Hi Roshan,
The dynamic properties would first have to be added to the bean's EClass. Then you would
access the dynamic properties using EMF's reflective methods, eGet() and eSet(). So for
instance if you added a property "Street"...note that you would first have to
model this as an EAttribute, and then add the EAttribute to the EClass, ...anyways,
assuming you added it...you would then get the property on an instance of the EClass like
this:
someObject.eGet("Street");
The general sequence is to create a EClass.
Add EReferences (Representing references) and EAttributes (Representing
primitive properties...non object references).
Create an instance of the EClass. someObject = EFactory.create(myEClass);
Then later if you need to add primitive properties, you just add more
EAttributes to the EClass and then create another instance. Now the instance
will have these properties, and you can set and get them using eGet and eSet.
Tuscany Service Data Objects work in a similar way.
Cheers,
- Ole

Thanks!
The article looks great.
I just tried the code, but it doesn't seem to generate getters and
setters dynamically, which seem to be needed by the JavaBeans
Introspector to recognize properties.

Hi Roshan,
I just happened to see this, and the JavaBeans Introspector stuff is
completely new to me. However both Eclipse EMF beans / modeled classes
and Apache Tuscany SDO (Service Data Objects) support adding properties
dynamically. There's a really good article on how to do it using EMF
here:

Sorry I could not give you a more direct answer.
Cheers,

Hi,
I didn't see this on the User Guide, but is it possible to add dynamic
properties to a JavaBean and have the JavaBeans Introspector pick it
up?
For example, if I have an Object Temporary, and at runtime, I want to
add properties (getter and setter methods) to it, then use the
Introspector class to get these dynamic properties, is that possible?
