Essential report server error
Posted: 28 Mar 2014, 21:27
I have downloaded the essential project for evaluation, and I confess that I am unfamiliar with Tomcat. I am installing on a Windows 2K8 R2 VM in VMware Workstation. I am able to view the homepage of the essential viewer as well as click on the various buttons and links to catalogs. However, within the Protégé application, on the essential viewer tab, I am unable to publish the repository. My error is "No response from the Report Service at this URL."
Reading the other posts on this site I have done several things to troubleshoot. I have uninstalled and reinstalled both the essential application and the Tomcat server. I have examined the log files. I am getting a 500 error with both GET and POST requests to the reportService URL
The localhost log also records a NullPointerException error as seen below
28-Mar-2014 06:54:19.268 SEVERE [28] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [reportService] in context with path [/essential_viewer] threw exception
as far as I can tell, the problem is that the report server servlet has not properly deployed. Can you give me any guidance on how to overcome this?
