| Apache Synapse Enterprise Service Bus (ESB) - 2.0.0 Release Notes - January 2011 |
| |
| 1. Overview |
| The Apache Synapse ESB is a robust, lightweight and highly scalable and distributed |
| open source Enterprise Service Bus (ESB). It supports SOAP Web services as well as Legacy |
| services over transports such as JMS, Apache VFS File systems, Mail etc, and SOAP, REST/POX, |
| plain text and binary message payloads. (Please see http://synapse.apache.org for more details) |
| |
| Apache Synapse graduated from the Apache Incubator on the 2nd of January 2007, and the first |
| Synapse 1.0 was released on the 11th of June 2007. On the 20th of December 2007, Synapse was |
| accepted as a top level project (TLP) under the Apache Software Foundation. |
| |
| 2. Installation Prerequisites |
| |
| Apache Synapse requires a J2SE runtime of version 1.5.x or later. Running the samples also |
| requires Apache Ant 1.7.x or later. Although Synapse would run with a JDK > 1.5.x, the Script |
| mediator may not properly function on these JDKs. Building Synapse from source requires |
| JDK 1.5.x or later, and Apache Maven 2.1.0 or later |
| |
| 3. Quick start |
| Please see the docs/Synapse_Quickstart.html guide |
| |
| 4. Building the Samples |
| Please see the documents docs/Synapse_Samples.html and docs/Synapse_Samples_Setup.html |
| |
| 5. Synapse configuration language |
| Please see the document docs/Synapse_Configuration_Language.html |
| |
| 6. Extending Synapse |
| Please see the document docs/Synapse_Extending.html |
| |
| 7. Known Issues and limitations |
| |
| * SYNAPSE-180 Does not support throttling by concurrency within a cluster |
| * SYNAPSE-186 Does not support HTTP some of the REST operations (such as put/delete etc) |
| * SYNAPSE-181 Does not yet support JTA transactions |
| * SYNAPSE-330 Does not yet support load balancing with session affinity using SOAP sessions |
| * SYNAPSE-280 Does not preserve CDATA sections within payloads |
| * SYNAPSE-307 The XSLT mediator will not report errors encountered in a provided stylesheet |
| |
| * The Synapse JMS implementation supports JMS 1.0.2b, however due to licensing issues we include |
| the JMS 1.1 spec JAR from Apache Geronimo (geronimo-jms_1.1_spec-1.1.jar) instead. If you have |
| any issues with JMS 1.0.x, please download the Sun JMS 1.0.2b JAR and replace supplied JAR from |
| Geronimo. |
| |
| 8. Frequently asked questions |
| |
| * How can I change the default logging level of Synapse? |
| Edit the lib/log4j.properties and set the line "log4j.category.org.apache.synapse=INFO" to |
| "log4j.category.org.apache.synapse=DEBUG" and restart Synapse. |
| |
| * If you get an error related to WS-Security or when using it, check to ensure that your JDK |
| uses the "Unlimited Strength Jurisdiction Policy Files". These could be downloaded from |
| http://java.sun.com/javase/downloads/index_jdk5.jsp Refer to the associated documentation |
| for instructions on how to install it to your JDK. |
| |
| * If you encounter issues with your JDK related to XML processing, try placing the Xerces jar |
| files xercesImpl-2.8.0.jar and xml-apis-1.3.03.jar in your <JDK>/jre/lib/endorsed/ directory. |
| |
