GUI Jar file creator

Forgive me but I really do like the GUI front ends to Java programming. I find it much easier to just point and click.
I can see in Forte where you can create your documentation (JavaDoc). But I don't see where you can create a Jar file. Does it rxist in Forte somewhere? Or is there a Gui Jar program? If so where can I find it?

Thanks for the link. Looks like I have 1.0. I'll have to upgrade to 1.4
Hi. I'm glad I could help.
Sun One Studio is Forte.
I am using Community Edition Four, Update 1 which I
dowloaded as a cobundle with the sdk. The link below
will take you to the download page.
http://java.sun.com/j2se/1.4.1/download.html
The Manifest file is created within the Jar Packager
sequence.
After you've specified properties, defined the
contents of the jar, modified contents if necessary,
you arrive at the screen where the manifest is
created. The screen appears blank at first, but press
"Generate" at the bottom and basic attributes are
written to the file ie "Manifest-Version: "
"Created-by" ...
And from there you can enter a Main-Class if any and
any additional attributes you wish to enter.

Open jar files through gui

I have a program where i am trying to have a button allow the user to open a jar file from a different program and run that. Does anyone have any idea how i could go about this?

First how do you search the jar file for that?You can use JarFile, its getManifest method, and Manifest to look up the value of the Main-Class attribute. If there is no Main-Class attribute in the manifest, you probably need to load each and every class file in the jar and check via reflection if the class has a main method or not.

How to authenticate a JWS Client download of jar files on a web server

Here is a history of how i tried to implement the auth system:
The resources(jar files) cannot be downloaded by any HTTP client from the server without some authentication method.
As JWS is not reliable when using cookies (only 1.5 supports them, but with problems when in JNLP file i specify j2se version=older that 1.5) , i implemented another mecanism that works like this:
1. 1.The template JNLP looks like this
<?xml version="1.0" encoding="utf-8"?>
<jnlp codebase="http://10.3.0.62/" href="mapped/#JWS_CODE#___#PLATFORM#___app2.2.jnlp">
    <information>
       bla bla
    </information>
    <security>
        <all-permissions/>
    </security>
    <resources>
        <j2se version="1.4"/>
        <jar href="http://10.3.0.62/mapped/gui.jar?jwsid=#JWS_CODE#" version="2.2"/>
        <jar href="http://10.3.0.62/mapped/data.jar?jwsid=#JWS_CODE#" version="2.2"/>
        <jar href="http://10.3.0.62/mapped/log4j.jar?jwsid=#JWS_CODE#"/>
    </resources>
    <application-desc main-class="com.bet.blues.gui.Application">
        <argument>-host</argument>
        <argument>ursus</argument>
        <argument>-port</argument>
        <argument>17771</argument>
    </application-desc>
</jnlp>2. All resources found in /mapped/ directory are mapped to JWSServlet
3. The users login to a site , clik on link , /mapped/app2.2.jnlp , the servlet checks if the session is active , gets the PLATFORM form browser request header , gets the JWSCODE for the logged user, replaces this in the template, and returns it to the client
4.Now after the 1st download the JNLP file is opened by JWS Client , that checks for latest version , requesting the JNLP file again
like this:
GET http://10.3.0.62/mapped/f12ks21092___windows___app2.2.jnlp5.Now the servlet sees the the request has a JNLP file name with an ID and PLATFORM, and serves the JNLP as before
6.The JWS Client will request for JAR Files
GET http://10.3.0.62/mapped/gui.jar?jwscode=f12ks21092?version-id=2.2Note: that i have forced JWSID parameter in the URL, that's why the query string contains 2 "?"
- forcing this is because the mapped/*.jar is redirected JnlpDownloadServlet that supports versions , diffs - i cannot use 'version' to put there the jswid param(e.g .../mapped/gui.jar version="fk12ks21092_2.2" because the JnlpDownloadServlet will not find this version , and if JWS Servlet will redirect to JnlpDownloadServlet with correct version param in request, the JWS Client will raise an exception because version responded is not right(JNLPDownloadServlet marks in response HTTP header the version of the jar so JWS CLient will chek it)
JWS Client expects version 'fk12ks21092_ver2.2'; to correct this i should modify the JnlpDownloadServlet and i shouldnt
THE PROBLEM :
on older versions than 1.5 JWS Client raises an exception because it wants to create a temp file named
" gui.jar?jwscode=f12ks21092" because it contains "?"
Only with 1.5 that seems to parse the jar name until it meets "?" char :(
Thats why i wanted to send an error to the client to upgrade to Java Web Start 1.5
Now, maybe u have a solution to this problem...
All i want is a solution to let JWS Client download jars only if the user is authenticated by some mecanism....and also support the versioning system.
Also:
Note that the jar names must preserve on the client JWS Cache dir ( i cannot use the same method to pass the JWSCODE when requesting the JARS as when requesting the JNLP).

