Problem while staring the Tomcat 7.0.37 ?

Hi All,
I have below configurations in my system.
Jdk1.6
Jre 1.7
below system variables are set :
JRE_HOME = C:\Program Files\Java\jre7;
JAVA_HOME = C:\Program Files\Java\jdk1.6.0_37;
CATALINA_HOME = D:\JAVA_2\apache-tomcat-7.0.37;

when trying to start the tomcat using below command by going to the bin folder of apache :

D:\JAVA_2\apache-tomcat-7.0.37\bin>startup
The JRE_HOME environment variable is not defined correctly
This environment variable is needed to run this program

tried to set the path for jre_home but still the error exists.

In my system, I have two program files folders
1. C:\Program Files (x86)
2. C:\Program Files
are these the problem for the above message ?

Thanks,
Datta

Why are you attempting to use two completely different versions of Java at the same time?

You do not need to set JRE_HOME. JAVA_HOME is sufficient.

i had tried using single environmnet variable JAVA_HOME still it was throwing the error.

Can you please guide me.

In that case, I suspect that the environment variables are not set for the execution context that you are trying to run Tomcat in.

In the command window where you issue the Tomcat "startup.bat" command, issue this command:

In order for Tomcat to launch properly, that command should have printed a value that points to a valid Java JDK.

Hi,

I have checked it.
there is no environmnet variable "JDK_HOME".
should I define it.

all you need is JAVA_HOME set correctly,
and you can't really mix and match different versions of JRE / JDK,
and I'm not sure why you're trying this.

Do you planning to run tomcat that will run under java 6 and 7 at the same time?
this is not possible.

add:

echo %JAVA_HOME%

to your startup.bat
and execute it, make sure it shows you correct path.

Sorry, I mis-typed it. Should have been "echo %JAVA_HOME%".
