Problem w/ Netbeans genereted jar file

Hi,
My java application runs fine in the netbeans IDE. I had problems with the jar file it created a while back which turned out to be that i had an older version of JRE still installed. Anyway they worked fine until recently, when i started geting the same message from the virtual machine : "Could not find main class" (I know there's other threads in this forum on this but they didn't solve my problem). The manifest file looks like this:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.2
Created-By: 1.5.0_01-b08 (Sun Microsystems Inc.)
Main-Class: BattleRoyal
X-COMMENT: Main-Class will be added automatically by build
Which is EXACTLY the same as the manifest file in the old jar file that does work.
What other problems could have occured? (I don't need any third party jar files or anything)
Thanks

Hello
I have dealt with similar issues in the past.
The first thing you should check is that the name of the class in the "Main-Class" parameter of the manifest id the full name of the class including the package. For example:
Main-Class: com.acme.MyMainClass
Second, are you sure your packaged application does not need external libraries? this could be the source of the problem.
Last, I would not trust my IDE to make the Jar for me. (Men can open , and close their own Jars!!!, just kidding) I use an ANT task to do the packaging.
<target name="jarFiles" depends="init">
<jar jarfile="${jarname}" basedir="${buildDir}">
     <manifest>
          <attribute name="Main-Class" value="com.acme.MyClass"/>
     </manifest>
</jar>
</target>
I hope this helps and reaches you in time.

Problem in Creating a jar file using java.util.jar and deploying in jboss 4

Dear Techies,
I am facing this peculiar problem. I am creating a jar file programmatically using java.util.jar api. The jar file is created but Jboss AS is unable to deploy this jar file. I have also tested that my created jar file contains the same files. When I create a jar file from the command using jar -cvf command, Jboss is able to deploy. I am sending the code , please review it and let me know the problem. I badly require your help. I am unable to proceeed in this regard. Please help me.

Hi,
I have gone through your code and the problem is that when you create jar it takes a complete path address (which is called using getAbsolutePath ) (when you extract you see the path; C:\..\...\..\ )
You need to truncate this complete path and take only the path address where your files are stored and the problem must be solved.

Problem while loading a jar file into database

Hi All,
We are using Oracle 8.1.5 in Solaris. When I try to load a jar file into the database by using loadjava it gives the following error
Error while processing jar cryptix32.jar
Exception java.io.IOException: Load Java is unable to handle compressed entries: cryptix/provider/Cryptix.class
loadjava: 1 errors
Can anybody suggest anything to overcome this. Thanks in advance.

Problems with creation of JAR file

Hi!
I can't succeed in creating a JAR file for my application.
I've followed the guide at http://java.sun.com/docs/books/tutorial/deployment/jar/basicsindex.html
but apparently im doing something wrong....
I've tried doing an extra Manifest file aswell as "Setting an Entry Point with the JAR Tool" as written in the guide. noen with success however :(
I always get the error "Could not find the main class. Program will exit." from the JVM when I try to run my JAR file.
Structure of my program:
C:\searchpath\moresearchpath\projectname\src\
inside src\ there are 3 packages called; "graphic", "client" and "server".
I want to make a JAR file from the files in the "server" package. The "server" package consists of these following 4 files(and nothing more); "ClientHandler.java", "TestServer.java", "ServerModel.java", "ServerController.java".
"TestServer.java" is my main class!
This is an example of a command I've done in order to try to make a JAR file:
"C:\searchPathToWhereJavaIsInstalled\jdk1.6.0\bin\jar cvfe sgwserver.jar server.TestServer server\*"
This doesn't generate any error. However when I try to start the .jar I get following message "Could not find the main class. Program will exit."
I've also tried creating manifest file manually but without success (with UTF-8 encoding and not double .txt ending on file)
This is how the "Manifest.txt" file has looked when I've tried making one:
Main-Class: server.TestServer
I have used Netbeans 5.5 and Java SE 6 for development
What am I doing wrong? Please help me :(

If I try to run the one generated from Netbeans I get the following error message: "Failed to load Main-Class manifest attribute from C:\searchpath\moresearchPath\projectName\dist\projectName.jar"
The thing is I need 2 JAR files, one that contains the files in the "server" package and one that has all other files. The other one is an applet and the files in "server" package are a standalone application.
How do I get the standalone application's JAR file to work?

