我可以在jar文件之外运行我的程序,但我想部署它并将其作为jar运行。
此命令适用于运行.class文件:
java -classpath .;./libs/mail.jar;./libs/jcommon-1.0.16.jar;./libs/jfreechart-1.0.13.jar;./libs/jxl.jar;./libs/ojdbc5.jar gdsreports/ReportsDriver
这就是我打包jar文件的方式:
jar -cfvm GDSReports.jar GDSReports.mf gdsreports/* util/* libs/*
我的清单看起来像这样:
Manifest-Version: 1.0
Main-Class: gdsreports.ReportsDriver
Created-By: Me
这就是我运行jar的方式:
java -classpath .;./libs/mail.jar;./libs/jcommon-1.0.16.jar;./libs/jfreechart-1.0.13.jar;./libs/jxl.jar;./libs/ojdbc5.jar;./util;./gdsreports -jar GDSReports.jar
但是,运行我运行jar文件,它无法加载所有库。这是它吐出来的:
Error loading configuration file: config/reportConfig
Error loading configuration file: config/gdsIds
Exception in thread "main" java.lang.NoClassDefFoundError: jxl/write/WriteException
at util.ReportConfig.setupReports(ReportConfig.java:197)
at util.ReportConfig.setup(ReportConfig.java:65)
at gdsreports.ReportsDriver.main(ReportsDriver.java:36)

at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
... 3 more
这是预期的输出:
Error loading configuration file: config/reportConfig
Error loading configuration file: config/gdsIds

我做错了什么?
答案 0 :(得分:1)
使用-classpath
参数时,将忽略CLASSPATH
参数(以及-jar
环境变量)。
如果jar文件依赖于其他库,则有两种选择:
Class-Path
文件中的MANIFEST.MF
