[jira] Created: (OPENJPA-1491) org.apache.openjpa.kernel.Bootstrap
uses the application classloader to load OpenJPA internals
org.apache.openjpa.kernel.Bootstrap uses the application classloader to load OpenJPA internals
----------------------------------------------------------------------------------------------
Key: OPENJPA-1491
URL: https://issues.apache.org/jira/browse/OPENJPA-1491
Project: OpenJPA
Issue Type: Bug
Components: integration
Affects Versions: 2.0.0-beta
Environment: OSGi
Reporter: Timothy Ward
When attempting to create an EntityManagerFactory in an OSGi environment the org.apache.openjpa.kernel.Bootstrap class attempts to instantiate a BrokerFactory using reflection. When the Bootstrap class attempts to load this class it only ever uses the ClassLoader passed in by the PersistenceUnitInfo. This means that the default broker (contained within OpenJPA) can never be loaded. The client bundle should not have to import the internals of OpenJPA to make this work, so OpenJPA should attempt to load the class using its own bundle classloader. This is the expected behaviour for an OSGi bundle.
Additionally, the implementation uses Class.forName() which should be avoided in an OSGi envrionment (to see why read http://blog.bjhargrave.com/2007/09/classforname-caches-defined-class-in.html ).
The following exception is generated when OpenJPA attempts to use the application classloader to load an internal class.
<openjpa-2.0.0-SNAPSHOT-r422266:905001 fatal user error> org.apache.openjpa.persistence.ArgumentException: Could not invoke the static newInstance method on the named factory class "<<openjpa-2.0.0-SNAPSHOT-r422266:905001 fatal user error> org.apache.openjpa.util.UserException: The named BrokerFactory "org.apache.openjpa.jdbc.kernel.JDBCBrokerFactory" is not valid.>".

------------------------------------------------
Well, I'm not too sure. I'm using Felix Karaf which does not come with JPA. I'm using OpenJPA to provide both API and implementation of JPA.
To be clear on the top of Karaf, I'm putting those bundles:
+ OpenJPA Aggregate Jar (2.0.0)
+ Apache Geronimo JSR-317 JPA 2.0 Spec API (1.0)
+ Commons Collections (3.2.1)
+ Commons Lang (2.5)
+ Commons Pool (1.5.3)

org.apache.openjpa.kernel.Bootstrap uses the application classloader to

This fix only applies to OSGi environments where Apache Aries JPA 0.1-incubating is being used.
Are you trying to run OpenJPA as an OSGi bundle? If so, are you using Apache Aries in a custom assembly or the latest Apache Geronimo 3.0-SNAPSHOT builds?
To be more specific - OpenJPA does not include support for the OSGi Enterprise Specification r4 v4.2 section 127 JPA Service Specification, but relies on Apache Aries JPA (http://incubator.apache.org/aries/jpaproject.html) which wrappers OpenJPA to deliver that support.

[jira] Updated: (OPENJPA-1491) org.apache.openjpa.kernel.Bootstrap
uses the application classloader to load OpenJPA internals
Posted by "Timothy Ward (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/OPENJPA-1491?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Timothy Ward updated OPENJPA-1491:
----------------------------------
Description:
When attempting to create an EntityManagerFactory in an OSGi environment the org.apache.openjpa.kernel.Bootstrap class attempts to instantiate a BrokerFactory using reflection. When the Bootstrap class attempts to load this class it only ever uses the ClassLoader passed in by the PersistenceUnitInfo. This means that the default broker (contained within OpenJPA) can never be loaded. The client bundle should not have to import the internals of OpenJPA to make this work, so OpenJPA should attempt to load the class using its own bundle classloader. This is the expected behaviour for an OSGi bundle.
Additionally, the implementation uses Class.forName() which should be used carefully in an OSGi envrionment (to see why read http://blog.bjhargrave.com/2007/09/classforname-caches-defined-class-in.html ). It should be fine here because the variant that takes a ClassLoader is used.
The following exception is generated when OpenJPA attempts to use the application classloader to load an internal class.
<openjpa-2.0.0-SNAPSHOT-r422266:905001 fatal user error> org.apache.openjpa.persistence.ArgumentException: Could not invoke the static newInstance method on the named factory class "<<openjpa-2.0.0-SNAPSHOT-r422266:905001 fatal user error> org.apache.openjpa.util.UserException: The named BrokerFactory "org.apache.openjpa.jdbc.kernel.JDBCBrokerFactory" is not valid.>".

Jean-Philippe CLEMENT commented on OPENJPA-1491:
------------------------------------------------
Issue seems closed and fixed in v2.0.0, but I experience this problem in the v2.0.0 relase:
