Nous rencontrons un problème lors de l'exécution d'une portlet dont les services de données ont été générés avec service builder.

Une erreur est produite: 14:27:40,342 ERROR [JDBCExceptionReporter:101] ORA-00904: "SLRDOCUMEN0_"."SLR_DOC_TYP_SUB_TITLE" : identificateur non valide

Le nom de la table est mystérieux .. il ne correspond à rien et à aucune des définitions de service.xml !

at slr.comment.service.persistence.SlrDocumentTypPersistenceImpl.findAll(SlrDocumentTypPersistenceImpl.java:455)
at slr.comment.service.persistence.SlrDocumentTypPersistenceImpl.findAll(SlrDocumentTypPersistenceImpl.java:391)

Le code généré dans ces classes par service builder, notamment les chaînes de caractères avec les instructions SQL ne semblent pas être bizarres a priori.

Est-ce un problème connu ?
Comment est-il possible de déterminer la cause du problème et corriger ?

Merci pour votre aide !

I think that SB truncated your original table from SlrDocumentTyp and did a little bit of renaming to come up with the unique SLRDOCUMEN0_

In my own SB code, sometimes I have had to go back and edit the SQL generated in docroot/WEB-INF/sql/tables.sql to adjust types and sizes. And other times I've had to adjust the hibernate mapping files generated in docroot/WEB-INF/src/META-INF/portlet-hbm.xml in order to resolve some java type issues, but I don't remember getting an exception about an invalid identifier...

If you wouldn't mind posting the relevant snippets from your service.xml and portlet-hbm.xml files, I might be able to help you with this...

Sorry my response is in english, but I used babelfish to translate your question so I could help and my French is very rusty emoticon

Thank you David for you response.

I also created a thread in the english forum : http://www.liferay.com/community/forums/-/message_boards/message/8808546 and opened an issue LPS-17219.
All project code and scripts to create the database are available attached to the issue LPS-17219.

Note that i disabled table autogeneration in service-ext.properties (build.auto.upgrade=false). The schema is already created with our own scripts. We are using a customized datasource (i mean we are not using lportal).

indexes.sql, sequences.sql and tables.sql are empty in WEB-INF/sql and I think it is normal (I like that).

Hibernate definitions seem ok to me also:

I finally found the problem after i set log level DEBUG for org.hibernate. It was my error but i was confused by the name of the table in the error message.

Here is the generated SQL statement

20:16:42,288 DEBUG [SQL:111] select * from ( select slrdocumen0_.SLR_DOCUMENT_TYP_ID as SLR1_274_, slrdocumen0_.SLR_DOC_TYP_LABEL as SLR2_274_, slrdocumen0_.SLR_DOC_TYP_MAIN_TITLE as SLR3_274_, slrdocumen0_.SLR_DOC_TYP_SUB_TITLE as SLR4_274_, slrdocumen0_.SLR_DOC_TYP_DESC as SLR5_274_ from SLR_DOCUM
ENT_TYP slrdocumen0_ order by slrdocumen0_.SLR_DOC_TYP_LABEL ASC ) where rownum <= ?

My entity
<entity name="SlrDocumentTyp" table="SLR_DOCUMENT_TYP" local-service="true" data-source="slrDS" session-factory="slrSF" tx-manager="slrTX">
...
</entity>

I was surprised by the table name but it is correct after i have seen the SQL statement ... the problem was a mistyping in the column definition for the column SLR_DOC_TYP_SUB_TITLE !!!!

My fault ... but it was confusion without the sql statement displayed together with the error.
