Jar file with JRE and lib's

I'd like to create a jar file that also contains the JRE that I want to use as well as some libraries I'm using. Is that possible?
I have created in the past a batch file that points to an specific JRE that I package with my classes in a directory. But this time I'd like to package it in the jar file as well.
Thanks!

How do you create a jar file with txt and classes?

Hey, I'm trying to create code to create a jar file with a text file, but I can't figure out how to add the text file. Here is what I have so far:
try {
            // Name of jar file to write
            String archiveFile = "test.jar";
            Manifest jman = new Manifest();
            try {
                // Create a manifest from a file
                //InputStream fis = new FileInputStream("manifestfile");
                //Manifest manifest = new Manifest(fis);
                // Construct a string version of a manifest
                StringBuffer sbuf = new StringBuffer();
                sbuf.append("Manifest-Version: 1.0\n");
                sbuf.append("Ant-Version: Apache Ant 1.7.1\n");
                sbuf.append("Created-By: 1.5.0_19-137 (Apple Inc.)\n");
                sbuf.append("Main-Class: Main\n");
                sbuf.append("Class-Path: lib/swing-layout-1.0.3.jar\n");
                sbuf.append("X-COMMENT: Main-Class will be added automatically by build\n");
                // Convert the string to a input stream
                InputStream is = new ByteArrayInputStream(sbuf.toString().getBytes("UTF-8"));
                // Create the manifest
                jman = new Manifest(is);
            } catch (IOException e) {
            FileOutputStream stream = new FileOutputStream(archiveFile, true);// archive file is jar file name
            JarOutputStream out = new JarOutputStream(stream, jman);
            out.putNextEntry(new JarEntry("test.txt"));
            out.closeEntry();
            out.close();
        } catch (Exception ex) {
        }It creates the .jar file with the correct manifest but I can't get it to write the test.txt or anything else into the jar file.

            out.putNextEntry(new JarEntry("test.txt"));
            out.write("Hi".getBytes());
            out.flush();
            out.closeEntry();
            out.close();
        } catch (Exception ex) {
            JOptionPane.showMessageDialog(this,ex.toString(),"BUG!",JOptionPane.INFORMATION_MESSAGE);
        }It creates the jar file with the txt file inside it, but I can't write "Hi" inside of the text file. Any ideas?

Installing a JAR file with NAL

This is in reference to my previous message about trying to use NAL to get
to a URL with System Rights...
In addition to having to install Java to use our new webpage, there is a jar
file that has to get pushed out, too.
It's not available as an executable, but, is there anyway to push out a jar
file with NAL? Does it need to be run, or, just copied somewhere, and, if
so...where?
Thanks!

We have an AGFA Imaging system that puts digitized x-rays, CAT-scans, etc.,
up on a webserver, so that docs all over our hospital can pull them up and
look at them.
The previous system HAD to use the MSJVM, but, last Saturday they upgraded
the system (not really telling us the requirements ahead of time...<G>), and
it had to use the Sun JRE. Sooo....I had to setup an AppObj last Sunday to
push out Java to all workstations, so went to Java.com and downloaded the
latest version, 1.5.x
Well...of course they had to use a certain version, 1.4.1_01, and, it
wouldn't work with 1.5.x at all, so, I pushed that out, then it turned out
that they use a product from Germany (AGFA, you know) named JacoZoom, and a
jar file is asked to be run by the users when they first login to the
website, and, of course...you have to be an Administrator.
Our VA Security Managers like to over-protect us, so, the German site
hosting JacoZoom is blocked, and, rather than drive home and download what I
needed, I thought it would be easier just to push out the URL with System
Rights temporarily (you understand that by this time, Monday afternoon, all
our 400 doctors were up in arms because they couldn't view any images), and
then the trying to push the URL just didn't work.
Sooo...I drove home and got the JacoZoom product (had to buy it), which is a
large executable containing several JAR files when exploded, one of which
was the one that was being pushed out. Running the executable didn't do the
trick (not sure why), and the JAR wouldn't run, even manually, but, I
FINALLY found an email from another tech going through the same hassle, and,
all he did was push a different JAR file to the \lib\ext folder in the JRE
1.4.1_01 folder...and it worked.
I did that, and, it worked, and deployed it all over the building.
Welcome to my world--and, I'm not complaining, because with SMS (which we
have to run, but don't use), I'd still be configuring the deployment
package.
Thanks.

