"I am unable to Download the application in the Java Web Start"
If webstart in not actually downloading the jar - is the jar in the correct location?
Is the server named dev01 and the directory structure actually /Dummy/New?
Note: you do need to set up the mine type JNLP on your server,
In my case the location of the JNLP file and main jar file passport is in the following directory.
c:\Inetpub\WIMRoot\application
The additional jars are in
c:\Inetpub\WIMRoot\application
I hope this may give you some clue

How to get the current path of my application in java ?

how to get the current path of my application in java ?
thanks

To get the path where your application has been installed you have to do the following:
have a class called "what_ever" in the folder.
then you do a litte:
String path=
what_ever.class.getRessource("what_ever.class").toString()
That get you a string like:
file:/C:/Program Files/Cool_program/what_ever.class
Then you process the result a little to remove anything you don't want:
path=path.substring(path.indexOf('/')+1),path.lastIndexOf('/'))
//Might be a little error here but you should find out //quickly if it's the case
And here you go, you have a nice
C:/Program Files/Cool_program
which is the path to your application.
Hooray

Creating a Gnutella downloading application in Java

Hi I am trying to create an application in Java that is able to simplly download a file from a remote host using the Gnutella (peer-2-peer) protocol. The application accepts 3 arguments:
1 host (IP address or hostname)
2 port (the remote gnutella application is listening on)
3 ss1hash (unique code for the desired file)
Gnutella file transfers work by sending HTTP get request headers to the remote host, which includes the information from the arguments.
This is the application i have created so far...:
import java.io.*;
import java.net.*;
public class GnuttDownloader{
        public static void main(String[] args) throws IOException{
                String host;
                int port;
                host = args[0];
                port = Integer.parseInt(args[1]);
                String sha1Hash;
                sha1Hash = args[2];
                Socket socket=null;
                System.out.println("Starting Downloader...");
                try {
                      socket = new Socket(host, port);
                  // Send request to get root
                  // Be sure to end string with two sets of carriage
                  // return - newline characters.
                  OutputStream outputStream =
                      socket.getOutputStream();
                  PrintWriter out = new PrintWriter(outputStream);
                 out.print ("GET /uri-res/N2R?" + sha1Hash + " HTTP/1.1\r\n"
                            + "User-Agent: Limewire/3.3.5\r\n"
                            + "Host: " + host + ":" + port + "\r\n"
                            + "Connection: Keep-Alive\r\n"
                            + "Range: bytes=0-\r\n\r\n");
                  out.flush();
                  // Fetch response
           InputStream inputStream =
             socket.getInputStream();
           InputStreamReader inputStreamReader =
             new InputStreamReader(inputStream);
           BufferedReader in =
             new BufferedReader(inputStreamReader);
           String response;
           while ((response = in.readLine()) != null) {
             System.out.println(response);
           System.out.print("ARGUMENTS:\nHost: " + host + "\n"
   + "port: " +port + "\nFile's sha1 code: " + sha1Hash);
           // Close everything
           out.close();
           in.close();
           socket.close();
         } catch (IOException e) {
           System.err.println("Problems talking to " + host + " on port:" + port);
           e.printStackTrace();
     }I have not implemented the file reading/saving part yet, but the application should at least give me a response such as:
HTTP/1.1 200 OK
Server: Gnutella
Content-type: application/binary
Content-length: 4356789
this should verify that it accepts my request, and i should expect a file to be delivered about 4MB long. However this does not happen.
The application manages to connect to a remote host i.e. if I specify a host on my LAN (192.168.0.3) running LimeWire 3.3.5, but instead of receiving the above response, I receive the follwing:
HTTP/1.1 400 Malformed Request
Server: LimeWire/3.3.5
Content-Type: text/plain
Content-Length: 17
Connection: close
Malformed Request
Therefore, i know it is connecting and sending the header, but it seems that it is not understanding the actual header that I send. I can't see anything wrong with it, is there anything that I am doing wrong? Has anyone done anyting like this?Can anyone help me here?
Thanks in advance.

If anyone can help here please????????????????????????????????

