Problems with CLASSPATH in a executable jar file

Hi there
I'm having a problem that I don't know how to solve. My generalq uestion is:
"Why isn't my CLASSPATH (java.class.path) forwarded into ar unnable class inside a jar file?"
The situation is:
I have made a runnable jar file containing an ant build.xml file, a jar file containing some patch files, and a class called AntLoader.class. AntLoader are the file that are executed (inserted into the manifest). This works. The class are executed, but it can't find the package needed for starting ant.
ant.jar is in my CLASSPATH, and therefore everything works fine if I'm running AntLoader outside the jar file.
I know that I can use different ClassLoader classes for dynamicly loading of a class, but then I need a path to where ant.jar is located. And then again my system wont be general. The jar file is supposed to be distributed as a system patch to customers. And their location of where ant is installed will not be the same.
So what I'm looking for is a way to pass my CLASSPATH from my environment on to a jar file. Is that possible?
running java -classpath "${CLASSPATH}" -jar cpc.jar doesn't help at all. The java.class.path is still set to cpc.jar when I'm executing the AntLoader class inside cpc.jar.
Can anyone please help me?

've found the solution to the problem. You have to use the -Xbootclasspath/a parameter when running java.
Example on unix:
java -Xbootclasspath/a:${CLASSPATH} -jar test.jar

Add classpath in an executable jar file

an executable jar file contains a manifest file with entry main-class: MyApplicationClass.
if we double click the jar file on Windows OS, main class is loaded.
my question is:
if classes in he jar file use classpaths which are not default, how to add those classpaths into manifest file to tell classes to use those classpaths?
it is similar to command line:
java -classpath c;\mypackage; .......; MyApplicationClass

Thanks, i will try soon.
here is another Q.
if i need to add tools.jar (JDK lib) as classpath in manifest file, it is as following in my PC
d:\install\java\jdk14101\lib\tools.jar.
but my customers install JDK in different path (should be considered as unknown), how to add it as entry Class-path for all customers?

Problems with classpath and accessing a specific file

I'm currently running an application using NetBeans (I know this is the Sun Forum but maybe someone can help). For those who aren't familiar with this IDE, whenever a project is created, a ProjectName folder is also created. Inside that folder are 5 new folders (*build*, dist, nbproject, src and test) as well as 2 new files (*build.xml*, manifest.mf). The dist folder contains the *.jar* file.
Seeing that this is an audio application, I am constantly working with audio files. In the ProjectName folder, I've created a sixth folder (*audiofiles*) were I load and save such audio files. To access a specific audio file, I do the following:
File audioExample = File("audiofiles" + File.separator + "audio.wav");When I run the project from the IDE there doesn't seem to be a problem. However, when I try to run the project by simply double-clicking the *.jar* file in the dist folder, the audio files can't be accessed. In order to be able to access them, I need to change the path:
File audioExample = File("C:\...\ProjectName\audiofiles\audio.wav");This seems to solve the problem temporarily, but if I decide to change to project folder location, I also need to change the path.
QUESTION:
What is the best way to access files so that they are not dependent on where the project folder is located? Do I need to modify the classpath or simply write the path in File(...) in a specific way? If I need to modify the classpath, how can I do so in Netbeans?
Thanks in advance.

DrClap,
Thanks for the reply. To answer your questions:
Naturally that depends on where you DO want to load from. Are the files in the classpath? Are they in the current working directory?
Some other directory where you can ask the user to point to? On a different computer?The audio files are located in a created folder in the IDE project folder. I know you mentioned that I should stop thinking about this as an IDE project but I don't know any other way to think about it. I'm kinda new to Java, and the only way I've learned how everything is structured is through the IDE project structure. I'm realizing that this is probably not the best way to go about as it doesn't allow me to have a good understanding of the Java file structure. What changes do I need to make in the way I view my IDE project to make it more into a deployed version?
I'm also having a hard time understanding the classpath concept. I've been under the impression that the classpath was simply the location of the packages and classes of a specific application. How could I check if the audio files are in the classpath?
Thanks in advance.

