Executing JAR Files Windows 98 and XP

Hey can someone please help me.
I made an executable jar file the extract contents of a jar file. In windows XP it runs fine, however in Widnows 98 it does not, has anyone come across this problem? Any info would be greatly appreciated.
Thanks

Well When I try, On a windows XP machine it shows the progress bar I made, and extracts all the files to the c drive. On Windows 98 It shows the progress bar but will not extract the files to the c: drive folder.
The program simply gets all the files that are within the jar file, and puts their names in a Vector, then takes the names from the Vector and Extrats the ones that need to be extracted.
Any other Ideas, I know this sounds very wacky thats why I am in need of help.
Thanks for the ideas.

[b]Simple Deploy problem- making an Executable JAR File ...PLEASE HELP [/b]

Hi all,
I Trying to deploy a simple J2SE app by making an Executable JAR File, however I don'r understand how to add a valid value to the Main Class field.
I followed the following description within Jdev, after creating a Deployment Profile:
Deploying an Executable JAR File
You can make your simple archive or J2EE Client Module into an executable JAR file that you can launch with the java command.
To deploy an executable JAR file:
1) Select and right-click the simple archive or client icon in the Navigator to display the context menu.
2) Choose Properties.
3) Click JAR Options in the tree.
4) Select Include Manifest File (META-INF/MANIFEST.MF).
5) In the Main Class field, enter the fully qualified name of the application class that is to be invoked.
7) Click OK.
8) Launch the executable JAR file from the command line:
java -jar myapp.jar
where myapp represents your JAR file name.
Like I said it's in 5) I'm doing something worng
My deploy-file (PlotPrint.deploy) looks the following:
<?xml version = '1.0' encoding = 'windows-1252'?>

But now another probem has occured, since I get the following error when run the jar-file (When I run the app from within Jdev there are no warnings or errors).

Element elements = ( (org.w3c.dom.Element)responseData.elementAt(0) ); (line 42)
Please help I don't understad why I receive this exception, since I included the xmlparserv2.jar file, and don't even have a workaround :-(

Executable JAR file and subdirectories, locale...

Hi:
I have created an executable jar file. In my program, I have to display an icon in which I stored in a subdirectory. This subdirectory is also archived into the jar file. However, as the application runs, it can't find the icon! I have to seperately create a subdirectory (with the same name and structure as the archived directory) for my program to display the icon properly! Does anybody know how I can use the archived subdirectory directly?
Also, the executable jar file has a problem of using the proper locale... Does anyone know how to get around this?
Thanx in advance for helping me out = )

Thanx! It worked!
Does anyone know the answer to my second problem, namely, using the correct locale to display characters? When I run the application on the unarchived class file it works fine. However, when I run the application double-clicking the executable jar file icon, the characters are displayed incorrectly, which I assume to be problem with the locale...

Executable jar files and manifest file

Hi,
I have the following files in a folder named: Test
a.jar
b.jar
c.jar
Driver.class
Driver.mf
Here, MainClass is the main executable class that uses a,band c.jar files. This is how my MainClass.mf file looks:
Manifest-Version: 1.0
Main-Class: Driver
Class-Path: a.jar b.jar c.jar
Now I use the following command to make one executable jar file:
jar cmf Driver.mf DriverMain.jar *
It creates an executable jar file named : DriverMain.jar
Now I copy the executable jar file (DriverMain.jar) into a different folder named: RunTest
and double click it, doesn't work.
my question is:
what am I doing wrong? Any special characters needed in my Driver.mf file (space/newline/etc)?
What I am trying to get is: One execuatble jar file so I can just double click to run it, and that single executable jar file will have all the necessary jars in it (i.e. a.jar, b.jar, c.jar in this case)
Anyone please help!
Thanks
-Ron

