Quartz Minimal Demo Websphere + Tomcat

Minimal project for demonstrate Quartz scheduler in Websphere and Tomcat environment.

• Quartz by default uses SimpleThreadPool which runs scheduled jobs outside J2EE context.
• Project uses thread pool wrapper and runs threads with server context via work managers, JSR 237, with access to resources via JNDI.
• Runs on both Tomcat and Websphere containers with same source base, same build (war).
• Includes Tomcat alternative resource configuration (DataStore, Url, WorkManager) to websphere's resourcers.

Setup

Compile: gradle clean build Eclipse: gradle cleanEclipse eclipse Prereq:

• Oracle DB 11g
• Gradle 3.4

Setup DB:

1. Create Scheduler tables DBscripts\tables_oracle.sql

Setup Websphere:

1. Create resources (Datastore, Url, WorkManger) References to resources are bind by WEB-INF/ibm-web-bnd.xml (only Websphere needs bindings definition, Tomcat ignores this) Scheduler starts on http://localhost:10039/quartz-minimal/

Setup Tomcat:

1. Copy jars from tomcat/libs to <TOMCAT_HOME>/libs Resources configuration are defined in META-INF/context.xml (only Tomcat use this configuration, Websphere ignores this) Scheduler starts on http://localhost:8080/quartz-minimal/

External libs for Tomcat:

• foo-commonj-1.1.0.jar, commonj-twm.jar (JSR 237 Timer and WorkManager implementation, used in tomcat) http://commonj.myfoo.de/download.shtml
• resource-factory-0.1.jar (URL provider implementation, used in tomcat)
• ojdbc6.jar (driver for Oracle DB)

Tested environments:

• Quartz 2.2.3
• Websphere 8.0.0.5
• Tomcat 7

Quartz on Websphere

Websphere requires threadPool and threadExecutor to runs thread via WorkManager, see sk.fillo.quartz.ManagedThreadPool and sk.fillo.quartz.ManagedThreadExecutor.

Quartz on Tomcat

Tomcat requires to Quartz jobs must be wrapped by commonj Work with setup deamon to true, see sk.fillo.quartz.WorkAdapter.
