Hi,
I don't know what I'm doing wrong but I can't seem to get OpenJPA to work in
my project. I keep running into entity enhancement issues. The more methods
I try, to more problem it seems to be causing.
*Using*
- NetBeans 6.5.1
- Java jdk1.5.0_16
- OpenJPA 1.2.1
- Derby 10.5.1.1
*Structure*
- MPSF
- lib
- apache-openjpa-1.2.1
- src
- META-INF
- mpsf
- entities
- build.xml
If I leave 'RuntimeUnenhancedClasses' set to 'supported' I get the following
error:
-------------------------------------------------------------------------------------------------
297 MPSFPU INFO [AWT-EventQueue-0] openjpa.Runtime - Starting OpenJPA
1.2.1
875 MPSFPU INFO [AWT-EventQueue-0] openjpa.jdbc.JDBC - Using dictionary
class "org.apache.openjpa.jdbc.sql.DerbyDictionary".
2187 MPSFPU INFO [AWT-EventQueue-0] openjpa.Enhance - Creating subclass
for "[class mpsf.entities.SearchDetection, class mpsf.entities.RotationRate,
class mpsf.entities.Weapon, class mpsf.entities.Sensor, class
mpsf.entities.TrackDetection, class mpsf.entities.Environment, class
mpsf.entities.Trainer, class mpsf.entities.EngagementRange, class
mpsf.entities.KillProbability, class mpsf.entities.TimeOfFlight, class
mpsf.entities.Threat]". This means that your application will be less
efficient and will consume more memory than it would if you ran the OpenJPA
enhancer. Additionally, lazy loading will not be available for one-to-one
and many-to-one persistent attributes in types using field access; they will
be loaded eagerly instead.

-------------------------------------------------------------------------------------------------
Why do I get errors like 'The type "class mpsf.entities.SearchDetectionPK"
has not been enhanced.' while OpenJPA is supposed to be subclassing the lot?
Because I want to have the entities enhanced on a later stage anyway I
decided to deal with that right away in the hope to get things to work in
the first place. I set 'RuntimeUnenhancedClasses' to 'warn' and tried the
enhance at build time using ANT approaches. At least this got my program to
run in the first place but things are going wrong as soon as I try to
actually access the db. I'm always getting the following error using
different ANT configuration ways:
-------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------
The entity I try to use is 'Threat'. In the error above it states
'mpsf.Entities.Threat'. I tried both 'Threat' and 'mpsf.Entities.Threat',
the latter incase I had to specify the packages but it didn't make any
difference.
First attempt in build.xml:
-------------------------------------------------------------------------------------------------
<target name="enhance">
<taskdef name="openjpac"
classname="org.apache.openjpa.ant.PCEnhancerTask"/>
<openjpac>
<fileset dir=".">
<include name="**/entities/*.java" />
</fileset>
</openjpac>
</target>
-------------------------------------------------------------------------------------------------
After some reading up [1] I got to the following with different inbetween
attempts in the hope to get a cleaner result then this:
-------------------------------------------------------------------------------------------------
<path id="jpa.enhancement.classpath">
<pathelement location="bin"/>
<fileset dir="lib/apache-openjpa-1.2.1">
<include name="**/*.jar"/>
</fileset>
</path>
<target name="enhance">
<copy includeemptydirs="false" todir="bin">
<fileset dir="src" excludes="**/*.launch, **/*.java"/>
</copy>
<taskdef name="openjpac"
classname="org.apache.openjpa.ant.PCEnhancerTask">
<classpath refid="jpa.enhancement.classpath"/>
</taskdef>
<openjpac>
<classpath refid="jpa.enhancement.classpath"/>
</openjpac>
</target>
-------------------------------------------------------------------------------------------------
All attempts just result in the same: none of the entities get enhanced,
never are there any known entity names.
The mentioned website does include an additional 'depends="build"' attribute
in the target element but doing so results in a different error: 'Target
"build" does not exist in the project "MPSF". It is used from target
"enhance".'
What is it that I keep doing wrong? What does it take to get the entities
enhanced?
I hope you can help me out.
Yours,
Age Bosma
P.s. As you might have figured, I'm new to JPA and ANT.
