How to prevent for update usage in one ejbSelect method in r
I've created an ejbSelect statement that uses the following ejbQL:
<query-method>
<method-name>ejbSelectMaxDBID</method-name>
<method-params/>
</query-method>
<result-type-mapping>Local</result-type-mapping>
<ejb-ql>select max( o.orderdbid ) from OrderTable o</ejb-ql>
I've set this bean with <row-locking> true because I would like the bean to lock the rows whenever its loaded. However I get the error below.... How do I turn off Row locking for this ejb-select method only? Is this possible with declared-sql or jboss-ql?
Isnt this a jboss bug? I dont think for update should be used in methods where any function is present...
18:11:59,131 DEBUG [OrderTable#ejbSelectMaxOrderId] Find failed
