Hide password in java ant task

Hi All,

I am using ant java task to execute a class file and passing some argument
to it. one of the argument to this java class is the database password.

When the java task is getting executed, the entire command along with the
password is displayed in the process (ps -ef).

Is  there any way to direct the java task to hide the password .

eg:
        <target name="gentest" >
        <java classname="Test2" fork="yes" failonerror="true">
            <arg value="${DBuser}/${DBpsswd}"/>
            <classpath>
                <pathelement path="/u01/user2/patch/testjavac"/>
            </classpath>

        </java>
        </target>


Note: Normally for other perl applications,  we are passing the password as
a piped argument. Is there any similar feature in ant.

eg: { echo "password"; } | perl test.pl

Thanks,
Muralidhar

Thanks David.

With "inputsstring" property, the passwords were not visible in the output
of ps commands.

Thanks,

RE: Hide password in java ant task

Posted by David Parks <da...@yahoo.com>.

Your java class is going to need to be able to input the password on STDIN I
believe.

Assuming you control 'Test2' (in your example) enough to make that happen,
then take a look at the input and inputstring propery of the java task, they
allow you to pass data in via STDIN. The best solution is to combine that
with the <input ...> task to prompt the user for the password at the time
you run ant.

Since I haven't used the java task I'll give you a heads up that my recent
use of inputstring in the exec class required that I compile the most recent
nightly build of 1.8.3 (inputstring wasn't implemented on the exec task
prior to a few weeks back), though hopefully in your case inputstring is
working as advertised in the docs for the java task.
