---------------------------------------------------------------- BEFORE YOU POST, search the faq at <http://java.apache.org/faq/> WHEN YOU POST, include all relevant version numbers, log files, and configuration files. Don't make us guess your problem!!! ---------------------------------------------------------------- Hi again, Thanks for the reply.. I'm not sure that's correct though. I'm not an expert on serialization, but in section 10.7 of the Java Language Specification: http://java.sun.com/docs/books/jls/second_edition/html/arrays.doc.html it specifically says: Every array implements the interfaces Cloneable and java.io.Serializable Also, this code actually runs fine when run in a standalone java program or through servletrunner. The problem only occurs when loading the servlet through apache, and in fact only occurs when loading the class (actually trying to execute a line of code which casts an array to Serializable works fine as well) - is this perhaps a bug? If it is, can anyone think of a workaround? -Rich sven wrote: > > ---------------------------------------------------------------- > BEFORE YOU POST, search the faq at <http://java.apache.org/faq/> > WHEN YOU POST, include all relevant version numbers, log files, > and configuration files.
