    How can I write a small java to sent request to the device and get back its response?

  • Check out the source code in the test package.

    symbol : variable read
    location: class com.serotonin.bacnet4j.test.Test2

  • Yes. It doesn't know what the symbol "read" is.

  • Yes, you are right.
    I took out the "read" object.
    Now, I put it back,and (following ) this is the actual error (my first error) while doing compling.
    It seems some classes missing in the package. cannot access com.serotonin.util.queue.ByteQueue
    class file for com.serotonin.util.queue.ByteQueue not found
    ReadPropertyRequest read = new ReadPropertyRequest(new ObjectIdentifier(
    ObjectType.device, deviceId),

  • seroUtils.jar is included in the package. You need this in your classpath.

  • in the package, we use a lot of com.serotonin.util.queue.ByteQueue;but
    where i can find the source code for
    Or, what is method or function for it?

  • ByteQueue is in the seroUtils.jar file, which is not open source. You shouldn't really need it since it's just a utility class anyway.
