Normally, web technologies can be devided to client side and server side. From you experience, "Basic Html, Css, And Php"I think you canClient side: javascript or vbscript. Applet is optional.Server side: Get familiar with some PHP framework, such as PHPNuke, etc. MysqlThen I think you'd better to know some general applications, such as credit card payment application, authenticate and authorization, etc.

"then makes an update within frame B" I'm not sure what's the meaning of this. I suppose it may be page reload or text change. Anyway, you need define a event processor for it. In the event processor, use top.frame[0] to reference frame A to load another page. But there are a limitation, the page in frame A and frame B should be from the same domain. The security in IE forbid access between frames from different domain. If so, you need reload the whole window. The server return a new frame set and frames. From the user view, there is no much difference to the previous solution.

The effort spending to fully understand java script depends on your understanding of DHTML, DOM, Java concept. I suggest you reading the book "JavaScript: The Definitive Guide" published by O'Reilly This is all you need to learn javascript. If you'd like to know some tricks for coding, then you can start "Javascript & DHMTL Cookbook" published by O'Reilly There's no good book to learn the practical DOM. It is a very important part for you to code javascript. What I'm doing is read the DHTML reference of MSDN from Microsoft. When coding, keep it open is important.

From my experience, java script can call applet and applet can call java script, but it is better don't mix these two technology in your web site. In my previous project, call from applet to java script may cause ie in windows xp home version dead lock, although all the other version work fine, including windows 98, windows 2000, windows xp professional. So I believe the support of java in microsoft is not critical. You can play it, but don't consider it in your job.

JSP is a combination of HTML and Java. I suppose you are professional to HTML and new to Java. Of course you may not. To start with JSP, actually you need learn Java first. 1 you can read these topics in Java Tutorial http://docs.oracle.com/javase/tutorial/index.html Getting Started Learning the Java Language Essential Java Classes Collections JavaBeans JDBC Database Access These are enough for you to start JSP. 2 JSP is based on servlet, actually JSP is translated to SERVLET before it is executed. Of course, learn servlet is not a must to start JSP. Just let you know their relationship. Here is a good place to start. http://www.jguru.com/ Then you can code JSP, but you can code does not mean you know how to code correctly. The following help you understand JavaServer Pages Model 2 architecture http://www.javaworld.com/ 3 Then you try to install Tomcat and try to run http://www.javaworld.com/ To know how to deploy your application. A long term work. :-)

If you system is linux, you can use cron job to do the same thing. It is a tool to start specified program at specified time continuouly. You can use crontab -l to show the existing cron job. You can also use crontab -e to configure it. the job definition can be divided into two part. One part is the time schedule definition. You can specify the year/month/day/weekday/hour/minute/second. One part is program definition. It is same as your command line, such as java -jar run.jar.

As I know the java script is client technology rather than server technology. It is supported by the browser running on client. Server technology include JSP/SERVLET, EJB etc., they are actually part of the J2EE solutions. So java script server is actually not exist in the world.
