Java Forum / General / November 2005New to JSP world
Hi all, I'm new to jsp and xml. I don't expect anyone to code my solution for me but I have NO IDEA which way to go to learn what I need to know in order to get this done. I bought a few books which have helped but I'm basically stuck. I have some background in programming (ASP, VB) but I'm having a rough go at getting started with jsp. In the last week I've managed to install the J2SE, Tomcat and Tomcat connector on a Win 2000 server running IIS 5. Now the task I have at hand is this. I have a simple form. Call it form #1 which contains a textfield for an e-mail address and a submit button. I use form #1 to connect to a db2 database via a supplied java based API that was written by my company. This API then returns some XML about the person attached to that e-mail address. If the e-mail address is not found I need to redirect to an eror page. If the e-mail address IS found in the database, I need to strip out just the e-mail address, put it into some kind of variable and redirect the user to another form (Form #2) populating the e-mail field in Form #2 with that same e-mail address. What techniques should I be looking into to learn what I need to know? If it were php and mySql I could have had the project finished in the length of time ot took me to write this post lol. Thanks All! : Hi all, [snip] : I have : a simple form.

I assume you need to write the form-action handler to process the submit button action. In that case, you have two options: 1. Servlet 2. Scriptlet I personally prefer Servlet over Scriptlet because I want to keep java code separate from the jsp. .K > I assume you need to write the form-action handler to process the submit button action. In that > case, you have two options: > > 1. Servlet That was my thinking. The form #1 is housed here on our server and the API is housed on another server which I have no access to. All I get back is some XML relating to the person in a string. How do I pull the e-mail out of XML and back into my JSP. Or simply, let JSP know that this persons e-mail exsists in the db? : > I assume you need to write the form-action handler to process the submit button action.

If you know the tag element of the email address, you can parse/filter the xml stream to pull it out. .K >basically stuck.

JSP and servlets are not that complicated. The hardest part is not barfing at the ugly syntax. See http://mindprod.com/jgloss/jsp.html Marty Hall is one of the best Java writers around. He has three books out on the topic.

And though nothing suffices in stead of a book for learning at the beginning, he does have tutorials on the web also. >bravo.

I always imagined Marty Hall as a white haired professor with a slight English accent. I had communicated with him many times over the years in email. I saw a picture of him a month or so ago. He is quite young and looks like a football player. Similarly I imagined Dimitry Leskov at Jet/Excelsior to be tall thin, Mr. Burns clone, bald about 65, looking like Professor Leimanis, my advanced algebra prof at UBC. He too is a young "sprout".

And I'm no spring chicken, either. I've had two observations about being, or trying to be, a super programmer: 1) I think it could make your neck thin :) no offense meant to anybody, but I do tend to live too cerebrally, when concentrating so much on these things 2) you generally start to lose command of language. Programmers (generally) are not good at spelling or grammar. I think I'm pretty good at language. But if I have an intensive job where I code all day, no chitchat, nothing other than problem solving, I start to lose that. E.g., my fingers will type out "their" when I damn know well it's "they're". >>bravo. I always liked the way that he explained the "why"of things, >>rather than just relaying or describing knowledge.

Not so me. I might get a bit that way when I'm tired, drunk or just plain hurried, but in general, I'm damned proud of my communication skills.
