Now the question, which actually are two questions: A) CODETERM2 gives me error on Eclipse, and advises me to add a cast, but this doesn't solve the error.	o
I don't know if I must an annotation or any other additional thing to CODETERM3 B) As I have specified, the primery key is composed by 3 concepts, and CODETERM4 is required.	o
JPA modelling is ok, but I don't know how to do the same in NOSQL .	o
Well, you haven't said _which_ NoSQL engine you're going to, which is pretty important.	p
Most NoSQL data stores don't support the concept of a composite primary key - and some of them won't allow you unique columns in the first place.	o
First, note that I work for a NoSQL vendor, URL_http://gigaspaces.com/ [ URL_http://gigaspaces.com/ ] - I'm not unbiased.	o
However, going from JPA to NoSQL is not hard, no matter what your engine is.	o
For GigaSpaces, you can use JPA to talk to the data grid with very few changes, for example, although then you're still stuck with JPA.	o
To really think about JPA, you need to think about your data as _data_ and not organizational stuff; you have a triplet, basically, which means your NoSQL data items consist of three data items (predicate, subject, object, like you've used.)	o
For most NoSQL engines you'll probably want an id there, too, just for efficiency's sake.	o
The ID is the "primary key," and enforcing unique triplets after that is going to be on _your_ end more than the NoSQL engine's end; this is one area where NoSQL "suffers" compared to SQL, but it's also where you find the greatest speed and storage improvements.	p
For some NoSQL engines, then, you'll build a document, consisting of the three data items, and you'd just query for that document before writing it into the database.	o
I could give you an example for many NoSQL engines (and certainly can for GigaSpaces) but I don't know which one you're targeting or why.	o
Thank you for your explanation.	p
I am using Spring Data Graph, and the neo4j, and I have read that composed Id aren't allowed.	o
Your idea of having an Id is not exaclty what I need, because I need to prove that there are no equal triplets.	o
You'd have to start a transaction, run a query, update the data if the query fails, in that case.	o
Neo4J is okay, although obviously I prefer our own product.	p
:).	o
I can imagine... :) Thank you very much!.	p
Mujer, your domain looks like it would be much easier modelled in the graph database itself.	p
As it is RDF like triplets that are annotated here.	o
You are right in that Spring Data Graph right now does not support compound keys.	o
We will look into that in the future, but I can't promise anything.	n
In the graph you could model your nodes being Concepts (URIs) and the type of relationship representing what you want to represent with that Concept.	o
CODESNIPPET_JAVA1 .	o
This could be easily modelled with Spring Data Graph (or also with the pure Neo4j API) CODESNIPPET_JAVA2 .	o
The eclipse error is annoying but just a wrong visualization, the AspectJ team is in the process of fixing that.	o
Hope that helps, if you need further advice just ask Michael .	o
Have a look at Kundera.	o

PlayOrm is another solution which is JPA-like but with noSQL specific features like you can do @NoSqlEmbedded on a List of Strings and it is embedded in that row leading to a table where each row is a different length than the other rows...this is a noSql common pattern which is why NoSql ORM's need a slight break from JPA.	o

Alternative/compatible datastores for App Engine?	o
What other "nosql" databases are compatible (more or less) with the Google Appe Engine datastore.	o
Alternatively, what is a good abstraction layer/solution (free of charge) that abstracts between multiple database implementations including google app engine and my application for db access.	p
I'd like to develop an app for GAE but later deploy it on my own server, but I do not want to have to rewrite the db code.	o
Important Update: The app is developed in Java so ideally the Data Abstraction Layer or any alternatives must be "Java friendly".	p

AppScale 1.4 supports GAE 1.3.5's Java runtime (link in my answer).	o

I want to implement a tool in Java to learn more about cryptography.	o

I wanted to start my tool with some historical ciphers.	o

Thanks in advance.	o
To answer the question asked: javax.crypto deals with low level crypto: encryption, decryption, and hashing.	n
It's where the Cipher class is defined.	o
java.security deals with everything else: key management, certtificate management, and signatures.	o
Those interfaces abstract JCE providers, which implement specific algorithms.	o
Sun provides some, and BouncyCastle is another good one.	p
If you are planning some custom ciphers for which there is not already an implementation, you'll be implementing your own JCE provider, and specifically extending CODETERM1 .	o
It's not difficult, but you have to URL_http://java.sun.com/javase/6/docs/tech notes/guides/security/crypto/HowToImplAProvider.html [read-through-the- documentation-on-how-to-do-that] .	n
In order for the JCE to allow your provider, you will have to apply to Sun for a certificate, basically faxing them a signed statement that you are aware of the US export restrictions on crypto libraries.	o
It's a mix of the two packages.	o

Thanks.	o
But before further reading: Can you tell me if I can use this API to implement cryptogrphic algorithms which are not part of the JCA, yet.	o
E.g.	o
historical ciphers?	o
Thx.	o
JCA is just an API, it doesn't define ciphers.	o
The SPI (service provider interface) defines them, and you can extend the API to define your own.	o
You could take a look at URL_http://www.bouncycastle.org [The-Legion-of-the- Bouncy-Castle] .	o

The sun java security stuff was just too buggy to work in a compatible manner.	o
It should be compatible with itself, however.	o
