generate Struts2 tag action code snippet

This tag enables developers to call actions directly from a JSP page by specifying the action name and an optional namespace. The body content of the tag is used to render the results from the Action. Any result processor defined for this action in struts.xml will be ignored, unless the executeResult parameter is specified.

Examples

public class ActionTagAction extends ActionSupport {



public String execute() throws Exception {

return "done";

}



public String doDefault() throws Exception {

ServletActionContext.getRequest().setAttribute("stringByAction", "This is a 
String put in by the action's doDefault()");

return "done";

}

}
