埋め込みJettyでWebアプリケーション（WAR）を実行

Question

私はJettyを介して実行されているJavaの戦いを持っています。これは、複数のWindows 7コンピュータで長年働いています。しかし、Windows 7の新しいコンピュータにインストールしたときにエラーが発生し、そのエラーを理解できません。私は、エラーの時点までのログアップの下に掲載しています：私の他のWindows 7コンピュータでは

Answer 1

は、これが発生したときに桟橋の別のインスタンスかJettyサーバーが実行しようとしているのと同じポートで別のプロセスが実行されています。 Jettyはデフォルトのポート8080で動作します。そのため、別のJettyインスタンスまたはポート8080（または設定したポート）を占有しているサーバーでTomcatサーバーを実行している可能性があります。

あなたはこの行を変更してjetty.portをjetty.xmlファイルを変更し、更新することができます。

<Set name="port"><SystemProperty name="jetty.port" default="80"/></Set> 

しかし、それを行う前に、私は現在実行中の桟橋やTomcatなどのtaskmgr中のプロセスをチェックします。実行中のプロセスと使用しているポートについては、netstat -a -bを確認することもできます。
