Since WebLogic removed "ServiceConfigurationMBean" from WLST in 11g, writing a Python script as you normally do was out of the question. Using Java was the only possibility at this stage, but it felt a bit much writing a new app just for a simple task like this.
This is when a college pointed me to https://github.com/nearinfinity/node-java which is a module to write native Java which is then executed inside your javascript using Node.js.
It turned out to be very straight forward and I added a sample JavaScript here: https://gist.github.com/dunse/5122258
In order to run the script, you will need Node.js, Java and some WebLogic libraries.
The WebLogic libraries been specified in the getbs.js file as:
java.classpath.push('configfwk-1.1.0.0.jar'); java.classpath.push('sb-kernel-impl-1.1.3.0.jar'); java.classpath.push('sb-kernel-api-3.0.jar'); java.classpath.push('sb-kernel-common-1.1.3.0.jar'); java.classpath.push('wlfullclient-10.3.0.jar'); java.classpath.push('standalone_client-11.1.1.jar');Copy those files to the current working directory and update any version numbers as necessary.
Next, define your connection options:
var config = { admin_server: { "hostname": "z2esbadmin01.zst.optusnet.com.au", "port": 9001, "username": "weblogic", "password": "w3blogic" } };
And then run it:
node getbs.js
If all goes well, it will output something similar to this:
qwerty/business_services/qwerty_bs => http://my.backend.server.com:8080/EndPoint/
