Hello all,
The idea we had of building a screenscraper is to use the JTextArea functionalitie of Swing to render a GUI. The same the text area can render a web UI for HTML. The way the text area works is to have an Editor kit translate the bytes from a stream into document layout elements. Next is there a view factory that is able to render the text into a Swing text elements.
The package we added provides the editor kit and viewfactory to parse an incoming 5250 stream, translate it into Swing document elements which can be rendered by a EditorPane or something. By providing an simple alternative to the editor kit, you can 'interpret' certain areas in the stream and translate them into GUI constructs. This way you can change option fields into buttons, function keys into buttons, etc. If all of your screens conform to a certain company styleguide, you can augment these style to you own editor kit and parse out the title of the screen which you can apply to the window or dialog; you can drop options and functions and put them on the toolbar and/or menu etc. Then it becomes interesting. There is also a clipping editor kit to render partial 5250 screens to support windows etc. We have build a sprecific kits for one of our customers that is also customizable through XML to include icons for buttons after translating functions to toolbar buttons.
This makes it interesting. Not the most stable however at this point in time. Note you could use the editor kits in an web server to afterwards render the document elements as a webpage. Not sure though about resource consumption then.
Another very interesting class in there that is immediately usable for everybody is the Tn5250jTestTerminal.java class. This stats a 5250 session for a server but renders all screen planes on different tabs in the window. Very useful for debugging purposes !! I have used it to find out the workings of STRPCCMD. Try to use it to find out which bytes get send over on launching the PC cmd to verify if our implementation fails due to code pages etc.
HTH,
Wim

Hi all,
I am interested in the screen scrapping functions and what they can do
for my clients. Can someone give me a quick and dirty on how and what
this code does? Maybe an example of an application for this feature?
Thanks everyone and sorry for my ignorance on this.
