Use awt to display histogram in a JSP?!

Hi,
I have been searching the web in the area awt and JSP and it feels like I am fumbling in the dark. I want to display a histogram, which shall be updated continuously from a database. I have found a program example, which is creating a histogram using awt. This example is using a frame and my question is, could I import this frame to my JSP or is there a way to make use of the awt class in a JSP and display, draw the histogram directly in my JSP page?
Thanks in advance!

The only way to use AWT in a JSP would be to put the
AWT in a applet and put the applet in the JSP.

Can I use AWT elements in a JSP, and so could I generate events with them?

This is because I�m doing a simple JSP that showing a button, my JSP is:
<html>
<%@ page import="java.awt.*" %>
<%! Button b = new Button("Hola!!!"); %>
<% add(b); %>
</html>
But when I tried to see the button in the browser, my JSP generates the following:
Compilation of '/RAID5/weblogic/myserver/classfiles/jsp_servlet/_gep/_alterno/_23_mayo/__mr4.java' failed:
/RAID5/weblogic/myserver/classfiles/jsp_servlet/_gep/_alterno/_23_mayo/__mr4.java:79: cannot resolve symbol
probably occurred due to an error in /gep/alterno/23_mayo/mr4.jsp line 7:
<% add(b); %>
Could somebody help me please?.....
Can I use AWT elements in a JSP, and so could I generate events with them?
Thanks!!!

There are 2 ways to run a web page dynamically:
1) Reload the page via use of javascript or some other scripting language.
2) Use an applet to regularly check a URL for the data
Remember, as Paul pointed out, JSP's only generate HTML output. AWT components need to run inside a JVM not a just the browser.
I could recommend an applet but you may have problems with IE6 not supporting java. Otherwise there shouldn't be too much of a prob.
If you prefer to use an AWT/Swing setup (for example an application) rather than a JSP setup, Webstart is good for delivering online applications which operate standalone or remotely.
When you consider that the Java-Plugin and the Webstart puligin are about the same size it's just a matter of weighing up who your target clients are and whats easiest.

Re: [iPlanet-JATO] Re: using begin childName Display method

Steve,
It sounds like you have your display fields in a container view, and
that container view is inside of a view bean. I haven't tested whether
the fireChildDisplayEvents has a "deep" effect on its container view
children. Meaning that you may have to set fireChildDisplayEvents="true"
for the <jato:containerView> tag instead. If all else fails and you need
to just get it working, you can set the fireDisplayEvents="true" for
each display field tag separately.

with JavaScript. The begin<childName>Display and
end<childName>Display methods allow me to do this, in theory, but I
can not get them to execute.

Subject: [iPlanet-JATO] using begin<childName>Display method
Content-Transfer-Encoding: 7bit
I want to be able to conditionally show/hide data as well as
format
it for display without touching the model. I found the
begin<childName>Display and end<childName>Display methods that
provide the hooks to do this, but I have been unsuccessful in
getting
these method to execute. I added the
fireChildDisplayEvents="true"
attribute to the jato:useViewBean tag, but this has not helped.
I
also added some debug to the ContainerViewBase class in the
public
boolean beginChildDisplay(ChildDisplayEvent event) method to see
what
was happening. The displayMethodMap was returning null for the
child
display methods that were in the view bean. I covered all the
bases
(compiling, redeploying, etc.) and nothing has worked. Is there
anything I am missing or is there some working example of this?

The hidden field was present in the page, but it looked like this:
<input type="hidden" name="jato.defaultCommand" value=""../search"">
Seems like there is a small bug in the code generating this tag.
FYI - I am using JATO1.2
What file displays this text? Maybe I can go in and fix it and rejar
it.

To answer your question - it should work as you described. Some of the JatoSample make use of the defaultCommandChild. Can you try
running the sample BasicSample->Field Types and let us know what you
see.

Re: [iPlanet-JATO] using begin childName Display method

Oops. Sorry about that, Craig. I didn't realize I might leave that impression.
I'm sure the tiled
views work since you have so many examples of these and it's a relatively
simple concept, isn't it?
Not to mention a necessary one. I didn't have time to debug my code and find
out what I was doing
wrong where the tiled views are concerned. I decide to just try to implement
tiled views later and
just stick with one of everything for now and get that working.
Yes, I have reviewed your comments and am taking them into consideration. I am
able to save and
retrieve values with my model at this point.
Thanks.

