Connection Pooling using Jetty, in Oracle

You have 3 ways to do it:

1. If you are using maven or gradle in your project simply add commons-pool dependency to your pom.xml or build.gradle file (recommended way)
2. If you are not using one of the mentioned tools place correct jar in the WEB-INF/lib directory
3. The last one is to place jar in ${jettyHome}/lib directory

Make sure that you are using correct version of the commons-pool for your current commons-dbcp implementation

you don't you just use tomcat instead. find it here http://tomcat.apache.org/ :)Note that jetty is only well to be used when you need to make local app development easier.https://tomcat.apache.org/tomcat-7.0-doc/jdbc-pool.htmlI suggest you start reading up the basics for tomcat and as you begin to gain a basic understanding of how things work, you should start implementing Connection Pooling :) Hope this helps.

For Jetty 10.x you could resolve it in the following way,

1. Enable ext module -> java -jar start.jar --add-modules=ext
2. In $JETTY_BASE/start.d/ext.ini will get created after execution of 1)
3. Place your oralce jdbc jar file in location $JETTY_HOME/lib/ext/
4. Again start your application -> java -jar start.jar
