You cannot pair your iPod to a cell phone, so forget about it.
The only way you can get free WiFi is to hang out at a Denny's, a Starbucks, or a truck stop, and I don't think your parents would approve....

Help please! Java application and web application...

Hi,
I have a problem with inserting a java application (Main.java) in a web application(index.jsp).
I found a source demo of a drag and drop application on the Internet, but now I want to
have the drag and drop application work in a Jpanel/JFrame in a webapplication.
The drag and drop application code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
public class Main {
    public static void main(final String[] args) {
        final ButtonGroup grp = new ButtonGroup();

        palette.setBorder(BorderFactory.createTitledBorder("Palette"));
        final MainPanel mainPanel = new MainPanel();
        mainPanel.setPalette(palette);
        for(int j=0; j<4; j++){
            final JToggleButton btn = new JToggleButton("Panel "+(j+1));
            palette.add(btn);
            grp.add(btn);
            btn.addActionListener(new ActionListener() {

}This application works with JFrame, but I want to display the JFrame in a webapplication (JSP Page).
I'm using Netbeans 6.0 (GlassFish) to create webapplication using Visual Web JavaServer Faces.
So in summary:
How can i display the drag and drop application into a JFrame (better in a JPanel) in a webapplication (index.jsp)??
Hope you can help...
Thanks in advance...
Greetings,
Rajsh

So have an applet that opens a JFrame... JSP or not has nothing to do with it, since it's nothing but HTML the client gets.
You can't have a JFrame embedded in an HTML page. And if you could have an applet but don't know how to get that copied code to fit inside (I mean, content pane is content pane), you might want to consider learning how to do that.

Has somebody who can help me please with JavaMail and JSP ?

I am new in JSP
And I would wish to create a JSP to send an email with attachment.
For the compilation of my JavaBeans I use JBuilder 9 Personnel version
Then I have j2sdk1.4.0
In C:\j2sdk1.4.0\
For the installation of the API javamail
it is necessary to download two jar files Mail.jar and activation .jar
http://java.sun.com/products/javamail/javadocs/index.html
it is done!
then, I copied my two files mail.jar and activation.jar in the directory
C:\j2sdk1.4.0\lib
And in
C:\jBuilder 9 \jdk1.4\lib
I have family Windows XP
Then from DOS in the the directory c:\ Documents and Settings\MEBARKIA
I have to add this line:
SET CLASSPATH=c:\j2sdk1.4.0\lib\mail.jar;c:\j2sdk1.4.0\lib\activation.jar;
Finally,
for a test, I downloaded an example of Javabean from : http://java.sun.com/developer/qow/archive/74/
the source code is:

How to keep the servlet java code the JSP engine generated?

Hello there!
          I am using some JSP in a web application, and would like to take a llok
          at the servlet java files th weblogic JSP engine generated.
          In my weblogic.properties file I have the following line:
          "# Set up WebLogic JSP properties
          weblogic.httpd.register.*.jsp=weblogic.servlet.JSPServlet
          weblogic.httpd.initArgs.*.jsp=\
          pageCheckSeconds=1,\
          compileCommand=F:/VisualCafeEE/bin/sj.exe,\
          workingDir=F:/weblogic/myserver/classfiles,\
          verbose=true,\
          keepgenerated=true"
          However, the only things I can find are the class files compiled from
          the servlet java files.
          Any suggestions?
          Thanks.
          Jeff.


Moerover, if you follow the example web.xml Weblogic provides
          (http://www.weblogic.com/docs51/classdocs/sample_web_xml.html), the parser
          would complaint big time.
          The <servlet> and <context-param> tags have to be switched.

