Running jar files issue

On a Windows xp machine, I can run the jar file from command line. But unable to run by double clicking it
I did check ftype jarfile on command line and I did get the correct values. I did compare this value against the value on a machine where jar file works fine.
I did assoc .jar=jarfile on command line. Still it does not work. java6 is my environment.

The screen comes and goes so quick. The error is it can't find the main class. But the same jar file runs from command line
without any issue.

  • Error messege when run jar file

    when i run jar file of my project give me that error(Fatel exception occured.program will exist)
    what is the reason of that error

    "can't get that path". Sounds like requisite classes aren't on the classpath.
    Please paste the ENTIRE error message that it's producing into your next reply. You have probably forgotten to include necessary classes - perhaps a JDBC driver - in your JAR file.

  • Running Jar Files created in Sun Java Studio

    Hi everyone,
    I am still trying to explore the functionalities (especially as regards deployment issues) of this robust IDE. However I do have a problem. I have developed a very basic program that connects to a database (MSSQL) using Java Studio 8. However after building the jar file, if I try to execute the jar file it gives me this message
    java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver.....
    But all goes well within the IDE and it runs well if I use my notepad or vi editor,compile it from the command line and execute the generated class file. The classpath have been set for all the necessary jdbc jar files.
    Any Help Will Be Appreciated

    1. Sun Java Studio Enterprise 8 is based on NetBeans 4.1 which does not provide direct support for packing an application. One alternative you may want to consider is to use NetBeans 5.0 (http://www.netbeans.info/downloads/download.php?type=5.0) or JSE 8.1 which is based on NB5.0 and which is now in beta (http://developers.sun.com/prodtech/javatools/jsenterprise/downloads/index.jsp).
    You may want to refer to http://www.netbeans.org/kb/articles/javase-deploy.html for packing and deploying a standalone application is NB5.0 or JSE8.1.
    2. Using JSE8, you may want to try copying all the library jars (including database drivers) used by your application to your projects dist directory manually and then package them all into one jar.
    3. You should not have to know the exact location of the jdbc jar on the client machine. How are you instantiating the driver in your code? Are you using 'Class.forName()'? If so, java should be able to pick up the driver from the classpath. (Pl. ref to http://forum.sun.com/jive/thread.jspa?forumID=122&threadID=62696, which may be of help).

  • Could not read Log4j configuration file when I run jar file

    Hi,
    I'm using Log4J in my application..
    I configure the log4j, as follows;
    PropertyConfigurator.configure("properties/logging.properties");and then go on to use it.
    The .properties is in the root when I jar my source. I use Ant to Jar the file. It all works good when I run the jar file from ant.
    The problem is when I run the jar file by double clicking on it, I get an error
    " Could not read configuration file [properties/logging.properties]."
    I tried the following options;
    PropertyConfigurator.configure("/logging.properties");
    PropertyConfigurator.configure("./logging.properties");
    PropertyConfigurator.configure("../logging.properties");But in all cases, I get corresponding errors on running the jar file through Ant:
    log4j:ERROR Could not read configuration file [logging.properties].
    log4j:ERROR Could not read configuration file [./logging.properties].
    log4j:ERROR Could not read configuration file [../logging.properties].
    I want to be able to run the Jar by double clicking on it or through Ant.. Would any one know how to fix this issue so that I can use both methods..

    Keep your properties file inside the root folder of your application.It is working fine

  • Oracle 11g application won't start sometimes(jar files issue)

    Hello,
    The issue we experience is that now and then, our forms 11g application
    won't start.
    So it can be the case that, for example, the application can be started
    succesfully 5 times in a row, but the 6th and 7th time, it won't start
    anymore. But when we relaunch it for the 8th time, it launches perfectly.
    When the application isn't starting, a new window is opened having a yellow triangle
    with an exclamation mark on the top right corner.
    After a long period, we suddely discovered that it had something to do with ".jar" files.
    Because when we clear the "java jar cache" on the client machine
    (start -> control panel -> java -> "general" tab -> "view..." button -> select all the files and click on the
    cross(remove selected sources) ), the application succesfully starts for about 10 times in a row.
    But the first time we start the application(after clearing the cache), it takes much longer, because the application
    is downloading the .jar files again. (java logo appears with a progress bar)
    But clearing the cache every time before starting the application can't be a decent solution we think.
    When we enable all java debugging info in the console, we received the error below 2 times when launching a application session that refused to start:
    java.security.AccessControlException: access denied (java.lang.RuntimePermission accessClassInPackage.sun.awt)

    Anyone having a clue ?
    thanks in advance !

    Sorry, I meant WEB-INF\lib in the WAR file inside my EAR.
    I put all the jar files in the WEB-INF\lib of the WAR file but it still does not work. I have to specify them in the classpaths and put the jar files in the domains\domain\lib directory
    I thought if you put it in the WEB-INF\lib then you don't have to put them in the classpath.
    Am I right?

  • Instant Client 10 Jar File Issue

    I'm following the instructions to install Instant Client 10, but the Jar files won't run on Windows.
    classes12 and ojdbc14 both give me "Failed to load Main-Class manifest attribute....", and when I check the manifest file, this info is in fact missing, along with the classpath.
    The instructions don't indicate anything about this. I'm wondering if I'm missing something here. I have the newest Java installed.

