tomcat4中怎样设置classpath？

楼主homey123（icemat）2002-03-13 12:28:26 在 Java / J2SE / 基础类 提问

机器的classpath已经设置好，用tomcat3.2可以正常发布，但改成tomcat4后提示找不到.class

你是否在classpath中加入了   JAVA_HOME/lib/tools.jarTop

2 楼free_free（free_free）回复于 2002-03-13 13:15:23 得分 10

CLASSPATH=D:\jdk\lib\tools.jar;D:\jdk\lib\dt.jar;D:\tomcat4\common\lib\servlet.jarTop

加上了也不好用，还是那样！  
  Undefined   variable,   class,   or   package   name:   com   out.print(com.det.Util.getCurrentDate("YYYY-MM-DD"));    
  com.det.Util是我自己写的类，我把写好的class都放在E:\classpath下了，然后在CLASSPATH中加上E:\classpath，但运行jsp页面却提示找不到class，  
  我用tomcat3.2发布就可以，但4.0.3版就出问题!Top

终于找到问题了  
  在tomcat/bin/setclasspath.bat文件中  
  自代的设置classpath行为  
  set   CLASSPATH=%JAVA_HOME%\lib\tools.jar  
  后面加上环境变量中的%CLASSPATH%就可以了！  
  set   CLASSPATH=%JAVA_HOME%\lib\tools.jar;%CLASSPATH%Top
