Java.net.ConnectException: connection refused

Aus Howtos und Gedankenstuetzen

Der jdbc-Mysql-Driver hat offensichtliche Probleme:

STACKTRACE:

java.net.SocketException: java.net.ConnectException: Connection refused
at com.mysql.jdbc.StandardSocketFactory.connect(StandardSocketFactory.java:151)
at com.mysql.jdbc.MysqlIO.<init>(MysqlIO.java:280)

at java.sql.DriverManager.getConnection(DriverManager.java:171)

Das Problem scheint unter Suse wohl ipv6 zu sein:

Ein auskommentieren folgender Zeile in der /etc/hosts behebt das Problem:

#::1 localhost ipv6-localhost ipv6-loopback
