Jar Dist Package

Hey,
Cutting streight to the question ->
When Java Studio packages a JAR file for dist how do you get it to include the classes necessary to implement JavaMail and the JAF framework?
When I took a working packaged JavaMail interface program and distributed the JAR file the initialization throws an exception unable to find javax.mail etc...
If I put the JAR file back into the IDE it runs fine.

Yeah I am sure that I have all my classpaths set up. I have included all the JAR files from the J2EE development package. So activation.jar and mail.jar are in the library path and it compiles with no dramas. The subsequent JAR file that is produced when distributed or executed outside the IDE fails with javax.mail exception...inside the IDE everythings apples.

Unable to access classes in third party jar files packaged with my ejb.jar

I have packaged some third party jar files in my xxx_ejb.jar file. The third party jar file contains classes that are accessed by some custom classes which are in turn accessed by my bean classes. I get the following error when my custom classes attempt to use any of the classes in one of the third party jar files:
java.lang.NoClassDefFoundError: com/Ostermiller/util/CSVParser
Shouldn't I be able to access classes in jar files that are packaged with my xxx_ejb.jar file? I see the xxx_ejb.jar file as a resource of the application classloader that contains it but I don't see the third party jar files.

As per the Java EE specification, additional JAR files should be packaged on the EAR level. Only WAR files' WEB-INF/lib folder is scanned for JAR files to be added to the classloader.

How to Include libraries (Jar's/Packages/ClassNotFoundException/Classpath)

Ive spent hours looking for a solution, So maby i making a simple human error which i cant find.
Im unfamiliar with using packages.
I have created a program that use the JDBC libary. However i need to distribute this program and keep getting a ClassNotFoundException which is throw by:
String s = "com.mysql.jdbc.Driver";
Class.forName(s);I would like to have the "mysql-connector-java-bin.jar" file inside my main jar file However I think this may be very complex so i assume it would be easier to have it in the same directory as the main jar file.
I create my main jar file with:
jar cmf mainClass.txt Main.jar *.class mysql-connector-java-bin.jarI also jarsigner but i wouldn't expect this to case this problem.
mainClass.txt
Main-Class: MyClassFile
Class-Path: mysql-connector-java-bin.jar
Sealed: trueAny ideas what im doing wrong? or How i could solve this problem?
Do i need to write a program which installs the JDBC on their system?
Is there an easy solution?
Any advice would be greatly appriacted.
Thanks,

ty for the reply
I now create my jar file with:
jar cmf mainClass.txt Main.jar *.classand the "mysql-connector-java-bin.jar" is still in same directory as my main.jar file
Ive also replaced the "mysql-connector-java-bin.jar" to make sure it hasnt been corrupted somehow.
However i still get the same error.
the stackTrace is:

How install my jar+native package for JRE plugin

I cannot figure out how to deploy a plugin consisting of a Java package that calls native code. The calling order is:
Applet -> installed classes in lib/ext/my.jar -> DLL in C:\\WINDOWS\SYSTEM32
I have gotten my plugin to work on Windows IE using the Microsoft JVM, and on Netscape using LiveConnect, and on Mac using MRJ. It also works with stand-alone Java applications. But I cannot get it to work with Applets when I am using the SUN JRE plugin for Java!
I can call the classes in the JAR file but they can't loadLibrary( the DLL ).
I put my JAR file in "C:\Program Files\JavaSoft\JRE\1.3.1_04\lib\ext".
I put my DLL in "C:\WINDOWS\system32" which is in the "java.library.path".
I was hoping that by installing the JAR file in the lib/ext folder that it would elevate its privelege and allow it to call loadLibrary().
I don't want to have to sign each Applet. My plugin is installed using a digital certificate. Once installed it should give regular Applets the ability to call my native code.
I am hoping to simply use a signed Java installer for the plugin that will copy my JAR file and DLL to the right places.
If you use IE or Netscape without the SUN plugin, you can try my plugins here:
http://www.softsynth.com/jsyn/plugins/
http://www.javasonics.com/plugins/
I'm tired of telling people to disable the SUN JRE plugin and enable the Microsoft JVM in order to use my plugins.....
Any ideas?
Thanks,
Phil Burk

I found a solution to my own problem. The problem was that classes in a JAR file installed in the "java.ext.dirs" path could not call System.loadLibrary() when called from an Applet.
The solution was to explictly make use of the priveledged status of the extension classes as follows:
Boolean result = (Boolean)
AccessController.doPrivileged(new PrivilegedAction()
public Object run()
System.loadLibrary("mylib");
return null;

Java Jars And Packages

I was just wondering if there was a way to create a jar file containing a custom library of classes that you could import packages from? I know you can setup a jar so that it will automatically run a program when you double click it - but is there a way to import files from it? I've tried looking up the tutorials on it on the Sun website - but I couldn't find anything directly on this question.

However, note that if you use a library jar from an executable jar you need the path to the library jar in the Class-Path: property of the executable's jar's manifest, command line or environmental class path is ignored for executable jars.

