这不写的很清楚么

[真的很小奚]

JAVA_HOME 错了

[jjoohhnn13]

检查下JDK环境的配置

[longer84]

JAVA_HOME
检查下JDK环境的配置
绝对没有问题!

[longer84]

CLASS_PATH=.;C:\j2sdk1.4.2_13\lib
JAVA_HOME=C:\j2sdk1.4.2_13
PATH=.;C:\j2sdk1.4.2_13\bin;C:\Program Files\PC Connectivity Solution\;C:\oracle\ora92\bin;C:\Program Files\Oracle\jre\1.3.1\bin;C:\Program Files\Oracle\jre\1.1.8\bin;C:\Program Files\IDM Computer Solutions\UltraEdit-32

配置是这样的!请指教!

[真的很小奚]

你的tomcat是什么版本的 5.5以上不支持JDK1.4的，你的TOMCAT要是的5.5以上话安装JDK1.5吧
网上还有JDK1.4与TOMCAT5.5.*兼容的方法你在找吧

[longer84]

我的tomcat版本是:Apache Tomcat/5.0.28!怎么就这么难呢!

[真的很小奚]

伟大的LZ你的CLASSPATH有问题
.;E:\Program Files\Java\jdk1.5.0_03\lib\dt.jar;E:\Program Files\Java\jdk1.5.0_03\lib\tools.jar;E:\Program Files\Java\jdk1.5.0_03\jre\lib\rt.jar;E:\Program Files\Java\jdk1.5.0_03\jre\lib\charsets.jar;E:\Program Files\Java\jdk1.5.0_03\jre\lib\jaws.jar;G:\Tomcat 5.0\common\lib\servlet-api.jar;F:\eclipse soft\struts-1.2.9-bin\lib\struts.jar给你参照下我的CLASSPATH看你都少什么包。

[真的很小奚]

CLASSPATH不是只加目录就可以的。

[longer84]

还是不对！哎

[Kevinyao93]

CLASSPATH设置错了

[longer84]

class_path=.;C:\j2sdk1.4.2_13\lib\tools.jar;C:\j2sdk1.4.2_13\lib\dt.jar;C:\j2sdk1.4.2_13\jre\lib\rt.jar;C:\Tomcat 5.0\common\lib\servlet-api.jar;C:\Tomcat 5.0\common\lib\jsp-api.jar

[真的很小奚]

I 服了 YOU
是classpath 不是class_path
我要去找快豆腐了

[longer84]

哎！还是不对！

[真的很小奚]

建议LZ找本入门教材认真学习

[newer0]

貌似程序编译没通过？？
先保证程序没问题再来试吧。

[zhuyl_wind]

Unable to find a javac compiler;

[longer84]

已解决！

[longer84]

呵呵！没一个说中要害的！

[真的很小奚]

你所说要害是什么贴出来看看。你别说class_path 这样写是对的。那我又学到知识了感谢LZ。
