jython script to add Web container > Custom properties

you can run below CMD to add prop for ALL JVMs:
./wsadmin.sh -f add_prop.py all prop_name prop_value

or add on one JVM with JVM name:
./wsadmin.sh -f add_prop.py my_jvm_name prop_name prop_value

Here is the code:

serverName = sys.argv[0]
propName = sys.argv[1]
propValue = sys.argv[2]

    else:
        tmpList = inStr.split("\n")
    for item in tmpList:
        item = item.rstrip();
        if (len(item)>0):
           outList.append(item)
    return outList
