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.
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
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
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
