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

I was using STS3 and decided to move to STS4. I got it set up and I imported my projects from the STS3 workspace. These mostly made the transition OK, as I am just learning some basic things, mostly what I have is STS "getting started guides" sorts of projects.
However, I didn't see the default Pivotal tc server in the servers tab, and when I opened the "Define Servers" dialog, "Pivotal tc server" is not available.
Did I miss a step in setting up STS4 or is tc Server no longer the default?
The default Spring Tools 4 distribution doesn't include the Pivotal tc Server Developer Edition anymore (as we did with STS3). This doesn't mean at all that the Pivotal tc Server project is deprecated or anything like that. The reason why we don't include that by default anymore is that the Spring Tools 4 are focused on Spring app development using Spring Boot, which usually happens via running the boot apps via the embedded Tomcat option. As a side effect of this, the distribution got smaller and purely open-source... :-)
But those are the only reasons. We still support running Spring Boot applications in locally installed servers like Tomcat or Pivotal tc Server.
Same question asked differently was answered here
Pivotal server is not included in STS 4
Apparently it is no longer bundled by default, but you can install it. I don't think there was any mention of this change in the Pivotal articles about differences between STS3 and 4.
I'm currently learning how to develop a simple web application with NetBeans. When I'm creating a new web application, the IDE ask me to choose one of the server from the list below. I was just wondering what are pros and cons of each server? Could someone share their expertise in the area?
Your question piqued my interest, so I decided to put in a bit of research.
Amazon Web Services Elastic Beanstalk: is a cloud host more than a simple web server. It's used for deploying infrastructures which orchestrate various AWS services. From the docs (http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/Welcome.html) :
Amazon Web Services (AWS) comprises dozens of services, each of which exposes an area of functionality. While the variety of services offers flexibility for how you want to manage your AWS infrastructure, it can be challenging to figure out which services to use and how to provision them.
With Elastic Beanstalk, you can quickly deploy and manage applications in the AWS Cloud without worrying about the infrastructure that runs those applications. AWS Elastic Beanstalk reduces management complexity without restricting choice or control. You simply upload your application, and Elastic Beanstalk automatically handles the details of capacity provisioning, load balancing, scaling, and application health monitoring.
Tomcat is simply an application server, ie, an implementation of the Java Servlet and JSP specifications only. The question that you should ask is: can I use Tomcat for this project? If the answer is yes, it's probably the best choice.
Pros: ligher memory footprint (typically less than 100 MB).
JBoss and Glassfish are full Java EE application servers, ie, an implementation of the Java EE Application Server specification which fully complies with, and supports, all Java EE features.
JBoss has a larger community than Glassfish. Glassfish however performs better than JBoss and has a very slick GUI-based admin console, whereas JBoss can only be administrated with a command line.
Cons compared to Tomcat: heavier memory footprint (hundreds of MB).
Oracle WebLogic is a full Java EE application server. It is a proprietary product however.
Pros compared to JBoss and Glassfish: very stable and robust.
Cons: licensing cost.
Wildfly is just the next iteration of JBoss, after JBoss AS 7.x - basically, it's JBoss AS 8.X with a different name.
Edit: here are a few other servers which can be of interest.
IBM WebSphere: IBM's application server.
Pros: integration with IBM's other products (IDEs, services, engines...)
Cons: licensing costs.
Jetty: is a set of software components that offer HTTP and servlet services.
Pros compared to Tomcat: lighter memory footprint (circa 50MB), very flexible, very easy to set up.
I want to ask about JBoss Middleware for ISO8583.
So, I kinda new on ISO8583, from what I know is we could use JPOS framework for this one. Then my supervisor ask me to research about JBoss Middleware that could be used to develop middleware application for send, receive, and parse ISO8583 message.
I have read on JBoss Middleware website, unfortunately I'm still not sure which JBoss technology should I use to develop such application.
Here is my questions:
1. In order develop enterprise application that capable to send, receive, and parse ISO8583, should I combine JPOS with JBoss Middleware? or JBoss Middleware has a complete capability to handle it?
2. Does anyone has/know good material/tutorial for me to learn about building ISO8583 middleware with JBoss technology?
Thank you.
