Runtime Enhancement: Problems with Ant Task in Eclipse
Hello everybody,
I have got another problem. This time it is a problem with runtime enhancement.
I am enhancing my classes with the following ant script started from Eclipse:
<project name="jpa_enhance_builder">
<path id="enhance.cp">
<pathelement location="${basedir}${file.separator}bin"/>
<fileset dir="${basedir}${file.separator}lib/OpenJPA_1.2.1">
<include name="**/*.jar"/>
</fileset>
</path>
<path id="compile.classpath">
<fileset dir="${basedir}${file.separator}/lib">
<include name="**/*.jar"/>
</fileset>
<fileset dir="C:\GhostTO\workspace\XFTu\bin">
<include name="**/*.class"/>
</fileset>
<fileset dir="${src}">
<include name="**/*.class"/>
</fileset>
</path>
<property name="cp" refid="enhance.cp"/>
<property name="src" value="${basedir}${file.separator}src"/>
<property name="bin" value="${basedir}${file.separator}bin"/>
<target name="enhance">
<echo message="${cp}"/>
<taskdef name="openjpac" classname="org.apache.openjpa.ant.PCEnhancerTask">
<classpath refid="enhance.cp"/>
</taskdef>
<openjpac>
<classpath refid="enhance.cp"/>
<config propertiesFile="./src/META-INF/persistence.xml"/>
<fileset dir="${src}">
<include name="**/entities/*.java" />
</fileset>
</openjpac>
</target>
</project>
The build runs without any problems and with setting openjpa.Log = TRACE it seems that all classes are enhanced. But if I run my application, I still get the message:
Creating subclass for "[...]". 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.
Any ideas?
Can it be that Eclipse is somehow overwriting my enhanced classes on startup?

I tried to invoke it after a build, but the problem is that it is not invoked if I use CTRL + B or the corresponding menu items.
I just tried to delete all content from my binary folder and then starting a build, but this did not work either. Honestly, there are also no classes created. I can only generate classes by using the "Clean" command (that is why I invoked the Ant task after a "Clean").
For the case it could really be an Eclipse problem (actually seems so...): I am using Ganymede Eclipse 3.4.2
Thank you again for your answers :)

I don't think you want to invoke the script after a "Clean", my vauge
understanding is that would be used to clean up resources that Eclipse
wouldn't have cleaned up as part of a normal clean. In the blog posting, it
shows to invoke the enhancer script on a manual and auto build, have you
tried that yet?

Is it possible that your application is running off some classes(perhaps in
another jar) that you compiled previously before you setup the enhancer?

Re: Runtime Enhancement: Problems with Ant Task in Eclipse

Hi,
okay, this really makes sense. Even the Spring documentation says:
"Not all JPA providers impose the need of a JVM agent (Hibernate being an example). If your provider does not require an agent or you have other alternatives (for example applying enhancements at build time through a custom compiler or an ant task) the load time weaver should not be used."
So the warnings because of the missing LoadTimeWeaver really are just warnings and do not restrict the application, provided that the entities are already enhanced.
But even without any LoadTimeWeaver, lazy fetching does not work. Are there any OpenJPA settings I might have forgotten, or again some bad Spring configuration?
So far, I have my entityManagerFactory configured this way:
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitName" value="GhostTO" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.OpenJpaVendorAdapter">
<property name="database" value="MYSQL"/>
<property name="showSql" value="true"/>
</bean>
</property>
<property name="jpaDialect">
<bean class="org.springframework.orm.jpa.vendor.OpenJpaDialect"/>
</property>
</bean>
Greetings!
Naomi

Naomi-
I was thinking about this problem some more this morning and since you're
enhancing your Entities at build time, there isn't any reason to have a
Spring weaver configured. I did some digging around and found a forum post
regarding this very issue [1].

Hi Rick,
thank you so much for your time you spent!
Aww, I knew, that there was a time I did not have that enhance-message, but I thought I just imagined it ;)
I already used the InstrumentationLoadTimeWeaver some time before (that is why it was commented out in db.xml), but got warning messages that I had to use it with a Java agent. Because configuration examples for Spring and OpenJPA which I found in the internet used SimpleLoadTimeWeaver, I also did so.
Thanks to you I had a hint where the problem might be and could search more specificly and found this discussion:
https://issues.apache.org/jira/browse/OPENJPA-40
It seems that the LoadTimeWeavers provided by Spring have problems with the possible byte code enhancement at runtime (or something like that).
There is also an alternative "OpenJpaLoadTimeWeaver" attached, which just excludes the org.apache.openjpa package (don't know why this helps...). I could not find it in the Spring package where it should reside, so I just added the source to my project, and included it in my db.xml as LoadTimeWeaver.
Now it works without the error message but still I have another problem. I first thought it was because the classes are not enhanced / the error message, but as we found out, this is not the case:
I can not use lazy fetching for relations where I set the FetchType.LAZY. If I want to get the content of the specific attributes, I always get a null value (and there definitely should be any content).
Lazy fetching for attributes that where mapped with FetchType.EAGER but reached the MaxFetchDepth does not seem to be a problem.
Any ideas? ^^"