You need to look into JAAS

Program run in Netbeans but NOT running as jar file

Dear all ,
i hope any help in this problem.
i am writing program to access parallel port i put next files :
1. [ comm.jar + javax.comm.properties ] in
[ C:\Program Files\Java\jdk1.6.0_18\lib ] and [ C:\Program Files\Java\jdk1.6.0_18\jre\lib ]
2. [ win32com.dll ] in [ C:\WINDOWS\system32 ]
when i run application in NetBeans IDE 6.8 work fine and every think is ok
BUT when i produce jar file , generated jar file does not work [GUI appear but can not get ports on PC]
- I try to set Environment Variable as next :
CLASSPATH = .;C:\Program Files\Java\jdk1.6.0_18\lib\comm.jar
also does not work
any tip please ?
Thanks in advance
Nabil

First of all, leave the lib and jre/lib directories of the JRE alone. Never ever touch them again. Remove any jars you have put there yourself, or better yet completely remove and reinstall the JRE to make sure you put it back in a correct state.
After you do that, learn how to properly work with the classpath in both the IDE and the command line.
Netbeans: you define the classpath by adding jars to the project (right click on the libraries node in the project tree to get the appropriate options).
Command line: this depends on if you run a single class, or you invoke an executable jar.
Single class: you use the -cp command line switch to define the classpath
Executable jar: the jar itself defines the classpath in its META-INF/manifest.mf file. The -cp command line switch is ignored.
Since you use Netbeans, you'll get an executable jar so make sure to learn how such a jar is structured.

App runs in Eclipse environment but not from jar file with no error message

When I upgraded my jre to 5.0 my app does not run. After fixing the properties problem I had a few days ago it is now at least compiling and running within Eclpse
However, when I export to a jar file it runs to a certain point and then just goes away with no error message!!! I've narrowed it down to the exact point where it dies but don't understand why it dies and especially gives me no errors whatsoever. It just goes away.
It is creating an instance of a new class when it dies.
Can someone please help me?

Ok, well it doesn't. Anyway, I'm still having the same problems. I can run my jar file to a certain point and then the application just stops. I know this because I've put come message boxes in the application to let me know where in the app the system is.
It always dies when it is instantiating the new class called HeidiFrame; done by:
HeidiFrame heidiFrame = null;
if I put code in between the above line and before the below line, this code will work fine
heidiFrame = new HeidiFrame();
but if I put code after the above line, nothing happens
As I said this all worked fine until I upgraded to Java 1.5
If you look at http://java.sun.com/javase/technologies/compatibility.jsp there are 23 compatibility issues with the new release. We're using xml stuff so that was my first problem and the code wouldn't even compiile. Once I added in libraries, the code compiled and ran beautifully.
However, when creating my jar file so I can deploy this application , I've discovered that the jar file will only run to a certain point, as I've stated previously. So, that's my problem. Not that I can't run it from the command prompt, which I can't, but it's a gui application. I've tried changing things in the classpath file and the manifest to no avail. Nothing changes. The application starts but when it goes to instantiate the HeidiFrame class, which is the class that actually builds the gui it dies and goes bye bye.

How Do I get icons image directory to work in a JAR file?

