I have 2 questions... 1.  I'm using Eclipse Helios SR2.  I'm not able to get the proper pluging to have JBOSS AS as my server in eclipse.      I got several sites in net for the plugin, but when i tried to install it says conflicting, and it closes.      Can i add Jboss 7 AS to my eclipse ? 2.  I'm using spring 2.5, JSF and hibernate application.       The problem is i have used annotation for component and repository  but it is not getting initialized.   Basically  spring component scanner is not working.      Please find the code snippets:      Web.xml:     <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns="http://java.sun.com/xml/ns/javaee"     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee       http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"     version="2.5">     <listener>         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>     </listener>     <listener>       <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>     </listener>         <context-param>         <param-name>contextConfigLocation</param-name>         <param-value>/WEB-INF/applicationContext.xml</param-value>     </context-param> 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"        xmlns:context="http://www.springframework.org/schema/context"        xsi:schemaLocation="http://www.springframework.org/schema/beans            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd            http://www.springframework.org/schema/context            http://www.springframework.org/schema/context/spring-context-3.0.xsd"...                    <context:component-scan base-package="main.controllerbeans" />     <context:annotation-config />         <bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">         <property name="locations">             <list><value>/WEB-INF/configuration.properties</value></list>         </property>     </bean>         <!-- IMPORTING HIBERNATE SETTINGS -->     <import resource="/db-config.xml"/> Component scan is not working... it seems db-config.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" xmlns:p="http://www.springframework.org/schema/p"     xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"...     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">         <property name="driverClass">             <value>${jdbc.driver.className}</value>         </property>         <property name="jdbcUrl">             <value>${jdbc.url}</value>         </property>         <property name="user">             <value>${jdbc.username}</value>         </property>         <property name="password">             <value>${jdbc.password}</value>         </property>     </bean>     <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">         <property name="dataSource">             <ref bean="dataSource" />         </property>         <!-- <property name="packagesToScan" value="main.dbentities" /> -->                 <property name="hibernateProperties">             <props>                 <prop key="hibernate.dialect">${jdbc.hibernate.dialect}</prop>                 <prop key="hibernate.show_sql">false</prop>             </props>         </property>                 <property name="packagesToScan" value="org.adit.spring.hibernate.entity" />                  </bean>     <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">         <property name="sessionFactory">             <ref bean="sessionFactory" />         </property>     </bean>     <context:annotation-config />     <tx:annotation-driven />             </beans> faces-config.xml <?xml version="1.0"?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee       http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"    version="2.0">     <application>          <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>     </application> NotificationBean.java import java.io.Serializable;
