This document discusses configuration patterns in Mule, including simple service, web service proxy, bridge, validator, and HTTP proxy patterns. The simple service pattern exposes components like POJOs, JAX-WS services, and JAX-RS services as request-response services. The web service proxy pattern proxies remote web services and can transform SOAP envelopes. The bridge pattern establishes a direct connection between an inbound and outbound endpoint and supports transformations and transactions. The validator pattern validates inbound messages against filters and returns ACK/NACK responses. The HTTP proxy pattern sits between a caller and target resource, propagating HTTP requests and responses. Configuration patterns are designed for ease of use over power for common tasks.
