FileNotFoundException in jar file

Hi all,
I am new to using jar files, and I am having a problem accessing files within the jar file. I packaged the jar file using Eclipse. The error that I get is:
java.io.FileNotFoundException: Coordinates.txt <The system cannot find the file specified>
at java.io.FileInputStream.open<Native Method>
at java.io.FileInputStream.<init><Unknown Source>
at java.util.Scanner.<init><Unknown Source>
I can fix this problem by copying and pasting the contents of my files (.txt and .gif) into completely new files and replacing the old ones using WinRAR. When I do this, the program runs perfectly. Unfortunately, when I email my program as an attachment or on some computers when I transfer it with a thumb drive, I get the same error message. Because of the patched-up fix that I found, I am wondering if this could be a problem with file permissions?
Thanks a lot!

FileNotFoundException when using a template stored in a jar file

Hello,
Using Jdev 11.1.1.3.0 I have created a JSF page template in a project and deployed it as a ADF Library JAR file. In a second project I added that library and I can see my template in the page templates drop-down. I created a new page based on that template, however when I run the page I get a FileNotFoundException indicating the template file name I created in the first project. Any idea?

Check that the JAR file that was added to your project libraries has the "Deploy by default" check box checked.

SOHT Java Client
The SOHT Java Client requires a properties file. Either start
the application in the same directory as the soht.properties
file, or specify the file name on the command line:
java -jar soht-cleint-<version>.jar c:\soht.properties
So then I do these cmds which produce the exact same error/reply just above; Unable to load..:
j_ava -jar soht-client-0.6.2.jar -client soht.properties_
java -jar soht-client-0.6.2.jar -client C:\062\soht.properties
So then I copy soht.properties to C root and do:
java -jar soht-client-0.6.2.jar -client C:\soht.properties <same error as above
Then from other information I have read I right click on the .jar file, select open with Always open with:
_"C:\Program Files\Java\jre6\bin\javaw.exe"_
Try again.. same problem.
Then I do cmd:
_"C:\Program Files\Java\jre6\bin\javaw.exe" -jar "C:\062\soht-client-0.6.2.jar"_
does nothing, retry the other commands same thing (either nothing or those same replies)
Then I read (http://forums.sun.com/thread.jspa?threadID=5384879) someone had the same problem as I and they solved it by uninstalling all Java/reboot/ then install JDK 6 Update 14 with NetBeans 6.5.1 start NetBeans and then it worked for them.
So I unistalled all Java, rebooted and gave the cmd another try (before re-installing), now a new error, of course:
C:\062>java -jar soht-client-0.6.2.jar
'java' is not recognized as an internal or external command, operable program or batch file.
Then I install Java SE and NetBeans Cobundle (JDK 6u14 and NB 6.5.1) Final Release/ reboot/ open Netbeans/
go to test java page; all is good, run cmds again -and still nothing..

Thank you very much for your time :D_
PS. My computer has been newly reformatted so needing another reformat I'm sure is not the solution.

Thank you very much for your replies Taggert_77 & swmtgoet_x :D
Taggert77_: I have never used NetBeans. I only installed it in the bundle as I had read on another post that somehow installing the bundle magically helped another user with the same problem (he didn't know why it worked after that either).
Before XP SP3 I was able to execute .jar file through cmd prompt. Now I am not.
This file is executable, grab it and you will see. Here is a screen shot (program in front is FlashFXP, behind is the cmd prompt and what should happen):http://www.freeimagehosting.net/uploads/53273b4ddf.jpg
swmtgoetx_: I only did the other cmd's to try to make it spit out something, anything lol :D
The proper cmd is simply: java -jar soht-client-0.6.2.jar
I did give your cmd a try, and it produced nothing :( (just like the other correct cmds)
java -client -jar soht-client-0.6.2.jar soht.properties
Thank you again...the mystery remains
PS. If you do a search for this you'll find an amazing amount of XP SP3 users with the same problem and no solution posted that I could find except one chap that did the unistall install order that I did above).

