Java Plug-in 1.4.0 throws an IllegalStateException: zip file closed

Cross-posting to reach a wider audience:
Java Plug-in 1.4.0 throws an IllegalStateException: zip file closed
Author: remyb Jul 23, 2002 6:36 AM
A IllegalStateException is thrown when the class loader
try to load a class from my applet JAR file.
The applet is embedded in a JSP page which use the Plug-In 1.4.0.
That JSP is hosted by Tomcat 4.0.1.
The applet JAR file is signed with a self-signed certificate.
The applet has been compiled with JDK 1.4.0.
The jar has been put in the Plug-in cache successfully.
Here is the stack trace I got in the Java Console ...

I've got a very similar error, but unfortuneatly I don't have an answer yet. The only difference is that my Applet is embedded in a standard HTML page, and loaded via Apache. Once the Applet runs, it then communicates with the servlet via Tomcat. I also exchange data with another server task via CORBA.
But everything else is the same, self-signed applet, applet compiles successfully, and jar is being put in the Plug-in Caceh successfully.
I have narrowed the problem down a bit, and maybe you can tell me if you're in a similar situation:
In my case, I need to encrypt the data that I'm sending through CORBA, so I create a Cipher object using Cipher.getInstance(). This method call seems to be the catalyst of my troubles. No matter where I move that call in my code, the next time the code tries to instantiate a class defined in my applet jar file after that "getInstance" call, I get the "zip file closed error." It's like the classloader is confused, because the Cipher.getInstance method would be accessing a different jar file or something. Are you trying to do something similar? Maybe not creating a Cipher, but creating some other object defined outside your own jar-file?
To top it off, if I disable caching in the Plugin control panel, everything works fine. But that's not really an option for me, since it slows things down a lot, and I can't make all my users go into their control panels and disable caching. But at leasts it makes me confident that there's not a problem with my code.
In my latest attempt to circumvent this problem, I even put the Cipher.getInstance() call in a static initializer. Here's the stack trace from that attempt:
java.lang.IllegalStateException: zip file closed

at sun.applet.AppletPanel.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
In other words, since the getInstance method is in a static initializer, the next thing to run is the applet.init(), which is what is failing now. If I move the Cipher.getInstance method into the client constructor, the next time I instantiate a new object, I'll get the error there.
Has anybody else seen anything like this? Or does anybody know how I can flush the Cache from the applet code? Or can I reset the ClassLoader in some way in the code?
Thanks,
Steve

Well, I finally came to a solution that is acceptable at least to me, if not ideal. I've started using the BouncyCastle lightweight API. This makes my code somewhat more complicated, and I had to bundle up all the BouncyCastle classes that I'm using into a jar file, and download that to my applet along with my client jar file (after signing the jar files). Using this Lightweight API bypasses the Cipher.getInstance() method all together, and is a little harder to use, but at least everything is working consistently now.
I still believe this to be a bug either in the ClassLoader or the Cipher.getInstance() method. I intend to try to write a test applet that reproduces the error in a more simple way and if I can pull that off, I'll submit a bug report to Sun.
Thanks to all who responded!!

Excel 2013 (office 365) crashes every time I opened a excel file directly from Browser or zip file.

Hi guys,
I got a problem with my Office 365 that every time I open an office file from IE/chrome browser (i.e. click the document link and save the file to local, open it in the browser after download completed) or under a zip file, no matter it is an excel file
or word document, the Excel/Word crashes. The Excel/Word will ask me to repair the file if I open the file again. The file will be closed automatically after the repair, when I open the file again it will told me the excel/word itself has just successfully
registered and ask me to close and re-open the excel again in order to enable editing the file. This is extremely inconvenience, I have to open this file 4 times to edit my file.
Could anyone here can help me to resolve the problem?
Many thanks.

Hi,
According to your description, Excel seems not crash when you opened a local Excel/Word file directly. Where do you store these file? OneDrive, SharePoint or other?
If possible, please let me see the screenshot of the error dialog.
Moreover, please open Event Viewer to check whether there's any error about the Excel/Word crash issue.
Press Win + R, type "eventvwr" in the blank box, press Enter. In the Event Viewer, browse to Windows Logs -> Application, there may be some errors after the crash.
To protect your privacy, you may send the error logs to
[email protected], we will try to find the cause.

