How to unzip multiple files from a bytearray to place them inside Cabinets

vsoman1984

Hi All,

The following are the steps i followed for a requirement of mine.

1) Obtained multiple byte arrays containing contents and packed them all inside an arraylist.These byte arrays are of the documents inside my Cabinet which were multiselected.

byte[] inOnclick;
  ArrayList<byte[]> bcontainer = new ArrayList<byte[]>(); 

  public void onClickSendToServices(Control control, ArgumentList args)
  {   
       for( int k=0;k<vals.length;k++)
      {
     System.out.println("This is value of k " + k );    
     // Get ByteArray for each file and assign it into created ArrayList Object ABC
               inOnclick = getContent(m_sessionManager,reponame,vals[k]);
             // ArrayList.Add(ByteArray [i] file
             bcontainer.add(inOnclick);             
       }

2) This Arraylist 'bcontainer' was then converted onto a byte array since i needed to zip this (collection of bytearray contents) and the zip functionality needed byte array as input parameter.

String tempStringFrmArrList ;
byte[] test;
tempStringFrmArrList = bcontainer.toString();
test = tempStringFrmArrList.getBytes();

3) Then i passed a filename and the above generated byte array 'test' onto a function zipping it by the call

byte[] collectzip;
String testfilename="TestFile.zip"
collectzip = zipBytes(testfilename,test);

4) This is the zipBytes function.

public static byte[] zipBytes(String filename,byte[] input) throws IOException { System.out.println("This is inside the zipBytes function"); ByteArrayOutputStream baos = new ByteArrayOutputStream(); ZipOutputStream zos = new ZipOutputStream(baos); ZipEntry entry = new ZipEntry(filename); entry.setSize(input.length); zos.putNextEntry(entry); zos.write(input); zos.closeEntry(); zos.close(); return baos.toByteArray(); }

5) Now i want to unzip the byte array recieved post the zipping namely " collectzip" to emulate a subsequent functionality and here is my question.
How can i unzip this bytearray to iteratively list down each bytearray contained inside it. i.e. list out the contents i had packed into the ArrayList to ulimately save them as separate files in a folder inside the CMS?
Will the name of the zipfile "testfilename" suffice to obtain the individual contents inside them?

Looking forward for your valuable suggestions.

Thank You
Regards
