Data service connection: BlazeDS root and/or RDS server

Hello all,

I already went through the very well written and clear tutorials of Flex and Flash builder. Now I am trying to develop alone my first felx-spring application.

here is my web.xml:

<?xml version="1.0" encoding="UTF-8"?><web-app xmlns="http://java.sun.com/xml/ns/j2ee"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee   http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">   <servlet>      <servlet-name>spring</servlet-name>         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>         <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/services-config.xml</param-value>         </init-param>         <load-on-startup>1</load-on-startup>   </servlet>   <servlet-mapping>       <servlet-name>spring</servlet-name>       <url-pattern>/messagebroker/*</url-pattern>   </servlet-mapping>     </web-app>

and my services-config.xml:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:flex="http://www.springframework.org/schema/flex"       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          http://www.springframework.org/schema/flex          http://www.springframework.org/schema/flex/spring-flex-1.0.xsd">   <flex:message-broker/>   <bean id="employeeService" class="services.EmployeeServiceImpl" >      <flex:remoting-destination />      <!--constructor-arg ref="dataSource" /-->   </bean>    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">      <property name="driverClassName" value="org.h2.Driver" />      <property name="url" value="jdbc:h2:~/sprinflexdemodb/sprinflexdemodb" />   </bean>        </beans>

First: when I configured the BlazeDS and validated the configuration, I had the warning:

Server root is not pointing to a BlazeDS server root folder

Googling this message gives only two results, that roughly say: it's not really a problem.

But after, when trying to connect to the data service in the Data/Services view in Flash builder, I am asked for a password, I put nothing, then I have this error alert:

RDF server message:

Error executing RDS command. Status code : 404 , Reason: Introuvable (in french, means "not found")

 

Suggestion:

...

 

The suggestions are to make sure that there is an RDS servlet in my web.xml. Well, before this alert I haven't heared about RDS servlets in the tutorials I made. But, as suggested in someplaces on the web, I added the following in my web.xml:

<servlet>        <servlet-name>RDSDispatchServlet</servlet-name>        <servlet-class>flex.rds.server.servlet.FrontEndServlet</servlet-class>        <init-param>            <param-name>useAppserverSecurity</param-name>            <param-value>false</param-value>        </init-param>        <load-on-startup>10</load-on-startup>    </servlet>

and now I am still having the same error.

Please, any suggestions?

thanks in advance.
