Like Spring Boot uses Apache Tomcat, Undertow and Jetty and i have worked on an assignment of same. So just trying to map understanding.
What application server is used by Quarkus?
I have created an application in server and found Jboss libaries, Arjuna Libraries for transaction
which is used by Jboss servers or wildfly servers. But i am not sure whether it is based on Jboss.
Can anyone please clarify?
In short, Quarkus can be thought of as its own application server. However, it is comprised of many open source libraries that have been around for a while, such as:
RESTEasy for JAX-RS
Undertow for the Servlet/Websocket engine
Netty for the network IO layer
Hibernate for JPA
The full set of extensions can be found on the Quarkus Starter website.

I have an application deployed on Tomee which is hosting lots of web services which are written using Jersey framework.
How to identify how many web-services(URLs) are hosted by the application and what is the class having the source code?
I have gone through below article but it gives the list of hosted applications instead of giving list of web-services under one application.
List deployed webapps in Apache Tomcat
If you want an easy way to list these out visually, start up the application locally. Next launch jconsole and connect to the TomEE JVM.
You can then browse the CXF JMX Beans in the tree and you'll be able to find all the deployed endpoints.
I think Kekzpanda's comment is a great method to do this as well: in the startup log TomEE will list all of the deployed endpoints the Path to each.
I'm researching how to deploy RedHat Decision Manger right now, there are two options for running enviroment, JBoss Web Server and JBoss EAP. But I'm new for JBoss and don't know what's the differences between them and which one is more suitable with Decision Manager for production enviroment?
JBoss web server is a server used to deploy web applications, whereas EAP is an application server which can be used also to deploy Java EE compatible applications. EAP gives many more features like messaging, RMI, EJB etc. apart from features provided by Web server.
Which one is better will depend on your use case.
To get more details about the difference between web server and application server refer below post
Difference between a Web server and application server
I know its a very high level question, but it will be very much help full if somebody can help me to kick start the migration.
So please provide some links or use full hints to start with it.
Also if somebody knows about delta changes between JBOSS AS 6 to Wild fly.
Major change which i know that our application uses-
JBOSS AOP
JBOSS Interceptors
and binds it in jboss-aop.xml
like below
<bind pointcut="execution(public * *.DBDAO >updateBO(com.test.model.TestClass, com.test.model.TestClass2))">
<interceptor-ref name="TestInterceptor"/>
</bind>
which is not supported by wild fly now.
And so there must be other thing s which might not be supported by wild fly.
Thanks.
According documentation:
Replace JBoss AOP Interceptors
JBoss AOP (Aspect Oriented Programming) is no longer included in JBoss AS 7. In previous releases, JBoss AOP was used by the EJB container. However, in AS 7, the EJB container uses a new mechanism. If your application uses JBoss AOP, you need modify your application code as follows.
Standard EJB3 configurations that were made in the ejb3-interceptors-aop.xml file are now done in the server configuration file. For a standalone server, this is the standalone/configuration/standalone.xml file. If you are running your server in a managed domain, this is the domain/configuration/domain.xml file.
Applications that integrate AOP interceptors into the EJB layer must be redesigned to use EJB3 interceptors and CDI. Server side interceptors can be changed to EJB3 interceptors, but there is no client side interceptor in AS 7.
Like AOP exist other changes you can see in: How do I migrate my application from AS5 or AS6 to WildFly and Experiences with migrating from JBoss AS 7 to WildFly 8.1
The last link refers to some changes that are not in the official documentation.
Here is whole migration guide from Red Hat. JBoss EAP 6.2 has similar architecture to WildFly so you can use it:

I'm trying to consume a web service within an applet.
For that objective i've tried Apache and Apache2, both with good results
but the problem is that the jar dependencies are far too fat for my application
(the jar for axis or axis2 are over 1.5MB, and the applet is less than 200KB)
So i will try consuming the web service with Apache CXF, hoping that the jars
are at least a bit smaller.
Using eclipse one creates an empty project and in the main classes implements
the applet and blah blah, but to create the web service one must use the web service
wizard.
I've used this wizard before, to consume the web service using Axis, but the moment i choose other options i get this message:
****The Apache CXF 2.x Web service runtime in Tomcat v7.0 Server does not support the client project****
What i´m missing?
I've already installed, CXF 2.x runtime, and the Tomcat 7 Server, and of course the Eclipse Web Tools.
This question How to generate web service client with Apache CXF in Eclipse Helios?
shows a very hard solution and it´s one year old!
is there any other way to consume webservices within an applet?
ksoap2 has no documentation on complex webservices, and ksoap2-android
neither
Sorry for a boring question, but any help is greatly apreciated
Apache CXF 2-x Web service runtime Tomcat Server not support client
The Apache CXF 2.x Web service runtime in Tomcat v7.0 Server does not support the client project
Answer: If you see above error during creating web service client in eclipse using Apache CXF means you are using java project to generate the client from WSDL. Latest version of JAX-WS supports Dynamic Web Module v2.5 and up. So create client using apache CXF first you need to create Dynamic web project.
Once dynamic project created then open web service client wizard to create client from WSDL and issue should be resolved.
Can some body point out how to set up a server and client for cometd application.
i have dojo, and appache server ..
when i browsed through , came across jetty server. Im not sure whether both apache and jetty servers are needed to set the server side.
Thanks
have a look here: http://cometd.org/book/export/html/65
the servlet should work on Tomcat as well as Jetty. It's just that the cometd implementation was done by Jetty people. But it's a standard servlet.
Have a look at the example that i have built it for jboss : Cometd-struts2 example on jboss
