HowHow to Fix "java.util.zip.ZipException: Zip End Header Not Found" and Other Zip-Related Errors

If you're working with compressed files in Java and have come across errors like "java.util.zip.ZipException: Zip End Header Not Found," "java.util.zip.ZipException: not in gzip format," "java.util.zip.ZipException invalid block type," or "java.util.zip.ZipException: error in opening zip file," don't worry.

In this article, we'll explain what these errors mean and how you can fix them.

java.util.zip.ZipException: Zip End Header Not Found,java.util.zip.ZipException: not in gzip format, java.util.zip.ZipException invalid block type, or java.util.zip.ZipException: error in opening zip file

What Causes "java.util.zip.ZipException: Zip End Header Not Found" and Other Zip-Related Errors?

All of these errors are related to issues that can occur when Java tries to decompress a zip file. Specifically:

"java.util.zip.ZipException: Zip End Header Not Found" occurs when the end header of a zip file is missing or corrupted.
"java.util.zip.ZipException: not in gzip format" occurs when Java tries to read a file that is not in gzip format
"java.util.zip.ZipException invalid block type" occurs when Java encounters an invalid block type in a zip file.
"java.util.zip.ZipException: error in opening zip file" occurs when Java is unable to open a zip file

How to Fix "java.util.zip.ZipException: Zip End Header Not Found" and Other Zip-Related Errors

Check the integrity of the zip file. The first step in fixing any of these errors is to ensure that the zip file is not corrupted. You can use a tool like WinZip or 7-Zip to check the integrity of the file. If the file is damaged, you may need to download it again.
Use a different compression tool. If the zip file is not corrupted, the next step is to try using a different compression tool to create the zip file. Some compression tools may not create zip files that are compatible with Java's zip implementation. Try using a different tool to create the zip file and see if that resolves the error.
Use the correct file path. Make sure that the path to the zip file is correct. If the file is not found, the error may be thrown. Double-check the file path and try again.
Increase the buffer size. If none of the above solutions work, you can try increasing the buffer size when reading the zip file. This can be done by setting the "setBufferSize" method to a higher value. Increasing the buffer size can help Java read the zip file more efficiently and may fix the error.

Solution #

Make sure you are deploying a valid war or ear file. "Error in opening zip file" exception will be thrown if an attempt is made to deploy a corrupted EAR or WAR file.

Alternatively, You can validate your zip / jar / war file using below command.
Below command would fail with ZipException if the file is corrupt.

jar xvf corrupt.zip


C:\avi\tools\jars>jar xvf corrupt.zip
  created: elasticsearch-7.13.2/
  created: elasticsearch-7.13.2/lib/
java.util.zip.ZipException: invalid entry size (expected 13757513 but got 13754989 bytes)

        at jdk.jartool/sun.tools.jar.Main.main(Main.java:1681)

If there are so many jar files and you dont know which one is corrupt, you can run the below windows batch code.


@echo off
for %%i in (*.*) do jar -xvf %%i
