class path问题

[fuyou001]

这是在myeclipse 项目上的classpath

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" path="src"/>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
	<classpathentry kind="lib" path="lib/commons-logging-adapters-1.1.1.jar"/>
	<classpathentry kind="lib" path="lib/log4j-1.2.15.jar"/>
	<classpathentry kind="lib" path="lib/commons-dbcp-1.2.2.jar"/>
	<classpathentry kind="lib" path="lib/commons-pool-1.4.jar"/>
	<classpathentry kind="lib" path="lib/classes12.jar"/>
	<classpathentry kind="lib" path="lib/apache-mime4j-0.6.jar"/>
	<classpathentry kind="lib" path="lib/commons-codec-1.3.jar"/>
	<classpathentry kind="lib" path="lib/commons-logging-1.1.1.jar"/>
	<classpathentry kind="lib" path="lib/httpclient-4.0.jar" sourcepath="F:/workspace/net/source/httpcomponents-client-4.0-src.zip"/>
	<classpathentry kind="lib" path="lib/httpcore-4.0.1.jar" sourcepath="F:/workspace/net/source/httpcomponents-core-4.0.1-src.zip"/>
	<classpathentry kind="lib" path="lib/httpmime-4.0.jar"/>
	<classpathentry kind="lib" path="lib/commons-lang-2.4.jar"/>
	<classpathentry kind="lib" path="lib/htmlparser.jar"/>
	<classpathentry kind="lib" path="lib/filterbuilder.jar"/>
	<classpathentry kind="lib" path="lib/htmllexer.jar"/>
	<classpathentry kind="lib" path="lib/sitecapturer.jar"/>
	<classpathentry kind="lib" path="lib/thumbelina.jar"/>
	<classpathentry kind="output" path="bin"/>
</classpath>

下面是我打包出来 jar
用bat文件设置classpath
set classpath=%CLASSPATH%;.;F:\lib\lib\commons-logging-adapters-1.1.1.jar;F:\log4j-1.2.15.jar;F:\lib\commons-dbcp-1.2.2.jar;F:\lib\commons-pool-1.4.jar;F:\lib\classes12.jar;F:\lib\apache-mime4j-0.6.jar;F:\lib\commons-codec-1.3.jar;F:\lib\commons-logging-1.1.1.jar;F:\lib\httpclient-4.0.jar;F:\lib\httpcore-4.0.1.jar;F:\lib\httpmime-4.0.jar;F:\lib\commons-lang-2.4.jar;F:\lib\htmlparser.jar;F:\lib\filterbuilder.jar;F:\lib\htmllexer.jar;F:\lib\sitecapturer.jar;F:\lib\thumbelina.jar;
cd F:\Program Files\java1.6\bin
java -jar f:/spider.jar

两个classpath 一样，但为什么会报

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commo
gging/LogFactory

LogFactory是在commons-logging-1.1.1.jar里，但我在classpath里设置了
怎么还报这个错

F:\lib\lib\commons-logging-adapters-1.1.1.jar;F:\log4j-1.2.15.jar;

一个多了层lib目录一个少了层lib目录

恩

set classpath =.;
F:\lib\commons-logging-adapters-1.1.1.jar;
F:\lib\log4j-1.2.15.jar;
F:\lib\commons-dbcp-1.2.2.jar;
F:\lib\commons-pool-1.4.jar;
F:\lib\classes12.jar;

F:\lib\htmlparser.jar;
F:\lib\filterbuilder.jar;
F:\lib\htmllexer.jar;
F:\lib\sitecapturer.jar;
F:\lib\thumbelina.jar;
F:\lib\commons-logging-1.1.1.jar;

cd  F:\Program Files\java1.6\bin
java  -jar f:/spider.jar
pause;

上面是修改过来的，最后一个就是，但问题依旧

spider.jar中meta-inf文件的classpath

楼上解决这种问题不低于10次了

我到后来也没加上，好像换了下jar包顺序就好了，真郁闷

[借我那把枪吧]

顶二楼的，按照他说的没错
