Weblogic not finding javax.naming classes when instantiating bean

Hello,
          I am developing a JSP which contains a JavaBean.
          This bean is a wrapper for a session EJB, the getProperty() methods in
          the bean call methods on the EJB's remote interface.
          I have tested this bean as a stand alone application by adding a
          main(String[] args) method to it and it works.
          However, when adding the bean to the JSP, the JSP does not show in the
          browser, I get a n internal server error 500 instead.
          It seems that Weblogic is not finding the javax.naming.NamingException
          class when instantiating the bean.
          When looking at the weblogic log, I see the following stack trace:
          Fri Aug 18 15:12:06 EDT 2000:<E> <ServletContext-General> Servlet failed
          with Exception

          yes, weblogicaux.jar is definitely in the weblogic.class.path. i've even tried starting the server from the command line, declaring the classes there. my "trade.xml" document has the URI set as "http://localhost:7001/BizTalkServer". when i enter this on the "BizClient.jsp" form, i get the error discussed below. however, if i enter "http://localhost:7001", even though this is not the explicit location of the BizTalk server, the server returns:
          Thank you! Your trade has been recieved. A BizTalk document has been sent to http://localhost:7001/ with the following information: etc...............
          So there appears to be something wrong with the "/BizTalkServer" setup on my machine. Any ideas?

  • "Could not find the main class" when running a jar

    Hi, I'm trying to create and run a jar from my application, but I can't figure out how to properly set an entry-point. Looking at the Java Tutorials http://java.sun.com/docs/books/tutorial/deployment/jar/index.html I still can't get it to work.
    I have a directory myApp, which contains a directory images and some class files, including mainClass.class. I also have a manifest Manifest.txt in the directory myApp with the following line:
    Main-Class: mainClass.class
    + one empty line
    I create a jar successfully, while inside the myApp directory, with the following command:
    jar cfm myApp.jar Manifest.txt *.class images\*.*
    I then proceed to run the jar with the following command:
    java -jar myApp.jar
    and receive the following error:
    Exception in thread "main" java.lang.NoClassDefFoundError: myApp/class
    My completely uneducated guess is that there is something wrong with my manifest. The tutorial says that the line should be:
    Main-Class: MyPackage.MyClass
    I'm assuming that I get the error because I didn't specify a package, which I didn't do because I didn't know what to put there. Do I even have a package?
    Can anyone tell me what I've done wrong? thanks.

    One problem is you are specifying a file name instead of a class name. It probably should beMain-Class: mainClassA good test is to run your app before jaring it - if you run it with "java mainClass" then the Main-Class attribute must be mainClass.
    Also class naming conventions say that class names should start with a capital letter - MainClass for example. It is just a convention, but it is easier to get help when you follow conventions.

  • Can not find javax.ejb.CreateException when lookup and create EJB instance.

    Hi,
        I installed SAP CE 7.2 and NWDS 7.2. When i call create() of EJB's home interface from JAVA stand alone app to create EJB instance, the complier state that it need  'javax.ejb.CreateException'. How can i find the jar that contain 'javax.ejb.CreateException' to solve this problem?
    Thank a lot,

  • Can not start WebLogic in Eclipse. Error: "Could not find the main class."

    I have installed Eclipse 2.0 and WebLogic Server 6.1. and the WebLogc plug in from GENUITEC (and jdk1.3.1_04, on Win2K Server). After I have done the configuration, the WebLogic start/stop buttons are integried into the Eclipse Toolbar, but when I click on the start button to start Weblogic, it pops up a dialog box "Java Virtual Machine Launcher" with message: "Could not find the main class. Program will exit!"
    Starting WebLogc Server from the Start panel works fine.
    Does any one have seen this before or have a suggestion what I should do?
    Many many thanks in advance.
    Huan

    Weblogic must be started with a full JDK; otherwise
    JSPs and dynamic EJB stubs could not be deployed. The
    error message
    indicates you are attempting to use a JRE. Configure
    Eclipse JRE to point to a JDK. The product
    documentation will help you with this process. It does not work for me. :-(
    I have tried JDK 1.3.1 and 1.4.1: same result: I get a "Could not find the main class: Program will exit"

  • Execute jar file: "could not find the main class" program will terminate

    Hey,
    I am new to Java. I have started to make a small java program which supposed to help me at my studies to lean the Dominic Memory System. I have used the latest version of Netbeans 5.5.1 to build my program in. I have two problems which I cannot figure out how to solve, please help me.
    The first problem is that the java script I have made works when I compile it in Netbeans, but when I create a Jar file it does not work. I receive a pop up message in windows ?could not find the main class program will terminate? when I execute the jar file.
    The second problem I have is that I need to compare the strings generated by the "numbers" and "TIP" and if the numbers is not identical the numbers in the ?Center? JPanel should be highlighted as red.
    If anyone would like to clean up the code I would be pleased. I have copied quite a lot from anyone because of my one lack of knowledge.

