Find a Java book from your favorite publishing company that has a chapter on Java Beans. Really, I'm not kidding, you can't write more than a chapter or two on the Java Bean Spec.
I'll give you the basics (which is like 90% of the spec :) You have to specify any init method that instantiates the object. You must have getXXX() and setXXX() methods that allow you to access the data within the object. Ok, there you go. You should be able to introspec the bean to list the getXXX and setXXX methods. There should be javadocs, or some other form of documentation with any half-decent third party product. As for integrating with CF: Instantiate the bean. Call the public methods on the bean. Want to know the other 10%? Beans exist because of Remote Method Invocation (RMI) EJBs are another sort of spec, much different than Java Beans. > I don't think most CF developers are going to care > to learn every Java concept to find out either, because then they > would be Java developers. Well, you're asking about a Java topic. And Java Beans is about .00001% of what Sun provides with the J2SE SDK. There's a TON of stuff that CFMX shields/hides/makes inaccessible from you. Trust me, you're not even close to being a "Java developer" just because you know what a Java Bean is. > -----Original Message----- > From: Jon Hall [mailto:[EMAIL PROTECTED]] > Sent: Wednesday, July 17, 2002 12:50 AM > To: CF-Talk > Subject: Re: MX and Javabean tutorials? > > > I just haven't had a reason to learn the Javabean concepts > beyond the basics until now, since we run Windows servers, I've always > been a COM guy, and Java was just an interesting learning experience, > and I'm still not interested beyond what I need to integrate with CF. > > I'm just interested in seeing a tutorial with a real world example how > I would integrate a Javabean that I bought in Jar format from > some company.
