Generating Dynamic MediaOutput using Java gives an error

[kapil29]

Hello

I am trying to generate the Media Ouput componets to display the uploaded Image into the panel dynamically using JAVA code, but when I am trying to upload the image and reRender the thumbnail panel it gives me error "paint()" not found i.e. "javax.el.MethodNotFoundException: Method not found: [e-mail]()". But the same is declared in my action controller class i.e "ProjectController.java" Class

Here are my code

                    HtmlPanel thumbnailPanel = new HtmlPanel();
                    thumbnailPanel.setId("thumbnail_panel");

                    MediaOutput mediaOutput = new MediaOutput();
                    mediaOutput.setElement("img");
                    mediaOutput.setCacheable(false);
                    mediaOutput.setSession(true);
                    mediaOutput.setRendered(true);
                    mediaOutput.setValueExpression("mimeType", application.getExpressionFactory().createValueExpression(context.getELContext(),                     "#{projectBean.creativeWraper["+ i +"].mimeType}" , String.class));
                   

                    mediaOutput.setValueExpression("value", application.getExpressionFactory().createValueExpression(context.getELContext(),                     "#{projectBean.creativeWraper["+ i +"].fileName}" , String.class));

                    MethodExpression createContentExpressionObj = FacesContext.getCurrentInstance().getApplication().getExpressionFactory().

                            createMethodExpression(context.getELContext(), "#{projectController.paint}", null, new Class<?>[0]);
                    mediaOutput.setCreateContentExpression(createContentExpressionObj);

                    thumbnailPanel.getChildren().add(mediaOutput);

ProjectController.java

public void paint(OutputStream stream, Object object) throws IOException {

// code for painting the image

}

Is there anything missed to add in my code?

Kinldy help.....

Hi Kapil,

You are passing incorrect signature classes when you create MethodExptression:

createMethodExpression(context.getELContext(), "#{projectController.paint}", null, new Class<?>[0]);

There array of OutputStream.class & Object.class should be passed.
