Importing org.apache.commons Java

Question

I've been trying to import the apache commons inside my jar, but can't see to do it. This code below is the code I'm using:

import java.applet.Applet;
import org.apache.commons.io.*;


public class Java extends Applet
{
  public void init()
  {
    String str1 = "testing.html"
    String str2 = System.getProperty("java.io.tmpdir");
     try {
            URL url = new URL("http://www.facebook.com");
            File destination = new File(str2 + str1);
            FileUtils.copyURLToFile(url, destination);
        } catch (IOException e) {
            e.printStackTrace();
        }
}
}

I compiled it with the command prompt:

set /p c=Please choose a signature name: 
keytool.exe -genkey -keyalg rsa -alias %c%
keytool.exe -export -alias %c% -file Certificate.crt
javac.exe Java.java -cp commons.jar
jar.exe cvf Java.jar *.class commons.jar
jarsigner.exe Java.jar %c%

Finally we got my HTML code to run it:

<applet width='100px' height='200px' code='Java.class' archive="Java.jar, commons.jar">
</applet>

Now when I run it, it wont download the file and place it in the temp folder. Why is that?

Answer 1

You appear to be trying to place the commons.jar inside your other JAR file; that won't work. You need to place it on the webserver in the same directory as your other JAR file. The browser can't download a file that doesn't exist on the server, and no code on the server is going to unpack that JAR.
