[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-374) persistence.xml <jar-file> not following JSR220 spec

[Marco Dubbeld (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/EJB-374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32868#action_32868 ] 

Marco Dubbeld commented on EJB-374:
-----------------------------------

BTW that fix needs probably one or two extra lines, if it also needs to support absolute pathnames. 

But I am confused by the spec so please check the interpretation, I expect the jar files to be found in the classpath, not nested in the jar containing the persistence.xml. 

The spec says in 6.2.1.6: "Such JAR files are specified relative to the root of the persistence unit (e.g.,utils/myUtils.jar)" 
The spec says in 6.2.1.8, example 5: The order.jar is a jar file on the classpath containing another persistence unit,

> JSR220 says <jar-file> is relative to the root of the persistence unit, which is the place containing the META-INF/persistence.xml
> This is not the case. Instead, it looks for the jar relative to the JVM working directory. (see JarVisitorFactory.java)
> So providing an absolute file path in <jar-file> works, but not a relative path because the root changes changes based on the situation and environment.  E.g., the directory you run ant, when running tomcat, etc.
