Hi,
I tried hibernate tools just to reveng database schema into ejb3 pojos.
I pointed two problems for the moment :

1. when I mapped timestamp into java.util.Calendar, I was unabled to have @Temporal annotation

2. The many-to-many problem, with the loop well known wich lead to bad execution

I try to solve it but not succeed for the moment.

1. For temporal problem, I recompiled beta9 sources with following code in EntityPOJOClass.java :

line 315 :
... else if ("timestamp".equals(typeName) || "java.sql.Timestamp".equals(typeName) || "java.util.Calendar".equals(typeName)) {
buildTemporalAnnotation( annotations, "TIMESTAMP" ); //..the default so don't generate
} ...

which is quit ugly, I agree but I works, so fine.

2. For the manytomany problem, it seems that indicating wich table is reverse would work. But I don't know how to specify this.
In reveng.xml property "invert" for many-to-one doesn't work.
And implementing custom strategy doesn't seem to give access to any helpfull method for such an information.
i'm a bit lost... any idea would be great

(if only i could have a beautyfull "false" for

if ( collection.isInverse() ) {

)

cheers,

thierry

I was not aware JPA temporal supported calendar?
Put a patch in jira.





From rev.eng.strategy:

/** is the collection inverse or not ? */
public boolean isForeignKeyCollectionInverse(String name, TableIdentifier foreignKeyTable, List columns, TableIdentifier foreignKeyReferencedTable, List referencedColumns);

/** is the collection lazy or not ? */
public boolean isForeignKeyCollectionLazy(String name, TableIdentifier foreignKeyTable, List columns, TableIdentifier foreignKeyReferencedTable, List referencedColumns);

Doesn't that help ?

I've tested and calendar works fine.
I'm not a patch expert, but if there is a procedure somewhere i can try.



Sure it helps, haven't seen it.
thx a lot.

just to signal that for java.util.Date, Temporal Type DATE is not generated too.
With TIMESTAMP for java.util.Calendar it could be a patch, but just you have a procedure to do this ? thx
