(ABAP+Java Engine) Password change in SU01 be in sync with Java?

Hi,

In ABAP+Java engine,if I change the password of the "J2EE_admin" user at ABAP level in SU01,will it be changed at JAVA engine also?If I login with the user "J2EE_Admin" in Visual Administrator, will the changed password works?

If I change the password at UME will it be synchronised with the password in Visual admin or in SU01?