  • Could not find the main class (with every jar)

    This isn't a developer question. I get the error Could not find the main class with every jar I try to open (for example the jar downloaded from https://gjar.dev.java.net/ gives the same problems - and I don't think there is something wrong with that JAR). It isn't a problem with the jar or MANIFEST because the same jar works fine on my laptop. So there is something wrong with my JRE installation, but what?
    I tried to remove and reinstall the JRE 6 Update 18 but that didn't work. When I run the JAR with command line java -jar "file.jar" it works fine, but if I dubbelclick on it I get the error message (and it's irritating me).
    I'm a bit desperate so I hope that someone here can help me ;)

    Any Ideas? I did a search on google, and looks like others have had this problem but found no answer.

    There could be several reasons for getting this "Could not find main class" error message. From your stack trace it looks like the class javax/media/ControllerListener is not in your class path. Make sure your manifest file has a line like this:
    Class-Path: pathToTheJarFileWithControllerListenerClass.jar otherJars.jar
    This error message is also generated whenever any static initialization errors out giving the misleading error message implying that there is something wrong with the main class. Prior to starting your main class, static initialization of any static variables takes place. In my case, I was initializing a resource bundle, and forgot to include the property file in my building of the jar file. Well this failed of course and the generic error message appeared. It took many long hours to figure out it didn't have anything to do with the manifest file or the main class itself.

  • [Jar Executable] Could not find the main class. Progam will exit.

    Hello,
    I am a French person. Excuse me for my English who is not perfect.
    I seek to create an achievable "jar". I followed the instructions given in the url http://java.developpez.com/faq/java/?page=execution#creationJar, and on the site of Sun.
    I have today only one class which I posed in a specific repertory "Class".
    Appli
    |__Class
    |__Src
    |__META-INFThe contents of my "Manifest" is stored in repertory META-INF with the name "Commission2007.MF" and its contents are as follows:
    Manifest-Version: 1.0
    Created-By: 1.5.0 (Sun Microsystems Inc.)
    Main-Class: Commission2007
    .I've left the space line at the end of the file.
    Here the result of execution of my order "jar":
    C:\#Java Dev\2007_Commissionnements>jar cvfm Commission2007.jar META-INF/Commission2007.MF -C Class/ .
    manifest ajout�
    ajout : Class/./(entr�e = 0) (sortie = 0)(0% stock�)
    ajout : Class/./Commission2007.class(entr�e = 9060) (sortie = 4547)(49% compress�s)I controlled the assignment of the extension "jar" in "Working station = > Tools = > Files Option = > Files Type = > .jar Selection = > Advance =
    Open = > Change = >" C:\Program Files\Java\jre1.6.0\bin\javaw.exe "- gravel bank" %1 "% *". Thus not of problem on this side there!When I double click on the file "jar" lately created, I have the error message according to: "Could not find the main class. Progam will exit. " I do not understand the reason of this error. I consulted all the subjects on the treating Net of this subject but without result. I thus call upon you.
    Perhaps that the cause is in my code which however functions perfectly when I carry out it with the order: "Commission2007 java". The class "hand" is quite present to see the code below. You can find the totality of my code on the bond http://www.developpez.net/forums/showpost.php?p=1870361&postcount=74

    }I thank you in advance for your assistance.
    Cordially, Gilles.

    Salut,
    It has been my experience that it is never a good idea to name your .MF file anything else other than MANIFEST.MF.
    Try naming your .MF file MANIFEST.MF and rebuild your JAR.
    Bon chance.

    I was able to resolve this issue by performing following.
    1. Go to the location where sqldeveloperW.exe is being executed from.
    2. You will find a file sqldeveloper.conf in that location. Edit this file and change the value of IncludeConfFile to point to actual place. For me following were old and new values.
    OLD (Wrong) : IncludeConfFile ../../jdev/bin/ide.conf
    NEW (Correct) : IncludeConfFile ../../ide/bin/ide.conf
    After making above change in the sqldeveloper.conf file. Save and close it. Restart SQLDeveloper. You will not get the error anymore.
    Thanks

  • Executable JAR file: Could not find the main class.

