    I have absolutely no clue what "prevision" is nor does a Google search show anything I could understand.

    However, adding formula functions is done by implementing two interfaces:

    for the actual function and

    for the metadata of that function.

    After implementing these you then have to register the functions in a file called "". Place a new properties file in the root package of your jar and we will pick up your new implementation during the bootup of the reporting engine.

    Have a look at the sources for the "libformula" project to see some sample implementations of the functions we provide.