George Zhao

Writing objects with in zip files

Hi,
I am trying to write an object into a zip file :
ZipOutputStream zout=new ZipOutputStream(new FileOutputStream("test.zip");
ZipEntry ze=new ZipEntry("test.dat");
zout.putNextEntry(ze);
ObjectOutputStream out=new ObjectOutputStream(zout);
out.writeObject(obj);
out.close();
zout.closeEntry();
zout.close();
The above code is within a try-catch block.
It is compiling correctly.
But it is throwing an exception just after executing "zout.closeEntry()".
The exception is "java.io.Exception: Stream Closed".
I am using JDK 1.3.
Can anyone help me.
Indra.

Hi Indra,
I'm sorry it didn't work. I would try to simulate that problem but I really don't have time right now (but I will).
What you can do is to try to create that zip file in 2 steps, first just serialize the objects in a ordinary file and then read from that file and create a zip file. Of course you'll have to do the same to get your objects out from the zip file.
If the file is not too big you can use a ByteArrayOutputStream instead of a FileOutputStream for the first file.
hope it will work,
Gabe

Error in reading the contents of a zip file

EHello Experts,
I want to read the contents of a zip file.I have written the following program which reads the contents of a file named "index.xml" which resides in ReadZip.zip.My problem is , it is reading only the first line of that file & after that it is giving this error.

            ZipEntry ze;
            while ((ze = zis.getNextEntry()) != null) {

                                new InputStreamReader(zis));
                        String line;
                        while ((line = br.readLine()) != null) {
                            System.out.println(line);
                        br.close();
        } catch (IOException e) {
            e.printStackTrace();
}It seems that zis is getting close after reading the first entry of file.I am unable to guess the reason for this.Please help.Thanx in advance.

Problem in ZIP file encryption

Hi Folks,
I am facing a problem while encrypting and decrypting a ZIP file. The result file is corrupted.
If i encrypt .txt and .doc files, i am able to get them in decryption. But problem with ZIP files. What could be the reasone?
I am using AES algorithem.
Key Generator code is:
================
KeyGenerator kgen = KeyGenerator.getInstance("AES");
kgen.init(128); //128 bitskey = kgen.generateKey();
Encryption:
========
Cipher ecipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
//paramSpec is a Initialization Vector
ecipher.init(Cipher.ENCRYPT_MODE, skey, paramSpec);
FileInputStream in = new FileInputStream("c:\\encryption\\Source.zip");
FileOutputStream out = new FileOutputStream("c:\\cipher\\cipher.enc");
OutputStream cout = new CipherOutputStream(out, ecipher);
int numRead = 0;
while ((numRead = in.read(buf)) >= 0) {
cout.write(buf, 0, numRead);
Decryption:
========
Cipher dcipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
dcipher.init(Cipher.DECRYPT_MODE, skey, paramSpec);
FileInputStream fis = new FileInputStream("c:\\cipher\\cipher.enc");
InputStream in = new CipherInputStream(fis, dcipher);
FileOutputStream fos = new FileOutputStream("c:\\encryption\\Result.zip");
int numRead = 0;
while ((numRead = in.read(buf)) >= 0) {
fos.write(buf, 0, numRead);
}

i closed them in the program. i just pasted important lines of my program.You have a program that does not work and you don't know why yet you feel confident enough in your diagnosis to show just the lines where you think the problem lies. I'm betting that you are closing the wrong streams but of course I am guessing since I can't see the code that matters.
Good luck.

Tried~
The problem is still here~ >___<
Anyway, thanks for information sharing~
The message is:
Cannot open file: it does not appear to be a valid archive.
If you downloaded this file, try downloading the file again.
The problem may be here:
if (fos != null)
fos.close() ;
if (bos != null)
bos.close();
if (zos != null)
zos.close();
if (file != null)
file = null ;
The fos is closed before bos so the last buffer is not
saved.
zos.close() is enough.

