    Hello Michael,

    hopefully you can help me farther. I did not succeed to run a Java
    method.

    I have tried to read the password from the file system, with xml
    something like you wrote, it worked fine. :)
            <login userName="username" passwordLocation="url"
    passwordSource="file:///home/lenka/password/"/> (where in password is a
    plain text)

    However to run a Java does not work. I have tried with following
    options:
    <login userName="username" passwordLocation="executable"
    passwordSource="com.lenka.Password"/>
    <login userName="username" passwordLocation="executable"
    passwordSource="java com.lenka.Password"/>
    <login userName="username"
    passwordLocation="executable"passwordSource="java
    file://home/lenka/Password"/> (with the absolute address, to
    Password.class)

    package com.lenka;

    public class Password {

            public static void main(String[] args) {
                    System.out.println("password");
            }
    }

    Any hint will be appreciated.
    Regards
    Lenka

    Hi Michael,

    Thank you very much for the answer. Yes, I would like to use the Java
    function. But I think I understand it now.

    Thank you a lot
    Lenka

    Hi Lenka,

    The passwordSource in the XML is overloaded in this case and should
    reference the executable to run along with any parameters it needs.
    It looks to me like you are trying to run a Java method? If so,
    you'll need to have a "java ..." command there. I also suspect you
    might could use the URL method. I've used that in the past to read an
    encrypted password off the filesystem. For that, part of my XML
    looked something like:

    <login userName="username" encoderClass="my.TripleDESPasswordEncoder"
    encoderSalt="94VW4MOreXfvbSbB6ewbfp3XkdoZvgwp" passwordLocation="url"
    passwordSource="file:///usr/local/passwords/projectXYZ/password"/>

    mrg
