...Simplest way to make Jar Files...

I know there have been numerous questions about jar files and that this has probably been answered before. I am using Forte to develop a program. The program runs fine in Forte, and I used the jar packager to create a jar file. When I double click this file, nothing happens though. I can execute other jar files I have downloaded from the net, but for some reason the ones I create don't work. What is the simplest way to package the classes into a jar file so that I can run my program when I double click it?

I don't know about double-clicking it to run - that involves making a file association (in Windows) to associate a program with a file type - although I assume you've already done this if you doubleclick others and they run.
In the case with your own jars it sounds like you need to add a manifest file with the 'Main-class' attribute set to the name of the class that you want to run from the jar.
eg
Main-class: YourPackage.YourClass
The manifest.mf needs to be in a meta-inf dir inside your jar.
If you open your other jars that do work you will see an example of the manifest.mf file, and the 'Main-class' attribute.
Also - check in the jdk docs in the tools section - this should tell you all you need to know about the 'jar' tool.
Hope this helps,

How to make jar files availabe for deployed EJBs

Hi,
I'm interested on how to make jar files availabe for deployed EJBs.
My EJB is packed in an ear. It uses a util jar. I now just add the jar to the
classpath, but I think that shouldn't be the way. Is there somthing in the admin
console to make jars available or do I have to insert it in the ear file? And
if so, where do I hve to place it?
Thanks
Claudia

Put the util.jar in the ear with your ejb jars - at the same level (i.e. in
the root) - but do not include them in the manifest.xml.
Also each ejb jar that refers to util.jar must have util.jar on its internal
classpath in the manifest.

How to make jar file for this compilation method ?

can any one tell me how to make jar file for this compilation
D:\java\browser\IEInJava>javac -classpath jdic.jar;. IEInJava.java
D:\java\browser\IEInJava>java -cp jdic.jar;. IEInJava
*this is a compile code:-*
D:\java\browser\IEInJava>javac -classpath jdic.jar;. IEInJava.java
*and this is a run code:-*
D:\java\browser\IEInJava>java -cp jdic.jar;. IEInJavanow how make JAR file ?

Assuming IEInJava only uses classes inside the jdic jar, this is one way. D:\java\browser\IEInJava> jar cf yourjar.jar IEInJava.classThen to run it you would use D:\java\browser\IEInJava> java -cp jdic.jar;yourjar.jar IEInJavaAnother way would use the jar manifest file to specify the Main-Class and Class-Path.

Programatic way of updating jar files

Is there a programmatic way of updating jar files (efficiently)? What I am looking for is an equivalent of jar -u option available in JDK 1.3.
The only way I have right now is to create a new jar file, add the new files into this file and then add the entries from the original.
Spawning jar -u ... is also not a desired option.
Thanks in advance,
Bharat

What am looking for is a programmatic way from my Java program to do so without calling jar -u ...
The method I am looking for is using the java.util.zip/java.util.jar packages to acheive the same result as jar -u...

I want to make jar file

i want to make jar files with Konversi.class , how to make it , i hope it like exe file any idea?

Use the jar command to create jar files. The command options are extensive, you should read this tutorial for the details.
http://java.sun.com/docs/books/tutorial/deployment/jar/index.html
If you want to be able to click a jarfile on a Windows or Solaris system and have a program start running, you will need (as a minimum) to add tio the manifest file (inside the jar) the parameter Main-Class: <path+classname> This is all explained in the tutorial.

How to make .jar files executable by double clicking

hi,
I've been trying to make my .jar file created via ANT Tool executable by double clicking it but I'm not being successfull. I looked at the ANT Tool for making manifest.mf and I included most of the attributes listed there and later found that Main-Class attribute is required but its not mentioned in the documentation.
So, I'll be very greatful to receive any suggestions
regards,
Jay

ya I've been doing things the same way mentioned there but it isn't working. here is the code for it:
//All the .class files are in the build directory and the class files are under the package org.home.proj.

