我正在学习第一个cup教程，但是我在chapter 4的结尾处卡住了，有以下例外：
java.sql.SQLException:分配连接时出错。原因：无法分配连接，因为：DERBY SQL错误：错误代码：40000，SQL状态：XJ041、SQLERRMC：无法创建数据库“sun-appserv-samples”，请参阅下一个异常以了解详细信息。：：SQLSTATE：XBM 01：：SQL状态：新佳001
在“项目”选项卡中，我选择firstcup-war项目，右键单击并选择“运行”。
输出选项卡显示：

Deploying on GlassFish Server
    profile mode: false
    debug mode: false
    force redeploy: true
In-place deployment at /home/t/NetBeansProjects/firstcup-war/target/firstcup-war
GlassFish Server, deploy, null, false

"Java DB数据库进程“选项卡显示
