Not sure if this will help, but here goes. I have Form based JSPs that can
be used across multiple actions. Therefore these JSPs have dynamic form
action attributes. I didn't want to set the form action in the Action
class. Instead I define it in struts-config.xml on a per action mapping
basis.
To accomplish this I could've used the parameter attribute of the action
mapping and then in my JSP do something like this:
<bean:define id="mapping" name="<%= org.apache.struts.Globals.MAPPING_KEY
%>"/>
<html:form action="<%= mapping.getParameter() %>" ...>
And in struts-config.xml have something like this:
<action path="/actionA" type="com.blah.FirstAction" name="myForm"
parameter="/actionX">
<forward name="success" path="/myReusableFormPage.jsp"/>
</action>
<action path="/actionB" type="com.blah.SecondAction" name="myForm"
parameter="/actionY">
<forward name="success" path="/myReusableFormPage.jsp"/>
</action>
However I also wanted the ability to apply other properties to action
mappings so the JSP could be generic. Therefore instead of using the
parameter attribute I defined my own ActionMapping subclass and make use of
the set-property element of the action mapping. My subclass has a single
Map property called "property".
public class PropertiesActionMapping extends ActionMapping {
private Map property = new Hashtable();
public PropertiesActionMapping() {
}
public Map getProperty() {
return property;
}
public void setProperty(Map value) {
property = value;
}
}
Now in struts-config.xml I can do this:
<action path="/actionA" type="com.blah.FirstAction" name="myForm"
className="com.blah.PropertiesActionMapping">
<set-property property="property(titleKey)" value="actionX.title"/>
<set-property property="property(formAction)" value="/actionX"/>
<forward name="success" path="/myReusableFormPage.jsp"/>
</action>
<action path="/actionB" type="com.blah.SecondAction" name="myForm"
className="com.blah.PropertiesActionMapping">
<set-property property="property(titleKey)" value="actionY.title"/>
<set-property property="property(formAction)" value="/actionY"/>
<forward name="success" path="/myReusableFormPage.jsp"/>
</action>
And now the JSP looks like this:
<bean:define id="mapping" name="<%= org.apache.struts.Globals.MAPPING_KEY
%>"/>
<title><bean:message name="mapping" property="property(titleKey)"/></title>
...
<html:form action='<%= mapping.getProperty("formAction") %>' ...>
The code I've shown above isn't actually how I do it since I'm using the
JSTL-EL.
