GetClass().getResource() error from jar file.

I am using getClass().getResource("../images/image.gif") to refer to a resource and load it into the ImageIcon. So that my resource's url is dynamic and be got at runtime. It is working fine when I run my program, but when I exported my application into a jar file then while trying to execute the jar file using the
java -jar program.jar command it is giving the following error (Stack trace)
Exception in thread "main" java.lang.NullPointerException
 at javax.swing.ImageIcon.<init>(ImageIcon.java:138)
 at source.HashCalculator.<init>(HashCalculator.java:130)
 at source.HashCalculator.main(HashCalculator.java:2021)

The solution to this error is to include in jar the location of the *gif file(ex: yourpath/images/yourimage.gif) ..... jar cmf yourmanifest yourjar yourclass yourpath/images

 Another question, I used a iplanet web server as a proxy server with a
 cluster of two weblogic servers pluged in, although I set
 weblogic.properties to round-robin, however, when I run a fibonacci servlet,
 it does not do the round-robin. It always go to one machine for a lot of
 times. Any idea?
 Thank you for your help.
 Tom


May i presume that your cluster is configured on a shared file system?.
 I have seen this problem only if you cluster is configured on different machines
 and if the directory structure is not identical.
 let us know..

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.

Error opening jar file

I'm using WLS 5.1 SP8 on NT 4.0 and trying to setup a cluster. The cluster
 starts fine except when I try to deploy a session bean that is marked as
 clustered. I get an error about reading a jar file
 (D:/weblogic/mycluster/server196/tmp_deployments/ejbjar1559.jar) that WLS
 created when the server started. Every server is getting this error and I
 tried setting up the same paths (D:\weblogic) but it doesn't matter. Any
 ideas?

 did a bug of this magnitude
 get past QA. :(

Loading library from jar file

Hi all,
My question is can we load library from jar file using System.load() method.
ex:
myJar.jar
|
|----com.test.common.Util
which conatins a method to load library from jar file itself, before that i used to load from File
|---libraries/MozillaParser/......
Iam able load from Local system,
File parserLibraryFile = new File("libraries/MozillaParser" + EnviromentController.getSharedLibraryExtension());
File mozillaDistBinDirectory = new File("libraries/mozilla.dist.bin."+EnviromentController.getOperatingSystemName());
MozillaParser.init(parserLibraryFile.getAbsolutePath() , mozillaDistBinDirectory.getAbsolutePath());
but i am unable to load from jar file
URL url = ClassLoader.getSystemClassLoader().getResource("libraries/MozillaParser" + EnviromentController.getSharedLibraryExtension());
URL url1 = ClassLoader.getSystemClassLoader().getResource("libraries/mozilla.dist.bin."+EnviromentController.getOperatingSystemName());
MozillaParser.init(url.toString(), url1.toString());
Thanks in advance.

That's a really confusing post.
The easiest way to make sure you can use the classes in a jar file is to copy the jar file to the "/jre/lib/ext" subfolder of your JDK. These classes will be visible to all applications.

Problem loading image from jar file referenced by jar file

First, I searched this one and no, I didn't find an answer. Loading images from jar files has been pretty much done to death but my problem is different. Please read on.
I have my application, a straight up executable running from Eclipse. It uses a jar file, call it JarA. JarA launches a GUI that is located in another jar file. Call it JarB. To recap:
My application calls JarA -> JarA loads classes from JarB -> JarB looks for images to place in a GUI it wants to show on the screen
When JarB goes to load an image the following happens:
java.lang.NullPointerException
 at sun.misc.URLClassPath$3.run(URLClassPath.java:316)
 at java.security.AccessController.doPrivileged(Native Method)
 at sun.misc.URLClassPath.getLoader(URLClassPath.java:313)
 at sun.misc.URLClassPath.getLoader(URLClassPath.java:290)
 at sun.misc.URLClassPath.findResource(URLClassPath.java:141)
 at java.net.URLClassLoader$2.run(URLClassLoader.java:362)
 at java.security.AccessController.doPrivileged(Native Method)
 at java.net.URLClassLoader.findResource(URLClassLoader.java:359)
 at java.lang.ClassLoader.getResource(ClassLoader.java:977)
 at org.cubrc.gmshell.gui.MainWin.preInit(MainWin.java:152)
 at org.cubrc.gmshell.gui.MainWin.<init>(MainWin.java:135)
The code from JarB that loads the image looks like this:
 URL[] oSearch = {Main.class.getResource("images/")};
 URLClassLoader oLoader = new URLClassLoader(oSearch);
 imgIcon = new ImageIcon(oLoader.getResource("icon.gif"));
 imgMatchRunning = new ImageIcon(oLoader.getResource("gears.gif"));
 imgMatchStill = new ImageIcon(oLoader.getResource("gears-still.gif"));
 imgMagnify = new ImageIcon(oLoader.getResource("magnify.gif"));This looks right to me and JarB certainly has an images directory with those files. But I'm in hell right now because I don't know where to place the images to make this work or if you can even attempt to load images with a dependency chain like this.
Any help very appreciated!

Have you tried to move your image-files out of the jar file and place them in the sam folder as the jar-file? I think that would help.
When you try to load the image-file you get the NullPointerException because the program tries to read a file it can't find. Remember that a jar file IS a file and not a directory.
If you want to read somthing inside the jar-file you need to encode it first.
Have you tried to read the jar-file with winRar. It makes it easy to add and remove files in your jar-file.

