I use JBuilder2 to compile an application generated by application wizard. It outputs some class files. What I want to know is how can I use Java virtual machine to load the application and run it. I setup the environments correctlly. But, when I use jre.exe to run the application in command line, an error information will show: Class not found. I began to learn Java 3 days ago. So this information confuses me. Is there anyone who can tell me how to do ? I have referenced the help documents, but it does not work.

把class所在的路径 设到classpath中
如果是jdk1.3只用设path中

C:\Borland\jbuilder5\jdk1.3\bin\javaw -classpath "D:\Kare\AutoAnswer\classes;C:\Borland\jbuilder5\lib\jbcl.jar;C:\Borland\jbuilder5\lib\dx.jar;C:\Borland\jbuilder5\lib\beandt.jar;C:\Borland\jbuilder5\jdk1.3\demo\jfc\Java2D\Java2Demo.jar;C:\Borland\jbuilder5\jdk1.3\jre\lib\i18n.jar;C:\Borland\jbuilder5\jdk1.3\jre\lib\jaws.jar;C:\Borland\jbuilder5\jdk1.3\jre\lib\rt.jar;C:\Borland\jbuilder5\jdk1.3\jre\lib\sunrsasign.jar;C:\Borland\jbuilder5\jdk1.3\lib\dt.jar;C:\Borland\jbuilder5\jdk1.3\lib\tools.jar" yourPackage.mainclassname

这是用JB5，JB2只需将相应的.jar及其路径改一下就可以了，建议你用JB5吧

My English is not good. But I key Chinese more slowly than I key English.
So, that is why I like communicate with you in English.
