Re: [ANN] OpenJPA Maven Plugin 1.0 Released

I am using toolProperties to specify the persistence.xml and persistence unit.

The syntax:

<toolProperties>
  <property>
    <name>properties</name>
    <value>
  ${build.testOutputDirectory}/META-INF/persistence.xml#OpenJpaTest
    </value>
  </property>
</toolProperties>
means "use the persistence-unit 'OpenJpaTest' in the file persistence.xml", where 'OpenJpaTest' is what I named the XML persistence-unit node in the file - and I have several in one persistence.xml. 

I have seen it mentioned on the openjpa list:

http://article.gmane.org/gmane.comp.apache.openjpa.user/3499

where it is done like this on the command line (for javaagent - different, I 
know):

-javaagent:C:/eclipse.workspaces/3.2.2/openjpa-1.2.0/openjpa-all/target/openjpa-1.2.0.jar=pu=OpenJPAPU

The code from svn gave this exception:
<openjpa-1.2.0-r422266:683325 fatal user error> org.apache.openjpa.util.MetaDataException: MetaDataFactory could not be configured (conf.newMetaDataFactoryInstance() returned null). This might mean that no configuration properties were found. Ensure that you have a META-INF/persistence.xml file, that it is available in your classpath, or that the properties file you are using for configuration is available. If you are using Ant, please see the <properties> or <propertiesFile> attributes of the task's nested <config> element. This can also occur if your OpenJPA distribution jars are corrupt, or if your security policy is overly strict. at org.apache.openjpa.meta.MetaDataRepository.initializeMetaDataFactory(MetaDataRepository.java:1567) at org.apache.openjpa.meta.MetaDataRepository.endConfiguration(MetaDataRepository.java:1558) at org.apache.openjpa.lib.conf.Configurations.configureInstance(Configurations.java:505) at org.apache.openjpa.lib.conf.Configurations.configureInstance(Configurations.java:430) at org.apache.openjpa.lib.conf.PluginValue.instantiate(PluginValue.java:103) at org.apache.openjpa.conf.MetaDataRepositoryValue.instantiate(MetaDataRepositoryValue.java:68)

but if I try specifying the persistence-unit name some other way, e.g. as a toolProperties property 'pu', it ignores me and throws this exception (OpenJpaTest was the one I was aiming for):

So basically you need to get that persistence-unit name to the PCEnhancer or it looks like it processes all the persistence-units.

Hi!

@Randy, txs 4 the patch, good catch.

As I also commented in JIRA: A few points are still open

1.) using a different configuration XML (other than persistence.xml) should
be provided as own plugin attribute (and not in the 'additional properties'
list).

2.) using a different configuration XML must also work for the openjpa:sql
and openjpa:schema mojos.

I will implement this after I'm back from vacation next week.

@Adam: Can you please checkout the latest from SVN and try it with this
version?

svn co https://svn.codehaus.org/mojo/trunk/mojo/openjpa-maven-plugin

Do you have other wishes? So we can plan to make a 1.1 with ~ end of march.

txs and LieGrue, strub

Februar 2009, 5:38 Mark/Adam,
I have filed a JIRA ticket with a patch for this issue: http://jira.codehaus.org/browse/MOJO-1309 

I am not sure why Adam is specifying the 'properties' property, but we use
it to ensure the enhancement is processing based off of a specific project
persistence.xml file... there are multiple persistence.xml files on the
classpath. I feel this is a fairly important bug to fix since I think it is
generally a regression from the 1.0-alpha version.

HTH,

Adam,

For what I've seen the 'properties'

property specifies a file which contains the configuration.
So I'm honestly a bit confused about the value: META-INF/persistence.xml#OpenJpaTest 

Can you please tell me what you like to achieve and

how your config file really looks like (including real filename).


Please note that the ant tasks imho calls the

PCEnhancer only via spawning an own java cmd. So any error occurring may
not get to your eyes there.

Any idea what it could be, seeing that extra #null on the end of the 
persistence filename?
