I am looking at the latest websphere liberty 8.5.5.7 full platform (https://developer.ibm.com/wasdev/downloads/liberty-profile-using-non-eclipse-environments/) and I wonder if it can run oracle java 8? I see on the download page that ibms java 8 only supports the web profile but I don't care if i run a jdk from oracle or ibm as long as it is version 8.
Historically websphere has demanded ibms jdk on linux and solaris.
I have search ibms site but not found any answer.
Yes we support running Liberty on non-IBM JVMs, including those from Oracle. As for the downloads from IBM that come bundled with Java 8 you can use that with more than the web profile (you can use the installUtility to download and install the full Java EE 7 platform onto the web profile install).

I have a task to update 8.5.5.2 web sphere to 8.5.5.14 on a windows 2008 server. I have java 1.7 already installed (and java 6 as well) and all the profiles uses it.
How ever when i try to apply fix patch using IBM installation manager, by default it's installing Java 8 which is not supported on windows 2008.
Is there a way where i can by pass java 8 and install only the fix patch (8.5.5.14) from installation manager.
Any pointer/help would be really appreciated. Thanks.
Installation Manager Screenshot:
No, WebSphere 8.5.5.14 requires Java 8, and Java 8 is not supported on Windows 2008 Server. If you must stay with Windows 2008 you can't update WebSphere past 8.5.5.13. More detail here: IBM WebSphere SDK Java Technology Edition 8.0 Minimum Supported Operating Systems
This is what IBM documentation ( https://www-01.ibm.com/support/docview.wss?uid=swg27045339 ) says, I did some shortcuts to make key points easier to notice in a long article:
In 8.5.5.14 and later, it is planned that (Java8) SDK will be required for all new installations and all updates (fixpacks).
In 8.5.5.14 (...) prior operating system releases (such as Windows 2008 (...) ) will no longer be supported.
So unfortunately what you are trying to do is not supported:
Although Java7 is still fine as a runtime environment for your servers, for example if your business application is not yet Java8 compatible, you need to have Java8 installed as a default JVM for Websphere 8.5.5.14 "internal" requirements.
You cant have IBM's Java8 installed in Windows2008, which is mandatory for Websphere 8.5.5.14, that means you cant install Websphere 8.5.5.14.
In the end, I would like to remind you, that you can upgrade to a previous release: 8.5.5.13. Version 8.5.5.13 is 11 fixpacks newer than what you already have, maybe it will suffice for your needs.
Bottom line - upgrade windows to a current version that's not 11 years old. Or, better yet, put it on Linux. WAS is great on Linux! Red Hat, Suse, OpenSuse, Fedora, CentOS are good flavors.
Our developers currently use the IBM RAD 8.5 to develop web applications (No enterprise Java beans (No J2EE), use Spring framework). The server team is planning to upgrade WebSphere from version 8 to version 9. Last I checked in the servers tab, RAD 8.5 supports WAS version 8, 8.5, and 8.5 Liberty profile. See screenshot.
Is it possible to continue to develop in RAD 8.5, and deploy to WebSphere 9 in the server environment? What kind of snag would I expect to run into? e.g. Assemble the WAR file in RAD 8.5, and deploy the WAR file in WAS 9.
Would there be any problem I should anticipate in the deployment descriptor? e.g. files like web.xml and application.xml?
Moving forward, is it better to use other IDE to do software development if we are not planning to upgrade RAD 8.5 to a newer version? Would MyEclipse(variant of Eclipse with better server support) or Eclipse IDE for Java EE Developers (oxygen) suffice? Do I also need the liberty profile?

What kind of issues should I be expecting? Or continue using RAD 8.5 would be a better option?
Here are some of the stackoverflow links I had checked already. There are pretty high level.

Thanks.
In my experience I could not use RAD 8.5 to control a v9 server. I could not use Java 8 in RAD 8.5. I would not expect RAD 8.5 to know about the newer versions of JPA, JAX-RS and other things in v9. You could continue to develop jee6 apps on a v8.5 server and then move them manually to a v9 server.
Liberty is worth a look but is not completely interchangeable. Liberty has features that traditional does not (MicroProfile) and lacks some older things that traditional has (JAX-RPC).
You might check out the WebSphere Developer Tools for Eclipse that have support for traditional v9. They're not as full featured as RAD but might be enough. More info is at https://www.ibm.com/support/knowledgecenter/en/was_beta/com.ibm.websphere.wdt.doc/topics/wdt_overview.htm
Adding to the information provided by Bruce, IBM had introduced OpenLiberty where one can deploy the war file built with RAD. Deploying to other application server (e.g. tomcatEE
) is possible, but it would require some work. OpenLiberty should be closest to the IBM Websphere in terms of setup and architecture.
Here are some links that provide more information.

We are upgrading our application and if we use Sun JDK on local it works and its failing on DEV box. we have IBM jdk on our DEV box. What is the SUN equivalent JDK that Websphere 7 has?
WebSphere 7 supports Java6 and JEE5.
However, it requires Java versions shipped with WebSphere itself. (Most are IBM's own Java SDKs, although I think the Solaris version of WebSphere might ship with Oracle's Java.)
I've been asked to get a web application running in WebSphere using RAD 8.0.1, which isn't my usual app.server or development environment.
I'm starting off simple, using the default Ajax Test Server, but from what I can see, the default for a Dynamic Web Application is Servlets 2.5. Is there something buried in the twisty little maze of config dialogs to set it to Servlets 3.0, or must I handle that manually?
IBM Websphere Application Server 8.0 supports Servlet 3.0
IBM Websphere Application Server versions 7.0 and 6.1 do not support it.
So you need to use version 8.0. If you are using Websphere Portal, then you have a problem.
IBM Websphere Portal runs on same version Application Server (though you can for instance run Portal 6.1 on WAS 7 - I ran into some problems with AJAX though). So you might be able to get Portal 7 to run on WAS 8. It's the only way in the short term.
What is the run-time environment that you use?
WebSphere 7.x does not support Servlets 3.0 and it would be supported only by WebSphere 8.0.
WebSphere 8.0 is still in beta.
Interestingly, wikipedia is a good site for the list of supported APIs by WAS.
http://en.wikipedia.org/wiki/IBM_WebSphere_Application_Server
I don't have a RAD 8 handy with me to assist but i would check and ensure that the run-time associated with the project does support Java EE 6 (and Servlets 3.0)

Websphere Application Server 7 can support servlets 3.0 if you installed Fix Pack 7.0.0.37 or later.
That shall upgrade JDK from 1.5.x to 1.6.x. Also you need to install WebSphere Application Server V7 Feature Pack for Web 2.0 and Mobile V1.1
Yesterday, I've downloaded and install the free trial version of WAS v7. The version I've downloaded is 7.0.0.9 but I need to certify my application against 7.0.0.3.
Where can I get this version?
UPDATED: It turns out that what I really needed was WebSphere Application Server for Developpers
It's working!
Now it can be downloaded from HERE
This link provides a Windows or Linux version of WebSphere 7.0.0.0 for development testing.

This link provides Fix Pack 3 for Windows (a Linux version of the fix pack is also available.)
