Streaming PDF file with the bean:write tag -- please help

[le...@bankone.com]

I would like to be able to display/stream the PDF file in the browser and
use the <bean:write> tag in the JSP to acomplish that.
Say I have a form bean that has a byte array field, and I want the jsp to
specify the contentType as "application/pdf" and just have the bean:write
tag, such as:

<bean:write name="mybean" property="pdfcontent"/>

Is this possible to achieve? Are there any hacks/tricks to make it work in
a JSP when the form bean has the binary content field?

When I do it with with the byte array attribute, it just displays the
address of the array in memory (possibly calls toString()). If I make the
field of type String and convert the byte array to String in the
controller as follows: str = new String(byteArray),  it does not get
converted correctly and the browser hangs.

I know the best way to do it is to have a servlet. But I need to do it in
a JSP because of certain limitations of my application. Please help.

Thanks.

This is a Struts User question, so please post it in the Users List.

I just wonder why you want to use a jsp for this. Normally I would use a servlet for binary content.
