JSP & APPlet - HTML

Hi All,
I am new to web development platform. I know core java, now as I need to proceed to web development I would like to know certain concepts / languages used.
Jsp - Jsp is used to develop webpages, how does it differ from html.
Applets - We can develop web pages using applets. Then what are the circumstance we use applets, jsp.
JSP & Applets - Can JSP and Applet both used to create a webpage? If yes how?
Kindly answer my question. Thank you.
Regards,
lg

Go look up a basic tutorial dude.
Basically JSP lets you create an HTML page on the fly. Rather than just serving up a static page, you customise it for each request.
This gives a pretty good example of how JSP fits into things
http://www.javaranch.com/journal/200510/Journal200510.jsp#a1
Applets - Its a program running on a web page. I kinda lump them into the same box as "flash" and "activex". They let you step outside the bounds of html which a webpage is tied to. That has both advantages and disadvantages. Most web applications don't use applets.

Java applet was loaded in JSP as HTML.

I was running my web application in Linux platform. I have the lastest mozilla broswer which is 1.7.1. I was installed the Java plugins which this can be proved by i was able to load ICQ2Go of ICQ.com. The Java applet i created was loaded correctly in .html file. Unfortunately the Java applet was not load in .jsp file and a window was pop up to prompt me to go java.sun.com to donwload the proper plugin to view the applet which the link is http://java.sun.com/products/plugin/?application/x-java-applet;. I need help. Please give me a hand. Thank you.

JSP applet tag X Html applet tag (what is the difference?)

what is the advantage in using the JSP applet tag instead of a simple Html applet tag ?
second question:
I have an applet in a Html frame, and a menu on the left side.... When the user select the applet option at first time, everything runs ok.. after the user select another option and then select the applet again, it fails in some features .. Why ?

well, if by "the JSP applet tag", you mean the jsp:plugin tag.. that will just generate the same HTML tag you would write. The only advantage would be it should be less typing to use the taglib.
second answer:
without seeing any code, it'd be hard to figure out the problem. The obvious thing is you are setting some state of something that is preventing further action.

JSP, APPLET and JNLP

OK, here is my question, we have a simple (sic) application, which consists of jsps, applets ( Runtime.exec ), I have been suggested to use jnlp and jws, A typical JSP page looks like this.
<% %>
:Bunch of JSP /HTML stuff
<APPLET>
</APPLET>
Bunch of jsp/HTML/javascript stuff
How should i go about changing it to jsp + jnlp, Any insight is helpful.
Thanks.

Can i import java fx in jsp or html?

just to test i did rigt-click on my web-based jsp project project->new item->other->javaFX stage and wrote the example code like:

"web-based jsp project" => so you write JSP or HTML stuff there, no? Like including the dtfx.js file and putting the javafx({ ... }) call in the proper places.
"wrote the example code like (JavaFX code)" => Maybe it should be in a separate JavaFX project? Then generate the .jar file and use it in the above project.
Now maybe I am misleading (if there is a a JavaFX stage in new items of the projects, perhaps NB allows it?) so I hope somebody knowing NB better than me will help you.
Just in case: JavaFX code goes to .fx files; you cannot embed JFX code in JSP pages.

JSP Applet communication

Hi all ,
I know this question has been asked so many times and I have read all the posts but still i was unsuccessful.
I am trying to send a string from a jsp to another jsp which is loading the applet to display that string.
In my first jsp:
<form method=post action="hello.jsp">
<input type="text" name="formDesc" value="IBMTR/ABMTR Form" size="20" maxlength="20">
<input type=submit name="Go" class="submituttontext" value="Go">
</form>
in my seccond jsp:
<APPLET CODE="ParamTest.class" WIDTH="400" HEIGHT="50">
<PARAM NAME="font" VALUE="Dialog">
<PARAM NAME="size" VALUE="24">
<PARAM NAME="string" VALUE="Hello, world ... it's me. :)">
<PARAM NAME="formDesc" VALUE="<%=request.getParameter("formDesc");%>">
</APPLET>
in my applet:
String myFont = getParameter("font");
String myString = getParameter("string");
int mySize = Integer.parseInt(getParameter("size"));
String desc =getParameter("formDesc");
Font f = new Font(myFont, Font.BOLD, mySize);
g.setFont(f);
g.setColor(Color.red);
g.drawString(myString, 20, 20);
g.drawString(desc, 40, 40);
but nope i cannot see...formDesc ..I jus see the <%=getParameter%>
Thanx