<target name="jar" depends="compile" description="Makes CyberStation.jar from the CyberStation code.">
    <mkdir dir="${bin}" />
    <jar jarfile="${bin}/CyberStation.jar" basedir="${build}">
      <exclude name="**/run.bat" />
        <manifest>
       <attribute name="Buily-By" value="${user.name}" />
       <attribute name="Main-Class" value="org.home.proj.CyberSoft" />
         <section name="org/home/proj/CyberSoft.class">
           <attribute name="Sealed" value="false" />
         </section>
     </manifest>
    </jar>
</target>It show the error: Could not find the main class. The program will exit.

Is there a way to add jar file in my program

sorry to botter you, but i really need help for this, i really dont know how to do it. i have my prog taht i want to put in jar file, that cause no problem, but my program isnt fully functionnal because he use a jar file (my driver to acces my database) taht i had mount in forte. but i cant put in in my class file, because i want my jar to be able to run everuwhere on any computer taht have the jre installed. so in resume, i want to add jar file in my program... can i have to add it in my jar file, or decomrpesse it and put the folder like org.postgre.mfileshere... ????? i really dont know
thx to help me

ok If I understood, you need to add a third part Jar
file to your own Jar File App so...
Yes, you can decompress it in a directory tree and
merge it with your application (i.e) if you have a jar
file like this:
br.com.yourApp.util
and a third part jar file like this:
br.com.thirdPart.tools
br.com.thirdPart.util
you will have these directory trees:
br/com/yourApp/util/
br/com/thirdPart/tools/
br/com/thirdPart/util/
then you can marge it in a unique tree:
br/com/yourApp/util/
....../thirdPart/tools/
................/util/
then you can make a new jar file with it...
.....OR YOU CAN ADD THE PATH where your JDBCDrive is
placed to the classpath of your application just using
the -classpath option execution string of you
application, like this:
C:\jreHome\bin\java.exe -jar -classpath
.;C:\someDir\thirdPart.jar yourApp.jar
That's the better way to do it and then everything
will work! :-)

Brazil * * * * *k thx, ill give a try, and give you result later. but can you answer me another question, why when i double click on any jar file executable, sometimes javawa start but do nothing, sometimes they start and said no main class find, sometimes dotn start anymore, and sometimes work perfectly...?? is the jdk taht is not good? i use the last one

How can I make .jar files for applications?

My jar program creates jar files but won't open the program when I double click them. I use the command:
jar cvf *.jar filenames
The jar file is created but won't execute. Can anyone tell me what i am doing wrong?
Thanks
Jiby

Hello !
Well, I had the same problem a week or two ago !
First, in your *.java, don't use any package...I mean, don't do a package of your program (I guess there is a way to make it work with, but it would need a little bit more work...).
Then, with the jar tools, use the command
-jar cf jar_that_you_want_to_create.jar class-that_you_include_in_your_jar.class
With that, a jar will be created, and when you will try to "run" it, it will say that it can not find the main class...
You need a Manifest !
Create a text file MyManifest.text, and write that in your text file :
Main-Class: classname
follow the same as i wrote above. leave a blank after colon and a blank line after the first line like above.
then, well, use tha jar tool again:
-jar umf MyManifest.txt jar-file-you-created.jar
To "run" it, double click on it, or use the java tool:
java -jar jar_you_created.jar
Thanks to Phani, who helped me with that !!

What is the simplest way to make a movie from BufferedImages?

I have a 3d rendered animation from which I can grab BufferedImages of each frame. What is the simplest way I can create a movie from these images?
I've seen the JpegImagesToMovie.java file and not only is it suprisingly overcomplicated, it requires me to change the code so that I can get images from memory rather than from files.
Is there some simple way of creating a movie which requires a few statements? I'm also prepared to use QuickTime for Java. I don't care about the format, since I can just use any video converter to convert it to my desired video format.

