I'll try to address a few things that are implied by your use of wsadmin. I may be overshooting, but I hope this helps:
WSADMIN applies only to the full WebSphere Application Server. jython scripting for the Liberty profile is possible, though you're basically performing JMX operations on a server. Here is something to get started with: https://www.ibmdw.net/wasdev/docs/creating-remote-jmx-connections-with-jython/
There is no way to reconfigure a Liberty profile server via a JMX operation, however. All server configuration (or reconfiguration) is done by editing the server configuration file (either manually with an editor of your choice, via the eclipse tools, or with a script that modifies your XML).
The Liberty profile does not support CORBA or CORBA namespaces (corbaloc or corbaname), or remote EJBs. Liberty profile servers also are not part of the cell/node topology of full profile servers. Instead, Liberty profile servers form collectives, as described here:

You can add strings to JNDI using the jndiEntry element in your server configuration as described here: http://pic.dhe.ibm.com/infocenter/wasinfo/v8r5/topic/com.ibm.websphere.wlp.core.doc/ae/twlp_dep_jndi.html
Information about configuring datasources (I am guessing at what you might need URLs and namespace bindings for) is here (see also the subtopics): http://pic.dhe.ibm.com/infocenter/wasinfo/v8r5/topic/com.ibm.websphere.wlp.core.doc/ae/twlp_dep_configuring_ds.html.
