precedence of persistence.xml in hibernate project

I have an eclipse project with several jars for JPA / Hibernate. One of tham contains a META-INF/persistence.xml and I want to override that by defining my own persistence.xml. So I tried using my persistence.xml in src/persistence.xml also src/META-INF/persistence.xml but everytime it seems jar/META-INF/persistence.xml gets picked up. I also tried editing .classpath file of eclipse projects and moved up classpathentry path="bin" higher up than the library included but still its not picking up my persistence.xml

<classpath>
    <classpathentry kind="src" path="src/main/java"/>
    <classpathentry kind="src" path="src/main/rules"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
    <classpathentry kind="output" path="bin"/>
    <classpathentry kind="con" path="DROOLS/Drools"/>
    <classpathentry kind="con" path="org.eclipse.jdt.USER_LIBRARY/drools"/>
</classpath>

In the tutorial I read:

You will need to override these defaults if you want to change them, by adding your own persistence.xml in your classpath, preceding the default one in drools-persistence-jpa.jar

So I tried using my persistence.xml in src/persistence.xml also src/META-INF/persistence.xml but every time it seems jar/META-INF/persistence.xml gets picked up.

The persistence.xml should be located under META-INF/persistence.xml so the first attempt won't work. And when I look at your .classpath file, I don't see src as source path so the second attempt won't work either.

Try src/main/java/META-INF/persistence.xml instead.

Actually, your project layout really looks like a Maven layout and with Maven, resources typically go to src/main/resources or src/test/resources. But since you didn't mention what tutorial you're following, I can't confirm if this applies here.

Anyway, my suggestion should work.
