How to run Java App in Jar file

I can run Java App jar-ed into 1 jar file with java -jar App.jar
But sometimes I need to jar only the app and bind the other classes from different place. So I tried to use:
java -classpath c:\utils.jar -jar App2.jar
where classes in App2.jar link to utils.jar. I just can't make it work. Any idea/help.
thanks

hi HasanOen
u need to edit the manifest file in yr JAR file u can do this by using the following cammand or by making the batch file but make sure all the files are in same folder.
first of all u need to make a text file like below
/////////// first file name: "THIS.txt" /////////
Manifest-Version: 1.0
Created-By: java // whatever here
Main-Class: PUT YOUR MAIN CLASS NAME HERE (like MAIN)
//////////////////// BATCH FILE "RUN.bat" //////////////
jar cmf This.txt App2.jar MANIFEST.mf com
com is the folder where your all the class file are.
now double click the run.bat file. this will edit yr manifest file.
hope this should work for u
Note : Make sure yr jar file, txt file, bat file, and yr classes folder is in the same folder(I mean at same level)
regards
Satinderjit

Images not getting Loaded while running Java Application through jar file

Hello Friends,
I have a problem while starting my application.I have written my application using pure java.There is no JSP or anything just pure swings.Mine is a standalone appplication.So i used to run it using a batch file.And when i used to start my application it used to not show me the images.so what i did was i mentioned the starting directory in the properties of the batch file (ie in the start in column field).But that was when i was using weblogic server.And i have lot of people working on the same application.so i used ZAC publisher in weblogic and along with that i used to publish the batch file also.so the users dint have any problem.But now what is my problem is i m trying to use JAVA Webstart instead of weblogic ZAC.Now in webstart what happens is that i have to run the appliaction thru jar file.so where do i mention the class path so that the images get loaded.As of now the imaes are not getting loaded.i feel this is a class path problem.but where do i mention it that is my problem.It would be really helpfule if someone could help me out.
thanx and regards,

How to export desktop app into jar file??

Hello,
I have a desktop application needing some jar libraries.
I've exported my application using eclipse exporting wizard, so I've achieved
an app.jar with a simple Manifest.mf (only indicating Main-Class)
I've modified the manifest.mf to include all the jar libraries in the Class-Path.
The manifest.mf looks like this:
Manifest-Version: 1.0
Class-Path: lib/commons-collections-3.1.jar lib/commons-digester-1.7.jar Main-Class: com.pack2.pack2.MainClasse
When I try to execute the application with the command line:
java -jar app.jar
The next exception is thrown:
Exception in thread "main" java.lang.NoClassDefFoundError: pack1/class1
at java.lang.ClassLoader.defineClass0(Native Method)

Can anybody help me please?
Thanks in advance!

I've alredy found the solution:
Class-Path: . ./lib/lib1.jar ./lib/lib2.jar
The clue is both on Class-Path attribute sintax and the TWO returns after the last manifest line.
Hope helps others!

How to run .java file in windows ?

How to run .java file in windows without installing any program? Thx!

First, U must make sure that there is JDK on your computer
Then, set the envionment variables which the os can find your compiler and interpreter: javac java
after those, you must complie your .java file to .class file, then you can excute it by java, for example " java helloworld"

How to create and use library JAR files with command-line tools?

Development Tools -> General Questions:
I am trying to figure out how to put utility classes into JAR files and then compile and run applications against those JAR files using the command-line javac, jar, and java tools. I am using jdk1.7.0_17 on Debian GNU/Linux 6.0.7.
I have posted a simple example with one utility class, one console application class, and a Makefile:
http://holgerdanske.com/users/dpchrist/java/examples/jar-20130520-2134.tar.gz
Here is a console session:
2013-05-20 21:39:01 dpchrist@desktop ~/sandbox/java/jar
$ cat src/com/example/util/Hello.java
package com.example.util;
public class Hello {
    public static void hello(String arg) {
     System.out.println("hello, " + arg);
2013-05-20 21:39:12 dpchrist@desktop ~/sandbox/java/jar
$ cat src/com/example/hello/HelloConsole.java
package com.example.hello;
import static com.example.util.Hello.hello;
public class HelloConsole {
    public static void main(String [] args) {
     hello("world!");
2013-05-20 21:39:21 dpchrist@desktop ~/sandbox/java/jar
$ make
rm -f hello
find . -name '*.class' -delete
javac src/com/example/util/Hello.java
javac -cp src src/com/example/hello/HelloConsole.java
echo "java -cp src com.example.hello.HelloConsole" > hello
chmod +x hello
2013-05-20 21:39:28 dpchrist@desktop ~/sandbox/java/jar
$ ./hello
hello, world!I believe I am looking for:
1. Command-line invocation of "jar" to put the utility class bytecode file (Hello.class) into a JAR?
2. Command-line invocation of "javac" to compile the application (HelloConsole.java) against the JAR file?
3. Command-line invocation of "java" to run the application (HelloConsole.class) against the JAR file?
I already know how t compile the utility class file.
Any suggestions?
TIA,
David

