The trouble with sending me email personally is not so much being annoying; as
not sharing your question with the user list. Sharing questions is one of the
*minimal* contributions you can make to an open source project; and open source
projects only thrive (and are there for you to build your work on when everyone
contributes something).
A quick answer is to copy the data into memory:
DataUtilities.collection( collection ).toArray();
Cheers,
Jody

hello it's me again,
i know it might be annoying to respond to each of the geotool users who writes
to you directly, but this is among my few last mails directly in your mailbox
i'd really appreciate an effort from you to respond this email. i need help on
how i could get an array of object of each feature in the featurecollection. i
have tried the FeatureCollection.getArray() method but i have this runtime
Exception:
java.lang.UnsupportedOperationException
at
org.geotools.data.store.ContentFeatureCollection.toArray(ContentFeatureCollection.java:379)

Subject: FeatureCollection serialisation
I am taking your email to the geotools user list; in a public forum you are
likely to get your question answered more promptly.
The quick solution is to go through the features; and ask each for its array of
objects; and serialise those. You can use the data utilities class to convert
the feature type information into a String (so you can create the features on
the other end to hold the result).
The more "correct" solution is to make use of a spatial format such as GeoJSON
or GML; there are some examples in the user guide.
In General GeoTools just provides the spatial stuff; leaving things like
communication up to your application.

hello,
yesterday i have sent you a mail describing that i was trying to move
org.geotools.data.DataStore through the java.rmi communication, but i have
figured out that no one of org.geotools interfaces implements the
java.io.Serialize interface; now i am wondering if maybe you could flash me
with some ideas and code examples if possible.
my name is Robert, i am a Rwandan student in Algeria, i am to develop GIS as
final project for my studies. i hope to find some help from you.

hello sir,
I'm a user of geotools and today i found out that rmi communication was not
possible. i'm to develop GIS with PostGIS as database and a geotools client,
communicating via java rmi. but i am having errors like this:
org.geotools.data.store.ContentFeatureCollection
at sun.rmi.server.UnicastRef.invoke(UnicastRef.java:173),
i thing dataStore and featureCollection interfaces are not extending
serialisable, i saw you are soo experimented in this project that's why i
choosed to write directly to you. thanks again for your comprehension. i'll be
a pleasure to hear from you.
