I have only the one place for configuring c3p0. The only other .xml I have is web.xml, which doesn't mention c3p0. (There's also a log4j config.)
Maybe c3p0 has a default, but jetty should reinit with the same params it initted with, right? All I did for c3p0 was copy the jar into lib/ext/ and add the config I gave. <div>-------- Original message --------</div><div>From: Joakim Erdfelt <[email protected]> </div><div>Date:09/25/2015 2:54 PM (GMT-08:00) </div><div>To: JETTY user mailing list <[email protected]> </div><div>Subject: Re: [jetty-users] c3p0 driver switches postgres->mysql on context reload, 9.3.4-SNAPSHOT </div><div> </div>The c3p0 configuration seems to be coming from multiple locations. Are you also configuring it in your ${jetty.base}/webapps/${context}.xml ? Is it also being configured from Spring? or Hibernate? Or c3p0 properties file? Or c3p0 system properties?

It looks like on modifying a web page in ROOT that context reinitializes and this restarts c3p0 with mysql instead of my spec of postgres, and jetty has to be killed/restarted. Gory details follow. I switched from mysql to postgres, and things worked fine until I got around to removing a mysql-driver.jar I had from somewhere (I thought it had been superseded by mysql-connector-java-5.1.36-bin.jar). This seems to have uncovered a problem with jetty when a page in ROOT is modified and context is refreshed. On initialization I have c3p0 following my config: Sep 25, 2015 2:21:10 PM com.mchange.v2.c3p0.impl.AbstractPoolBackedDataSource getPoolManager INFO: Initializing c3p0 pool... com.mchange.v2.c3p0.ComboPooledDataSource [ acquireIncrement -> 3, acquireRetryAttempts -> 30, acquireRetryDelay -> 1000, autoCommitOnClose -> false, automaticTestTable -> null, breakAfterAcquireFailure -> false, checkoutTimeout -> 0, connectionCustomizerClassName -> null, connectionTesterClassName -> com.mchange.v2.c3p0.impl.DefaultConnectionTester, dataSourceName -> 1hge13a9c1rqmnbcm92m8|6356695f, debugUnreturnedConnectionStackTraces -> false, description -> null, driverClass -> org.postgresql.Driver, <====**** *** *** Now I edit one of my html pages and it is detected: 2015-09-25 14:23:47.767:INFO:oejsh.ContextHandler:Scanner-0: Stopped o.e.j.w.WebAppContext@15975490{/,null,UNAVAILABLE}{/ROOT} Servlets claim they initted ok: 14:23:48.011 [Scanner-0] INFO com.priot.servlet.GetNext - GetNext Init OK 14:23:48.012 [Scanner-0] INFO com.priot.servlet.GetSession - GetSession Init OK Back to normal it would seem: 2015-09-25 14:23:48.012:INFO:oejsh.ContextHandler:Scanner-0: Started o.e.j.w.WebAppContext@6c0002ea{/,file:///Users/priot/pr/jetty-base/webapps/ROOT/,AVAILABLE}{/ROOT} Now I reload the changed page on the browser: 14:29:17.110 [qtp553264065-14] INFO com.priot.servlet.GetSession - GetSession POST 0:0:0:0:0:0:0:1 | 0:0:0:0:0:0:0:1 | hour=14 | tzoff=420 | lang=en-US | platform=MacIntel | browser=Netscape | version=5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.93 Safari/537.36 | username=zzz Sep 25, 2015 2:29:17 PM com.mchange.v2.c3p0.DriverManagerDataSource ensureDriverLoaded WARNING: Could not load driverClass com.mysql.jdbc.Driver java.lang.ClassNotFoundException: com.mysql.jdbc.Driver at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at com.mchange.v2.c3p0.DriverManagerDataSource.ensureDriverLoaded(DriverManagerDataSource.java:100) at com.mchange.v2.c3p0.DriverManagerDataSource.getConnection(DriverManagerDataSource.java:132) at com.mchange.v2.c3p0.WrapperConnectionPoolDataSource.getPooledConnection(WrapperConnectionPoolDataSource.java:182) at com.mchange.v2.c3p0.WrapperConnectionPoolDataSource.getPooledConnection(WrapperConnectionPoolDataSource.java:171) at com.mchange.v2.c3p0.impl.C3P0PooledConnectionPool$1PooledConnectionResourcePoolManager.acquireResource(C3P0PooledConnectionPool.java:137) at com.mchange.v2.resourcepool.BasicResourcePool.doAcquire(BasicResourcePool.java:1014) at com.mchange.v2.resourcepool.BasicResourcePool.access$800(BasicResourcePool.java:32) at com.mchange.v2.resourcepool.BasicResourcePool$AcquireTask.run(BasicResourcePool.java:1810) at com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread.run(ThreadPoolAsynchronousRunner.java:547) And after some of that: Sep 25, 2015 2:29:17 PM com.mchange.v2.c3p0.impl.AbstractPoolBackedDataSource getPoolManager INFO: Initializing c3p0 pool... com.mchange.v2.c3p0.ComboPooledDataSource [ acquireIncrement -> 3, acquireRetryAttempts -> 30, acquireRetryDelay -> 1000, autoCommitOnClose -> false, automaticTestTable -> null, breakAfterAcquireFailure -> false, checkoutTimeout -> 0, connectionCustomizerClassName -> null, connectionTesterClassName -> com.mchange.v2.c3p0.impl.DefaultConnectionTester, dataSourceName -> 1hge13a9c1rqmnbcm92m8|48b30e5d, debugUnreturnedConnectionStackTraces -> false, description -> null, driverClass -> com.mysql.jdbc.Driver, <=== ** ** ** Why the sudden interest in mysql???
