THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Webwork provides several implementations of the com.opensymphony.xwork.Result interface to make web-based interactions with your actions simple. These results result types include:
Result Type | name | class |
|---|---|---|
dispatcher | com.opensymphony.webwork.dispatcher.ServletDispatcherResult | |
redirect | com.opensymphony.webwork.dispatcher.ServletRedirectResult | |
chain | com.opensymphony.xwork.ActionChainResult | |
velocity | com.opensymphony.webwork.dispatcher.VelocityResult | |
freemarker | com.opensymphony.webwork.views.freemarker.FreemarkerResult | |
jasper | com.opensymphony.webwork.views.jasperreports.JasperReportsResult | |
xslt | com.opensymphony.webwork.views.xslt.XSLTResult |
Results are specified in xwork.xml nested inside actions. The "location" param is the default parameter, meaning you can specify the location two ways:
...
Includes or forwards a view (usually a jsp)
Parameters | Required | Description |
|---|---|---|
location | yes | the location to go to after execution (ex. jsp) |
parse | no | true by default. If set to false, the location param will not be parsed for Ognl expressions |
| Code Block |
|---|
<result name="success" type="dispatcher">
<param name="location">foo.jsp</param>
</result>
|
...
The response is told to redirect the browser to the specified location. The consequence of doing this means that the action that was just executed is lost or no longer available. This is because actions are built on a single-thread model.
NOTE: You may want to set the parse attribute to false so the location is not parsed for Ognl expressions.
Parameters | Required | Description |
|---|---|---|
location | yes | the location to go to after execution |
parse | no | true by default. If set to false, the location param will not be parsed for Ognl expressions |
| Code Block |
|---|
<result name="success" type="redirect">
<param name="location">foo.jsp</param>
<param name="parse">false</param>
</result>
|
...
A special kind of view that invokes GenericDispatch (using the previously existing ActionContext) and executes another action. This is useful if you need to execute one action immediately after another.
Parameters | Required | Description |
|---|---|---|
actionName | yes | the name of the action that will be chained to |
...
This result mocks a JSP execution environment and then displays a Velocity template that will be streamed directly to the servlet output.
Parameters | Required | Description |

| Code Block |

<result name="success" type="velocity">
<param name="location">foo.vm</param>
</result>