Need help with classpath configuration for external jar files

We have coded our own JAAS login module, and it uses classes located in jar files, and these jar files were not created using SAP dev studio, e.g. they were provided by a third party vendor as a set of tools.
So, how do we deploy these jar files so that our SAP JAAS login module can find them ? We found we can run consoleconfig.sh to change the classpath which SAP J2EE engine uses, but we wondered if there was a better way to do this. Of course, if the jar files were created by us, we can include them in the dev studio project and they would be deployed using SDM, and this would not require any changes to classpath using consoleconfig.sh
Thankyou in advance for your help.

I noticed nobody has sent any feedback on this yet, so I wondered if I have posted to the wrong forum ? Any thoughts on this ?
Thanks,
Tim

Newbie's problem with executable jar file

hello
i create an executable jar file and it seems ok except it fails to locate all of my image files.
when i use
java -jar myproject.jar
it fails to display included pictures and files.
however, when i extract this jar file and run, it works fine (displays everything).
do i need to do add some informations about these included file's information into Manifest file?
thank you

thank you for the reply.
i have searched through java, and find "class javax.commerce.cassette.JARCassetteLoader". is this one you referred? i have used file related examples from the java-swing samples.
//post - return the file path
protected static ImageIcon getImageIcon(String path)
java.net.URL imgURL = TestDialog.class.getResource(path);
if (imgURL != null)
return new ImageIcon(imgURL, description);
else
System.out.println("Couldn't find file: " + path);
return null;
then i just use
ImageIcon icon = getImageIcon("images"+File.separator+"simple.gif"); // images\simple.gif
thank you

Problem in loading applet from non executable jar file

hello ,
I am new to jar concept plz help.. I am trying to call an applet from another applet through frame it is working fine but its download time is much more. now i want to store all my images , sound files and class files of other applets in a jar file and want to access these inner applets from this jar file so that it will make only one http connection with the server for this jar file only and can reduce the download time of applet.
Can anyone can give me suggestion plz..
Thanx

You have to download what you have to download. You
probably can't easily share images between 2 separate
Jar files. Unless you can expose them through the
other applet via a method that can be known once you
have the reference to the other applet.Thanx but i think i have to elaborate the problem :
my project structure is just like this ::
on the top is ::
Applet A---> from this applet i am callling Applet B & Applet C in frame
and communication is established between these 3 applets successfully .
now i have made a single non executable jar file which contains images , sound and class files of these applets .
so i am referencing images and sound files in applets through this jar.
but i wanted to load Applet B & C through this jar file only.
How can i do this ??
Thanx .. I hope now the problem is clear

[b]Simple Deploy problem- making an Executable JAR File ...PLEASE HELP [/b]

Hi all,
I Trying to deploy a simple J2SE app by making an Executable JAR File, however I don'r understand how to add a valid value to the Main Class field.
I followed the following description within Jdev, after creating a Deployment Profile:
Deploying an Executable JAR File
You can make your simple archive or J2EE Client Module into an executable JAR file that you can launch with the java command.
To deploy an executable JAR file:
1) Select and right-click the simple archive or client icon in the Navigator to display the context menu.
2) Choose Properties.
3) Click JAR Options in the tree.
4) Select Include Manifest File (META-INF/MANIFEST.MF).
5) In the Main Class field, enter the fully qualified name of the application class that is to be invoked.
7) Click OK.
8) Launch the executable JAR file from the command line:
java -jar myapp.jar
where myapp represents your JAR file name.
Like I said it's in 5) I'm doing something worng
My deploy-file (PlotPrint.deploy) looks the following:

