Pics in a Jar File

Hi everybody,
if I display a picture in an applet running in a browser
, then I use dataUrl to get the pictures without
a security exception.
My question is: Can I put the picture in a jar file,
the same where the applet is, and then open the
pictures with an ImageIcon object, without using
dataURL ??
thanx
Stephan

If the file is included in a jar, you have to access it this way:
URL url=myApplet.class.getResource("MultiMedia/myPic.jpg");
Image myImage=Toolkit.getDefaultToolkit().getImage(url);
where:
myApplet.class is the name of your applet class file
MultiMedia/ is a sub-directory relative to the applet (if applicable_)
myPic.jpg is the name of your image file.

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.

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()

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

Zip/jar files...

I am writing an application that uses a JEditorPane to display HTML pages. I want to let the user plug-in their own pages using a zip or jar file...i.e. the user stores their HTML pages/images in a jar file and my application can pick these up and display them in the JEditorPane. This works fine for the HTML pages but the images are not displayed. Does anyone know how I can get the images of a HTML page to display without writing the page and/or images to the user's machine? In other words how can I access the images in the zip or jar file via the HTML document?

any Browsable Component will not access the Filestructure of a Zipfile
therefore you have to build up a ProxyComponent which will make the Resource accessable
Step 1
Write a Component which can Access Zip Files
Step 2
Build up a Component wich parse the htmlFile and replaces the Image links with an url of a Servlet like <a href = "\pics\Foo.jpg"> to Step3
write a Servlet wich is Named ResourceServlet wich will send the HTML File if no Parameter is given
(the htmlfile is loaded by Component 1 and Parsed by Component2)
and if Parameter obj is given send the requestet image (loaded by component 1)
Effect is, if you request the html File with aBrowsercomponent, the Browsercomponent will load all images afterwards suczessive
Step4
access the Servlet with a JTextField by Using a HTMLenabled variant and specifing the url:
localhost:8080/servlet/ResourceServlet

How does the app know image folder (non class files) wrapped in jar file?

Hi,
I created an jar file, client.jar, which wrap all necessary files, including packaged class files ( in a hierarachy structure), image folder, properties folder, and ext folder (containing other jar files used). When I run the jar file, like
java -classpath c:\tmp\client.jar -jar client.jar
the app does not know where the images go and could not get the properties files. Actually the image and properties files are contained in the same file: client.jar. How can I fix this. I don't want to extract the jar file back to several separated folders and then run it.
Appreciate the help.

Unfortunately you have to make some changes in your code.. to find the pictures you need to replace:
ImageIcon pic = new ImageIcon("pic.gif");
with
URL url = MyClass.class.getResource("pic.gif");
ImageIcon pic = new ImageIcon(url);
where MyClass is the class which needs to load the resource.
I hope this helped you! /Pingu

Gifs in jar files

I have an application that uses some gif files which are displayed using the ImageIcon object. How do i get it so that it can find the gifs within the jar file that the application is packaged in?
Greg

hi,
a jar-file is to use like a directory and with the command 'getClass().getResource()' you get the real directory to your pictures (or other ressources).
ex.
your jar-file contains the following:
/yourLib/YourClass.class
/yourLib/img/pic1.gif
then you can get the pic from your class 'YourClass.class' with the command
....setIcon(new javax.swing.ImageIcon(getClass().getResource("/yourLib/img/pic1.gif")));

Application working under NetBeans but not as a *.jar file

Hello,
recently I found a little problem. I wrote application that shows all available ports in my computer. When I am running this applications under NetBeans it works with no problem - finds all available ports. Then I am building it to the *.jar file. Application is working with no problem but command:
Enumeration PortIds = CommPortIdentifier.getPortIdentifiers();
is not returning any identifiers - PortIds is empty.
Anyone knows a solution for this type of problems? Thanks

Hi Venkatesh,
Few questions.
1. What is your JDeveloper version? (Always better to post your JDev version along with the question, which would help us to help you better).
2. Did you try adding webserviceclient.jar to the classpath? (Search in your JDev installation directory for the location of this jar file).

