Jodi, the server.xml is in the /tomcat-directory/conf/. And you have to
modify one class, in concrete RequestInfo.java making this class
serializable adding the following code in RequestInfo.java:
java class RequestInfo implements java.io.Serializable{....
After this you have to recompile the DSpace code, stop Tomcat, copy the
war in /tomcat-directory/webapps/ and start Tomcat.
cheers,
Jesús
