Turning JavaCode into JBeans

That would help some people who do not know much about JavaBeans but want to turn their classes into beans.

All you need to do is to analyze a class and find out public fields, public accessor methods for them, and event information, all of which can be found using classes in java.lang.reflect package.

It would be nice if your application allow a user to create an icon and JavaHelp file for the bean as well.

Hi,

Some of information I posted in my previous reply were incorrect. In order to find properties, their accessors and events, you don't need java.lang.reflect package. (All you need is a BeanInfor class for an object.) Also, it seems that I didn't understand what you are trying to do.

Are you trying to create a BeanInfo class from a java source code?

If so, you probably have to parse the .java file and find all public field and methods (including accessors and event related methods), and construct XXXBeanInfo.java file.

If you are trying to create a BeanInfo class from a .class file, you can find properties, methods from its BeanInfo class, then create a source code for the BeanInfo class. (Sounds odd? - get a BeanInfo class in order to create a BeanInfo class.)

If creating a BeanInfo class is your objective, above two will do, but you might want to think why you want to do that because Java will create a default BeanInfo class if a class does not have one.

If you are trying to amend a .java file so that it satisfy the requirement of JavaBeans specification, that's a different story...

Well, then, you probably have to parse a .java file and analyze the code. Then, add necessary code to it (such as "null-constructor", get/set methods).
