In the PersistenceMappingDefault.populateJoinColumn() method, it missed the call to validate the column length. Consequencely the column length that was longer than DB2's max column length resulted an invalid column length exception .
The fix wil be:
public void populateJoinColumn(FieldMapping fm, Table local, Table foreign,
Column col, Object target, int pos, int cols)
{
// only use spec defaults with column targets
if (!(target instanceof Column))
return;
// if this is a bidi relation, prefix with inverse field name, else
// prefix with owning entity name
FieldMapping[] inverses = fm.getInverseMappings();
String name;
if (inverses.length > 0)
name = inverses[0].getName();
else
name = fm.getDefiningMapping().getTypeAlias();
// suffix with '_' + target column
name += "_" + ((Column) target).getName();
name = dict.getValidColumnName(name, foreign); ===> add this call before set the name to the column.
col.setName(name);
}
