You should be able to create new instances of classes with default constructor with .newInstance(); At leas I am:
Class clazz = Class.forName("my.new.dumped.Clazz");
Object o = clazz.newInstance();
(you have to catch some exceptions here);
Do not forget that you class must have no-arg constructor:
package my.new.dumped;
calss Clazz {
Clazz() {//it is enough;}
//something else
}Two pieces of advise from me:
1. When generating classes, make them implementing some interfaces, or extending appropriate class. Thus you may:
SomeInterface si = (SomeInterface)clazz.newInstance();
and invoke methods without reflection;
2. While in development, run the verifier on your dumped classes. Most probably your JVM verifier has much less comprehensive output than JustICE: the bcel's verifier. An easy way to run it is:
org.apache.bcel.Verifier.main(new String[]{"my.new.dumped.Clazz"));
Hope this Helps Cheffo

Hi, I m stuck up in creating the new instance of classes. Using BCEL i created a class and have written the same onto the file system. I am able to execute the Class.forName for the file but not able to create a new instance using class.newInstance(). I checked the mailing list for creating the instance, but still not able to figure it out exactly.
IF you could please guide me for the same.
