Jar files exporting

Hi all,
I have a jar file that works along with some C plus plus dll s.
I need to package the jar in such a way that it should have the necessary files
for the jar to open and there is no need for the client to again install java.
I mean my jar should work in any system irrespective of the OS and software
requirements.Can anyone please help me
Thanks in advance.

o ya you will have to for the JNI application, actually java application need not to be installed they can be directly used by putting them in a directory structure, if you have idea of nix architecture then you will understand the concept.
well why not make a bat file and include the directory address for the jvm installation file and put them all together in a package,
just take care of the licensing part of java :)
you can also redirect the user to the sun site if he dont have a jvm..,

Java application to jar file

I use eclipse and i have a java program which run without any problem,
but when I export this program to jar file(export->java->jar file)
I get the jar file and when I run this jar file ,it run for few seconds then it stop to run,despite in eclipse it run .
I don't know what is the problem

don't appear so when I run the jar it doesn't find the file.this file is neccessery for the project.
I will read the content of this file,So I think after exporting the project I make it with the jarfile and I use this code to read the file.
String lin= is.read(buffer);
Huh?!? Since InputStream.read(byte[]) returns an int, I do not understand how that compiles, let alone runs.
But any way you cut it, that I/O code was utter rubbish.
but also it doesn't find the file.When reporting problems, please [copy/paste any error messages|http://pscode.org/javafaq.html#exact] you are getting.

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:

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 a JAR file in RAD

Hello, I am creating a simple JAR file containing a group of Java classes. It is not an executable JAR file and is simply a way for me to zip up a bunch of classes I want to use in another project. The problem is, after I create it in RAD using the JAR File Export and drop it into WEB-INF/lib in my other project, it shows as a text file in my Java perspective and I can't see any of the classes.
Is there something else I need to do with my classpath or anything like that? I recently put the Jakarta Commons JAR in the same folder and after a refresh, it showed ready to go. What am I missing here?

Rational Application Developer, IBM's IDE. It has a
Create JAR file utility which supposedly makes it
easy. I'd like to use this if I can because there
are a ton of files. I just don't know what I'm doing
wrong after I create it.Not many people here can help with a question related specifically to an IDE. I had a problem in the past when I tried to create a JAR file with Eclipse. After trying to create the JAR file using the command line utility, I was able to better figure out my error. I strongly recommend you do the same, and post any error message(s) you receive here.

How to call a function from a JAR file

Hi ALL,
I am trying to call a Public function from a JAR file from my JAVA
file. Can you please provide an example or suggest a good resource?
Basically my java file Test.Java should call a function called 'export_a_doc' from a JAR file Export.jar. How do I refer this in my Java file and call 'export_a_doc'?
Thanx

Hi,
HERE IS MY JAVA FILE

     Myclass p = new Myclass();
     try {
p.Start_Export(args);
System.out.println("Finished. \n---------------------");
     } catch(Exception e) {
e.printStackTrace();
     public static void main(String[] args) {

Hi Shane,
The problem appears to be an issue where the directory created is called "JavaTask" but the jars are trying to be placed into "JavaTasks".
Note the "s" appended at the end.
If you manually create the JavaTasks directory then run the tool, it should work.

Jar files are not exported while PAR Export

Hi Experts,
When I am exporting as PAR file, in the par file I am not getting the jar files, which I am adding as external jar files in the java build path - Libraries
Please tell me the solution. urgent...
Regards,
Shyam

Step 6 makes your third party jars available during runtime on your server since you put the dependency to runtime. I don't think you need/can reference your j2ee server dc in the portalapp.xml.
Summary of the link I sent you:
1. Create an External Library DC
2. Copy all of the Jars I needed to the libraries folder of this DC
3. Create two Public Parts (right click on the jar files in Package Explorer)
i) compilePart (with purpose compilation)
ii) assemblyPart (with purpose assembly)
4 Create a new DC of type J2EE Server Component / Library
5. Add a Used DC to the J2EE Library, reference the compilePart from previous step, and set Dependency type to Build
6. Add another Used DC, reference the assemblePart, this time select both Build and Runtime Dependency Types
7. Build and deploy.

Exporting JOGL project in Eclipse to an executable jar file

I'm currently using Eclipse on Windows as my IDE and I've gotten [JOGL |https://jogl.dev.java.net/] to work on it, however if I try to export the project (I've just got a simple example that runs perfectly through eclipse) to an jar file (either the JAR or Runnable JAR option) the jar file doesn't do anything. If I go to the command line and type "java -jar <the jar file> -Djava.library.path=<where the library files are>" it gives this error:

Ok, sounds like it would work, although I've never done much with loading libraries like you describe, so I could use some extra notes on it.

