WildFly CLI command to reload a deployment

Question

I can restart the whole WildFly server running the following Java code. But I want to just reload a deployment called 'test.war'. How could it be done?

public void flushall() throws IOException {
    Runtime.getRuntime().exec(
        "cmd /c start C:\\wildfly\\bin\\jboss-cli.bat --connect /subsystem=datasources/data-source=FirebirdPool/:flush-all-connection-in-pool "
    );
}

Answer 1

Just call the redeploy operation on the correct deployment node.

The CLI command looks like:

/deployment=test.war:redeploy()

It means in your case:

"cmd /c start C:\\wildfly\\bin\\jboss-cli.bat -c /deployment=test.war:redeploy"

Answer 2

To restart JBoss or WildFly using command line interface (CLI):

$JBOSS_HOME/bin/jboss-cli.sh -c --command=:shutdown(restart=true)

The same command without the restart parameter will simply shutdown JBoss and WildFly:

$JBOSS_HOME/bin/jboss-cli.sh -c --command=:shutdown

To reload JBoss and WildFly configuration using JBoss CLI:

$JBOSS_HOME/bin/jboss-cli.sh -c --command=:reload

There is a difference between :reload and :shutdown(restart=true) commands.

• :reload shuts down JBoss and starts it again without JVM restart.

• :shutdown(restart=true) restarts whole JVM process of the JBoss server.
