Thank you for your help. I corrected those two oversights, and got the class working successfully by changing the onActivate() parameter from byte[] to 'User' (code below). The image now displays, but I wonder if when passing a 'User' object Tapestry passes just the id as reference (using Tapestry-Hibernate ValueEncoder), or whether I ought to explicitly pass the id like so: user.getId().
Also, Welcome.tml will untimately display several images from the database, of different entity types and multiple instances. I'm wondering how BlobImage.class might be called numerous times from the same template. Finally, I tried your shorter alternative: "return "data:image/png;base64," + Base64.getUrlEncoder().encodeToString(user.getImage());". It didn't work; the compiler seemed to point to the Java version (I use 1.8). Thanks, Chris.
