B4J Question how to create library with B4J

[Roberto P.]

I want to create a library with B4J, containing generic functions for use with another Java program.

I did two tests with new project "UI" and "NON UI".

When I try to generate the library from the following error:

Compiling code. error
No modules to compile.
Compilation:
main


I try to remove the main module from the project menu but it does not allow it.


can you tell me how to do it?

thank you

Create a Class with the functionality, compile it to a library and use the compiled library in your projects then.

 

[Roberto P.]

OK thanks

but I would like to create more classes in the project and save everything in one library. So I have to create a library for each class!

 

[DonManfred]

So I have to create a library for each class!

yes.
Or you are using one class which does contain all

Edit to add: Seems i was wrong. Sorry

yes.

Are you sure? I thought everything in the project, except the main class, was compiled to the library.

No problem!

No!

As alwaysbusy already wrote, all modules in the project will be in the library except the Main module.
You can set #ExcludeFromLibrary on top of a module to exclude it from the library.

 

[Roberto P.]

ok, thank at all

Is the other java program created by b4j or is it a native java program?

 

[Roberto P.]

I created the library. But I can not use it from a program written in Java. Can the B4j libraries only work for B4J \ B4A?

Yes with B4J but not with B4A.
