java - Setting the content-type of a response in Struts2

Question

So, I'm using freemarker templates with Struts2 to formulate my responses. However, since I'm trying to use taconite as well, I need the response to be sent with the content type of "text/xml". I can't seem to find a way to use freemarker directives to set the content type, and I am not well versed enough in struts to know if there is a way to do it through that.

So, how should I go about this?

Answer 1

In your Action class, implements the ServletResponseAware interface, and use a simple:

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;
  }
}