Multicast socket receive error: java.lang.RuntimeException: I/O error opening JAR file

I received Multicast socket receive error when I tried to restart the weblogic cluster in our pre-prod box.
          The error message I received lkie this:
          Multicast socket receive error: java.lang.RuntimeException: I/O error opening JAR file from file:/vol01/sites/vinlkup/site/versionc/local_classes/VIN/DeliveryTypeLookupEJB.jar


Yuping,
          What release of WLS w/ service pack are you using? Make sure, if you are using a non-shared file system, to have the same absolute paths to your application on your file systems.

Java.lang.RuntimeException : I/O error opening JAR file

 Hi,
 Cluster configuration : 2 NT boxes WLS5.1(SP6). On one m/c weblogic
 is installed on drive C:\ and on another m/c weblogic is installed on drive D:\.
 i.e. all jars are at two place m/c 1 : c:\weblogic\myserver\*.jar
 m/c 2 : d:\weblogic \myserver\*.jar
 When servers startup successfully, error is coming :
 on the console of m/c 1 :
 java.lang.RuntimeException : I/O error opening JAR file from
 file:/d:/weblogic/myserver/eb_arn.jar
 on the console of m/c 2 :
 java.lang.RuntimeException : I/O error opening JAR file from
 file:/c:/weblogic/myserver/eb_arn.jar
 When both the weblgoic servers are installed on two machines and
 on same drive(c:\), this error is not coming.
 i.e. all jars are at two place m/c 1 : c:\weblogic\myserver\*.jar
 m/c 2 : c:\weblogic \myserver\*.jar
 Regards,
 Jitendra Kumar.


Jitendra,
 This looks like a bug. Please approach support.

Cannot load component from JAR file.

I got the message : cannot load component ... from JAR file. The class must be compiled and must be on the classpath of the project...
I just add a javabean from a JAR file from Palette manager, then drag and drop it, then got this message.
Can anyone tell me what i was wrong ? Thank you.

Hi,
You should paste your error log here to easy for other to help you.
For your scenario, it is a big chance you didn't include the jar file into your classpath, please check.
Thanks.

Reading Images from JAR Files

Hi,
I am having a very difficult time being able to read images from a JAR file via my Applet. I have tried everything that I know about with no luck. The only way I can get this to work is to store the images individually in a sub directory of public_html on the websever. This works, but I would like the images to come down in a JAR file for performance reasons.
I am using Internet Explorer 5.5 for my browser. I checked the options and everything seems to be in order, but......
I would appreciate any feedback that anyone might have on this topic..........
Thank You....

once in a jar file i inserted a image
the jar file on clicking starts an frame.
so the image was for getting that image at the icon place at top and at minimized window
i could not get that image from jar file by new imageicon().getimage();
but i get the image if it is in the directory in which jar file is.....
can one explain the reason

Thanks, Valerio

Hi Howard,
thank you for your post.
I actually new about the problems with the jvm version. Still i wanted to ask, cause there are different reports on this `java problems` and even though the 1.4.2_08 seems to be the best version (by the way this version is not to be downloaded any longer *sig*), there are people getting all installed with other versions. I couldn't find any regularity in the misbehavior of the servers while installing.
I finally achieved and got everything working ... but very slow. Loading the adminui or BAM features takes very long time (over one minute). Have you already had this delay. Any hint?
Thanks again,
Valerio

App runs in Eclipse environment but not from jar file with no error message

When I upgraded my jre to 5.0 my app does not run. After fixing the properties problem I had a few days ago it is now at least compiling and running within Eclpse
However, when I export to a jar file it runs to a certain point and then just goes away with no error message!!! I've narrowed it down to the exact point where it dies but don't understand why it dies and especially gives me no errors whatsoever. It just goes away.
It is creating an instance of a new class when it dies.
Can someone please help me?

Ok, well it doesn't. Anyway, I'm still having the same problems. I can run my jar file to a certain point and then the application just stops. I know this because I've put come message boxes in the application to let me know where in the app the system is.
It always dies when it is instantiating the new class called HeidiFrame; done by:
HeidiFrame heidiFrame = null;
if I put code in between the above line and before the below line, this code will work fine
heidiFrame = new HeidiFrame();
but if I put code after the above line, nothing happens
As I said this all worked fine until I upgraded to Java 1.5
If you look at http://java.sun.com/javase/technologies/compatibility.jsp there are 23 compatibility issues with the new release. We're using xml stuff so that was my first problem and the code wouldn't even compiile. Once I added in libraries, the code compiled and ran beautifully.
However, when creating my jar file so I can deploy this application , I've discovered that the jar file will only run to a certain point, as I've stated previously. So, that's my problem. Not that I can't run it from the command prompt, which I can't, but it's a gui application. I've tried changing things in the classpath file and the manifest to no avail. Nothing changes. The application starts but when it goes to instantiate the HeidiFrame class, which is the class that actually builds the gui it dies and goes bye bye.

Another question, I used a iplanet web server as a proxy server with a
cluster of two weblogic servers pluged in, although I set
weblogic.properties to round-robin, however, when I run a fibonacci servlet,
it does not do the round-robin. It always go to one machine for a lot of
times. Any idea?
Thank you for your help.
