10th June 2008

WSO2 WSAS is the Enterprise ready Web services engine powered by Apache Axis2. It is a lightweight application server for Web services that incorporates leading open source components into a simple, easy-to-use and highly performant package.

It supports Java components as services using both SOAP and REST models. Web services support include WS-Security, WS-Trust, WS-SecureConversation, WS-Reliable Messaging, WS-Addressing, WS-Policy, WS-SecurityPolicy and more, giving a fully secure and reliable infrastructure that interoperates with both J2EE and .NET frameworks using open standard protocols.

WSO2 WSAS is built on Apache Axis2, the popular Web services framework mainly developed by WSO2 engineers. WSO2 WSAS provides many value additions on top of Axis2, making it a more enterprise ready product. It also integrates other core Apache Web services projects such as Apache Axiom, Apache Rampart, Apache Sandesha2 , and Apache Neethi to form a production quality, comprehensive Web services server platform.

An open source product, WSO2 WSAS is available under the Apache Software License (v2.0) . This includes all of the extra integration and management functionalities as well.

Known Issues

  1. POJO to Web service feature is still at an experimental stage. One can upload a jar/zip file and can create an AAR out of it. If you uploaded a jar/zip file which has the semantics of an AAR, when it's transformed into an AAR its services.xml will be replaced by the generated services.xml. In addition to this, the user cannot give associate any library dependencies or web content with the generated AAR file.
    • Due to limitations in Axis2, method overloading is not supported, and hence the WSDL for services where methods are overloaded cannot be generated. Hence all WSDL based functionality related to such services will not work.
  2. WS-Policy support is limited to policy expressions with a single policy alternative.
  3. You cannot have two different versions of the Apache Sandesha2 module in the system.
  4. Persistent RM is still in the experimental stage
  5. A <parameter name="OmitSOAP12Action">true</parameter> entry has been added to the HTTP & HTTPS transportSenders in order to overcome some issues with some browsers. In case of interoperability failures, please change the value of this parameter to false and retry.
  6. The 'Try It' feature does not work for MTOM enabled services.
  7. Cannot connect to a JMX service using a JMX client tool such as jconsole from a remote machine when the server is running on Linux. See To rectify this, you should edit the /etc/hosts file on the server machine and set the correct IP address.
  8. Data Services, Axis1 services, Javascript services & POJO services cannot be deployed using the URL-based repository configuration
