    Mini test with Spring-struts2

   Hi everyone!
   I'm a newbie. I get this issue:
   I'm starting with a simple webapp for login.
   I got a NPE while my struts action attempts run its execute method from my LoginAction extended from ActionSupport. userLogin is null and action always fail!
   

   Code:

   	public String execute() {
   		if (userLogin==null) {
   			logger.debug("No Way! userLogin is null now!");	
   		} else {
   			logger.debug("OK!!!! userLogin is initialized");
   			Utente utenteLogin = userLogin.CheckUser(this.username, this.password);
   			if (utenteLogin.validaName()) {
   				return Action.SUCCESS;	
   			} else {
   				return Action.INPUT;
   			}
   		}
   		return Action.INPUT;
   	}

   That's seems to me strange because spring works fine injecting the right bean in the same LoginAction:
   

   Code:

   	public void setUserLogin(JdbcUserDao userLogin) {
   		logger.debug("Dao setting");
   		this.userLogin = userLogin;
   		logger.debug(this.userLogin.getTesto());
   	}

   this is my simple Spring appContext:
   
   

   Code:

   	  <bean id="dbcpDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" lazy-init="true">
   	    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
   	    <property name="url" value="jdbc:mysql://localhost:3306/dbRemo" />
   	    <property name="username" value="test" />
   	    <property name="password" value="test" />
   	  </bean>
   
     	  <bean id="jdbcTemplate" class="org.remo.struts2.JdbcUserDaoImpl">
   		  <property name="dataSource" ref="dbcpDataSource"/>
   		  <property name="testo" value="OK!"/>
   	  </bean>
   
     	  <bean id="Login" class="org.remo.struts2.LoginAction">
   		  <property name="UserLogin" ref="jdbcTemplate" />
   	  </bean>

   Rememeber this is a simple testing app just to learn these frameworks.
   would you please help me.
   
   Thanx
   Remo

   Answer to myself because I found out the issues:
   
   1) I haven't added the struts2-spring-plugin-xxx.jar.
   
   2) I haven't put in struts.xml the spring objectFactory with this statement:
   

   Code:

   <constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />

   3) I haven't assigned to the action of the class attribute the same name of the bean identified in spring:
   

   Code:

   <action name="doLogin" class="loginAction">

   instead of
   

   Code:

   <action name="doLogin" class="org.xxx.yyy.loginAction">

   for the bean of spring
   

   Code:

   <bean id="loginAction" scope="prototype" class="org.remo.struts2.LoginAction">

   After that my webapp worked out fine.
   
   bye
