You are way over-complicating things. If these are static resources
(your webapp/ implies that but storing the names in the db implies the
opposite), you can just refer to them by
/layout/images/product/<filename> (possibly add a context path). If
they are not static resources, e.g. users of your application upload
these images, you have to store them outside of the webapplication
context path, something like /var/<myapplication>/images/ for example.
Then you create a link to the resource and return a stream response to
a particular image with something like:
public Link getUploadedProductImage() {
return resources.createEventLink("productimage");
}
public StreamResponse onUploadedProductImage() throws
FileNotFoundException, IOException {
return new
BufferedImageStreamResponse(ImageIO.read(productImageStorage.getProductImageInputStream(productId)));
}
