-------------------------------------------------------------------------------- 大家好！ 我想请问一下 我的程序和数据库都没问题的情况下 编译时总出现java.lang.NullPointerException 是怎么回事 我电脑的操作系统home版的xp sp2的 数据库是SQL SERVER 2000的 是不是不能和数据库连接 也许是xp自带防火墙的问题 请问如何解决 以下是在jbuilder2005下编译时的错误提示： C:\Borland\JBuilder2005\jdk1.4\bin\javaw -classpath "C:\Borland\JBuilder2005\thirdparty\jakarta-tomcat-5.0.27\bin\bootstrap.jar;C:\Borland\JBuilder2005\jdk1.4\lib\tools.jar" "-Dcatalina.home=C:/Borland/JBuilder2005/thirdparty/jakarta-tomcat-5.0.27"
