Hi ,
I am using MyEclipse IDE for drawing UML Diagrams .
I can't find any difference between a abstract class and a normal class in UML .
Please let me know how can we identify an Abstract class in UML .

I should explain first that from the UML metamodel, isAbstract in an attribute of Classifier. Class extends Classifier.
The following is quoted from the UML 2.2 Superstructure specification:
The name of an abstract Classifier is shown in italics.

I did not understand what did you meant by the above line .Please tell me .
The name of an abstract Classifier is shown in italics.
Is this the only way to identify an abstract class ??

I was talking about UML metamodel, Class as a UML element extends from Classifier and Classifier contains Abstract attribute.

From what the specification mandates, yes. But if you want to make it more clear you can create "abstract" stereotype and apply to abstract classes.
