Jetty Server Classpath is determined by a combination of factors.
--lib=<path> can be used as a final means to add arbitrary entries to the Jetty Server classpath.Of special note, there are 2 structural modules defined to ease some of this for you.
ext module will enable the lib/ext/*.jar logic.
+
If this module is activated, then all jar files found in the lib/ext/ paths will be automatically added to the Jetty Server Classpath.resources module will add the resources/ directory the classpath.
+
If you have 3rd party libraries that lookup resources from the classpath, put your files in here.
+
Logging libraries often have classpath lookup of their configuration files (eg: log4j.properties, log4j.xml, logging.properties, and logback.xml), so this would be the ideal setup for this sort of configuration demand.Note
Both the
extandresourcesmodules declare relative paths that follow Jetty Base and Jetty Home path resolution rules.
The Jetty start.jar has the ability to resolve the classpath from the command line, modules and configuration, and to list the classpath entries it will use to start jetty.
The --list-classpath command line option is used as such.
(Demonstrated with the demo-base from the Jetty Distribution)
[demo-base]$ java -jar $JETTY_HOME/start.jar --list-classpath
Jetty Server Classpath:
-----------------------
Version Information on 42 entries in the classpath.
Note: order presented here is how they would appear on the classpath.
