Unable to start a Bloomberg session

Question

I'm currently trying to connect to the Bloomberg API but after trying for a day still not able to get it running.

Below is sample code from the API Guide, the part where I keep getting "Could not start session." when trying to connect.

public static void main(String[] args) throws Exception {
    SessionOptions sessionOptions = new SessionOptions();  
    sessionOptions.setServerHost("localhost"); // default value 
    sessionOptions.setServerPort(8194); // default value
    Session session = new Session(sessionOptions);
    if (!session.start()) {
        System.out.println("Could not start session.");
        System.exit(1);
    }
    if (!session.openService("//blp/refdata")) {
        System.out.println("Could not open service " +
                           "//blp/refdata");
        System.exit(1);
    }
}

I also tried the async example available in the guide, but no luck as well.

Is there anything that I missed in order to use the API? Or if I have to apply for an account in order to use the API, please do let me know :)

Answer 1

Your program runs fine on my machine. The few things you should check:

• Are you on a Bloomberg terminal machine? (I assume you are using the desktop version)
• Do you have a Bloomberg session open?
• Is the bbcom.exe process running?

Just read the last line of your question: you need to have a Bloomberg account to be able to use their API and retrieve data.

Thanks for you reply! Please spare my ignorance... - I test the code on Ubuntu 10 and OSX Lion - What is Bloomberg session? The session we open in the code? - I'm on Unix base machine, bbcom.exe seem wont be able to run on it I do have an Bloomberg account (my client does), is there a docs somewhere mention how to set it up? – Burt

By session, I mean that you need to have a BB terminal open. Best thing in your case would be to call BB support, they should be able to get you started. – Marriott

I think that's the only way I can take, thanks for giving advice :) – Burt

My problem was solved after running "bbcomm.exe"
