Hi Luan,

try this:

declare namespace java = "java:java.lang.String";

let $string := 'Format string: %1$d - %2$s'
let $i := 1
let $j := 'text'
let $args := ($i, $j)

return java:format($string, $args)

Best regards
Johannes

Hello all,
    How can I call a method with variable arguments in BaseX with Java binding? I am trying to do this:

        let $string := 'Format string: %1$d - %2$s'
    let $i := 1
    let $j := 'text'
    return Q{java.lang.String}format·java.lang.String·java.lang.Object*($string, $string, $i, $j)

However, I got the error: [XPDY0002] {java.lang.String}format·java.lang.Stri...: Context is undeclared.
Thank you for your time.