Images in Jar files

Hi,
I am creating a recipe book application. Everything is exactly how I want to so I am trying to make a jar file with it.
On the first screen that loads there is one image, when I make the jar file it doesn't seem to be able to find the image once I am outside of eclipse and running the jar.
I have created a folder in called resources in my scr folder (src/resources) this is where I am storing the image.
The method near the bottom (private void addPic()) is where I am having troubles.
package recipe1_5;
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
import java.io.*;
import javax.imageio.*;
import java.awt.image.*;
* This provides an entry point into the program
* as well as the first window
* the main() function is at the bottom
public class Main implements ActionListener {
     JFrame f = new JFrame();
     Container p = f.getContentPane();
     JButton newR = new JButton("Add a New Recipe");
     JButton oldR = new JButton("Look Up An Old Recipe");
     JLabel title = new JLabel("Please make a selection");
     public void actionPerformed(ActionEvent e){
          String whichButton = e.getActionCommand();
          if(whichButton.equals("Add a New Recipe")){
               @SuppressWarnings("unused")
               Recipe newRecipe = new Recipe();
               f.setVisible(false);
               f.dispose();
          if(whichButton.equals("Look Up An Old Recipe")){
               @SuppressWarnings("unused")
               OldRecipeChooser orc = new OldRecipeChooser();
               f.setVisible(false);
               f.dispose();
     }//END actionPerformed
     public Main(){
          f.setSize(200,300);
          f.setLocation(500,100);
          f.setTitle("Recipe Magic");
          p.setLayout(new FlowLayout());
          p.add(title);
          p.add(newR);
          p.add(oldR);
          newR.addActionListener(this);
          oldR.addActionListener(this);
          addPic();
          f.setVisible(true);
          f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     }//END contr ChooseWindow()
     private void addPic(){
          try{
               String imgLocal = System.getProperty("user.dir");
               if(System.getProperty("os.name").contains("Windows")){
                    imgLocal += "\\RecipeMagic1_5.gif";
                    JOptionPane.showMessageDialog(null, imgLocal);
               else
                    imgLocal += "/RecipeMagic1_5.gif";
               BufferedImage image = ImageIO.read(new File(System.getProperty("user.dir" + imgLocal)));
               JLabel pic = new JLabel(new ImageIcon(image));
               p.add(pic);
          catch(Exception e){
               JOptionPane.showMessageDialog(null, "Image Load Error","ERROR", JOptionPane.ERROR_MESSAGE);
               e.printStackTrace();
     public static void main(String args[]){
          Main m = new Main();
}//END class ChooseWindowI have tryed this two different ways. The first how it is. And the second with something like this:
ImageIcon ii = new ImageIcon(getClass().getResource("resources/RecipeMagic1_5"));Any insight on how to get the image from inside of the jar file would be great
Forgot to add, it either throws a NullPointerException or a FileNotFoundException in the catch clause of addPic()
Edited by: tyelford on Dec 15, 2010 11:46 AM

Ok, so it works good on Mac, but if I try to use it on Windows it will not load the image,
Here is the code that works on Mac but not windows:
private void addPic(){
          try{
               String imgLocal = System.getProperty("user.dir");
               if(System.getProperty("os.name").contains("Windows")){
                    imgLocal = "resources\\RecipeMagic1_5\\RecipeMagic1_5.gif";
               else
                    imgLocal = "resources/RecipeMagic1_5/RecipeMagic1_5.gif";
               ImageIcon ii = new ImageIcon(getClass().getResource(imgLocal));
               JLabel pic = new JLabel(ii);
               p.add(pic);
          catch(Exception e){
               JOptionPane.showMessageDialog(null, "Image Load Error","ERROR", JOptionPane.ERROR_MESSAGE);
               e.printStackTrace();
     }I get an Image Load Error on Windows, but the same file on Mac runs perfect

Problem deploying connector: META-INF/ejb-jar.xml not found in jar file

          Has anyone seen this problem:
          I built Sun's Blackbox implementation and packaged
          it identical to the BlackBoxNoTx.rar included with
          Weblogic's 'jconnector' sample (even using the same
          ra.xml and weblogic-ra.xml). When I try to deploy
          it, the server reports:
          java.io.FileNotFoundException:
          META-INF/ejb-jar.xml not found in jar file
          I have no idea why the server thinks my connector
          is an EJB. If I deploy the BlackBoxNoTx.rar included
          with the sample, everything works without a hitch.
          The only variable that I'm changing in my BlackBoxNoTx.rar
          is that I build the Blackbox classes myself--otherwise,
          the RAR packagings are identical. Any assistance is
          greatly appreciated since I'm banging my head against
          a wall...
          Thanks,
          -jason


