I am getting very frustrated with an JPA mapping, please help!
I have several words lists: GMAT, SAT etc. Same word can appear in
many different list. The words list has description, creator etc.
In java, I have a class called WordList which contain a collection of
words. Can anyone shred some idea on how to do it properly? I
navigate from List to Word.
----------------------
I am doing following, which seem terrible for something so simple. I
am sure there must be a better way:
1: WordList_Word_Mapping: save mappingId and WordId (gae does not
support jointable)
2. Word: underlying word, has no information about words list
When user want to find all word in a list, I have to do following:
1. query the Mapping to find all keys for word (using listname)
2. using the wordKey to construct a string like ('key1','key2')
3. query word using IN ('key1','key2')
Thanks.
