Tanks for the reply, First of all I'm not implying that it is a OJB bug since the Introspector is within the Sun's JDK but would the few lines be to harsh in performance and thus could not be integrated since I think that e.g.
--> setresembleValue is not equally readable as (in code perspecive, not e.g ide managed environments) --> setResembleValue and thus gets more readable code. I won't challenge the java community with that and can accept such convention but I think latter method name for retrieving the property is far easer to read... I just thought it was method names started with non capital letter in the sentence e.g. removeAll, addTail and thus properties always begins with UC letter since getter and setter is prepended e.g. setMachineConfig, getId....

The Introspector and PropertyDescriptor are part of the JDK, not classes specific to OJB. I haven't got the JavaBean spec to hand, so I cannot categorically confirm that it is part of the JavaBean spec; however it is definitely a convention (widely adhered to) that the member variable of a property has a lower case first character. It is a little more complicated when both the the first letter and second letter are upper case - you'd have to read up on beans the Sun site. However, I can definitely confirm that this behaviour is not a bug.
