How to register Services to Mule ESB at runtime

[Denis Bessmertnyj-3]

Hi folks,

It is unclear from documentation, is it possible to register Services to Mule ESB at runtime,
for exmample invoke some sort of java methods or maybe Mule has web-services interface for such proposes. 

Or maybe via JMX?
 
Thanks for answer,

Hi Denis,

Mule supports dynamic component registration by registering and manually wiring the appropriate service, component, routers and endpoints using the transient registry.

For examples and related JIRA issues check the links mentioned in this article:

Hi Dimitar,

 

I have read your article, but it is not clear after reading does Mull

supports dynamic component registration and how to use it, if yes.

May you show me some examples or something else.

 

Thanks,

Dimitar,

 

And it is interesting that in your letter you write that it is possible,

but in article I see

 

"Usually I write about how to implement stuff with Mule, but this time I'm going to write why Mule might not be your best choice if your use-case is anything like above."

 

So, does Mule support it?

Hi,

I think user can do that with mule, but that's not the recommendation.

Denis,

Dynamic components are supported, but more cumbersome than need to be, which is the main topic of my write up, here are the two examples that I've linked to:

http://fisheye.codehaus.org/browse/mule/branches/mule-2.0.x/examples/loanbroker/esb/src/test/java/org/mule/example/loanbroker/esb/LoanBrokerEsbConfigurationBuilder.java?r=11569

http://fisheye.codehaus.org/browse/mule/trunk/mule/modules/scripting/src/test/resources/mule-config.groovy?r=9093

They show you how to bootstrap Mule instance by manually wiring and adding the components. You can also add, start, stop and dispose services any time given MuleContext instance. To obtain a MuleContext, you need to implement MuleContextAware interface or something like this. From the context, you need to obtain a registry and register or lookup your beans from there, then you wire them by using setters and finally you start your service. Let me know if it's not clear, I can post some code when I'm back to work.

Right now Mule focuses on the mediator and ETL scenarios which typically are implemented by static component graph and their support for dynamic components is suboptimal (possible, but vebose). The JIRA issues in the article, if implemented, would simplify some common cases that I have encountered. I urge you to take a look and vote, so we can let the Mulesource guys know that there is demand for these features.

Dimitar,

 

We need the possibility to register Dynamic components as usual, i.e. for example put xml file to config directory while

Mule already running and Mule should register new Service at runtime according to new xml.

Because we also need the possibility that after Mule restarting all our adding changes to Mule during runtime should be saved.

So, as I understand it is not possible with Mule?

No, this kind of dynamism is not possible right now. The capability to update the component graph from configuration file without restarting the container is being tracked as the "Hot Deploy" feature, scheduled to be one of the major topics for Mule 3 (the other major topics are transparent clustering and failover).

Remembering the settings should be achievable by using persistent JMX parameters (I've never done it myself and I'm not sure how robust is the default implementation)