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 with images in .jar file

Hi all!
I've got a severe problem when deploying an application via web start:
the images withhin a deployed .jar file are not found.
So far I've tried a number of things to get the images back, none of which are working.
I've found different threads concerning this topic, e.g.:
http://forum.java.sun.com/thread.jspa?threadID=396363
http://forum.java.sun.com/thread.jspa?threadID=465795&messageID=2141351
but sadly, they didn't help me out.
Here is my code I'm using:
private ImageIcon loadIconFromClassLoader(String tszRelPath)
    ImageIcon tIcon = null;
    cCat.info("tszRelPath = "+ tszRelPath);
    // this line simply leads to a crash of the whole application
    //tszRelPath = tszRelPath.replaceAll("\\", "/");
    if(!tszRelPath.startsWith("/"))
      tszRelPath = "/" + tszRelPath;
    cCat.info("modified tszRelPath = " + tszRelPath);
    URL tURL = ClassLoader.getSystemResource(tszRelPath);
    if(tURL == null)
      // this too crashes my application
      //tURL = PlainResourceProvider.class.getResource(tszRelPath);
    if(tURL != null)
      tIcon = new ImageIcon(tURL);
    return tIcon;
}I've also tried
PlainResourceProvider.class.getClassLoader().getResource()PlainResourceProvider is part of the .jar that involves the images.
Of course all the .class files in the .jar file are easily accesible
I would be so thankful, if just anyone could help me to solve this problem.
I am going crazy.
Thanks in advance, Christoph

You should take care of the directory structure according to the package structure.
I for example have this jar:

Problem with addition of jar file to DC

Hi WDers,
I have a DC of type WD.
I'm trying to add com.sap.security.api.jar file to this component so that I can get IUser and work on it.
I have added this security jar file as an External jar file to the DC. But whenever I try to DC->Build, the jar entry is going away. So the Build is failing.
Can you kindly let me know why this is happening?
Or is there any other way to add a jar file so that I can use the IUser interface in my view?
Thanks in Advance
RK

Hello,
Add the Standard DC "com.sap.security.api.sda" from the SAP-JEE. This ahould solve the problem.
To do that follow the steps:
1. Go to the "DC Metadata" option available under the DC.
2. Go to "Used DCs" and choose "Add used DCs" from the context menu which appears on a right click at the Used Dcs option.
3.Select "com.sap.security.api.sda" under SAP-JEE and choose finish.
4. Build the DC to gain access to the IUser and other related classes.

Problem with using external jar file

Hi
I was using mail.jar library for swing application to send and receive emails. It just works perfect when I run with netbeans. But when I run the executable jar file at dist folder it runs but mail related functions doesn't work.What should I do now to make it work with mail features outside netbeans.
thanks

I would expect to see this 'dist/lib' directory contain mail.jar and activation.jar and any other jars that your jar needs. Within your program jar's manifest I would expect to see the Class-Path attribute have relative reference these jars ( lib/mail.jar lib/activation.jar ) and for the Main-Class attribute define your main class.
Given this setup then you should be able to just type -
java -jar yourjar.jarto run your program.

Problem accessing class in jar file

Hello. I am trying to create a jar file from my already compiled classes. I have around 5 packages, and my programs' entry point is in one of the packages, we'll call package A. Each package has its own purpose and package A calls any needed package to perform their task. This works well when I compile, run and all. However, when I create a jar file, it only works with the local package and any calls to another package do not work. How can I get around this? any help will be appreciated

This is the output..