How to unzip a zip file within another zip file

I've got code that successfully processes a file within a zip file.
But now the zip file can also contain other zip files. How can I
process a zip nested within a zip without actually extracting the
files? It looks like I need a ZipFile object to be able to take
advantage of the zip classes for reading zip entries. But the
ZipFile methods want as an argument an actual file, as opposed
to some object in memory. I can read the 'inner' zip file into a
ZipInputStream object, but then how do I make that available for
processing as a ZipFile? I've searched all over and cannot find
anything anywhere that talks about working with nested zip files.
Does anyone have any sample code that does this? Thanks!

I have successfully done it.
You cannot have the code - it is proprietary.
However here are a few pointers:
o Use ZipStreams rather than ZipFile.
o ZipStream is just a filter on a stream, so you can have a zipstream open, read a ZipEntry, then ask for a substream for the stuff up to the next ZipEntry. Put a second ZipStream on that substream.
o As I recall you have to watch out that your inner ZipStream does not do a close. (Everything will get closed.) Instead, there is another ZipStream method that will close without closing all the underlying streams.
Hope this helps.

Can't open the Zipped file

Hi
I am making a zip file using GZIPOutputStream. But I am not able to open the zip file that is created using win zip.The size of the zipped file is 81 KB and the input file is 3,245 KB.I have closed all the streams still I am not able to figure out the problem.Any idea where I am going wrong ? Any help would be greatly appreciated.
Here my code goes:
import java.util.zip.*;
import java.io.*;
public class ZipFile
     public static void main(String[] args) throws FileNotFoundException,IOException
          ZipFile("D:\\Java\\Test\\INPUTXML_bkp_1.xml");
     public static String ZipFile(String fileName) throws FileNotFoundException,IOException
          String name = fileName.substring(fileName.lastIndexOf('\\') +1 ,fileName.lastIndexOf('.'));
          String filePath = fileName.substring(0,fileName.indexOf(name));
          String newFileName = new StringBuffer(name).append(".zip").toString();
          FileOutputStream outputStream = new FileOutputStream(newFileName);
          GZIPOutputStream zipOutputStream = new GZIPOutputStream(outputStream);
          FileInputStream inputStream = new FileInputStream(fileName);
          byte[] temp = new byte[10000000];
          int counter = inputStream.read(temp,0,temp.length);
          zipOutputStream.write(temp,0,counter);
          inputStream.close();
          zipOutputStream.finish();
          zipOutputStream.close();
          return newFileName;
Thanks
Ritesh

Thanks for the reply.
I changed my code to look like this:
import java.util.zip.*;
import java.io.*;
public class ZipFile
     public static void main(String[] args) throws FileNotFoundException,IOException
          ZipFile("D:\\Java\\Test\\INPUTXML_bkp_1.xml");
     public static String ZipFile(String fileName) throws FileNotFoundException,IOException
          String name = fileName.substring(fileName.lastIndexOf('\\') +1 ,fileName.lastIndexOf('.'));
          String filePath = fileName.substring(0,fileName.indexOf(name));
          String newFileName = new StringBuffer(name).append(".zip").toString();
          FileOutputStream outputStream = new FileOutputStream(newFileName);
          ZipOutputStream zipOutputStream = new ZipOutputStream(outputStream);
          ZipEntry zipEntry = new ZipEntry(fileName);
          zipOutputStream.putNextEntry(zipEntry);
          zipOutputStream.finish();
          zipOutputStream.close();
          return newFileName;
Now I can atleast open the zip file. But the problem is the size of the file is 0 kb. Probably because, I am not populating the Zip entry. Can u pls let me know how do I do that.
Thanks

Adding image to a zip file

Hi all,
I am trying to work out a servlet that creates an on-the-fly zip file. I am trying to add an image in this zip file and then I want to prompt user to download the created zip file. It is creating the zip file -it prompts the user and downloads the zip file... but when I open the downloaded zip file -the image is not found to be added in it. Please help, here is the code:
package servlets;

