Serialization and Clustering

[Timothy Sam]

Hi, I'd like to ask if implementing the Serializable interface is manadatory in Tomcat if I want to do clustering in the future? Then, maybe I should also mark some of my members transient? I always get this warning message in Eclipse

SeverityDescriptionResourceIn FolderLocationCreation TimeId
1The serializable class SearchResultsForm does not declare a static final serialVersionUID field of type longSearchResultsForm.javaAssetManagementSystem/src/beansline 10June 23, 2006 1:32:13 PM5313

and it kind of bothers me... Any ideas?
