Hi,

I want to print my file directly from webpage. For that I am using following reference and trying to implement same with ZUL and Composer.

tonny-bruckers.blogspot.in - 2012/11/printing-files-directly-from-web-page.html

ZUL File :-

<zk>
<applet code = "PrintApplet.class" codebase = "applet/" id="printApplet" width="400px" style="border: 1px" />
<button id="btnClickMe" label="Click Me" sclass="light-btn"/>
</zk>

PrintApplet.class is present inside "WebContent/applet".

public class AppletComposer extends GenericForwardComposer<Window> {
    private Applet printApplet;
    public void doOverrideAfterComposer(Window comp) throws Exception {

    }
    public void onClick$btnClickMe(Event event) throws Exception {
        String Originalstr = "ByteArrayInputStream Example!";
        byte[] Originalbytes = Originalstr.getBytes();
            ByteArrayInputStream bis=new ByteArrayInputStream(Originalbytes);
        printApplet.invoke("print", bis);
    }
}

PrintApplet Class :-

public class PrintApplet extends Applet {
    public void init() 
    {

    }
    public void print(ByteArrayInputStream bis) throws PrintException 
    {
        PrintService service = PrintServiceLookup.lookupDefaultPrintService();
        if (service != null) {
            DocFlavor psFormat = DocFlavor.INPUT_STREAM.PDF;
            PrintRequestAttributeSet attributes = new HashPrintRequestAttributeSet();    
            DocPrintJob job = service.createPrintJob();
            Doc pdfDoc = new SimpleDoc(bis,psFormat, null);
            job.print(pdfDoc, attributes);         
        }
    }
}

I am able to invoke PrintApplet with this approach but getting Null as service. PrintApplet is working fine with AppletViewer and with normal Java Application but unable to get default printer service while using the above approach.
