Question

我在Web应用程序（tomcat7）中有这个代码：

public InitBean() throws UnknownHostException, Exception {
    NetworkServerControl server = new NetworkServerControl(
            InetAddress.getByName("localhost"), 1527);
    server.start(new PrintWriter(System.err));

    String driver = "org.apache.derby.jdbc.ClientDriver";
    Class.forName(driver).newInstance();
    Connection conn = DriverManager.getConnection("jdbc:derby://localhost:1527/ctc;create=true");

}

目的是创建一个可以从webapp内部和外部访问的Derby数据库。这是一个涉及数据库ETL工具的不常见的用例。

我收到此错误：

这是在Windows 7,64位，Java 8和Tomcat 7上。

可能是什么问题？

更新

完全相同的代码在独立应用程序（J2SE / JUnit）中工作正常，但在Tomcat / Springframework下失败。

在webapp中运行时，Derby无法创建数据库？
