一个tomcat下两个项目（ZK项目）共享session

以下内容多个用户登录时，后一个用户的信息会将前一个用户的信息冲掉，因为servletContext是application级别，希望看的本篇博客的人注意，解决方案还未完全完成，过两天再贴。

最后用的是单点登录，CAS认证，网上已有的比较成熟的解决方案。

发送项目为项目C

public void onSetTextbox(){
		Textbox texb = (Textbox)this.getFellow("texb");
		SimpleSession s = (SimpleSession) Executions.getCurrent().getDesktop().getSession();
		HttpSession session = (HttpSession) s.getNativeSession();
		session.setAttribute("username", texb.getValue());
		session.setAttribute("password", "qwert");
		session.setMaxInactiveInterval(6565);
		ServletContext ContextA = session.getServletContext();
		ContextA.setAttribute("session", session);
		//测试
		HttpSession session2 =(HttpSession)ContextA.getAttribute("session");
		System.out.println("IN SessionRangleServlet name : "+session2.getAttribute("username"));
		System.out.println("IN SessionRangleServlet name : "+session2.getAttribute("password"));
	}

接受项目为D

public void onGetTextbox() throws InterruptedException{
		
	    SimpleSession s = (SimpleSession) Executions.getCurrent().getDesktop().getSession();
	    HttpSession session1 = (HttpSession) s.getNativeSession();
	    ServletContext Context = session1.getServletContext();  
	    ServletContext ContextA= Context.getContext("/C");    
	       
	    HttpSession session2 =(HttpSession)ContextA.getAttribute("session");
		 
		String message = "base传过来的user为:"+session2.getAttribute("username")+"&&&"+session2.getAttribute("password");
		System.out.println(message);
		Messagebox.show(message);
	}

tomcat配置crossContext="true"

<Context docBase="C" path="/C" reloadable="true"  crossContext="true"  source="org.eclipse.jst.jee.server:C"/>
      <Context docBase="D" path="/D" reloadable="true" crossContext="true"  source="org.eclipse.jst.jee.server:D"/>

如果是普通的java项目session获得

HttpSession session1 =request.getSession();
