ya, but what i want to do is just to write a file to a directory whre the jar is located, So far way it'll write the file into the present working directory. Finding the JAR's location takes a bit ore thought.
not inside the jar, Which you can't anyway. But it dosn't matter at all here.
i cant get it compile, sorry for not giving a clear question, i was asking for a way actually, thanksAnd I actually gave you a reply about what's wrong.

Orion-ejb-jar.xml is overwritten every deployment and not using from .jar

My application is an ear file containing a single jar and a war.
My configuration looks like:
/applications/<appname>/myejbs.jar
within myejbs.jar, exists meta-inf\orion-ejb-jar.xml
Every time I redeploy (copy .ear into /applications and restart server) a version of orion-ejb-jar.xml is copied into /application-deployments/myejbs/orion-ejb-jar.xml but it is not the version that I bundle within my jar. It appears this is the auto-generated version.
Why is this file being overwritten? I thought it should detect if a version of orion-ejb-jar already exists and leave it intact if so. Is there a config setting I've missed somewhere?

Well, we had the some problem.
We solved it when we wrote in the orion-ejb-jar.xml deployment version for actual oc4j.
example orion-ejb-jar.xml for oc4j 904:
<orion-ejb-jar deployment-version="9.0.4.0.0">
or
<orion-ejb-jar deployment-version="1.5.0">
example orion-ejb-jar.xml for oc4j 903:
<orion-ejb-jar deployment-version="9.0.3.0.0">

How to use a jar from a external library DC Project?

I followed the steps of how to create DC, External Library Project, which contains the jar I want.
I understood that this type of project can't be deployed so I build and deployed other DC Project from the type J2EE server component Library and added it to it's public part. What do I do next, to actually use the jar and it's imports?
Thank you,
Meytal.

Not able to access javaFx charts from a remote system after using ext. jars

We are facing following issue. Any recommendations to resolve these issues are highly appreciated.
1. Not able to access javaFx charts from a remote system (More details at the end of mail).This is high priority requirement as we have a web based reporting application and users access it over our static IP address.
We are using Java Fx charts in our web application where we built jnlp and jar files in a separate fx project and kept jar and jnlps inside our web project.
It is working fine when we did not used any external jar files and remotely it is accessible. But when we used external jars our project is running on local
system but remotely it is not working due to some path settings. We modified jnlp files where entry of jar files exists and modified the jar path as per our
project. But still it did not work.
Before using external jars inside our java fx project my jnlp looks like:

Using a JAR file as a project file

My application allows the user to create projects. Previously, a project file was simply an XML file. Now, a project file needs to also contain many images.
I thought it would be a good idea to simply use a JAR file as my project file.
Since I've really never really worked with JAR files and the java.util.Jar package directly, I have a few questions.
1) Would it be better just to simply store the images as binary in the XML file? I just spent a good amount of time making the XML file very readable so I thought it would be better to keep the images separate while still having a single "project" file.
2) Is there anything inherently wrong with the way I'm working with the JAR file in the code below?
Simple XML file:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE project [
<!ELEMENT project (img+)>
<!ELEMENT img EMPTY>
<!ATTLIST img src CDATA #REQUIRED>
]>
<project>
     <img src="blah.jpg"/>
</project>

import java.util.jar.JarFile;
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.DefaultHandler;
public class LoaderTest {
    private String imageName;
    public LoaderTest() {
        InputStream i = null;
        JarFile jf = null;
        try {
            jf = new JarFile("project.jar");
            i = jf.getInputStream(jf.getJarEntry("project.xml"));
            // Here's my simple XML parser to load the project and images
            SAXParser parser = SAXParserFactory.newInstance().newSAXParser();
            parser.parse(new InputSource(i), new DefaultHandler() {
                @Override
                public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
                    // Right now we only care about images
                    if (qName.equalsIgnoreCase("img")) {
                        imageName = attributes.getValue("src");
            // Load the image from the inputstream

            if (i != null) {

}Thank you!

