Can't get Jar to execute

I have an application that I'm trying to create a Jar file so I can just execute the jar to run it. When I try to run it with "javaw JHandicap.jar" it says it can't find the main class. Nothing happens when double clicking the jar. Of course if i put in into the classpath it then finds all the classes. I have another program that works ok from the jar without being in the classpath, which I created a while ago, but it only has one class, so I'm guessing that's my problem.
For this program the main class is called JHandicap.
There is another class called DateComboBox.
And one more for WinClosing.
There are also a bunch of classes with $'s, like DateComboBox$1.class, but I'm not sure I understand the importance of those being included or whether they get created when it is run.
I created the Manifest in a couple different ways:
Try1:
Manifest-Version: 1.0
Main-Class: JHandicap
Created-By: James Pifer
Name: JHandicap.class
Java-Bean: False
Try 2:
Main-Class: JHandicap
try 3:
Main-Class: JHandicap.class
None of these worked. Do I include the other classes in the Manifest too? If so, how?
Can Anyone tell me what I'm doing wrong?
Do I create the jar with only the main class files or should I do *.class to include all the $ ones too. I've tried both ways.
Any help is appreciated.
James

My understanding is that the more recent JRE's can run JAR files by double clicking them. I know 1.3+ does, not sure about 1.2.
Anyway, I created my jar like this:
jar cfm myjar.jar Manifest.mf *.class
This will add all the classes in the current directory to the myjar.jar file. Make sure all your class files are in that directory, unless they are in your regular classpath.
My Manifest.mf has one line in it:
Main-Class: classname
Make sure you have a carriage return after this line. That's it, you should be able to double click on it. Hopefully I haven't missed anything.
HTH,
James

How can I get Firefox to execute html code in a text file?

I used Notepad to create a text file, markup.html, that contains html code. How can I get Firefox to execute this code?
Also, how can I use the <script> tag in the html code using the src attribute to execute code in a file written in Javascript?

First guess is that you did not use an .html extension on the file. The file may well be ''name.html.txt''

How can I get firefox to execute perl scripts from local files

I have created perl scripts on my local host (file type ".pl").
In MS Windows I have associated that type to a perl interpreter installed on my local host.
IE allows me to create links to them and to execute them (after asking for permission).
How can I get firefox to do the same? It doesn't seem to allow me to add application types, only to change those that are already defined. As a result, in firefox, they just show up as text, instead of being executed.

First guess is that you did not use an .html extension on the file. The file may well be ''name.html.txt''

Can't get iTunes to execute.

I've recently bought an iPod Nano and installed the iTunes software v5. When I try to execute iTunes, I get the agreement screen and an error message stating:
The folder "iTunes" cannot be found or created and is required.
The default location for this folder is inside the "My Music" folder.

Can I get jar version from class run from within jar ?

I am launching a number of applets from a single jar file. I want to display jar file version on initial applet. I would ideally like the applet to be able to determine from the jar file which it was part of what version it is . Is this possible ?
Applets are swing based & I'm using java plugin

if your jar file has a manifest that specifies the version number, you can use java.util.jar.JarFile to get the information. Other wise, you would just have to induce it based upon the file attributes of the jar file, using java.io. Remember that applets can not, by default, read the local file system, so you might have to use signed applets.

Can't get JAR file to work

I am currently having problems getting the JAR file for my program to work properly. Here is what I'm doing in creating it and trying to run it:
1.I create the JAR file with the command "jar cf myjar.jar *.class"
2.I create a manifest file to point to the main class which contains only the line "Main-Class: MainClass". This is WITHOUT the .class extension
3.I update the manifest for the jar archive with the command:"jar umf textfile myjar.jar"
4.I try to run the app with the command "java -jar myjar.jar" but this only gives me an error that says "Failed to load Main-Class manifest attribute from
myjar.jar"
Am I doing something wrong here? I've tried to make my steps as close as possible to those that I read in the tutorials, but it's still not coming out for some reason. My computer does recognize the file as a JAR though since it made an icon of a JAR file for it. Please note I made up names for both my jarfile and main class file for privacy reasons, but I do not think the specific names would make much of a difference in this as they contain no special characters or anything in the file names.

