Cannot instantiate persistence manager org.apache.jackrabbit.core.persistence.pool.MySqlPersistenceManager

问题

I have deployed Jackrabbit 2.6.4 in Glassfish 4 using jackrabbit-jca-2.6.4.rar.

Everything works when I use the following configuration (Derby via JDBC):

    <PersistenceManager class="org.apache.jackrabbit.core.persistence.pool.DerbyPersistenceManager">
      <param name="url" value="jdbc:derby:${wsp.home}/db;create=true"/>
      <param name="schemaObjectPrefix" value="${wsp.name}_"/>
    </PersistenceManager>

but when I switch to this (Mysql via a datasource):

    <PersistenceManager class="org.apache.jackrabbit.core.persistence.pool.MySqlPersistenceManager">
      <param name="url" value="jdbc/MySQLDataSource"/>
      <param name="driver" value="javax.naming.InitialContext"/>
      <param name="schemaObjectPrefix" value="${wsp.name}_"/>
    </PersistenceManager>

I have configured a Mysql JDBC Connection Pool and JDBC Connection Resource (jdbc/MySQLDataSource) in Glassfish and placed mysql-connector-java-5.1.26-bin.jar in the domain/lib directory. I can successfully ping the database via the Glassfish JDBC Connection Pool page in the Admin UI.

Am I missing something in the JackRabbit PersistanceManager configuration?

UPDATE 1

If I don't use my datasource and instead use a JDBC URL in my PersistanceManager configuration to connect to the database it works as expected.

回答1:

It turns out that the Mysql JDBC connection pool was not configured correctly.

In order to get it to work I had to set the following properties:

User
Password
DatabaseName
ServerName
Url
URL

I also had to repeat the database and server name in the Url and URL fields e.g.

jdbc:mysql://127.0.0.1:3306/db_name

At this point I'm not sure why there is a Url and a URL property but setting both of them to the above URL worked.
