Using Java-Framework's inside Jabaco
There are millions 
of Frameworks based on Java. Jabaco is based on Java too - so it is very simple to use every Java-Library with Jabaco. You could use Frameworks like Hibernate, Java3D, eFace, ... Let's go.
I'll show you how to use the Java XML-Lib. I have googled for Java XML and found javax.xml.parsers.DocumentBuilderFactory. That sounds good and so i have a look to http://java.sun.com/j2se/1.4.2/docs/api/…derFactory.html
Ok, this Class is abstract and have a static method "newInstance()". This is a singleton pattern (don't know what that is? Have a look to http://en.wikipedia.org/wiki/Singleton_pattern). There are some syntax-differents from Java to Jabaco. For Jabaco you have to replace the "." to "#" in the namespace.
Now we should have a new Instance of the document factory and could create a DocumentBuilder (http://java.sun.com/j2se/1.4.2/docs/api/…entBuilder.html). There is the next interesting method "parse()" which returns a instance that is compatible to the "org.w3c.dom.document"-interface (http://java.sun.com/j2se/1.4.2/docs/api/…m/Document.html). That's what we want:
