Java APi for Node.js

[pushpinder rattan]

Folks,


Is there any integration of Java and  NodeJs?? Can we invoke nodejs using Java?


thanks
Pushpinder

node-java is an excellent API for calling Java from node: https://github.com/nearinfinity/node-java

The other way around is a bit problematic I think because of the evented nature of node. There is a Java implementation of dnode that may be worth looking at for communication between Java and node processes.

Thanks Rod

ZeroMQ may be an option

[Jeremy Darling]

Rhino is the "Node.js" of the Java world (traditionally speaking).

But, a distributed MQ like Zero is a way to integrate via message passing.  My MongoMQ could also be used as could just about any other MQ that is supported by Java and Node.

If your already using an enterprise system like Tibco EMS you can also place your Node handlers on that bus without too much work.

As for directly integrating the Node runtime into Java, that isn't going to happen (again look to Rhino for that).  Node is native, Java is a VM.  In memory IPC via a C/C++ wrapper is about as close as you could get.

What is your suggestion for a way of hooking up node.js to a Tibco EMS? Would you wrap a native Tibco EMS library as a package for node and do it that way? Just trying to figure this out as node would work very well with Tibco EMS.

Thanks

[Jeremy Darling]

I would look to Rhino for use with Tibco EMS as a BW Process.

That or, the way that we actually did this, create an EMS BW Process that acts as a bridge between a MongoMQ (MongoDB Capped Collection used as a message queue) and TibcoEMS.

If there were a JMS Adapter for Node.js then we could put Node.js processes on EMS.  But alas, I know of none.

strong-mq, via stomp-client, supports ActiveMQ, and ActiveMQ has java/JMS integration. might be one way of cluster java and node code together.

(https://npmjs.org/package/strong-mq, https://github.com/easternbloc/node-stomp-client)

If you're not married to node.js specifically, http://vertx.io/ is a fast, asynchronous polyglot container that supports java and javascript running in the same context. It runs in the JVM and can actually be faster than node for some operations.

There's also some attempts at a node compatibility layer over vertx.io, like nodyn.io.

[Matthew Dalrymple]

Hmmm.. that is unfortunate. I was hoping to have a nice easy way to do pub/sub with Tibco EMS

[Alexey Petrushin]

vert.x, rhino and so on may have good java integration, but it also very exotic way to use JS, it has very little usage in wild - and so you taking high risk by using it.
