Unable to produce .class file

Hi All!
Please read the code as follows in my last question.
class BicycleDemo {
public static void main(String [] args) {
// Create two different Bicycle objects
Bicycle bike1 = new Bicycle ();
Bicycle bike2 = new Bicycle ();
// Invoke methods on these objects
bike1.changeCadence (50);
bike1.speedUp (10);
bike1.changeGear (2);
bike1.printS

stop making new threads!

    Hi,
    Most of the time error occurs on Windows plateform.
    The main reason behind this is nesting of the directories.
    Also the long directory names causes this problem.
    Thus try to keep the directory name small and the try to nest the directories to store the jsp's

  • Jbuilder produced class files?

    I have a problem converting class files produced by JBuilder IDE (v 6.0). The converter reports the following error:
    "Missing static field initializer in field XYZ", where XYZ is declared in the source as:
    final static byte XYZ = (byte)0;
    If I declare it non-zero or remove the static keyword the converter accept the produced class files. Any ideas?
    Regards,
    Jonas

    Hi all!
    I also have the same problem like Jonas', even I have compile my program both with JDK-1.3.1-b24 dan JDK-1.2.2_010, but it still produces the same error in converting phase. It comes like this:

    Yes! You are correct. I put extra space - file name should be CreateObjectDemo. No space in between bold script. So,
    Command line for compilation:

    Command line for run :
    C:\Java>java CreateObjectDemo
    Output : Width of rectOne: 100

  • Unable to Execute Class File

    Dear All,
    I am Using JDK1.3 in Microsoft Windows 2003 sever.
    I had Created a test program as follows, Which is Saved in the BIN directory Named t.Java
    class t
    public static void main (String arg[])
    {     System.out.println ("Test Prorgram ");     }
    When I compile the above Code it Compiled Successfully.
    But, When I try to execute the class
    It reports the ClassNoDefFoundException.
    It had Try the following Set Classpath = C:\jdk1.3\bin; command, still I have the same problem.
    How can I Execute the Class File.?

    Run it like this:
    java -classpath . tSome useful resource:
    Java's code conventions: [http://java.sun.com/docs/codeconv/]
    What is the classpath really: [http://en.wikipedia.org/wiki/Classpath_(Java)]
    Also, Java 1.3 is really old. I recommend to download and install Java 1.5 or 1.6.

  • Unable to compile ( not creating class file ) java file

    Hi
    I am unable to compile java file in eclipse. I am using Tomcat 5.0 and eclipse 3.0. I am able to compile the file from command prompt. I installed eclipse and did all settings including Build path ( WEB-INF\classes). But I donot see any class file getting created.

    Are you seeing errors when eclipse compiles you classes? Have you tried to build your project using; Project -> Build All? If you have and it looks like no errors are generated you may need to change your perspective. Try changing to the resource perspective to see the built class files; Window -> Open Perspective -> Other -> Resource. By default built class files end up in the bin directory of the project. i usually change my built classes directory to classes, just makes more sense to me.

  • Unable to run a .class file w/ javaw

    I created a simple application which uses swing gui.
    This application works just fine when I click the "run" button in eclipse.
    But as soon as i copy the .class file from the eclipse project folder to somewhere else and try to run it with "javaw myclass" (the filename is myclass.class) nothing happens.
    No command not found error, no nothing.
    Its like javaw finds and executes the .class and then returns to the command prompt... But I dont see any windows or any sign of my program running.
    Thx in advance

    When run with just java I get this:
    C:\>java myclass
    Exception in thread "main" java.lang.NoClassDefFoundError: myclass$1
    at myclass.<init>(myclass.java:38)
    at myclass.<init>(myclass.java:28)
    But I Eclipse it works just fine...
    What does Eclipse do that I dont?

  • Unable to read Class from META-INF/MANIFEST.MF file

    Hi,
    One of my EJB Bean is referencing a class file "test.class".
    So, I placed the test.class file under app-servers's

    But the app servers is not recognising this Class and displaying "NoClassDefFoundException".
    Any help is appreciated.

