Problem with fresh installation: "Unable to find a javac compiler"

[Bert Catsburg <be...@catsburg.com>]

Hello Tomcat experts,

I have a problem with getting the installation to work.
First an overview of my installation:
JAVA_HOME = C:\j2sdk1.4.1_01\
Tomcat is installed in C:\jakarta-tomcat-4.1.18-LE-jdk14\

When starting tomcat (http://127.0.0.1:8080/index.jsp)
I get the following error in the stderr.log file:

   Unable to find a javac compiler;
   com.sun.tools.javac.Main is not on the classpath.
   Perhaps JAVA_HOME does not point to the JDK

I searched this list and all other resources and I cannot
find any reference to this problem.

Anybody can help me? Please?
Thanks,

Bert Catsburg

Ravi,
thanks for your prompt answer.

At the command prompt I type 'javac' and get a response from the
compiler. So, javac is found.
I do not understand why I should add %java_home%\bin to the
classpath. First, I read somewhere that I do not need a classpath
(although I do have a classpath variable pointing to the %java_home%\lib
directory). Second, the bin directory does not contain jar or class
files.

Hope somebody can point me to other possible solutions.

Thanks,

Bert Catsburg

Your %JAVA HOME% is not set correctly.  Check to see if you can run
the compiler at the command prompt...ie
 type JAVAC at the c:\ prompt if it says external command it means the
JAVA_HOME is not set correctly..

to set it correctly you need to add the JAVA_HOME to your SYSTEM
PROPS->Environment to point to the correct directory.  You may also need
to add the %JAVA_HOME%\bin to your class path ie you can specify the class
path as c:\jdk X X X\bin;

Hope this helps
Ravi
