I am trying to unzip a zip file attachment. but, unable to unzip the attachment and process all the internal files in the zip file. I want to do this using an email handler class.

You can do this natively in Apex using the Zippex library which is open source. https://github.com/pdalcol/Zippex

Your code would be similar to this:

Blob zipBlob; //This needs to contain the zip file

Zippex myZip = new Zippex(zipBlob);

//Loop through the files in Zip and process them
for (String fileName : myZip.getFileNames()) {

    Blob fileData = myZip.getFile(fileName);

    //Process fileData here.

}

Unfortunately, there is no native zip support in APEX right now. But you can help yourself using a very good Javascript zip tool like http://stuk.github.io/jszip/

On how to use it, look at http://andyinthecloud.com/2012/11/04/handling-office-files-and-zip-files-in-apex-part-1/

    Close, but it won't work for apex code. However, I'm working on a batch class version since the new ten minute limit was introduced. – sfdcfox Jul 12 '14 at 15:04
  • @sfdcfox sounds very interesting. Will you share your approach? Can you elaborate on how you do it or post a link? – Uwe Heim Jul 12 '14 at 15:11
