Hi yo'all,
I did quite a lot Googling and searched this forum, but still did not find
what I was looking for.
Basically I need to create pages that respond with xml content with
"text/xml" content-type.
In some posts, Igor suggested to overwrite "configureResponse" method. So I
tried the following
@Override
protected void configureResponse(WebResponse response) {
response.setContentType("text/xml");
super.configureResponse(response);
}
which does not work. The page response's content-type is still "text/html".
I also tried to overwrite "getMarkupType" method, as shown here
@Override
public MarkupType getMarkupType() {
return new MarkupType("xml", MarkupType.XML_MIME);
}
which also does not work and throws
"org.apache.wicket.markup.MarkupNotFoundException: Can not determine Markup.
Component is not yet connected to a parent. [Page class = SomePage, id = 3,
render count = 1]".
One user who was asking questions on this forum created the following
article, which could serve my purpose.
http://blog.brunoborges.com.br/2008/11/restful-web-services-with-wicket.html
So I migrated his code to Wicket 1.5, as shown below.
import org.apache.wicket.Component;
import org.apache.wicket.behavior.Behavior;
import org.apache.wicket.markup.MarkupType;
import org.apache.wicket.markup.html.WebPage;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
/**

public class RestXmlPage extends WebPage {
public RestXmlPage() {
setStatelessHint(true);
}
private CharSequence getXML() {
return "<top><id><12></id><name>round n round</name></top>";
}
@Override
protected void onRender() {
try {
PrintWriter pw = new PrintWriter(((HttpServletResponse)
getResponse().getContainerResponse()).getOutputStream());
pw.write(getXML().toString());
pw.close();
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public MarkupType getMarkupType() {
return new MarkupType("xml", MarkupType.XML_MIME);
}
@Override
public final boolean hasAssociatedMarkup() {
return false;
}
@Override
public final Component add(Behavior... behaviors) {
throw new UnsupportedOperationException(
"WebServicePage does not support IBehaviours");
}
}
But this page also throws "org.apache.wicket.markup.MarkupNotFoundException:
Can not determine Markup. Component is not yet connected to a parent."
exception.
Could anyone spare some time and help me with this?
Thanks a lot!