.jar file is not working properly :developed in NETBEANS

Hi Gurus,
i am using NETBEANS IDE 7.2.
i am developing a project that interacts with databases 10g and COM ports of machine , these all processes are performed by .bat file which i am trying to run from jFramform , code works perfectly .bat file is also called perfectly when i run the project using F6 from the NETBEANS, for testing i placed some dialogue boxes on the form to test it ,
but when i run executable .jar file , form run successfully and dialogue box works perfectly but .bat file is not called by executable .jar file.
this is how i call the .bat file...
String filePath = "D:/pms/Libraries/portlib.bat";
        try {
          Process p = Runtime.getRuntime().exec(filePath);
        } catch (Exception e) {
            e.printStackTrace();
and below is the contents of portlib.bat file
java -jar "D:\SMS\SMS\dist\SMS.jar"
you must probably ask why i am calling a .jar file using .bat file .
reason is that this .jar project sends message using GSM mobile , System.exit(); is compulsory to complete a job and then do the next one ,
if i use the same file to execute this job it makes exit to entire the application (hope you can understand my logic).
that's why i use extra .jar file in .bat file , when single job is completed .bat exits itself and new command is given.
Problem is that code is working perfectly in NETBEANS when i run the project but when i run .jar then .bat file is not working ,
thanks.

Thanks Sir ,
You need to first test an example that works like the one in the article.
There are plenty of other examples on the web - find one you like:
http://javapapers.com/core-java/os-processes-using-java-processbuilder/
I tried this one.
try {
            ProcessBuilder dirProcess = new ProcessBuilder("D:/SMS/SMS/Send_message.bat");
             File commands = new File("D:/SMS/SMS/Send_message.bat");
             File dirOut = new File("C:/process/out.txt");
             File dirErr = new File("C:/process/err.txt");
           dirProcess.redirectInput(commands);
             dirProcess.redirectOutput(dirOut);
           dirProcess.redirectError(dirErr);
             dirProcess.start();
        } catch (IOException ex) {
            Logger.getLogger(mainform.class.getName()).log(Level.SEVERE, null, ex);
as instructed in the article i compiled both the projects at same version or sources and libraries which is 1.7
here is my version details
C:\>javac -version
javac 1.7.0_07
C:\>java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b11)
Java HotSpot(TM) Client VM (build 23.3-b01, mixed mode, sharing)
inside the NETBEANS IDE c:\process\err.txt remains empty and code works perfectly , but when I run executable .jar file( by double clicking on that file in dist directry) then c:\process\err.txt becomes full with this error text and there is no response from calling D:\SMS\SMS\send_message.bat
here is the error text

Unable to load database driver from my applet's jar file

I'm trying to set up an applet that will talk to a MySQL database. I have no problem connecting to the database as I'm developing the code ("un-jarred"), but when I create a jar file of my code to test through a web browser, I cannot connect to the database due to the usual ClassNotFoundException. I have included mysql-connector-java-3.1.12-bin.jar (the current driver) in the jar, but I don't know if I'm supposed to supply some info through an attribute to the applet tag to let it know that the jar contains the driver it needs or if I have to call the driver differently in my code.
Any help is appreciated, thanks.

The simplest approach is always the best. :)Abso-lutely.
Awesome, that worked perfectly. I Included the extra
jar file in the applet tag and now my applet makes
some sweet lovin' to the database.And you have succeeded where thousands have failed. Congratulations.

Crystal Report not works in JAR File

I'm using Eclipse All in one, which includes Crystal Reports.. I Connected my Java program with Crystal Reports and its working properly. Now my problem is that the Report is not working in JAR files.. It throws some exception as

com.businessobjects.reports.sdk.JRCCommunicationAdapter---- Error code:-2147215357 Error code name:internal"
Whats the Error.. I don't know. I think that i may missed some CLASSPATH Files. The included CLASSPATH Files are:

and the mysql-connector jar file
Anybody help me please...

