problem with creating MediaOutput in javabean

[orkun]

hello

I tried to create MediaOutput component in javabean, bu nothing was seen

here is the code;


MediaOutput myMedia = new MediaOutput ();

String style = "width:600px ; height:450px ; border=1px";
myMedia.setStyle(style);
myMedia.setCacheable(false);
myMedia.setId("foto2");

ExpressionFactory expressionFactory = FacesContext.getCurrentInstance().getApplication().getExpressionFactory();

ELContext elContext = FacesContext.getCurrentInstance().getELContext();

MethodExpression mediaMethodExpression = expressionFactory.createMethodExpression(elContext,
"#{haritaBean1.drawFoto}",
null,
new Class[] {OutputStream.class,Object.class} );

myMedia.setCreateContentExpression(mediaMethodExpression);
myMedia.setCacheable(false);

children.add(myMedia); // a PanelGrid component.

how can I solve this problem ?

regards

Hi,

First check what's rendered on the page (is there IMG tag, does it have "uri" attribute, etc.). If it's ok, then this method should render resource contents: org.ajax4jsf.resource.UserResource.send(ResourceContext) - you can set breakpoint there and check what's wrong.

thank you

So, there is no problem java code above ?

Yes, code looks ok by quick inspection, but I haven't tried to run it.

hello

I am sorry to extend the question.

Nothing is displayed. But I get null exception as:

javax.servlet.ServletException: Required attribute element for component harita:fotoBean is null.

Isn't my java code to view the image

MethodExpression mediaMethodExpression = expressionFactory.createMethodExpression(elContext,
"#{haritaBean1.drawFoto}",
null,
new Class[] {OutputStream.class,Object.class} );

---------------

drawFoto works statically.

public void drawFoto(OutputStream output, Object object) {

System.out.println(" I am in drawFoto---------------");

try {
if (getFoto_byte().length > 0) {
System.out.println("draw foto ");
System.out.println("------------------------");

output.write(getFoto_byte());
output.flush();

} else {
System.out.println("getFoto_byte().length : "
+ getFoto_byte().length);
}

output.close();

} catch (IOException e) {
// TODO Auto-generated catch block
System.out.println("**ORKUN ***" + "fotoda da sıkıntı var");
e.printStackTrace();
}


}

Ok, looks like you have to add setElement() call.
