> I hope the @SecondaryTable in supperclass,example:
> @MappedSuperclass
> @SecondaryTable(name=".." ..)
> public B extends A {
> }
> @MappedSuperclass
> public C extends B {
> }
> @Entity
> public D extends C {
> }
> @Entity
> public C extends C {
> }
> but query("select o from C where .."), the join is correct.i correct:
> openjpa-jdbc\src\main\java\org\apache\openjpa\jdbc\meta\FieldMappingInfo.java
> /**
>      * Return the join from the field table to the owning class table.
>      */
>     public ForeignKey getJoin(final FieldMapping field, Table table,
>         boolean adapt) {
>         // if we have no join columns defined, check class-level join
>         List cols = getColumns();
>         if (cols.isEmpty()) {
>     			cols = field.getDefiningMapping().getMappingInfo().
>     						getSecondaryTableJoinColumns(_tableName);
>     			if (cols.isEmpty()) {
>     				for (ClassMapping scm = field.getDefiningMapping().getPCSuperclassMapping();

>     						scm != null; 
>     						scm = scm.getPCSuperclassMapping()) {
>     					
>     					cols = scm.getMappingInfo().getSecondaryTableJoinColumns(_tableName);
>     					if (!cols.isEmpty())
>     						break;
>     				}
>     			}
>     		}
