Failed to lad main class manifest attribute from

what exatly it meansIt means that your Manifest.MF for the JAR file should contain an attribute called Main-Class pointing to a class containing the main() method.
Something like this should be present in META-INF/Manifest.MF :
Main-Class: MyApplicationMain

How to make web applications in JAVA

Hi!
Iam an experienced Web Programmer in languages like PHP,CGI,ASP but i haven't drunk my first cup of JAVA yet. My idea is to start making web applications in JAVA as soon as possible. But the first challenge i am facing is of choosing from things like J2SE,J2EE,J2ME. I just bought a book 'JAVA : The complete reference(J2SE 5.0)' by Herbert Schildt. It has a only a small percentage of text that looks like 'Web Programming' in the chapter 'java Servlets'. So now I think its J2EE that has all the web programming stuff. So basically iam confused and can't figure out what to read! So can anybody please tell me that what learning curve do i have to take to start java web programming? Remember, i hardly have any Java specific knowledge. But iam adept at OOPS programming(thanks to PHP).Do i have to learn that whole J2SE book if j2EE is what i need?And i don't really bother about syntax of JAVA language coz i have worked on C as well. Infact, PHP is much like C as well.
Thanks for any Help

I will once again clarify what i am sayin to avoid any confusion...
PHP is an object oriented server side scripting language.
PHP has its own semantics and OOPS defination. unlike ASP it is not dependent on other languages to execute the logic of script.
PHP has it's own PARSER. The function list of PHP is also impressive. The OOPS are pretty strong, some things are missing like Function overloading etc.
But PHP 5 has them too. (I use PHP 4.3.8). PHP runs on APACHE server or IIS with APACHE 2.0 PATCH. OOPS of PHP is very similar to JAVA(PHP also has $this-> operator). The main diffrence between PHP and JAVA or C/C++ is that variables are defined with $ sign.Actually they are never defined , they are created on fly. Array traverse functions of PHP make functions of other languages look primitive.
You can go to http://php.net and make a search on available functions and features of PHP in the online manual.
thanx.

The JSP Demo makes a string comparison, but I want to use the XML Parser. How can I do this ?
Response DTD Example:

<map_response>
     <map_image>

How to make "Levels" in simple java game

I just wanted to know if anybody knew how to make "Levels" in a java game. In my case, it is to change two polygons that are used in the background. I think you have to use an array of some kind, but i dont really know.
Here is my source, the polygons are by the massive ///////// areas.
I cut out the majority of the program, because it was too long.
public class collision extends Applet implements MouseListener,MouseMotionListener
    private Image rickImage,mazeImage;
   Image Buffer;
   Graphics gBuffer;
   int x, y;
   int[] LeftWallX = {0,204,204,149,149,162,162,243,260,235,259,232,260,230,207,207,0};
   int[] LeftWallY = {500,499,402,402,341,324,227,191,157,141,135,123,116,109,86,1,1};
   //int[] PlayAreaX = {204,204,149,149,162,162,243,260,235,259,232,260,230,207,207,263,263,245,282,262,274,257,273,250,184,184,170,170,208,216,216};
// int[] PlayAreaY = {499,402,402,341,324,227,191,157,141,135,123,116,109,86,1,1,86,103,115,129,138,147,155,201,230,323,340,384,384,402,499};
   int[] RightWallX = {500,500,263,263,245,282,262,274,257,273,250,184,184,170,170,208,216,216};
   int[] RightWallY = {500,0,1,86,103,115,129,138,147,155,201,230,323,340,384,384,402,499};
   boolean mouseInside, collide;
   boolean rolled = false;
   boolean msg = true;
   int sX=204,sY=490,sW=12,sH=9;
   //Declare the rectangles

             rickImage = getImage(getDocumentBase(), "rick.jpg");
             mazeImage = getImage(getDocumentBase(), "maze1.jpg");
             collide=false;
             Buffer=createImage(getSize().width,getSize().height);
             gBuffer=Buffer.getGraphics();
             rightWall=new Polygon(RightWallX,RightWallY,18);
             playerArea= new Polygon(PlayAreaX,PlayAreaY,31);
             leftWall= new Polygon(LeftWallX,LeftWallY,17);
        public void paint(Graphics g)
             drawStuff();
             g.drawImage (Buffer,0,0, this);
*/

