Deployment Order Issues with multiple EARs

[acxsjones]

I have 3 ears, and I need to have one of them deployed before the others, what is the best way to do this?

Unfortunately there isn't any nice solution. But a bit of a hack is provided in conf/jboss-service.xml

You need to comment out the DeploymentSorter below, and use the PrefixDeploymentSorter commented out just below it, like this.

<!--
org.jboss.deployment.DeploymentSorter
-->
org.jboss.deployment.scanner.PrefixDeploymentSorter

Now on deployment you'll have to prefix your ears with numbers:

001_common.ear
002_app1.ear
003_app2.ear
etc...

This will ensure common.ear will be deployed before any of the other two (but AFTER any ear without the number prefix)

Personally I thought this was such an ugly solution that I first refused to use it. Until I had no choice any longer, and it works fine. But it's rather disappointing there isn't a way to put order information in the jboss.xml files, it seems so much more logical.

Something like:
common.ear,common.sar,whatever.jar
to indicate that other archives need deploying first shouldn't have been so hard to make I would have thought.

you would really be better off revamping how you are doing your deployment packaging so you can break the dependencies entirely.

the PrefixDeploymentSorter will work, but it can become a pain if you need to keep renaming files if the deployment order changes.

if you are deploying a bunch of thirdparty libraries together in a single ear, consider dropping them in the "lib" directory or package them inside a sar so they are always deployed first.

also, since jboss supports "russian-doll" packaging, you could also wrap the ear that needs to be deployed first inside a sar archive, so that it gets deployed before anything else.

Hi all,
I guess you need a jboss-service.xml file in the .sar archive.
How does it look like if we want to put an .ear in a .sar?

Could you post an example of it?

Thanks.
