关于debug时遇到的问题--救救我这个绝望的菜鸟!!给100分啊

[zft720]

我的jbuilder x装在D:\jbuilderx目录下,安装完成后,当我要debug程序时就出现以下错误信息
-- Cannot start Java debug process VM --
com.sun.jdi.connect.VMStartException: VM initialization failed for: D:\jbuilderx\jdk1.4\bin\javaw -classpath "D:\jbuilderx\samples\Welcome\classes;D:\jbuilderx\jdk1.4\demo\jfc\Java2D\Java2Demo.jar;D:\jbuilderx\jdk1.4\demo\plugin\jfc\Java2D\Java2Demo.jar;D:\jbuilderx\jdk1.4\jre\javaws\javaws.jar;D:\jbuilderx\jdk1.4\jre\lib\charsets.jar;D:\jbuilderx\jdk1.4\jre\lib\ext\dnsns.jar;D:\jbuilderx\jdk1.4\jre\lib\ext\ldapsec.jar;D:\jbuilderx\jdk1.4\jre\lib\ext\localedata.jar;D:\jbuilderx\jdk1.4\jre\lib\ext\sunjce_provider.jar;D:\jbuilderx\jdk1.4\jre\lib\im\indicim.jar;D:\jbuilderx\jdk1.4\jre\lib\im\thaiim.jar;D:\jbuilderx\jdk1.4\jre\lib\jce.jar;D:\jbuilderx\jdk1.4\jre\lib\jsse.jar;D:\jbuilderx\jdk1.4\jre\lib\plugin.jar;D:\jbuilderx\jdk1.4\jre\lib\rt.jar;D:\jbuilderx\jdk1.4\jre\lib\sunrsasign.jar;D:\jbuilderx\jdk1.4\lib\dt.jar;D:\jbuilderx\jdk1.4\lib\htmlconverter.jar;D:\jbuilderx\jdk1.4\lib\tools.jar" -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=real_trash:1535,suspend=y com.borland.samples.welcome.WelcomeApp

Error [2] in connect() call!
Socket transport failed to init.
Transport dt_socket failed to initialize, rc = -1.

但是编译和运行程序都上没有问题的,请问这到底是为什么.
另外,我在c盘装了jdk的,而且还装了一个jbuilder 9在c盘.情况就是这样

你的环境变量？？
只有jdk的用配置
jbuilder的统统不用配置

装jbuilder什么都不用配置，包括jdk，因为它自带了一个
