This sample illustrates how to create an IBM® WebSphere® Portlet Factory builder for calling REST style services, and then uses that builder in some sample models. The builder is part of the sample - it is not offered as a supported Portlet Factory builder.
Note: This sample is only for use in Portlet Factory version 6.0.1 or earlier. Starting in 6.0.2 there is a REST Service Call builder available in the product that should be used.
