[Advanced-java] Another odd question - how to convert String to literal?

[xwang@xxxxxxxxxxxxxxxxx (Alvin Wang)]

Hi! Thanks for those helping me with my odd question. Maybe they are naive.
Here is another one.

I serialized an MyClass object into byte[], and then put the byte[] into
database, along with the class name "MyClass" as String. Later on, another
program looks up the databaase, and picks up the byte[] and the class name
"MyClass". It will deserialize byte[] into Object obj. However, I do not
know how to convert obj to be a MyClass object. That means I do not know how
to convert String "MyClass" to java language class name literal of MyClass.
I do not think Reflection will help, because I am not building a new MyClass
object.

Can any guru help me out? Thanks!
