怎样配置poolman连接池，运行环境windows 2000server,mysql,resin;测试时报错！在线等！！！

[Explorerwen]

我在配置poolman连接池的时候，poolman.jar,jdbc-mysql.jar放在CLASSPATH中，poolman.xml文件的路径，E:\poolman\lib也放在CLASSPATH中；其他的配置也是按poolman自带的文档进行配置的！可在测试时却报错！
运行环境windows 2000server,mysql,resin;
测试如下：
E;\poolman\samples>runSample.bat "select * from Introduce" "wen"
Exception in thread "main"java.lang.NoClassDefFoundError:org/apache/log4j/Layout
at com.codestudio.util.SQLManager.createPool(Unknown Source)
at com.codestudio.util.SQLManager.getPool(Unknown Source)
at com.codestudio.util.SQLManager.LocalPoolDeployer.startdataSources(Unknown Source)
.

at com.codestudio.util.SQLUtil.execute(Unknown Source)
at PoolManSample.doSQL(PoolManSample.java:51)
at PoolManSample.main(PoolManSample.java:305)
请问发生异常的原因？如何修改？？？还有"Unknown Source"是什么错？什么原因？？

可能是poolman.xml里的配置不正确，看看驱动、数据库名、用户等有没有错

I've never tried poolman.
but resin has its own connection pool, you can config datasource in resin.conf.
good luck!

org/apache/log4j/Layout

You need log4j.jar exists in classpath.
Get it from apache.

这个错误怎么解决啊？在那里可以找到“vfs"or"LogStream"
大家帮忙啊！！！

Add third-party JAR extensions to your CLASSPATH.
log4.jar, crimson.jar, jaxp.jar, jdbc2_0-stdext.jar must be available.

还要记得把mysql的jdbc放到classpath

I think it exists in resin.jar, the lib file of resin application server.

这个好像是resin提供的一个支持mysql的jdbc的包了的 你查查看
