Apache Synapse 1.1.1 released

The Apache Synapse team is pleased to announce the
release of version 1.1.1 of the Open Source Enterprise
Service Bus (ESB). Apache Synapse is an lightweight and
easy-to-use Open Source Enterprise Service Bus (ESB)
available under the Apache Software License v2.0. Apache
Synapse allows administrators to simply and easily
configure message routing, intermediation,
transformation and logging. The runtime has been
designed to be completely asynchronous, non-blocking and
streaming. This is the first release since Apache
Synapse became a Top Level Project (TLP) of the Apache
Software Foundation.

The Apache Synapse project and the 1.1.1 release can be
found here:


Apache Synapse offers connectivity and integration with
a range of legacy systems, XML-based services and SOAP
Web Services. It supports non-blocking HTTP and HTTPS
using the Apache HTTPCore (http://hc.apache.org)
components, as well as supporting JMS (v1.0 and higher)
and a range of file systems and FTP sources including
SFTP, FTP, File, ZIP/JAR/TAR/GZ via the Apache VFS
Synapse supports transformation and routing between
protocols without any coding via configurable virtual

The 1.1.1 release contains a set of enhancements based
on feedback from the user community, including:

* Clustered deployment support

- Clustered support for the Cache and Throttle

- The ability to pin services or tasks to specific
server instances

* Maintenance mode for the HTTP and HTTPS transports:

- this allows the administrator to pause the transport,
so that new work is not accepted but existing requests
are correctly processed.

* JMX monitoring support

* New Callout mediator enables simple message flows to
implement the callout integration pattern

* Performance and stability improvements to the JMS and
VFS transports

* Better support for pure XML and REST patterns

* Support for creating POJO-based mediators using

The combination of XML streaming and asynchronous
support for HTTP and HTTPS using Java NIO ensures that
Synapse has very high scalability under load.
Performance tests show that Synapse can scale to support
thousands of concurrent connections on standard server

Apache Synapse ships with over 50 samples
designed to demonstrate common integration patterns
"out-of-the-box", along with supporting sample services,
and service clients that demonstrate these scenarios.
Apache Synapse is configured using a straightforward XML
configuration syntax

Apache Synapse is openly developed by a community that
welcomes all forms of input, ranging from suggestions
and bug reports to patches and code contributions. Your
comments and feedback on the project and release are
welcomed. The Apache Synapse code and binaries are
available from the website at
