Oh, so arrays are marshalled automatically? Didn't know that :)

But you may be right in that it has trouble marshalling one item rather
than the array...

If only the error message werent so notoriously underspecified :)=20
You dont happen to know how to get tomcat to give some more information
when it fails?

I've been dry-reading most of the related sync4j source and xml files
now, and I'm "pretty sure" that sync4j is innocent, it's just that
particular webservice export thing that is failing (note that everything
else works fine, like adding devices, or adding/searching users, and so
on)

btw if the file says
'languageSpecificType=3D"java:sync4j.framework.server.Sync4jDevice"', does
that mean it will scan WEB-INF/classes for that class file ? or will it
scan the .jar files in WEB-INF/lib ? or both ?=20
(I'm asking because I have only sync4j/transport/http/server in classes,
nothing much else - the remainder is within file
WEB-INF/lib/sync4j-*.jar)
