我正在尝试在 opensuse 上使用 h2 数据库,但无法使其正常工作。我从官方网站下载了平台无关的包,然后尝试了几件事来运行它,但没有成功:
- 使 /h2/bin/h2.sh 可执行,然后执行控制台命令 ./h2.sh
- 使用命令 java -jar h2*.jar
- 使用 Play!Framework 命令 h2-browser
所有三个都返回相同的错误:

这是我的 java -version:
java version "1.7.0_21"
OpenJDK Runtime Environment (IcedTea 2.3.9) (suse-3.37.1-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)
我的 javac 版本:
javac 1.7.0_21
更多信息: 我请朋友尝试在 UnbuntuX 上运行它,使用 java -jar h2*.jar 程序,它工作(我们有相同的 java 版本,省略了 linux 发行版)。我请另一个朋友尝试在他的计算机上使用 Opensuse 运行它,它没有工作,与我的错误相同。
谢谢
编辑:根据需要,etc/hosts 文件的内容:
#
# hosts This file describes a number of hostname-to-address
# mappings for the TCP/IP subsystem. It is mostly
# used at boot time, when no name servers are running.
# On small systems, this file can be used instead of a
# "named" name server.
# Syntax:

# IP-Address Full-Qualified-Hostname Short-Hostname