I'm not exactly sure in your case what you are trying to accomplish. If all you want to do is make new polygons for your levels then you will simply need a Vector of type level (or polygon). Store multiple levels/polygons in that vector. This can be done many ways, probably the most efficient way would be to create a class Level of sorts and create each level object from there. This way you have all your levels stored into that vector.
I have made programs where the levels/mazes are randomly generated based on certain parameters (this way you would not need to define any specific level). This can be done inside the Level class and added to the vector so that when a level is randomly generated there are literally infinite possibilities. I would suggest posting all your code or at least a breakdown UML diagram of what is going on in your entire program.

How to print PDF files using java print API

Hi,
I was goign throw lot of discusion and reading lot of forums related to print pdf files using java api. but nothing seems to be working for me. Can any one tell me how to print pdf files using java api.
Thanks in advance

Mike,
Can't seem to get hold of the example described in your reply below. If you could let us have the URL to get then it would be great.
My GUI application creates a pdf document which I need to print. I want to achieve this using the standard Java class PrinterJob (no 3rd party APIs I'm afraid, commercial restraints etc ..). I had a stab at it using the following code. When executed I get the pretty printer dialog then when I click ok to print, nothing happens!
boolean showPrintDialog=true;
PrinterJob printJob = PrinterJob.getPrinterJob ();
printJob.setJobName ("Contract.pdf");
try {
if (showPrintDialog) {
if (printJob.printDialog()) {
printJob.print();
else
printJob.print ();
} catch (Exception PrintException) {
PrintException.printStackTrace();
Thank you and a happy new year.
Cheers,
Chris

Deploying no java applications using Java Web Start

Hi,
I am new to java web start. Is it possible to distribute non java applications using java web start. I have an APP which can run on a desktop in standalone mode. The app has jusy HTML and Java script files. Is it possible to package this app and deploying using java web start? I am assuming If it is possible, I can make updates to the packaged app in the web servers and the updates will be downloaded next time the app is used provided configurations are correct?
thx

The app has jusy HTML and Java script files. Is it possible
to package this app and deploying using java web start? Not really. Resources for JWS need to be zipped,
while this HTML/JS app. will (I guess) not work from
inside the depths of a Jar (or Zip) archive.
Note that you can organise for those files to be
downloaded and expanded onto a known place
on the user's disk, by using an 'installer' element,
but..
...I am assuming If it is possible, I can make updates to the
packaged app in the web servers and the updates ..installers are only called once, and do not 'update'.

How to make client application

hi....

I seached bea document.. but I can't it.
if someone have sample(.ear or .jar), I hope you it share...

Hi
Client Application can be any Java class, JSP etc which is a part of multi
tier architecture which accepts input from Client and directs request to the
middle tier for processing. You can refer to
http://e-docs.bea.com/wls/docs61/jsp/index.html
for building jsp's as Client application.

Executing Jar Application using Java Programs

Hello there,
How can I run a java application using java programs.
Desc:
public class someapp {
public static void main(String[] ext) {
// How can I execute a jar application from here through java code
}

You could use java.lang.Runtime.exec(). Another way could be loading the main class of the jar file and invoking its main method dynamically.

How to access NTFS entries using Java

I want to access and read the attributes of a file stored in the Master File Table of NTFS.
How should I do it using Java. Is using native code and using JNI the only way or is there a package in Java that supports this?
Thanks

WebSphere Application Server has a bunch environmental variables such as log locations. These are held at the "server", "node", and "cell" level.
To access them, you have to get the right context. Something like this, I believe...
InitialContext initialContext = new InitialContext();
initialContext.lookup("foo:bar/baz/blah"); //correct context hereGo to the IBM website for WAS and do a search on namespace bindings. That should give you some more information.
Good luck.
