Eclipse does not recognize content of persistence.xml

Question

Im getting the following error in eclipse:

The persistence.xml file does not have recognized content.

My persistence.xml file works great in my application but e

Answer 1

I had src/main/java/META-INF/persistence.xml working fine in Eclipse with embedded Tomcat. Because it was not being copied into the Maven-built WAR, I moved it to src/main/resources/META-INF.

Now src/main/resources/META-INF/persistence.xml won't validate.

If rename to xyz_persistence.xml, it validates fine.
If rename to persistence.xml, it fails to validate.

When these annoying situations arise, I often find numerous different "solutions" like mine, most of which are not universally applicable.

So, here's my "solution", which I think it a hack to get around a bug:

To remove the error "persistence.xml file does not have recognized content" error, disable the JPA Validator:

• List item Select menu item Project > Properties > Preferences > Validation
• List item Disable the JPA Validator for both Manual validation and Build validation.

You might need to clean and rebuild. Your mileage may vary.