Re: Recognizing JAR files in WEB-INF/lib

Hi Steven,
Sorry for the late response, next time you can do this in a more simple way
by launching Properties window (right click on project) and select Java
Build Path, click on Libraries tab.
Thanks

Updated JAR files in j2ee/home/lib

We are developing and deploying j2ee applications to a 9.0.2.3 9iAS server. We have a framework.jar file that we have a number of applications in two OC4J instances (home and portal) that need to use this jar file. As a result, we place the jar file in the j2ee/home/lib directory since this could be seen by all applications. My question comes in when we try and update this jar file. We seem to experience problems when moving a new framework.jar file into the directory. We mainly notice this issue in our EM Website. We begin to get the following error in the EM Website after we move an updated jar file into the directory:
Servlet error: Renderer failed: java.lang.InternalError: jzentry == 0
I've seen this error before and it seems to link back to a problem with jar files. If I remove the new jar file the error disappears. We are eventually able to get the jar file in, but only after restarting the whole mid-tier. Is this normal? Should we have to restart the server everytime we update the jar file? If so, what would be the best way to implement the new jar files? Stop mid-tier, move new file in and restart??
Would you recommend a different location for this jar file?? Our biggest concern is that we only want to deploy this jar file one time and have all applications that need it find it. Thanks in advance for any input you might have.
Beth

Libraries loaded from the j2ee/home/lib directory are opened and loaded at the J2EE container level. So they are accessed from the very start of the server, to the point where it is stopped.
Therefore if you modify a class library which has already been loaded, you may run into file locking related issues (which will be OS dependent, Windows for example probably won't even let you overwrite the file) so that is what you are likely to be seeing.
JAR files loaded at the J2EE container level aren't really suitable for dynamic updating -- the classes can be referenced in a multitude of other classloaders.
As you have seen, replacing a J2EE container level class file, then a restart will be required along the lines of what you have written.
Stop mid-tier, move new file in and restart?? cheers

How to run jar files with arguments?

Hi everybody,
Is it possible to run a jar file with arguments passed to its MAIN class?
If yes can you help me on how to do it?
Thanx

I am in complete agreement with FahleE. I'll refine it a bit.
On my machine (running RedHatLinux8.0) you can run the demos like this.
1. open a console window
2. go to the directory where the demo you wish to run, say, demo.jar, is located
for instance for the SwingSet2-demo
cd /usr/lib/java/demo/jfc/SwingSet2
3. run the jar file
java -jar demo.jar
In order to run it windows style, ie, launching by double clicking, save these lines in a file called
LaunchJar.sh
cd /usr/lib/java/demo/jfc/SwingSet2
java -jar demo.jar
where demo.jar is the jar file you want to run.
Right click on the LaunchJar.sh and go to the 'Properties' tab. Check the 'Execute' permissions for Owner/groups/others. You can also do the same thing by chmod command.
Now double-click on the LaunchJar.sh file: your application should be launched.
Palash.
Please Note: It is important to set the path variable to your JAVA_HOME directory....
Otherwise, instead of
java -jar demo.jar, you will need to use the full path to your JAVA_HOME/bin directory like:
JAVA_HOME/bin /java -jar demo.jar.
Where JAVA_HOME is the directory where you have installed java. Typically it is usr/java or usr/local/java

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

ServiceBus java callout - how to pack the JAR file with libraries?

Hello
I want to use a Java Callout from a Service Bus flow.
What is the correct way to pack the JAR file with its nessecary libraries?
I tried different methods to pack my JAR, but yet, as though the Java runs perfectly from the Workshop (Eclipse) , when I am trying to use the exported Jar on the ServiceBus flow, it fails with an ClassNotFoundException.
I would really appreciate your advice here.
Thanks
Koby

Well.. Looking inside my exported JAR file, I got all of the files there inside, including the jar file containing the library.
What I'm trying to do is run a simple java program that connect through SSH and therefore use an SSH library.
On the workshop I got it as an imported library JAR. And it works perfectly there.
Any idea?

