Answering my own question:
I solved this by creating my own custom rules.
1. I created a class StatusCheckRule which is mapped to the
*/a:response/a:propstat/a:status path. In this class I check the content of the
status element and if contains "200 OK" I push a Boolean object with a given
name (digester.push("myName", obj)) to the digester stack with the value true.
2. I created a class MyProjObjectCreateRule which is mapped to the
*/a:response/a:propstat/a:status path. In the begin() method I check if the
statusFlag has been set to true and if it has I create my Appointment object
and push it to the stack. In the end() method I call a method (the method name
is passed in the constructor of MyProjObjectCreateRule) on my parent class by
using MethodUtils (similar to how it's done in SetNextRule).
Everything works fine and I have no problems with setting attributes on my
object etc. My new question is if this is good approach or could I have solved
differently?
Thanks in advance
