Java代码运行在Windows上，但不是在Linux上
我有这个代码，我试图在Windows上运行一些代码，这是运行良好，因为我得到所需的输出

Exception in thread "main" java.lang.NoClassDefFoundError: com/jacob/activeX/ActiveXComponent at ExpressionTransformerImpl.getDummyResultForFormul(ExpressionTransformerImpl.java:183) at ExpressionTransformerImpl.isValidFormula(ExpressionTransformerImpl.java:161) at ExpressionTransformerImpl.createExecutableForumalaFromString(ExpressionTransformerImpl.java:60) at ExpressionTransformerImpl.main(ExpressionTransformerImpl.java:221) Caused by: java.lang.ClassNotFoundException: com.jacob.activeX.ActiveXComponent at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358)
编译这个，我使用下面的命令
javac -cp jacob.jar ExpressionTransformerImpl.java
并运行这个，我使用这个命令
java ExpressionTransformerImpl
我该如何解决这个问题？
任何帮助将非常感激。
你不走运。 JACOB需要一个只适用于Windows的jacob.dll文件。
ActiveX在Linux上不可用，因为它（如jacob）需要Windows二进制文件。 我认为即使使用像Wine这样的模拟器也无济于事，因为在Wine上运行Excel不是最简单的。
也许最好的方法是切换到独立的平台来创buildXLS文件： https ： //poi.apache.org/
我没有提供一个例子，因为我确定有很多使用谷歌或stackoverflow被发现。
