The lab results are in!

*Test setup*

I created a fresh Fedora 17 installation on a virtual machine, installed JBoss AS 7 using yum (yum install jboss-as), installed JBoss Developer Studio 5 Beta 3 and gave another crack at these use cases.

*Preparing a user instance with jboss-as-cp*

I'm happy to report that jboss-as-cp works as expected. Here's what I did to create a test a new "user instance":

+*Create instance:*+
*
*
mkdir $HOME/applications
jboss-as-cp -l $HOME/applications/jboss-as-user-instance -c standalone-web.xml


+*Start instance:*+
*
*
JBOSS_BASE_DIR=$HOME/applications/jboss-as-user-instance /usr/share/jboss-as/bin/standalone.sh -c standalone-web.xml


+*Verify it's running:*+
*
*
links http://localhost:8080


With that working, I switched over to JBoss Tools to setup the server runtime to work against that externally managed instance.

*Deploying to the user instance from JBoss Tools*

I began by defining a new server runtime. This can be done one of two ways:

1. Pointing the JBoss Tools runtime scanner at /usr/share/jboss-as and letting it detect and create both the server runtime and server
2. Adding a new JBoss AS 7.1 server runtime, setting the home directory (of the runtime) to /usr/share/jboss-as and adding a server to match

It's important to check the box "Server is external managed. Assume server is started." (for this part, at least).

By default, JBoss Tools is going to use the JBoss deploy folder (/usr/share/jboss-as/standalone/deployments) to perform deployments. You can see this by double clicking on the server in the Servers view and switching to the Deployment tab.

That's obviously not what we want. We need JBoss Tools to deploy into our user instance ($HOME/applications/jboss-as-user-instance/deployments). In theory, this is done one of two ways:

1. Checking the radio button "Use workspace metadata"
2. Checking the radio button "Use a custom deploy folder"* Deploy Directory: /home/username/applications/jboss-as-user-instance/deployments
* Temporary Deploy Directory: /home/username/applications/jboss-as-user-instance


In addition to changing where JBoss Tools deploys the application, this also adds a deployment scanner entry in standalone-web.xml:

Case #1:
<deployment-scanner name="JBossToolsScanner1" path="/home/username/workspace/.metadata/.plugins/org.jboss.ide.eclipse.as.core/JBoss_AS_7.1_Server/deploy" scan-interval="5000"/>

Case #2:
<deployment-scanner name="JBossToolsScanner1" path="/home/username/applications/jboss-as-user-instance/deployments" scan-interval="5000"/>

Save the configuration and start (connect to) the server by clicking the play button in the Servers tab.

In theory, I should now be able to import a web project (such as numberguess from the JBoss quickstarts), drag it to the server and it should deploy. However, all I get is #fail.

JBoss Tools is copying the folders into the deployment directory specified in the server configuration, but it's failing to copy any files. Here's a listing showing what it does copy:

I have no clue where it's trying to copy the files, but clearly it's trying to put them someplace it shouldn't. This indicates to me it's trying to write files outside of my home directory (it's implausable that a file write would fail inside my home directory, where it should be copying the files).

I hypothesize that JBoss Tools (or something in WST) is not properly sandboxing the deployment directory from the installation directory.

*Controlling the user instance from JBoss Tools*

With a bit of tweaking, I was able to figure out how to get JBoss Tools to control the user instance so that it works just like a normal server inside of Eclipse.

* Delete the existing server, then add a new server as before. This time, keep the box "Server is external managed" +unchecked+.
* Switch to the Deployment tab and check either "Use workspace metadata" or "Use a custom deploy folder" as explained above
* Switch back to the Overview tab and click on "Open launch configuration"
* Uncheck the box "Always update program arguments related to the runtime"
* In the Program arguments textarea, make sure the --server-config=standalone-web.xml
* In the VM arguments textarea, remove any properties that contain the path /usr/share/jboss-as and add these properties: -Djboss.home.dir=/usr/share/jboss-as -Djboss.server.base.dir=${env_var:HOME}/applications/jboss-as-user-instance
* Click OK
* If necessary, save the Server configuration

Make sure JBoss AS is not running in a terminal. Then click on the play button in the Servers tab. You should see JBoss AS starting up in the Eclipse Console tab.

Unfortunately, deployment still fails with the same error as above. How the server is started seems unrelated to the deployment problem.

*Conclusion*

We remain at an impasse until we can figure out why JBoss Tools (or WST) is not properly copying the files to the custom deployment directory.

(If there is a way to get more verbose information from the logs, let me know and I'll report that information).

*Suggestions*

I like the idea of jboss-as-cp, but I don't think it has the right name. I'd like to propose the following alternatives:

* jboss-as-instance (consistent with the equivalent command for tcServer)
* jboss-as-create-instance (a bit more explicit about what it's doing)
* jboss-as-new-instance (a bit shorter, just as clear)*
* jboss-as-create (implies instance, if we really want to keep it short)

* my preferred choice so far

It would be nice if JBoss Tools could perform the setup done by jboss-as-cp. It's not necessary to use the jboss-as-cp as it's just a few copy commands. I envision this as another checkbox in the Server setup wizard. I don't think this is specific to Linux, so it's reasonable to make it a general option when defining a JBoss AS 7 server.