In your db.xml file you define a loadTimeWeaver property for bean

Hello everybody,
I spent the whole morning to create a new small project and could not make it work, too. Also here I get the error message.
I send you the project with this mail (hopefully this works with this mailing list).
I removed the libraries from the lib folder to not make the file that big. You need the following libraries in your classpath:
OpenJPA
(libraries have to be in the lib/OpenJPA_1.2.1 folder for the Ant script)
Spring
Commons Logging
Mysql Driver
JUnit / DbUnit / SLF4J
(I implemented a simple JUnit test with dbUnit Flatfile for testing, you also can implement your own tests without these three libraries)
I created the following model:
An Owner can own certain Kiosks. Documents can be sold by certain Kiosks and Kiosks can sell certain Documents. Available Documents are Newspapers or Magazines.
You need a MySQL database (myisam), which has the name "kioskdb" (do not forget to update the db settings in db.xml, persistence.xml and test.junit.AbstractTest). I think you can generate the DDL from the entities.
I implemented a simple JUnit test in package test.junit.KioskTest.
Today, I also tested the nightly build for enhancement and for application testing instead of the version 1.2.1 and there was also the error message, but additionally some messages for each of my entities of that type:
openjpa.Enhance - Type "class ..." is already persistence capable; skipping.
Strange, isn't it? O.o"

Naomi -
I'm stumped as well... I'd say start over with a new small project and see
if you can get that working. If you are unable to get the small project
working, you can post a zip for us and someone will look at it. I'm still
leaning toward an environment problem.

These are a sign that the classes have been enhanced. I'm stumped.
Perhaps someone could give you the location of the code inside openjpa
that checks to see if the classes have been enhanced. There might be a
bug there.

Re: Runtime Enhancement: Problems with Ant Task in Eclipse
Posted by Na...@gmx.de.
Hi,
so far, I just worked with one binary folder and did not create jars from the project, too. I checked the whole workspace and the eclipse classpath but did not find any double classes or imports. I even removed all classes from the binary folder and rebuilt them.
I debugged my application and had a look at the entity classes. They contain an pcDetachedState and a pcStateManager field. Is this a sign that the classes have been enhanced or do these fields also occur in unenhanced classes?

Perhaps there is a packaging issue. Is it possible that there are
multiple versions of the classes in your classpath when you run your
project?

Hey David,
thank you for the tip!
I checked one of my entities with javap:
1. After a clean and manually invoking the enhance task
2. After execution of my application
Both times the class has pc* methods, so it seems that they are enhanced and not overwritten by Eclipse.
So why the error message? :(

Hi Naomi,
Three easy ways to verify that your classes have been enhanced.
One install DJ Decompiler (Windows) or another decompiler and verify
that the class file is enhanced.
Two, run the JDK command:
javap -c <classname-without-dot-class>
and look for a bunch of methods with names that start with "pc".
Three, do a clean (unenhanced compile) and note file sizes.
Then do the enhancement step and expect to see a 4+ KB gain in file
sizes for enhanced files.
Once you can tell unequivocally whether a file is enhanced, I'm sure
you'll have luck troubleshooting the issue.
Cheers,
David

Hi Rick,
I also had that thought, but the message lists all of my entities, so I think they all have not been enhanced.
I oriented on the following tutorial for creating and invoking the build script:
http://webspherepersistence.blogspot.com/2009/04/openjpa-enhancement-eclipse-builder.html
I edited the XML to avoid setting and checking the arguments and additionally added my entities to the build path.
I also invoked the script on Eclipse's "Clean" process (does not make sense, I think, does it?) and I started it "manually" (right click on the enhance task and choosing "run as" - "Ant build").

Is it possible that only a portion of your Entities are being enhanced by the
build script? How are you invoking the ant build script?

Hello Donald,
thank you very much for your answer.
I already heard of that plug-in and would use it in case of doubt. But because of some security restrictions in my company also including Eclipse plug-ins, I would prefer an Ant solution to be able to hand-off the project without forcing everybody to install this plug-in.

Since you're using Eclipse, maybe taking a look at the experimental
Eclipse plugin for OpenJPA 1.2 would help?
