Results

Webwork provides several implementations of the com.opensymphony.xwork.Result interface to make web-based interactions with your actions simple. These results include:

Result Type	name	class
#Dispatcher	dispatcher	com.opensymphony.webwork.dispatcher.ServletDispatcherResult
#Redirect	redirect	com.opensymphony.webwork.dispatcher.ServletRedirectResult
#Action Chaining	chain	com.opensymphony.xwork.ActionChainResult
#Velocity	velocity	com.opensymphony.webwork.dispatcher.VelocityResult
#FreeMarker	freemarker	com.opensymphony.webwork.views.freemarker.FreemarkerResult
#JasperReports	jasper	com.opensymphony.webwork.views.jasperreports.JasperReportsResult
#XML/XSL	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:

<action name="bar" class="myPackage.barAction">
  <result name="success" type="dispatcher">
    <param name="location">foo.jsp</param>
  </result>
</action>

or

<action name="bar" class="myPackage.barAction">
  <result name="success" type="dispatcher">foo.jsp</result>
</action>

Dispatcher

Includes or forwards a view (usually a jsp)

Parameters	Description
location	the location to go to after execution (ex. jsp)
parse	true by default. If set to false, the location param will not be parsed for expressions

<result name="success" type="dispatcher">
    <param name="location">foo.jsp</param>
</result>

Redirect

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 expressions.

Parameters	Description
location	the location to go to after execution
parse	true by default. If set to false, the location param will not be parsed for expressions

<result name="success" type="redirect">
    <param name="location">foo.jsp</param>
    <param name="parse">false</param>
</result>

Action Chaining

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	Description
actionName	the name of the action that will be chained to

<result name="success" type="chain">
    <param name="actionName">bar</param>
</result>

invokes this

<action name="bar" class="myPackage.barAction">
    ...
</action>

Velocity

This result mocks a JSP execution environment and then displays a Velocity template that will be streamed directly to the servlet output.

Parameters	Description
location	the location to go to after execution
parse	true by default. If set to false, the location param will not be parsed for expressions

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

FreeMarker

Parameters	Description
location	the location to go to after execution
parse	true by default. If set to false, the location param will not be parsed for expressions
contentType	defaults to "text/html" unless specified

<result name="success" type="freemarker">foo.ftl</result>

JasperReports

Generates a JasperReports report using the specified format or PDF if no format is specified.

Parameters	Description
location	the location to go to after execution
parse	true by default. If set to false, the location param will not be parsed for expressions
dataSource	the Ognl expression used to retrieve the datasource from the value stack (usually a List)
format	the format in which the report should be generated, defaults to pdf

<result name="success" type="jasper">
    <param name="location">foo.jasper</param>
    <param name="dataSource">mySource</param>
     <param name="format">CSV</param>
</result>

or for pdf

<result name="success" type="jasper">
    <param name="location">foo.jasper</param>
    <param name="dataSource">mySource</param>
</result>

XML/XSL

Interfaces with xml transformations.

Parameters	Description
location	the location to go to after execution
parse	?? looks to be false unless specified

<result name="success" type="xslt">foo.xslt</result>
