Hi Don’t add multiple webapps to Solr’s Jetty. Install a separate Jetty on another port for your other apps. Solr using Jetty is an implementation detail which may suddenly disappear in a future release.
You will find that Jetty is very light weight and it is a much cleaner approach to run a separate one for your apps! -- Jan Høydahl, search solution architect Cominvent AS - www.cominvent.com > 9. mai 2016 kl. 08.00 skrev t...@sina.com: > > Hi, > At present I try to deploy multiple web applications to Solr Jetty.