Servlet to Bean to JSP

I have a JSP that sends two form values to a servlet. I want to send those parameters to a bean for calculation and then send the results back to the JSP. I am stuck on the Servlet code and don't know how to send it back with the bean don't know how to start the bean:
import javax.servlet.*;
int rate, hours;
public class calculateParamServlet extends HttpServlet{
     public void doPost(HttpServletRequest req, HttpServletResponse res) throws
     ServletException, IOException {
          rate = req.getParameter("hourlyRate");
          hours = req.getParameter("hours");
}Any help would be appreciated,
Kent

A bean is just a Java class so the same rules apply.
e.g in the doPost method,
myBean mybean = new MyBean();
mybean.setRate(rate);
mybean.setHours(hours);
out.println(mybean.getCalc());
If you want to save the reference to the bean, save it in the application or session scope and check for its existence before creating it again. You could also do all this directly from the JSP.

It's required that you authentificate yourself at the smpt server
The following snipplet sends a msg using the smtp protocol.
Transport tr = session.getTransport("smtp");
tr.connect(smtphost, username, password);
msg.saveChanges();     // don't forget this
tr.sendMessage(msg, msg.getAllRecipients());
tr.close();If this still fails You can also try to set the property mail.smtp.auth to true.
mail.smtp.auth      boolean      If true, attempt to authenticate the user using the AUTH command. Defaults to false.see also http://java.sun.com/products/javamail/1.3/docs/javadocs/com/sun/mail/smtp/package-summary.html
for a complete description of the properties supported by the smpt transport.
hope it helps

The relation of Servlet , bean and jsp

servlet can output to IE directly? I mean that design a servlet adding some code in the service method, compile it, input URL: localhost:8080/test/servletname, can I get result? (Tomcat, register servlet in web.xml)

yes that's the point!
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class HelloWorld extends HttpServlet {
     public void doGet( HttpServletRequest req, HttpServletResponse resp )
     throws ServletException, IOException {
          resp.getWriter().println( "<html><body>Hello World</body></html>" );
}

Help converting between Java Dates and SQL Dates

Hey all,
I'm working on a JSP to allow a user to enter information about news articles into a mySQL database. I'm using text fields for most of the data, and most of it is transferred correctly when the user hits "Submit." However, I am having a problem with the date field of the mySQL database. Basically I'm trying to retrieve the current date from the JSP page, and then insert this into the date field of the appropriate table when the user hits submit. The problem is that I can't typecast a java.util.Date or even a java.util.Calendar to a java.sql.Date object. I've tried lots of approaches, including creating a new instance of java.util.Calendar, getting all its fields and concatenating them onto the date variable, but this doesn't work.
Anyone know how I could easily convert between java.util.Date or java.util.Calendar and java.sql.Date?
Thanks!

Thanks for the help!
I can correctly display the current date on the page in java.sql.Date format now, but it's still not being inserted into the database correctly. The specific code is as follows:
java.util.Date dt = new java.util.Date();
java.sql.Date sqlDate = new java.sql.Date(dt.getTime());
(As you wrote)
Then (after connecting to the database etc.):
PreparedStatement pstmt = con.prepareStatement("INSERT INTO NEWS(NEWSDATE,DAYOFWEEK,AUTHOR,HEADLINE,CLIP,PUBLICATION,LINK,NEWSLOCATION,DATECREATED,DATEMODIFIED,CATEGORY,KEYWORDS,PHOTOURL,PHOTOGRAPHER,AUDIOURL) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");
pstmt.clearParameters();
pstmt.setString(1,date);
pstmt.setString(2,dayofweek);
pstmt.setString(3,author);
pstmt.setString(4,headline);
pstmt.setString(5,clip);
pstmt.setString(6,publication);
pstmt.setString(7,link);
pstmt.setString(8,newslocation);
pstmt.setDate(9,sqlDate);
pstmt.setString(10,datemodified);
pstmt.setString(11,category);
pstmt.setString(12,keywords);
pstmt.setString(13,photoURL);
pstmt.setString(14,photographer);
pstmt.setString(15,audioURL);
int i = pstmt.executeUpdate();
pstmt.close();
All the other fields are retrieved with request.getParameter from text fields. Any idea why the DATECREATED field is being updated to all 0's but the others work fine?
Thanks again.

