Zip extractAll undefined?

Question

I'm trying to unzip this file using Java.I found this guide: What is a good Java library to zip/unzip files? But I'm getting an error: The method extractAll(String) is undefined for the type ZipFile

Code:

String dir = System.getProperty(user.dir);
String source = dir+"/file.zip";
                String destination = dir;

                try {
                    ZipFile zipFile = new ZipFile(source);    
                    zipFile.extractAll(destination);
               } catch (ZipException e) {
                   e.printStackTrace();
               }

EDIT: I found the solution. It's rather embarrassing, but I imported the wrong one -.-

@SašaŠijak I'm just using the code like he did, and Daniel that's the whole error message. — Paludan, Dec 13 '13 at 09:47
We can't know if you if you are "using the code like he did". The imports are important here because zip4j as well as the java libraries themselves contain a `ZipFile` class. — Viktor Seifert, Dec 13 '13 at 09:53

See to it that you have the right jar http://www.lingala.net/zip4j/download.php

I just extracted the jar there is a method in ZipFile.class

  public void extractAll(String destPath)
    throws ZipException
  {
    extractAll(destPath, null);
  }

So please check that you have proper import from proper jar file, that all there is to it.

I just had a look at source code of Zip4j (version 1.3.1). The method extractAll definitely exists. Make sure that the zip4j-jar is on your classpath and that you are using the latest version.

I downloaded the one from the website, how do I add it to my classpath? – Paludan Dec 13 '13 at 09:51
Ok apparently I already have it in my classpath, but I'm still receiving the error o.O – Paludan Dec 13 '13 at 09:53
