Persistence - how do I Make a plugin open anothers db

Can someone tell me how do I access a database of a plugin with other plugins ?
Here is the method that I want another plugin to use

Code:

    public void RemoveBounty(String ply) {
        PersistenceDataBase plyReg = OpenDataBase(ply);
    }

The OpenDataBase method is this one

Code:

    private PersistenceDataBase OpenDataBase(String ply) {
        PersistenceDataBase persistenceClass = plugin.getDatabase().find(PersistenceDataBase.class).where().ieq("playerName", ply).findUnique();
        if (persistenceClass == null) {
            persistenceClass = new PersistenceDataBase();
        }
        return persistenceClass;
    }

And this is how I declare the variable

Code:

    sdLaw plugin;

    public BountyHandler(sdLaw plugin) {
        this.plugin = plugin;
    }

When the 2nd plugin runs the method from the first I get a null error here:

Code:

plugin.getDatabase().find(PersistenceDataBase.class).where().ieq("playerName", 

 

Plugin 1 should provide an interface for plugin 2 to modify plugin 1's database. Plugin 2 should hook into plugin 1 and use this interface.

 

Mr. Plugin was dating Miss Plugin, but when Miss Plugin found Mr. Plugin digging in her lingerie drawer, she broke his jaw.

If a plugin's data should be accessible to another plugin, it should provide API functions. One plugin should never be directly accessing the data of another plugin.

 

Well the problem is here:

Code:

 PersistenceDataBase persistenceClass = plugin.getDatabase().find(PersistenceDataBase.class).where().ieq("playerName", ply).findUnique();

Then debugging I found that the second plugin.getDatabase() doesn't come with Ebean configuration...
That configuration only works if I'm using the first plugin to get the database.

Well I solved it, thank people =)
