No such method --> org.jboss.portal.portlet.impl.jsr168.api.

Hello,

On my xhtml page I've the following tag:

<a:mediaOutput element="img" cacheable="false" session="true" createContent="#{quoteAction.generateChart}" mimeType="image/png" />

And it seems that this entry causes the following exception as it is looking for an outputstream to write the image:

15:39:45,557 ERROR [home_prototype_portal_quote_portlet_QuoteListPortlet] The portlet threw an exception
javax.faces.FacesException: java.lang.NoSuchMethodException: org.jboss.portal.portlet.impl.jsr168.api.ResourceResponseImpl.getOutputStream()
 at org.ajax4jsf.resource.FacesResourceContext.getOutputStream(FacesResourceContext.java:124)
 at org.ajax4jsf.resource.UserResource.send(UserResource.java:108)

And obviously, the method getOutputStream does not exists as it is getPortletOutputStream. Does someone knows what I could have misconfigured.

Regards,

Try this when you generate the chart:

Object responseObject = FacesContext.getCurrentInstance().getExternalContext().getResponse();
 if (responseObject instanceof RenderResponse) {
 BufferedRenderResponseWrapper brrw = (BufferedRenderResponseWrapper)responseObject;
 RenderResponse response = brrw.getResponse();
 response.getPortletOutputStream().write(getFiles().get((Integer)object).getData());

 }else{
 //servlet response
 stream.write(getFiles().get((Integer)object).getData());
 }

The problem is that the request is not even reaching my method for generating the chart. It crashes when trying to get the outputStream (maybe a question for rich faces guys). The ajax4jsf tag need to have a method with the following parameters: genChart(OutputStream out, Object value)

So I think I've misconfigured something, because org.ajax4jsf.resource.FacesResourceContext.getOutputStream lookup the stream on ResourceResponseImpl.getOutputStream instead of ResourceResponseImpl.getPortletOutputStream.

I've done the following which solved my problem. I overwrite the class:
org.jboss.portal.portlet.impl.jsr168.api.MimeResponseImpl

and added the following:

public OutputStream getOutputStream() throws IOException {
return this.getPortletOutputStream();
}
