Hi,

Is it possible for a named sql query return Integer object?
Code:
   <sql-query name="findLogicalSequence">
      <return class="java.lang.Integer">
       </return>   
      select max(metaobjectno) + 1 as metaobjectno from metaobject where structureno = :structureno
   </sql-query>


I tried with above definition and as expected, it threw an exception as

Code:
Caused by: org.hibernate.MappingException: Unknown entity: java.lang.Integer
   at org.hibernate.impl.SessionFactoryImpl.getEntityPersister(SessionFactoryImpl.java:569)
   at org.hibernate.loader.custom.SQLQueryReturnProcessor.getSQLLoadable(SQLQueryReturnProcessor.java:53)
   at org.hibernate.loader.custom.SQLQueryReturnProcessor.processRootReturn(SQLQueryReturnProcessor.java:119)
   at org.hibernate.loader.custom.SQLQueryReturnProcessor.processReturn(SQLQueryReturnProcessor.java:98)
   at org.hibernate.loader.custom.SQLQueryReturnProcessor.process(SQLQueryReturnProcessor.java:87)
   at org.hibernate.loader.custom.SQLCustomQuery.<init>(SQLCustomQuery.java:105)
