Based on the version of JBoss / WildFly you are using, please use the quick links below to directly go to the associated chapter:

JBoss 4.0.x and 4.2.x

In JBoss 4.x, the JMX-based remote deployer can accept URLs that point to another machine. For example (please note that the URL is "beautified" to be across lines so it is readable):

JBoss JMX-based URL deployment example 
http://10.156.216.147:8080/jmx-console/HtmlAdaptor
    ?action=invokeOpByName&name=jboss.system:service%3DMainDeployer
    &methodName=deploy&argType=java.net.URL
    &arg0=http%3A%2F%2F10.156.220.90%3A18080%2Fparuemas-1.0-SNAPSHOT.war

In this case, our JBoss server on 10.156.216.127 will connect to 10.156.220.90 via HTTP and download the paruemas-1.0-SNAPSHOT.war file. Once the file is downloaded, JBoss will automatically deploy it.

The Codehaus Cargo JBoss container uses this principle to expose your Java EE application to JBoss using an HTTP server that is started on the machine where Codehaus Cargo is currently running. That HTTP server is controlled using two parameters:

  • JBossPropertySet.REMOTEDEPLOY_HOSTNAME (i.e., cargo.jboss.remotedeploy.hostname): sets the hostname that the JBoss server will attempt to connect to. By default, the Codehaus Cargo JBoss container will automatically resolve the current machine's network name or IP address and fill this accordingly.
  • JBossPropertySet.REMOTEDEPLOY_PORT (i.e., cargo.jboss.remotedeploy.port): sets the port number on which the HTTP server will be started on the machine running Codehaus Cargo. By default, that one is set to 1 + the HTTP port for JBoss. For example, if JBoss is running on HTTP port 8080, then the default for JBossPropertySet.REMOTEDEPLOY_PORT will be 18080.

The obvious limitation you should be aware of is that JBoss needs to have direct access to the machine running Codehaus Cargo.

JBoss 5.0.x, 5.1.x, 6.0.x and 6.1.x

Starting from JBoss 5.x, JBoss has a Deployment Manager that can be used for deploying things on the JBoss server. If you really want to know how it works under the hood, you can read about this feature on the JBoss Website. If you only want to remotely deploy applications using Codehaus Cargo to your JBoss server, you can of course ignore that document.

To connect to the JBoss Deployment Manager, Codehaus Cargo uses JBoss' JMX RMI port; and that's what makes things get a bit complicated. For the connection to succeed, the following JARs need to be in the container classpath or in the current Java Thread's context classloader:

  • JBoss deployment manager JARs
  • JBoss remoting client JARs

Here is an example code for the users of the Java API:

List<URL> urls = new ArrayList<URL>();

// Add many libraries from JBOSS_HOME
for (File jar : new File(this.localContainer.getHome(), "lib").listFiles())
{
    if (jar.isFile())
    {
        urls.add(jar.toURI().toURL());
    }
}
for (File jar : new File(this.localContainer.getHome(), "common/lib").listFiles())
{
    if (jar.isFile())
    {
        urls.add(jar.toURI().toURL());
    }
}

// Create a ClassLoader contaning all these JARs
URL[] urlsArray = new URL[urls.size()];
urlsArray = urls.toArray(urlsArray);
URLClassLoader classLoader = new URLClassLoader(urlsArray, this.getClass().getClassLoader());
Thread.currentThread().setContextClassLoader(classLoader);

// Now, create the JBoss Remote container

You can also use the Codehaus Cargo JBoss remote deployer to remotely deploy to JBoss farms versions 5.x and newer. To do so, use these two properties:

  • cargo.jboss.clustered: if true, deployment is done in the farm directory
  • cargo.jboss.configuration: JBoss profile name, default name is default

JBoss socket connection bug - java.lang.IllegalArgumentException: port out of range:-1

