a problem about jboss

shihuaguo Nov 13, 2006 10:52 AM

a example to demonstrate this problem:
two jsp pages:
hello.jsp:

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<HTML>
 <HEAD> <title>Input Name Page</title> </HEAD>
 <body bgcolor="white">
 <f:view>
 <h:form id="helloForm">
 <h:commandLink value="Say hello" action="sayhello"></h:commandLink>
 <h:commandLink value="Say hello2" action="sayhello"></h:commandLink>
 </h:form>
 </f:view>
 </body>
</HTML>

sayhello.jsp

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>

<f:view>
 <h3>
 <t:outputText value="hello"/>
 </h3>
</f:view>

faces-config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config
PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN"
 "http://java.sun.com/dtd/web-facesconfig_1_0.dtd">
<faces-config>

 <navigation-rule>
 <from-view-id>/test/hello.jsp</from-view-id>
 <navigation-case>
 <from-outcome>sayhello</from-outcome>
 <to-view-id>/test/sayhello.jsp</to-view-id>
 <redirect />
 </navigation-case>
 </navigation-rule>

</faces-config>

web.xml:

 <listener>
 <listener-class>
 org.apache.myfaces.webapp.StartupServletContextListener
 </listener-class>
 </listener>
 <servlet>
 <servlet-name>FacesServlet</servlet-name>
 <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
 <load-on-startup>1</load-on-startup>
 </servlet>
 <servlet-mapping>
 <servlet-name>FacesServlet</servlet-name>
 <url-pattern>/faces/*</url-pattern>
 </servlet-mapping>


 <filter>
 <filter-name>LogFilter</filter-name>
 <filter-class>com.recency.XY0631.filter.LogFilter</filter-class>
 </filter>
 <filter-mapping>
 <filter-name>LogFilter</filter-name>
 <url-pattern>*.jsp</url-pattern>
 </filter-mapping>

then i did the following steps:
1, i visit hello.jsp in my internet explorer, the logger print "request url=.../hello.jsp" in console.
2,i click "Say hello" link , the page direct to sayhello.jsp , the logger print "request url=.../sayhello.jsp" in console.
3,i push "back" button on internet explorer, the page return to .../hello.jsp,the logger didn't print anything.
4,i click "Say hello" link , page didn't direct to sayhello.jsp ,the logger printed "request url=.../hello.jsp", (they acted as what they did in step 1)
5,i clicked "Say hello" link again, the page direct to sayhello.jsp ,the logger printed "request url=.../sayhello.jsp".
why i hava to click "Say hello" link twice?(i have used tomcat instead, it don't hava this problem)
is this a jboss's bug ?(i found the jbpm-starters-kit-3.1.2's default jboss server also have this problem)
thanks for any help.