          I was finally able to resolve this one. On the odd chance that someone else encounters
          the same problem, here's what went wrong:
          My RAR file had two directories: 'META-INF' and 'meta-inf'. The first was created
          by the jar tool and contained the manifest.mf file. The second I created manually
          and it contained my ra.xml and weblogic-ra.xml. When I examined the RAR using
          any tools or I extracted the contents, it looked like it only contained one directory:
          META-INF (because NT is case-insensitive).

Error while Building Jar files using [ejbc]

Hi,
I am building EJB's using [ant ejbc] for upgrade from Weblogic 6.1 to Weblogic 10.0. The code gets build fine but when creating the Jar file it is throwing me the following error :-
[ejbc] Loading properties file: /C:/dev/MarketingOne/thirdparty/sms/lib/logging.//config/logging.properties
[ejbc] SMS_ERROR:
[ejbc] Properties:
[ejbc] - Failed to load properties file: /C:/dev/MarketingOne/thirdparty/sms/lib/logging.//config/logging.properties
[ejbc] java.io.FileNotFoundException: C:\dev\MarketingOne\thirdparty\sms\lib\logging.\config\logging.properties (The system cannot find the path specified)
[ejbc] - Either invalid SMS_HOME: /C:/dev/MarketingOne/thirdparty/sms/lib/logging./ or invalid <I>SERVICE</I>_P
ROPERTIES_FILE_NAME
[ejbc] at java.io.FileInputStream.open(Native Method)
[ejbc] please set SMS_HOME using -D option at JVM start up.
Can anybody provide me with a solution for this as the path mentioned for SMS Logging.properties file is correct..??

Actually the folder 'lib' consists of a logging Executable Jar file and the SMS folder consists of 'config' and 'lib' folders. Inside the 'config folder is a logging.properties file.
But Actually I am not getting any idea as to from where this command is being triggered because my targets.xml file does not have any such command whereas it just builds all the files and then creates the jar file.
Is it a problem of using EJB 2.0 in Weblogic 10.0 environment or jdk1.5..??

Why can't I read any of my resources in a jar file?

For an application I was developing, I wanted to create a Binary File using the following code:
DataInputStream in = null;
        try {
            File file = new File(name);
            in = new DataInputStream(
                    new BufferedInputStream(
                        new FileInputStream(file)));
        } catch (FileNotFoundException e) {
            System.out.println("Non-existential File.");
            System.exit(0);
}I am using Netbeans 6.5.1., and it groups my projects so that there are folders for build, src, dist, nbproject inside the project folder. The application that I am developing is a graphics demo that requires the use of several text files to represent the maps, so I wanted to read them using a FileInputStream.
I kept this file, "islandmap.txt", in the src folder in my project. In the method above, I coded my program so that the "name" would be "src\islandmap.txt", and it read from the file perfectly. However, I needed to compile it to a Jar file too. After doing that, the program no longer functioned. I remembered when I used a tutorial long ago that used
URL url = getClass().getClassLoader().getResource(fileName) ... in order to get the directory of the files. That made sense, because a person who is running the program via Java Webstart or a Jar Executable would definitely not have the parts of the program located in the same directory, so the code is used to find where the java program is. However, I realized something...
File file = new File( - constructor - )There are four constructors for files, and I only think I could use two. The first is using a string, like I have done before with "src\islandmap.txt." Now, the URL url = getClass().getClassLoader().getResource(fileName) part, it was used before to locate a URL in order to open a buffered image. The constructor for File does not support URLs, but instead supports URIs.I tried converting between the two, changing a URL into a string, and producing a URI from the string. But it did not work, giving me an error that URI was not hierarchical. And that's when I realized that they were certainly not interchangable.
More specifically, here is my code as of now:
public boolean loadMap(String mapName) {
        String path = "src/islandmap.txt";   //This is where the map files are stored
        mapName = getClass().getClassLoader().getResource(path).getPath(); //getPath changes the URL into a String
        DataInputStream in = null;
        try {
            File file = new File(mapName);
            in = new DataInputStream(
                    new BufferedInputStream(
                        new FileInputStream(file)));
             //code to actually read from the file goes here
        } catch (FileNotFoundException e) {
            System.out.println("Non-existential File.");
            System.exit(0);
        } finally {
             //close in
}So that is my problem now. I am stuck. For my purposes, I basically must use a stored text file within my jar, but I don't know how to read it. It distresses me that normally, I already know how to open images that are located inside my src folder using URLs, but not any other file requiring a File class to be wrapped within a Buffered Writer/Reader. Could somebody please assist me with this, or suggest an alternative that would also fall under my conditions? I would appreciate it so much. Thank you.

