Eclipse Plugin for OpenJPA
Hi,
For Eclipse IDE users, a plugin is available to help development with
OpenJPA [1]. It adds a builder step to Java projects in Eclipse workspace so
that all your persistent classes are bytecode enhanced as part of the
Eclipse's incremental compilation process.
Please note that, at this point, this plugin is in very early stage of
development and is not part of official OpenJPA release or maintenance.

Hi Daryl,
> Pinaki, I'm sure your plugin will be great,
Thank you for your kind words. But I am really a novice in such matters.
> but FYI I have added this as a feature request to the MyEclipseIDE plugin
What is the status of this request?
Please note that while implementing this plugin, I found understanding of
certain aspects of classloading disciplines by serp (the additional utility
that really edits the bytecode) is essential. The classloading is somewhat
more involved because of a generic plugin of this nature must be able to
'see' the user's entity classes. By default, such visibility does not exist
because Eclipse loads respective plugin in their own classloader. I read
about a 'buddy scheme' that Hibernate plugins used to circumvent similar
visibility issue. This plugin, however, follows a different approach by
constructing classloaders dynamically as a combination of user project's
classpath and openjpa library classpath while loading user's domain classes
for enhancement.
Please convey to MyEclipseIDE that they are welcome to contact us if they
need further details to help their development.

Pinaki, I'm sure your plugin will be great, but FYI I have added this as a
feature request to the MyEclipseIDE plugin that I use that has support for
OpenJPA.

If you are saying we should make this stuff part of openjpa officially
(meaning some new openjpa-eclipse module) then I have some concerns.
I am not conversant with the complexity of build process and dependencies in
automating maven builds for such plugin -- but my assumption is it is going
to be non-trivial. Also it will bring dependencies with other (jdt) eclipse
plugins that may be evolving faster than our current dependencies such as
Apache Commons libraries.
Hence, my preference is to consider a separate project altogether. Such
project will have more independence to reach a skill set focused towards
Eclipse plugin development and IDE usability aspects.

Hi,
I am still in the process of figuring out how to build this stuff without
the help of Eclipse PDE.
Will get the legal issues surely sorted out once we get the mechanics right.

No need to go through the incubator to create a tooling sub-project for
OpenJPA. Maybe 'sub-project' is not quite the right term here, but the
point is that the OpenJPA team can carve out svn space to develop and
maintain OpenJPA Eclipse tooling and you can package/release that stuff
however you see fit (usual caveats apply). No need for incubator foo here...

Re: Eclipse Plugin for OpenJPA
Posted by Pinaki Poddar <pp...@apache.org>.
Hello Craig,
In this thread we are discussing possible options for hosting a Eclipse
plugin for OpenJPA. Most of the responses so far seem to suggest a
sub-project for OpenJPA. A sub-project that will will not tie down/alter
main OpenJPA project's build or release processes.
Will you please comment what is a good option for hosting such a plugin
development? And if we go for a sub-project, what procedural steps, if any,
needs to be taken up with Apache Board?

Pinaki

No idea. It had already been created before I started working on Geronimo.
From the ASF page -
http://www.apache.org/foundation/how-it-works.html#incubator
it sounds like sub-projects should go through the incubator, so maybe we
should just create a branch for tooling under the existing openjpa
project and just handle it just as another OpenJPA binary release with
its own JIRA component for bug/feature tracking and not deal with the
sub-project process overhead for now.

Re: Eclipse Plugin for OpenJPA
Posted by Donald Woods <dw...@apache.org>.
For Geronimo, we also setup a Devtools subproject for our Eclipse
plugins. I would suggest doing that for OpenJPA, as the maven builds
are different enough that you don't want non-Eclipse users to deal with
the delays of downloading an Eclipse runtime for the build steps. Also,
you may want to release the tooling more or less often than a given
branch(es) or support different levels of Eclipse with different
versions of the plugins.

