Migration of JBoss server from 4.0.5 GA to Wildfly - jboss

My organization's development environment is quite old and still uses JBoss 4.0.5 GA as a Development Application server. We would like to switch to modern servers such as wildlfly. What are the steps to be taken for the same? are there any resources available online for this? which version of Wildfly should we migrate to considering our application uses primarily JAVA EE8 API?

How can I monitor wildfly version 20 on zabbix 4.0?

I have done everything possible from my end.
OS Linux data is coming from server.
but data of wildfly (i.e heap thread etc.) is not coming.
does anyone have template of wildfly 20?
There are several solutions widely available on the internet
Zabbix-JBoss-Agent
Zabbix_wildfly_eap_jboss_monitoring
WildFly (formerly JBoss) is a Java application and can be monitored with JMX agent
I would strongly recommend upgrading to a newer version of Zabbix, as version 4.0 will become unsupported on October 31, 2021.

Where can I download Rational Application Developer (RAD) 7 and WebSphere Application Server (WAS) 7?

I have been searching for RAD 7 and WAS 7 from IBM but could not find the relevant installers. I have an application that requires this version and I still have not been able to open it. I clarify that I need the specific version and not a different one (Neither previous nor superior).
I am grateful if you can tell me where I can download the versions of the indicated applications, no matter if they are the test versions or they are housed in unofficial repositories.

Why OptaPlanner example runs very slow on WildFly but fast on Oracle JVM?

I modify the OptaPlanner 6.5 course timetabling example to a REST service using the vehiclerouting web example as a template. We found that the web version of course timetabling run very slow as compared to pure Java version of course timetabling.
For example, the pure Java edition timetabling system can get a 0Hard/-352Soft score. But the web edition can only get -7Hard/-1108Soft. No matter how long we run the example.
The web edition is hosted in a WildFly 9. The JVM versions we use are both Oracle JVM 1.8; Further, we tried using WildFly 10. And the result is the same.
Can anyone shed some light on it? I want get the same performance in web edition as Java edition.

jboss enterprise soa platform versions

There are 2 major(4.x.x and 5.x.x) versions of JBoss Enterprise SOA Platform. I got these information from an article on redhat site (https://access.redhat.com/site/articles/111773).
I do not see versions prior to 4.2.0 on the download page for SOA platfrom.
SOA platfrom Download page :
access.redhat.com/jbossnetwork/restricted/listSoftware.html?product=soaplatform&downloadType=distributions
In addtion to this, I have searched the press release page on redhat.com and it shows 4.2.0 as the first version.
http://www.redhat.com/about/news/press-archive/2008/2/jboss-soa
I would like to know why the JBoss Enterprise SOA Platform version is started from 4.2.0?
If there are any prior versions before 4.2.0, why they are not downloadable from redhat.com download page?

Can I use JBoss EAP 6 without a support license?

