[jira] Commented: (OPENJPA-878) Support default query hint for query timeout

["Donald Woods (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENJPA-878?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12671906#action_12671906 ] 

Donald Woods commented on OPENJPA-878:
--------------------------------------

A new hint can be supplied -
    javax.persistence.query.timeout     // time in seconds
Can be used in the following:
    Methods - Query.setHint()
    Annotations - NamedQuery, NativeNamedQuery
    Properties - Persistence.createEntityManagerFactory, persistence.xml
The following methods can return a javax.persistence.QueryTimeoutException:  getResultList(), getSingleResult(), executeUpdate().
If a QTE is thrown, the current transaction (if active) should not be marked for rollback.
