Error: No persistence.xml file in project [message #434876]

Hi,

I'm using Dali 1.0.2 (latest release available, apparently), and followed
the "Create New JPA Project wizard" (from the Getting Started guide)
several times now to try to get everything working correctly. I'm able to
generate entites, but I keep getting this error: "No persistence.xml file
in project", even though Dali auto-generated it into src/META-INF. Any
ideas? I've even tried moving the META-INF dir directly under the project
folder, as I saw in another online guide, but it still can't seem to find
persistence.xml.

Note: in the wizard I have selected "Annotated classes must be listed in
the persistence.xml", and left "Create orm.xml" unchecked. I'm using
OpenJPA as my provider.

Thanks,
Ari

Ari,

Take a look at the org.eclipse.wst.common.component file in your
project_home/.settings folder. There should be a source-path defined.
Perhaps you could post the contents of that file.

This isn't something we have encountered in our own testing, so I am
interested to figure out what might be going wrong.

Hi Neil,

Here it is:

<?xml version="1.0" encoding="UTF-8"?>
<project-modules id="moduleCoreId" project-version="1.5.0">
<wb-module deploy-name="P2V3_JPA">
<wb-resource deploy-path="/" source-path="/src/main/java"/>
<wb-resource deploy-path="/" source-path="/src/main/resources"/>
<wb-resource deploy-path="/" source-path="/src/test/java"/>
</wb-module>
</project-modules>

Also, I'm using Maven with the Eclipse plugin to configure my Build Path
-- not sure if that's a problem, since it alters my .classpath.

Best,
Ari

Ari,

I think this explains the problem. Your src/ folder is not in the source
path, so we don't see the persistence.xml in meta-inf. Add another
source-path for /src/ and that should fix it.

<wb-resource deploy-path="/" source-path="/src"/>

Yep, that did it! I think this should be documented, particularly since
this source path folders are often changed by developers. Considering
Maven's popularity, perhaps Dali could offer at least the option of
using Maven's conventions, like having META-INF under
/src/main/resources when generating these files.

Thanks for the help!
