I am looking for an SNMP adapter for JBoss 7.
So far I have found that there was one developed for JBoss 5, and I also found a discussion here where someone has taken the old code and started making compatible with 7 but work is far from finished.
Anyone has any more information I am lacking on this subject?
Well after sometime, I will answer this question.
There is no more information on the subject. Work remains to be done. :)

The GWT RPC mechanism is great for client initiated communication. We're looking for a solid, supported way to do Push notifications from the server to the clients. All the solutions we can find are several years old and don't seem to work with newer versions of Eclipse and GWT.
We're prepared to use the Google App Engine if that helps.
We can roll our own socket code if that helps, as well, but we are Java developers. Writing JavaScript to do socket work would be a last resort, although if that's what it takes and there are examples we could probably handle it.
Any pointers to sample code or suggestions as to packages to use are greatly appreciated.
You could use the Atmosphere Framework. They have a gwt20 module which works great with gwt.
As far as I know there are two possible solutions.
First you can use Errai. Errai has an event bus which also can be used on the server:
https://docs.jboss.org/author/display/ERRAI/Messaging+API+Basics?_sscc=t
I did not use it, but think it is possible to do server push.
The second framework I know is gwt-comet:
https://github.com/rzschech/gwt-comet
I did not use one of them. But if I would look for a server push solution, I would give gwt-comet a try.
I wondered if any of you know, if there is support for NeuronDotNet 3.0. The website neurondotnet.freehostia.com is down, and I am looking for more example Files or instructions how to properly use the library.
Do you guys have any ideas? I would be greatly appreciate them.
I recall there being a message on the site stating that the project had been discontinued. If you are looking for a .Net neural network API you might condier.

I followed the path of Java EE for quite a while now, used JBoss Seam and followed its standardization within CDI.
Now after trying to solve the first steps on the hard path from Seam 2 to 3 migration, I learned that all was moved to Apache Deltaspike.
But while Seam was decently documented and equipped with examples, Deltaspike is not. There are menu items leading to "Documentation", which is very poor, littered with TODOs and without any visible structure and to "Examples", which is more or less a joke.
Ever since I tried to step up to Java EE 6, I feel a bit like standing in the rain - even though it's great, that many concepts of Seam 2 went into the standard, I miss many things I had before - and exactly those things should be covered by CDI extensions. Here again, it's great that there is a common effort to channel those extensions in a project like Apache Deltaspike - but at the moment there is a very high hurdle to get benefits from it, even if you're not a beginner in the technology.
So - can anyone lead me to decent resources, documentation and examples how to use and understand the CDI extensions?
As noted in other responses, the DeltaSpike documentation is a little lacking. You could always take a look at the tests and javadoc. For examples, I think you'll find JBoss jdf quickstarts to be the best location for examples currently. Do a search on the right for DeltaSpike and you should see around seven examples.
DeltaSpike is still early in its development. It is only at version 0.3; it might be quite some time before it's production-ready. Until then, you might take a look at MyFaces CODI or Seam, two projects whose development has halted as they are presently being merged into DeltaSpike.
The documentation at the DeltaSpike web site, I agree, is quite insufficient for users; I bet it's just for people that want to test it out or develop for it.
Here's a concrete example. I am a reasonably experienced software person. I would like to use DeltaSpike BeanProvider.getContextReference to inject an EJB into some code that is not itself an EJB. I included the requisite Maven dependencies and added the BeanProvider.getContextReference code to one of my classes. I'm getting error messages that tell me that DeltaSpike is not configured. Two hours with the documentation did not get me any closer to understanding what I need to do simply to turn it on. What seems to be missing is a "How to configure DeltaSpike core." page.
Can someone please help with advantages of JBoss over WAS?
Any help or reference is appreciated.
Thanks.
Here is one from IBM website. Most of the comparisons I believe will be biased.
Here is another discussion thread.
NOTE: The comparison should be done based on your use-cases and SLA requirements. Otherwise it is just theoretical.
I am new to Blackberry app development. I need to call REST webservice from blackberry application using JDE 4.7. I searched but not got any solution. Anyone help pls?

You have to make an HttpConnection request and read the data as an InputStream... have a look at this tutorial Calling REST based web services
I appreciate this an old post - but it has been updated so someone is looking at it, so I thought it appropriate to contribute.
I am sorry, but I can not recommend the code supplied the link from another answer called "Calling REST based web services".
I have made a comment explaining this on the site, along the following lines:
"In my opinion this code is flawed because it does not consider the different connection methods, nor does it consider different encodings. More over it does not consider the Event Thread or provide reasonable error checking and logging. I appreciate that this is just a sample, but I think the author has a responsibility to make people who might use this code aware of how it should be used properly. And this code will cause more problems that it solves. Refer to the supported BlackBerry documentation and web sites for better samples."
Sorry, I am not as familiar as I should be of the questions asked on stackoverflow, but questions like this come up regularly on the BBRY forum here:
http://supportforums.blackberry.com/t5/Java-Development/bd-p/java_dev
I recommend that you go on that forum and type network in the Search box on that site and you be presented with a range of tutorials and KB articles that discuss all aspects of networking. In this particular case I would recommend this:
http://supportforums.blackberry.com/t5/Java-Development/What-Is-Network-API-alternative-for-legacy-OS/ta-p/614822
Networking is not trivial on the BlackBerry, do not expect a cut and paste of the code supplied to work for you. Specifically you should be aware of:
a) The various connection methods, the costs associated with each and the impact that using each might have (e.g. transcoders or caching)
b) The Event Thread, how to get off it and back on when processing a response
c) Logging and reporting so that you can investigate problems when they occur (and they will).
Personally, given that all OS 4.7 devices can be upgraded to OS 5.0 and should be, since OS 5.0 is better, I would forget supporting OS 4.7. Instead look at OS 5.0 and above support and use ConnectionFactory.