Unable to load database connector
'com.crystaldecisions.reports.queryengine..driverImpl.
DriverLoader
now you have any idea.. pleaseIs that a typo where you have two periods below?
queryengine..driverImplOther than that I don't think anybody here can help you with that. If your classpath includes all necessary JAR files and you are able to access all your resources from within your application JAR file, then I imagine there is a problem with the third-party crystal decisions JAR file or how you are attempting to use it.
My advice to you is to try and contact support with the vendor or provider of this API or possibly try posting on a support forum on their website to see if somebody can help you there.

How to modify a specific class in jar file ?

I've downloaded a jar file for applet, the jar file works fine... but when I extract a specific class file from the jar file and just recompie it from my IDE (Eclipse) without even making any change and then compress again jar class files including the new modified class file instead of the old one (without any modifications to other classes)... then I get
(NoSuchMethodError ) exception whenever methods of other classes are invoked from within the modified class !!
...The manifist file of the jar file reads the following line
Created-By: 1.4.0_01 (Sun Microsystems Inc.)
I thought it means that jar class files were built using JDK 1.4.0_01 ...I used JDK 1.5.0_01 in my IDE...
I thought JRE incompatiblity was the reason of the problem so I downloaded JRE 1.4.0_01 and used it to build this class file... but i got the same exception..
so what is the main reason of the problem ? ...should I make changes to IDX files accompanying applet jar files ??
If no, then how can I overcome this problem and be able to change and rebuild a specific class from this jar file ?
(I cannot rebuild all classes in jar because there are errors I cannot resolve !!)

Could you please clarify: do you want to run your project or a project from an independent jar?
In the first case just select Run Project from the project context menu or select a class with main method and click Run File in the class context menu.
Regarding the second case:
- I don't think there is such a feature in the IDE (running third party jars is not an IDE function). Could you explain why you need this?

How to load a Jar file in the class path?

How to load a Jar file which contains class files, images, etc.. in the classpath without using URLClassLoader.

You don't "load" jars. If it's on the classpath, you can obtain individual resources from it using various methods on either Class or ClassLoader. Do you mean "how to add a jar to the classpath at runtime"? Can't be done without using a classloader, typically URLClassLoader or a subclass thereof. Why you want to not use the proven method is beyond me. Presumably because you don't understand classloading. In which case, forget it.

Sorry i have tried to format the code, but it has changed to �... sorry read this one...
Hello All,
I'm making a Java SQL Client. I have practicaly all basic work done, now I'm trying to improve it.
One thing I want it to do is to allow the user to specify new drivers and to use them to make new connections. To do this I have this class:
public class DriverFinder extends URLClassLoader{
private JarFile jarFile = null;
private Vector drivers = new Vector();
public DriverFinder(String jarName) throws Exception{
super(new URL[]{ new URL("jar", "", "file:" + new File(jarName).getAbsolutePath() +"!/") }, ClassLoader.getSystemClassLoader());
jarFile = new JarFile(new File(jarName));
System.out.println("-->" + System.getProperty("java.class.path"));
System.setProperty("java.class.path", System.getProperty("java.class.path")+File.pathSeparator+jarName);
System.out.println("-->" + System.getProperty("java.class.path"));
Enumeration enumeration = jarFile.entries();
while(enumeration.hasMoreElements()){
String className = ((ZipEntry)enumeration.nextElement()).getName();
if(className.endsWith(".class")){
className = className.substring(0, className.length()-6);
if(className.indexOf("Driver")!=-1)System.out.println(className);
try{
Class classe = loadClass(className, true);
Class[] interfaces = classe.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces.getName().equals("java.sql.Driver")){
drivers.add(classe);
Class superclasse = classe.getSuperclass();
interfaces = superclasse.getInterfaces();
for(int i=0; i<interfaces.length; i++){
if(interfaces[i].getName().equals("java.sql.Driver")){
drivers.add(classe);
}catch(NoClassDefFoundError e){
}catch(Exception e){}
public Enumeration getDrivers(){
return drivers.elements();
public String getJarFileName(){
return jarFile.getName();
public static void main(String[] args) throws Exception{
DriverFinder df = new DriverFinder("D:/Classes/db2java.zip");
System.out.println("jar: " + df.getJarFileName());
Enumeration enumeration = df.getDrivers();
while(enumeration.hasMoreElements()){
Class classe = (Class)enumeration.nextElement();
System.out.println(classe.getName());
It loads a jar and searches it looking for drivers (classes implementing directly or indirectly interface java.sql.Driver) At the end of the execution I have found all drivers in the jar file.
The main application loads jar files from an XML file and instantiates one DriverFinder for each jar file. The problem is at execution time, it finds the drivers and i think loads it by issuing this statement (Class classe = loadClass(className, true);), but what i think is not what is happening... the execution of my code throws this exception

