通过命令行将URL添加到classpath

Question

I'm trying to achieve the equivalent to this:

java.exe -cp "C:\my_test\my_jar.jar;C:\my_test\lib\*;" com.test.Main

but using an URL like this:

 java.exe -cp "http:\\192.168.1.12\my_test\my_jar.jar;http:\\192.168.1.12\my_test\lib\*;" com.test.Main

The error is: Could not find or load main class , but if I look into http:\\\\192.168.1.12\\my_test\\my_jar.jar I can see my Main class there. Is there any way I can do this via command line ?

PS: I can reach http:\\\\192.168.1.12\\my_test\\my_jar.jar via browser

Answer 1

The classpath is composed of jar files and directories. Not of http URLs. You'll have to programmatically create a UrlClassLoader to load classes from a server that way.
