--- Comment #4 from Christopher Schultz <ch...@christopherschultz.net> --- ... and how do you obtain connections and then use them? The DataSourceFactory.getConnection method does not need to be synchronized. Read further and you'll find that it is indeed threadsafe. When you say "on jboss not get the problem", do you mean that when you use JBoss and tomcat-pool you don't see this problem? Or are you using JBoss's contained-managed DataSource. Is there a particular reason you feel like you must choose between tomcat-pool and c3p0? What about Tomcat's default pool... the one based upon dbcp2? -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