Start with
URL url = getClass().getClassLoader().getResource(fileName)Then observe that URL has a [openStream()|http://java.sun.com/javase/6/docs/api/java/net/URL.html#openStream()] method that will give you an InputStream. Since you are reading text you might want to create an InputStreamReader from which you can do your reading much like you used the FileReader before when you were working with a File.
Class also has a [getResourceAsStream()|http://java.sun.com/javase/6/docs/api/java/lang/Class.html#getResourceAsStream(java.lang.String)] which combines the first two steps into one. Ie use getResource() as you mentioned when you want to get a URL that some other class will use to read (eg an image) or use getResourceAsStream() when you are going to do the reading yourself.

Target to execute multiple junit tests from jar file

I have written a custom selenium framework using JUnit and Selenium, problem I am having right now is our team wants to run the tests inside HP Quality Center (I have no idea or any experience with Quality Center) but if I provide a jar file the them they can execute it inside the Quality Center (Reason to run it in Quality Center is for reporting purpose).
Problem is that I have created my framework in away that You can create multiple JUnit base test files for different tests also keep in mind that these classes dont need main method (This is where the problem when it comes to jaring up ). I have introduced following ant target to run all the test cases.
     <target name="test.selenium" depends="jar" description="target to execute all the selenium tests.">
          <junit printsummary="yes">
               <classpath>
                    <path refid="classpath"/>
                    <path refid="application"/>
               </classpath>
               <batchtest fork="yes">
                    <fileset dir="${src.dir}" includes="**/Test*Selenium.java"/>
               </batchtest>
          </junit>
     </target>above ant target runs without any problem, but when you jar it up you need a manifest and main class, is there away I cant introduce some attribute that can execute all my tests without adding main method to each of them.
Here is my ant target for jar
     <target name="jar" depends="compile"
               description="Generates final jar">
          <copy todir="${build.jar}">
               <fileset dir="lib" excludes="**/*.java"/>
          </copy>
          <jar jarfile="${build.jar}/yukonSelenium.jar"
                    basedir="${build.classes}">
               <manifest>
                    <attribute name="Main-Class" value="com.somepackage.selenium.test.TestAuthenticationSelenium"/>
                    <attribute name="Class-Path"
                         value=". /c:/build/jar/log4j-1.2.15.jar /c:/build/jar/junit-4.6.jar /c:/build/jar/selenium-java-client-driver.jar /c:/build/jar/dom4j-1.6.1.jar"/>
               </manifest>
          </jar>
     </target>And this is how the Test Class looks like, I have added main method in this but once i do this after jaring java -jar myJarfile.jar will only execute just the class i have main method init.
public class TestAuthenticationSelenium extends SomePrivateFrameWorkClass {
     private void init() {
          start();
     @Test
     public void testProductNav() {
            //somecode
     @Test
     public void multipleLogin() throws FileNotFoundException, InterruptedException {
                         //Some Code
     public static void main(String[] args) {
          org.junit.runner.JUnitCore.main("com.somepackage.selenium.test.TestAuthenticationSelenium");
}Please let me know if i should put the entire ant build file.
Thanks for any help.

What i mean is if i have 3 class files in my jar file, and each one of those classes has a main method, how will i be able to execute a class of my choice from that jar file. In manifest files, you specify the main class, but how would i specify multiple classes with main methods, or achieve my objective here.