External Jar files packaged with the Application Jar.

Hello Friends,
I have a Java class 'Config.java' with a package a.b.c
This class requires a third party Jar 'new.jar'. I place this Jar file in the parent directory of the package.
So I can compile the Config.java with classpath as '.'
This works fine.
Now while packaging them, I create a mymanifest.mf file with following contents
Main-Class: a.b.c.Config
Class-Path: . new.jar
and issue the command
jar -cvmf mymanifest.mf myjar.jar *
This creates a jar file with appropriate manifest information and heirarchy (since the included third party jar is in the same directory)
When I run the Jar by issuing the command
java -jar myjar.jar
It gives me an error, NoClassDefFound for a class inside the included third party jar.
I have gone through some of the other queries posted in this forum and through Sun's articles for creating Jar files.
I have taken care of all the minute things involved in writing the manifest file, etc.
I dont understand why such a simple application gives me a problem.
Am I still missing something ?
Regards,
Ravi

I had the same problem. But I solve it.. The thing that you have to do is:
create another directory in your project application directory let's say your project directory is Project. such as Project / lib.
then put external jars in lib directory.
The last thing you have to do :
change your manifest file like that
Main-Class : mainclass
Class-Path : lib/externaljar1.jar lib/externaljar2.jar
I don't know you ever deal with manifest files before but there can be very stupid errors while you create .
i.e there should be a space between ":" and mainclass name you shoul use "/" not "\" etc.
I think it will work for you.

Problems with JApplet, jar-Archive, packages and IE5

Hello!
I have a problem with a JApplet and Internet Explorer 5. I made a jar archive of my classes. The classes are
members of a package. The jar archive also contains images.
The structure of the archive:
com/mycomp/myapp/DemoApplication.class
com/mycomp/myapp/DemoApplet.class
<more classes>
com/mycomp/myapp/images/hp_logo.gif
com/mycomp/myapp/images/test.gif
<more images>
The archive is stored locally in a directory which contains also the html file.
I used the sdk 1.3.1 to compile the classes.
My problem: when I start the html file on NT with IE5, I get the error message below:
I try to create a label containing an icon with:
topLabel.setIcon(new javax.swing.ImageIcon(getClass().getResource("images"+fs+"hp_logo.gif")));It works on Sun with Netscape 4.67 and SDK 1.3.1 installed.
Should I move the images directory inside the jar archive to another place or is the html code not correct?
The error message:

Including other JARs when packaging

Hello,
I have read the SUN tutorial on how to package my application, which I was able to do and execute fine. The problem is, in my application I use several database connection jar files, such as mysql-connector-java-5.0.4-bin.jar (MySQL) and jt400.jar (AS/400). When I try to do something in my application that uses one of these jar files, such as when I try to log in (uses a MySQL connection), I receive the following error:
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
My application works fine if its not packaged, but when it is, I receive this error. I tried putting the jar files in the package folder, but that did not help. I tried setting my classpath to those files in the package folder, that as well did nothing.
Could anyone help, or point me in the right direction?
Thank you.

But... it still requires me to extract the lib folder
out of the jar, and keep it in the same directory as
my main jar for it to read. I just want to be able
to double click on it and have it launch, without
needing to extract anything..That's the idea. You don't need to extract anything if you distribute your entire directory rather than trying to pack those other JAR files into your JAR file. The idea is that they're separate and your JAR file is linked to them. With your command
jar ... lib/*.jar
You're actually adding the JAR files to yours, rather than leaving them outside of it and just bundling everything up and distributing it. There's good reason to leave those JAR files separate. For example, when your MySQL driver gets updated you can distribute that single JAR file as an update (and perhaps your own if your code changed) rather than having to bundle everything up again and distribute the entire thing.

Executable jar with package

Hello,
I have been making jar files and using the manif.txt. But today, I have the need to create a executable jar with a package.
eg: com.skp.util
I typed in my manifest.txt
Main-Class: com.skp.util.classname
(and made sure my return was there).
Then I jar cmf manifest.txt test.jar classname.class
But when I run it, I get a class not found error:
Thanks,
What does one need to do differently to get packages to work.

I tried that with a very simple class, but it does not appear to work?
When you run the jar do you use the package name there?
Here is all I have, it is simple:
mymanif.txt
Main-Class: com/ddi/ags/convert/showargs
Here is how I am crating the jar
jar cmf mymanif.txt test.jar showargs.class
And I run it like this:
java -jar test.jar
And get this error:
$ java -jar test.jar
Exception in thread "main" java.lang.NoClassDefFoundError: com/ddi/ags/convert/s
howargs
And here is the class:
package com.ddi.ags.convert;
import java.io.*;
import java.util.*;
public class showargs
File log_file = new File("C:/testlog.txt");
public static void main(String[] args) throws Exception {
     if (args.length < 1)
     System.out.println("args are less than one.");
     System.exit(1);
     } else {
     FileWriter writeit = new FileWriter("C:/testlog.txt", true);
     for (int i = 0; i < args.length; i++) {
          writeit.write(args[i] + "\n");
          System.out.println(args);
     writeit.close();
     System.out.println("all done with testing.");

How to install OS X .dist packages?

