Displaying bytearray content in iframe

Hi , I have a requirement where I have to display a pdf in iframe or part of the webpage. Is there any way on displaying the content in bytearray in iframe .I have searched in web, but i can see options where iframe can only display contents from a file located on server. I am getting bytearray from a service. I have to use this byte array and display it in form of pdf in lower half of the webpage.I am using struts. Please advice. Thanks in advance.

JSPs should not be used for displaying binary content. Add just one enter between to JSP tags and that enter goes into the response, breaking the binary data. Servlets on the other hand can write the contents to the response output stream without a problem. You can use one as the source of the iframe.
