我们有一个 Solr 索引应用程序。它在 Lubuntu 10.10（这是我的本地 Linux 机器）上运行得很好。但我无法在主机 Debian 2.6.26-15lenny3（gcc 版本 4.1.3 20080704（预发布版）（Debian 4.1.2-25））中运行它。我认为配置没问题，因为 tomcat 管理员可以看到 solr（运行状态为“false”），而且它在 Lubuntu 上也能运行。在 catalina 日志文件中有一个错误：

同时，（默认）Jetty Solr（刚刚安装）开始工作。另外，也许有必要说一下，我在 Debian 上安装 Java 和 Tomcat 时遇到了一些困难。我不得不使用测试存储库来安装 tomcat6。
当我尝试从 shell 手动启动 solr 和 jetty 时

感谢您的帮助。