Yes, I must admit after going through the tutorial and other stuff I am stiil stumped
I have an application that uses the jlfgr icons for the toolbar, and it works fine as long as i actually run it from the directory that it is in.
I would like to put in into a jAr file, and be able to execute it from other places.
I have a Directory named PhoneBook
in that are the classes I use
AddressBook - the main class
PersonEntry - The 'data class'
and various other things like FileFilters.....
inside that directory there are two more:
images - contains all the icon images
Data - where the default 'database' entries are stored.
I use code like this:
     private void fillToolBar( JToolBar bar )
          Dummy = new JButton(new ImageIcon("images/New16.gif"));
          Dummy.setActionCommand("New");
          Dummy.addActionListener(this);
          Dummy.setToolTipText("New");
          bar.add( Dummy );
          // etc etc
to get all the icons into the toolbar
I have made a Jar file that has all the classes and all the directorys with the icons in it
and so the program runs, but does not get the icons for the toolbar, I just get a whole load of 'dud' buttons.....
AS this is the first time i've ever got the GUI to look right rather than just the code functioning properly
I'd like to get the whole thing in a working Jar file
So Could someone show me Step By Step, How I get my classes and images into a Jar file
so that i can from a different directory go
java - jar Phone.jar
and have the GUI come up with all the images, assuming I'm totally thickheaded when it comes to Jar files.?
I also can't get the images to show up if I merely run the 'program' from another directory than the one it is compiled in
I can get the program to run, just not access the images with something like
java -cp blah/blah/blah AddressBook
{the main class is AddressBook }
the data directory can be anywhere as I use a JFileChooser to allow the user to open and save desired files.
I really would appreciate some clear workable help. {though I'm running out of Duke Dollars...}

What you need is a correct path to the directory
inside of the jar. This can be accomplished by adding
a line to your main program like this:
URL
url=myProgram.class.getResource("images/New16.gif");
Dummy = new JButton(new ImageIcon(URL));
where myProgram.class is the name of the class
file that contain the main method.
Hope this helps....
;o)
PS: I don't want your dukes...I got them coming out of
my ears!
O.K, that works thank you.
I put something like:
for all the 'buttons' in the toolbar
URL url = null;
Class ThisClass = this.getClass();
url=ThisClass.getResource("images/New16.gif");
Dummy = new JButton(new ImageIcon(url));
Dummy.setActionCommand("New");
Dummy.addActionListener(this);
Dummy.setToolTipText("New Database");
bar.add( Dummy );
etc for all the rest of the 'buttons'
After Reading the API docs on URL's etc I'm still not sure as to why it works, but it does....
I am able now to place the class files in a jar along with the images and it all works fine
although now I don't quite follow all my code....................
I assume that
url=ThisClass.getResource("images/New16.gif");
returns some sort of 'relative url ' ???
Thanks for the help though.

My JAR file is not working properly!!!

Hi everyone,
I made an application that has a GUI (window). I converted it into a JAR file so I can send it to a friend by email. Then she can run it to generate the output. First, the user has to select a destination to save the .txt file (using JFileChooser). Then enters the inputs (using JTextFields). Clicks "Run" button (Results will be calculated and copied to the file). A Message will appear indicating that the results are copied. The problem is that when I run the application in the IDE (Eclipse) it works fine. But when I convert it into JAR, The moment I click the "Run" button, suddenly the window closes. Please HELP???
Thank you

Sorry guys, but i would like to make things clearer, As I mentioned earlier, What i'm doing is the following: 1) Using the Jfilechooser, save the results into a filename.txt file _[main class in the manifest file (class for the GUI) ]._ 2) Click "run" to write the data to the created file in step 1 [_another class is used to write to file_]. I have a feeling that the problem is related to the manifest main class. What do you think guys?I think your description of the problem is very bad. And I think your idea of making wild guesses is a bad way of diagnosing problems.
First of all. A JFileChooser does not save anything. It just allows the user to select a file to be saved to. So if you thought that the first step was writing anything or creating any file, you're probably wrong. But examining the code would help you understand.
Second, if you're having problems because one class chooses the file name and a second class writes data to it, then you're probably running into the basic beginner problem we see around here all the time of how to communicate data between objects. Again, examining the code might help.
Third, you need to understand what is writing that error message. Examining the code would help there too.
So: stop guessing. Look at the code.I'm still New To Java that's why i find difficulty in problems diagnosis. Regarding the JAR problem, as you mentioned, I used JFileChooser to select a file and (copying data) is the other part. So I will look at the code again.