Rony,
Sorry to disappoint, but you can not use embeded jar/zip files within an executable jar. The JDK sadly for some reason decided this was not a useful idea, so developers like me who want to distribute plugins with thier own dependencies have one of two choices. You either have to unzip the jar file that contains the embeded jars to a directory, then run your primary exectuable jar, OR you have to write a custom classloader that your "launcher" creates then loads the embeded jar files.
The best thing to do is either jar up a, b, c and driver into one jar, so that it works, if you can legally do this. A lot of 3rd party libraries may not allow this per their license. Otherwise, another choice is to use a free installer or buy an installer that allows you to distribute a single exectuable installer program that will properly create the dir structure you need.
As for the way it works, if you declare:
Class-Path: a.jar b.jar c.jar
the JAR loader code in the JDK looks in the root dir where your application was started for a/b/c jar files. They have to be on disk.
If you want to place them in /lib, for example, you would havd a jar file like:
Driver.class
Driver.mf
lib/a.jar
lib/b.jar
lib/c.jar
When unzipped, your "root" dir would look exactly like the above, and your manifest would have Class-Path using ./lib/a.jar ./lib/b.jar ./lib/c.jar
Anyway, there thus far isn't any way around this issue of embeding jar files in an executable jar file. You MIGHT be able to not specify any classpath, then in your Driver.class, create a new custom classloader that dervies from URLClassLoader, but in the findClass(), you get a ref to the .jar file that the classloader class is inside of, and from that use it to find the lib/*.jar files and add them to the classpath. For this to work, however, your Driver.class code should ALSO be contained in an embeded jar file that is loaded by this custom loader. The only thing Driver.class would contain (and I would rename it to something like Launcher) is the code to create the custom classloader.
It's fun stuff, but a little bit of work to make it work. You can infact make it work! I may yet one day take our plugin engine custom loader and create a way for this to work!

Executable Jar files with Oracle drivers and Oracle classes

I have a program which works perfectly that is used to do file
maintenace on an oracle table. Now I am ready to make this into
an executable jar file. I know how to do this, but my problem is
now how do I get the Oracle classes into my jar? I think they
are all in classes12.zip, but just adding classes12.zip into the
jar doesnt work. I still get an error when running the program
that says it can't find oracle.jdbc.drivers.oracledriver.
You can use the jar command to add all classes in a directory,
but this doesnt work either.
Has anyone out there ever done this? Please help if you know how
to do this. How do you put the oracle classes into you
executable jar file?
Wah!!!

Me again. I forgot to mention that I am only using Java. We
don't have Oracle forms or jdeveloper. This is just straight
java. Everything worked until I tried to executable jar creation.

Why -jar option used to install a software which is in executable jar file?

Hi all,
i have a query, i have a generic installer which is used to install the oracle weblogic 10.3 software in unix platform(i.e., which is in .jar extension) which is executable jar file.
To install this software which have to use -jar option to install
java -jar net_server<version>_generic.jar
my question that why we use -jar option to install or to extract the software
can any one clarify my doubt...
thanks in advance

According to the Jar Guide (http://java.sun.com/j2se/1.4.2/docs/guide/jar/jarGuide.html)
Executable Jar Files
On Microsoft Windows systems, the Java 2 Runtime Environment's installation program will register a default association for Jar files so that double-clicking a Jar file on the desktop will automatically run it with javaw -jar. Dependent extensions bundled with the application will also be loaded automatically. This feature makes the end-user runtime environment easier to use on Microsoft Windows systems.
The Solaris 2.6 kernel has already been extended to recognize the special "magic" number that identifies a Jar file, and to invoke java -jar on such a Jar file as if it were a native Solaris executable. A application packaged in a Jar file can thus be executed directly from the command line or by clicking an icon on the CDE desktop.
Despite that every JAR file can be executed as a program if and only if the META-INF/Manifest.mf contains the Main-Class tag. This done through java -jar jarfile.jar

Why i can't execute jar files

Greetings
I read that jar files are executable unpon clicking them, but with me it do nothing.
right now i'm using the command prompt to decompress jar files
jar -xf jarfile.jar
i have windows xp professional with j2sdk1.4.1

You can execute JAR files by double-clicking them if the JAR files have an appropriate manifest and your file associations are set correctly (i.e. make sure you open JAR files with JAVAW.EXE). You can learn more about the manifest here:

Can't Execute JAR file deployed from JDev 903

Hi Everyone:
I took the Oracle beginning Java class, and got a copy of JDeveloper 9, and started in on a project. The task was to create a small module that will allow users with no direct SQL access to change their Oracle passwords. The good news is that it runs great from within JDev; it catches exceptions cleanly, it handles multiple databases with no problems. The bad news is that I cannot get it to run from a batch file or command line (client is Windows). I have run 'setvars', I have copied the CLASSPATH from the run window in JDev, all to no avail.
I am trying to deploy the app as an executable jar file. It's not meant to be an applet, because of the security implications.
I would gladly RTFM, but the FM's that I have gloss over the deployment step in Jdev. I figure it's something obvious, but I just cannot figure it out.
Any suggestions? Help a newbie...
Thanks,
Mike