Classpath is not working for executable jar file

I have created executable jar file using following command where manifest file contains Main-Class and Class-Path entries.
jar cvfm app.jar META-INF/* lib/* *.class
So here app.jar contains my external jar's in lib directory
but when I move app.jar to another directory, it's doesn't get my external files.
I'm not getting this problem as these jar's are in app.jar
class-path entry in manifest file:
Class-Path: lib/abc.jar lib/xyz.jar
Pls help me where it is getting fail?
Thanks in advance,
Vikas

Java doesn't handle jars within jars. Your library jars need to be outside of the executable jar as in
dist - main.jar
- lib - lib1.jar
- lib2.jar

Executable Jar files with Oracle drivers and Oracle classes

I have a program which works perfectly that is used to do file
maintenace on an oracle table. Now I am ready to make this into
an executable jar file. I know how to do this, but my problem is
now how do I get the Oracle classes into my jar? I think they
are all in classes12.zip, but just adding classes12.zip into the
jar doesnt work. I still get an error when running the program
that says it can't find oracle.jdbc.drivers.oracledriver.
You can use the jar command to add all classes in a directory,
but this doesnt work either.
Has anyone out there ever done this? Please help if you know how
to do this. How do you put the oracle classes into you
executable jar file?
Wah!!!

Me again. I forgot to mention that I am only using Java. We
don't have Oracle forms or jdeveloper. This is just straight
java. Everything worked until I tried to executable jar creation.

Error trying to run an executable Jar file

Hi,
I know a million people have asked this before. In the past 5 hours I have waded thru a dozen questions-answers-FAQs that were no help. So if anyone is willing to help a stupid person her is my problem:
I developed a java program using the eclipse ide and it runs fine from within that ide.
I packaged it into a Jar file, created a manifest file per the instructions.
But when I double click on the jar file I get the following error from the Java Virtual Machine Loader;
"Could not find main class. Program will exit."
My Manifest file has the following text:
Manifest-Version: 1.0
Class-Path: swt.jar
Main-Class: .graphicalUserInterface.AppStandAlone
<blank line>
the class AppStandAlone has the method "public static void main(String[] args) "
it is in a package called "graphicalUserInterface".
Any help anyone can give me would be greatly appreciated.

Another 3 hours spent trying to run this java application in a Jar file.
I identified that I did not have all class paths specified. So I tried to enter them in the "Class-Path:" line of the manifest file. But, according to the java tutorial, the syntax in a manifest file for classpaths is a space SEPARATING each path name. I have a space IN the path name and java is not understanding the paths correctly. For instance, I have a classpath c:\Progran Files\Java\etc... and java interprets this to be a classpath c:\Progran with Files\Java\etc as the program I want to run.
I tried enclosing the paths in double quotes. Didn't work
I tried enclosing the paths in single quotes. Didn't work
I tried using a semicolon as a separator with double quotes. Didn't work
I tried using a semicolon as a separator with single quotes. Didn't work
I tried using a semicolon as a separator with no quotes. Didn't work
I removed the "Class-Path:" line from the manifest and tried adding -cp param to the java command. Example:
java -cp %classpath% -jar myapp.jar
I tried all the variations above in the -cp param. None of them worked.
The only thing that works is if I move executable jar file to the same directory as the required libraries. Then I specify a "Class-Path:" line with no spaces in the path names. Obviously this is not a permanent solution.
If anyone else has the patience to help me I would really appreciate it.

Can't Execute JAR file deployed from JDev 903

Hi Everyone:
I took the Oracle beginning Java class, and got a copy of JDeveloper 9, and started in on a project. The task was to create a small module that will allow users with no direct SQL access to change their Oracle passwords. The good news is that it runs great from within JDev; it catches exceptions cleanly, it handles multiple databases with no problems. The bad news is that I cannot get it to run from a batch file or command line (client is Windows). I have run 'setvars', I have copied the CLASSPATH from the run window in JDev, all to no avail.
I am trying to deploy the app as an executable jar file. It's not meant to be an applet, because of the security implications.
I would gladly RTFM, but the FM's that I have gloss over the deployment step in Jdev. I figure it's something obvious, but I just cannot figure it out.
Any suggestions? Help a newbie...
Thanks,
Mike

