How to resolve NoClassDefFoundError: org/apache/log4j/Logger in linux

Question

This is my simple program

First of all , log4j is present under WEB-INF/lib directory .

package com.util;
import org.apache.log4j.Logger;
public class TestCron {
    static Logger logger = Logger.getLogger(TestCron.class);
    public static void main(String[] args) {
        System.out.println("sysout sattement for sample ");
        logger.error("This should appear inside dealer logs");
    }
}

I have got a script which I am trying to run manually in Linux.

 #!/bin/bash 
cd /usr/local/tomcat7/webapps/Test/WEB-INF/classes/
JAVA_HOME=/opt/jdk1.7.0_67 
CLASSPATH=/usr/local/tomcat7/webapps/Test/WEB-INF/lib/*: .
$JAVA_HOME/bin/java -Dlogfile=/root/MyAppLogs/dealer/app.log -cp . $CLASSPATH com.util.TestCron

I am getting the following error

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logger

Could you please tell me how to resolve this issue ?

Edited part

#!/bin/bash 
cd /usr/local/tomcat7/webapps/OMS/WEB-INF/classes/
JAVA_HOME=/opt/jdk1.7.0_67 
CLASSPATH=/usr/local/tomcat7/webapps/OMS/WEB-INF/lib/*: .
$JAVA_HOME/bin/java -Dlogfile=/root/OrientAppLogs/dealer/app.log -cp .:$CLASSPATH com.util.TestCron

it seems, your $classpath is not included into -cp parameter value because it uses a semicolon as separator. it could look like -cp .;$CLASSPATH or similar — Stanislav

did you do it as $JAVA_HOME/bin/java -Dlogfile=/root/MyAppLogs/dealer/app.log -cp .;$CLASSPATH com.util.TestCron? — Stanislav

In your invocation I see -cp . $CLASSPATH. File separator used in classpath is : on linux environment, therefore only current directory is included in the classpath.

I think you need to change it to -cp .:$CLASSPATH

You can't use * in classpath. I suggest you find an introductory text on setting up classpath and make sure you understand it.
