8.8. Initializing the Application Runtime Environment

To get your application up and running, there are some things you need to do every time the WAF

runtime starts up. Initializers exist to help you execute such code.

package com.example.binder;

import com.arsdigita.db.DbHelper;

import com.arsdigita.domain.DomainObject;

import com.arsdigita.domain.DomainObjectInstantiator;

import com.arsdigita.persistence.DataObject;

import com.arsdigita.persistence.pdl.ManifestSource;

import com.arsdigita.persistence.pdl.NameFilter;

import com.arsdigita.runtime.CompoundInitializer;

import com.arsdigita.runtime.DomainInitEvent;

import com.arsdigita.runtime.PDLInitializer;

import com.arsdigita.runtime.RuntimeConfig;

import org.apache.log4j.Logger;

/**

* Initializes the binder application.

* @see com.example.binder

* @author Justin Ross

public class Initializer extends CompoundInitializer {

private static final Logger s_log = Logger.getLogger(Initializer.class);

public Initializer() {

final String url = RuntimeConfig.getConfig().getJDBCURL();

final int database = DbHelper.getDatabaseFromURL(url);

add(new PDLInitializer

(new ManifestSource

("binder.pdl.mf",

new NameFilter(DbHelper.getDatabaseSuffix(database), "pdl"))));

}

public void init(final DomainInitEvent e) {

super.init(e);
