    Hello B4A Family.

    I have taken a leap to try to understand the JavaObject in B4a
    I have read Erels' tutorial for the JavaObject using Picasso over and over.

    Now I know the leap i've taken is probably huge but I want to see if I can integrate the RabbitMQ
    with a project I have. So here is my question.

    I got all the Jars' in B4A - tested all sorts of invocations and objects and JavaObjects just to get myself a bit more confused. If I could just get an example of how the below could be done in B4A I would appreciate it IMMENSELY !

    ConnectionFactory factory = new ConnectionFactory();
    Connection conn = factory.newConnection();
    Preferably i like to use

    ConnectionFactory factory = new ConnectionFactory();
    Connection conn = factory.newConnection();
    Im able to get the "class" initializedStatic but when I try to run any of the methods to set the properties i get the error

    java.lang.IllegalArgumentException: expected receiver of type com.rabbitmq.client.ConnectionFactory, but got java.lang.Class<com.rabbitmq.client.ConnectionFactory>
    It goes without saying I am not a Java person - but what better way to learn than to jump in the deep end.

    The javadoc is located at :

    Again to anybody that could give me boost i would be so greatful!

    Kindest regards

    Please post your code.

    You should use InitializeNewInstance not static.

    @Erel - Thanks for the reply - I tried that and got it working.

    @rboeck - Thank you for the link! Looks like this will be a solution for my project!

    Thanks so much!
