jboss cli java client remote command

jsaura Aug 1, 2013 4:12 AM

Hello

i have just developed a little java program ( i am not developer i am sysadmin )

is working great, i connect to remote controller but the problem i am facing is that i cannot send commands like "ls /host=master/server-config=server-one" cause it throws and exception saying its impossible to translate it to a command ..

what i want to do is that my program connects to controller to check if a server is started or not and if not start it on a jboss domain setup, pretty easy at first sight ....

why can´t i send this kinda commands using the jboss cli api? is there a way of doing this using the api?

in the same way i cannot start o stop a server doing

/host=master/server-config=server-one:stop

/host=master/server-config=server-one:start

all this commands work perfectly if i connect to console using de jboss-cli.sh, but it seems i cannot send this command using my code that uses jboss cli jars ... for example

./jboss-cli.sh --connect --controller=10.12.0.108:9999 --command='ls /host=master/server-config=server-one' | grep 'status='

status=STARTED

thanks in advance

Show you code. Working with the libraries are usually a bit more low-level (nodes and stuff) but I think there are helper functions somewhere(tm) that the CLI uses that parses stuff like that directly.

hi, first of all thanks for answering

this is my code

i do not enclose all xml conf parse i have done to read controller ip, port , pass etc etc

connection part, working fine

public void setUp() throws Exception {

                      ctx = org.jboss.as.cli.CommandContextFactory.getInstance().newCommandContext(this.usuario, this.pass.toCharArray());
                       ctx.connectController(this.ip, Integer.parseInt(this.puerto));

          }

sending command

public void testExecuteCLICommand() throws Exception {
                    String CLIcmd = "ls /host=master/server-config=server-one";

ModelControllerClient client = ctx.getModelControllerClient();
ModelNode commandRequest = ctx.buildRequest(CLIcmd);
ModelNode result;
result = client.execute(commandRequest);
System.out.println(result);
}

this throws this exception

org.jboss.as.cli.operation.OperationFormatException: The command does not translate to an operation request.

maybe is just i am using the wrong method to send this commands, seems it expects an operation

i also used dmr method

ModelNode deployRequest = ctx.buildRequest("ls /host=master/server-config=server-one");

no luck either

Hi,

ls is high level command that only standalone CLI understands.

you should run

ModelNode deployRequest = ctx.buildRequest("/host=master/server-config=server-one:read-resource");
which is equivalent in dmr syntax

ahhh, ok i thought i could pass whatever command this way, i see that i need to pass it in other way

that works for stopping and starting the server, but i do not find anyway to check if is up or down with this dmr syntax

read-resource does not show me the status

/host=master/server-config=server-one:read-resource
{
    "outcome" => "success",
    "result" => {
        "auto-start" => true,
        "cpu-affinity" => undefined,
        "group" => "main-server-group",
        "interface" => undefined,
        "name" => "server-one",
        "path" => undefined,
        "priority" => undefined,
        "socket-binding-group" => undefined,
        "socket-binding-port-offset" => 0,
        "system-property" => undefined,
        "jvm" => {"default" => undefined}
    }
}

any idea how should i ask to see if is started or not? i do not find any combination to check if its up or not

thanks !

UPDATE :

nevermind, i found it

/host=master/server-config=server-one:read-resource(include-runtime=true)
{
    "outcome" => "success",
    "result" => {
        "auto-start" => true,
        "cpu-affinity" => undefined,
        "group" => "main-server-group",
        "interface" => undefined,
        "name" => "server-one",
        "path" => undefined,
        "priority" => undefined,
        "socket-binding-group" => undefined,
        "socket-binding-port-offset" => 0,
        "status" => "STARTED",
        "system-property" => undefined,
        "jvm" => {"default" => undefined}
    }
}

just need to inclide runtime=true

thanks guys!
