That makes sense, that is probably what I want, but I am still getting
the same exception.
I am calling it this way (uses SpringFramework 1.1.5 SqlMapClientDaoSupport)
public Map<Long, Integer> findCountsBySession(List<Long> sessionIds) {
return
getSqlMapClientTemplate().queryForMap("event.findCountsBySession",sessionIds,"id","count");
}
Could the List<Long> giving it problems?