    What exactly are you trying to do? Install Client or execute classes?
    Once you instal your client it is so, if there were no problems on the installation there are no issues to solve.
    Which client did you install? On the Oracle Universal Installer there are several kinds of clients, regular and instant client.
    What do you need this client for?
    Once you have installed, I figure out you are trying to do some java programming, aren't you? How are you trying to use those classes?

  • Unable to run jar file without lib folder containing swing-layout-1.0.jar

    I have done my project through NetBeans 5.0. Eventhough I have copied my lib foloder containing swing-layout-1.0.jar inside my project.jar, I am still unable to run my project.jar in other systems, it is creating an error as Could not find the main class. Program will exit. But if I copy the lib foloder containing swing-layout-1.0.jar in the same path as the project.jar, then my project.jar is running.
    But I want to give only the project.jar for other users and not also lib foloder containing swing-layout-1.0.jar each time.
    Could someone please help me with this.

    When you develop GUI applications using the Netbeans you may endup using netbeans specific jar files in your auto generated code.
    And when you build jar files with netbeans it copy the third party jar files used in a application in to a lib folder in the same directory as the jar file of your project. And then set a class path entry to those jar files in your project jar file's manifest file.
    So if you want to redistribute the package you have to redistribute your jar file and every thing in the lib folder in with the same directory structure.
    If you want to change the structure you will have to change the class path to suit the new structure.

  • Jar file issue. EXCEPTION: java.lang.UnsatisfiedLinkError

    Hey all,
    i'm writing an application that connects to Oracles SCM. I use a lot of the oracle SCM library. Anyway, my application running in oracles jDeveloper works just fine. However when i deploy it to an executable jar file i get the above exception. In the deployment settings i have tried both using the dependency analyzer and including all content. I have selected all libraries that are used in running it within jdeveloper for the deployment. I have posted to the SCM forumn but noone there has any ideas so just wondering if its a problem with jdeveloper or if its just something stupid i've done.
    find the below the full exception im getting when i run the executable jar file. i'd appreciate any ideas/suggestions anyone may have
    cheers

    I have tried putting my executable jar in the same folder as
    this dll and including the dll in my path but both to no avail.Again: you mix binary code and JVM byte code. They are loaded
    differently and located differently. classpath means nothing for the binary code.
    "The Win32 VM uses a search path that includes the current directory for the process or one of the directories listed in the PATH environment variable"
    The DLL may be either in the folder where the application (the JRE/JDK) runs, that is where java.exe is, or some other directory on the system PATH (according to the PATH system variable).

    This is happening for multiple projects now, though I don't remember it happening before. What am I doing wrong? Why is this happening? How can I fix it? Thank you for any insights...

    Oh, I forgot to mention, all the NetBeans samples work, just not apps that I create. This is very frustrating!

  • How to create a running jar-file

    I created a "Java Class Library" project including 20 class files in several packages and some libraries.
    Because I would like to start the project from the console, I added the main-class property (right-click project, Properties, Run). Then I cleaned and built the project and tried to start it with the following command:
    java -jar PROJECTNAME.jarBut it won't work, because the archive is not complete: MANIFEST.MF lacks the main-class and all involved libraries.
    I managed to add the main-class attribute manually, but adding all library references seems to be very error-prone.
    So does anyone know if I did something wrong or if this is a bug of Creator?
    Regards,
    Felix

    The main intent of this project type is to provide a libraray which normally wouldn't run with a "main". I suggest you use NetBeans to create a "Java Application" project. Here's what is in the README.txt file produced with the jar. This looks like what you're looking to do. So you can create the Jar in NetBeans then if you want to use it in Java Studio Creator, you can add it to the Creator project. Also, if you caught the news at JavaOne, we are providing Creator features for a pack that will run in NetBeans so you won't have to switch back and forth between the tools. Keep an eye on the NetBeans and Creator web sites for more info.
    Thanks!

    README.txt
    ========================
    BUILD OUTPUT DESCRIPTION
    ========================
    When you build an Java application project that has a main class, the IDE
    automatically copies all of the JAR
    files on the projects classpath to your projects dist/lib folder. The IDE
    also adds each of the JAR files to the Class-Path element in the application
    JAR files manifest file (MANIFEST.MF).
    To run the project from the command line, go to the dist folder and
    type the following:
    java -jar "JavaApplication3.jar"
    To distribute this project, zip up the dist folder (including the lib folder)
    and distribute the ZIP file.
    Notes:
    * If two JAR files on the project classpath have the same name, only the first
    JAR file is copied to the lib folder.
    * If the classpath contains a folder of classes or resources, none of the
    classpath elements are copied to the dist folder.
    * If a library on the projects classpath also has a Class-Path element
    specified in the manifest,the content of the Class-Path element has to be on
    the projects runtime path.
    * To set a main class in a standard Java project, right-click the project node
    in the Projects window and choose Properties. Then click Run and enter the
    class name in the Main Class field. Alternatively, you can manually type the
    class name in the manifest Main-Class element.
