我想运行 JasperReport，所以根据它的文档，我尝试在我的 Windows 7 上运行 HSqlDB 数据库，如下所示：-

C:\jasperreports-4.7.0\demo\hsqldb>ant

但它会引发以下问题：-

Buildfile: C:\jasperreports-4.7.0\demo\hsqldb\build.xml

java.net.BindException: Address already in use: JVM_Bind表明其他一些进程已经在使用您希望 hsqldb 服务器侦听的端口。netstat -an应该给您一个网络连接列表，您可以查看该列表以查看该端口是否确实在使用；netstat -abn还将为您提供与每个连接关联的进程，但运行此命令需要提升。
