noclassdeffounderror

I have unpacked my jdk in /usr/java/. and I put CLASSPATH, PATH, JAVA_HOME into /etc/profile like below. export JAVA_HOME=/usr/java/jdk1.7.0_21 export PATH=$PATH:$JAVA_HOME/bin export CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar And when I compile some java file in /usr/java/jdk1.0.7_21/bin, it works. But when I am doing same thing on other folder, it doesn't. It displays NoClassDefFoundError. So I have checked ClASSPATH, PATH, JAVA_HOME via echo. It shows like below. [root@localhost a]# echo $JAVA_HOME /usr/java/jdk1.7.0_21 [root@localhost a]# echo $PATH /usr/lib64/qt-3.3/bin:

I am using sitemesh to decorate the pages. I am using a JSP page for this. The page worked fine until I used the <c:if> conditional tag. I have the jstl-impl-1.2.jar & sitemesh-3.0-alpha-1.jar files in the WEB-INF/lib folder. I have following tag library declarations in the jsp page: <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql" %> I am using tomcat 7.0 with java 6.

Possible Duplicate: NoClassDefFoundError - Eclipse and Android I'm seeing this question is getting asked a lot in many different contexts. Perhaps we can set some strategies for locating and fixing it? I'm noobish myself so all I can contribute are horror stories and questions, sorry... It seems this is thrown when a class is visible at compile time but not at run time... how can this happen? In my case I am developing an app that uses the Google APIs, in Eclipse, for the Android platform. I've configured the Project Properties / Java Build Path / Libraries to include the gdata .jars and all

I've looked through many of the existing threads about this error, but still no luck. I'm not even trying to package a jar or use any third-party packaging tools. I'm simply running from within Eclipse (works great) and then trying to run the exact same app from the command line, in the same location it's built to (getting this error). My goal is to be able to zip up the bin folder and send it off to be run by someone else via a command line script. Some details: It's a command-line app and I'm using the commons-lang-2.4.jar for string utilities. That is the file that cannot be located

I'm new in JasperReports and I want to integrate a JasperReports into my Java program, so when I click print button the program will show the report. But I get a NoClassDefFoundError when I click the button. Code JButton btnReport= new JButton("Report"); btnReport.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent arg0) { try{ String fileName= "src/learnReport/Leaf_Grey.jasper"; Connection con = connect.getConnect(); File file = new File(NameFile); JasperReport jasperReport = (JasperReport) JRLoader.loadObject(file); JasperPrint jasperPrint = JasperFillManager

I've installed Eclipse for android and that works okay. When I try to start a java-file I got the following error: Error occurred during initialization of VM java/lang/NoClassDefFoundError: java/lang/ref/FinalReference After some research I know it was something with buildpass but after trying I didn't got it to work. I removed it all (Eclipse, Java, Android) and reinstall everything but with the same disapointing result. Could somebody explain to me what to do because what I tried from the internet didn't work for me. Find Running configurations -> java application In the new configuration's