Unable to run jar file without lib folder containing swing-layout-1.0.jar

I have done my project through NetBeans 5.0. Eventhough I have copied my lib foloder containing swing-layout-1.0.jar inside my project.jar, I am still unable to run my project.jar in other systems, it is creating an error as Could not find the main class. Program will exit. But if I copy the lib foloder containing swing-layout-1.0.jar in the same path as the project.jar, then my project.jar is running.
But I want to give only the project.jar for other users and not also lib foloder containing swing-layout-1.0.jar each time.
Could someone please help me with this.

When you develop GUI applications using the Netbeans you may endup using netbeans specific jar files in your auto generated code.
And when you build jar files with netbeans it copy the third party jar files used in a application in to a lib folder in the same directory as the jar file of your project. And then set a class path entry to those jar files in your project jar file's manifest file.
So if you want to redistribute the package you have to redistribute your jar file and every thing in the lib folder in with the same directory structure.
If you want to change the structure you will have to change the class path to suit the new structure.

How to start a Jar file in another directory?

Hello!
I have 2 questions, hope someone can help me...
1)
I have a GUI which is placed in C:/java/tmp/GUI.java. When I run this program I want it to start runing a JAR file which is placed in d:/tmpdir/app.jar. How do I do this?
2) How can I get the directory a program is running in?
/Clabben

Hello
Yes Rana the main method is placed in GUI.java, and I want this method to start/run the app.jar. The problem is just that these are placed in different directories AND how do I "start/run" the app.jar? The app.jar has also got a main-class. So you can click on it to run it, but I want the GUI.java to do this . Do you, or anyone else, have some code example?

How to link a jar file in a ppt slide

Falied to load Main-Class manifest attribute
c:/documents and settings/desktop/quad.jar
Can any body help me in solving this problem.What is the solution.
Your comments and suggestions are appreciated.
Thanks in advance.
Sravan

I got an Idea!
Falied to load Main-Class manifest attribute
c:/documents and settings/desktop/quad.jar
It's the silly idea of MS to use blanks in foldernames.
It's very silly to accept this.
You may try this:
"c:/documents and settings/desktop/quad.jar"
(with those quotes
or this:
c:/documents\ and\ settings/desktop/quad.jar
(backslashes masking the blanks)
or that:
c:/programs/quad/quad.jar
and create the folder and put the jar there.
It's no good Idea to put something directly into the folder 'Desktop', if this is the representation of your gui-os-desktop.
Instead, put the file somewhere, and create a link in the desktop-folder, to the real location.
So you may clean your desktop from it, but have the original file still in it's location.
You may try a new version and only change the link.
Of course windows-links aren't that powerfull, like linux-links, but we need some windows users, to have some fun, so stay at windows :)
(sorry - couldn't resist).

How to access files in a jar file?

Can anyone tell me how to access a file contained in my jar file?
I have about 15 classes jarred and deployed as an applet. I want to include in the jar file some .gif files to be used as icons in a tree view. Rather than trying to access them locally with all the security headaches this brings, can I not simply jar them as resources and point to them in my code?
Any help much appreciated,
Thanks in advance,
Chris

Hello Chris,
Please read this note taken directly from Sun, from their Java Tutorial/Creating a GUI with Swing/Using Other Swing Features/How to use Icons/Specifying the Image Source (whew!)
Note: Applets are supposed to be able to load images from JAR files.
Currently, however, some browsers can't read images from a JAR file,
although they do successfully get classes from a JAR file.
With our applets, we currently hedge our bets by both putting
the image files in the applet's archive file (the JAR file containing
the applet's class files) and by putting the image files in the file
system on the server.
*/So......Do you want to take a chance?