Re: Eclipse Plugin for OpenJPA
Posted by Pinaki Poddar <pp...@apache.org>.
Hi Kevin,
Why I considered starting to build a plugin for OpenJPA is two-fold:
a) to estimate and experience first hand, what is the complexity involved in
developing a Eclipse based tooling for OpenJPA with this prototype. Starting
as a novice, the effort was equivalent to 4 person-days.
b) I have seen too many questions and doubts and reports that are related to
enhancement in one way or other. Making enhancement a transparent (or
perhaps even invisible) part of compilation process will remove/lower a
barrier to wider adoption of OpenJPA.
At this point, I have not pondered about future of this activity. All that
I know is tooling is a high-priority item and the competitors are ahead. We
should better get started. And the best help is often at the end of one's
own arms :)
I am open to any suggestions to collaborate with other people with similar
interests. And perhaps i am slightly less clueless about Eclipse plugins
than I was a week ago to participate in such collaborative efforts :)
Regards and if you are a Eclipse user, be kind enough to give this plugin
a try.

Hi Pinaki,
Thanks for starting this activity. I've noticed that OpenEJB has a separate
project for the OpenEJB Eclipse Plugin. Maybe we should consider following
the same path? Not sure if it's a lot of overhead to have a separate
project like that or not.
Thoughts?

Pinaki, can we at least get a copy of the current plugin source checked
into openjpa/sandboxes, until we decide on how to build/release it?
If you don't have time to check-in the files, just send me a tar/zip and
I'll work on it.

I am also trying to use this plugin as an exemplar for openjpa-contrib [1].
Hence, I will add a openjpa-contrib module (without any dependency to our normal builds).
Then create a openjpa-contrib/eclipse -- and donate the code underneath in standard src/main/java directory structure. Based on your experience with Genonimo Eclipse plug-ins, feel free to modify that structure, if needed.
After researching on how maven can build a plugin that can also be used in Eclipse PDE environment -- which turned out to be non-trivially complex -- I am considering whether Ant will be the right tool for this purpose.

Pinaki, have you had the chance to upload the current source code
anywhere? Can you place it under -
http://people.apache.org/~ppoddar/eclipse/
and I'll login and grab it from my account on p.a.o?

Re: Is setQueryCache() broken, and how to fix?
Posted by Michael Dick <mi...@gmail.com>.
Hi Joe,
I'd say this is a bug.
OpenJPAQuery q = OpenJPAPersistence.cast(em.createQuery("Select p from
Person p");
q.setQueryCacheEnabled(false); // should behave identically to disabling
the query cache in the config.
I'm not terribly familiar with that part of the code, but if you're
interested in pursuing the problem I'll try to help.

Is setQueryCache() broken, and how to fix?
Posted by Joseph Weinstein <jo...@oracle.com>.
Hi all, I am starting my climb to being able to fix OpenJPA bugs,
and would like anyone's opinion on a case I want to fix or at least
explain.
My current problem involves a case where the application code wants
no query cache, and causes setQueryCache(false) to be called, reaching
class
org.apache.openjpa.jdbc.kernel.JDBCFetchConfigurationImpl
Note that QueryCache is set to true in the properties file. Then the
code executes a query, and during the query, and during it's processing
I nevertheless see caching:
[java] at org.apache.openjpa.datacache.ConcurrentQueryCache.putInternal(ConcurrentQueryCache.java:124)
[java] at org.apache.openjpa.datacache.AbstractQueryCache.put(AbstractQueryCache.java:115)
[java] at org.apache.openjpa.datacache.DelegatingQueryCache.put(DelegatingQueryCache.java:124)
[java] at org.apache.openjpa.datacache.QueryCacheStoreQuery$CachingResultObjectProvider.checkFinished(QueryCacheStoreQuery.java:561)
[java] at org.apache.openjpa.datacache.QueryCacheStoreQuery$CachingResultObjectProvider.next(QueryCacheStoreQuery.java:593)
[java] at org.apache.openjpa.lib.rop.EagerResultList.<init>(EagerResultList.java:35)
[java] at org.apache.openjpa.kernel.QueryImpl.toResult(QueryImpl.java:1219)
[java] at org.apache.openjpa.kernel.QueryImpl.execute(QueryImpl.java:987)
[java] at org.apache.openjpa.kernel.QueryImpl.execute(QueryImpl.java:796)
[java] at org.apache.openjpa.kernel.QueryImpl.execute(QueryImpl.java:766)
...
If I totally turn off caching in the config, we use a
org.apache.openjpa.jdbc.kernel.InstanceResultObjectProvider
being used, not a QueryCacheStoreQuery...
So how should the no-cache state in JDBCFetchConfigurationImpl
have reached/affected the query processing?
thanks in advance for your expertise,

Can you check the source into the OpenJPA sandbox, so others can help
setup the builds/legal files before we import it into a real branch?
