several times and each time the
suggestion is to make sure that tools.jar is in the classpath. It
looks like I _do_ have tools.jar in the classpath and I am still having
the problem. Can anyone suggest a solution? I'm on NT Workstation
using JDK 1.2.1. Here's the output of the problem -- it happens as
soon as I click on the link for the JSP.

C:\jakarta-tomcat\bin>echo %PATH%

As they suggested earlier make tools.jar in your CLASSPATH!!!
As far as i can see it isnt!!
Type:
set CLASSPATH=%CLASSPATH%:%JAVA_HOME%/lib/tools.jar;
before you start tomcat...
also some other things... in your PATH, there's a c:\jdk1.2.2 , but
JAVA_HOME points to c:\jdk1.2.1
Both these should be the same jdk1.x
(also , upgrade to v1.3 ;)

Are you *sure* you're using jdk1.2.1? Your path contains c:\jdk1.2.2\bin
- make sure the environment variables match reality and have another go.