Problem accessing sounds in jar file

Hi,
I have made a program and packed it to a jar file.
Everything works fine in the IDE, so this is purely a matter of jar access.
The jar has 6 folders.
framework (which is one of my packages)
META-INF
sound (also my package)
sounds (my wav files for the program)
sprite (another package)
sprites (my graphics for the program).
I access the graphics in sprites, from a class in sprite and have no problem with it.
try {
               URL url = this.getClass().getClassLoader().getResource(ref);
               if (url == null) {
                    fail("Kan ikke finde ref: "+ref);
               sourceImage = ImageIO.read(url);
          } catch (IOException e) {
               fail("fejl ved load: "+ref);
          }The problem is accessing the wav file in the sounds folder from a class in the sound folder.
try{
               AudioInputStream stream = AudioSystem.getAudioInputStream(new File("Sounds/1999.wav"));
               AudioFormat format = stream.getFormat();
               DataLine.Info info = new DataLine.Info(Clip.class, stream.getFormat(),
                         ((int)stream.getFrameLength()*format.getFrameSize()));
               clip = (Clip) AudioSystem.getLine(info);
               clip.open(stream);
          }I have tried to use the class loader like this (instead of AudioSystem.getAudioInputStream) :
AudioInputStream stream = (AudioInputStream) this.getClass().getClassLoader().getResourceAsStream("sounds/1999.wav");
but it didnt help.
Does anyone have any suggestione?
Please, if all you can do, is paste a link to the java API, save your energy. I have already looked and it was no help, as im still only a student of java.
I would like an actual suggestion, so i can see it work, then i can make work my way through the API from there.
Edited by: Mondariz on May 7, 2008 8:26 AM

Don't try to use a File object to access resources from the jar. You have a working process for accessing the sprites, just use the same process to access the sounds. Only not quite the same method, there's one method which returns a URL and a very similar method which returns an InputStream. I would post the link to the documentation but you asked for us to not do that. Anyway you seem to know where it is.

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.

{ System.err.println(e.toString()); }

Could I ask that, if I stored the MsAccess or any other DBs, will the DB able to do basic operations (Create Update Retrieve Display)?
As the DB is not like a normal Text file.
What I did is that, I didn't include the MsAccess into the .jar file. I just put it beside. The disadvantage is that user ables to open the DB and might do some changes. ;-(

Problems accessing class in JAR file [err = -4000]

Hi, my setup is as follows ....
I have a seq file that is accessing a Java class file, TestStandClient.java. something like
public class TestStandClient
   public String test (String arg)
      String returnVal = "";
      try
         TestClass testClass = new TestClass ();
         returnVal = testClass .test (arg);
      catch (Exception e)
         returnVal = e .toString();
      return returnVal;
TestClass.java is
public class TestClass
   public String test (String arg)
      return arg + " : [Jar object has modified string]";
Now. TestClass is in a seperate jar. When TestStandClient :: test is called i get a -4000 error. From the readme in the Java example file it is described as ....
Error
reading returned string
The
string returned from Java was corrupt. Verify that the return type of the Java
method is a string value.
I have noticed if I take out the call to the object in the jar file then everything works ok.
Could it be a classpath problem? the StartJVM has its classpath
pointing at the folder where the jar is and also at where the
TestStandClient class file is. I also set the classpath for the Java
step to be the same (location of jar and class file)
So, can someone inform me of what support TestStand has for java? Does it support communicating with a class file that itself depends on other JAR files? This is surely the case?
thanks in advance

Dear PCR Barry,
I am afraid that I must agree with my colleague Kostas, who replied to your first teststand post. These are very tricky, indepth issues, and will require quite significant investigation. Furthermore, it will be very difficult for us to answer via the forums as we will likely need more input from yourself. As previously suggested, if you have a Standard Service Program (SSP), you can generate a Service Request by calling or e-mailing your local branch.
Thank you for your time, and I am sorry that I have been unable to help you further,
Best wishes,

Problems with jdbc and .jar files.

I am having a problem with connecting to my database when running my .jar file as an executable.
It connects correctly when I use the java command in command prompt and it also runs correctly when using my IDE.
Is there something that needs to be added to the manifest or in the code it self inorder for the program to find the JDBC driver correctly?

This is the error message that I get:
java.lang.ClassNotFoundException: net.sourceforge.jtds.jdbc.Driver

Error Trace in getConnection() : net.sourceforge.jtds.jdbc.Driver

I think that it is because it cannot find the driver. I am going to add the path to the manifest and see if that works thank you for all the help.
