Enhancing entities: getting desperate
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.

Re: Enhancing entities: getting desperate
Posted by Michael Dick <mi...@gmail.com>.
Enabling trace when you run the enhancer should print a list of the classes
as they are enhanced.
Try adding the following to persistence.xml :
<property name="openjpa.Log" value="Enhance=TRACE"/>

You are right, I'm not running with Java2 Security.

Rick, Kevin: Many thanks, adding the librabry to the classpath did the
trick. I'm finally able to actually use OpenJPA now.
The fact that it goes through all the librabry classes used elsewhere, is
this also the reason why the enhancement process takes quite some time to
finish?
At first I was affraid that it that enhancer was enhancing all class files,
not just the classes to persist, because of the access requirement of other
libraries and the time it takes to enhance. I assume that this isn't the
case? Is there a way to check which classes are/where actually enhanced?

Re: Enhancing entities: getting desperate
Posted by Kevin Sutter <kw...@gmail.com>.
Hi Prodoc,
The call stack indicates that we are attempting to process the Access Type
for a Method (Field or Property).
enhance:
java.lang.NoClassDefFoundError: org/w3c/dom/svg/SVGDocument
at java.lang.Class.getDeclaredMethods0(Native Method)
at java.lang.Class.privateGetDeclaredMethods(Class.java:2427)
at java.lang.Class.getDeclaredMethods(Class.java:1791)
at
org.apache.openjpa.lib.util.J2DoPrivHelper$9.run(J2DoPrivHelper.java:305)
at java.security.AccessController.doPrivileged(Native Method)
at
org.apache.openjpa.persistence.PersistenceMetaDataDefaults.getAccessType(PersistenceMetaDataDefaults.java:265)
Here's the code snippet from getAccessType (I'm assuming a 1.2.x OpenJPA
code base):
if (annotated((Method[]) AccessController.doPrivileged(
J2DoPriv5Helper.getDeclaredMethodsAction(cls))).size() > 0
|| cls.isInterface()) // OpenJPA managed ifaces must use prop
access
access |= ClassMetaData.ACCESS_PROPERTY;
return getAccessType(cls.getSuperclass()) | access;
The doPrivileged call is used for Java2 Security permission checking. If
you are not running with Java2 Security enabled, then this turns into
"noise". I'm assuming you are not running with Java2 Security.
As you can see, we need to get access to the declared methods of the given
Class. And, we will recursively call this method to go up the Class
heirarchy. It would seem that something in your Entity definition is using
this org/w3c/dom/svg/SVGDocument Class. Either directly or indirectly.
And, as Rick has pointed out, this Class would need to be available for the
PCEnhancing process to be successful.

Re: Enhancing entities: getting desperate
Posted by Rick Curtis <cu...@gmail.com>.
It would appear that the class org.w3c.dom.svg.SVGDocument isn't on the
classpath when you run the enhancer.

Re: @Version annotated Field not included in SELECT (prepstmnt)
Posted by Craig L Russell <Cr...@Sun.COM>.
Hi Heiko,
<jpa spec p. 383>
The following types are supported for version properties: int,
Integer, short, Short, long,
Long, Timestamp.
</jpa spec>
Try changing the type of the version field and see if that helps.
If so, please file a JIRA to give an error message instead of a silent
fail.
Thanks,
Craig

@Version annotated Field not included in SELECT (prepstmnt)
Posted by it...@daimler.com.
Hello,
I'm having an issue in openJPA 1.2.1 with a entity model as follows:
@Entity
@Table(name = "PARTNER", schema = "PART")
@NamedQuery(name = "getPartner", query = "SELECT p FROM Partner p where
p.partKey = :partKey")
public class Partner
{
@Id
@Column(name = "PART_KEY")
private BigDecimal partKey;
@OneToMany(mappedBy = "partner", fetch = FetchType.LAZY)
private List<PartnerRolle> rollen;
}
@Entity
@Table(name = "PARTNERROLLE")
public class PartnerRolle
{
@EmbeddedId
private PartnerRolleKey key;
@Version
@Column(name = "VERSION")
private BigDecimal version;
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "PART_KEY")
private Partner partner;
}
When I ask for a Partner and later on call getRollen(), in the
corresponding SELECT (prepstmt), the Column VERSION of PARTNERROLLE is NOT
queried (not listed in the SELECT). When I remove the @Version annotation,
it works corerctly, thus the VERSION is filled with the correct value. It
only works as expected, when I do NOT set @Version to that column.
I doubt this is correct behaviour, cause even though its a simple query,
ALL annotated columns should be returned, whether or not they changed. I
was relying on the return of the VERSION field and ran into a
NullPointerException because the BigDecimal was not correctly instatiated.
Any suggestion, even if it is "this is correct behaviour, because ..."
would be appreciated.
Thanx,
Best regards,
Heiko

Fixed now. A simple later calling of the enhance target did the trick.
I'm now back at the 'NoClassDefFoundError' error. Any idea what the cause of
this could be?

Re: Enhancing entities: getting desperate
Posted by Prodoc <ag...@hobba.nl>.
Darn, I shouted too soon...
I just performed a clean and with the same build config as mentioned in my
last post I now get presented with a different error:
java.lang.IllegalArgumentException: java.lang.ClassNotFoundException:
mpsf.entities.EngagementRange
It appears to have worked before because I did a compile without the
enhancer. I just don't understand why getting enhancement to work is so
troublesome. I suspect that I'll be prented with the error in the previous
e-mail again as soon as I manage to fix this one.

Thanks for your reply Michael. Yes, I do have all the entities included in
persistence.xml except for all the embeddables.
After further investigation I found that the enhance target was never
processed because I didn't know I had to call it from elsewhere in the build
files *hits head against desk*. I now get the enhancer to run but I had to
deal with serveral issues afterwards ('MetaDataFactory could not be
configured', 'java.lang.ClassNotFoundException', etc.). I feel that I'm
slowly getting closer to get it to start enhancing but I'm stuck with one
more problem.
The build.xml file now contains the following:
-------------------------------------------------------------------------------------------------
<path id="jpa.enhancement.classpath">
<pathelement location="build/classes"/>
<fileset dir="lib/apache-openjpa-1.2.1">
<include name="**/*.jar"/>
</fileset>
</path>
<target name="enhance">
<taskdef name="openjpac"
classname="org.apache.openjpa.ant.PCEnhancerTask">
<classpath refid="jpa.enhancement.classpath"/>
</taskdef>
<openjpac>
<config propertiesFile="./src/META-INF/persistence.xml"/>
<fileset dir=".">
<include name="**/src/mpsf/entities/*.java">
</fileset>
<classpath refid="jpa.enhancement.classpath"/>
</openjpac>
</target>
-------------------------------------------------------------------------------------------------
The error I'm now presented with is:
-------------------------------------------------------------------------------------------------
enhance:
java.lang.NoClassDefFoundError: org/w3c/dom/svg/SVGDocument
at java.lang.Class.getDeclaredMethods0(Native Method)
at java.lang.Class.privateGetDeclaredMethods(Class.java:2427)
at java.lang.Class.getDeclaredMethods(Class.java:1791)
at
org.apache.openjpa.lib.util.J2DoPrivHelper$9.run(J2DoPrivHelper.java:305)
...
-------------------------------------------------------------------------------------------------
Any idea what this could be?
Yours,
Age

Re: Enhancing entities: getting desperate
Posted by Michael Dick <mi...@gmail.com>.
Hi,
Do you have all your entities listed in persistence.xml? The exceptions
below look like the list is either missing, or doesn't have a complete list
of your entities.
