Not able to connect to JMX remotely for PocessBuilder program

We are getting problem in connecting through jmx via remote.we run a job through ProcessBuilder by program

Code Snippet:

param ="-Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=A.B.C.D -Dcom.sun.management.jmxremote.port=9875 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false "
ProcessBuilder pb = new ProcessBuilder("java", param,"-cp", jobArtifact.getAbsolutePath());          
pb.command().add("org.springframework.batch.core.launch.support.CommandLineJobRunner");
final Process process = processBuilder.start();

Process is being started but when we try to connect it with jconsole via remote it's not connecting... and connection failed message is coming:

Remote connection URL: service:jmx:rmi:///jndi/rmi://A.B.C.D:9875/jmxrmi

What we have tried:

  1. Added -Djava.rmi.server.hostname=A.B.C.D and
    -Dcom.sun.management.jmxremote.local.only=false
  2. ProcessBuilder.getEnv() and added our environment properties.

  3. When we are running the same program via command prompt:

    java -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9875 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -cp C:\jobs\abc.jar org.springframework.batch.core.launch.support.CommandLineJobRunner

    it is running and able to connect with jmx via remote with the same URL mentioned above.

Any suggestions/workaround would be welcome!!!

Solution

  • Each -D option needs to be a separate parameter to the ProcessBuilder:

    ProcessBuilder pb = new ProcessBuilder("java",
    "-Dcom.sun.management.jmxremote",
    "-Djava.rmi.server.hostname=A.B.C.D",
    // etc. etc.
    "-cp", jobArtifact.getAbsolutePath(),
    "org.springframework.batch.core.launch.support.CommandLineJobRunner");
final Process process = processBuilder.start();

    Your current code, with all of them concatenated together into one parameter, is essentially setting one property named "com.sun.management.jmxremote -Djava.rmi.server.hostname" to the value "A.B.C.D -Dcom.sun.management.jmxremote.port=9875 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false " (including the trailing space).
