How to run 1 or more main classes in a jar?

Hi there,
I have 2 or more main classes in a java project. How do I create more than one application entry point in my MANIFEST.INF? I create my jar file from my java project using Eclipse, and it asked me to "Select the class of the application entry point". I was only able to select one main class.
I noticed the MANIFEST.INF file that eclipse generated looks like:
Manifest-Version: 1.0
Main-Class: Automobile
When I tried to run my other classes not specify in the MANIFEST.INF it failed and only look for the Automobile class:
java -jar /tmp/Auto.jar TestMe

Your app. can have as many entry points as you like, as atmguy demonstrated. But you can only specify one in the manifest,which - if you think about it - makes perfect sense. How is the machine to determine - from you clicking on the jar - which entry point you meant to invoke?

How to Invoke a main class in a jar file from my project

Hi
I am a new user of the Sun Java Studio enterprise. I would like to know how i can invoke a main method in a jar file associated to the project.
regards
Nisanth

Could you please clarify: do you want to run your project or a project from an independent jar?
In the first case just select Run Project from the project context menu or select a class with main method and click Run File in the class context menu.
Regarding the second case:
- I don't think there is such a feature in the IDE (running third party jars is not an IDE function). Could you explain why you need this?

Could not find the main class (with every jar)

This isn't a developer question. I get the error Could not find the main class with every jar I try to open (for example the jar downloaded from https://gjar.dev.java.net/ gives the same problems - and I don't think there is something wrong with that JAR). It isn't a problem with the jar or MANIFEST because the same jar works fine on my laptop. So there is something wrong with my JRE installation, but what?
I tried to remove and reinstall the JRE 6 Update 18 but that didn't work. When I run the JAR with command line java -jar "file.jar" it works fine, but if I dubbelclick on it I get the error message (and it's irritating me).
I'm a bit desperate so I hope that someone here can help me ;)
Thanks in advanced

Don't know how to make my main class import a jar file

OK, the title doesn't make much sense but here are my create-jar.bat and manifest files:
create-jar.bat:
jar cvmf manifest.txt dassimul-admin.jar player/ admin/ com/ connector/ common/ *.class
manifest.txt:
Main-Class: admin.DASAdmin
the problem is that in connector/ folder there is the jdbc mysql connector driver (.jar file).
in Eclipse I can add this jar to the Java Build Path, so the program runs.
When I double-click the dassimul-admin.jar file, I get a Class Not Found Exception
C:\MYWORK\dassimul>java -jar dassimul-admin.jar
FATAL ERROR WHILE LOADING SQL DRIVER: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
I think that the problem lies in the fact that admin.DASAdmin can't see and import the jar file in connector/ folder... am I right?

It looks like you are putting the mysql jar file inside the dassimul jar. That won't work unless you write custom code. You should use the Class-Path attribute of the manifest to define a relative path(s) to the other jar(s) that you need to use.

How to manage over 200 main classes effectively?

Where can I found some experience about a big System?
What's a main class looks alike?
I got a GUI--subGui--sub-subGUI----...
and configuration--subconfiguration--subsubconfiguraiton...
and others.
How do I connect them together?

The first thing to do is look at whether or not you actually need the 200+ classes ? Don't worry of the answer is yes. See if you cut down on the number of classes - there may already be standard classes available.
That should leave you a smaller number of classes. The short answer to your questions is packages. Group the classes into several chunks of logical component or layers. There should be commonalities between the different views and configurations which lend towards a logical partitioning.
You may want to look at the Struts architecture for guides towards a cohesive web-tier design. Although targeted towards the JSP-Servlet technologies, the Model-View-Controller paradigm applies to the your GUI app.

How to run the imported java class in form

Help!!!!!
Pls help me to run the imported java class in forms.
Package is created in forms while imported one class called
singlexml.class and that package has one procedure and one
function.
I just wanted to run that class.I mean the new package.
Thanks

Hi,
It is because the converter works on byte code and it only supports a subset of the Java language (see the JC specifications). It is kind of like compiling you code on Java 6 and trying to run it on Java 5. The JCDK outlines the required compiler version.

