JDBC连接SQL server2000错误！已经打了SP3,SP4补丁，JDK1.4.2,TOCAT 5.0.27,用JBUILDER编译

Question

说明：环境变量为：classpath=C:\Borland\JBuilder2005\jdk1.4\lib;.;C:\Borland\JBuilder2005\thirdparty\jakarta-tomcat-5.0.27\common\lib\servlet-api;C:\Borland\JBuilder2005\thirdparty\jakarta-tomcat-5.0.27\common\lib\jsp-api;.;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msbase.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\mssqlserver.jar;C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\msutil.jarpath=.;C:\Borland\JBuilder2005\jdk1.4\bin;C:\Borland\JBuilder2005\thirdparty\jakarta-tomcat-5.0.27\bin
也把那三个JAR文件放到了TOMCAT文件夹了
但显示错误如下：

谢谢各位，我搞定了！原来是补丁没安装好！不过我试着换TOMCAT5.5+JDK1.6却出现这个问题：C:\Borland\JBuilder2005\jdk1.4\bin\javaw -classpath "E:\Tomcat 5.5\bin\bootstrap.jar;C:\Borland\JBuilder2005\jdk1.4\lib\tools.jar"  "-Dcatalina.home=E:/Tomcat 5.5"  org.apache.catalina.startup.Bootstrap -config E:\wangye\newpro\Tomcat\conf\server8083.xml start 
This release of Apache Tomcat was packaged to run on J2SE 5.0 
or later. It can be run on earlier JVMs by downloading and 
installing a compatibility package from the Apache Tomcat 
binary download page.环境变量也重新配置了，也不行。
