Home > FAQs > How do we access static parameters from an Action

Static (or pre-defined) parameters can be set to a Map property or to individual JavaBean properties.

  • Define the parameters to be set by adding the name(s) and value(s) to the action mapping element (in the application's struts.xml.
<action name="myAction" class=" MyAction">
     <param name="myStaticParam1">myStaticValue1</param>
     <param name="myStaticParam2">myStaticValue2</param>
     <param name="myStaticParam3">myStaticValue3</param>
  • Ensure that staticParams Interceptor is included in the Action's stack.
    • (info) The default stack already includes staticParams.
  • Edit the Action so that it implements the Parameterizable interface.

Map property

  • Ensure the Action defines a setParams(Map) method.
  • The staticParams Interceptor will set the defined values to the Map, using the name as the entry key.









JavaBean properties

  • Ensure that the Action defines JavaBean properties corresponding to the param elements in the action mapping.
  • The staticParams Interceptor will set the defined values to each JavaBean property that corresponds to a param element.
public String getMyStaticParam1()
public void setMyStaticParam1(String myStaticParam1)

public String getMyStaticParam2()
public void setMyStaticParam2(String myStaticParam2)

public String getMyStaticParam3()
public void setMyStaticParam3(String myStaticParam3)