JRE doesn't find the main class inside a JAR archive file

Hello everybody,
I've written a small application in Java, using NetBeans. Running my application inside NetBeans works fine, but I can't run it from the console or by double clicking the jar file.
Running it from the console I get the following error message:
java -jar TestApplication.jar
Exception in thread "main" java.lang.NoClassDefFoundError: tst.Benchmark
   at gnu.java.lang.MainThread.run(libgcj.so.81)

   at java.lang.ClassLoader.loadClass(libgcj.so.81)
   at gnu.java.lang.MainThread.run(libgcj.so.81)I know that these errors often come when the class path is not set in the right way, and using a single java file, you can fix this by passing the parameter "-cp ."
I tried this with the jar file but it does not work and using "-cp TestApplication.jar tst/Benchmark" didn't work either.
Inside the jar file I have the META-INF Folder and a "tst" Folder which contains all my class files. And I've set tst.Benchmark as the main class, this also stands in the manifest file correctly.
Do you have any ideas what could be wrong?
Greetings JavanianGuy

This line
at gnu.java.lang.MainThread.run(libgcj.so.81)says that you're using GNU's Java, not Sun's Java. They are not the same. GNU Java is incomplete.
You'll need to ask this question at the GNU Java site.
Recommendation: Use Sun's Java

Could not find Main Class while executing JAR

Hello all,
I am having a simple Jar file that contains one java class that merely displays a window. I am using NetBeans IDE to create the JAR file. When i execute this JAR file by double clicking on the file, it works fine on the machine. However, if i try to execute this same file on any other windows computer, it gives an error "Could not find the main class. Program will exit."
In other words, the JAR file is only working on the computer that has NetBeans and JDK installed on. Not on any other machine. Although the other machines have the JAVA Virtual Machine installed.
I would appreciated any help on this topic.

I had the same problem (i.e. Message-Box with "Could not find the main class. Program will exit.")
After insuring that the manifest contained a Main-Class: argument and that the argument pointed to the right class, I started the jar via java -jar myjar.jar and read the stacktrace, which is much better than the popup-window.
In my case the error was, that the Main-Class could not be loaded due to another referenced class, which was not on the classpath. (i.e. it was not in the same jar-File and the manifest didn't include a Class-Path: argument.)
After adding the correct Class-Path: argument in the manifest, the problem went away.
I now have the following setup:
myjar.jar and somethirdparty.jar in the same directory.
myjar.jar contains a manifest which includes the lines
Class-Path: somethirdparty.jar
Main-Class: my.package.and.MainClassafter the normal Manifest-header.

How to run an external TimeDate class

How to run jsp using javabean class in tomcat

hello all,
i have bean class placed in classes folder of tomcat and placed jsp and html in root directory. i am not able to run it , if i have do any setting in web.xml, pls let me know from u

No XML required, but you must put the class into a package.
Packages are folders with some files that identify whats in them, so you will end up with something like
yourWebbApp/classes/yourPackage/yourClass

How to run CS6 more effectively

I made the jump from FCP7 to the Creative Suite for obvious reasons and I am in general happy with my transition except for the fact that while working with Premiere and After Effects together with RED 4K footage, my computer begins to slow down and heat up significantly. It is so bad that I don't feel I am wokring efficiently.
Here are the specs for my 2011 MacBookPro
OSX 10.8.3
processor 2.3 GHz i7
memory 8GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 512 MB
I am more than willing to buy a new computer that can keep up with my editing demands (if that is the issue) but I want to make sure that I make the right purchase as I hear all kinds of different opinions on this matter:
"Buy a PC."
"Your graphics card is all that matters"
ETC....
Any help would be greatly appreciated.
