You can access the request attributes in the message data either programmatically or by using an expression language.
The expression language uses expressions similar to XML Path Language (XPath) expressions to access the parts of the message data. If you use an expression language, you must add the corresponding tag libraries to the user-defined JavaServer Pages (JSP) document.
The message attribute contains the message. The message can be a commonj.sdo.DataObject object or a primitive type.
This attribute represents the message content as a map. The keys of the message map are strings that represent XPath expressions to access the leaf nodes of the business object. The values in the map are the string representations of the data values of the business objects. When applicable, these values are the result of a locale sensitive conversion in Business Process Choreographer Explorer according to the locale that is specified in the browser. For example, the numerical value that represents the process state is converted into a string.
This attribute accesses the validation errors from a submitted form. The value is a map that maps the XPath expression for accessing the incorrect property to the validation message.
