java.util.zip.ZipException: error in opening zip file

Question

I have a Jar file, which contains other nested Jars. When I invoke the new JarFile() constructor on this file, I get an exception which says:

java.util.zip.ZipException: error in opening zip file

When I manually unzip the contents of this Jar file and zip it up again, it works fine.

I only see this exception on WebSphere 6.1.0.7 and higher versions. The same thing works fine on tomcat and WebLogic.

When I use JarInputStream instead of JarFile, I am able to read the contents of the Jar file without any exceptions.

Thanks for the hint about rezipping the file -- that fixed for me. — Bryan Larsen, May 04 '10 at 22:24
I've had this problem on Mac when Windows and Linux worked just fine. Using JarInputStream fixed the problem for me. — Boris van Schooten, Dec 20 '11 at 09:47
I have faced the same problem **on Tomcat Start UP** [catalina.properties]: `org.apache.catalina.startup.TldConfig tldScanJar` WARNING: Failed to process JAR [jar:../opensaml.jar!/] for TLD files `ZipException` to resolve this problem add [opensaml.~.jar](http://mvnrepository.com/artifact/org.opensaml/opensaml) into Application lib folder. — Yash, Apr 11 '16 at 12:19
Seems to be OS dependend. With Java 8 one of my jars is readable from MacOS and Linux but not with Windows 7. The jar is some 80 MBytes. Older jars are readable just fine on the same Windows 7. Which there would be better debugging options for this. — Wolfgang Fahl, Feb 24 '18 at 06:09

Make sure your jar file is not corrupted. If it's corrupted or not able to unzip, this error will occur.

I faced the same problem. I had a zip archive which java.util.zip.ZipFile was not able to handle but WinRar unpacked it just fine. I found article on SDN about compressing and decompressing options in Java. I slightly modified one of example codes to produce method which was finally capable of handling the archive. Trick is in using ZipInputStream instead of ZipFile and in sequential reading of zip archive. This method is also capable of handling empty zip archive. I believe you can adjust the method to suit your needs as all zip classes have equivalent subclasses for .jar archives.

public void unzipFileIntoDirectory(File archive, File destinationDir) 
    throws Exception {
    final int BUFFER_SIZE = 1024;
    BufferedOutputStream dest = null;
    FileInputStream fis = new FileInputStream(archive);
    ZipInputStream zis = new ZipInputStream(new BufferedInputStream(fis));
    ZipEntry entry;
    File destFile;
    while ((entry = zis.getNextEntry()) != null) {
        destFile = FilesystemUtils.combineFileNames(destinationDir, entry.getName());
        if (entry.isDirectory()) {
            destFile.mkdirs();
            continue;
        } else {
            int count;
            byte data[] = new byte[BUFFER_SIZE];
            destFile.getParentFile().mkdirs();
            FileOutputStream fos = new FileOutputStream(destFile);
            dest = new BufferedOutputStream(fos, BUFFER_SIZE);
            while ((count = zis.read(data, 0, BUFFER_SIZE)) != -1) {
                dest.write(data, 0, count);
            }
            dest.flush();
            dest.close();
            fos.close();
        }
    }
    zis.close();
    fis.close();
}

`zis.close(); fis.close();` should be in a finally clause - duh (or use try with resources) — Mr_and_Mrs_D, Dec 14 '15 at 18:51
This resolve my exact same problem! Problem was using ZipFile instead of ZipInputStream! Thx you very much <3 — CrazyProg, Nov 25 '20 at 10:48

It could be related to log4j.

Do you have log4j.jar file in the websphere java classpath (as defined in the startup file) as well as the application classpath ?

If you do make sure that the log4j.jar file is in the java classpath and that it is NOT in the web-inf/lib directory of your webapp.

It can also be related with the ant version (may be not your case, but I do put it here for reference):

You have a .class file in your class path (i.e. not a directory or a .jar file). Starting with ant 1.6, ant will open the files in the classpath checking for manifest entries. This attempted opening will fail with the error "java.util.zip.ZipException"

The problem does not exist with ant 1.5 as it does not try to open the files. - so make sure that your classpath's do not contain .class files.

