高分求救。言出必行！

我把tomact配置好了以后例子可以运行但是我自己编的程序无法运行。求救高手！！！
我的用户变量设置为：
classpath:e:PROGRA~1Borlandvbrokerlibvbcpp.jar;d:jdk1.4libtools.jar;d:jdk1.4libdt.jar;D:Program FilesApache Tomcat 4.0libservlet.jar;D:Program FilesApache Tomcat 4.0webappsexamplesWEB-INFclasses

path:d:jdk1.4bin;d:jdk1.4

我的系统变量为：
classpath:d:jdk1.4libtools.jar;d:jdk1.4libdt.jar;D:Program FilesApache Tomcat 4.0libservlet.jar;D:Program FilesApache Tomcat 4.0webappsexamplesWEB-INFclasses

path:e:PROGRA~1BorlandDelphi5ProjectsBpl;e:PROGRA~1BorlandvbrokerjreBin;e:PROGRA~1BorlandvbrokerBin;e:PROGRA~1BorlandDelphi5Bin;%SystemRoot%system32;%SystemRoot%;%SystemRoot%System32Wbem;d:jdk1.4bin;d:jdk1.4;D:Program FilesMicrosoft SQL Server80ToolsBINN;d:jdk1.4bin;d:jdk1.4

我的jdk1.4装到d:,tomact装到d:/progarm filesapache tomact 4.0

已经用odbc建立了一个guestbook的系统数据源。
我把书上的例子（index.html,index.jsp,sql.java）拷到exmaples目录的jsp文件夹下，把sql.java拷到
examplesWEB-INFclasses下，运行后。index.html出现但我一按提交按钮，就出现以下状况：

好象是说class无法编译。

高手求就。我的头都快大了。
