You can use serialver to inspect the current value of the 'private static final long serialVersionUID'. You do not need to have this set unless you have modified a class and wish to remain serial compatiblity with an older version. For example if you change a method name, but the serial contents are the same you may wish to provide an explicit serialVersionUID to retain backwards compatiblity, else a new serialVersionUID will be created.
If you want the exact details on how this long is created, then I am not sure. I think it is done by a secure hash of the public interface (or public methods), but that is just a guess. This probably provides more information: http://java.sun.com/j2se/1.4/docs/guide/serializatiohttp://java.sun.com/j2se/1.4/docs/guide/serialization/spec/class.doc6.html#4100n/spec/class.doc6.html#4100 * * * If this completly not what you were looking for then please ignore =) --jason On Mon, 19 Nov 2001, Bill Burke wrote: > I only read about this, but look at the Proxies. serialver outputs the > serialVersionUID then you cut and paste it into a static variable in the > class file?
