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
