This section provides JavaScript samples.

• Starting a new process
  A new instance of a process can be started by using the tw.system.startProcessByName() function.
• Getting the current process instance
  The current process instance can be retrieved through the TWProcessInstance variable called tw.system.currentProcessInstance.
• Getting the current userid
  The current user ID can be retrieved through the TWUser variable in tw.system.user.
• Starting an external application
  

  You can start an external application such as a batch file or a shell script by performing that task using the JavaScript LiveScript mechanism.

• Returning the owner of a task
  

  You can know the identity of a user who has completed a given task.

• Returning a list of reference links
  

  You can return a list of all reference links of the current process application or toolkit on a server by running the tw.system.model.processApp.getLinks() method.

• Extracting a managed file
  

  If a process application or a toolkit contains a managed file, you can extract it from the runtime to evaluate its content.

• Search processes and tasks
  

  You can search a specific task in a current process.

• Calling Java through JavaScript
  JavaScript inside IBM BPM can invoke Java through the Live Connect technology.
