This doesn't work, since the value of the src attribute should be a URL that
points to image data, not the data itself. Fortunately, there's an easy way to
create this mapping. In your action bean, you need an event handler that
streams the image data:
@HandlesEvent("image")
public Resolution provideImageData() {
return new StreamingResolution("image/png") {
public void forgotHowThisMethodIsCalled(HttpServletRequest request,
HttpServletResponse response) throws IoException {
response.getWriter().write(imageData, 0, imageData.length);
}
}
}
(There are probably all kinds of things wrong with this snippet, but I hope
that it gives an idea.)
With this method in place, it's a matter of putting a stripes:url in your JSP
that points to the new event handler. You might want to add a dummy parameter
(&name=image.png) to convince older browsers that the resource really is an
image.
