[andreapi87]

int id2=pageDao.getIdByTitle("Category:Islamic terrorism",simple,NameSpace.CATEGORY);
Collection categoryList = localCategoryMemberDao.getCategoryIds(en, id2);

for(Integer e: categoryList)
{
System.out.println(e);
System.out.println(pageDao.getById(simple, e));
}

gives me
33049350
LocalPage{nameSpace=CATEGORY, title=Category:Islam and violence (en), localId=33049350, language=English}
16702064
LocalPage{nameSpace=CATEGORY, title=Category:Islamic fundamentalism (en), localId=16702064, language=English}

18501425
LocalPage{nameSpace=CATEGORY, title=Category:Religious terrorism (en), localId=18501425, language=English}

watching into the db:
