Lightweight Web Services Monitoring and Governance
predic8 offers open source tools that help to run a successful SOA.
Membrane SOAP Monitor
Captures, displays and manipulates SOAP messages. The XML beautifier makes it easy to analyze even complex messages.
Membrane SOA Registry
Lightweight registry that observes Web Services to insure a healthy SOA. Monitors and logs the availability of services. If a WSDL description of a service has changed the registry will detect the change.

Protocol Buffers, Etch, Hadoop and Thrift Comparison (15.04.)
This article compares some popular frameworks which are used for object serialization. Cause of versioning, small footprint and high performance these frameworks can be interesting for remote communication, too. Besides Google's Protocol Buffers and Facebook's Thrift we also compare some open source frameworks like Etch, Hadoop Avro and Hession.
SOAP Loadbalancing - Speed up your Web Services (17.02.)
Distributing the load among a cluster of servers can accelerate a slow running Web Service. Especially a Web Service that consumes a lot of CPU power and that serves a large number of concurrent clients. The open source SOAP intermediary Membrane SOA Monitor now comes with a loadbalancer for Web Services. The URL rewriting functionality of the monitor, that modifies endpoint addresses and schemaLocations in WSDL documents works together with the loadbalancer. The architecture of the balancer is based on some Spring beans and is therefore very flexible. For example, the dispatching strategy that selects an endpoint in the cluster can be exchanged by other implementations.
Reading WSDL Explained (26.08.)
The Web Service Description Language is used to describe Web Services ubiquitously. Tools reading WSDL documents make it easy to implement or invoke a service. Usually it is not neccessary for programmers to read WSDL in order to create or consume a service. On the other hand WSDL is an essential technology for SOA experts. They write guidelines and rules for WSDL and they have to do quality assureance for WSDL documents and generators. This online article explains how to read a WSDL document using the description of a free Web Service for banking codes. The WSDL is analyzed step by step and transformed into a diagram showing the structure of WSDL.
EIP Patterns using BPEL (24.03.)
In this new series of online articleswe are describing the realization of Enterprise Integration Patterns using the Business Process Execution Language. The first article explains how to implement a XPath Splitter using Glassfish ESB, Netbeans and BPEL.
Glassfish ESB versus Servicemix (24.03.)
This new version of of our online article compares Glassfish ESB v2 GA and Apache ServiceMix 3.3.
Both ESB products are supporting the JBI standard but besides that they are very different.
REST Introduction (18.02.)
Read the translation of an introductory article about the REST architecture. The article uses a lot of examples and diagrams to illustrate the ideas behind RESTful Web Services.
SOAP Monitor (02.02.)
To develop Web Services you have to look at the SOAP messages sometimes. A simple but convenient tool for monitoring SOAP messages is Membrane SOAP monitor. A release of the free tool is available for download now.
