Hi heikki!
I needed the same so I did following:
extending AbstractResource
implemented the needed:
protected ResourceResponse newResourceResponse(Attributes attributes) {
ResourceResponse resourceResponse = new ResourceResponse();
final StringBuilder sb = new StringBuilder();
//do sb.append() here your json etc.
resourceResponse.setWriteCallback(new WriteCallback() {
@Override
public void writeData(Attributes attributes) throws
IOException {
Response response = attributes.getResponse();
response.write(sb.toString());
}
});
resourceResponse.setContentType("application/json");
return resourceResponse;
}
written a subclass of ResourceReference which takes a Class as
constructor parameter.
@Martin: why doesn't wicket hasn't something generic?
public class GenericResourceReference extends ResourceReference {
private Class<? extends IResource> iResourceClass;
public GenericResourceReference(Class<? extends IResource>
iResourceClass) {
super(iResourceClass.getName());
this.iResourceClass = iResourceClass;
}
@Override
public IResource getResource() {
try {
return iResourceClass.newInstance();
} catch (InstantiationException e) {
throw new RuntimeException(e);
} catch (IllegalAccessException e) {
throw new RuntimeException(e);
}
}
and mounted it in the WebApplication init() method like this:
mountResource("/my.json", new GenericResourceReference(MyResource.class));

thanks,
that example does indeed work fine, but I'd rather have *no* markup file,
just generate the XML or JSON myself and send that back in the response.
So I need a mounted IResource to do that ? Any tip how to go about it for
this use case, e.g. use a ByteArrayResource ?