1) I also think it's much better to keep your images separate from your XML, this prevents a lot of in case you just want to read XML data
2) What's exactly going wrong here? For the project.xml, make sure it's not inside a directory within the JAR file, or else the variable i will be null. Otherwise it looks fine..

Loading file from jar in webstart 1.5.0_16

Hello all,
We have recently updated form 1.5.0_15 to 1.5.0_16. Since the update, our application is bombing when it attempts to read an xml file from a jar in cache.
JDOModin.xml.XMLFileReaderError in building: C:\Documents and Settings\dave.frank\Desktop\jar:lookups\version.xml (The filename, directory name, or volume label syntax is incorrect)
org.jdom.JDOMException: Error in building: C:\Documents and Settings\dave.frank\Desktop\jar:lookups\version.xml (The filename, directory name, or volume label syntax is incorrect)
     at org.jdom.input.SAXBuilder.build(SAXBuilder.java:306)
     at org.jdom.input.SAXBuilder.build(SAXBuilder.java:617)
     at odin.xml.XMLFileReader.readFile(XMLFileReader.java:53)
     at odin.xml.XMLFileReader.<init>(XMLFileReader.java:40)
Clearly the path to the jar file is incorrect.
The url is retrieved like this:
private URL getURL(String filePath)
        URL url = getClass().getResource(filePath); // relative path "/lookups/version.xml"
        return url;
} This worked fine in the previous version. Any help would be much appreciated.

Hi Andrew,
We are having huge problems fixing this, and have spent quite a while searching the forums for info about it. The closest I've got is two posts where you mention that there are other posts. I can't find them.... Bloody annoying that Sun hasn't updated the webstart FAQ to tell people how to get around this very annoying problem.
By the way, if you google 1.5.0_16, your post comes up as the second hit.
Any pointers to threads that offer solutions to resource loading from Jars (images, auth.conf etc) when using webstart, now that it's broken in 1.5.0_16??
Any help would be greatly appreciated!
Thanks,
Craig

Get Images from jar. getResource() not working

I've read some of the posts in the forum and I've tried the solutions but still cant get the images in my program.
I'll write all the things I've tried (All of them works fine when I run them from bluej):
1- The code used in the jar files in demo folder of jdk:
/** Inside the main class: */
private static ResourceBundle resources;
    static {
        try {
            resources = ResourceBundle.getBundle("resources.Recursos", Locale.getDefault());
        } catch (MissingResourceException mre) {
            JOptionPane.showMessageDialog(new JFrame(), "ResourceBundle not found","Error",JOptionPane.ERROR_MESSAGE);
            System.exit(1);
public String getResourceString(String nm)
        String str;
        try {
            str = resources.getString(nm);
              } catch (MissingResourceException mre) {
            str = null;
        return str;
    public URL getResource(String key)
        String name = getResourceString(key);
        if (name != null)
            URL url = getClass().getResource(name); // Here is the exception
            return url;
        return null;
    public ImageIcon loadImage(String image_name)
        URL image_url = null;
        try
            image_url = getResource(image_name);
            if (image_url != null)
                return new ImageIcon(image_url);
            else
            return null;
        }catch(Exception e)
            JOptionPane.showMessageDialog(new JFrame(), e.getMessage() + "In load Image","Error",JOptionPane.ERROR_MESSAGE);
            return null;
/** Inside the constructor */
abrirButton = new JButton(loadImage("open"));
}//End of the class}
The ResourceBundle is a file named: Recursos.properties and it's in a folder inside the folder of my *.class and *.java And have this information:
Title=Recursos
ElementTreeFrameTitle=Elements
ViewportBackingStore=false
open=resources/open24.gif
save=resources/saveAs24.gif
cut=resources/cut24.gif
copy=resources/copy24.gif
paste=resources/paste24.gif
analisis=resources/bean24.gif
This one, runs with the jar, but the images are not in the buttons and I get the Dialog message telling me that there was an error in loadImage. Check that method. I used this dialogs to track the error and the exception it's generated by:
URL url = getClass().getResource(name);
in public URL getResource(String key) method.
2- I also tried to follow the instructions of this article that describes how to get resources from jars:
http://www.javaworld.com/javaworld/jw-07-1998/jw-07-jar-p2.html
This is the first page of the article:
http://www.javaworld.com/javaworld/jw-07-1998/jw-07-jar.html
And I did something like this:
/** Inside constructor */
abrirButton = new JButton(new ImageIcon(getImageFromJAR("Imagenes/open24.gif")));
/** Inside of my main class */
public Image getImageFromJAR(String fileName)
           try{
           if( fileName == null ) return null;
           Image image = null;
           Toolkit toolkit = Toolkit.getDefaultToolkit();
            image = toolkit.getImage( getClass().getResource(fileName) );
            return image;
            }catch(Exception exc){
                JOptionPane.showMessageDialog(new JFrame(), "Exception loading the image","Error",JOptionPane.ERROR_MESSAGE);
                return null;
...The images in this one are in the folder Imagenes inside the folder of my *.class and *.java
This one work fine in bluej too, but the jar... It doesn't even start.
3- And the last one.
abrirButton = new JButton(new ImageIcon(getClass().getResource("Imagenes/open24.gif"));Works fine in bluej, not running in jar.
Am I doing something wrong? Please somebody help me.
thanks in advance