Hi Mike,
I suggest you take a look at the log window of JDev, when you've successfully run your project.
If the log window is not displayed, go to View | Log.
Cut the command line, invoking javaw.exe, and paste it into your favorite editor.
Change javaw.exe into java.exe, save your file as a bat file, go in a DOS console, and run the bat file.
Let me know if it fixes your problem.
Thanks,

Cannot make executable jar file for swt application

hi to all!!! i have started learning swt library and it seems nice to me, but i have one problem, i cannot run my application. The problem is that i cannot make executable jar for it.
i'm using ecilpse_3.1.2 and have pluggined the visual editor for swt! yesterday i found one topic where was described the process of making the swt executable jar, i followed the instructions in the topic, but didn't resolve my problem, so if anybody knows how to achieve this , please help!!!!!!
the instructions in the mentioned topic are :
1. Make sure the SWT jar file is included in the Eclipse project build path
a. Download the standalone SWT jar file from eclipse.org even if you already have the ones that come with Eclipse. It is called ?swt.jar? and you will package it with the executable JAR. Make sure it is the same version of SWT that you used to make your program.
b. In Eclipse, import swt.jar via Project Properties::Java Build Path::Libraries::Add External JARs. (Make sure to include the source .zip file). Also make sure to select the swt package in the ?Order and Export? tab.
c. At this point, you should be able to compile and run your SWT application in the Eclipse SDK.
2. Do a standard Eclipse jar file export
a. Right click on the main .java project file and select ?Export??.
b. Choose ?JAR File? from the list.
c. Select the relevant packages and .classpath and .project resource files
d. Make sure ?Export generated class files and resources? is selected and browse to the location where you want the JAR file to be created.
e. Specify ?Generate the manifest file? and don?t seal the JAR or any packages. Choose the class containing the main method as the ?Main class?.
3. Change the manifest file
a. Navigate to the JAR file you created and open it with WinZip.
b. Open the MANIFEST.MF file inside and copy the contents.
c. Create a new file called ?MANIFEST.MF? and paste in the contents of the old manifest file.
d. Add the line ?Class-Path: <swt jar file path>?. For simplicity, you can just keep a copy of the swt.jar file in the same folder as the executable jar, in which case, the line is ?Class-Path: swt.jar?. Make sure there is a carriage return after the last line in the manifest file, or that line will not be parsed.
4. Replace the manifest file
a. Make sure the manifest file and the executable jar are in the same folder.
b. Open the command prompt and navigate to the containing folder.
c. Enter the command ?jar umf MANIFEST.MF <executable jar name>? to update the manifest file with the class path information.
5. Package the JAR with SWT files
a. Put the updated executable JAR file, swt.jar, and the associate DLL in the same folder. The DLL can be pulled out of swt.jar and should have a name like ?swt-win32-####.dll? on Windows.
b. The JAR file should now successfully execute. On Windows, you can usually just double click the JAR file in explorer and it will open. If that does not work, the command ?java ?jar <executable jar name>? on the command line has the same effect.
but a few steps aren't exact for me , for example : first, which jar i have to include in build path : downloaded or from plugins folder, second
i have to incude source.zip too??? but it is only in downloaded zip file which includes both swt.jar and src.zip, and finally can anyone clarify next :
"5. Package the JAR with SWT files
a. Put the updated executable JAR file, swt.jar, and the associate DLL in the same folder. The DLL can be pulled out of swt.jar and should have a name like ?swt-win32-####.dll? on Windows."
what does this mean, put these in folder or make jar from them????

wolve634 wrote:
but a few steps aren't exact for me , for example : first, which jar i have to include in build path : downloaded or from plugins folder, secondTry it both ways. If neither works, then ask again. In a suitable forum, though. An Eclipse forum or an SWT forum or something related to where you got those instructions would make a lot more sense than asking here.
i have to incude source.zip too???No, of course you don't have to distribute the source code.
a. Put the updated executable JAR file, swt.jar, and the associate DLL in the same folder. The DLL can be pulled out of swt.jar and should have a name like ?swt-win32-####.dll? on Windows."
what does this mean, put these in folder or make jar from them????It says "Put (them) in the same folder". You're asking whether that means to put them in a folder? Yes, it does.

