Run BattooJPA against JPA Bench from http://www.jpab.org and post the results

http://www.jpab.org/ has a GPL tool for benchmarking JPA providers. I encourage you to post 'official' benchmark results. EclipseLink is the current winner: I'd love to see how you guys stack up!

ManagedList is not serializable

ManagedList is not serializable and therefore serialization fails if you store entities in ViewScoped/SessionScoped beans.

IdClass does not work as expected

Hi,

using @IdClass in one of our entiy beans produces the exception "org.acme.test.BeanPK does not have a corresponding embeddable type."
The id-class BeanPK is not annotated with any annotations.

class BeankPK {
String name;
String key;
...
}

@entity
@IdClass(BeanPk.class)
class Bean {
@id name;
@id key;
...
}

The same code is working fine in hibernate and should work accoring to JPA-spec 11.1.19 and 2.4

Downgrade asm to 3.3.1

ASM 4.0 is fairly new and conflicts with a number of frameworks.

Downgrading to 3.3.1 is the solution.

Document the new feature Slow SQL

Implement Pluggable Datasource Inlets

A Plugabble datasource implementation that will:

Take a class name to be instantiated by means of reflection with constructor of Map<String, String> param
That will pass settings in means of java beans reflection

i.e.:

batoo.datasource.com.jolbox.bonecp.class= com.jolbox.bonecp.BoneCPDatasourceProxy
batoo.datasource.com.jolbox.bonecp.statementsCacheSize= 50
batoo.datasource.com.jolbox.bonecp.releaseHelperThreads= 0
(...)

@JoinColumn(name) is ignored

ManyToOneTest has the failure...

Test Sample App with Weblogic 10.x

Implement DB2 JDBC Adaptor

Prepare the website

Use BoneCP as the datasource manager

Would it be possible to allow pluggable ConnectionPools in the future?
As we use BoneCP in all projects (and we are very happy with it!), this would be a great feature.

[perf] Avoid for each loops on ArrayList

A for-each on ArrayList creates unnecessary AbstractList$Itr instances.
This can be avoided if index-based loops will be used.

This was also done is some apache projects:
https://issues.apache.org/jira/browse/MYFACES-3130

I could also change it and provide a pull request :)

[perf] Avoid for each loops on ArrayList [2]

I will provide a patch tomorrow.

If you have a idea how to optimize

ManagedList line 192

and replace the iterator loop with a index based loop in

PluralAssociationMapping line 573

we only have aroud 15k iterator instances anymore.

900k vs 15k should be a great performance boost.

Create JDBC Update DDL Type

Empty predicates generate wrong SQL

If i pass a empty predicate array to criteriaBuilder#and, wrong SQL will be generated.

Restore Pretty SQL Logging Facility that is lost after switching to BoneCP

Batoo + Postgre schemas + @Table annotation

When I use @table anotation on an entity class, it was created sucessfull, but when i try to make any query, the generated SQL doesn't contains the schema prefix.

Postgre 9.1
Glassfish 3.2
Batoo 0.1.3

@Id @ManyToOne attribute will be handled as basic attribute

A attribute with @id and @manytoone will be handled as BASIC attribute in 0.1.3:

@Id
@ManyToOne
@NotNull
@JoinColumn(name = "entity2Id", nullable = false)
private Entity2 entity2;

ParentMapping#createMapping reads the attribute#getPersistentAttributeType() and this returns PersistentAttributeType#BASIC for this attribute.

QueryDSL like API

As far as I understand the goal was to have JPA compliant ORM implementation.
I guess since BatooJPA is JPA compliant I can use http://www.querydsl.com/ just on top of BatooJPA. But since this adds another layer of abstraction (and sometimes defects) on top of existing ORM I am wondering if it will add some additional overhead in terms of performance.

Have you considered proving proprietary API for more elegant querying? It would make BatooJPA not only the fastest but the easiest to use as well.
