Hi Lars,
I unzip the file and ran it. I was able to run PCEnhancer but failed to
execute your Main.java for the following error message:
Exception in thread "main" <openjpa-1.1.0-SNAPSHOT-runknown nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: An error occurred while parsi
ng the query filter "select m from MYAPPLICATION.PEOPLETABLE m". Error message:
The name "MYAPPLICATION.PEOPLETABLE" is not a recognized entity or identifier. P
erhaps you meant Person, which is a close match. Known entity names: [Person]
I then changed your query in Main.java to:
Query q = em.createQuery("select m from Person m");
It then works fine. The attached is my run.bat to set classpath, compile entity
classes, and run PCEnhancer, and execute Main.java.

Subject: Re: Could not locate metadata (orm.xml)
Hi Fay,
yes both are in the same directory. I tried with and without mapping entry in
persistence. For reference I attached the content of my source directory. It is
a very tiny example
If someone wants to test this, please run Main.java.
Best regards, Lars
2008/3/31, Fay Wang <[EMAIL PROTECTED]>:Hi Lars,
I ran your example as a standalone one. and the PCEnhancer works for me.
Here is my persistence.xml:
<persistence-unit name="person">
<provider>com.ibm.websphere.persistence.PersistenceProviderImpl</provider>
<mapping-file>META-INF/orm.xml</mapping-file>
<class>datamodel.Person</class>
<properties>
<property name="openjpa.jdbc.DBDictionary" value=""/>
...
and my orm.xml:
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/ormorm_1_0.xsd";
version="1.0">
<entity class="datamodel.Person">
<table name="MYAPPLICATION.PEOPLETABLE"/>
<attributes>
<id name="id" />
<basic name="firstName" />
<basic name="lastName" />
<transient name="nonsenseField" />
</attributes>
</entity>
</entity-mappings>
They are almost identical as yours. Did you put your orm.xml in the same
directory as your persistence.xml?

Hi Fay,
I don't get the meaining of your comment. Are you saying my example works
for you? Are you running it standalone or inside a web container? Best
regards, Lars
