[Pki-users] tomcat error

I'm unsure what exactly caused this but when i attempt to access my instance of dogtag tomcat is reporting the following errors; org.apache.jasper.JasperException: An exception occurred processing JSP page /index.jsp at line 172 169: } 170: 171: ServletContext tksContext = getServletContext().getContext("/tks"); 172: String tksName = tksContext.getServletContextName(); 173: String tksPath = tksContext.getContextPath(); 174: if (!"".equals(tksPath) && request.isSecure()) { 175: %> Is it possible to re-install the tomcat instance without losing my CA install? Or can anyone suggest another resolution. Cheers Rees
