How to get HttpSession using HttpInvokerServiceExporter?

[Mikhail.spb]

Good day.

I am new to Spring and I don't know if its possible to get HttpSession from "plainService" object using HttpInvokerServiceExporter?

Firstly I create plainService bean - class which implements interface with rpc methods.
Secondly create invoker bean using plainService bean and interface with rpc methods
And finally create urlMapping bean using invoker

It works correctly but I don't know how to get HttpSession object in PlainServiceImpl class.
Have any idea?

There are my classes:
=========================
common.PlainService interface
=========================

public interface PlainService { 
	
    String getDummyText();
}

=========================
common.PlainService interface implementation
=========================

public class PlainServiceImpl implements PlainService {
    public String getDummyText() {
	return "DummyText";
    }
}

config files:
=========================
springContext.xml
=========================

<bean id="plainService" class="service.impl.PlainServiceImpl"></bean>

<bean id="invoker" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
    <property name="service" ref="plainService" />
    <property name="serviceInterface" value="common.plainService"/>
</bean>

<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings"> 
	<props>
	    <prop key="/plain.service">invoker</prop>
	</props>
    </property>
</bean>

=========================
WEB-INF/web.xml
=========================

<servlet>
    <servlet-name>servlet-service</servlet-name>
		
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <init-param>
	<param-name>contextConfigLocation</param-name>
    	<param-value>classpath:springContext.xml</param-value>
    </init-param>
</servlet>

What do you want to achieve with httpSessions?

[Mikhail.spb]

I need to embed authorization mechanism in my GWT application, thats why I have to use httpSession to determine if user have rights to perform any rpc queries.

I'd suggest using Spring Security then, I guess they already have a solution for it out of the box.