Packaging jar file with classes

Hi experts,
I want to clarify a problem in relation with packaging .class files in jar file making
it jar executable.I was able to achieve this when number of classes are limited and confined to only a single program.However recently i developed a software
which is very much like SQL*Plus and retriee my company database using screen buffer management and i have handled almost all the issues.
But so long to execute this program i am typing
java <Program name>.It is using Oracle as backend.
I tried to package Oracle driver files in jar using
jar -cmf manifest.mf sqlpad.jar *.class Oracle\
where Oracle directory contains all the class files in separate folders like
Oracle\javax etc
I get a jar file with hefty MBs size.It is executable too.But when i try to connect to
database, i get message Oracle driver class is not found.
In what way should i package it as jar file ?

I wouldn't add the drivers to the JAR itself. Instead, I'd suggest one of the following:
1.) Add classpath entries into your manifest file pointing to the drivers' JARs
2.) Create a batch file for starting that contains a call to "java -classpath ..."
3.) Add some way to your app to configure additional classpaths at runtime and use a URLClasssLoader (and a wrapper class for the driver for registering with the DriverManager) that loads the driver's class

Partial redeployment of a static jar file with weblogic.Deployer

Hello,
We are working on an application serving jar files to customers, via Java Web Start, hence that are considered from our point of view as static files, like our HTML and Javascript pages.
Moreover, we have one jar that changes regularly, so every time it's loaded on the server we need to do a partial redeployment of this jar file, as documented here: http://docs.oracle.com/cd/E13222_01/wls/docs103/deployment/redeploy.html#wp1025739
However, it does not work, as I believe WebLogic doesn't consider my jar file as a static file.
C:\>java -cp weblogic.jar weblogic.Deployer -adminurl http://mymachine:7001 -user weblogic -password mystrongpassword -name myapp -redeploy launcher/downloadme.jar

1.) The resource does not exist.
or
2) The resource cannot be changed dynamically.
Please ensure the resource uri is correct, and redeploy the entire application for this change to take effect.
As a side note, if I rename downloadme.jar to downloadme.jar.*html*, then WebLogic agrees to redeploy it!
Is there any way to force the static redeployment of my jar file?
Thanks and regards,
Julien

Hi,
The feature you are trying to use works only when web application is deployed in exploded format. Is your app deployed in exploded format?
Also jars are never considered static, so I doubt this will work here.
As an alternative you can go for Oracle Weblogic Production redployment feature. Refer to - http://middlewaresupport.wordpress.com/2013/03/21/production-redeployment-feature-in-weblogic/
Thanks,

JAR file with definition of bpelc task

Hello:
I checked all the JAR files under c:\orapel\lib and
did not find the definition of the 'bpelc' task, so
I can't invoke 'ant'. Can anyone tell me the name
and location of the JAR file that contains the
definition of this task? Thanks...
Regards,
Oswald

Ah, I just noticed that $BPEL_HOME\bin\obant.bat
find everything that's needed....

Can't run .jar file with JavaSE

Hello.
I'm trying to run a .jar file with JavaSE Binary, just like I did with Windows. I Ctrl+Rclick and pick "Open with..." and there is no such option. I've been searching the whole day for a solution, I kept getting "Open Java Preferences... put on top of the list" and things like that. There is no "Java Preferences" in the Utilities folder, and nothing related to my problem in "Java Control Panel" in System Preferences. Yes, I have Java 7. I just need to run this file with Java. How?
Thanks in advance.

Max. allowed size of .jar file is 1MB.

How to run jar file with classpath?

Hi, all,
I have some package in my project, with which I have a java help jar file as classpath, when I run my project, I need the jh.jar file in directory /jar/jh.jar.
Now, I bundled all my class packages into a jar file, my.jar, together with the /jar directory. When i run my jar file with command:
java -jar my.jar
It tells me couldn't find javahelp class.
What shall I do? How can I create my jar file with the jh.jar?
Thanks in advance.

Thanks, hjembaek,
But it doesn't work for me. I am running in windows, it still generate the error:
Exception in thread "main" java.lang.NoClassDefFoundError: javax/help/HelpSet
at own.gui.OwnMenuToolBar.getOwnHelpBroker(OwnMenuToolBar.java:560)
at own.gui.OwnMenuToolBar.addHelpMenu(OwnMenuToolBar.java:327)

at own.gui.OWNDPTool.<init>(OWNDPTool.java:39)
at own.gui.OWNDPTool.main(OWNDPTool.java:100)
Here is my command to generate the jar file:
jar cfm Own.jar temp.txt help own log others
temp.txt is the file including the main class and class path information
I have help folder, log folder and own package, others is directory that has the jar file(others/jh.jar)
