Configure jackrabbit with jndi

Question

I'm trying to configure jackrabbit's file system and persistence manager through jndi as follows (repository.xml):

<PersistenceManager class="org.apache.jackrabbit.core.persistence.bundle.MSSqlPersistenceManager">
    <param name="driver" value="javax.naming.InitialContext"/>
    <param name="url" value="java:/jdbc/MY_DATASOURCE/default"/>
    <param name="schema" value="mssql"/>
    <param name="schemaObjectPrefix" value="jcr_pm_"/>
</PersistenceManager>

<FileSystem class="org.apache.jackrabbit.core.fs.db.DbFileSystem">
    <param name="driver" value="javax.naming.InitialContext"/>
    <param name="url" value="java:/jdbc/MY_DATASOURCE/default"/>
    <param name="schema" value="mssql"/>
    <param name="schemaObjectPrefix" value="jcr_fs_"/>
</FileSystem>

when I start my server I get the following exception:

16:34:09,209 INFO  [STDOUT] 2013-12-03 16:34:09,205 ERROR [org.apache.jackrabbit.core.fs.db.DbFileSystem] failed to initialize file system

the version of jackrabbit is 1.4 jackrabbit does not seem to like jndi configuration. I also tried with url=jdbc/MY_DATASOURCE/default but i get the same error