I've downloaded a number of recent OSX updates that include .dist files. How can I use ARD to distribute these updates to the Macs on our network?
Thanks

ARD, to my knowledge, cannot push out anything other than .pkg and some .mpkg files.
What updates are you getting that are coming in .dist? .dist files are distribution scripts, not the updates themselves, and I've never seen them downloaded outside of a .pkg or other installer file though I haven't been having my system keep installers downloaded through Software Update so perhaps things have changed and I haven't noticed.
Anyway, you may need to download the standalone installer distributions so that you can get .pkg files for use with ARD.

Help! How to create Jar file for a packaged class?

Hi!
I am new in jar complexities. I made a swing frame that just prompts a JOptionPane when executed. I accomplished the same using jar without packaging my class SwingTest.
But when i package it, it doesn't run. Can any one tell me how to make jar file of packaged classes and include images in the jar files too!
Really Thanx!

Call the Jar from the commandline to see the exceptions thrown.
java -jar <jarFileName> <className>

Internal JAR package loading???

Ok I hate having to come to forums and bother other people,
but hopefully someone will know and be able to aid me in some way...
It's driving me absolutely insane...
Alright I've made an application. Basic application that display Hello World
in a JLabel. That's all. But here the catch, it uses the GUI jar's from
netbeans. Java Studio 8 uses them, and apparently they dont come
standard with java, or i wouldnt be here...
So goal = Somehow JAR and load the required packages with the main application for use with JNLP web start.
I have tried editing the MANIFEST.MF in many ways to get the
CLASSPATH to load the JAR packages(Which happen to be:AbsoluteLayout.jar),
but no luck.... I have also tried using Certificates to be able to externally
load the package i need, and no luck...
C:/Web_Server/test.jnlp // Open's Java Program in Web Start
|---->C:/Web_Server/test.jar // The Main Program
|---->C:/Web_Server/lib //External Package Directory(holds AbsoluteLAyout)
|-------->C:/Web_Server/lib/AbsoluteLayout.jar // the package i need to run test.jarNow get this... It will load successfully if I run the JAR file, but if i try the web start JNLP, it brings back:java.lang.NoClassDefFoundError: org/jdesktop/layout/GroupLayout%GroupThis is because it's not loading the lib/AbsoluteLayout.jar.
If I delete the lib folder and attempt loading the JNLP with the lib packages in the test.jar, it brings back "noMainClassDefError".
------------------ In-Short ------------------
For those who didnt understand/read the above:
I Made an Application w/ Java Studio 8.1
Cannot distribute it to Web using JNLP.
Because:
1.) Classpath in Manifest only loads outside test.JAR(and certificates dont help)
2.) Java is being a cunt.
Help is GREATLY appreciated, im about to pop a few blood vessels.

haha i found my own answer on accident while browsing for a different problem....

Difference between jar file and package?

What is difference between a package and jar?
Is a jar a package? or is package jar?
If I say
package pink;
does it mean pink is folder or jar?
what if I say import pink.rose;
does it import jar file with the rose class inside it?

These two concepts are unrelated. A jar file is nothing more than a zip file of class files and other related resources, which you can use to 'bundle' your application for ease of deployment. Th use of zip files is not mandatory.
Packages on the other hand, are a means of 'packaging' parts of an application or library in their own namespace, generally for reasons program structure, and to avoid naming collisions. A bunch of classes in a package will be compiled into a bunch of class files, on a one-to-onwe basis (one file per class).
You may chose to 'bundle' those and other classes into a jar file.

Can't run JavaFX app as a jar file from command line

I'm trying to build a JavaFX app from scratch (that is, by including the jar file from the JavaFX SDK rather than by using the special JavaFX project type from NetBeans). It runs fine in NetBeans. However, when I try to launch it as a jar file from the command line (using "java -jar dist\TestApp") I get the following. Has anybody seen this before, and if so how can I fix it?:

Unsatisfied link means that Java is trying to access a native library, but it cannot be found. As to why this error is being thrown, here is my guess:
If you open up one of the sample jars with a zip viewer, you will see that the Manifest file has the following entries:
>
Manifest-Version: 1.0
JavaFX-Version: 2.0
implementation-vendor: Oracle
implementation-title: BrickBreaker
implementation-version: 1.0
JavaFX-Application-Class: brickbreaker.Main
Created-By: JavaFX Packager
Main-Class: com/javafx/main/Main
>
In other words, a JavaFX project works a bit differently than a normal Java project. com/javafx/main/Main is used as the Main class and your "Main" class is called later.
If you are trying to build this from a normal Java project, then com/javafx/main/Main will not be created and it will call your Main class right away. Thus, whatever setup is needed to run JavaFX will not occur.
