Known Issues

1. 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.
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 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.
8. Data Services, Axis1 services, Javascript services & POJO services cannot be deployed using the URL-based repository configuration
