Intro

I am rendering a chart to the output stream. Instead of streaming it directly to the response.out, I create a ChartResult, and let webwork do the chaining for me.

I generate the chart in one class, and I render it out in another class, effectively decoupling the view from the actionsActions. You can easily render it out to a file or some view other than a web response.out if you wish.

Configuration

xwork.xml - result-types definitions

code

Code Block
xml xml title action.xml
<result-types> <result-type name="chart" class="myapp.webwork.extensions.ChartResult"/> </result-types>

xwork.xml - action definitions

code

Code Block
xml xml title action.xml
<action name="viewModerationChart" class="myapp.webwork.actions.ViewModerationChartAction"> <result name="success" type="chart"> <param name="width">400</param> <param name="height">300</param> </result> </action>

...

Code Block
<param name="width">400</param> <param name="height">300</param>