  • Unable to access jar file error !

    hello,
    i have built my netbeans project and obtained the hequalifies.jar file . unfortunately when i'm trying to run this jar file from the prompt command I'mgetting the error: unable to access jar file
    here is the command i'm typing:
    C:\Users\User\Documents\NetBeansProjects\hEqUALIFIES\dist>java -jar " C:\Users\U
    ser\Documents\NetBeansProjects\hEqUALIFIES\dist hequalifies.jar "
    anyone has any clue?
    10x!

    ok i'm gonna make it easier on you.
    i gess i found what is the problem but have no idea how to solve it.
    when i obtained the .jar file i also obtained a README.txt file in which it is written the following phrase:
    ** 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.
    I'M SORRY BUT I DID NOT UNDERSTAND WHAT IS MEANT BY: what is "the projects runtime path"?
    the content of my manifest is:
    Manifest-Version: 1.0

  • Unable to compile class for JSP

    Please can anyone help me to solve this.
    Actually,this is the condition.
    In my db,there is a table called UserPassword, which has 4
    fields(empNo,UserName,password,level). Now I want to do these things:
    When the user submits the data to create a new account via HTML form, it submits the data to the file called CreateAcc.jsp. In this file it perform some logic,here are they.
    1)To check the empNo,if it is already exist in the DB,
         if empNo =exist then display error.(record already exist)
         if empNo =notexist then do task 2).
    2)check the UserName,if it is already exist in the db,
         if UserName=exist then display error.(because it's a primary key)
         if UserName=notexist then do task 3).
    3)Create a new user account and save it to the db.
    To do these tasks,I never create a new objects for the tasks 1) and 2).
    only for task 3)create an object.
    Is it the right way?
    Here is the file CreateAcc.jsp
    <%@ page language="java" %>
    <%@ page import="core.UserAccManager" %>
    <%@ page import="data.UserPassword" %>
    <jsp:useBean id="UserAccManager" class="core.UserAccManager" scope="session"/>
    <jsp:setProperty name="UserAccManager" property="*"/>
    <jsp:useBean id="UserPassword" class="data.UserPassword" scope="session"/>
    <jsp:setProperty name="UserPassword" property="*"/>
    <%
    String nextPage ="MainForm.jsp";
    if(UserPassword.verifyEmpno()){
         if(UserPassword.verifyUsername()){
              if(UserPassword.createAcc()) nextPage ="MsgAcc.jsp";
          }else{
               nextPage="UserNameExist.jsp";
          else{
              nextPage="UserAccError.jsp";
    %>
    <jsp:forward page="<%=nextPage%>"/>The directory structure:
    UserPassword.java- F:/Project/core/data/UserPassword.java
    UserAccManager.java - F:/Project/core/UserAccManager.java
    Now both are compiling.I put the class files into the TOMCAT,as follows.
    UserAccManager.class - webapps/mySystemName/WEB-INF/classes/core/
    UserPassword.class - webapps/mySystemName/WEB-INF/classes/core/data/

    Are there any mistakes? If so tell me where is it and how to change them.Please help.

    I try it that way, but it don't compile.
    Error:core\data\UserPassword.java:package javax.servlet does not exist
    import javax.servlet.*;
    core\data\UserPassword.java:package javax.servlet.http does not exist
    import javax.servlet.http.*;
    So,I comment them only in the UserPassword.java file,and compile it again.
    Then it compile well.I goto the directory to get the .class files.
    But there is only UserPassword.class inside the data folder. There is not
    UserAccManager.class in the core folder.
    Then I try this way,I put my 2 java files in to a new folder,
    F:\SystemName\com
    When I try it that way, but it don't compile.
    javac -classpath . -d . com\*.javaError:com\UserPassword.java:package javax.servlet does not exist

    com\UserPassword.java:package javax.servlet.http does not exist

    So,I comment them only in the UserPassword.java file,and compile it again.
    Now both are compiling well.There was 2 class files.
    I put them in to the WEB-INF/classes/com directory.

