Hi,
I am trying to unzip a file of images to be later processed by JAI. When
I Do a CloseEntry() method on a zip Entry it throws this exception. Any
ideas? Are the files too big? I would think that java can handle any size

I can't help you directly - never seen this error before. However I can tell you that I have used zip format for transmission across the network, writing enormous zip streams as output and reading (and unzipping) them as input.
(Enormous means individual files of 30 megs)

Java.util.zip.ZipException: invalid entry size error -- help required

Hi all
I am sure this error would have been posted many number of times, but I would really appreciate if someone could help me with my problem. I am working on reading data from a .zip file, which in it has ~5GB data. All I am performing is a read operation through the piece of code specified below. This code worked well for .zip files handling till ~2.5GB
FileInputStream fis = new FileInputStream(filename);
BufferedInputStream bis = new BufferedInputStream(fis);
ZipInputStream zis = new ZipInputStream(bis);
StreamTokenizer tok = new StreamTokenizer( zis );
ZipEntry entry;
while((entry = zis.getNextEntry()) != null)
\\read from the zip file through the streamTokenizer
I just print what I read through the program, on the console.
But the error I get is

Hi,
I get the same exception while reading a ZIP file. The size if the ZIP file is just 82KB but I am reading it over FTP not sure if it makes any difference. I am using JDK 1.4.2_05. Here is the code I am trying to execute.
public class TestFTP {
public static void main( String[] argv ) throws Exception {
String inboundPath = "/transfer/inbound/";
FTPClient ftp = new FTPClient();
ftp.connect("123");
ftp.login( "123", "123" );
ftp.changeWorkingDirectory(inboundPath);
FTPFile[] zipFiles = ftp.listFiles("*.zip");
TelnetClient telnetClient;
for(int i=0;i<zipFiles.length;i++){
System.out.println(zipFiles.getName());
ZipInputStream zis = new ZipInputStream(ftp.retrieveFileStream(zipFiles[i].getName()));
for (ZipEntry entry = zis.getNextEntry(); entry != null; entry = zis.getNextEntry()){
System.out.println(entry.getName());

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.

I've written a replacement zip file creator class. Not much tested but it seems to work, however I've yet to try it with the version of WINZIP that rejected my previous attempts. Oh, and the stored dates are garbage.
* ZipOutputFile.java
* Created on 25 March 2004, 13:08
package zip;
import java.io.IOException;
import java.nio.ByteBuffer;
* Creates a ZIP archive in a file which WINZIP should be able to read.
* Unfortunately zip archives generated by the standard Java class
* {@link java.util.zip.ZipOutputStream}, while adhering to PKZIPs format specification,
* don't appear to be readable by some versions of WinZip and similar utilities. This is
* probably because they use
* a format specified for writing to a non-seakable stream, where the length and CRC of
* a file is writen to a special block following the data. Since the length of the binary
* date is unknown this makes an archive quite complicated to read, and it looks like
* WinZip hasn't bothered.
* All data is Deflated. Close completes the archive, flush terminates the current entry.

Java.util.zip java.util.jar API usage

I have been trying unsuccessfully for the past two days to be able to programatically add and extract files into and from a JAR using the API. I haven't found any API docs that cover the basics and I have been stumped using the nuggets that I have found on the Forum so far. Below is the code so far. Feel free to use what works in your programs, but if you find out how to get this to work. Sorry for the long post, but I gather this is a common problem that needs to be solved.

Are you using pack200 on signed jars? In the case you should normalize jars before signing, by packing and unpacking them.

Get java.util.zip.ZipException when start SOA server????

Installed SOA 11.1.1.5 on Windows 7 - all seemed to go well. Using XE, jdk_16025x64, rcu, WLS 10.3.5, SOA 11.1.1.5. After install, started the Admin server - no problem. Started the soa_server and get the following error messages when try to start it up. The same error message appears two times as the SOA_server comes up.
How do I fix this error?

does any body has the java code for
zipping files in a folder
hi guys,
actually i want to zip no of files in a folder .the folder can also have sub folder

Basically it takes the content from a BLOB column of the wpg_document table, unzip it using java.util.zip package, look for the file content.xml and parse it using Oracle XML toolkit.
Using an open source utility which replace java.util.package (http://jazzlib.sourceforge.net/) it works perfect because is a pure java application.
Best regards, Marcelo.
PD: I am using Oracle 9.2.0.2 on Linux.

The cause of errors was a dying Westen Digital drive, specially the 48G partition reserved only for $ORACLE_BASE (/dev/sdb3 mounted on /opt/oracle).
A simple quick scan of unmounted partition (badblocks -v /dev/sdb3) reported more than thousand new bad blocks (compared to the last scan six months ago). Although I strongly believe, specially in the case of WDC drives, that the best utility to "repair" bad blocks is the one that opens a window and prints the message: "Go to the nearest shop and buy a new drive", I was very curious to prove my suspicion just on this drive. After zero-filling the partition with dd, then formatting it (mke2fs -cc) and mounting again, the 11g installation and database creation (on the same partition) successfully completed, performing fast and smoothly. To make sure it was not a casual event, I repeated the installation once again with full success. The database itself is working fine (by now). Well, the whole procedure took me more than four hours, but I'm pretty satisfied. I learned once again - stay away from Western Digital. As Oracle cannot rely on dying drive, my friend is going tomorrow to spend a 150+ euro on two 250G Seagate Barracudas and replace both WDC drives, even though the first drive seems to be healthy.
In general there is no difference between loading correct data from good disk into bad memory and loading the incorrect data from dying disk into good memory. In both cases the pattern is damaged. For everyone who runs into the problem similar to this, and the cause cannot be easily determined, the rule of thumb must be:
1. test memory and, if it shows any error, check sockets and test memory modules individually
2. check disks for bad blocks regardless of the result of memory testing
Therefore I consider your answer being generally correct.