    Hello,
    I have a problem with making an executable JAR file.
    I have written a JAVA program that consists of five different classes of which User.java is the main class and I have saved a text document with Main-Class: User and a blank line after that.
    If I try:
    jar cmf MainClass.txt User.jar User.class Beheerder.class Operator.class Manager.class MaakVisueelSchema.class
    it makes a executable jar file which actually works! :)
    But when the Operator class trys to open the MaakVisueelSchema class the screen stays blank.
    I can run MaakVisueelSchema with java MaakVisueelSchema.
    So I tried to make an executable JAR that consists only of MaakVisueelSchema, the same way as I did for User:
    Main-Class: MaakVisueelSchema
    jar cmf MainClass.txt MaakVisueelSchema.jar MaakVisueelSchema.class
    Then I get the error message:
    Could not find the main class. Program will exit.
    from the Java Virtual Machine Launcher.
    The big difference between MaakVisueelSchema and the other classes is that MaakVisueelSchema contains a PaintComponent method and an ComponentListener. Is it possible that one of those creates the error?
    Can anyone help me with this problem?
    Thanks in advance!
    Bye!

    Yes,
    I tried:
    jar xvf MaakVisueelSchema.jar
    and it returns:
    META-INF/
    META-INF/MANIFEST.MF
    MaakVisueelSchema.classN/G. You need to manually create a manifest file in a text editor, have it point to your main class, and enter it in your jar command as an argument.

    Where is SearchExcel.class?Excellent question, though I think I spotted a problem with the cp supplied.
    Note the documentation for -cp state (in part)
    For example, if directory foo contains a.jar and b.JAR, then the class path element foo/* is expanded to a A.jar:b.JAR, except that the order of jar files is unspecified.So instead of this..
    java -cp /tmp/MyJava/excelapi:/app/jdk/1.6.0_16/jre/lib:/app/jdk/1.6.0_16/lib SearchExcel..try this..
    java -cp /tmp/MyJava/excelapi/*:/app/jdk/1.6.0_16/jre/lib:/app/jdk/1.6.0_16/lib SearchExcelNotes:
    1) Adding the JRE classes to the classpath should not be necessary, but I left the rest of the cp unaltered to highlight the one specific difference I am suggesting.
    2) When posting code, code snippets, HTML/XML or input/output, please use the code tags. The code tags help retain the indentation and formatting of the sample. To use them, select the sample text and click the CODE button.
    If that still fails, tell us more specifically where the SearchExcel class is by copy/pasting the output (within code tags) of the command..
    prompt>jar -tvf mysearchexcel.jarWhere, of course, you replace 'mysearchexcel.jar' with the actual Jar name it is supposed to be located in.
    Edit 1:

    The structure of my project in Eclipse is src/project/files.java and in jar file is src/files.java bin/class.java Dati/ and META-INF/.That's wrong. You don't need the .java files in the jar (but you can have them, if you want, they are just not used by Java).
    And each .class file must be in a directory that reflects its package. So in your example ProjectGUI.class must be in the directory projectRFID/ inside the .jar file.

    hi,
    I create one java project. for this I am using netbeans 5.
    I try to run the project jar file stff.jar. When run using "java -jar stff.jar " , it throws error "could not find the main class. program will exit".
    I am extracting this jar file, in manifest, main class is set.
    i.e, in manifest, Main-Class: ems.emsFrame.
    ems is my folder ,inside it main class kept.
    here, emsFrame is my main class where " public static void main (String args[])" is located.
    I am also, set the class path for that class folder(ems) and run.
    The same error ("could not find the main class. program will exit") occured.
    Why this error occured.
    also,I am uninstall the jdk and reinstall .
    whats my problem.
    bye

    yes sir.
    In projects, inside it, in Libraries ,the SNMPInquisitor.jar is located.
    inside that jar, snmp package is located.
    but, when build and run, there is no problem sir.
    Only when i try to run the stff.jar file (java -jar stff.jar), that time only the exception thrown.
    when I double click that jar, it show, "could not find the main class. program will exit". But, I am adding the main class in manifest. when i open manifest.mf, it show, Main-Class: ems.emsFrame.

    "Could not find the main class. Program will exit."
    If I compile and run the source myself it works fine, so it must be a setting in Eclipse somewhere...
    It doesn't work, even when I put the class in the default package...
    It must be something very stupid, but I can't seem to find out what the problem is :(