OutOfMemory Exception while running a JAR file

Hi,
I am working with Java 1.5 and using Eclipse to build a GUI. My application has intensive image loading involved so I set -Xmx inside Eclipse when running the application in debug mode.
However, once a JAR file is exported, I do not know how to specify the heap size required to run the program. Is there a way to ...
1. embed the heap size info inside the JAR file?
2. specify a heap size when running the JAR file?
Thanks in advance.

Heap size is specified by the -Xmx option on the java command. See the java command documentation.

Jar file could not find main class.. I cant see why?

I have read loads of tutorials on this and it should be very straight forward but i STILL cant make a working jar file of my program.. please see if you can see anything wrong with what im doing..
my program is one .java file that compiles perfectly, and is runnable both through eclipse and by using the command prompt.. i made a jar file using both eclipse and the command prompt, and neither worked.. every time i run it by double clicking it i get the error "could not find main class, program will exit". here is the contents of my jar:
CorePackage\IPEmailer.class
CorePackage\IPEmailer$1.class
CorePackage\IPEmailer$SMTPAuthenticator.class
META-INF\MANIFEST.MF
the MANIFEST.MF file contains:
Manifest-Version: 1.0
Class-path: .
Created-By: 1.6.0_02 (Sun Microsystems Inc.)
Main-Class: CorePackage.IPEmailer
(yes there is a blank line at the end)
the class mentioned in 'Main-Class' has a main method that looks like this:
public static void main(String[] args) {
    // TODO Auto-generated method stub
    new IPEmailer();
}the program uses 2 external jar files:
activation.jar
mail.jar
and reads a file called:
ipemailer.ini
and writes a file called:
ip.txt
the program has no GUI and is intended to run 'silently' in the background
please help me understand what is wrong with this

package CorePackage;
import javax.mail.*;
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;

How do I get a jar file to run directly?

I got it to work, as in the jar file runs fine from the command thing. However, I tried getting an html file to run it, but it just wasn't working.
This may be because I only had it incorporate the applet, and there ARE other classes, but I really don't know any html and I wouldn't know how to include those. Also, I don't know if it's an issue, but I don't think it's very plausible to have the applet both display things (my program has a GUI of sorts) and have the main method at the same time, given my program structure.
What can I do? Are there other ways besides creating an html document to run an applet? Is there a way I could include my other classes if that's the problem? I'd really like for it to be able to run in an internet browser- otherwise, my program probably won't reach as many people.

I got it to work, as in the jar file runs fine from

This may be because I only had it incorporate the

Help needed with jar file

hi, first of all sorry if my post is in wrong forum...but my application is done using swing so i am posting this here....and regarding my question...
I have made an GUI using Java swings and my application is working fine. Now i want to make an executable jar file for my GUI. I have read some tutorilas on making jar files and this is what i have done...
i have created a manifest file called mainClass.txt which has
Main-Class: MainWindow ,where MainWindow is my main class name.
Then i ran the jar utility with this command line:
jar cmf mainClass.txt example.jar *.class
With this line, I told jar to create a JAR file (option c) with modifications to the manifest file (option m) as specified within mainClass.txt, naming the JAR file (option f) as example.jar and including everything that matches the pattern *Class
everything is file till now but my problem is ...I have some library files from JFreechart software included in my GUI to generate barcharts..How can i include these library files in my example.jar file..
Kindly help me
Thanks
byee

I had this problem too. I ran my program out of JCreator and it worked flawlessly. I jarred it up into and Executable Jar and I would get a runtime error explaning I have not included the correct libraries.
What I did was look at the error, for example say it said something like:
org.uhoh.PathSys ClassDefNotFound (or something similar to this)
What I did was extract the library that contained that class file. Then in my project file where I kept my classes I made the folder org, then in org I made uhoh. Inside uhoh I copied over PathSys.class.
I hope I addressed the problem you speak of. I am only a novice but this is how I figured it out. If anyone knows a better way let us know =D
