Why the multiple sql select for findByPrimaryKey JBoss 4.01

[askesis]

Why does JBoss generate multiple select statements (see log below) for a single findByPrimaryKey finder?

As I suspected that it is had something to do with the read-ahead-strategy I have tried to use the XDoclet tag @jboss.read-ahead strategy = "none" but that did not change anything

TIA

By setting read-ahead strategy to none you default it to the lazy-loading and it will do the multiple select statements.
Try checking Chapter 11 "Optimized Loading" of the Administration document. This chapter explains the loading optimization.
