Does JBOSS serialize all Collections as an ArrayList of some sort?
I have an EntityBean which has a Finder method which is declared as
returning a Colleciton. The actual bean implementation builds a LinkedList
of PrimaryKey objects which is returned for the ejbFindBy... call.
I have a Java servlet, running in the embedded Tomcat container which tries
to receive the Collection and cast it to a LinkedList. When the code runs
I get the following stack trace when this line of code runs.
LinkedList keys = (LinkedList)home.findByKeyword("PREPARE");
java.lang.ClassCastException: java.util.ArrayList

Any ideas?