Jar files............could do with some help

I want to deploy an application I have built along with the JRE it seems creating a JAR file is the way to go. Could somebody confirm this & advise of any other steps that I will need to take along the way. Please take it very SLOWLY and omit nothing.
I have attempted to create and run a JAR file but have met with failure so far let me explain where i am upto.
I have an application with several class files all data or code no image or sound files. class that contains the main method is called
"pStruct". have created a JAR file called "TelDir.jar" succesfully & checked that all required classes are their they are. Next have built the file "mainClass.txt" in notepad have been carefull to get the syntax & case correct & have entered newline before saving file.
Now i think i am merging the text file into the manifest of the jar file
with the line:-
jar cmf mainClass TelDir.jar pStruct.class
this results in an error message as follows
java.io.FilenotFoundException:main Class(System cannot find the file specified).
now I have tried adding .txt to the end of mainClass and the line seems
to execute happily but if i then try and run my amended jar file with:
java -jar TelDir.jar
I get the following response:-
Exception in thread "main" javac.lang.NoclassDef Found Error:GUIFrame
and a about 8 other lines of complaint.
("GUIFrame" being one of my classes in the jar file)
when building the jar file i have not stated each class individually but used the wild card. would this cause a problem. I have also made sure ALL files invloved are all in the same subdirectory.
COULD SOMEBODY PLEASE HELP I AM GETTING A BIT F.R.U.S.T.R.A.T.E.D AFTER MESSING WITH THIS FOR 6 HOURS TODAY!!!!. (calming down now ahhhhhh.)
Hoping somebody can tell me what i am doing wrong
Scott

Have discovered my mistake at the end of the line "jar cmf mainClass.txt TelDir.jar pStruct.class" pStruct is the class containing my main method as stated in the Manifest but it should read all of the classes required to make my application run or * the wildcard.
Things always seem clearer the following day.
When you say post the contents of the Manifest file how can i examine its contents or do you mean the contents of the text file.
Now i have my jar file how do i take this further to enable me to deploy my application along with the JRE onto another machine?
Regards
Scott

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.

Problem in viewing a converted JavaHelp (jar) file (created using RH2002 to RoboHelp X5)

Hi,
I have a javahelp project (compressed javahelp) created using
RoboHelp 2002. The output files are jar files.
The source files are .mpj. When I view the existing jar files
without converting the project to .xpj I am able to view the jar
files.
However, this project needs to be upgraded to RHx5. During
conversion(.mpj to .xpj) everything seems to be working fine and
the javahelp files are generated. But when I try to view the jar
files nothing is diplayed.
I get the following error. Please see below.
Has anybody come across anything similar? Is there anything I
need to take care of before I upgrade to .xpj? I cannot locate the
glo.xml file in RH.
Best regards,
Urmi

Hi Colum,
Thanks for your reply.
Yes, I have gone through the Peter Grainge's article. It is
indeed very informative and I have installed the JDK and the JH
according to the instructions given therein. My installation seems
complete as the viewer works fine. The JDK version is 1.4.2_18 and
the JH version is 2.0. The environment variables have also been set
accordingly.
All this while I was thinking it is a Java issue so I have
tried out with different JDK versions.
But now I think it can be a tool issue because :
I can view the existing JavaHelp file with the current Java
viewer.(if I do not open the project in X5)
I can view Sun supplied sample jar files with the viewer.
I can create new JavaHelp files with RHX5 and the current JDK
and JH installation and view those files.
I cannot view the JavaHelp file if I convert the .mpj to .xpj
(the generate dialog works fine and says compilation is complete).
The Display button does not display the file. The view
command line command throws up the error mentioned in my earlier
mail.
Would appreciate any pointers.
Best regards,
Urmi

How to Insert a Text File in a jar file?

