Read Zip File and output it to the Stream

Hi,
I really need help with this topic. I need to write a function which as input read the zip file (inside: jpeg, mp3, xml)
and as output provide the output Stream of this zip file.
public OutputStream readZipToStream(String sourceZipFile) { ....}
I've tried something....
public static OutputStream readZipToStream(String src, HttpServletResponse response) throws Exception {
 File fsrc = null;
 ZipOutputStream out = null;
 byte buffer [] = null;
 FileInputStream in = null;
 try {
 buffer = new byte[BUFFER_CREATE];
 fsrc = new File(src);
 out = new ZipOutputStream(response.getOutputStream());
 ZipEntry zipAdd = new ZipEntry(fsrc.getName());
 zipAdd.setTime(fsrc.lastModified());
 out.putNextEntry(zipAdd);
 // Read input & write to output
 in = new FileInputStream(fsrc);
 while (true) {
 int nRead = in.read(buffer, 0, buffer.length);
 if (nRead <= 0)
 break;
 out.write(buffer, 0, nRead);
 out.flush();
 in.close();
 } catch (IOException ioe) {
 logger.error("Zip Exception: " + ioe.getMessage());
 ioe.printStackTrace();
 throw ioe;
 return out;
 } But the problem with this code when it returns ( I called from servlet: bellow)
it ask user to save the file as servlet.jsp file. So I would have to rename it to zip file later.
What I want to achive is it would ask to save zip file from the stream as name of the original zip file (if that is possible)

OutputStream stream = null;
response.setContentType("application/zip");
target = mount_media + File.separator + "test_swf.zip";
try {
stream = ZipUtil.readZipToStream(target, response);
} catch (Exception ex) {
 System.out.println(ex.getMessage());
 } finally {
if(stream != null) {
 stream.close();
%>

Hi oleg_s ,
There's a contradiction of content in your JSP :
response.setContentType("application/zip");
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">The html part of your JSP seems useless for what you mean to do. Therefore, instead of a JSP, you should use a simple servlet to send your zip file.

Rename the zip file and send it using the Receiver Mail Adapter

Hi,
We have a custom module that will create multiple attachments. The result is then passed to the PayloadZipBean, which zips as per required.
When we output this to a file adapter, we provide the file name as say "zippedfile.zip" the result is as expected.
For example, if the custom module created 3 attachments with the names as file1.txt, file2.txt and file3.txt, the zip file zippedfile.zip, will contain 3 files as file1.txt, file2.txt and file3.txt.
The issue that we are facing is when we use the mail adapter, the zip file is getting renamed to file1.txt.zip i.e to say that it takes the name of the main payload from the custom module (file1.txt)
TextPayload txtpayload = message.getDocument();
txtpayload.setContentType("text/plain");
txtpayload.setName("file1.txt");
moduleData.setPrincipalData(message);
We tried using the MessageTransformbean but it doesn't seem to change the name of the file.
Not sure where we are going wrong. Is it that the output of the payloadzipbean cannot be used and altered by MessageTransformbean?
Is there any alternative as to rename the name of zipfiles and use it in the mail adapter?
Appreciate any help on this regard.
Regards,
Shabz

Solved.
use Transform.ContentDisposition - attachment;filename="youfilename"
Do read the mail adapter FAQ.
The parameter can vary for different mail client.

File Adapter to read Zip file and send it as input to another webservice

Hi,
I have the below requirement:
1. A service will generate 3 attachments and place it in a particular directory.
2. SOA service has to pick those 3 files and send those files as input to another custom application which will email.
Design :
1. First SOA will create an archive file of those 3 attachements and then file adapter will poll for that zip file in that location and send that file as a whole to the custom application.
Query:
Now my question, is the above design feasible? If so, how to configure the file adapter to pass the file as input to that custom application?
Kindly do the needful
Thanks,
Priya

You can accomplish this via java embedding activity...Create a java embedding, which will create a zip file.. this java code is easy to implement..
You can also do away with un-necessary polling file adapter.. and you can use "Synchronous File Read" operation of File Adapter.. For Sync Read, you'll have to pass the zip file name, which you can easily fetch from java embedding activity..
Let me know, if this doesn't work.

