WSO2 Tungsten Release Notes

May 23rd, 2006

WSO2 Tungsten 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-Reliable Messaging, WS-Addressing, WS-Policy and more, giving a full secure and reliable infrastructure that interoperates with both J2EE and .NET frameworks using open standard protocols.

WSO2 Tungsten is built on Apache Axis2, the popular Web services foundation developed by WSO2 engineers (and others) at the Apache Software Foundation. It integrates other core Apache Web services projects including Apache Axiom and Apache Sandesha2 to form a production quality, comprehensive Web services server platform.

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

WSO2 Tungsten can be used as a standalone server or within a J2EE compliant servlet container. It also contains client components required to communicate with services. The support for Reliable Messaging and WS-Security means that WSO2 Tungsten is ideal for hosting B2B solutions, or building enterprise class integrated applications.

Known Issues

1. The AJAX dynamic client feature is still at an experimental stage. It has been successfully tested for simple types, simple type arrays and complex types but we still do not support complex type arrays.
2. POJO to Web service feature is still at an experimental stage. One can upload 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 its transformed into 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 services will not work.
3. Once in a while user might encounter the message "Your session has expired please login".When this happen Tungsten console automatically logs out. User can safely ignore the above message and carry on his work.
4. WS-Policy support is still in the experimental stage and limited to single port scenarios.
5. You cannot have two different versions of the Apache Sandesha2 module in the system.
