Jar-files with vm-arguments

Hi,
If I run the junit-tests in eclipse then there are no problems. When I run in jar-files format then it need the vm-arguments(Exception:Arguments not set). How can I pass arguments the my jar-files?
Thank you.

Hi everybody,
I happy, that I'm not the only one suffering from this limitation. Right now I'm writing a Java application which will be used not only by persons who have Java experience. I guess most of them wouldn't even know how else to start it than double-clicking on the jar-file. And in my opinion, that's perfectly alright! When starting an native executable, you also don't think about defining a maximum heap size and even non-developers can easily use these applications. But I don't what to start if native applications are better or not. I really love Java and I don't want to miss it, that's for sure.
But I don't understand, why on the one hand Java tries to "sell itself" as a real alternative to native applications and one the see the intention to let Java applications more and more "feel" like them (e.g. with introduction of features like TrayBar support or making it easy to open/edit/... files with any application assigned to that file type), but on the other hand there is no official way to easily setup the environment to start these Java apps. I mean, you can use Applets or the WebStart facility for deployment, but that can't be the right way! I can think about so many applications which I would really like to have as a real offline tool. What is, if the PCs I want to use my app on don't have an internet connection?
Ok, but to make a long story short, I'm really looking for any way to make it easy for the users of my application to "just use it" rather then telling them when how to increase the maximum heap size or which script they have to use to run it. And the only way I see right now is the idea of using a wrapper just for starting a new VM with additional parameters. Even this is a bad hack in my opinion, but I'll try if this is useful for me.
Anyway, I hope that maybe someone already found a better solution cause I can't believe that this problem is really uncommon.
If I find a better solution I'll let you know.

Black Widow

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?
Here's the complete error I get:

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

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.

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 can i run this bat file with 2 string arguments?

Hi,
thanks thats good and helpfully
so this code works:
String loc1 = "\"/a\"";
String loc2 = "\"//a\"";
String path = System.getenv("MuSatSolver");
String[] cmdarray = {"cmd.exe","/C",path+"XPathOverlap.bat", loc1, loc2};
Process p = Runtime.getRuntime().exec(cmdarray);
p.waitFor();
System.out.println("Exit Value: "+p.exitValue());
InputStream cmdErr = p.getErrorStream();
InputStreamReader isrErr = new InputStreamReader(cmdErr);
BufferedReader brErr = new BufferedReader(isrErr);
String line2 = null;
while((line2=brErr.readLine())!=null){
     System.out.println("Error: "+line2);
but now i have another problem, this is the output:
Exit Value: 0
Error: java.lang.NoClassDefFoundError: fr/inrialpes/wam/treelogic/_xml/XPathOverlap
Error: Exception in thread "main" The Exit value is 0, so the process terminates normally.
I have tested this bat file in cmd and there it works correctly.
Why do i get this error message?

Create a complete jar file with jscreator

Please provide all details for creating a jar file with jscreator for this 77 year old puzzle creator

Hi,
I would suggest switching to NetBeans IDE. It allows for the following:
- Ability to run with latest JDK release
- Enabled with the latest Java technologies
- Support for a greater number of application servers
The following will help with migration (if you already have a project setup in Creator)

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.

Signing JAR file with DSA algorithm

Hi everybody,
I need to sign my JAR file with DSA algorithm.
Can anybody explain how to generate certificate for this and how to sign using DSA algorithm.
Thanks.

Well J2SE 1.x supports ZipOutputStream (jar's are zips with a META-INF/MANIFEST.MF file) and www.bouncycastle.org has API's for signing etc.
So in theory you could take a directory or an existing jar and make a jar and sign it.
The only question is the format on how to sign them properly. I wouldn't be suprised if someone already wrote an API for this format. For example BouncyCastle supports S/MIME and PGP, but I don't know what is the format for jars.