Belinda,
He may also be binding the models, howerver, he needs to change the way
the value appears before it is displayed which is why you would use the
display events.
Your null value issue is a completely different issue and has nothing to
do with it being a tiled view. I don't want anyone getting the idea
that the tiledView binding is broken. It does work. You issue should
have something to do with the inconsistent way in which you are getting
your model. At least from what I could tell in your source code that you
sent me.
Have you reviewed my comments I sent to you in your source code?

Display request contents in JSP page

i need to display the contents in a request in my JSP.
meaning:
i have a hashmap (containing string and a list) coming from the EJB tier to struts action in an event response object, I'm sure that the request has these values. cuz i tested it in struts action using the following code:
HashMap result = (HashMap)((EventResponseSupport)request.getAttribute(WebKeys.EVENT_RESPONSE)).getPayload();
System.out.println("Sponsor name = " + result.get("sponsor"));I am able to print it in the console but i need to know how to display it in the jsp. i tried many things but i can't get it right.
first i need to display the string and then i need to iterate through the list to display its contents in a table.
any help would be appreciated.

Kindly use JSP Scriplet to load the HashMap into the Page Context.
Then you can use the Struts iterate tags to paint the contents of the HashMap

Display Chinese characters on JSP under WebLogic 6.1

We've recently migrated from WebLogic 5.1 to 6.1 and we found that all those
Chinese JSP pages cannot display properly under Solaris, but it works on
some Windows 2000 machines (but everything work under 5.1).
However we haven't made any special changes to any configuration in all
these machines. Why some of them work and some of them doesn't ? Those W2K
machines work are running English version of Windows 2000, but with Chinese
character sets installed.
Our Chinese JSP pages use big5 character encoding instead of unicode.
I've read a number of messages in this newsgroup but I'm still very
confusing on how to fix the problem ...

Hi,
I have the same problem here. I am using weblogic 6.1 on W2k server. I save
prpblem from those static contents in the jsp file, but those data in chinese
from oracle database is working fine. I create a simple jsp file just with a simple
text "hello world" in chinese, I save one as a html and one as a jsp. When I run
this two under weblogic 6.1, the html file display correctly but the jsp is not.
I try "UTF-8", "GB2312" and other charsets but all not working with jsp files.
Please help.... Thank you.

Dear Ricky,
Could you please check the following :
If you are on Sun Solaris systems please check the LC values of your
=
environment as shown in example below.
This is the cause of many troubles due to the fact that the JVM =
considers these parameters to encode.
(example given for Italian display, so I guess for you this will be =
Big5)
On Solaris 7 the right settings are=20
LC_COLLATE=3Dit.ISO8859-15

LC_NUMERIC=3Dit_IT.ISO8859-1

Also another point to check is=20
In All Weblogic Releases :
You can add the flag -Dfile.encoding=3DUTF8 in the startup line to force
=
default encoding in the JVM
In your Webloigc 5.1 property file
# WEBLOGIC CHARACTERS PROPERTIES

As you may have noted, the ressouce-path is starting from root, and =

How to display Arabic content in JSP ?

Hi all,
I used the following encoding method to display arabic content in JSP page.
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<meta content="text/html; charset=UTF-8" http-equiv="content-type"/>
I also set -Dfile encoding=ISO-8859-6 in the JVM Options.As a result the arabic data is getting displayed .
Variable "data" contains the actual arabic data.
function updateArabicData(data){
try{
document.getElementById('divtag').innerHTML=""+data;
}catch(err){
<html>
<body>
<div id="divtag" lang="ar-sa"></div>
</body>
</html>
But the problem is the arabic data getting displayed in JSP (within the <div>)seems to be jumbled up.The users say that the arabic words within a single sentence are not arranged correctly.They are mixed up.Please help me with a solution.

Data is retrieved as follows
if(msg.getField("GEN_UNICODE_MESSAGE_1")!=null){
resultString=resultString+"N"+""+new String((byte[])msg.getField("GEN_UNICODE_MESSAGE_1").value.get(0),"ISO-8859-6");
with content Type set as response.setContentType("text/html;charset=ISO-8859-6");
ISO-8859-6 -since the data contains arabic news.

It might be that the question is not interesting enough to attract people.
Or it might be that the details you provided do no suffice and some important pieces of information are missing. For eample: what are the contents of the variable? If you save the generated page, what do you get?