Are you putting the image files inside the jar? If you are, then use "jar tf jarfile.jar" to display the contents of the jar and make sure the files are there and inside the right directory. If you are not, then you can not use getClass().getResource() from a jar file because it will look inside the jar file.
If you are getting an error message, please post it.

CommandAction works through OnDeviceDebug, but not when installed from jar

Hi everybody,
I'm trying to run a HelloMIDlet example and if I run it on emulator it works fine, also when I run it on mobile through OnDeviceDebug from eclipse it works fine, but when I install a jar file and run the application it ends with Application Error message and it exits. I found out that the problem might be in the CommandAction method, because when I use this:
public void commandAction(Command c, Displayable s) {
          notifyDestroyed();
}then the application works also when installed from jar, but when I use this:
public void commandAction(Command c, Displayable s) {
   String label = new String("Exit");   //just for test
   if (label.equals("Exit"))
     notifyDestroyed();
}then it ends with Application Error right after I run the program (and it works when I use OnDeviceDebug). I'm using jdk1.5.0_06 and WTK from Sony Erricsson (my target device is W800i, which supports CLDC1.1 and MIDP2.0)

And I'm unable to debug it because when debugging then it works normally. Also I tried to recompile the BluetoothDemo and the same error(and works through OnDeviceDebug). And when I installed the jar file, which is originally distributed with BluetoothDemo then it worked. When I compared original jar file and my jar file then the only difference was in the size the class files (class files compiled by me were bigger then the class files in original jar file (which work)).
Any ideas guys and girls?

I tried that approach but it doesn't work either. I think maybe my directory structure is wrong.
C:\IRS\IRS.jar
C:\IRS\irs.hs
referenced: jar:file://C:/IRS/IRS.jar!/irs.hs
Am I doing this right?

How to use other jar with my executable

Now I created executable jar file for my application but it works wrong. I don't know what dependencies shall I setup in JBuilder
Can somebody help how can I run my application from jar file and I will use BC lilbrary without problem ?.
What all shall I setup for correct work ?
Thanks

Hello
I created new project(Frame application) in JBuilder 2006, Im using mentioned library therefore I put it into reguired libraries in project setting. When I run application through JBuilder (F9) it works fine.
Now I would create executable jar file from my project, which will use this mentioned library. My project has one class CMTModule.class with main function. I created jar file via achrive wizard(AppletJAR). There are options of dependency rules in this wizard, so I choose Includes dependencies. Then I created manifest file and insert this item Main-Class: cmt.CMTModule.
My application start but works wrong , I mean that there is problem with necessary library is not imported. How can I set up it in order to my executable jar can use this library without problems, because in JBuilder all works fine.
What's is wrong ?
Thanks

Exception while a session been lookup on weblogic 10.3.3 using wlclient.jar

Hi,
I am upgrading to weblogic 10.3.3.
I have a client that downloads the required to the client machines using Java web start 6.
I am using wlclient.jar at the client side.
When I am trying to lookup for a session bean it is throwing the below exception at the client side.

