If there really is a way to to streamline that, it would be great. The main point, is that scraping is an option where the the data and code are difficult to separate.<br /><br />http://idevnews.com/PrintVersion.asp?ID=161Hank Ratzesbergerhttp://idevnews.com/PrintVersion.asp?ID=161noreply@blogger.comtag:blogger.com,1999:blog-6819462794293857673.post-1953018974217911872005-04-04T20:13:51.000-07:002005-04-04T20:13:51.000-07:00, which uses the same principle and must create a ..., which uses the same principle and must create a new version every so often, when eBay changes the layout of it's pages. If you can, you're better off creating a SOAP or REST interface to your legacy apps, than just to depend on HTML views of your data.

If you really need to interact with the application, you would need to be able to post forms as well.Erik Brucheznoreply@blogger.comtag:blogger.com,1999:blog-6819462794293857673.post-2296284646755960612005-04-04T02:12:13.000-07:002005-04-04T02:12:13.000-07:00Erik, you're too modern!

Screen Scraping is actually an acceptable way to create an interface to a legacy app. I can't find the information on the IBM team working on this, but an example of pushing AS400 green screens to the web via scraping:<br />http://www.jacada.com/Products/Legacy_Extension.htm . It was a way of putting an interface on a legacy app while you re-architected it, but I'm not sure that once companies created a thin client layer, they had a lot of incentive to rewrite the application in, say Websphere.Hank Ratzesbergerhttp://nees.ucsb.edunoreply@blogger.com
