    I am getting this message from B4J so it is in the right section and your suggestion does not seem to apply......

    Do you have JavaFX Scene Builder installed?

    Out of curiosity, will it run in release Mode?

    Your firewall is probably blocking the connection. Try to temporary disable it and see if it connects.

    "CORRECTION" per Erel there is a rapid debugger in B4J it is the same as B4A.
    In B4A there is a drop down for rapid debug mode I was not aware of this in B4J because its not a drop down. Normally I have seen the above error in B4A. My apologizes for misinforming.

    Do B4J apps run on Android smart phones?

    Is there a B4J bridge app (as in B4A) to link an Android smartphone to a PC ?

    How do I import a library into B4J?

    See this tutorial: What is B4J?

    In the same way as in Basic4android. You copy the library files to the libraries folder and select it in the libraries tab.

    Very nice but as you say B4J creates as Jar file so its is Java, why not use Netbeans and java directly?

    Not sure that I understand the logic here. A jar file is similar to an exe file. You can also say "C++ creates an exe file so why not use Assembler".

    B4J allows you to easily create desktop, server and web apps. With the same language as B4A and with very similar libraries.

    If you are an experienced Java developer (with server and websockets experience) then you can use Java instead of B4J. If not then it will be easier to use B4J.

    To be fair Erel, even as an experienced Java developer with server and websocket experience, it's still easier to use B4J :)

    I agree (and I'm experienced in both frameworks ;) ).

    thanks Erel and everyone else who has contributed to these b4x projects. As someone who has been stuck on vb6 syntax for years and found it challenging to learn new languages, I now feel like the sky is the limit as I transition away from Windows desktop apps which are so 90s into WebApps and Mobile. All while working with the VB syntax I am very familiar and comfortable with. Thank you Thank you ThankYOU :):):)

    I have to say, I would pay for a "pro" version that somehow brought the two dev environments closer together. The ability to build both Windows, mac, and android apps from the same place would easily add value.

    You see it in the likes of YoYo Game Maker and it makes developing one app for all platforms much more straight forward. Whilst I appreciate it wouldn't be 'straight forward' as such, some how bringing the dev suits together and charging, say, a few hundred dollars...well...you'd get my money.

    Hi Erel,

    Years ago I developed in Java 2 and other languages. This is way easier and as you stated, the B4A and B4J coding is almost identical!
    Porting from B4A to B4j and visa versa is absolutely cool and easy - Hardly any modifications at all. Copy and Paste is MY FRIEND!
    There are other ways, too using the library compilations functions.
    Thank you Erel and all who contributed to B4X. Tooo many to list!

    Mark
