Overview

EasyJMS (SuperMessaging) is a J2EE tool as a JMS (Java Message Service) client for J2EE server, using reliable, asynchronous, loosely coupled communication.

• It provides a GUI explore to show JNDI based information about JMS in the system, for both regular Queue, Topic and Message Driven Beans.
• It provides a facility for sending messages visually, for both Queue and Topic. Message cases can be exported to SuperScheduler and SuperWatchdog as JMS jobs.
• It provides a facility for building trigger and export to SuperWatchdog as JMS trigger.
• Messages and triggers are customizable by using APIs.

It is a monitor and management tool. No programming is required. Your keyboard is necessary if you want input values for poking.

EasyJMS supports JMS 1.1 specification.

EasyJMS is formerly called SuperMessaging. Only the commercial name is changed. The internal name is still SuperMessaging.

Prerequisite

See Prerequisite in Installation for general prerequisite.

Destination

EasyJMS supports JMS 1.1 specification: EasyJMS uses common interfaces that enable both Queue and Topic. The way to use EasyJMS is not specific to either Queue or Topic. Support for JMS 1.1 is mandatory for all J2EE 1.4 certified J2EE servers.

EasyJMS is based on JNDI. EasyJMS works directly on the target destination, either Queue or Topic. The consumer or comsumers of the destination can be a J2EE application client, standalone client or a Message Driven Bean.

Dynamic message

EasyJMS is a general purpose tool. It provides a easy way to specify a text message. No programming is required. But if your message is an ObjectMessage or other type of message, or your message is dynamic in the nature, you can use DynamicMessage. In that case, you need to implement your own class.

To use DynamicMessage, you need to create your class implementing this interface. The implemented class must have a constructor with empty parameter. The constructor may be called more than once.
 

Dynamic message filter

EasyJMS is a general purpose tool. When a JMS trigger is constructed, as default, there is no message filter. It listen all messages from the destination (Queue or Topic).

If you want to filter our unwanted message, you can use DynamicMessageFilter. In that case, you need to implement your own class.

To use DynamicMessageFilter, you need to create your class implementing this interface. The implemented class must have a constructor with empty parameter. The constructor may be called more than once.

Message selector

EasyJMS is a general purpose tool. When a JMS trigger is constructed, as default, there is no message filter. It listen all messages from the destination (Queue or Topic).

If you want to filter our unwanted message, you can message selector, which is defined by JMS specification. Please see JMS specification, or the document from your J2EE server for detailed information.