Add jar file to forms application standard java library

Overall Problem
I created a jar file using JDeveloper to be loaded as a bean in forms builder. But the jar file ended up being really large because I had to add some standard libraries that JDeveloper knew about but Forms didn't to this jar file, it takes forever to load in my forms application.
Background
Jdeveloper has a drop down list of standard libraries that aren't commonly used that a developer can have included/referenced into their java project.
Oracle Forms Library
One of the standard libraries in JDeveloper that can be referenced when compiling a project is the Oracle Forms library. I have to reference this library in my compilation of my java project in JDeveloper because some of the java code in this project requires the Oracle Forms library. When the jar file is created in JDeveloper the Oracle Forms Library isn't actuaally physically located anywhere in the jar file that is produced for deployment. But the jar file runs perfectly in my forms application. Forms builder and the forms application server seems to already know about the Oracle Forms library.
Java Media Framework Library
There is another standard library listed in JDevelopers drop down list that I recently chose to use in my Java Application, the Java Media Framework library. But my forms application couldn't find any of the Java Media Framework classes when it launched the jar file that was deployed from JDeveloper. Obviously the classes wern't physically located in the jar file I created, because I figured that the forms application server/forms builder would already know about about this standard library that JDeveloper knew about.
Not very effective Solution
So I physically put/included the whole Java Media Framework Library into my jar file and then my form launched fine. But it now takes forever to load. How can I add the Java Media Frame work library jar files as one of the standard libraries that the forms builder and application server already sees (Like the Oracle Forms Library) without having to put the library in the forms/java folder and wait for the this jar file to download to the user's cache?
Side note: The Java Media Framework Library is allowing the ability to launch video from my form. Very useful tool!!! So it would be good if forms had this already added as a standard library like it is in JDeveloper. But I only see the ability to reference this library in DS 10gR2 for JDeveloper.
Thanks,
Michelle

Yes I have successfully been able to run a javabean application that uses the Java Media Framework methods within a forms module. The video seems to play and interact normally in the forms environment (launched from a DS or the AS).
Basic Requirements
Develop the java application functionality look and feel, including adding funtionality calls to the JMF library where needed.
Develop an Oracle Forms Interface wrapper that will be the initial class called from the bean area, to hande any communication between the bean and the form.
Configure the deployment of the jar to physically include all the needed classes from the JMF library.
Sign the jar file and make sure it is placed in the forms/java folder and referenced in the appropriate forms configuration files.
Depending on the type of video that the will be played certain .dll files might need to be added to the users system folder. Using H264 (.mov) should work fine without any extra .dlls.
Thanks,
Michelle

A question about design of Java Application on java card.

Hi every one,
I have a question about design of Java applet on java card,
There is an application on my card that it is not java card, it include a DF and some EF under DF, I would like to know if I want to have this application on java card ,how can I design DF and EF on java card ,I mean is there any relation between DF,EF with applet and file? for example can I say DF is same as applet and EF is same as file?
I'll appreciate for any help .
yours sincerely,
orchid

hi
you can write a java class for DF.
an instance of DF class have some EF objects.
for example,
samples/com/sun/javacard/samples/JavaPurse/CyclicFile.java
implements ISO 7816 CyclicFile ( EF )

Close a running application from java........

Hi all
I have opened an application say MSWORD from my java class using Runtime.getRuntime(), Now on close button i need to close the application and on the save button of the application i even want to save the application from java command
The question is HOW????
please reply,
Thanx,
Amitt

can I open the konsole from java??Yes.
First you must figure out how to do that from the command line yourself. That has nothing to do with java.
Note that that how you do that MUST account for the fact that the "command line" is actually a shell. Some commands must be run by running the shell as the actual command and then passing the desired command as an option to the shell (the actual command.)
Again you can google for examples.

Let's say your Weblogic domain for Contract Management is located in
C:\Oracle\Middleware\user_projects\domains\cm, please first check if the com folder exists in the domain folder. If the folder not exists, you have to reinstall Contract Management using an administrative account.

Hi, All,
I got the following error when I try to install Web Application Server Java 6.40 SP9 on my laptop using the CD that comes with the Book 'Java Programming with the SAP Web Application Server'. I'm currently using window XP.
The installation failed on the 3rd step 'SAP System Installation'.
I logged on my laptop as my own userid, but I should have the administrator's rights.

Do you have any ideas what it means? Any inputs would be greatly appreciated.

How can I know the version of Application Server Java Virtual Machine

How can I know the version of Application Server Java Virtual Machine?
Thanks a lot.

Thats easy. Your jdk/jre are located in the App Server home directory. Just run the java command under the jdk directory with the "-version" switch and it will provide you with detailed information about your VM.
For example if you're doing it at command prompt it will be something like
java -versionI hope this will be useful to you.

Hi,
The answer depends pretty much on how ambitious you are, and several articels and books can be written on the topic, so it's unfortunately not something that can be fully answered in a short post.
My best advice is that you google on MVC and on how to create layered applications. You can after that start reading e.g. JDBC tutorials and Swing tutorials (if that is the UI that you are going to use).

Ps. I would probably not use MySQL as database for an address book. I would instead use a database that doesn't require installation. E.g. H2 or Derby.

How to create a trial version application in java

hai,
i'm developing an application in java. i have to made this application as a 30 days trial version... if the customer copy the application and paste it in another system it should not work.. how to perform this task.. i'm new to this task.
any one help me

if the customer copy the application and paste it in another system it should not work..That is an extremely hard requirement. You would need to write self modifying code to stop the installer from functioning after its first successful run. Other than that, Java has good cryptography support, and you can make your app writes out the birthday of the time bomb alone with a signature to avoid tempering.
