Description Sebastian von Knorring 2007-05-11 19:34:15 UTC
From the file RUNNING.txt I can read:

"Out of the box, Tomcat 5.5 requires the Java 2 Standard Edition Runtime
Environment (JRE) version 5.0 or later."

And later in the same file also:

Running With JRE 5.0 Or Later

(1) Download and Install the J2SE Runtime Environment (JRE)

(1.1) Download the Java 2 Standard Edition Runtime Environment (JRE),
      release version 5.0 or later, from http://java.sun.com/j2se.

(1.2) Install the JRE according to the instructions included with the

(1.3) Set an environment variable named JAVA_HOME to the pathname of
      the directory into which you installed the JRE, e.g. c:\j2sdk5.0
      or /usr/local/java/j2sdk5.0.

So a JRE should be enough, although the path examples at step 1.3 mention JDK
installation paths.

However, when using the installed JRE and setting the value of JAVA_HOME to its'
path "C:\Program Files\Java\jre1.5.0_11", when I run bin\startup.bat I get the

The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE

So, as a matter of fact I need indeed a JDK although the docs state the
contrary. :-/

Actually, A JRE is fine but running text is wrong.

If you are using a JRE you need to set JRE_HOME rather than JAVA_HOME. The docs
have been updated in svn and will be included in the next release.
