----------------------------------------------------------

you have to make sure you have JDK and well as SDK environment installed in your pc..
then... edit the autoexec.bat file.. with the following commands,
change which ever directory that applies..

set TOMCAT_HOME=c:\tomcat
set JAVA_HOME=c:\jdk1.3

path=%path%;c:\jdk1.3\bin;c:\jdk1.3\lib
SET PATH=%TOMCAT_HOME%\bin;%PATH%
set CLASSPATH=c:\jdk1.3\lib\tools.jar;%CLASSPATH%

set classpath=c:\tomcat\lib\webserver.jar;c:\tomcat\lib\jasper.jar;c:\tomcat\lib\servlet.jar
-----------------------------------------------------------
wheer can i edit to make the changes above as i cant seem to find an auotexec.bat file i dnt have JDK insatlled only J2re 1.4.2_05 and j2re 1.4.2_06 in the folder C:\Program Files\Java\j2re1.4.2_06

how do i amke cnges so that i can view jsp on my openwave sim?? PLease help i am very confused!!

Thanks guys xx

as for me, you just need to install java, tomcat,
and set the environment variables that you say...
TOMCAT_HOME
JAVA_HOME
path=%path%;c:\jdk1.3\bin;c:\jdk1.3\lib
PATH
CLASSPATH
classpath=c:\tomcat\lib\webserver.jar;c:\tomcat\lib\jasper.jar;c:\tomcat\lib\servlet.jar



(you can do it :right clic in My Computer if you re in Windows,properties.
then advanced options, there it is
first try to get it in IExplorer before checking in openwave-
if it work in IE, check your WML code, it is very sensitive.
Good luck

there are no current envrionemnt variables, so do i need to create new variables with the above paths etc you suggested??

sorry i have never configured a server before, hence the 101 questions