On a side note, did you consider having separate jars ?
You could in the manifest of your main jar, refer to the other jars with this attribute:

Class-Path: one.jar two.jar three.jar

Then, place all of your jars in the same folder.
Again, may be not valid for your case, but still there for reference.

Thanks a lot for your response. However, I do not have a log4j.jar in the websphere Java classpath. — Sandhya Agarwal, Feb 23 '11 at 17:08

I've seen this exception before when whatever the JVM considers to be a temp directory is not accessible due to not being there or not having permission to write.

I solved this by clearing the jboss-x.y.z/server[config]/tmp and jboss-x.y.z/server/[config]/work directories.

I saw this with a specific Zip-file with Java 6, but it went away when I upgrade to Java 8 (did not test Java 7), so it seems newer versions of ZipFile in Java support more compression algorithms and thus can read files which fail with earlier versions.

Liquibase was getting this error for me. I resolved this after I debugged and watched liquibase try to load the libraries and found that it was erroring on the manifest files for commons-codec-1.6.jar. Essentially, there is either a corrupt zip file somewhere in your path or there is a incompatible version being used. When I did an explore on Maven repository for this library, I found there were newer versions and added the newer version to the pom.xml. I was able to proceed at this point.

I was getting exception

java.util.zip.ZipException: invalid entry CRC (expected 0x0 but got 0xdeadface)
    at java.util.zip.ZipInputStream.read(ZipInputStream.java:221)
    at java.util.zip.ZipInputStream.closeEntry(ZipInputStream.java:140)
    at java.util.zip.ZipInputStream.getNextEntry(ZipInputStream.java:118)
...

when unzipping an archive in Java. The archive itself didn't seem corrupted as 7zip (and others) opened it without any problems or complaints about invalid CRC.

I switched to Apache Commons Compress for reading the zip-entries and that resolved the problem.

On Windows7 I had this problem over a Samba network connection for a Java8 Jar File >80 MBytes big. Copying the file to a local drive fixed the issue.

In my case , my -Dloader.path="lib" contains other jars that doesn't need. for example,mvn dependency:copy-dependencies lists 100 jar files.but my lib directory contains 101 jar files.

Simply to overcome the ZipException's, i have used a wrapper for commons-compress^1.14 called jarchivelib^{written by thrau} that makes it easy to extract or compress from and into File objects.

Example:

public static void main(String[] args) {
        String zipfilePath = 
                "E:/Selenium_Server/geckodriver-v0.19.0-linux64.tar.gz";
                //"E:/Selenium_Server/geckodriver-v0.19.0-win32.zip";
        String outdir = "E:/Selenium_Server/";
        exratctFileList(zipfilePath, outdir );
}
public void exratctFileList( String zipfilePath, String outdir ) throws IOException {
    File archive = new File( zipfilePath );
    File destinationDir = new File( outdir );

    Archiver archiver = null;
    if( zipfilePath.endsWith(".zip") ) {
        archiver = ArchiverFactory.createArchiver( ArchiveFormat.ZIP );
    } else if ( zipfilePath.endsWith(".tar.gz") ) {
        archiver = ArchiverFactory.createArchiver( ArchiveFormat.TAR, CompressionType.GZIP );
    }
    archiver.extract(archive, destinationDir);

    ArchiveStream stream = archiver.stream( archive );
    ArchiveEntry entry;

    while( (entry = stream.getNextEntry()) != null ) {
        String entryName = entry.getName();
        System.out.println("Entery Name : "+ entryName );
    }
    stream.close();
}

Maven dependency « You can download the jars from the Sonatype Maven Repository at org/rauschig/jarchivelib/.

<dependency>
  <groupId>org.rauschig</groupId>
  <artifactId>jarchivelib</artifactId>
  <version>0.7.1</version>