I finally figured it out:
1. All name spaces must match -- identifiers, packages, file system, JAR contents, etc..
2. Tools must be invoked from specific working directories with specific option arguments, all according to the project name space.
My key discovery was that if the code says
import com.example.util.Hello;then the JAR must contain
com/example/util/Hello.classand I must invoke the compiler and interpreter with an -classpath argument that is the full path to the JAR file
-classpath ext/com/example/util.jarThe code is here:
http://holgerdanske.com/users/dpchrist/java/examples/jar-20130525-1301.tar.gz
Here is a console session that demonstrates building and running the code two ways:
1. Compiling the utility class into bytecode, compiling the application class against the utility bytecode, and running the application bytecode against the utility bytecode.
2. Putting the (previously compiled) utility bytecode into a JAR and running the application bytecode against the JAR. (Note that recompiling the application against the JAR was unnecessary.)
(If you don't know Make, understand that the working directory is reset to the initial working directory prior to each and every command issued by Make):

How can I get a single jar file with NetBeans?

How can I get a single jar file with NetBeans?
When I create the project I get these files:
dist/lib/libreria1.jar
dist/lib/libreria2.jar
dist/software.jar
The libraries that have been imported to create the project are in separate folders:
libreria1/libreria1.jar
libreria2/libreria2.jar
libreria1, libreria2, dist folders are all located inside the project folder.
I added the following code to the build.xml:
<target name="-post-jar">
<jar jarfile="dist/software.jar">
<zipfileset src="${dist.jar}" excludes="META-INF/*" />
<zipfileset src="dist/lib/libreria1.jar" excludes="META-INF/*" />
<zipfileset src="dist/lib/libreria2.jar" excludes="META-INF/*" />
<manifest>
<attribute name="Main-Class" value="pacco.classeprincipale"/>
</manifest>
</jar>
</target>
Of course there is also the project folder:
src/pacco/classeprincipale.form
src/pacco/classeprincipale.java
Can you tell me what is wrong? The error message I get is as follows:
C:...\build.xml:75: Problem creating jar: archive is not a ZIP archive BUILD FAILED (total time: 2 seconds)

This is not a NetBeans forum, it is a JDeveloper forum. You might want to try http://forums.netbeans.org/. I also saw your other question - try looking in the New to Java forum: New To Java

What is needed as a minimum to run Java apps?

Hello,
I'm running Windows 2000 Pro on a home computer and want to conserve disk space. There seem to be a lot of duplicate files in Java directories on my system. I only want to be able to run Java apps - no development or deployment. What is the minimum installation required to just run apps?
I currently have J2SE Runtime Environment installed.
Thanks in advance,
Kudzuken

I could get all technical and fancy on you, tell you about jre's that can run on palm pilots and such, but nevermind that stuff.
The answer is that the java 2 runtime environment is all you need
Be careful about moving and deleting files tho

How do I deploy an external JAR file

Hello,
How do I deploy an external JAR file?
I am grateful for every hint.

Hi Manuel,
If you read my blog mentioned in the beginning of the thread, you will note that such solution is not supported in our engine due to number of reasons.
Please, read the blog and use application library shared among these two applications. You will achieve the same effect. Please note that the using application will need run and deploy-time dependencies to the shared library.
You should not add files to any of the folders manually or manipulate engine's classpath in such situations.
Best Regards,
Georgi

How to run java program from website?

Hello
I'd like to know how to run java program from my web page.
I'd like to push some button in this web page so java program that would be on my server
would pop-up. Can it be done automaticaly upon running this web site? (without any buttons - I just enter website and program pops up).
Cheers

I rather thought about RMI. But I could try servlets. So how it would look like?.
I would make http request in browser (enter address) and program would show up in its window?. And I would not have to change anything in my program?. This program would run then on both boxes?. One remotely and one not?.
But I would have to learn some basics, I've never worked with servlets. Could you suggest some good sites about it?. With ready examples so I could tweak them to my purpose.
