serialver [ options ] [ classnames ]

options

The command-line options. See Options.

classnames

The classes for which the serialVersionUID is to be returned.

The serialver command returns the serialVersionUID for one or more classes in a form suitable for copying into an evolving class. When called with no arguments, the serialver command prints a usage line.

-classpath path-files

Sets the search path for application classes and resources. Separate classes and resources with a colon (:).

-show

Displays a simple user interface. Enter the full class name and press either the Enter key or the Show button to display the serialVersionUID.

-Joption

Passes option to the Java Virtual Machine, where option is one of the options described on the reference page for the Java application launcher. For example, -J-Xms48m sets the startup memory to 48 MB. See java(1).

The serialver command loads and initializes the specified classes in its virtual machine, and by default, it does not set a security manager. If the serialver command is to be run with untrusted classes, then a security manager can be set with the following option:

-J-Djava.security.manager

When necessary, a security policy can be specified with the following option:

-J-Djava.security.policy=<policy file>
