Is It possible to add an agent to punjab xmpp server?
I've seen that there is a experimental support for twisted apps. newrelic info
Although there is experimental support for Twisted it is just that... experimental. New Relic does not have available instrumentation for XMPP entry points at this time. In short, there is not much that could be done with a Punjab/XMPP application using New Relic for now.

For one of my application, I have implemented Web socket using socket.io and hosted in IIS. Currently socket connection helping to provide two way connection between client (React) and server (node.js).
As I mentioned, I have hosted my application in IIS. I have few doubts regarding Turn Windows features on or off -> Internet Information services -> World wide Web Services -> Application Development Features -> WebSocket Protocol. I have tested my application without enabling this feature, its working fine, but I would like to confirm below stuffs.
WebSocket Protocol
Do I really need to enable WebSocket protocol feature to make websocket work in my application? If so, how now it is working fine without enabling (I haven't do performance and stress testing, I may face issue on this).
What if I not enabling this feature? in short what is the actual use of this feature?
It would be helpful if anyone answer the above questions. Thanks in advance.
WebSocket as part of the HTTP stack requires a bunch of things to be ready on Windows (across multiple components), so hope this answer helps a little.
HTTP.sys, a driver deep down in Windows OS, is upgraded to support the necessary packet communication required by the protocol.
The IIS WebSocket module, an IIS extension which many other Microsoft frameworks (like SignalR) depend on.
So WebSocket support is by default on in HTTP.sys, and you don't need the IIS module if your framework (socket.io) has no dependency there.
Note that the "Summary" section provides several useful links,
https://learn.microsoft.com/en-us/iis/get-started/whats-new-in-iis-8/iis-80-websocket-protocol-support#summary
and the same article also reveals that IIS WebSocket module has
conflicts with socket.io.
Hi I am developing an XMPP chat application. The chat is working properly and I have a problem with Stream Management. I have added the following settings in my server
In this I enabled stream_management. But I am not able to get sm xmlns='urn:xmpp:sm:3’ while connecting. Is there any other setting required for this? Please help me to solve this issues.
I expect that you are using an old ejabberd version (like for example ejabberd 2.1.11. ejabberd 2.1.11 does not support stream management, so what you see is the expected behaviour.
If you want to use stream management, you need at least ejabberd 14.07, but preferably the most recent version is better.
We could see JBI in Glassfish V2 but it is not in V3, what's happening? Which application server is useful for SOA development?
can I deploy WSO2 on Glassfish or JBoss?
RGDS
I'm not sure this answer is definitive, just based on my own experience with these systems.
JBI isn't a Glassfish feature (if it ever was its news to me). Its a (kinda/sorta) Sun community standard which has many implementations (ServiceMix to name one of several) that can be installed on any J2EE container (such as Glassfish to name one). Although it was once very popular it seems to have fallen on hard times of late, perhaps simply because ESB hype got swamped by the new wave of cloud hype.
WSO2 is much larger and includes JBI as one of its many options. By default its based on its own embedded Tomcat, but WSO2 claims its possible to run it on an external Tomcat (I never managed to make this work). To my knowledge no one has tried or succeeded to make it work on Glassfish.
Are there any websocket plugins for nodejs; I would like to develop some application that uses websockets.
Checkout Socket.IO - it's a widely used and powerful Node module for socket connections.
WebSocket-Node is a pure WebSocket implementation in node.js that supports the latest version of the WebSocket spec (version 8), and is still being actively maintained.
Otherwise Socket.io has broader browser support because it can fall back to things such as Flash Sockets, long lived iframes etc.
Like cmpolis mentioned, Socket.IO is excellent. Just upgraded to 0.8 too.
nowjs also provides a higher-level api if you like more abstraction.
Similar to nowjs, dnode allows you to call remote functions between the client and server and vice versa.
Here is a great SO answer delineating the differences between them.
I am looking for a kind of java ee application server. My company is using Websphere application server and I am reviewing jboss. I am not familiar with WAS, would anybody like to tell me which outstanding features provided by IBM WAS? And what the common features between WAS and JBOSS.
I write down my understanding firstly.
IBM WAS Outstanding(Specified) features:
1. LTAP
2. Monitor Tool
3. IDE(RAD) --- not sure is it free?
4. Integration with IBM portal(since we are using this product as well)
5. Integration with IBM MQ(above reason)
6. Webservice extension support(WS_*)
7. .....cool websphere library??? no idea, who would give me a sample?
Common features in WAS and JBOSS
1. Vendor service support
2. Java EE and EJB 3.0
3. Clustering
4. Any reasonable features for web2.0 application?
I don' think you should make comparison this way. Get the IBM team to provide you their list and speak to RedHat and get their list and then make the comparison.
RAD is not free by any means.
WAS is a good stack as it has a good track record in high volume sites and is the foundation of a number of IBM products (e.g Process Server, Portal Server etc).
The flipside of WAS is the learning curve is steep and the machine requirements are steep too.
Historically WAS was lagging in the support for latest versions of Java EE. Things are improving these days though