Export a "FAT" Jar file

Hi all.
I created a new Java project as a DC in NWDS. This project references jars stored in a library DC with in the same SC.
I am trying to export the java project as an executable jar. The jar will export, but when I try running the Jar, main throws an exception. I have tried updating the build path in NWDS with no luck. I am able to get the jar file to run from the command line if I include the class-path to each external jar. I believe the issue is that the external jars from the library DC are not being included in the executable jar.
Does anyone know how to export a fat jar file which includes the external jars?
Thanks
Ryan

Glad you found an answer, the issue you were having sounds similar to mine (using 3rd-party jars for axis / wsdl4j). According to SDN docs, you create an external library to wrap the jars (sounds like you did). In your public parts for the external library DC, you need to create both the COMPILATION and ASSEMBLY public parts (both representing the jars) and grant access to them from your consuming DC. Sounds like you did that too, I certainly did.
In my case, I had:
SC
    DC -> extjars
      libraries -> contains qname.jar and wsdl4j.jar
      extjars_assm_pp -> ASSEMBLY public part ref's both jars
      extjars_comp_pp -> COMPILATION public part ref's both jars
    DC -> wsdl4jEJB -> references javax stuff in wsdl4j.jar
      dependencies -> extjars:extjars_comp_pp
    DC -> wsdl4jEAR -> packages the extjars and the wsdl4jEJB
      dependencies -> extjars:extjars_assm_pp
    ...Web Dynpro DC that uses the wsdl4jEAR to import the EJB model...
The trick to making the wrapped jars appear in the compilation command line for the DC deployment of the wsdl4jEAR (from Development Infrastructure perspective) was adding the ASSEMBLY public part reference to the wsdl4jEAR dependenciens. Also, the SAP doco was a bit confusing; on the extjars project the doc states to add the jar files to the public part. Be sure to add the jar files as Archives and not as regular Files (otherwise, the jars aren't added to the buildpath during DC deployment build).
Hope this helps someone else if it doesn't actually pertain to the OP's issue, it would have saved me a bit of digging and debugging...

Exporting to a jar file in eclipse environment

Hi all,
I am using eclipse as my IDE to develop my swing application. The trouble is the gui reads from a file to get the names it has to store.
When I convert it to a jar file, and execute it the names do not appear. I am guessing that it cannot find the file. Can I not export a file that I imported into my project and send it as part of the jar file? How do I get around this?
Thanks, in advance.

How are you loading the files?
You should try to load your files using their absolute path.
To find the absolute path of your jar application, you can use:
String dir = System.getProperty("user.dir");Then, if the list is in the same directory as your app, you use:
File file = new File(dir+"/list.txt");-----------------------------------------------------------------------
Just a note. If you need to read a file that�s packed inside your .jar application, then you need to read the file using getResourceAsStream. For more information, read this thread
I hope it helps

Problems with exporting a .jar file

Hi there,
I'm working on a small java game and wanted to export in as a jar file.
The program runs fine in the IDE and it generates the jar without any warnings.
However, when i try to execute the jar, it simple "blinks" the basic frame and exit.
A better description might be, that it looks like the Jframe opens, but then closes again quickly.
I'm using Eclipse as IDE, and follow the Export wizzard.
My project is devided like this:
package : framework.
package: sound.
package: sprite.
folder: sounds.
folder: sprites.
I'm guessing it somehow can't find the images, but as i said, it runs fine in the IDE.
My MANIFEST looks like this:
Manifest-Version: 1.0
Sealed: true
Main-Class: framework.EagleFlight
Hope you can help.

Hi,
Thanks for your answer.
I can export it from Netbeans, but not Eclipse.
However, from Netbeans I get no sound, when executing the jar.
Anyway, I'm happy enough with the exporting, now I just need to get sound, for which i have
made another thread here.

Exporting jar file

Hi ALL,
How to export the jar file for java project?
I have done it using build path but its not taking the class files at run time.
iam getting error at run time.
can any one help me with this????
Regards
Divya

Hi,
I think you have to include the particular .jar file in your classpath to get out of that error.So in studio goto the particular project and goto the "lib" folder.
Import the jar file form your local system to this folder.Deploy it to your WAS server and run it.
You should be able to run without error.
Hope it helps.

How to create a jar file as a library in java?

Let me put it simple: rb.java is already put under /home/jiane/rb/rb.java;
the tar file rb.tar being located under /mylib/rbcore/, the test client is put under /home/jiane/test.java. now rb.java looks like
//// rb.java
import java.until.*;
public class rb {
%>jar cvf /mylib/rbcore/rb.jar /home/jiane/rb.class
test.java as below
//// test.java
import mylib.rbcore.*;
import java.until.*;
class test {
%>export CLASSPATH="/mylib/rbcore/rb.jar;."
%>javac test.java
%>test.java:1 package mylib.rbcore does not exist
so, how to make adjustment to rb.java & test.java so that I can make use of jar file rb.jar. please shows the steps to do. thanks a lot.

import mylib.rbcore.*;This assumes the package mylib.rbcore and imports all its classes.
But the source of the class does contain package statement, so the class is in the default package.
