ZIP File has damaged contents - Multiple file download

Question

Hi,
I am using ZIP API in Web Dynpro JAVA for multiple file download scenario.
Issue:--->
Some files are not opening correctly after unzipping the ZIP file.
Example-1: some PDF files gives out message that " "
Example-2: Also, a JPG file shows only upper half of the image.
So in all, the content of generated ZIP file are damaged.
Any idea why this is happening?
Thanks & regards,
Amey

Answer 1

And this is the code I'm using:-
Unzipped PDF files give this error --> There was an error opening this document. The file is damaged and could not be repaired
for(int i = 0; i < l_int_NodeSize; i++){
     g_SearchOutputEle = g_SearchOutputNode.getCtx_vn_SearchOutputElementAt(i);
     java.net.URL url = new URL(g_SearchOutputEle.getFileUrl());
     java.net.URLConnection urlConnection = url.openConnection();
     java.io.InputStream inputStream = url.openStream();
     int arraySize = urlConnection.getContentLength();
     byte[] byteArray = new byte[arraySize];
     DataInputStream dis = new DataInputStream(inputStream);
     dis.read(byteArray);
     ZipEntry zipEntry = new ZipEntry("Name-"+i);
     zipEntry.setSize(byteArray.length);
     zos.putNextEntry(zipEntry);
     zos.write(byteArray);
     zos.closeEntry();
zos.close();
byte[] byteOutArray = baos.toByteArray();
IWDResource resource = WDResourceFactory.createResource(byteOutArray, "Downloads.zip",WDWebResourceType.UNKNOWN);
String urlString = resource.getUrl(WDFileDownloadBehaviour.ALLOW_SAVE.ordinal());
IWDWindow win_MultiFileWindow = wdComponentAPI.getWindowManager().createNonModalExternalWindow(urlString);
win_MultiFileWindow.setWindowSize(0,0);
win_MultiFileWindow.show();
