Re: Help with Byte Array to PDF
Hi, You need to not use the embedded tomcat server and point the hosted mode to your real server (e.g. localhost:8080). You do this using the -noserver option passed to the GWTShell.

Using Ian's technique you can write a simple servlet like he said, generate thePDFusing the stored data, and set the content type to application/pdfbefore writing the bytestream to the servlet's output stream (you can find this inside the HttpResponse object). This will tell the browser that aPDFis coming it's way and it will automatically handle it appropriately.

Help with Byte Array to PDF
