 Description  « Hide
This simple orm.xml file causes a NPE -

<?xml version="1.0" encoding="UTF-8"?>

<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/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd"
    version="1.0">

  <package>springdeveloper.domain</package>

  <entity class="Client" metadata-complete="false" access="FIELD"></entity>
  <entity class="Manager" metadata-complete="false" access="FIELD">
    <attribute-override name="description">
      <column name="DESCR" length="2000"/>
    </attribute-override>
  </entity>

</entity-mappings>

I have attached a test case - plainJpa.zip

Same code runs fine with the RI.

This is the output from my run:

The error message is a bad one (which I've committed a fix for), but the cause of it is that the orm.xml file is in error: as I mentioned in OPENJPA-40, the attribute-override element is, AFAIK, only meant to be used to redfine a field declared in a superclass entity. Since Manager doesn't actually have any Entity superclass, OpenJPA's assumption was causing an NPE. A better error message will now be thrown.

You are right about the <attribute-override> - got to read the spec more carefully :)

I have been testing the recent MVN version 442043. I can run without an orm.xml file included but as soon as I include some additional mappings in an orm.xml file I get errors.

Here is some recent output:

This is the command I use to execute:

Hmm ... the ClassCircularityError should have been resolved by my fix for OPENJPA-40. Can you make sure you re-built and deployed the built jars to your Spring installation? Just to be sure, you may want to update to the latest svn revision (442386).

If it still fails, can you attach a new test case (just like the one for OPENJPA-40) and I'll try to reproduce?

Marc,

I saw your fix for the circular reference and I don't see the error message right now after checking out the latest (now at rev. 442412). I'm getting an error building, but the jars seem to be created anyway. This is the last part of the build messages:

Anyway, I still get an exception executing my test - see attached zip file. Is this related to OPENJPA-44 since I do use the "metadata-complete" attribute?

I'm surprised by the build error ... I haven't seen it before. However, I agree that it sounds like the jars are being built OK.

As for the "Could not locate metadata for the class.." error, that means that OpenJPA didn't load the class for some reason. If you change your query to query the full class name (e.g., change "select x from Manager x" to "select x from org.mypackage.Manager x"), do you get the same error? A better error message might result.

Also, if you want to attach the new test case, I can take a look.

Marc,

I did attach a test case - OPENJPA-32.zip

This is the output and mapping files - fully qualified name did not work either.

persistence.xml:

We've committed a number of fixes to the class loading framework when using the class transformer, which appears to make this work.

Note, though, there are some errors in your orm.xml: you didn't declare the <mapped-superclass class="Person"/>, and you put overridden attributes in the <attributes> section, rather than the <attribute-override> section (which the spec mandates). I'll attach the corrected orm.xml to this report.

Corrected orm.xml file.
