Can I use Weblogic 10.3 to build applications that run on WebLogic server 9.2? - oracle

I have WebLogic 10.3 installed (Server, Workshop and Portal).
However, some of the legacy service applications are deployed on WebLogic 9.2.
I have noticed that after using Ant to build the service library, I get an EBJ stub named ABCD_be9p7l_EOImpl_1030_WLStub.class.
Building it from WebLogic 9.2 gives ABCD_be9p7l_EOImpl_922_WLStub.class.
My question is, if I deploy the 10.3 one in the 9.2 server, will there be any compatibility issues that will stop the services from running?
If there is, is there any way that I can use WebLogic 10.3 to build applications that run on 9.2?

Read "Compatibility Statement for Oracle® WebLogic Server 10g Release 3 (10.3)" document:
Oracle attempts to support binary and source-level compatibility between the current version of WebLogic Server and all versions as far back as 8.1 in the areas of persistent data, generated classes, and API compatibility. In some cases, it is impossible to avoid incompatibilities.
and "Upgrading WebLogic Application Environments" article:
Application environments that run with WebLogic Server 10.3 can interact with application environments built on WebLogic Server 7.0, 8.1, 9.x, or 10.0.
Most existing WebLogic Server applications can be run without modification in the new WebLogic Server 10.3 application environment. You should review the compatibility information described in WebLogic Server 10.3 Compatibility with Previous Releases to determine whether any feature changes affect the applications in your environment. If your application uses APIs that have been deprecated or removed, then you may encounter warnings or exceptions at run time.

WebSphere 9 upgrade with RAD 8.5

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?
https://developer.ibm.com/wasdev/downloads/liberty-profile-using-eclipse/
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.

Websphere Application Server v9.0 supported with which version of Rational Application Developer?

can someone help me, I'm trying to work with Websphere Application Server 9.0 but I need to work on IBM Rational Application Developer IDE for the use of sqlj. I tried to install IBM Rational Application Developer IDE version 8.0 but Websphere Application Server 9.0 is not supported with this IDE. Do I need to install IBM Rational Application Developer 9.0 IDE to work with Websphere Application Server 9.0? Or is there any other IDE that supports Websphere Application Server 9.0 and sqlj scripts both.
According this IBM KnowledgeCenter for IBM Rational Application Developer for WebSphere, it looks like RAD v9.6 is the lowest version to support Websphere Application Server 9.0.

Will lastest websphere liberty full platform run oracle java 8?

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).

Configuring WebSphere Commerce Developer 6.0 to use WebSphere Application Server 6.1

Has anyone successfully configured WebSphere Commerce Developer 6.0 to use WAS 6.1 and RAD 7.0?
I'm working on a site implemented with IBM WebSphere Commerce Developer 6.0. In production the site runs on WebSphere Application Server 6.1, which is officially supported. We'd like to run our local developer environments on WAS 6.1 as well, but the migration instructions cover only stand-alone servers. Commerce Developer is limited to WAS 6.0 according to the documentation below:
http://publib.boulder.ibm.com/infocenter/wchelp/v6r0m0/index.jsp?topic=%2Fcom.ibm.commerce.admin.doc%2Ftasks%2Ftmgwas61.htm
We're hoping to be able to leverage Java 5 support and other features of WAS 6.1 while staying on WebSphere Commerce Developer 6.0. We have some portions of the code developed using Java 5, but currently we have to deploy this code to a stand-alone server to test, which is less than ideal.
Nope.. can't be done. The issue is that the runtime and tooling is all linked together.

Using Servlets 3 in IBM RAD 8?

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