Hmm....I tried both of your tips javagalaxy and tsith by making the file look as javagalaxy posted as well as renaming it to "manifest.mf" and putting it in a "META-INF" folder that is in the same directory as all my .class files. I also made sure I hit Enter twice so that there was a blank line between the Main-Class line of the file. When i run the command it displayed "added manifest" as well as all the class names that I needed to be in the jar file including the main one that I'm trying to invoke. Despite all of that I'm still getting the same error that it can't load the main-class attribute from the jar file when using the command "java -jar myjar.jar" =/. I'm not really sure what went wrong. I tried deleting the extra line so that the cursor was flashing right below the Main-Class line, but that didn't change anything when I re-ran the commands. Did I do something else wrong in the manifest file? Thanks for your help so far! This is some complicated stuff the first time one tries it.

Can't get transitions to execute

Hi folks,
I'm building my first Flex app, which is a typical simple quiz. Intro state, string of questions, then a result.
I'm stuck right now in that my transitions are not running. I suspect it has something to do with the fact that I extended the Application class and typed my main application mxml file to that class so that I could keep Actionscript separate from MXML in two separate files. The app will switch states successfully but it won't run the transition effects on a state change, and so my endEffect event is not firing...
It may be that I have something else wrong altogether.
Here is the application MXML file:

Can anyone point out what I've got wrong that could cause the Transitions not to work? I thought they were simply supposed to execute on a state change from A to B, for which you've indicated set up a Transition from state A to B.
Many thanks!

Ok, I finally figured out what was wrong. I was missing the concept that you had to specify a target element in the effect definition in your transition upon which the transition would play. Transition plays now.

How can i get a java executable (*.class) run on a web browser?

I have created a simple appilcation in java and i would like to view it through a web browser.
In order to do so, do i need to use an application server or just a web server?
Can you come up with another solution to solve my problem(view the java application through the web)?
Thank you in advance.

If it HAS to be an application (perhaps something you have already written and now need to distribute), then Java Web Start may be an option.
What is your user base? How many people will be using it? In what environment? How frequently will they use your app? I think you mentioned that it needs to read files. Is that on the user's machine?
You may be able to create an applet version of your application using the same logic but subclassing some of the components to allow for remote login etc.

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.

Can't get a jar file to work

Hi All,
I have a moronic question. I have a simple jar file called xmlpowertoolkit.jar and I can't get any of the classes in it imported into my simple console app.
I unpacked the jar file to look at the namespace hierarchy since I have no documentation with this jar file. It came out like this:
xmlpowertoolkit\com\sabre\xmlpowertoolkit\
... then a bunch of classes in this directory. Specifically, there is a class called XMLPowerToolKit_Services that I need to use. Here is a typical constructor call for this class:
XMLPowerToolKit_Services myvar = new XMLPowerToolKit_Services ();
Can someone tell me what I'm doing wrong with this jar file? How do I import this namespace so that I can use the class?
Do I not say:
import com.sabre.*;
Thanks for your help.
Steven Tate

Try
import xmlpowertoolkit.com.sabre.xmlpowertoolkit.*;
OR
import com.sabre.xmlpowertoolkit.*;
I think com.sabre.* will just get you the classes at that "level" ... it doesn't grab the classes in subfolders.
i hope that works.

Can you get the file name of the current executing TSQL script?

Can you get the file name of the current executing TSQL script? I wrote entries to a generic log file and would like to include the script name.

Okay, So What you can do is
1. Read get the version from your database and redirect it to a text file(SQLCMD outout can be directed to text file using -o option or windows redirection operator >)
2. Now you can read this value from the text file either inside a batch file or a powershell script and decide what operations you can do.

In wich jar can i get this class org.apache.batik.dom.util.DOMUtilities

please let me know in which jar file can i get this class and tell me the location for downloading
org.apache.batik.dom.util.DOMUtilities;
import org.w3c.dom.Document;
