Set JAVA_HOME & Tomcat

If u r familiar with tomcat you can probably help me. This is my deal I (from c:\jakarta-tomcat-3.2.3):
set JAVA_HOME=c:\jdk1.3.1
set TOMCAT_HOME=c:\jakarta-tomcat-3.2.3
and then bin\startup and it works fine, HOWEVER, when I try to open tomcat by from the actual startup.bat file in c:\jakarta-tomcat-3.2.3 by clicking on it I get a window that tells me, and I quote,
"You must set JAVA_HOME to point at your Java Development Kit installation"
Why do I get this message? Why am I able to startup from the prompt just fine, but not the way I just described(by actually going to the startup.bat file)?
Thank you to all the JAVA geeks...just kidding, I strive to be like u
Pedro

If you want the scripts to run by double clicking on them, you must set JAVA_HOME and TOMCAT_HOME permanantely in your autoexec.bat or you control panel. Setting them on the command line each time will not help. Try adding these lines to your autoexec.bat or the system program in the control panel:
set JAVA_HOME=c:\jdk1.3.1
set TOMCAT_HOME=c:\jakarta-tomcat-3.2.3

How to set JAVA_HOME programatically

Hi Friends,
Is there anyway to set JAVA_HOME environment property using a batch script.Actually,I am trying to check if the user system has java installed or not. If not,I make him run the JRE installer but the problem is when I try to start Tomcat, it expects JAVA_HOME to be set. So, I want to set JAVA_HOME programatically, is there anyway to do so???
This is the script i am using to check if java is already installed or not:
@echo off
::This batch file only tested under Windows 2000
::It will detect the short path of the current version
::of the Java runtime executable

::Find the current (most recent) Java version
start /w regedit /e reg1.txt "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment"
type reg1.txt | find "CurrentVersion" > reg2.txt

You are asking questions about Windows batch scripting in a Java forum?
When you get right down to it, the question is "How do I set an environment variable in a batch script", isn't it? Free your mind from useless distractions: the batch script and the operating system don't care at all what you're going to use that environment variable for.
Oh yeah, I almost forgot: you use the SET command to set an environment variable.

Setting java_home nd tomcat_home

Why to set JAVA_HOME and TOMCAT_HOME?

You set JAVA_HOME, i believe, so that Tomcat can access java from within its own scope. it has to launch process in the JVM since it is, itself, a java program. If the JAVA_HOME is not set, then it won't know how to access java otherwise. I think the TOMCAT_HOME is for it to know how to access its own web apps, for when it sets paths at launch, stuff like that.
Don't ask questions, just do it! it's all voodoo anyways...

How to set JAVA_HOME

Hi,
can any body tell how to set the JAVA_HOME variable for the
windows 95/98 operating system. Iam using the "jakarta-tomcat-3.2.1"
server for running the jsp files. I could do it in window NT os by setting up in the environment option of the mycomputer properties. I
couldn't know how to set it in the window 95/98 os
phani

To set the JAVA_HOME variable in Windows 95/98 you have to edit the file autoexec.bat located on your hard drive and add a line similar to this one.
SET JAVA_HOME=C:\J2SDK1.4.1
Where c:\j2sdk1.4.1 is the directory where java is installed.
Hope this helps.

How to set JAVA_HOME in REDHAT 9.0 Linux?

I was trying to set JAVA_HOME in profile file, but unable to decide where to put the java_home path. Can anyone guide me?
J2sdk and JRE are in /USR/JAVA

It is sufficient to set PATH.
In Unix (including Linux) most file systems are case-sensitive regarding the file and directory names. So /USR/JAVA is different from /usr/java.

