[标题]:[原]命令行运行class文件出现NoClassDefFoundError
[时间]:2012-02-14
[摘要]:Java命令运行程序时出现java.lang.NoClassDefFoundError: org/apache/http/HttpEntity。
[关键字]: Java、package、Jar、运行、error、class-path、库、HttpClient
[文章编号]:暂无
[环境]: JDK 7.0
[作者]: Wintys (wintys@gmail.com)
[错误]:
运行命令行:
java NetLogin -cp .;commons-codec-1.4.jar;commons-logging-1.1.1.jar;httpclient-4.1.3.jar;httpclient-cache-4.1.3.jar;httpcore-4.1.4.jar;httpmime-4.1.3.jar
出现如下错误:

[原因&解决]:
被运行的程序编译正常通过,运行却出现了NoClassDefFoundError,不知道是哪里出错了。找了半天,发现编译程序的命令行有问题,-cp参数应放到类名前面来:
java -cp .;commons-codec-1.4.jar;commons-logging-1.1.1.jar;httpclient-4.1.3.jar;httpclient-cache-4.1.3.jar;httpcore-4.1.4.jar;httpmime-4.1.3.jar NetLogin
