java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver

kimho's jsp 를 하다가
java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver 에러가 났다.

C:\Documents and Settings\han58>javap org.gjt.mm.mysql.Driver
Compiled from "Driver.java"

}

이걸 봐선 연결은 된거 같은데..
java.lang.ClassNotFoundException: org.gjt.mm.mysql.Driver 에러가 자꾸만 났다.

Hi!

but where will be the mysql jar file
there is no such directory like lib in the mysql
folder

As you probably already found out, the mysql jar file needs to be on the classpath of your java application when you run it.

For example something like:

C:> java -cp mysql.jar MyApplication

:)

Or the mysql jar file could be in your web-app's lib directory if you're running one. For example under Tomcat:

/Tomcat_home/webapps/your-web-app/WEB-INF/lib <--- mysql.jar there!

I hope this helps :)

이걸 보고 lib 폴더를 만들어서 jar 파일을 넣었더니 해결이 되었다.
