custom datasource factory in tomee.xml with factory-name having arguements

[ereshgorantla]

HI ,
I am configuring datasources in tomee.xml using Resources. 
Initially I did like this ...
<tomee>
<Resource id="TestPoolDataSource" type="DataSource">
                DataSourceCreator   tomcat
            DriverClassName  oracle.jdbc.OracleDriver
            Url jdbc:oracle:thin:@$DB_URL$
            UserName    $USER$
            Password    $PWD$
            JtaManaged  true
            InitialSize $DB_INITIAL_CAPACITY$
                MaxActive   $DB_MAX_CAPACITY$
            TestOnBorrow        true
            TestOnReturn        false
            ValidationQuery      select 1 from dual
            ValidationQueryTimeout 30
            RemoveAbandoned true
            RemoveAbandonedTimeout 600
            LogAbandoned true
            SuspectTimeout 60
            TimeBetweenEvictionRunsMillis       30000
            MinEvictableIdleTimeMillis  30000
            TestWhileIdle       true
        </Resource>
</tomee>

Then there is a need to configure custom datasource  factory . So my
tomee.xml chnaged to 

<tomee>
<Resource id="TestPoolDataSource" type="DataSource"
factory-name="getObjectInstance"
            class-name="TomcatDataSourceFactory">
            
        </Resource>

</tomee>

But factory-name getObjectInstance has arguments in it . How can we pass
those values.
public class TomcatDataSourceFactory extends BasicDataSourceFactory {
public Object getObjectInstance(Object obj, Name name, Context nameCtx,
Hashtable environment) throws Exception {
<-------custom code ----->
return super.getObjectInstance(obj,name,nameCtx,environment);

}
}

Unlike if resource is congigured in context/server.xml . if factory class is
specified , datasource is configured directly no need to specify . How can
we achieve this functionality in tomee.xml.
Either ways like passing arguments to Customdatasource factory/directly
calling factory class . 
Please provide your comments.
