Java/jsp programing using timer

what I want to do is say
at 8am every day
send email news letter to all members on the database.
without the press of a button on my side.
anyone done such programing with java?
Sample codes will bve much appreciated.
Thanks in advance

This sounds a good idea nut that means the hosting co
have to allow the OS job to trigger it az 8 pm on
their system because something has to be on
permanently for it to happen.Well, that is information you might have given right away. In that case, you might be short of luck for a reliable way to do it. At least I can't think of a way - if all you can do is call a servlet, you'll need to activate it on 8 am yourself daily. I don't think you can make the servlet run in an endless loop that keeps it "alive" for eternity, to repeatedly trigger the mailing. I mean you probably can, but my bet is that it gets killed by the container after a certain timeout.

How to execute a .exe file in java(Jsp) without using a process ???

Hi All ,
How to execute a .exe file in Jsp without using a process ??? ...
Is it Possiable ????

But as this a web application ... By using Runtime i'm getting some probs ..
Let me guess, you want your web application to run a program on the client and to your surprise that's not working?
Ain't gonna happen.
its taking more time to execute .... that's y is there any other option to execute .exe file other than Runtime.getRuntime().exec("filename");Write proper English and you may be taken more seriously.
1) it's not "taking more time to execute", whatever that's supposed to mean.
2) there's no other way to execute something. Not that you should every use even that way anyway
3) whenever you start thinking of executing external programs from Java, start thinking of not using Java in the first place.

Help needed in executing the java/jsp program from UCM .

Hi ,
I have a .jsp program running in my Jdeveloper which when executed pops a window to browse and select files and with few custom options .
But i want to execute that Program from within UCM (create a new jsp page in UCM OR provide link ? i am not sure .... ) , could anyone help on how i can execute/run the program from UCM ?
thanks in Advance

If your jsp makes use of jars you may want to look into using a WAR instead. You can check the WAR into content server and there is even a link on the administration page for JSP Web App Admin. Treating the JSP(s) and jar(s) as an entity may be a more successful path for you.
You can find some jsp examples and ever a war example in this directory: <install root>\samples\JspServer

New in Java: java applet program using multithreading

I am trying to write a program, which should move the words "Java Platform2" from left to right every time we 'refresh'.
Can you please advise what is wrong in the logic??
import java.applet.*;
import java.awt.*;
import java.lang.*;
public class Ch61appth extends Applet implements Runnable
int i=30;
int x=10;
int y=30;
Thread t,cur;
     public void start()
          t=new Thread(this);
          t.start();
     public void paint(Graphics g)
          g.setColor(Color.blue);
          g.drawString("Java Platform2",x+i,y);
     public void run()
               if ((x+i)<400)
                    {     i=i+20;
                    else
                    {     i=20;
          //cur=new Thread.currentThread();
          repaint();

thanks for reply
i tried using for loop. Earlier also i had tried using while loop with condition t==Thread.currentThread()
The problem i am facing is the string just does not move and even after clicking refresh, it appears at same locations.
CAN U ADVISE>

I am trying to create variables so i can make a calculator (right now i only have buttons 1, 1 and multiply). //This is when the error says "Local variable first is accesed from

Please post code within code tags (press the "code" button).
Why are you using an inner class? Simplify:
public class OSC implements ActionListener {
button1.addActionListener( this );
public void actionPerformed( ActionEvent e ) {
    if ( e.getSource() == button1 ) . . .

Java Network Programming using UDP protocol

I am trying to send the object using UDP protocol.
In my client class it is giving me NullPointer excetion at clientSocket.send(sendPacket); although sendPacket is not null it has the value that I am passing.
Here is the code :
private boolean clientSrvrComm(AuditorData audData) throws Exception
          boolean result = false;
          ByteArrayOutputStream barray_out = new ByteArrayOutputStream();
          ObjectOutputStream obj_out = new ObjectOutputStream(barray_out);
          obj_out.flush();
          obj_out.writeObject(audData);
          obj_out.flush();
          // sending the data to the server
          byte[] sendData = barray_out.toByteArray();
          DatagramPacket sendPacket = new DatagramPacket(sendData,sendData.length,IPAddress,serverPort);
          clientSocket.send(sendPacket); // getting exception at this line
          return result;
     } // method end
I am passing audData through main method.
Any help would be appreciate.
Thanks,
Swati

actually it shouldn't give the null pointer exception and send the object to the server.
I am not able to get, why it is throwing the exception, even there is no class for debugging.

