Classpath - Weblogic Server

Question

Hi All,
I'm pretty new to Oracle SOA and Weblogic server getting myself familiarize with some POCs .
I'm a bit lost with setting CLASSPATH in Weblogic server . Require your help in the following.
1) If i want to use some third party JARS for JDBC connections, where can i set this classpath ? Tried to set the CLASSPATH / Pre pend ClassPath and Append to Classpath from Admin console. But it didn't work .
I had to modify the setDomainEnv.cmd file, add it to the POST_CLASSPATH variable and then it did work. My question is why is it not being reflected when i have added it from admin console.
2) I have a Java application wherein it reads a properties file from classpath. Tried setting the same from admin console,as expected didn't work.
Then i had to modify commEnv.cmd file in WLS_HOME/common/bin folder and then it did worked ... So can't we set these from admin console ?
Please do help me with the above and thanks in advance.
Regards,
Sri

"Once you update the classpath from the admin console, how can you start the admin server with the node manager?"
To start the admin server by using the node manager, you can use WLST, for example,
bea_home = '/home/oracle/soa/domains';
pathseparator = '/';
admin_username = 'username';
admin_password = 'password';
listen_address = 'localhost';
listen_port = '5556';
admin_server_url='t3://localhost:7001'
node_manager_home = bea_home + pathseparator + domain_name + pathseparator + 'nodemanager';
domain_name = 'soa_domain';
domain_home = bea_home + pathseparator + domain_name;
print 'START NODE MANAGER
startNodeManager(verbose='true', NodeManagerHome=node_manager_home, ListenPort=listen_port, ListenAddress=listen_address);
print 'CONNECT TO NODE MANAGER';
nmConnect(admin_username, admin_password, listen_address, listen_port, domain_name, domain_home, 'ssl');
print 'START ADMIN SERVER';
nmStart('AdminServer');
