Which component of Mule 4.1 replaces Mule 3.9 <timer-interceptor> ?
None. Mule 3 interceptors are not supported in Mule 4. You might rbe able to replace them somewhat with custom policies, as mentioned in the migration documentationhttps://docs.mulesoft.com/mule-runtime/4.1/migration-core
The reason is that Mule 4 architecture is very different in thread management and it doesn't allow the interceptors implementation.

I am using Mule 3.9 with Anypoint studio 7.2 for API development. After my functionality developed I was able to export to a Jar file which I was supposed to run on my hardware which doesnt support x64 architecture.
I got error of not supported architecture. So I am looking for solution in 2 ways.
As hardware architecture cant be changed, is there any way to still run Mule program on it without using Mule runtime environment.
Using exported Jar file is it possible to use it only without Mule installed on my hardware machine.
Thanks in advance.
As per comment See error message,when tried to run in Docker also.
Mule uses the Java Service Wrapper to bootstrap the Mule runtime. At this time the version of the wrapper included with Mule previous to Mule 4.4 doesn't support aarch64 as an architecture, only 32 bits ARM (armhf). At this time only Mule 4.4 Enterprise Edition seems to has compatibility with armhf-64. You should try that version to see if aarch64 is recognized as armhf-64.
Also note that Studio 7.x is not compatible with Mule 3.x applications so it is not possible to use it to develop a Mule 3.9 application. You are saying that the deployment file is a jar file so it is clearly a Mule 4 application. A Mule 4 application can not be deployed to a Mule 3 server, they are not compatible.
Is OAS 2.0 or 3.0 specification is supported in Mule runtime 3.9? If yes, please let me know the configuration and requirement.
Only Mule 4.x and Studio 7.x support OAS 2.0 and OAS 3.0. Technically speaking it is the APIKit module for Mule 4 that support OAS rather than the Mule runtime. That version of APIKit is not compatible with Mule 3.x.
How to add request-reply scope to the mule studio 3.5.0. Not able to see request-reply scope in the pane. could you please help me out on this?
The studio version you are referring to seems to be pretty old.Would be great if you could update to 5.X.
You may also try modifying the xml explicitly, in case you are deploying the code on a decoupled EE server.
<request-reply doc:name="Request-Reply"/>
Documentation says that:
The Request-Reply scope has been available since Mule Runtime version
3. An icon was added for this in the 3.5 version of Anypoint Studio
So in order for you to get an icon you need to install the 3.5 or above version of Anypoint Studio.
we have a saga that calls numerous handlers. I want to start the migration from 2.6 to 4.0 so I have upgraded one of the handlers to 4.0. If I deploy this handler alongside the other 2.6 handlers and with a 2.6 saga that calls both types of handlers is there going to be trouble? Is this even possible?
Thanks
take a look at the NServiceBus 4.0 release notes
it states that 4.x is not compatible with 2.x...
upgrading to 3.x and then 4.x seems like a less painful option
What is the simplest way to convert EJB 2.0 (WebLogic 8.1) project to EJB 3.0 (OAS or WebLogic etc)?
I found just this article "Converting an EJB 2.0 Entity Bean to EJB 3.0", which could automate this process, but forced to do too much manual manipulations.
IMO, you can't really convert an EJB 2.1 project to an EJB 3.x project. You can however migrate and this is a project by itself. Some more resources:
Migrating EJB 2.1 Entity and Session Beans to EJB 3.0
Migrating EJB 2.x applications to EJB 3.0
Use Intellij's "Apply EJB 3.0 Style" tool. It automates a lot of the painful steps, especially replacing ejb-jar.xml configurations with annotations. Migration can be applied incrementally (you select the ejb's) or all at once. It does other steps for you as well; details here:
http://www.jetbrains.com/idea/webhelp/migrating-to-ejb-3-0.html
I found this to be immensely helpful and worth the price of an Intellij license all by itself for the number of hours it saved me. I did not find anything comparable in either Eclipse or Netbeans.
An old, but helpful, additional resource:
