java.io.NotSerializableException: org.apache.slide.lock.NodeLock

["Pill, Juergen" <Ju...@softwareag.com>]

Hello,


As a first approach for persistency, we serialize all the data from the
various stores into a file. Trying to lock a resource open with Word 2000
(lock command) returns following exception: Can we make the class
org.apache.slide.lock.NodeLock  implements Serialisable?