JBoss Application Platform has 2 distributions, a community and an enterprise release, community releases are like Beta releases of enterprise releases, JBoss 7.0 is then actually EAP 6 beta 1, 7.0.1 is beta 2, 7.1.0 is beta 3 and 7.1.1 is rc 1.
What happens with JBoss AS 7.1.2 and 7.1.3? this is a very informative link: http://henk53.wordpress.com/2013/01/09/the-curious-case-of-jboss-as-7-1-2-and-7-1-3/
So my question is: Can I use JBoss EAP 6 without a support license?
Downloads are available from access.redhat.com/downloads, from which you have to click on "Evaluations and Demos", and then on "JBoss Enterprise Application Platform Evaluation".
I have read that JBoss EAP is still open source and you can use it freely, but only if you compile it from source, which is not an easy task nor they want it to be.
So if I use in production the version I have downloaded from "Evaluations and Demos", is this illegal?
TLDR; yes, you can use without a support subscription, but no, if you just download the latest EAP binary, you're not allowed to use it in production.
Three cases here to consider how you can run JBoss EAP without a support subscription, two of which also allow production use:
1. Development use
You can use any JBoss EAP binary version for development purposes without a paid subscription. You won't get patches or support that way, and you can't run it in production. From "Downloads for Development Use":
To download JBoss EAP you must have an account. You also need to
accept the terms and conditions of the JBoss Developer Program which
provides $0 subscriptions for development use only.
2. EAP 6.x alpha versions
All alpha versions, such as JBoss EAP 6.1 Alpha, are free to use in any way or form, also in production. From this message:
The 6.1 Alpha binary is made available for free (both for development
and production use) to the entire community.
And this thread:
This development restriction, however, does not apply to EAP alpha
releases. EAP alpha releases may be ran in production if you so
desire. As to their quality, 6.1.0.Alpha is of equivalent quality to a
community final release. However, the Alpha is where the extensive
testing and hardening begins, so we recommend GA or later for
production if you are interested in using EAP.
This is also confirmed by entry in JBoss FAQ, saying
Q: If EAP 6.1.0.Alpha is the same as community 7.2.0.Final, why is it
called Alpha? A: EAP has a much more conservative and rigid release
hardening process, including extensive quality testing and partner
certification. Historically every EAP release starts from our most
recent community final, and then releases in stages as this hardening
work is performed. The first EAP stage Alpha is of equivalent, or
better, quality to a community Final release.
Q. Are there any restrictions on how I can use EAP 6.1.0 Alpha? A. No
– it has the same license and terms as AS releases however as it's an
Alpha release we don't recommend using it in production.
And these two redhat knowledgebase articles confirming that EAP 6.3.Alpha is also available for all to run in production (only visible for paid subscribers):
"Red Hat JBoss EAP 6.3 Alpha Availability"
"Using JBoss EAP alpha version in production without support subscription"
Edit: and now John Doyle, Senior Manager responsible for Red Hat JBoss EAP 6, confirmed that
The earlier statements about EAP 6.1 Alpha apply to all EAP 6 Alpha
releases. They can be run in production.
3. Self-compiled versions
EAPs are also available as source distributions, and if you compile them yourself, removing any Red Hat trademarks, it should be legal to run them in production. Of course, you are completely on your own on supporting them. To make compiling easier, there is a script on this github account, and using that script building your own EAP is as easy as
git clone git://github.com/hasalex/eap-build.git
cd eap-build
./build-eap.sh
See the project readme for details. There's also extended discussion on one of its issues about the legal status of the build, which refers to statement by Jason Greene, WildFly project lead, saying one of the ways to legally use the product is
Self build and support EAP - You get some of the benefits of the enterprise releases (e.g. patches to older major versions and so on),
but you have to invest time and energy to build and maintain/verify
your app server distribution bits.
I think the answer is: sort of. You can obtain the binary version of the latest JBoss EAP 6.1.0.Alpha if you agree to a $0 developer license and agree to use it only for development purposes. You do not get patches or support, however.
Also, it's open sourced under the LGPL in which case you don't have to agree to anything beyond the LGPL. But then the trick is getting the source. And you won't be getting the patched source. An important consideration here is that the binary package is configured carefully (e.g. with respect to security defaults) whereas you're on your own if you compile it from available source.
Bottom line: buy a license if you are using it for any important commercial purpose so as not to be at some arbitrary fixed point in the source's evolution.
Red Hatter here. If you use JBOSS binaries, they are Red Hat Intellectual Property. You have to have a Red Hat subscription to use the software which may be $0 cost (developer use only) or more depending on what are your needs and/or subscription compliance (non-developer use like non-production or production).
Please see http://www.jboss.org/terms-and-conditions/ for the details.
Answer to original question "Can I use JBoss EAP 6 without a support license?":
According to official "Subscription Guide for Red Hat JBoss Middleware" dated Sept. 2015 (https://www.redhat.com/en/resources/subscription-guide-red-hat-jboss-middleware) you are allowed to use JBoss EAP 6 without support license only in following cases:
a) Environments only used by one person like a developer, testcase developer, architect
b) Developer desktops/ laptops or
c) Single-user development instances on a server (physical or virtual)
So you have to pay subscription for Test/QA and Production environments.
