Subject OpenJPA with AriesJPA Java.peristence
Date Thu, 10 May 2018 19:08:59 GMT
Hello,

I am running Karaf 4.2.0, trying to setup a project with OpenJPA.  I am getting error:


14:44:07.799 ERROR [FelixDispatchQueue] FrameworkEvent ERROR - org.apache.aries.jpa.container

This looks like version mismatch.  I am loading the following packages in my feature:

	<feature>aries-blueprint</feature>
	<feature>war</feature>
 	<feature>camel-core</feature>
	<feature>camel-servlet</feature>
	<feature>camel-blueprint</feature>
	<feature>camel-jackson</feature>
	<feature>jndi</feature>
	<feature>jdbc</feature>
	<feature>transaction</feature>
	<feature>jpa</feature>
	<feature>openjpa</feature>
	<feature>pax-jdbc-mariadb</feature>
        <feature>pax-jdbc-config</feature>


One thing I don’t know if is correct is the javax.persistence dependency in my POM:

	<dependency>
            <groupId>org.eclipse.persistence</groupId>
            <artifactId>javax.persistence</artifactId>
            <version>2.0.5</version>
            <scope>provided</scope>
        </dependency>

Any hints?

Best regards,
Alex soto
