我无法在项目中包含jar文件

Question

I tried to use a sourceforge library in my program. On my computer I use Eclipse, and I easily add the jar files to my project. Now, I want to move the code to another computer.

I tried an executable jar file, but the problem is I cannot debug it on the new computer. So, I decided to move the source code and compile it there.

I tried the following but defeated in all of them: (all in Windows Command prompt)

1. Copy the jar files in the /lib/ext folder of my jre folder and add this folder to classpath
2. javac -cp ".\\lib\\*.jar" src/*.java
3. javac -cp "./lib/*.jar" src/*.java

In all of them the classes that are defined in the library jar files can not be recognized by java! Actually the package doesn't find...

Any idea? Any stupid thing that I am doing?

The correct wildcard for matching all jars in a directory is just

-cp "dir/*"

Please see the Understanding class path wildcards section of this page: Setting the classpath
