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,
MikeHi 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,

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

To install this software which have to use -jar option to install

my question that why we use -jar option to install or to extract the software
can any one clarify my doubt...
thanks in advance

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

How can I add image files to a executable jar file ?
Could you tell me how can I add image files to executable jar file ?
package structure:
../com/Main.class
../images/..Please don't cross post, and read this

Can we make executable jar file which dont have main method?
I have a problem.
With whatever R&D i have done so far my understanding is that in order to create executable jar files i need a main method.
my problem is i have certain MIS reports which are developed in java and deployed through JSP pages...so my java program has no Main Method and only objects of the classes are being called in the JSP pages.
for e.g: i have a java class file BulkSms.class and i make an object of it in the JSP page through which my purpose is achieved by calling various method in the BulkSms through it s objects and there is no main method.
Can i make an executable jar file without a main method and if so please give me a detailed procedure of how to go about it.
i want to make it executable so tht on the click of it the MIS report is displayed from the JSP page.I am completely ignorant of JSPs, but you can not execute a jar or any java application unless you have a main method. It sounds like you need a way to launch the JSP - can't you do this with a browser?

Executable Jar files can't be run without command line
Hello,
A few months ago, I was messing with some executable jar files, but now I can't run them anymore without a batch file or command line, so how do I fix this?
Thanks in advance,
Yves W.

Type
assoc .jarYou should get:
.jar=jarfileIf not, type:
assoc .jar=jarfileNow type:
ftype jarfileYou should get something like this (adjust the path to javaw.exe for your system):
jarfile="C:\Program Files\Java\jre6\bin\javaw.exe" -jar "%1" %*If not, type (adjust the path to javaw.exe for your system):
ftype jarfile="C:\Program Files\Java\jre6\bin\javaw.exe" -jar "%1" %* -
How can I access EJB through executable jar file?
Hello buddies!!
I wonder if anyone could give me an explanation of how accessing EJB through executable jar file?Thanks!!Hi there,
You'll need to install the J2EE SDK on the client and include the <j2ee install dir>\lib\j2ee.jar file in your CLASSPATH along with the Client Jar file that was generated by the deploytool when you deployed the application.
In your client code the Context properties are as follows:
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
p.put(Context.PROVIDER_URL, "iiop://hostname:portnumber");
Context cntx = new InitialContext(p).Hope this helps

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'?>

MHCIYes that was the problem so I have changed the element mainClass to
<mainClass>xxPlotPrint.MHCI.PlotPrintClient</mainClass>
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).
----Batch-file-----
@echo off
java -jar PlotPrint.jar
echo Test Plot and Print Batch-file!
pause
---- out to cmd ----

It's the same problem in all three exceptions (the exactly the same code), however I was a bit to quick this is the line (the line before I process the xml doc :-)
import org.w3c.dom.Element;
responseData = new Vector();
responseData = test_NNE35_SOAP.getXSDdoc();
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 doesn't show images
Hello all,
In my jar file, I have two references to images, which are instantiated as follows:
Icon something = new ImageIcon("image.gif");
However, when I compile an executable JAR file, these images don't show.
I've included the image in the directory which is used for the jar source, and I can't think of any other reasons why it wouldn't work... Does anyone have any ideas?
Thanks
GemmaFirst you need to create an URL to the image inside your jar
String insideJarPath = "/mypackage/images/myImage.jpg"; // starts with a /
Url myImageURL = getClass().getResource(insideJarPath);
Then use that to create your ImageIcon:
ImageIcon myIcon = new ImageIcon(myImageURL);
See API of Class.getResource()
It will tell you that you can work absolute from inside the jar by starting with a "/" for the insideJarPath.
Or you can work relative from the package directory of the class instance calling getClass() by not starting with "/". -

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.
ThanksWell 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. -

Executable JAR file: Could not find the main class.
Hello,
I have a problem with making an executable JAR file.
I have written a JAVA program that consists of five different classes of which User.java is the main class and I have saved a text document with Main-Class: User and a blank line after that.
If I try:
jar cmf MainClass.txt User.jar User.class Beheerder.class Operator.class Manager.class MaakVisueelSchema.class
it makes a executable jar file which actually works! :)
But when the Operator class trys to open the MaakVisueelSchema class the screen stays blank.
I can run MaakVisueelSchema with java MaakVisueelSchema.
So I tried to make an executable JAR that consists only of MaakVisueelSchema, the same way as I did for User:
Main-Class: MaakVisueelSchema
jar cmf MainClass.txt MaakVisueelSchema.jar MaakVisueelSchema.class
Then I get the error message:
Could not find the main class. Program will exit.
from the Java Virtual Machine Launcher.
The big difference between MaakVisueelSchema and the other classes is that MaakVisueelSchema contains a PaintComponent method and an ComponentListener. Is it possible that one of those creates the error?
Can anyone help me with this problem?
Thanks in advance!
Bye!Yes,
I tried:
jar xvf MaakVisueelSchema.jar
and it returns:
META-INF/
META-INF/MANIFEST.MF
MaakVisueelSchema.classN/G. You need to manually create a manifest file in a text editor, have it point to your main class, and enter it in your jar command as an argument. -
Get name of executing jar-file (who-am-i)
Hi,
I'm planning to use a jar-file for a JAVA-application that holds all classes and an additional file with initial values (init.txt). This should allow an easy way to change initial behavior without having to recompile the code (I mean I could put all the initial values directly into the code). So I simply change init.txt and deploy the jar-file.
To achieve this I need a way to find out the name of the jar-file that is currently executing. With that I can open the jar-file from within the code and do the rest (I'm not going to bother you with this ;) ).
In C it was pretty simple, an argv[0] would do it. But how does it work in JAVA? I only have access to the parameters passed to the program.
EXAMPLE:
========
The command line looks like this:
java -jar MyApp.jar
MyApp.jar contains this (among others):
|- MyApp.class
|- init.txt
In this example I need to get the information that I'm "MyApp.jar". I already have the rest of the code so I'm only missing this little thingy.
Thanks beforehands for help.No, you should NOT need the name of your JAR file. You are probably coding it up the wrong way. If what you're after is to be able to read that "init.txt" file, then do so via something like:
InputStream initStream = getClass().getResourceAsStream("/init.txt");
rather than using filename-based API's.