Hi!,
I have a program which runs smoothly both from the IDE and also from the .jar file when it is on the Hard Disk. When i copied everything onto a CD, the .jar file runs but when it comes to access a text file it pops up the message, which should pop up when a FileNotFoundException is encountered. Now i am using relative paths, in fact i tried to load the whole thing from a pen drive and it works fine as well. I think that if the text file is included in the jar file itself, it might work from the CD as well, but i dont know how to do it. can anyone pls tell me how i can solve this problem?
Thx in advance, Spi_Mlt

OK this might give you some trouble (gave me trouble for a long time) so I will try to help you.
1. in your code load the file as a resources not a FileObject or a local stream, this is what I mean...
A_stream_that_best_fits_your_needs = getClass().getResourceAsStream("fileName");
// something like that...if you don't know streams google it2. put a copy of your text file in the same folder as the .java file that loads it and a copy where the .class file that loads it (if they are in the same directory then it just easier than for you).
3. when compiling the jar include the text file in it!
Hope that helps!

Validating xml-files inside jar-files for JWS

I want to use xml-files inside a jar-file and want to validate them with dtd-files,
located in the same jar-file. This does work, but only as long as the dtd-file is
in the same directory as the xml-file.
For example, I have no problem, with a DOC Type-statement like
<!DOCTYPE questestinterop SYSTEM "ims_qtiv1p1.dtd" >
With this statement, however, one needs an approprate dtd in every directory containing an XML-file of that type.
If however i want to gather the necessary dtd's in a directory one (or more) levels above with a DOCTYPE-statement of the form
<!DOCTYPE questestinterop SYSTEM "../ims_qtiv1p1.dtd" >
I get error messages of the form
java.io.FileNotFoundException: JAR entry Mikro/Marshall/BookQuestions/../ims_qtiv1p1.dtd not found in C:\Dokumente und Einstellungen\wreiss\Anwendungsdaten\Sun\Java\Deployment\javaws\cache\http\Dwiwi.upb.de\P80\DM~vwl08\DMOViSS\DMoviss_current\RMMikro.jar

     at javax.xml.parsers.DocumentBuilder.parse(Unknown Source)
     at oviss.competenceCenter.XMLExpert.setElements(XMLExpert.java:245)
though the dtd-file is in the parent-directory (inside the jar) and the unpacked xml-file can be successfully validated.
Why does this happen. How can one use a single dtd for multiple xml-files (of the same type) in different directories?.
Thanks
Winfried Reiss

In reply to myself, replacing the HTMLBrowser constructor with this;
public HTMLBrowser()
              URL url;
              try
                   // Construct the URL
                   url= this.getClass().getResource('/'+dir+'/'+startPage);
                   setPage(url);
              catch (Exception e)
              System.out.println( "Problem setting help homepage");
             setEditable(false);
             addHyperlinkListener(new LinkListener(this));
        }made it work. This is because seemingly you need '/' at the start of the resouce's path and '/' as the separator, regardless of platform.
I hope this helps someone else.

Problem creating an jar file!

Hello.
I am trying to create an executable jar file using the following command:
jar cmf MANIFEST.MF game.jar *.classHowever, I keep receiving the following error:
java.io.FileNotFoundException: MANIFEST.MF (The system cannot find the file spec
ified)
        at java.io.FileInputStream.open(Native Method)
        at java.io.FileInputStream.<init>(FileInputStream.java:64)
        at sun.tools.jar.Main.run(Main.java:124)
        at sun.tools.jar.Main.main(Main.java:904)Why am I getting this error and how can I correct this?

Did you create a file called MANIFEST.MF? Is it in the same directory you are in now?
And by the way, according to what I see when I run the jar command, you need to specify the jar file first, and then the manifest file:Usage: jar {ctxu}[vfm0Mi] [jar-file] [manifest-file] [-C dir] files ...
Options:
    -c create new archive
    -t list table of contents for archive
    -x extract named (or all) files from archive
    -u update existing archive
    -v generate verbose output on standard output
    -f specify archive file name
    -m include manifest information from specified manifest file
    -0 store only; use no ZIP compression
    -M do not create a manifest file for the entries
    -i generate index information for the specified jar files
    -C change to the specified directory and include the following file
If any file is a directory then it is processed recursively.
The manifest file name and the archive file name needs to be specified
in the same order the 'm' and 'f' flags are specified.
Example 1: to archive two class files into an archive called classes.jar:
       jar cvf classes.jar Foo.class Bar.class
Example 2: use an existing manifest file 'mymanifest' and archive all the
           files in the foo/ directory into 'classes.jar':
       jar cvfm classes.jar mymanifest -C foo/ .