I have checked the server logs and the server is able to receive the request from the client and fetching the required details.
I am sending these details to the client by adding to a Vector.
I have observed one more thing, the same is working in other machine which is in another network.
I have also tried with the other wl*.jar s but giving different exceptions.
My server classpath consists of weblogic.jar.
Do I have to include the client jars in my server classpath?
Please suggest me how to resolve this.
Please help me here :)

Thanks for your time, :)
I have tried all the three wl*client jars, but no use. :(
Got the same error for wlclient.jar and wlfullclient.jar.
And for wlt3client.jar I got some different error which is very strange...

ClassNotFound in case of class from jar in lib folder

Hello,
I get an application that I have to deploy on Weblogic AS. It is big ear with couple of wars inside. Let's say it is bigApp.ear.
It is deployed and state is Active. When go to browser and try to run an application I get an error. In logs I found ClassNotFoundException. The error is related to a class, let's say: com.some.package.Abc - I have this class in a jar file, let's say someFile.jar and it is in a folder WLS_FOLDER\samples\domains\wl_server\lib where:
- WLS_FOLDER is my WLS installation folder
- wl_server - name of my domain where I deploy an application.
I wrote a small application (simple form), let's say simpleApp.war. The application uses the class com.some.package.Abc, but the class is not put into the war (WEB-INF/lib) of my small aplication (I use Maven and dependency to someFile.jar has scope provided, so simpleApp.war does not contain it). The result is that simpleApp works fine and there is no error in logs. It creates an instance of com.some.package.Abc and correctly display toString() of the instance of the class in a browser. So this means that application simpleApp is able to see and use classes that are inside jars in WLS_FOLDER\samples\domains\wl_server\lib folder.
So my guess is that there is something in bigApp.ear but I don't know where to search. I read about class loaders hierarchy in Weblogic and Class Loader Filtering. But I have looked inside every weblogic.xml in bigApp.ear and wars that are inside and there is no filter on "com.some.package" or "com.some" or "com" only different packages.
Is there any other mechanism in Weblogic that could block the visibility of classes from jars from lib folder of domain to the applications that are deployed in that domain??
Regards

Hi,
Place that something.jar file under Domain_Home / lib folder and restart the server it will included with in the classpath and your app will able to pick the class without any issue.
Regards,
Kal

Problem loading Applets from Jar files on 64 bit machine

I am developing an applet (extends Applet but uses swing components) using JDK 1.6 (Though these problems still happen in JDK 1.7) and I am unable to get the applet to load on a 64 bit machine in most cases. The web server(s) are running on localhost and I am connecting on the same machine using a local network ip address (such as 192.168.*.*)
Below are all of my test results. Can someone provide a suggestion for repairing this? The Windows Server machine is a clients computer I access to it via remote desktop but I can't do much with it though I do have administrator rights. The Windows 7 machine is my development platform so I have been able to do extensive testing on it.
This problem is presenting in the following environments when trying to load an applet from JAR files in a HTML document using the Applet or Object tag.
Windows Server 2008 (Intel Chipset)
Tested Browsers:
Internet Explorer 9 (32 bit) - Shows it is blocked by default then simply shows an x when loaded from a web page, same result when loading from local drive.
Windows 7 Home Premium (AMD Chipset)
Tested Browsers:
Firefox 6.0.1 (32 bit) - Java logo shows with spinner, after a few minutes there is finally an error that a class in the jar was not found
Internet Explorer 9 (32 bit) - Java logo shows with spinner, after a few minutes there is finally an error that a class in the jar was not found
Internet Explorer 9 (64 bit) - Java logo shows with spinner and most of the windows desktop manager freezes, keyboard is the only thing that responds so you can alt-tab to another app to regain control of the desktop.
Chrome (32 bit) - Java logo shows with spinner, after a few minutes there is finally an error that a class in the jar was not found
The only way I have been able to get a Java applet to run on a 64 bit machine are the following ways.
Firefox 9 nightly (64 bit) works perfectly! Go Firefox!
Internet Explorer 9 (32 bit) loading directly from drive (c:\...)
Chrome (32 bit) loading directly from drive (c:\...)
Firefox 6.0.1 (32 bit) loading directly from drive (c:\....)
Can someone please help! I've been fighting with this bug for over a week and I can't find anything that will solve it, I have noticed that in some cases if my jar has very little code in it than it will run on the server, but the minute I start adding things to it the jar won't load anymore.