Need help with a java loop and word program

do you know any way to get a Scanner object to select a random string in a text file?
ok pretty much I have a text file that isa list of 5 letter words. I need to select one at random.
the only way I could think was to scan the file, get the entire nu of words, have Math.random choose a random nu then loop scanner.next() and have the loop condition run the Math.random amount of times
but... when I do that I CANT ACCESS THE WORD OUTSIDE THE STUPID LOOP grrr...
i'm annoyed lol
this is the loop code that selects the random word
int random = (int) Math.random() * numberOfWordsInFile + 1;
int chooseLoopCount = 0;
while (random >= chooseLoopCount)
String theWord = scan.next();
theWord = theWord.toLowerCase();
chooseLoopCount += 1;
see it's assigned properly to be the output of the scanner in all lower case letters, but outside the loop, the variable doesn't even exist
anyway any suggestions would be awesome. thx

String theWord = null;
while (...)
// set theWord in the loop
// access to theWord is now available here, as it is in scope.
// bear in mind if your loop didn't get executed, theWord is still null

Help with java beans on initialisation

hi
I'm trying to use java beans for the first time
I'm calling a bean from a JSP page; the bean will not exist when the page is first called
<jsp:useBean id="user" scope="session" class="business.User" />I want to use properties/private attributes of the user bean to make a form "sticky" on the page, so that once the user has entered something, their input is there the next time they visit the page (eg back or via an href)
The problem is that the bean creates a user on the first call with properties that are null, which means that "null" is displayed on my form when it first appears
<td><input type="text" name="firstName" value="<jsp:getProperty name ='user' property='firstName' />"></td>I can code this out using a scriptlet but this defeats the beauty of java beans and jsp tags. How do I translate a null property so that nothing is displayed on the form?
Thanks for your help

So.. my mini-designer should be something like an editor,with a pallette with beans(like JavaBeans) and when a user is dragging a bean into a form,my applicaton should generate the code fr that bean....something like that :)

MVC Design Help, Single Servlet, How do I access the Model and DB

Hi all. New here and looking for some help.
I am currently writing a website that allows the creation of users, that may upload articles and post comments on articles. Im trying to develop using MVC. I have a single controller servlet that processes POST actions throughout the site (eg. InsertArticle, DeleteArticle, ModifyArticle, etc..)
Now my problem is, just how do I retrieve the articles from the database? .. for example, if I load up a page http://localhost/articles.jsp which should display all the articles currently in the site.. I would have a function say getAllArticles() which should return a collection of all the articles. I can then iterate through the articles in the jsp page.
I am trying to use <jsp:useBean...etc.> BUT.. my articles bean constructor takes a databaseconnection object as a parameter. If I use useBean I cant pass the databaseconnection object to the bean and I get an error because it cannot create the bean.
Any help on this would be appreciated as well as any tutorial links. I also looked at the petstore blueprint program on the sun website, but that program has me completely lost with all the xml. I would prefer not to use custom tags or struts for now. I would like to keep it simple with snippets of java code in the jsp pages for data retrieval and display while keeping all the business logic in the beans of the model. I would also like to keep this relatively secure. I am developing using Oracle Jdeveloper 10g.
Thanks
Jazz

Hey steve, thanks for that.. but thats exactly what i
dont want to do. I also realize that ive been writing
the ejb's incorrectly to begin with and have begun to
rewrite them. However maybe I can make it easier..
what im trying to do is precisely what is in this
diagram..
http://gsraj.tripod.com/jsp/jsp.html
the problem im having is where it passes data back to
the jsp page.. entity beans cant (or shouldnt?) be
accessed directly from jsp pages.. which means i
create a session bean which interacts with the entity
bean and can return information to the jsp page.. i
understand what i have to do.. i just dont know how to
do it.. been searching for google for tutorials and
etc.. this site is the closest ive come but .. as you
can see it says "more to come" ..
thanks again guys really appreciate itAhhh. EJBs. Enterprise Java Beans and JavaBeans are two completely different beasts. I know nothing about EJBs, except:
1) They are much harder to use (and serve a different purpose I assume) then JavaBeans
2) Tomcat (the server I use) doesn't support them.
Sorry I can't be of more help.