JBoss Middleware is a family of products and its components alone do not provide ISO8583 capabilities out of the box.
jPOS is one of the most popular Java frameworks that provide complete capabilities to handle sending and receiving ISO8583 messages. There are other alternatives such as j8583 and IsoTypes.
You can combine any of these ISO8583 libraries together with JBoss Fuse (part of the JBoss Middleware family) to build a solution capable of sending, receiving and parsing ISO8583 messages.
I'm not aware of a definitive guide about building such solutions. If you need to use JBoss Middleware, you can follow this route:
Look into IsoTypes, which provides an ISO8583 marshalling library for Apache Camel (used by JBoss Fuse).
Start by building a Camel route that implements the IsoType library functions. Look into this sample project.
Please, be aware that building a production ready ISO8583 server and/or client from open source solutions require significant work in terms of scalability, information security and compatibility with multiple financial hosts and switches.
My answer only refers to the first basic steps to understand your problem/solution fit a bit better.
As a side note, you may be interested in looking at jreactive-8583, an ISO8583 connector that handles message parsing and the network layer out of the box. You may build your application using this and deploy it into JBoss Application Server (part of the JBoss Middleware family too). I use it in production.
You can take advantage of JPos Q2 and create a servlet deployable to JBoss container.
In the service init method you can do this:
Q2 q2 = new Q2();
q2.start();
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.
For a variety of unfortunate management reasons (budget constraints etc.) I, the developer, have been put in the position to deploy the app in a production environment. The catch is that I don't have any experience in production EJB application server deployment. That said, they are aware that there are no guarantees of success.
The context:
The dev server runs on the latest version of Netbeans with Glassfish v3, on a mac machine
98% / 99% uptime is ok, there are no financial/critical transactions
It is a client/server EJB 3 app, and the web tier, business tier, and resource tiers currently run on the same machine.
I have the liberty to choose the hw/sw infrastructure
Load estimations: 10 simultaneous connexions avg, rare 200 peaks
The outbound public data is text/small pics (it's for iPhone clients), inbound HTTP text only
Basic maintenance will be taken care of (backup, server reboot, etc)
My questions for production deployment:
What are the must haves infrastructure-wise? Minimum system specs etc?
Is it ok to keep Glassfish v3?
Which configuration aspects of the server should I focus on?
Worst case scenario: if I deploy the same software infrastructure (Netbeans/Glassfish v3) as during the development, would the server keep up?
Any piece of advice would be most welcome. Thanks!
For the architecture, you can start small with just a single GlassFish instance with no front web server (GlassFish has one built in that is very capable). If you can wait for the release of GlassFish 3.1 you'll be able to add instances (clustered or standalone) and offer scalability and centralized admin.
Most production instances of GlassFish I've seen run with 1GB-2GB of JVM heap (-Xmx) but your mileage may vary if you load lots of data in memory or if you use some frameworks. If you want better reliability, having them on separate machines is a plus obviously. With two instances on the same machine you can offer continuity of service if one instance fails (but not if the machine fails).
I'd suggest scripting as much as possible the provisioning of the resources (connection pool , JDBC datasource, etc...) and applications using the "asadmin" command-line tool and try to not use NetBeans on the production platform.
Benchmarking with simulated load sounds like a wise thing to try to put together before going live and this survival guide will probably come in handy.
You don't mention the database. Isn't there one?
I suggest the following:
Not a Mac expert but I'll say go with 6GB or more RAM
HDD space is not a problem these days
Do not know much abt Mac Processors (watever eq of dual core etc)
Personally I have not used GF3 in Production but I hope it's stable now so you should be ok.
System Architecture:
Receive all HTTP requests on some web server (Apache or Sun web server) and load balance with your Glassfish server(s).
Now depending on your physical (or virtual) machines create instance of Glassfish Application Server on each machine. If you just have one machine then create atleast 2 instances of Glassfish. This will help to put one node down for maintaince and other to keep going.
As far as deployment is concern make sure you stop debug logs and fine tune JPA logs etc.
Use Ant or other scripts to deploy code and taking backup of existing code.
I hope this will help to kick start and rest you can ask or solve as you go along.
Good luck.