Driver file is not in the classpath !!!
I have tried also (as you can see in comented lines) to update System property java.class.path by adding the path to the jar but neither...
I'm sure I'm making a/some mistake/s... can you help me?
Thanks in advice,

Error while updating a jar file

I am trying to update a jar file using teh following command

however while doing that i get the following error
java.io.IOException: Error in writing existing jar file
at sun.tools.jar.Main.run(Main.java:179)
at sun.tools.jar.Main.main(Main.java:904)

Perhaps some process (your java program perhaps) is still running that has the file open still? You'll need to shut down the process(es) that have it open. Or you don't have proper rights to the directory/file. Not a java issue.

Hi Olivier,
you could try the following approach:
1. Package your JAR files as J2EE Engine libraries and deploy them on it as described here: <a href="http://help.sap.com/saphelp_nw04/helpdata/en/9f/2ade3fc6c6ec06e10000000a1550b0/frameset.htm">Working with J2EE Libraries</a>.
2. Set reference to this library from the application that use them. Depending on your application, refer to the appropriate documentation:
-- reference from a J2EE app -> see <a href="http://help.sap.com/saphelp_nw04/helpdata/en/15/d5d93fe80fed06e10000000a1550b0/frameset.htm">Referencing Libraries in Applications</a>
-- reference from a portal app -> see <a href="http://help.sap.com/saphelp_nw04/helpdata/en/02/788540ae1dbb4de10000000a1550b0/frameset.htm">Referencing Elements</a>
Hope that helps!

Error in updating jar file in windows

Hi...
I am updating a jar file using Runtime.exec() by passing a batch file in it.
While updating the jar file I am getting error like this:
java.io.IOException: Error in writing existing jar file
at sun.tools.jar.Main.run(Main.java:198)
at sun.tools.jar.Main.main(Main.java:1022)
The batch file (upgradejar.bat) is like this:
echo IQuinox NextGen Upgrade Management
cd shared/upgrade/upgrade/IQfullversion/classes
jar uf ../../../../../../jars/ng.jar ./qlc/postmaster/PMStartup.class ./qlc/postmaster/wpm/admin/scheduler/others/OthersScheduleServlet.class
The java code is like this:
Process p=Runtime.getRuntime.exec( "cmd /C start "+upgradejar.bat);
if (p.waitFor() != 0) {
System.err.println("exit value = " +p.exitValue());
Thanks.

I am using the jar file in my program. the jar file name is " _ng.jar_ " which is mentioned in the batch file.
The batch file is here :
echo IQuinox NextGen Upgrade Management
cd shared/upgrade/upgrade/IQfullversion/classes
jar uf ../../../../../../jars/ng.jar ./qlc/postmaster/PMStartup.class ./qlc/postmaster/wpm/admin/scheduler/others/OthersScheduleServlet.class
