jbpm4.4,how to get property from custom activity in jPDL(xml)
================
<custom id="Act_2" name="myCustomTask" class="com.meadlai.CustomActivity" point="309,70" memo="">
<property name="form"><string value="99801"/></property>
<property name="mark"><string value=""/></property>
<property name="model"><string value="2"/></property>
</custom>
===============
I know I can get property "model" in the class:"com.meadlai.CustomActivity" by coding:
public class CustomActivity{
private String model; //getter & setter to get the property
private String mark;
...
execute(){...}
...
}
===============
but, I need to get it in another way, just with taskName.
EnvironmentImpl environment = ((ProcessEngineImpl) processEngine).openEnvironment();
try{
ProcessDefinitionImpl pdf = execution.getProcessDefinition();
ActivityImpl activity = pdf.getActivity(taskName);
if ("custom".equals(activity.getType())) {
Object model= activity.getProperty("model");
System.out.println("model = "+ model);
}
}catch(Exception ex){
}finally{
environment.close();
}
==============
sadly, I got "null" with this manner.
Could you please give me some clue? I am a newer.
Thanks very mcuh.
