Re: [eclipselink-users] EclipseLink 2: ANT Task Error

[Chuong Pham <chuonglepham@xxxxxxxxx>]

I tried this
"-Aeclipselink.persistencexml=website/WebContent/META-INF/persistence.xml"
and got this message:

    [javac] Note: Found Option : eclipselink.persistencexml, with value:
website/WebContent/META-INF/persistence.xml
    [javac] Note: The persistence xml file
[website/WebContent/META-INF/persistence.xml] was not found. NO GENERATION
will occur!! Please ensure a persistence xml file is available either from
the CLASS_OUTPUT directory [META-INF/persistence.xml] or using the
eclipselink.persistencexml property to specify its location. 
    [javac] Processor

javax.persistence.NamedNativeQueries, javax.persistence.Column,
javax.persistence.Table, javax.persistence.Id, javax.persistence.Entity,
javax.persistence.Lob, javax.persistence.GeneratedValue] and returns false.
    [javac] Round 2:

    [javac] warning: The following options were not recognized by any
processor: '[eclipselink.persistencexml]'

Which is strange as the persistence.xml for my project IS under
WebContent/META-INF/ folder so I don't know why I got the above message.

I also tried your second suggestion
"-Aeclipselink.persistencexml=file://D:/Project/website/WebContent/META-INF/persistence.xml"
and got this error message:

My project directory path is: D:\project\website\ and then the project
folders META-INF, resources, templates, WEB-INF under D:\project\website\. I
don't think it's a problem with the project structure as I am able to use
ANT and build my project successfully without EclipseLink model generator
directives. As soon as I use EclipseLink model generator, I get problems.

Do you have any other suggestions? If not, I'll log a bug with the
EclipseLink team for investigation.
