[wildfly-dev] HTTP API support for plain JBoss-CLI commands

[John Mazzitelli]

FYI: This might be useful... Hawkular has a DMR client library built on top of the ModelNode/ModelControllerClient stuff - it is meant to be a more strongly typed library that helps you not have to know how to do all the low level ModelNode stuff to do basic things (though it still allows you to send custom ModelNode requests).

It's here:

https://github.com/hawkular/hawkular-agent/tree/master/hawkular-dmr-client/src/main/java/org/hawkular/dmrclient

released here:

https://repository.jboss.org/nexus/content/groups/public/org/hawkular/agent/hawkular-dmr-client/

which includes javadoc/source jars.

Doesn't give you "everything", but it has the basics and then some for what we need it for. This lib will get built out as we need more functionality.

Example usage:

ModelControllerClient mcc; // get this somehow - usually by ModelControllerClient.Factory.create
CoreJBossASClient client = new CoreJBossASClient(mcc); // use one of the provided JBossASClient subclasses
String dataDir = client.getAppServerDataDir(); // gets the app server's data directory
ModelNode node = client.readResource(Address.parse("/deployment=foo.war")); // gets info on foo.war
...
DeploymentJBossASClient dClient = new DeploymentJBossASClient(mcc); // to do deployment specific things
dClient.enableDeployment("foo.war");
...

etc, etc... a bunch of subclasses to JBossASClient that lets you do specific things to things like datasources, logging, web connectors, etc.