To clarify...
1. You have tried it on 32 bit machine? Exactly which OS?I tested this on Windows Vista Business which is in 32 bit mode and the applets run without any problems
>
2. Your only 64 bit tests have involved 2008/Win7?
If so then I would suspect something with windows not java. Probably permissions.
The web server(s) are running on localhost and I am connecting on the same machine using a local network ip address (such as 192.168.*.*)
Yes, I haven't tried running the jars on other operating systems.
>
I don't understand that. If you are running on localhost then you should connect to localhost. If running on an IP then you should connect to that. Perhaps you meant that you have tested using both of those?I'm testing using the lan ip address but I'm connecting from the same machine. I've tried localhost and that didn't work so I tried lan ip since that will likely have a different java security context than localhost. At first I was blaming the IIS server but I downloaded the jar directly and using HTTP fox was able to verify that the jar is being sent with the correct mime-type and that the server can upload the jar file without a problem. This leaves me to believe the problem is with Java.

Problem in using wlclient.jar

Hi
I am getting a problem while doing jndi lookup .It's throwing No_permission exeption .
I have figured out that the problem lies in using wlclient.jar as it uses iiop proptocol inside for lookup .
We do lookup from several servers .One server needs credentials for lookup and another doesn't need .
So the problem arises when i do a lookup with no credentials(As it's not required for a particular server) after a lookup with credentials(As it's required for that server) . These two lookups happening in same thread .
There is no problem occuring while using only weblogic.jar .
I think here the subject associated with a thread doesn't change when i give no credentials .
I have tried Security.runAs(....
But it's throwing exception Subjectmanager not installed .
Any help ..

Can't get ResourceBundle from jar.

Dear all,
I have problem in geting properties from file included in jar file. I try to do it by calling mthod ResourceBundle.getBundle("bundle"), where bundle.properies is the file in jar. When I run the programm by calling :
java -jar dist/properties.jar
I have the following rsult on the console:
Exception in thread "main" java.util.MissingResourceException: Can't find bundle
for base name bundle, locale pl_PL
at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:712)
at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:683)
at java.util.ResourceBundle.getBundle(ResourceBundle.java:546)
In case I run this program, using not jar'ed classes everything is ok.
P.S. the manifest file of the jar is:
Manifest-Version: 1.0
Created-By: Apache Ant 1.5.1
Main-Class: PropertiesLoader
Thanks in advance for all answers.
Daniel Kwiecińśki

According to ResourceBundleAPI:
Calling this method is equivalent to calling
    getBundle(baseName, locale, this.getClass().getClassLoader()),
except that getClassLoader() is run with the security privileges of ResourceBundleTry this code, it will obtain the application's ClassLoader and will enable the location of the properties file in all the classpath defined for it.
        ClassLoader loader = Thread.currentThread().getContextClassLoader();
        resources = ResourceBundle.getBundle(BUNDLE_BASENAME, locale, loader);Good Luck!
