LocalContainerEntityManagerFactoryBean could accept "classpath*:/" path locations [SPR-3979]

[spring-projects-issues]

Leonardo Pinho opened SPR-3979 and commented

LocalContainerEntityManagerFactoryBean could use PathMatchingResourcePatternResolver as ResourcePatternResolver and allow to use classpath*:/ location paths to read jar-file from persistent.xml, like:

<persistence>
<persistence-unit name="SpringJpaPersistenceUnit" transaction-type="RESOURCE_LOCAL">
<jar-file>classpath*:/common.jar</jar-file>
</persistence-unit>
</persistence>

Otherwise, we have to use the xml above in order to read some jar ("common.jar" p.ex.) from WEB-INF/lib:

<persistence>
<persistence-unit name="SpringJpaPersistenceUnit" transaction-type="RESOURCE_LOCAL">
<jar-file>/WEB-INF/lib/common.jar</jar-file>
</persistence-unit>
</persistence>
Thanks,
Leonardo

Any comment? :)

The problem here is that common.jar is not technically a classpath resource: Its contents are part of the classpath but it cannot be found on the classpath itself.

The idea is still not bad... Maybe we can find some other solution for jar file scanning there.

"classpath*:" URLs won't work here, but standard location patterns such as "/WEB-INF/lib/*.jar" should work in most environments (provided that the web container makes jar files visible as ServletContext resources). I've added that capability for Spring 2.5.1.
