Você possue o Java SDK instalado?
Se sim a você deve setar JAVA_HOME com o path que Java SDK está instalado.
Se não, então você precisa fazer download do SDK e setar a JAVA_HOME com o path que Java SDK está instalado.
leonardom,
eu irei apenas rodar uma aplicação, portanto, só precisarei do jre. Pelo que eu sei, o jsdk só é necessário para desenvolvimento.
Por favor me corrija se eu estiver errado.
Respondendo a sua pergunta, não tenho o jsdk instalado.
Cara, parece que o Tomcat necessita da JSDK para funcionar, não tenho muita certeza (Alguém me corrija se estiver errado).
Running The Tomcat 4.0 Servlet/JSP Container
============================================
This subproject contains Tomcat 4.0, a server that implements the Servlet 2.3
and JSP 1.2 Specifications from Java Software. In order to install and run
this container, you must do the following:
(0) Download and Install a Java Development Kit
Download a Java Development Kit (JDK) release (version 1.2 or later) from:
Install the JDK according to the instructions included with the release.
Set an environment variable JAVA_HOME to the pathname of the directory
into which you installed the JDK release.
(1) Download and Install the Tomcat 4.0 Binary Distribution
NOTE: As an alternative to downloading a binary distribution, you can create
your own from the Tomcat source repository, as described in “BUILDING.txt”.
If you do this, the value to use for “${catalina.home}” will be the “dist”
subdirectory of your source distribution.
On a Windows platform, you will need:
jakarta-tomcat-4.0-YYYYMMDD.zip
On a Unix platform, you will need:
jakarta-tomcat-4.0-YYYYMMDD.zip
Unpack the binary distribution into a convenient location so that the
distribution resides in its own directory (conventionally named
“jakarta-tomcat-4.0”). For the purposes of the remainder of this document,
the symbolic name “${catalina.home}” is used to refer to the full
pathname of the release directory.