     ServletContext servletContext = null;
     HttpServletResponse res=null;

               try {
                    FileInputStream input = new FileInputStream(img);
                    zout = new ZipOutputStream(new FileOutputStream(img));
                    zout.putNextEntry(new ZipEntry("image.jpg"));
                    int len;
                    while ((len = input.read(b)) > 0) {
                    zout.write(b, 0, len);

                    input.close();
                    System.out.println("closed");
               } catch (Exception e) {
                    System.out.println("Exception occurred");
                    res.setContentType("text/html");
                    out.println("<html><head><title>Error</title></head>");
                    out.println("<body><b>");
                    out.println("An error has occured while processing "
                              + "<br>");
                    out.println("Here is the exception: <br>" + e + "<br>");
                    e.printStackTrace(new PrintWriter(out));
                    out.println("</body>");
                    out.println("</html>");

Problem in deleting Zip files unzipped using java.util.zip

I have a static methos for unzipping a zip file. after unzipping the file when i am trying to delete that file using File.delete()its not getting deleted. but when methods like exist(). canRead(), canWrite() methods are returning true what can be the possible problem ? i had closed all the streams after unzipping operation Please go through the following code.
public static boolean unzipZipFile(String dir_name, String zipFileName) {
try {
ZipFile zip = new ZipFile(zipFileName);
Enumeration entries = zip.entries();
while (entries.hasMoreElements()) {
ZipEntry entry = (ZipEntry) entries.nextElement();
// got all the zip entries here
// now has to process all the files
// first all directories
// then all the files
if (entry.isDirectory()) {
// now the directories are created
File buf=new File(dir_name,entry.getName());
buf.mkdirs();
continue;
}// now got the dirs so process the files
entries = zip.entries();
while(entries.hasMoreElements()) {
// now to process the files
ZipEntry entry = (ZipEntry) entries.nextElement();
if (!entry.isDirectory()){
File buf=new File(dir_name,entry.getName());
copyInputStream(
zip.getInputStream(entry),
new BufferedOutputStream(
new FileOutputStream(buf)));}
} catch (IOException e) {
e.printStackTrace();
return false;
return true;
now i am trying to call this method to unzip a zip file
public static void main (String arg[]){
unzipZipFile("C:/temp","C:/tmp.zip");
java.io.File filer = new File("C:/tmp.zip");
System.out.println (filer.canRead());
System.out.println (filer.canWrite());
System.out.println (filer.delete());
Please tell me where my program is going wrong ?

Thanks .. the problem is solved... i was not closing the Zip file .. rather i was trying to close all the other streams that i used for IO operaion ... thanks a lot

Email internal table as zip file

Hello everyone
I spent several days to have a full example on how to convert an internal table has ZIP file than send it by email.
I found several example to upload file from the OS and than convert it to ZIP to save it after. But nothing from the current internal email.
So, for the benefit of everybody who that can interrest, here is the code I did. Feel free to optimize it and post the new version here.

Hello Daniel,
Thank you very much for this post, it is quite helpful. However, I have followed your template very closely and my file will not send. I am not an advaned ABAP programmer, but have a good knowledge of programming in general...here's a bit of my code related to this...
*-Create table body
LOOP AT (internal table) INTO (structure)
(Fill lv_line with one line of string based on structure)
    CALL FUNCTION 'SCMS_STRING_TO_XSTRING'
      EXPORTING
        text = lv_line
      IMPORTING
        buffer = lv_xline
    CONCATENATE lv_xcontent lv_xline INTO lv_xcontent IN BYTE MODE.
ENDLOOP.
*-Create zip xstring
CREATE OBJECT lo_zipper.
CALL METHOD lo_zipper->add
    EXPORTING
      name = 'AHReport.zip'
      content = lv_xcontent.
CALL METHOD lo_zipper->save
    RECEIVING
      zip = lv_xzipcontent.
*-Convert zip xstring to binary
CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'
    EXPORTING
      buffer = lv_xzipcontent
    TABLES
      binary_tab = lt_data.
*-    Add attachment
      TRY.
        CALL METHOD l_document->add_attachment
            EXPORTING
              i_attachment_type = 'ZIP'
              i_attachment_subject = 'Report'
              i_att_content_hex = lt_data.