Having a problem in displaying Japanese characters in JSP

Hi, Could someone pls help me out with this...
I'm trying to implement my application(in Java) in English, French and Japanese languages. For this purpose, I have used ResourceBundle class. I have no problem in implementing English and French versions as they are all in Unicode.
For Japanese version, I have used a tool called NJStar Editor to create a properties file in Japanese and am saving the file with format:"Shift-JIS Text File".
Then I run native2Ascii <fileCreated><asciiConvertedFile>.
I see that the asciiConvertedFile has converted text such as "wfm_wla_filter=\u30d5\u30a3\u30eb\u30bf\u30fc".
I'm calling this variable from a JSP using <%=bundle.getString("wfm_wla_filter")%>. In the JSP i include <%@ page contentType="text/html; charset=Shift_JIS" %> to take care of the Japanese content.
The final result that is displayed in the browser is not Japanese. It is either some garbage that is not understandable or it is just "??????".
Could you pls tell me where I might have gone wrong in the any of the procedures that I have mentioned above.
Thanks in advance

Hi,
I think you need to look at this as a two-step problem.
First, you need to get the external characters from a file into the JVM. The java.util.Properties object doesn't know how to handle Shift-JIS, UTF-8, etc. According to the JavaDoc, Properties.load only understands ISO 8859-1. So, the native2ascii tool converts your Shift_JIS files into something that Properties can load. During the Properties.load process, the bytes from the properties file get converted into 2-byte Unicode characters, the only format the JVM deals with.
Second, you need send Shift-JIS bytes back to your browser. So, you need to convert Java Strings into a Shift-JIS encoded byte stream. Here's an example of how to send Shift-JIS bytes to the browser using basic Java objects:
<%@ page contentType="text/html; charset=Shift-JIS" %>
<%
ResourceBundle rb =
ResourceBundle.getBundle("MyResources", Locale.JAPAN);
String someMessage = rb.getString("someMessageKey");
writer.print(someMessage);
%>
Note that since you declared the charset as Shift-JIS, the JSP writer should send the bytes in someMessage in the response stream as Shift_JIS encoded. Under the covers, the JSP container should interpret your contentType declaration and embed a new OutputStreamWriter(out, "Shift-JIS") into the JSP Writer. In the old days with Servlets, we had to work with OutputStreams directly using OutputStreamWriter. (Note: might be SJIS vs. Shift-JIS depending on your JDK).
Lastly, I strongly recommend that you use the JSTL i18n (prefix fmt) tags for developing i18n/l10n support into your Web application vs. re-inventing the wheel.

Is there any other way to play the shuffle in a car if it doesn't have an aux facility???
There is not.
Or I wondered if you could play it through a smart tv...or do you need an apple tv box???
Not with the Apple TV, but if the Smart TV has an AUX port, you can connect it that way.

Using awt/Swing methods without having to install X on linux server

Hi,
I've written a servlet that generates PNG images and send them to your browser. However, I get the following exception:
Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.
So I set the variable... but it still doesn't work, because I have no X server on my server, and I wasn't planning on installing a huge system hogging X server...
Any ideas?
Regards
Paul Hamer

AFAIK Headless AWT (AWT that doesn't need X) is one of the enhancements of Java 1.4. You need to set java.awt.headless=true on the command line of though (-Djava.awt.headless=true).
If you're not using 1.4 you'll need som awt replacement, one of the first I found with google was http://www.logicstyle.com/projects/wct/docs/userguide.html.
Another alternatve could be to run a fake display. On one of my linux boxes I kickstart /usr/bin/X11/Xvfb :1 -screen 0 1x1x24 -fn fixed -fc fixed -fp "/usr/lib/X11/fonts/misc:/usr/lib/X11/fonts/100dpi" &in my tomcat startup script. It creates a rather light weight virtual framebuffer with one pixel and satisfy my need to use awt to generate images.

How do i use an external display with my macbook pro?

How do I use an external display with a macbook pro?

Just buy the proper adapter cord, such as MiniDisplay port to HDMI for example. Plug it in and it will be automatically recognized. Use System Preferences > Displays to set options.
The display can Mirror your primary desktop or Extend the Desktop.

Try connecting the Minidvi to the VGA and connect it all together, first try turning ing on the MBP, then connecting dvi to the the projector. Make sure your projector input is set for VGA. If noo joy invert the affored mentioned proceedure. You should see your image if not, try going to system preferences>displays, click display.
