Environment Variable

I am working on a server.
How do I check that jre is set in PATH or CLASSPATH variable ?
Can jre be set in JAVA_HOME variable or any other variable ?

thanks

JAVA_HOME may be used as part of PATH.
The JRE might be in something like /usr/bin, as a .so file, otherwise it ought to be in PATH.
You might not have anything in CLASSPATH. Try echo (on Bash)
[Campbell@queeg ~]$ echo $PATH
/usr/java/jdk1.6.0_11/bin/:/usr/java/jdk1.6.0_11/bin/:/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/Campbell/bin
[Campbell@queeg ~]$ echo $CLASSPATH

[Campbell@queeg ~]$ echo $JAVA_HOME

[Campbell@queeg ~]$
Note I have nothing set as JAVA_HOME or CLASSPATH. I think on Windows you write PATH at a command line.

Is that any help to you?

In windows as well, try typing the classpath in the command prompt:

In the Tomcat servlet container, the console explicitly logs in the environment variables included in the java library path logged at INFO level during the startup.

Does it mean that when we're starting the tomcat service the environment variables path and classpath will be displayed at the [INFO] tags.

Its necessarily the INFO message for Tomcat Native library (tcnative-1.dll) which is optional. The list of libraries added to your PATH are displayed right ahead.
