POJO object representing execution details.
wfcontext for WLST Operation only works when using wlserver as WLST Script Folder.
Groovy and WLST scripts can invoke Java methods on variables supplied in environment. Here are the available methods for use by script based plugins. If method returns POJO object, other methods can be called to find specific value. For example, wfcontext.getCurrentInstance() returns Instance POJO, which provides additional methods like getInstance(), getName() and getCode() etc.
