Linux 下后台启动Weblogic

正常情况下，使用telnet或SSH登陆linux后，使用./startWeblogic.sh在用户推出登陆后，weblogic也会停掉，这是因为wls进程依赖于telnet进程，解决方法有二： 1：切换到csh,键入命令 nohup ./startWeblogic.sh & 2: 切换到csh, ./startWeblogic.sh 启动后ctrl+z, 输入bg,进入后台模式 修改startWeblogic.sh 添加 JAVA_OPTIONS=-Djava.awt.headless=true可以是wls在linux上输出图片 java.sun.com/developer/technicalArticles/J2SE/Desktop/headless/ 原因如下 java 代码 The Sun AWT classes on Unix and Linux have a dependence on the X Window System: when you use the classes, they expect to load X client libraries and be able to talk to an X display server. This makes sense if your client has a GUI... unfortunately, it's required even if your client uses AWT but does not have a GUI. For example, you need access to an X server to use the java.awt.BufferedImage class. Access to an X display server means a few things: * An X display server is running somewhere. * The environment in which you run Java includes an environment variable DISPLAY identifying how to reach the server. * There are no security settings in the server to prevent your client from opening a connection. In general, if you're running your program from a terminal within the X Window System, all these things are true and the program just works. If you can run other X applications, like xterm or xclock, you should be able to run your Java AWT application. In non-graphical environments, such as a servlet engine, your program may not know how to find or connect to an X display server. A common solution here is to run a special non-display version of the X display server, Xvfb, and set DISPLAY to point to it. New information forJDK1.4: JDK1.4 evidently includes a new property that will allow the AWT to run in a headless (without a display) environment. This setting is supposed to solve the problem: java.awt.headless=true