Java.util.zip.ZipException: a device attached to the system is not function

getting a java.util.zip.zipexception : a device attached to the system is not functioning error - what could cause such an error?
My program finds all zip files in an archive and then searches through them for xls files, which it extracts and re-locates.
I havent even a clue where to look for the cause of this exception but Ill attach at the bottom the code in the general vicitiny of the trigger so that you can get kind of an idea what Im trying to do, and if im lucky, even spot my problem. :) Thanks!!

Hey there a few things.
Make sure that you dont use fileseparators like you do. ("/")
Use the separator generated for your system.
Something like:
String sep = System.getProperty("file.separator");
You mentioned it work local, but not network.
Either you have plenty of harddrives or L: is a mapped drive.
Is it working at the mapped drive?
When you say on the network, how are you accessing the files?
Could it be possible for another user to lock a file, so you wont have access to it over the network?

Java.util.zip.ZIPException

We are using Oracle Application Server 10g (10.1.2) with AIX OS version 5.3 release 6.
We are getting error while deploying a "*.war" file. Below is the full error we have got during the installation.
Error starting from below.
Failed to deploy web application. File /tmp/dir1341.tmp/abc.war is not a jar file.
Resolution :
Base Exception:
java.util.zip.ZIPException
Error opening zip file /tmp/dir1341.tmp/abc.war
Error opening zip file /tmp/dir1341.tmp/abc.war
Kindly suggest the best provided solution for the same.
Also let us know about the error belongs Oracle AS application?
OR
AIX OS Level error?

Well as the error suggests, it is neither related to OracleAS nor AIX OS. It is complaining about the WAR file you are trying to deploy. Make sure your abc.war is a well formed WAR file. You can search google for tool to validate a war file.
Thanks

Error(5): java.util.zip.ZipException: invalid entry size (expected 2875 but

Hi all!
I'm getting this error when I try to execute my application in JDeveloper: Error(5): java.util.zip.ZipException: invalid entry size (expected 2875 but got 2845 bytes)
This started to happen after I had checkout my application to CVSNT.
Any help?
P.S. I'm using JDeveloper 10.1.3 with CVSNT 2.5

My cvswrappers file (CVSNT):
*.cab -kb
*.class -kb
*.doc -kb
*.dll -kb
*.ear -kb
*.exe -kb
*.exp -kb
*.fla -kb
*.gif -kb
*.gz -kb
*.jar -kb
*.jpg -kb
*.jpeg -kb
*.lib -kb
*.msi -kb
*.mso -kb
*.pdf -kb
*.pfw -kb
*.png -kb
*.ppt -kb
*.sit -kb
*.swf -kb
*.tar -kb
*.tlb -kb
*.vsd -kb
*.xls -kb
*.war -kb
*.wmz -kb
*.zip -kb Via Tortoise client I can add and commit zip (jar) files in binary format and everything is OK.
If I do that via Jdev, anybody who checkout that module from cvs have zip exception, because JDev didnt sent in binary format. How to setup that?
Thanx

Hi All,

Today I opened my working project in Jdeveloper 10.1.3 version and as I compile the project, it gives me this error in all Jsf - Jsp pages.
The line that it shows the above error in my pages is follows.
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
Any idea ? Till yesterday, I never got this error and all of sudden it started showing up.
Your help appreciated.
thanks,
pp

And just to add, nothing got checked out from repository (I mean CVS etc).
I have this project and Jdev on my windows laptop. I just opened it and started getting this strange error. any idea ?

Java.util.zip.ZipException Error

I created a jar file, and put in C:\tools
C:\tools>java -jar myjar.jar is working fine
However, if I try to run myjar.jar in other directories, then I have problems.
I already set the classpath:
SET CLASSPATH=.;%CLASSPATH%;C:\tools\myjar.jar;
Here's the error. Any ideas???
C:\>java -jar myjar.jar
Exception in thread "main" java.util.zip.ZipException: The system cannot find th
e file specified
at java.util.zip.ZipFile.open(Native Method)
at java.util.zip.ZipFile.<init>(ZipFile.java:112)
at java.util.jar.JarFile.<init>(JarFile.java:117)
at java.util.jar.JarFile.<init>(JarFile.java:55)

You always need to specify a proper file name when you use the -jar switch. If you are not in c:\tools you have to run with "java -jar c:\tools\myjar.jar".
Setting the classpath in particular doesn't help becuase the file name given to the -jar switch will override all settings for classpath. http://java.sun.com/j2se/1.4/docs/tooldocs/findingclasses.html#userclass
But since you now have myjar.jar in your classpath, you can run the application from any directory with "java your.main.ClassName" :)
