Description of problem:

Tomcat 7's sessionsList.jsp does not work since it still has a dependency on an ha class (DeltaSession), which we don't provide in EWS.  We should ensure this is accounted for in EWS 3.  It throws an error like the following:

An error occurred at line: [18] in the generated java file: [/usr/share/tomcat7/work/Catalina/localhost/manager/org/apache/jsp/WEB_002dINF/jsp/sessionsList_jsp.java]
Only a type can be imported. org.apache.catalina.ha.session.DeltaSession resolves to a package

An error occurred at line: 109 in the jsp file: /WEB-INF/jsp/sessionsList.jsp
DeltaSession cannot be resolved to a type
106:        Session currentSession = (Session) iter.next();
107:        String currentSessionId = JspHelper.escapeXml(currentSession.getId());
108:        String type;
109:        if (currentSession instanceof DeltaSession) {
110:            if (((DeltaSession) currentSession).isPrimarySession()) {
111:                type = "Primary";
112:            } else {