At first glance the only error I see is:
<PARAM NAME="formDesc" VALUE="<%=request.getParameter("formDesc");%>">
should be changed to:
<PARAM NAME="formDesc" VALUE="<%=request.getParameter("formDesc") %>">
No semicolon in expressions. This should give you JSP compile error, so maybe that was just a typo in your post and not the real problem.
Let me know.

NetBeans or Forte is supposed to do that now. I've not had an occasion to try to do it in either yet though.

APPLET + HTML WORD DOC

I created a servlet class which would return a page ( applet + html ) to the client.
Now I want to create a URL link in this page, allowing the client to download this page to his computer.
How can I do this? Actually, the file can be of any type. The most important thing is that they can download it and save the page in their computers.
What do I need to accomplish this?
Thanks.

                   response.setContentType("application/octet-stream");
          String filename= "whatever you.like";
          response.setHeader
              ("Content-Disposition","attachment; filename=\""
               + filename + "\";"
               );And do not forget to use the outputstream (and not the writer).

Redirect from jsp bean to jsp or html page

I am facing a problem in redirecting to a jsp page from jsp bean
How do i redirect from jsp bean to any other page like jsp or html.
[email protected]

Hi
The solution you suggested we tried it long before only but it is not feasible for us as we have to implement it in all web pages which are in thousands.
My need is like this.
We have given specific time to each of our registered user , as user logs to our portal we calculate session time in bean and as he logs out is new time gets updated. (its like dial up connection)
Now what happens consider user has left only 10 minutes balance, I can calculate and keep track for his time in bean.Now as the time becomes zero I want to redirect him to home page.
As u said i can get return value zero for bean and can do it ,but our webpages are near about thousands.

Using java to get table rows (jsp and html)?

I was wondering if there is any way to count rows from a html-table?
I want to know the number of rows created, just after it has been made. So that I can use this number 'for' creating my next table.
Have got this to work by using javascript code:
          function test2()
               if (!document.getElementsByTagName || !document.createTextNode) return;
          rows = document.getElementById('spesifikasjonsTabell').getElementsByTagName('tbody')[0].getElementsByTagName('tr');
          antallRader = rows.length;
               document.test.hoyde.value = antallRader;
               return antallRader;
, but this only generates on the clientside; which is not what I want.
I got a webpage, that uses html and jsp. After the generation of a table - which has an unknown numbers of rows, because of several underlying tests - I'd like to retrive how many rows that was generated before I proceed with my next table.
Is there a good workaround to this problem?

Hey there, and thanks for fast response.
Allready tried that code earlier. Works great on displaying the var 'row'-s inside, for instance, a <input type="text" or as a pup-up on a alert();
The javascript works on the client-side, so I have no way of using that code for further testing in codes for my viewing; at least I can't think of any.
The thing is that:
1) I can't use an 'onClick', since the next table should be generated without any human interference.
2) I used the same code to get the number of rows when I sat the table inside a form. But then, when calling the javascript function, I have no way to retrieve the linenumbers for use to test ON the next table.
Since I'd have to use, say a field name <input type hidden="rows".., a method to call this very "rows" in jsp:
<table>

</table>
<%
int numberOfRows = request.Parameter("rowcount") or what ever; here is where I need the 'number of rows'
// let's just say int here though a String
if(numberOfRows < 35)
%>
<table>

</table>
<%
else
%>

<%
%>
Any ideas?
