Jar file of the Bean

Why to make the .jar file of the each bean?
is it necessary?
I am new to EJB.....
expecting kind response.
Thanks.

Do you mean, "Why make a *.jar file for each bean?" (sorry, but your question seems like master Yoda's speech)
If that is your question, you don't need to put each bean in a separate jar but group all the ejb in a single jar (all the beans that logically belong to each other -- a module that is).

    Hi,
    projects are a design time functionality. So what is the use case? I it is a Java object stored in the JAR file then you would configure this JAR file in the ViewController project library section (project properties)

  • Do I need to add to add a new jar file to the WLS ?

    I am new to java development and would like to know if I were to use a new jar
    file developed by another party in my EJB development, do I need to have this
    jar file available in WLS when I deploy the EJB to it ?
    I think this is not required but just need a confirmation.
    Thanks

    Hi,
    I take this to mean you are using java classes from the 3rd party jar in your
    EJB bean class. If that is the case, then you need the jar file in your classpath
    when you compile the EJB classes.
    Also, you will need the jar file to be in the classpath when the EJB is used.
    You can do this in a variety of ways. If the 3rd party jar is going to change
    infrequently, then you can put it in the system CLASSPATH in your startWebLogic
    script. Or you can add all the classes of the jar file in the root level of the
    EJB (Yuck!!).
    Perhaps the best answer is to create an enterprise application (EAR). Then you
    place the jar file in the root level of the EAR. In the META-INF\MANIFEST.MF
    file of the EJB place
    Class-Path: filename.jar
    Then when you build the .ear file use:
    jar -cvfm ..\commuterLog.jar META-INF\MANIFEST.MF *
    hope this helps,

  • How do I update a file in an Applet's JAR file from the Applet code

    Here's my problem.
    My applet is using a serializable history data in which I am storing in the applet's JAR file. When I run the applet, I read the file with "getResourceAsStream()" and run my program with that hist data. When my applet is closed, I need to update this file from my Applet's code and I dumfounded about how to do that.
    Is there any way to update a file in the Applet's JAR file through the Java Applet code? (i.e. OutputStream?).
    Would appreciate any advice people have.

    Just place a copy of the file on the local hard disk and update that. When you start the Applet you try to read from the hard disk. If the file exists then no problem otherwise copy it from the jar to the hard disk.

  • How do I add a jar file into the build path of the compiler?

    Hey,
    I'm trying to import a jar file into the build path of the compilation process, but it does not find the packages or the classes that are in it.
    I think I don't add it right...
              ArrayList<String> options=new ArrayList<String>();
              options.add("-d");
              options.add(targetDirectory);
              options.add("-classpath");
              for(String str:includeDirectory)
                   options.add(str);
              if (!compiler.getTask(writer, fileManager, diagnostics, options, classes, compilationUnits).call());
                    ....and I've tried this way:
         public void setTargetDirectory(String targetDirectory) {
              this.targetDirectory = "-d " + targetDirectory;
         private void compile(Iterable<? extends JavaFileObject> compilationUnits) throws Exception {
              ArrayList<String> options = new ArrayList<String>();
              options.add(targetDirectory);
              String classPath="-cp ";// tried this also with "-classpath"
              for (String str : includeDirectory)
                   classPath+=str+":";
              options.add(classPath);
         if (!compiler.getTask(writer, fileManager, diagnostics, options, classes, compilationUnits).call())
              // throw new Exception("Compilation Error");
         }Thanks in advance,

