anonymous wrote : All jboss does if row-locking is true is just adds FOR UPDATE (or another sb-specific template) to SELECT. Everything else is db/driver's responsibility. It doesn't add FOR UPDATE to findByPrimaryKey()... even though it doesn't use DISTINCT. It looks like findByPrimaryKey() doesn't use the row locking template, which ist bad IMO.
