Problem with namespace in Struts 2

[David Wimmer]

Hello,

I tried to split my action definitions in different xml files with different namespaces.

When I am starting the project it is shown the Login site.

Now I click on submit (to force an error) the URL is this: http://localhost:8080/PeerTweetTemplate/login/Login.action

But when I am clicking then on Register the URL is this: http://localhost:8080/PeerTweetTemplate/login/RegisterPage.action and struts raises an error that the action is no mapping for the action.

My problem is, that struts 2 does not look in the default package for the action.


struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

	<constant name="struts.devMode" value="true" />
 		

	<package name="default" namespace="/" extends="struts-default">
	
	<result-types>
		<result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult"></result-type>
	</result-types>

		<action name="Login">
			<result type="tiles">/login/Login.jsp</result>
		</action>
		
		<action name="Start">
			<result>/tiles/home.jsp</result>
		</action>
		
		<action name="RegisterPage">
			<result>/register/Register.jsp</result>
		</action>
		
	</package>

	<include file="/de/peertweet/login/login.xml" />
	<include file="/de/peertweet/register/register.xml" />

</struts>

login.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	<package name="login" namespace="/login" extends="struts-default">

		<!-- Register the tiles 2 result type -->
		<result-types>
			<result-type name="tiles"
				class="org.apache.struts2.views.tiles.TilesResult"></result-type>
		</result-types>


		<action name="Name">
			<result>/login/NameCollector.jsp</result>
		</action>


		<!-- The Login action will process the login -->
		<action name="Login" class="de.peertweet.login.Login">
			<result name="input" type="tiles">loginPage</result>
			<result name="success" type="tiles">successPage</result>
			<result name="error" type="tiles">loginPage</result>
		</action>

	</package>

</struts>

register.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

	<package name="register" namespace="/register" extends="default">

		<!-- Register the tiles 2 result type -->
		<result-types>
			<result-type name="tiles"
				class="org.apache.struts2.views.tiles.TilesResult"></result-type>
		</result-types>


		


		<!-- The Login action will process the login
		<action name="Register" class="de.peertweet.register.Register">
			<result name="input" type="tiles">registerPage</result>
			<result name="success" type="tiles">successPage</result>
			<result name="error" type="tiles">registerPage</result>
		</action>
 -->
	</package>

</struts>


And one additional problem is, that each time I click on Login, struts appends an additional /login to the URL.


Hope you can help me :)

Ok
I just solved this problem for my task. I will put xmls, but more important was a location of struts.xml.
Curious, I was forced put it to sources!


struts.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//APache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<package name="default" extends="struts-default">
<action name="sayhello" class="mypackage.Hello">
<result>/response.jsp</result>
</action>
</package>
</struts>
Although Netbeans complaining on mistakes in this xml....

web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>

</filter-mapping>
<session-config>

30
</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>

my jspps:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib prefix = "s" uri="/struts-tags" %>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>Hello World!</h1>

<s:form method="post" action="sayhello">
<s:textfield name="name" label="Your name"/>
<s:submit/>
</s:form>
</body>
</html>

and second one
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%@ taglib prefix = "s" uri="/struts-tags" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1>Hello World!</h1>
I am <s:property value="message"/>
</body>
</html>

Be lucky

Also look at project's structure!

I did not want to bother a long time. So I've done all my actions in the default namespace and it works.

Nice. But I think, problem is not connected to default namespace.
I tried default namespace too, it did not work.