    Thank you for your reply,
    Q: Are there .class files in that directory in that jar file? (the compiler doesn't ( can't )) look for directories, it can just look for specific files , and scan to get a list of all files matching certain criteria. So if there are no class files, it will say the package doesn't exist, even if there is a directory, possibly containing other files.yes there are class files in the jar, the tree structure:
    j2MeDataChunkGenerator_Plugin\(lots of class files)
    META-INF\manifest.mf
    and thats it.
    , your code will only work on windows because other platforms use a different path separator. You should use java.io.File.pathSeparator not explicit ';" when building your classpath. (this is unrelated to your problem, but you should correct it)will do, thanks.
    Q: Is that error in your post formatted by your own diagnostics? (we could possibly help you better if we didn't have to guess!!)I would not post my own error code, this text is generated by the compiler diagnostic.
    {code}
         System.err.println(" Error details: " + diagnostic.getMessage(null));
    {code}
    Q: Is line 3 of ImageCroper_Editor.java (sic) an import statement? (we could possibly help you better if we didn't have to guess!!)it is an import error... didn't the error message stated that it is an import problem? wired, I'm sure before it did. anyway it is an import error.
    Also you don't show us what the variable includeDirectory is in terms of type, and contents, that might be helpful. (we could possibly help you better if we didn't have to guess!!)It has only one String object: "D:\%Important Documents\WorkSpaces\PacMan\ApplicationManager\Plug-in\Data Chunk Designer.jar"
    the last file on the classpath list.
    Q: Have you proven this? that i did post, in this long line of text.
    Q: Is the compiler finding other classes (in other packages) in that same jar file?No. all the class files are in the jar, they all have entries that start with "j2MeDataChunkGenerator_Plugin\*.class", and since I get 47 errors I guess it does not load any other class.
    thank you for you comments, the problem with having these errors, is that I can't even get a piece of information where this error is coming from, only that it is an import loading error package not found, what does that mean? that the jar was not loaded in compilation(no error about this), that the jar is corrupted(no error about this), that the path is incorrect(it is correct I made sure), that there is no such package in the jar(There is), that the compiler does not load the package(does it even do that?), really I can't even guess why this happens, I've been at this on and of all day today, really annoying.
    Thanks,
    Adam.

  • How to refer a .jar file in the code.

    How to refer a .jar file in the code.
    I want to use a library dnsjava.jar, which I download from the internet. I want to know how to refer it
         If I am compiling the code on Solaris
         If I compiling the code on windows using eclipse.
    I added the following line in my code to refer to this library. But it always complains of not found the class
    import org.xbill.DNS.*;
    I tried the following to add this library but did not work
    On eclipse/windows: Went to window-> preferences -> BuildPath _> class path Variable.
    On Solaris: Could not add this library /opt/java_reference/v1.6.0_04/jre/lib. Although I am logged in as root, but not able to add the library there. Complains of Permission denied.

    Set the classpath option when compiling.
    javac -classpath /path/to/lib/dnsjava.jar YourProgram.java
    I don't use Eclipse, but it probably has a library list on your project preferences. Add it there.

  • JWS requests jar files at the wrong place

    Hi all,
    I created JWS project with netbeans, and by deafult, NB places all required jar files in the "lib" folder. NB also created jnlp file with correct paths to required files. It looks like this
    <update check="always" policy="always"/>
    <resources>
         <jar download="eager" href="main.jar" main="true"/>
         <jar download="eager" href="lib/required.jar" main="false"/>
    </resources> Now, when app is started, required.jar is correctly located at lib folder and application works, but from that moment on, JWS makes hundreds of request for "${codebase}/required.jar" (obviously wrong place) and gets 404 responses. It keeps making these requests as long as app is running and this slows down application significantly.
    My temp workaround was to move required.jar to codebase root and problem is gone, but i still find it weird. I guess this may explain some complaints about slow JWS.
    Is this a bug? Am I doing something wrong? Is there anything I can check?
    Thanks!

  • Which jar file has the class TaskFlowBindingAttributes?

    Hi,
    I'm using JDeveloper version - 11.1.1.6
    I want to know which jar file consists the TaskFlowBindingAttributes class?
    I looked into following location - JDEV_HOME\oracle_common\modules\oracle.adf.controller_11.1.1\ and didn't find this class in jar files located here. (adf-controller.jar, adf-controller-api.jar and adf-controller-rt-common.jar)
    Any inputs would be helpful.
    Thanks
    Ravi

    Hi,
    I found it in ADF 11g R2 documentation - http://docs.oracle.com/cd/E24382_01/web.1112/e16182/taskflows_regions.htm#insertedID10
    I guess this is 11g R2 feature.
    I have a requirement to display the multiple regions dynamically. This feature suits my requirement perfectly, but unfortunately it is not available in 11g R1.
    Can we achieve the similar functionality in 11g R1 through other means?
    Thanks

  • Can a unsigned jar file access the tmpdir (java.io.tmpdir)?

    Hello, according to the JNLP tutor, a signed jar file can access the local file system, but a unsigned one can not. My question is, can a unsigned jar file access the temp directory (the system property java.io.tmpdir)? I think the temp directory should be accessible even though it is part of the local file system.
    Thanks,
    LyLi

    no - unsigned application has no read/write access to the temp dir, but you can use the jnlp api to read and write files with the users permssion.
    see: http://java.sun.com/javase/6/docs/jre/api/javaws/jnlp/index.html for FileOpenService, FileSaveService, and ExtendedService.

  • 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.

Maybe you are looking for