On some Linux distributions, remote deployment may fail with an exception like:

org.codehaus.cargo.container.ContainerException: Cannot get the JBoss Deployment Manager on Provider URL jnp://localhost:44399
    at org.codehaus.cargo.tools.jboss.JBossDeployer.getDeploymentManager(JBossDeployer.java:193)
    at org.codehaus.cargo.tools.jboss.JBossDeployer.deploy(JBossDeployer.java:70)
    [...]
Caused by: org.jboss.remoting.CannotConnectException: Can not get connection to server.
    Problem establishing socket connection for InvokerLocator
        [socket://LXC_trusty_1509-a5724cdf/?dataType=invocation&enableTcpNoDelay=true
         &marshaller=org.jboss.invocation.unified.marshall.InvocationMarshaller
         &unmarshaller=org.jboss.invocation.unified.marshall.InvocationUnMarshaller]
    at org.jboss.remoting.transport.socket.MicroSocketClientInvoker.transport(MicroSocketClientInvoker.java:831)
    [...]
Caused by: java.lang.IllegalArgumentException: port out of range:-1

That is a known bug, documented in https://developer.jboss.org/message/528140 due to the fact that the host, machine or DNS name you set on your machine as an underscore (i.e., _) character in it.

To fix it, simply rename your host, machine or DNS name to not include underscores anymore; for example on Linux you achieve this by executing a command similar to: sudo hostname codehaus-cargo-ci

JBoss socket connection bug - Problem establishing socket connection for InvokerLocator

On some Linux distributions, remote deployment may fail with an exception like:

Caused by: java.io.IOException: Can not get connection to server.
           Problem establishing socket connection for InvokerLocator
           [socket://host:32342/]

That is a known bug, documented in https://developer.jboss.org/docs/DOC-16380, and the solution presented on that document is to use a cron job as the root user to fix the file when it gets broken.

First, create the correct version of /etc/hosts and save it somewhere, such as /etc/hosts.fixed, and populate it with the following contents (replace myhost with the hostname of your computer, as reported by the hostname command, and the correct IP assignment, as reported by ipconfig):

/etc/hosts.fixed 
127.0.0.1 myhost localhost localhost.localdomain
::1 myhost localhost6 localhost6.localdomain6
127.0.1.1 myhost
## (optional entry); update if assigned a new address from DHCP
192.168.1.5 myhost

## The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost  ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Important: If possible, enter your hostname with both the "basic" hostname and the fully-qualified domain name.

Next, create a script named /etc/restore-etc-hosts.sh to replace the /etc/hosts file if Network Manager breaks it:

/etc/restore-etc-hosts.sh 
#!/bin/sh

if [ `grep -c NetworkManager /etc/hosts` -eq 1 ]; then
   cp /etc/hosts.fixed /etc/hosts
fi

Finally, setup a cron job to run this script as often as you like. We recommend every couple of minutes.

*/3 * * * * /etc/restore-etc-hosts.sh

Once the /etc/hosts file is corrected, restart JBoss AS and run the tests again. Your socket connection error should be gone!

JBoss 7.0.x onwards / WildFly 8.x onwards

The same instructions for JBoss 5.x, 5.1.x and 6.x also apply for JBoss 7.0.x onwards as well as WildFly 8.x onwards, with some differences:

  • The JAR files to include are different
  • JBoss (Application Server) as well as JBoss Enterprise Application Platform (EAP) 6.x use the cargo.jboss.management-native.port port
  • All WildFly versions as well as JBoss Enterprise Application Platform (EAP) 7.x use the cargo.jboss.management-http.port port

The following examples detail these differences.

Here is an example code for the users of the Java API:

/**
 * Add all JARs in a folder in the list of files (recursive).
 * @param folder Folder to recursively scan.
 * @param files List containing all files.
 */
public static void addAllJars(File folder, List<URL> files) throws Exception
{
    if (folder.isDirectory())
    {
        for (File file : folder.listFiles())
        {
            if (file.isFile() && file.getName().endsWith(".jar"))
            {
                files.add(file.toURI().toURL());
            }
            else if (file.isDirectory())
            {
                addAllJars(file, files);
            }
        }
    }
}

List<URL> urls = new ArrayList<URL>();

// Add many libraries from JBOSS_HOME/modules
addAllJars(new File(this.localContainer.getHome(), "modules"), urls);

// Create a ClassLoader contaning all these JARs
URL[] urlsArray = new URL[urls.size()];
urlsArray = urls.toArray(urlsArray);
URLClassLoader classLoader = new URLClassLoader(urlsArray, this.getClass().getClassLoader());
Thread.currentThread().setContextClassLoader(classLoader);

// Now, create the JBoss Remote container