Hi Awen,
This is quite easy to do, you can merely use the "read from spreadsheet file" function to get a 2D array (2 columns and n rows) and then use the index array function to get whatever row/colums you want..
Hope the attached VI helps you

Panagon and MGETDOC Application:open a doc, the doc goes to .zip file instead of going to the doc directly

Application: FileNet content SG (Panagon) and MGETDOC(Web application)
Issue: when open a doc, the doc goes to .zip file instead of going to the doc directly. Only this issue happens for .xlsx,docs and pptx document.
Note: On all client machine, we are using office 2007 and IE8 browser
Cause: On 16th July 2013, . Net framework 4.5 is install on all our GI-D desktop machines. There after the issue is started .
Application Background: Applications built on .net framework 1.1 and it can support up to 4.0 version on client machine to view the documents through panagon and MGETDOC application. Panagon (Filenet content services) is
not supported in .net framework 4.5 and above.
Work around: After I had troubleshooting and tested with one of our system which has .net framework 4.5, IE8 does not support with HTML5 and tested with IE9 and Chrome, documents were able to open successfully.
I had removed .Net framework 4.5 uninstalled and able to open the documents w/o any issue. And also we had give the work around as if the doc goes to zip file, they open the doc by removing the . zip extension and they can save it as .xlsx or docx file and
they can able to open file.
Please let us know if you there is a fix to export the files through framework 4.5 and do contact us if you need further details, we shall discuss on the same. Thank you for your support. Request you to email @
[email protected]/[email protected]

Presumably you're using Safari?
You can change that in Safari Preferences (at least in 5.0.3, might be different in 5.1.x)
The checkbox at the bottom will do that for you. However! I strongly advise against permitting that; there have been, and no doubt will be again, malware that uses that to bypass authentication.
Just select Desktop as the default download location so you don't have to dig for the files.

Heyy man, i think, u did not get my problem.
all i have to do is:
i have to create a zip file, and we should secure it with password when creating. and whenever the user wants to open that zip file he should provide correct passowrd otherwise he could not read that file. So, we should check for that also.
Tanks for reply.

Reading a file and changing one part of the file

I am trying to read a file and then I want to change the first value on each line. The file I am reading is a .HEADER file. Which is just read in notepad I am just opening this like a txt file. I get no say at all how this file is created originally
I want to change the value on the first line the a new title plus the ext .dat. The file is below. This stays the same format just with different values.
ECG000 1 171 26112 9:14:56 23/04/2002
ECG000 8 43(0) 8 127 79 -24066 0 AED trace
I want to change the ECG000 to a new value eg Pat1.dat on the first line and Pat1 on the second line. When I read this file in and output to the dos window I get ECG000 0 0 0 and that is it. Any ideas why this is happening and how I can replace the values in the file??
     private void FileExt() throws IOException
          System.out.println("In function");
          BufferedReader br = new BufferedReader(new FileReader("c:\\Projects\\FirstSupport\\ECG000.HEADER"));
          String s;
          Vector data = new Vector();
          ECGFile = new FileWriter("c:\\Projects\\FirstSupport\\ECG.txt",true);
          System.out.println("Reading the file");
          while ((s = br.readLine()) != null)
          data.add(s);
          System.out.println(s);
          System.out.println("Finished");
          String label = s.substring(0, s.indexOf(" "));
          System.out.println(label);
          String newLabel = (label+".dat");
          System.out.println(newLabel);
     }

I think this is what you're looking for:     private void FileExt() {
          java.util.List data=new ArrayList();
          String s;
          try {
               BufferedReader br=new BufferedReader(new InputStreamReader(
                    new FileInputStream(new File("ECG000.HEADER"))));
               while ((s = br.readLine()) != null) {
                    data.add(s);
                    System.out.println(s);
               br.close();
          catch (FileNotFoundException fnfe) {
               System.out.println("Input file not found");
               return;
          catch (IOException ioe) {
               ioe.printStackTrace();
               return;
          ListIterator li=data.listIterator();
          try {
               PrintWriter ECGFile=new PrintWriter(new FileOutputStream(
                    new File("ECG.txt")));
               while(li.hasNext()) {
                    s=(String)li.next();
                    if (s.substring(0, 6).equals("ECG000")) {
                         s="Pat1.dat"+s.substring(6, s.length());
                    ECGFile.println(s);
               ECGFile.close();
          catch (FileNotFoundException fnfe1) {}
