http://www.tvparty.com/vaultcom2.html A white tornado tour of AJAX
The Plan Based on the card game, “Apples To Apples”, I explored AJAX and its ability to implement distributed computing. The short answer is AJAX is primarily useful within the Client/Server model of distributed computing
AJAX execution path
Interesting tangents HTML uses CSS AJAX uses JavaScript JavaScript uses DOM AJAX uses XML - System administration issues
- Development tools
AJAX execution path
HTML bumps & bruises Like any computer interaction, you must complete each tag’s braces These tags I really like: - (note, this tag can be obey width & height)
These attributes (of tags) I really like: - ID= to access html elements via script
- Size by px, %, em, ex
Suggested link. http://www.htmlcodetutorial.com Comments on the tools I used. - Macromedia Dreamweaver
- Linux Quanta
- Microsoft Frontpage
Source code onion soup JavaScript is embedded in HTML pages java.sun.com/developer/technicalArticles/J2EE/AJAX/index.html links to www.quirksmode.org/ as a good source of tips to keep JavaScript browser neutral
CSS cleans up HTML At its most simplistic level, CSS is a level of indirection. That indirection enhances consistency. - My favorite example, a collection of image tags can use the same style which specifies width & height
JavaScript JavaScript is not Java http://msdn.microsoft.com/library/default.asp?url=/library/en-us/script56/html/4af19f1b-1e9b-4116-beb6-6cde5d56947b.asp Mozilla.org has good JavaScript references Firefox has JavaScript console & DOM inspector Internet Explorer has JavaScript tools too, but I had previously neutered mine.
XML as seen in AJAX JavaScript may request XML from its server asynchronously from HTTP’s full page refresh cycle - XML can be inspected easy
- XML may be statically supplied
The server side of the world From Netbean’s quick starts, use a Servlet The power of Servlets The pain of Servlets - I’ve composed a nice webpage using a nice layout tool, how do I make a Servlet serve it?
Alternatives (at the server) - You may get closer “to the metal” – WHY?
- You may wrap much of the mechanical steps – Java Server Pages (JSP)
System administration comments - Netbeans -> Tomcat, change the ports to avoid conflict, configured in Server.xml
- Putty
- tunnel for home access "putty.exe" -ssh arch05.cis.gvsu.edu -L 5900:arch05.cis.gvsu.edu:5901 -L 9984:arch05.cis.gvsu.edu:9984
- VNC for remote access
System administration comments Why I feel good about using EOS. - I recognized Tomcat being used in an application at work.
- I believe, if it will work in “locked down” EOS, it’s a viable model for general deployment
- My development environment is accessible from several spots on the internet
Strange yet true developer.netscape.com seems to be a dead domain
