Where Do I find the sources of dt.jar BeanInfo classes ?

Question

Hi all,
I would like to investigate the sources of the file dt.jar that is bundled with JDK ... I'm interested in the *BeanInfo classes that it has. Does someone know where can I find them ?
Thank you very much

Answer 1

There isn't such a class. BeanInfo instances are
generated for classes. Are you sure you understand
what BeanInfo is for? It describes a class, not an
instance of that classSo what's this (found inside of dt.jar) ?

}I think all gui designers find somewhere such BeanInfo information. I just want the sources of them without using some sort of decompilation .... I know the function of BeanInfo it describes a javabeans and its inherent properties ... PropertyEditor and so on .... I just want the sources
Thanks
