Weblogic WLST classpath

Question

When I run the WLST .sh script to set the env as follows why can't I see the updated path when I do echo?

[linbox2 bin]$ ./setWLSEnv.sh 
CLASSPATH=/directory/ols_wls/patch_wlss1032/profiles/default/sys_manifest_classpath/weblogic_patch.jar:

Your environment has been set.
[linbox2 bin]$ export CLASSPATH 
[linbox2 bin]$ export PATH 
[linbox2 bin]$ echo 
$PATH

Answer 1

This is because you are executing this script. This means that a new shell process is being created, and the variables defined or modified have a scope only in that subshell. The parent process does not inherit child's environment.

Whenever you want to load an variables defined in a given file, you have to source it:

$ source file

or

$ . file

Answer 2

You can either copy the CLASSPATH=.... until the end and then into a terminal do

export CLASSPATH=...

Or you can just do the following into a terminal

eval `./setWLSEnv.sh ` # this will set into your environment the CLASSPATH

You can check your environment by doing this

env |grep CLASSPATH # look if it matches on what the ./setWLSEnv.sh sets
