WebSphere ESB 602: Message Element Setter

In the first of a series of posts on the new functionality coming up in WebSphere Enterprise Service Bus 6.0.2, I’d like to introduce one of our new mediation primitives: the Message Element Setter.

The job of this primitive is to provide you with an easy way to set a particular part of the message with a value. Previously, the only way to do this would be to utilise the XSLT primitive with a very simple XSLT function, or to use a custom mediation primitive. Both of these are pretty heavyweight for such a simple job, and so the Message Element Setter was born.

Very simply, you can configure the primitive to set any part of the Service Message Object, specified via an XPath, with a value of a particular type. In addition, there are two special types of setter: the copy and delete. Copy allows you to copy part of the SMO from one place to another, and delete obviously allows you to delete the value of the part of the SMO you specify.
