THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
JSP support in WebWork is very easy: by default webworkThe default configuration (struts-default.xml) configures the Dispatcher Result as the default result (see Result Types). This means any , which works well with JavaServer Pages. Any JSP 1.2+ container can work with WebWork Struts 2 JSP tags immediately.
Getting Started
Because JSP support occurs through the Dispatcher Result, which is the default result type, you don't need to specify the type attribute when configuration xworkconfiguring struts.xml:
| Code Block | ||||
|---|---|---|---|---|
| ||||
<action name="test" class="com.acme.TestAction">
<result name="success">test-success.jsp</result>
</action>
|
Then in test-success.jsp:
| Code Block | ||||
|---|---|---|---|---|
| ||||
<%@ taglib prefix="s" uri="/struts-tags" %> <html> <head> <title>Hello</title> </head> <body> Hello, <ww<s:property value="name"/> </body> </html> |
Where name is a property on your action. That's it!
Servlet / JSP Scoped Objects
The following are ways to obtain Application scope attributes, Session scope attributes, Request scope attributes, Request parameters and framework Context scope parameters:-
Application Scope Attribute
Assuming there's an attribute with name 'myApplicationAttribute' in the Application scope.
| Code Block |
|---|
<s:property value="%{#application.myApplicationAttribute}" />
|
Session Scope Attribute
Assuming there's an attribute with name 'mySessionAttribute' in the Session scope.
| Code Block |
|---|
<s:property value="%{#session.mySessionAttribute}" />
|
Request Scope Attribute
Assuming there's an attribute with name 'myRequestAttribute' in the Request scope.
| Code Block |
|---|
<s:property value="%{#request.myRequestAttribute}" />
|
Request Parameter
Assuming there's a request parameter myParameter (e.g. http://host/myApp/myAction.action?myParameter=one).
| Code Block |
|---|
<s:property value="%{#parameters.myParameter}" />
|
Context Scope Parameter
Assuming there's a parameter with the name myContextParam in our context.
| Code Block |
|---|
<s:property value="%{#myContextParam}" />
|
Tag Support
See the JSP Tags documentation for information on how to use the generic Struts Tags provided by WebWork. the framework.
Exposing the ValueStack
There are a couple of ways to obtain access to ValueStack from JSPs.
