exporting variables

I have created and exported a variable.

Code:

export var=blah123

Now I want to access this variable by a java servlet running on a tomcat sever on the same machine.

Code:

System.getEnv("var")

But this keeps returning a null value. I have already searched the web but found the answers very confusing.

Has this java/tomcat process been started by the same shell in which you did the export? Unrelated processes don't obtain variable settings from each other.

no, it was not started by the same shell.
should I add this variable in a tomcat configuration file? if so, which file?
thanx for your help!

You certainly need to put it further up the same process tree or in a cfg file.
export only enables vars to be seen further down the same process tree.
