Hello List,
I am currently using an ontology plugin within the Apache Nutch project. As
part of its working the plugin uses Jena to enhance search results. When
attempting to use the plugin I expeirenced the above Status 500 problem. I
attach the exception which was caught within one of the JSP files used within
the plugin.
exception
org.apache.jasper.JasperException: An exception occurred processing JSP page
/./refine-query-init.jsp at line 34
31: try {
32: Configuration nutchConf = NutchConfiguration.get(application);
33: String urls = nutchConf.get("extension.ontology.urls");
34: ontology = new
org.apache.nutch.ontology.OntologyFactory(nutchConf).getOntology();
35: if (urls==null || urls.trim().equals("")) {
36: // ignored siliently
37: } else {
Stacktrace:
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:510)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:401)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)
Having undertaken some reading on this plugin, I understand that this problem
might stem from Tomcat
and Jena using conflicting versions of the same Xerces library. My question is
what version of the Xerces library
does Jena currently use?
Hopefully if I can update my Xerces verson within Tomcat I can resolve this
issue.
Thank you
Lewis
