运行selenium2出现NoClassDefFoundError

[MountLion]

下载了selenium2alpha4版本，是一个zip包，解开后是一些jar文件，因为需要在classpath设置这些文件，所以编写了一个cmd文件：
==================
set java_home=C:\Program Files\Java\jre6

set classpath=.;selenium-server-2.0a4.jar;ant-1.6.5.jar;bcprov-jdk15-135.jar;commons-codec-1.4.jar;commons-collections-3.2.1.jar;commons-httpclient-3.1.jar;commons-io-1.4.jar;commons-lang-2.4.jar;commons-logging-1.1.1.jar;cssparser-0.9.5.jar;google-collect-1.0.jar;hamcrest-all-1.1.jar;htmlunit-2.7.jar;htmlunit-core-js-2.7.jar;jmock-2.4.0.jar;jmock-junit3-2.4.0.jar;jna.jar;json-20080701.jar;junit-3.8.1.jar;mx4j-tools-3.0.1.jar;nekohtml-1.9.14.jar;sac-1.3.jar;serializer-2.7.1.jar;servlet-api-2.5-6.1.9.jar;xalan-2.7.1.jar;xercesImpl-2.9.1.jar;xml-apis-1.3.04.jar

"%java_home%\bin\java" -jar selenium-server-2.0a4.jar
==================
运行后报错:

可是commons-logging-1.1.1.jar中明明有org.apache.commons.logging.LogFactory这个类（接口）啊！

"%java_home%\bin\java" -jar selenium-server-2.0a4.jar
这个是做什么的？

commons-logging-1.1.1.jar 和selenium-server-2.0a4.jar 什么关系?

[crazylaa]

怀疑是classpath不对，commons-logging-1.1.1.jar并没有被找到
set classpath=这里，每个jar都写全路径吧。要不就

set MCP=D:/lib

set classpath=％MCP％×××.jar;％MCP％×××.jar

不懂??????????????

[bunrise]

貌似JAVA_HOME设置错了，应该是JDK哪个目录，不是JRE。这个你看看

[MountLion]

改用了jdk，还是报同样的错误。
classpath每个jar增加了绝对路径，还是一样。
郁闷啊

下载了selenium2-standalone，可以正常运行了。
