Compiling
I'm interested in hacking on OpenJPA a little. I downloaded the nightly
snapshot, but it doesn't compile on a fresh install of maven:

What can I do to get a compiling version?
Re: Compiling

So, I've spent a few hours digging into adding support for INSERT RETURNING,
and I give up. Here is why:
1. The architecture used to generate SQL is all over the place.
Sometimes SQL is generated in DBDictionary classes. Sometimes it is
generated in RowImpl and who knows where else. This makes it very hard to
customize generated SQL based on DB features.
2. The same is true for processing the results of generated SQL. Why
isn't this all in the same place so its overridable on a DB by DB level?
3. Public variables
4. Protected variables
5. Lack of generics in 1.5 projects (openjpa-persistence-jdbc)
6. StringBuffer in non-threaded areas of 1.5 projects
(openjpa-persistence-jdbc)
7. A lot of strings seem to be regenerated over and over again. I
could be wrong, given 1.
8. Lots of magic strings. I expected this when generating SQL, but
when throwing exceptions? throw new
SQLException(_loc.get("update-failed-no-failed-obj",
String.valueOf(count[i]), _batchedSql).getMessage());
Are there plans to fix any of this?

The optional RETURNING clause causes INSERT to compute and return value(s)
based on each row actually inserted. This is primarily useful for obtaining
values that were supplied by defaults, such as a serial sequence number.
However, any expression using the table's columns is allowed. The syntax of
the RETURNING list is identical to that of the output list of SELECT.
That should prevent the need for the SELECT CURVAL('seq') query after
inserting a row. It saves you one SQL statement per insert. Technically
its also useful for other things, but thats the biggest thing I can think
of.

Hi,
Inserts are handled by ClassMappings and their FieldMappings and
associated strategies.
What does INSERT RETURNING do? Can you describe how you want to
utilize it from OpenJPA?

I'm pretty much lost in the source code. I'm looking for the piece who's
job it is to run inserts. I'm specifically wondering whether it would be
possible for OpenJPA to take advantage of Postgres's INSERT RETURNING
clauses.

Yeah, that's because OpenJPA's JDBC wrappers don't have the Java 6
methods in them. If we added them, OpenJPA would not be able to
compile on Java 5...
Note that you can use the JAVA_VERSION env variable to tell mvn to try
to use Java 5:
$ JAVA_VERSION=1.5 mvn test
