I was working with Eva-Maria.Gerstner@senckenberg.de on an installation of Metacat 2.8.1 and we could not get Metacat to fully initialize after configuring it in the admin screens. On restart, we would get as far as the 

metacat 20170324-18:24:19: [DEBUG]: XMLService.doRefresh - refreshing the schema service. [edu.ucsb.nceas.metacat.service.XMLSchemaService]
</code>

and then it would never get beyond that because of an unexpected exception in that routine:

24-Mar-2017 18:15:38.600 SCHWERWIEGEND [localhost-startStop-1] org.apache.catalina.core.StandardContext.loadOnStartup Servlet [metacat] in web application [/metacat] threw load() exception

Just tried Metacat 2.8.5 on tomcat 8.0. It works fine.

I ran the junit test against tomcat and there is no failure.

However, we need to run the integration replication (both metacat and dataone ) tests as well.

Some production Metacat server such as CERN is running on Tomcat 8.0. It works well. I also ran the junit test against tomcat 8 and didn't see any issue.

Great. @taojing2002, can you update the installation documents to reflect this please?

taojing2002 commented 5 years ago

I updated the documents.
