14. EJB Mediator
• Can call an external Enterprise JavaBean
hosted in a app server
• Stores the result in the message payload or in
a message context property.
• Currently supports EJB3 Stateless Session
Beans and stateful session beans.
16. Better XSLT and XPATH
• Supports XSLT 2.0
• Improved XSLT performance
– Almost doubled in most cases
• Support XPath 2.0
– Not enabled by default
17. JSON Improvements
• JSON streaming support
• Supports multi-rooted JSON
• JavaScript mediator support for JSON
{“name”:”miyuru”}
<script language="js">
var symbol = mc.getPayloadJSON().name.toString();
……..
</script>
<script language="js">
mc.setPayloadJSON({“name”:”miyuru”});
……..
</script>
18. MSMQ Transport
(Microsoft Message Queuing)
•http://docs.wso2.org/wiki/display/ESB450/MSMQ+Transport
•http://docs.wso2.org/wiki/display/ESB450/Sample+270%3A+Transport+switching+fr
om+HTTP+to+MSMQ+and++MSMQ+to+HTTP
• Sends/receives messages to/from MSMQ
queue
• Connects to MSMQ using native interface
– Only works in Windows
<endpoint>
<address uri="msmq:DIRECT=OS:localhostprivate$msmqTest"/>
</endpoint>
<proxy name="msmqTest" transports="msmq" startOnLoad="true">
……
19. SNMP monitoring
• Alternative to JMX
• Exposes all JMX MBeans via SNMP
• Can be easily integrate with monitoring
systems in data centers
– Transport statistics
– Service statistics
– Endpoint statistics/status
20. Mediation libraries
• New extension point of WSO2 ESB
• Mediation Library is a mechanism to group
Templates, Class mediatiors and Jar libraries
and expose it as a self contained set of
function modules.
• Once deployed, mediation library can be
import and use in mediation flow
Mediation Library
Sequence Class
SDK
Templates Mediatos
21. Mediation Libraries..
• Working on creating libraries for many cloud
APIs
• Library can import to runtime using
<import …/> configuration element
• After that call-template mediator can be used
to invoke mediation library functions
22. Multi-tenant support
• Standalone products supports multi-tenant
• Seamless migration from on-premise to cloud
• No need for a fully fledged cloud setup to get
the benefits of MT
24. Management & Worker Node Separation
• Proper separation of concerns - management nodes
specialize in management of the setup while worker
nodes specialize in serving requests to deployment
artifacts
• Only management nodes are authorized to add new
artifacts into the system or make configuration
changes
• Worker nodes can only deploy artifacts & read
configuration
• Lower memory foot in the worker nodes because the
management console related OSGi bundles are not
loaded
25. Management & Worker Node Separation …
• Worker Nodes can be added to cluster on-the-fly
and WSO2 ELB will automatically discover and
route traffic to new nodes.
– Using cluster messages to discover nodes
– Automatically detects node failures
• Improved security - management nodes can be
behind the internal firewall & be exposed to
clients running within the organization only, while
worker nodes can be exposed to external clients.
27. Improved Deployment Synchronization
• DepSync allows you to synchronize
deployment artifacts across nodes in a cluster
– Management node(s) commits artifacts to repo
– Worker nodes checkout artifacts from repo
– Using SVN as the repository
• Also includes meta data synchronization
• New nodes can add to cluster on-the-fly and
artifacts will pull from repository
