HelloWorld Spring application throws Exception in thread "main": java.lang.NoClassDefFound -

i trying develop spring "helloworld" project while runing application gives me error:

info: loading xml bean definitions class path resource [beans.xml] exception in thread "main" java.lang.noclassdeffounderror: org.springframework.expression.expressionparser

below code:

package com.tutorialspoint;  public class helloworld {     private string message;      public void getmessage() {         system.out.println("your message : "+message);     }      public void setmessage(string message) {         this.message = message;     } } 

and

package com.tutorialspoint;  import org.springframework.context.applicationcontext; import org.springframework.context.support.classpathxmlapplicationcontext;  public class mainapp {     public static void main(string[] args) {     applicationcontext context = new classpathxmlapplicationcontext("beans.xml");          helloworld obj = (helloworld) context.getbean("helloworld ");     obj.getmessage();     // todo auto-generated method stub     } } 

applicationcontext.xml:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"        xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"        xsi:schemalocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">      <bean id="helloworld" class="com.tutorialspoint/helloworld">         <property name="message" value="hello world!"/>     </bean> </beans> 

apart adding dependent jars seems class defined within bean definition invalid

com.tutorialspoint/helloworld                   ^ 

make it,

<bean id="helloworld" class="com.tutorialspoint.helloworld">       <property name="message" value="hello world!"/> </bean> 

also context.getbean("helloworld ") should changed context.getbean("helloworld")