Hi Mike,
I suggest you take a look at the log window of JDev, when you've successfully run your project.
If the log window is not displayed, go to View | Log.
Cut the command line, invoking javaw.exe, and paste it into your favorite editor.
Change javaw.exe into java.exe, save your file as a bat file, go in a DOS console, and run the bat file.
Let me know if it fixes your problem.
Thanks,
- Olivier

Well, normally if your Jar file has a manifest file with the Main-class defined, you wouldn't need to use the -cp switch, in that case
java -jar Sample.jarwould be enough. In fact the -cp flag is ignored when invoking an executable jar; the classpath MUST come from the manifest.This could be a 'cultural difference' in understanding, but it would be more accurate to say the -cp option is ignored if the -jar option is specified. This would mean that the -cp flag is not ignored in this command.
java -cp Sample.jar SampleAnd while I am here, a question for the OP that I am not clear on. The manifest.txt used, does it end with one entirely blank line? (Note that copy/pasting the manifest.txt here will not prove anything, since the forum software will chew up the blank line even if code delimiters are used.) The symptoms of the problem do sound like the JVM is detecting the manifest and successfully reading the main-class attribute, since the stacktrace specifically stated it failed to load Sample.

Cannot make executable jar file for swt application

hi to all!!! i have started learning swt library and it seems nice to me, but i have one problem, i cannot run my application. The problem is that i cannot make executable jar for it.
i'm using ecilpse_3.1.2 and have pluggined the visual editor for swt! yesterday i found one topic where was described the process of making the swt executable jar, i followed the instructions in the topic, but didn't resolve my problem, so if anybody knows how to achieve this , please help!!!!!!
the instructions in the mentioned topic are :
1. Make sure the SWT jar file is included in the Eclipse project build path
a. Download the standalone SWT jar file from eclipse.org even if you already have the ones that come with Eclipse. It is called ?swt.jar? and you will package it with the executable JAR. Make sure it is the same version of SWT that you used to make your program.
b. In Eclipse, import swt.jar via Project Properties::Java Build Path::Libraries::Add External JARs. (Make sure to include the source .zip file). Also make sure to select the swt package in the ?Order and Export? tab.
c. At this point, you should be able to compile and run your SWT application in the Eclipse SDK.
2. Do a standard Eclipse jar file export
a. Right click on the main .java project file and select ?Export??.
b. Choose ?JAR File? from the list.
c. Select the relevant packages and .classpath and .project resource files
d. Make sure ?Export generated class files and resources? is selected and browse to the location where you want the JAR file to be created.
e. Specify ?Generate the manifest file? and don?t seal the JAR or any packages. Choose the class containing the main method as the ?Main class?.
3. Change the manifest file
a. Navigate to the JAR file you created and open it with WinZip.
b. Open the MANIFEST.MF file inside and copy the contents.
c. Create a new file called ?MANIFEST.MF? and paste in the contents of the old manifest file.
d. Add the line ?Class-Path: <swt jar file path>?. For simplicity, you can just keep a copy of the swt.jar file in the same folder as the executable jar, in which case, the line is ?Class-Path: swt.jar?. Make sure there is a carriage return after the last line in the manifest file, or that line will not be parsed.
4. Replace the manifest file
a. Make sure the manifest file and the executable jar are in the same folder.
b. Open the command prompt and navigate to the containing folder.
c. Enter the command ?jar umf MANIFEST.MF <executable jar name>? to update the manifest file with the class path information.
5. Package the JAR with SWT files
a. Put the updated executable JAR file, swt.jar, and the associate DLL in the same folder. The DLL can be pulled out of swt.jar and should have a name like ?swt-win32-####.dll? on Windows.
b. The JAR file should now successfully execute. On Windows, you can usually just double click the JAR file in explorer and it will open. If that does not work, the command ?java ?jar <executable jar name>? on the command line has the same effect.
but a few steps aren't exact for me , for example : first, which jar i have to include in build path : downloaded or from plugins folder, second
i have to incude source.zip too??? but it is only in downloaded zip file which includes both swt.jar and src.zip, and finally can anyone clarify next :
"5. Package the JAR with SWT files
a. Put the updated executable JAR file, swt.jar, and the associate DLL in the same folder. The DLL can be pulled out of swt.jar and should have a name like ?swt-win32-####.dll? on Windows."
what does this mean, put these in folder or make jar from them????

