1.2 Web Service consumer SOADIAGEchoConsumer service invocation

Write a simple jsp file like the following one:

This is not the normal way to invoke a Web Service in aJSP file since it breaks the struts layout.

Moreover it does not handle exceptions.

2 Publish/Subscribe summaryReminder

A publish/subscribe Web Service SOADIAGEchoEvent isdefined in SOAREPO, we will:

- Provide a publisher of this event

2 Event EDA SOADIAGEchoEventEvent publisher/subscriber

SOADIAGEchoEvent is an event Web Service, also knownas oneway

The same wizard is used for code generation but the

semantic is inversed:

Consumer wizard is used to publish a message

Provider wizard is used to subscribe a message

The configuration is slightly different since MQ JMS isused instead of HTTP