I recently came up with a simplified JpegImagesToMovie program. It generates QuickTime movies with a single video track output as a file. Input is a series of jpegs (currently as a list of file names, but easily modified to a take any form of jpeg data.) Since the compression used by the movie is JPEG, if you have an uncompressed image buffer, you'll need to convert that into jpeg data bytes with some quality setting. (Since its a movie file, go with something low if you have a lot of similar images.) This will even run without a full install of jmf--no native code is called (as far as I could tell..)
Here is the source code, sorry about the formatting!
import java.awt.Dimension;
import java.io.File;
import java.io.IOException;
import java.io.RandomAccessFile;
import java.net.URL;
import java.util.Vector;
import javax.media.Buffer;
import javax.media.Format;
import javax.media.MediaLocator;
import javax.media.format.VideoFormat;
import javax.media.protocol.ContentDescriptor;
import javax.media.protocol.FileTypeDescriptor;
import com.sun.media.multiplexer.video.QuicktimeMux;
* This program takes a list of JPEG image files and converts them into a
* QuickTime movie.
* This was based on Sun's JMF Sample Code JpegImagesToMovie.java 1.3 01/03/13
* This code is an attempt to reduce the complexity to demonstrate a very basic
* JPEG file list to movie generator. It does not use a Manager or Processor
* class, so it doesn't need to implement any event listening classes. One
* advantage of this simplified class is that you can just link it with the
* jvm.jar file. (you might also need to track down the com.ms.security library
* stubs, use google. You'll need PermissionID.java and PolicyEngine.java.)
* I tried to get it to generate AVI files without success.
* These output files are could use further compression.
* A Vector of jpeg image paths was one way to do this--the appropriate
* methods can be overwritten to grab images from another source
* --zip file, http, etc.

How to make jar file of application using JMF

Hi
i developed an application which uses JMF it works well during compilation and displays audio and video too.
but after builting jar file it doesn't works.
abdul

Well you've found the root of your problem. It's not necessary the JMF. It's when you make a jar file, you need to include the dependencies. I don't think it' legal to include the JMF in a program you sell or distribute, so be careful there.
However, to include dependencies in jar files is not a hard task. The simplest method is to unjar the dependency and place it at the top or your classpath; then make a jar that includes both your program, and the dependency.
A more long term solution is to use a build system such as ant or maven to create the package using available scripts or plugins. The "Uberjar" plugin for maven comes to mind.

Make "jar" files true executables: allow to pass in params in manifest!!

Right now a jar file's manifest can have a "main-class" which makes the jar truly executable - you can double-click it. The problem is, if you need environment variables, there is no way to pass them in to your main-class' "args."
So why don't we make it so when the jar's manifest is read, that in addition to "main-class" you can have "main-args"?
That would mean everyone would no longer need to bundle java apps with ".exe" or ".bat" or ".sh" files!!! We could have truly Java applications, that are executables!!!
Just package them in a jar, have a main class and the args for it!!
what does everyone think?

what does everyone think?OK, in reading the conversation I realize you need to be more specific. You are interested in passing parameters to the JVM, not to your application. Is this correct?
If so, I understand what you are looking for. But this is handled by the system properties class. If you have some JVM parameter you need to set from the command line, besides memory and other USER ONLY parameters, they should be set by system properties. If they don't show up in system properties, then you need to request that they do.
A jar file is already a cross platform executable of sorts. Why do you think its not?

Is there a way to make photo files on the computer the same as the files in iPhoto?

I have all my photos organized in iPhoto but they are not organized the same way in the photo section of my files. Is there a way to have them show the same files? When ever I need to add a photo to a website I can't find the same one's I have in iPhoto since I'm only able to upload them from the photo file section and not iPhoto.
Thanks!

No and neither is there any need to.
When ever I need to add a photo to a website I can't find the same one's I have in iPhoto since I'm only able to upload them from the photo file section and not iPhoto.
Just need to learn how to use iPhoto:
There are many, many ways to access your files in iPhoto: You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
(Note the above illustration is not a Finder Window. It's the dialogue you get when you go File -> Open)
You can access the Library from the New Message Window in Mail:
There's a similar option in Outlook and many, many other apps. If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
If you want to access the files with iPhoto not running:
For users of 10.6 and later: You can download a free Services component from MacOSXAutomation which will give you access to the iPhoto Library from your Services Menu.
Using the Services Preference Pane you can even create a keyboard shortcut for it.
For Users of 10.4 and 10.5 Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
Other options include:
Drag and Drop: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
File -> Export: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
Show File: a. On iPhoto 09 and earlier: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected. 3.b.
b: On iPhoto 11 and later: Select one of the affected photos in the iPhoto Window and go File -> Reveal in Finder -> Original. A Finder window will pop open with the file already selected.
