Membrane Service Proxy

is an reverse HTTP proxy and framework written in Java, licensed under the ASF 2.0 Open Source License, that can be used to:

  • create service proxies out of SOAP and REST services
  • integrate services over HTTP
  • expose internal services to the internet
  • secure services
  • convert Web Services to REST resources

Follow the SOAP and REST tutorials or have a look at the examples to get started.


Hosting virtual REST services is easy:

			<serviceProxy port="80">
				<target host="www.thomas-bayer.com" />

By default SOAP proxies configure themselves from WSDL:

			<soapProxy wsdl="http://thomas-bayer.com/axis2/services/BLZService?wsdl">

A console shows all details of the configuration, statistics and recent requests:

Follow the SOAP Quick Start Guide to learn how to use a soapProxy, XML Schema validation and SOAP Stack Trace Filtering.

What's new in 3.5

Using the default configuration, there is a new "Calls" tab in the admin console. You can inspect the latest requests and responses that passed through Membrane. You can filter and sort by many criteria, and drill down to inspect every detail of each request.

Using the new SOAP Explorer (automatically activated by using soapProxy) together with the new index interceptor (an overview of all proxied services), clients can comfortably browse the available Web Services, look at the list of operations, investigate data structures and retrieve templates for SOAP requests.