How to execute jar file

Dear all,
1. I am trying to import a .jar file and execute (run) in eclipse. I know it can be done from command window by java -jar z.jar . But I am supposed to do it in eclipse . I would appreciate your help.
2. jar files are supposed to be executable. But in my premium window vista as well as in XP it doesnot run by double click though I have given the class path. How can it be done?

jar files are supposed to be executable.Only if you have a file association for the extension.
Presumably when you double-click the .jar file, Windows pops up the "Open With" dialog. Select from the list or click Browse... and navigate to java.exe (javaw.exe if you are only going to run GUI applications) in the jre/bin folder. Select "Always use the selected program to open this kind of file" and optionally enter a description for the file type before clicking OK.
Note that a console application opened in this way may flash the console window and terminate i.e. the console will NOT remain open after the application dies.
I don't use Eclipse so I can't help on your other question.

Extract contents of a .Jar file or executable jar file

I have an executable Jar file.. Is there anyway that I can see the contents of this file.. the code in it..
I have read some tutorials on how to extract .jar files but the question is where do i execute these commands.. is it on the command window or somewhere else.
Can anyone help me plz????????

but the question is where do i execute
these commands.. is it on the command window or
somewhere else.
If you're using windows OS, you can do execute the
command in dos promt
and if you're using linux, you execute it in the
Terminal/Console or double click on the file name in
the
Knoqueror, you can see the contents.Konqueror file manager,you can see the contents.

Associating executable Jar files w/ appropriate program

Hi, I'm kinda new to java but this question is more OS related I think. I made a GUI program that reads / writes files and does some other stuff, I compiled it, then made it into an Executable JAR file. I put the file on my dektop w/ the required resource file (contains the read files) and then I double-click it and lo and behold Win-Ace(R) popps up. I right-clicked on the executable jar file, associated it with JAVAW, double-clicked again and it worked. So i guess my question is, is there a way that it will automatically associate itself with the right program so when I give this program to other people, they won't have to associate it the same way?
Anyhelp would be greatly appriciated!

No, becourse even if java could do that it would make sence becourse to run the jar it must be associated with javaw.
But you could try to create a .reg file (registry file) that associate jar with javaw, when somebody runs the reg file it associate jar with javaw.
But I think you should make different reg files for different windows versions (not sure about that).
I don't have experience with how to write reg files but you just google.
But I should try it out on your own windows, you could install windows on another partion and try it out on that one (first make a image with norton gost or something so if something goes wrong you can fastly get back to the old state).
But you can also export your registry to a file so you can put the old registry back if somethings goes wrong.
Use these tips on you own risk!!!

A few questions about executable Jar files

Hi,
I have to make an a tutorial system and was going to make it using applets embedded in webpages. This approach causes certain limitations so decided to make it using JPanels that open up as windows on the users computer.
I intend on compressing all the files (java, images, sound etc) within a Jar file and would like a few questions answering.
1. How would I make an executable Jar file that when clicked on will load the program on the users computer. Is there some software to do it for me or do I have to do it from the command prompt?
2. Is using a Jar file the best approach or is there a better way to get my java program to run on other peoples pc's
3. If I create an executable Jar file on windows xp, will it run on a Linux machine?
Cheers

1. How would I make an executable Jar file that when clicked on will load the program on the users computer. Is there some software to do it for me or do I have to do it from the command prompt?The SDK contains all the tools you need. Use the jar command. To make your jar executable, include a manifest file that references your main class.
2. Is using a Jar file the best approach or is there a better way to get my java program to run on other peoples pc'sA jar will work just fine.
3. If I create an executable Jar file on windows xp, will it run on a Linux machine?Yes.

Running executable JARs from Windows

Hi!
I have this executable JAR file with no problems for running it from the Windows console using the "java -jar jarfile" command. But if I double click the same JAR file in Windows explorer I get a "Main class not found" error. Does anyone know what's happening here ?
Thanks in advance

I think the following varies somewhat depending on which Windows you are using. On Win 2000 in a Windows folder, select Tools menu, Folder Options and select File Types. Then select JAR and click on Advanced. Under Actions, there select "open" and click on Edit. For the Application, you should see something like "C:\Program Files\Java\j2re1.4.1_01\bin\javaw.exe" -jar "%1" %*
