I have a String[] in a persistent entity. I've tried to add the @Lob annotation. Unfortunattly it does not works, I have the following exception:
| Caused by: java.lang.ClassCastException: [Ljava.lang.String; | at org.hibernate.type.StringClobType.nullSafeSet(StringClobType.java:56) | at org.hibernate.type.CustomType.nullSafeSet(CustomType.java:145) | at org.hibernate.persister.entity.AbstractEntityPersister.dehydrate(AbstractEntityPersister.java:1910) | at org.hibernate.persister.entity.AbstractEntityPersister.dehydrate(AbstractEntityPersister.java:1887) | at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2117) | at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:2503) | at org.hibernate.action.EntityInsertAction.execute(EntityInsertAction.java:51) | at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:248) | at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:232) | at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:139) | at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:297) | at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:27) | at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:993) | at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:340) The String[] is cast in String. Consequetly we have an exception. Moreover, array is stored in DB as CLOB (maybe a blob will be better). I used oracle10g, Embedded EJB3 RC9. Is it possible to map an String[] ? I have tried with the Basic annotation. It works only if there is few String in the array. When I try to put 200 String in the array I have the exception: Caused by: org.hibernate.exception.GenericJDBCException: Could not execute JDBC batch update | at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103) | at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:91) | at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) | at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:249) | at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:235) | at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:139) | at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:297) | at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:27) | at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:993) | at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:340) | at org.hibernate.ejb.AbstractEntityManagerImpl$1.beforeCompletion(AbstractEntityManagerImpl.java:475) | ... 20 more | Caused by: java.sql.BatchUpdateException: ORA-12899: valeur trop grande pour la colonne "ROOT"."TOTOPE"."SS" (réelle : 2134, maximum : 255) | | at oracle.jdbc.driver.DatabaseError.throwBatchUpdateException(DatabaseError.java:498) | at oracle.jdbc.driver.OraclePreparedStatement.executeBatch(OraclePreparedStatement.java:12369) | at org.jboss.resource.adapter.jdbc.WrappedStatement.executeBatch(WrappedStatement.java:517)INFO 26-09 14:20:28,584 (Log4JLogger.java:info:94) -closing | INFO 26-09 14:20:28,584 (Log4JLogger.java:info:94) -Running hbm2ddl schema export | DEBUG 26-09 14:20:28,584 (Log4JLogger.java:debug:84) -import file not found: /import.sql | INFO 26-09 14:20:28,584 (Log4JLogger.java:info:94) -exporting generated schema to database | DEBUG 26-09 14:20:28,584 (Log4JLogger.java:debug:84) -drop table Assay cascade constraints | | at org.hibernate.jdbc.BatchingBatcher.doExecuteBatch(BatchingBatcher.java:58) | at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:242) | ... 27 more View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3974189#3974189 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3974189 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
