13.8.2002 - [different files] : roc - changed all hardcoded occurrences of /docuserver/digitallibrary to work relative or take the path from the request URL. Introduced a variable baseURL to hold the URL path (up to digilib.jsp etc.). Now it should be possible to install digilib in other directories. - removed xerces.jar. It seems not necessary any more (JDK 1.3.1, Tomcat 4.0.4)
