Subject [jira] [Created] (JCR-3584) Wrong handling of database 'schema' parameter causes NPE
Date Fri, 26 Apr 2013 14:20:16 GMT
Fabian Christ created JCR-3584:
----------------------------------

             Summary: Wrong handling of database 'schema' parameter causes NPE
                 Key: JCR-3584
                 URL: https://issues.apache.org/jira/browse/JCR-3584
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-core
    Affects Versions: 2.6
            Reporter: Fabian Christ


When configuring a MySQL persistence manager like this

<PersistenceManager class="org.apache.jackrabbit.core.persistence.pool.MySqlPersistenceManager">
  <param name="driver" value="com.mysql.jdbc.Driver"/>
  <param name="url" value="jdbc:mysql://host:3306/db"/> 
  <param name="user" value="user" />
  <param name="password" value="secret" />
  <param name="schema" value="mysql"/>
  <param name="schemaObjectPrefix" value="pm_ws_${wsp.name}_"/>
</PersistenceManager>

The parameter 'schema' should define the database schema. In the BundleDbPersistenceManager.java
of jackrabbit-core 2.6 we see this

312 	* Sets the database type. This identifier is used to load and execute
313 	* the respective .ddl resource in order to create the required schema
314 	* objects.
315 	* @deprecated
316 	* This method is deprecated; {@link setDatabaseType} should be used instead.
317 	*
318 	* @param databaseType database type name
319 	*/
320 	public void setSchema(String databaseType) {
321 	this.databaseType = databaseType;
322 	}

So setting the schema sets the databaseType. When setting the schema to anything different
from "mysql" you will get an NPE bebause the 'mysql.ddl' file can not be found when creating
the schema.
