Quartz di JAVA Web

Bisa dibilang ini lanjutan tulisan tentang quartz, g ribet, Cuma menurut gw sih penting. Soalnya potensi untuk terus dipake cukup gede, dimana bisa dipake untuk back-end aplikasi web.
Intinya, sebenarnya gimana make quartz diintegrasiin sama JAVA Web, mungkin solusi lain ya kita bikin aplikasi terpisah pake quartz, Cuma kebetulan lagi proyek yang desain back end nya otomatis jalan pas JAVA Web nya running.

Teknologi yang digunakan:

Eclipse Indigo
JAVA 7 Update 79
Quartz 2.2.3

Jar yang digunakan:

c3p0-0.9.1.1.jar
log4j-1.2.16.jar
quartz-2.2.3.jar
quartz-jobs-2.2.3.jar
slf4j-api-1.7.7.jar
slf4j-log4j12-1.7.7.jar
jta-1.1.jar –> ini googling sendiri ya.

Contoh Class untuk job quartz

package sample.quartz;
 
import org.quartz.*;
 
public class SampleQuartzScheduler implements Job {
	@Override
	public void execute(JobExecutionContext arg0) throws JobExecutionException {
		System.out.println("Sample Quartz Scheduler");		
	}
}

Untuk detail konfigurasi quartz nya, langsung ke website resminya aja kali ya .
