class not found exception

i'm trying to run a web application in eclipse using springs and hibernate.

the dispatcher-servlet.xml is,

<?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.xsd">

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" />

    <bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>

        <property name="username" value="root"/>
        <property name="password" value="mysql"/>
    </bean>

    <bean id="mySessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="myDataSource" />
        <property name="annotatedClasses">
            <list>
                <value>com.vaannila.domain.User</value>
            </list>
        </property>


        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">create</prop>
            </props>
        </property>
    </bean>

    <bean id="myUserDAO" class="com.vaannila.dao.UserDAOImpl">
        <property name="sessionFactory" ref="mySessionFactory"/>
    </bean>

    <bean name="/user/*.htm" class="com.vaannila.web.UserController" >
        <property name="userDAO" ref="myUserDAO" />
    </bean>

</beans>

the error i get is,

The class com.vaannila.domain.User is in the Java Resources:src folder of the project in eclipse.

Always check the 'Problems" tab/view in eclipse. i was getting the same issue and reason was simple that i included "org.springframework.spring-library-3.1.0.RELEASE.libd" file as library when i was configuring the build path and this was in the same "dist" folder. so i just removed that and everything works fine.

It is easy, it is the collision happened in the library you include .please check the lib you included, in the path :

   tomcat6/webapps/<you project name>/WEB-INF/lib/

you possible find two file named like : asm.jar and asm-2.x.x.jar the two jar file come from different source, one from the spring the other from hibernate,so there is some collision happened here, tomcat cannot decide which jar to added.so it report the exception.

i try the code, and everything is working fine.

at first i suspect <list> will give the instance of List not array, but when i try it, it doing fine.

spring will throw error like you write above if they cannot find the class that you suppose to include in this case com.vaannila.domain.User

check your output folder for compiled class. is there User.class exist and successfully compiled?

  1. Check that class should be there in src/com/vannila/domain/User.java

  2. check that class is annotated as shown here.and compare where you missed the thing

Please create package in eclipse and add User.java to the package.