P6v7 Web Services Oracle Universal Installer Error Setting Java_Home veriab

Hi,
I am installing Primavera P6 v7 web serivces on a Ms Windows 2003 SP2 server machine but it gives error "error setting Java_Home environment variable" every time i run the oracle universal installer setup of P6 v7 web services. I have already installed Java JRE1.6.0_14 and set the JAVA_HOME variables in both system and user variables. I have also tried manually setting path of JAVA during setup but no luck so far everytime same error. I have been looking at the log file in oracle inventory folder but did not find any hint to resolve the issue.
Please suggest a solution or workaround.
Regards,
Shahid

r u using 32bit or 64bit java?? better to use 32 bit java. Create 3 variable for EPPM P6
1) variable name: JAVA_HOME Value: c:\Java32\JRE1.6.0_27
2) variable name: JRE_Location value: c:\Java32\jdk.1.6.0_27\jre
3) variable name: p6_java_home value: c:\Java32\jdk.1.6.0_27

Setting java_home env variable

It looks like this java_home variable thing is gonna give me enaf trouble. Now I am sure i have done all as outlined in the release notes and cJDK_Users_Guide especially on "installation". There surely must be something wrong with my machine or jdk. Some body send me the full list of possible causes and suggested solutions.
Problem is in this institution nobody seems understand what I am talking about

First off, in your previous post, you provided your environment script:
@echo off
set jc_home = c:\java_card_kit-2_2_1
set java_home = c:\j2sdk1.4.1_07
Note that the spaces on either side of the equals sign are incorrect. The way you have it currently, the space is part of the key and value.
"java_home<space>" does not equal "java_home", likewise "<space>c:\j2sdk1.4.1_07" does not equal "c:\j2sdk1.4.1_07".
Remove the spaces and you will be OK.
"Problem is in this institution nobody seems understand what I am talking about"
Your problem seems to be related to your understanding of the windows command line - nothing to do with Java or Javacard.

Problems setting up Tomcat with RoboHelp Server V8

Hi,
My Systems Administrator is trying to set up RoboHelp Server version 8 for me. he has been following the Adobe Installation guide and has got as far as page 10 where it tells him to install and configure IIS and TomCat, at this point he says he does not understand what he should be doing. He has not installed TomCat before and it is telling him to configure the tomcat directory and although he has tried using what it says it comes up with an error the directory does not exist.
He is using:
Windows 2008 Server Standard
IIS 7.0
TomCat 6.0.20
SQL Server 2008 express SP1 - this is the latest version the adobe instructions says RooHelp Server works with SQL Server 2008 but does not mention express not sure if that could be a problem?
MS Report Viewer 2008 SP1
Java V6 Update 12
He says the installation guide talks about a directory with Win32 in it which does not appear on his machine its a 64 bit machine.
Please can someone give me some instructions on how to set up the TomCat part - I have looked but the troubleshooting that adobe has does not seem to be for Windows 2008 only Vista and XP and even then it says nothing about setting up TomCat
Thanks in advance

with best regardshello,
You did not set the variable JAVA_HOME. Set it to the home directory where the jdk is installed. For that give the command like set JAVA_HOME=C:\jdk1.3.1 in the DOS Prompt along with setting the J2EE_HOME and PATH variables...
you may also make a new system environment variable JAVA_HOME and assign the jdk home path to it so that u need not set it everytime for a new DOS Window..
hope that helps..

Setting java_home through java code

Hello , i went through lots of information for setting java_home through java code but i was unable to find any useful information, does anybody know how to set java home through java code

The question doesn't make any sense to me. If Java needs the JAVA_HOME variable set, how is it ever going to execute any code that does so? And if it doesn't need it, why set it?

Setting 'JAVA_HOME' in batch file

Hi,
I'am having a batch file for my Java application. I want to set the 'JAVA_HOME' variable if it is already not set.
I want to confirm if the following statement is correct or if there is a better way to do so.
if "%JAVA_HOME%"=="" set JAVA_HOME=c:\j2sdk1.4.1_02
Thanks in advance.
Regards,
Jay

You can also:
SET JAVA_HOME %JAVA_HOME%;C:\j2sdk1.4.1_02
That'll add the new pointer along with any others that are there already, if none exist then it will create the one pointer.