Can anyone clarify my doubt in a simple JSP Program ?

when we write a simple jsp program such as helloworld.jsp does a
class file or servlet be created when we run the jsp program using a
web browser and Tomcat ? if so please tell the folder(path) in tomcat
where this class file will be located or stored .Thankq

JSPs will (usually) be compiled into class files representing Servlets, yes. But that's something that happens internally inside the application server and shouldn't concern you.
Why would you need to know where it resides? It seems like a code smell if you need that information.
If you're just curious, then look into the work directory of your tomcat.

I uses Time Machine to transfer files and program from old to new MacBook Pro. Aperture doesn't work. Every time I open Aperture the computer need me to key in Serial number. How do I fix it.

Hi There,
I purchased a new MacBook Pro Retina 15". Since I am using MacBook Pro and I uses Time Machine for backup files and program. Store saleman tell me I can retore my existing program and files from old MacBook Pro to new MacBook Pro computer. After files transfer it seem to be OK. But only Aperture has a problem when every time I open Aperture to edit photos, MacBook Pro ask me to key in the Aperture Serial Number that made me so inconvinent. Did any one have meet this problem and can someone teach me how to fix it, Thanks.
Nelson

Either the license files were not transferred or it has to be relicensed.
Remove and then re-install aperture. On an rMBP this should take only a couple of minutes.

Setting profile option values using Java Concurrent Program

Hi,
I have a java concurrent program in which i am trying to update a profile option which is enabled only at site level, but the values are not getting committed once the CP completes.
1. I am using CpContext.getProfileStore().SetProfile(<name>,<value>) to set the value.
2. I am printing CpContext.getProfileStore().getProfile(<name>) in the same run and this works.
3. BUt once the CP completes, the values are gone. Seems we have to issue a commit.
3. So i used CpContext.getJDBCConnection().commit; Even this doesn't commit.
Pls. suggest. Has anyone used these APIs to update profile options?
Thanks,
Suresh.

I am not not a java expert, but pl see if MOS Docs 305710.1 (A SAMPLE JAVA CONCURRENT PROGRAM) and 827563.1 (How To Create a Java Concurrent Program?) can help

Display pop ups in the jsp by using Java script

Hi
can any body say ,how to display pop ups in the jsp by using Java script ?

that's correct. You can use the below code for AJAX request.
<script type="text/javascript">
var httpObject = getHTTPObject();
//create XMLHttpRequest object
function getHTTPObject() {
     var xmlhttp;
     if (window.XMLHttpRequest) // if Mozilla, Safari etc
          xmlhttp = new XMLHttpRequest();
     else if (window.ActiveXObject){ // if IE
          try {
               xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
          catch ( e ){
               try{
                    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
               catch ( e ){}
     return xmlhttp;
//define the function to send the request
function sendRequest(){
    var currDesc = document.getElementById("description").value;
    var URL = "manageMaintAction.do"; //action mapping in your struts-config
    var queryString = "currDesc="+escape(currDesc); //get the currDesc value in your action class like request.getParameter("currDesc")
    httpObject.open( "Post", URL, true );
    httpObject.onreadystatechange = cbFn;
    httpObject.setRequestHeader( "Content-Type", "application/x-www-form-urlencoded");
    httpObject.send(queryString);
//callback fn
function cbFn() {
    if (httpObject.readyState == 4)
         if (httpObject.status == 200)
          var result = httpObject.responseText;
          alert(result);
</script>
