Configuring the response content type in Struts2

Question

So, I use freemarker templates with Struts2 to formulate my answers. However, since I am also trying to use taconite, I need an answer that will be sent with the content type "text / xml". I cannot find a way to use freemarker directives to set the content type, and I am not good at struts to find out if there is a way to do this through.

So how do I do this?

Answer 1

Or you can set it in struts.xml

<action name="..." class="...">
  <result name="SUCCESS">
    <param name="contentType">text/html</param>

Answer 2

Action ServletResponseAware :

package your.package;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.opensymphony.xwork2.ActionSupport;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;

public class YourAction extends ActionSupport implements 
                 ServletResponseAware {

  private HttpServletResponse response;

  public String execute() throws Exception{
    response.setContentType("image/png");
    return SUCCESS;
  }

  public void setServletResponse(HttpServletResponse response){
    this.response = response;
  }

  public HttpServletResponse getServletResponse(){
    return response;
  }
}
