WSO2 Web Services Application Server(WSO2 WSAS) 3.0.1
Release Notes
27th February 2009
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. WSAS is based
on the revolutionary WSO2 Carbon [2] framework, Middleware a la carte'.
Now you can adopt the middleware to suite your enterprise architecture.
All the major features have been developed as pluggable Carbon components.
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, Apache Savan
, and Apache Neethi to form a production quality, comprehensive Web
services server platform.
An open source product, WSO2 WSAS is available under the

Known Issues
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 it's transformed
into
an AAR, its services.xml will be replaced by the generated services.xml.
In
addition to this, the user cannot 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.
WS-Policy support is limited to policy expressions with a single policy
alternative.
You cannot have two different versions of the Apache Sandesha2 module
in the system.
Persistent RM is still in the experimental stage
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.
The 'Try It' feature does not work for MTOM enabled services.
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
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6209663.
To rectify this, you should edit the /etc/hosts file on the server
machine and set
the correct IP
address.
Data Services, Axis1 services, Javascript services & POJO services
cannot be
deployed using the URL-based repository configuration