wolve634 wrote:
but a few steps aren't exact for me , for example : first, which jar i have to include in build path : downloaded or from plugins folder, secondTry it both ways. If neither works, then ask again. In a suitable forum, though. An Eclipse forum or an SWT forum or something related to where you got those instructions would make a lot more sense than asking here.
i have to incude source.zip too???No, of course you don't have to distribute the source code.

Creating an executable jar-file including a custom package

I am trying to learn how to create executable jar-files. I have managed this with a single class. However having a class which is an extention of another class which in turn belongs to custom package, I can't make it work.Running the program normally is not a problem. I don't think the problem is the actual code, but I will include it here anyway. I create the jar-file using:
jar -cmf Direkt2b.txt Direkt2b.jar *.class
where Direkt2b.txt is just:
Main-Class: Diriekt2b
Only the main class-file is included this way. Copying the other file to the same directory before creation doesn't help either. There is no error messages, the jar-file just refuses to run no matter what.
The main-class:
import java.awt.*;
import extra.*;
class Direkt2b extends ExtendedFrame {
     Font f;
     Direkt2b() {
          f = new Font("SansSerif", Font.BOLD, 24);
          setBackground(Color.yellow);
          setSize(400,150);
     public void paint(Graphics g) {
          g.setFont(f);
          g.setColor(Color.blue);
          g.drawString("V?lkommen till Java Direkt", 45, 100);
     public static void main (String[] arg) {
          Direkt2b d2 = new Direkt2b();
          d2.setVisible(true);
The help-class:
package extra;
import java.awt.*;
import java.awt.event.*;
public class ExtendedFrame extends Frame {
     private static boolean first = true;
     private boolean isFirst = first;
     public ExtendedFrame() {
          addWindowListener(theListener);
          first=false;
     WindowAdapter theListener = new WindowAdapter () {
          public void windowClosing(WindowEvent e) {
          dispose();
          if (isFirst)
               System.exit(0);
}

My problem wasn't really getting more than one class in a jar-file,
but rather that my jar-file with multiple classes wouldn't execute.
Reading the original post I realized that maybe I was unclear about that.
However I have solved the problem now so for anybody reading this
thread in the future I will tell you how.
The general setting is this: You have a bunch of self-made help-classes
organized in some classdirectory somewhere in the filesystem. You use these
in your programming from time to time. You have set a classpath-varible
in your OS such that Java could find your help-classes.
Now you want to create executable jar-files so that you could publish your work.
My problem was that while I added all needed classes in a jar-file, the main-class
couldn't find the others because they were referenced incorrectly. The solution I
came up with may not be elegant, but it works. I copied the main-class and all directories
(only one in my case) just as they appear in the classpath-directory, to the same temporary
directory. Then I created the jar-file from there, using: jar -cmfv Direkt2b.txt Direkt2b.jar Direkt2b.class extra/*.class
I suspected that incorrect referencing was the problem and I tried several variations on the theme above
before giving up and writing the first post. Part the problem was that I didn't get any error messages,
just an annoying error-sound double-clicking the jar-file. I learned later that you could run jar-files from
the command -prompt using: java -jar myjarfile.jar. This way you get a more useful response.
I guess there is a way to include the classpath instead somehow, but I will use my method for now.
I hope this was helpful to somebody.
