You map these parameters and results to process variables. So you share information between nodes with the process variables. In the work item handler, you retrieve the parameters from workItem.getParameters(), and you put the results in the way you mentioned (.completeWorkItem). If you are in a gateway, you can access directly to a process variable by its name. (you can use it in a constraint for example).

This will get keys from the map, and put them into the process variable you have defined. Then, in a task node, you have to map each process variable you will need to a node variable. Then, when you are in work item handler, you will get the parameters you have defined for this node, not all process variables. To make it more clear. If you are using Eclipse plugin, 1) Define "examOK" variable in process. Click on process->Properties->Variables, and then add this variable 2) Then, for example you have a custom node. Click on the node->Properties->Parameter Mapping, and then you put the name of the process variable, "examOK", and the name you will use it inside work item handler (it can be the same). 3) Then, with workItem.getParameter("examOK") should work.
