Thanks Uwe for clarification, But I think if we go with Jboss EAP instead of AS, then there are lot of things improved by redhat and don’t seems any issue with garbage collection as well.
Anyway nice explanation ☺ Thanks!

The installation of jetty shipped with Solr is optimized for the typical usage pattern of Solr. Webapp containers like JBoss often have additional monitoring modules that may have an impact on the performance (I know that Jboss often has crazy plugins in the JVM for that, which have a large impact on garbage collection). Sometimes the web app container ships with malfunctioning Java versions, so take care. Also some containers use incorrect charsets, so the UTF-8 decoding of %-encoded query parameters is broken. We have a workaround for that in later Solr versions (4.1+), but in general all this is not tested with foreign servlet containers, so we cannot give any support.

Currently, we are using Jboss AS in Production and don’t seems any issue till now since last 2-3 months. Thanks!

See Solr like a database server (MySQL or Postgres). Do you install MySQL inside a servlet container? - no it runs as a separate service in a separate process! Jetty has nothing to do with "playing around". Jetty is just the web connector of Solr and is the officially supported HTTP interface. Future versions of Solr may replace jetty by e.g. the netty library for high performance select-based I/O. Your custom application talks to Solr using the HTTP protocol, but that does not mean that Solr must run in your webapp container. Solr runs (like a MySQL database server) ideally as a separate JVM instance. That's the recommended installation. > Question 2 related to the point - "*Future versions of Solr may no > longer ship > with a WAR file because it causes too many problems, because Solr does > not > work well with other webapps in the same JVM"* > * > * > how can we use solr with any app say my own web app (typically, a > spring > mvc or any EE app) if it is not shipped as war?
