我在尝试使用 nohup 运行我的 java 代码时遇到问题：

[root@ /]# nohup opt/jdk1.6.0_22/bin/java -cp "lib/hibernate/*:lib/tuscany-sca-1.6/lib/*:lib/tuscany-sca-1.6/modules/*:./*" com.lab.launch.Launcher &

[1] 23148

nohup.out 的内容：

感谢您的帮助

【问题讨论】：

我们通常使用nohup $javastuff > $LOGFILE &。试试看。

标签： java linux daemon nohup

【解决方案1】：

Exception in thread "main" java.io.IOException: Bad file descriptor
    at java.io.FileInputStream.readBytes(Native Method)
    at java.io.FileInputStream.read(FileInputStream.java:199)
    at java.io.BufferedInputStream.fill(BufferedInputStream.java:218)
    at java.io.BufferedInputStream.read(BufferedInputStream.java:237)
    at com.xavier.launch.Launcher.main(Launcher.java:24)

您的应用程序（或其参数）中似乎存在错误，我不确定它与nohup 无关。它试图读取的文件是什么？
