Hi folks, I've been tracking down and fixing ISIS-714 [1], which is that Blobs and Clobs are currently persisted as serialized Java objects, rather than (as intended) as multiple columns in the database (for name, mime type and varbinary, say). This will be fixed in 1.5.0, which I hope to release in a week or two.
In doing so I've realized that some additional annotations are required in the domain; this is now written up on our website [2]. ~~~ And, while you're on the website, do notice our spiffy "fork me on github" banner. (I'm presuming its ok to do this; one or two of the other apache projects have a similar banner). Cheers Dan [1] https://issues.apache.org/jira/browse/ISIS-714 [2] http://isis.apache.org/components/objectstores/jdo/mapping-blobs.html