  • Unable to load class from JSTL

    Hello. I am using JSTL 1.06 from Jakarta with Tomcat 4.1 on a MacOS X 10.3.9 server. I have a jsp that contains the following:
    <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
    <jsp:useBean id="validate" class="mypackage.ValidationBean" scope="request">
            <jsp:setProperty name="validate" property="*" />
    </jsp:useBean>
    <c:if test="${validate.valid == false}">
    The input is not valid.
    </c:if>In case it matters, my web.xml file starts out like this:
    <?xml version="1.0" encoding="ISO-8859-1"?>
    <!DOCTYPE web-app
        PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd">I have placed jstl.jar and standard.jar in my webapp's WEB-INF/lib directory. However, when I try to load the page, I get this error message:
    org.apache.jasper.JasperException: /myjsp.jsp(60,0) Unable to load class if
    I know that many people have asked similar questions, but in each case, the response was to put jstl.jar and standard.jar in WEB-INF/lib and make sure that you're using the proper URI for the taglib, and I think I have done those things correctly. Any help would be greatly appreciated!

    Thanks for your response! In answer to your questions:
    The JRE is 1.4.2_09. I can't use 1.5 (5.0) without upgrading the OS.
    I haven't tried it on a PC. I might be able to, but it would take me some time to set everything up.

  • ITunes 10.5.3, Unable to Load Class Data from Sync Services, Crashes Repeatedly

    Ever since iTunes 10.5.3 on my Windows 7 x64 box, I've been having serious problems keeping iTunes running:
    1)  Any time I connect my iPhone or iPad, or any time they attempt to sync over WiFi, I get the 'Unable to load class data from sync services' error.  It's worth mention that the iPhone or iPad do actually then proceed to sync correctly, and all media / data is synchronized successfully, as far as I've been able to tell.  I've reset sync history, restored the iPhone and iPad, manually moved the SyncServices directory, set both the iPhone and iPad up as new, completely uninstalled iTunes and the mobile device software, re-installed, and *nothing* I do fixes this issue or even seems to impact it.  Uninstalling iTunes 10.5.3 and reinstalling iTunes 10.5.2 resolves this error.
    2)  iTunes 10.5.3 has serious crashing problems on my machine, though I've searched through forums and found a lot of other people with the problem.  In my case, sporadically as iTunes access the iTunes store (for example, I can always make it happen by subscribing to the Diggnation podcast and telling it to refresh the podcast), I get a full application crash which generates the following event in the event log:
    Faulting application name: iTunes.exe, version: 10.5.3.3, time stamp: 0x4f14cc3d
    Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319

    Faulting module path: C:\Windows\syswow64\KERNELBASE.dll
    Report Id: ecc77400-537a-11e1-b809-00248c196007
    Again, uninstalling iTunes 10.5.3 and re-installing iTunes 10.5.2 fixes this issue as well, but I really shouldn't have to do that.  Is there any actual solution to these problems other than dowgrading to an older version?
    Yes, I'm running current malware protection (and my system is clean) and yes, I've already checked any other obvious culprits to make sure I don't just have a corrupt library or file somewhere that's causing it.  My Windows 7 install is completely up to date from a Windows Update perspective and also from a driver perspective (even including the motherboard and chipset drivers).  I made sure to do a system file integrity check (sfc /scannow) and it confirmed my install of Windows isn't suspect, but beyond all that I was able to reproduce these failures on a completely separate machine running Windows 7 x64, without any of my media library or data on it -- iTunes 10.5.3 just seems to be bad news on Windows 7 x64 for me, even though I know there are definitely people are using it successfully.  I don't get any other application crashes for any other applications, and I've never had an issue like this with any previous version of iTunes...
    Last but not least, in case it matters, I'm running iOS 5.0.1 on both the iPhone4 and the iPad2.  The iPhone4 is the GSM AT&T model and the iPad2 is the CDMA Verizon model.

    OK, I've given up.  Uninstalled iTunes 10.5.3 permanently.  It's a shame, 10.5.2 works perfectly but 10.5.3 is a complete and total cluster for me.
    Anyone with the same problems who hasn't done this already, just uninstall iTunes and the Apple Mobile Device Service in your Add/Remove Programs, then re-install iTunes 10.5.2.  You won't lose your library or any settings or apps, it will just go back to working again.
    I wish Apple would acknowledge this so that I'd at least know it would be fixed in the future.
