            Generating Big Zip with streams[with zip4j] and uploading it to s3
            Asked 2022-Mar-25 at 14:06

            I'm working on generating a zip file that has to compress around 2000 documents that are around 1GB in total and after that to upload the zip file in s3 bucket.

            I'm using net.lingala.zip4j which is a really nice Java library for handling Zip files. Based on the documentation:https://github.com/srikanth-lingala/zip4j I'm using the stream handling part of it. The code looks almost similar to the one from the documentation:

            Funny enough, this was on the local machine while I got OutOfMemoryError during the zip generation.

            In testing environment, I got OutOfMemoryError during the retrieval of the documents. So Hibernate was complaining too. This was with a step before the generation. Probably this happened since local machine has 16GB and testing env only 1GB.

            So the solution was build based on the following steps:

            1. retrieve the files in batches with Hibernate, and (flush/clean) transactional entityManager, in order to force Hibernate to not keep in memory all the files. The Batch size was: 50 documents.
            2. Adapt the code for the zip4j compression with Aws multipart upload, in order to compress and upload only one batch of files, and reset the buffers afterwards, to avoid OutOfMemory.

            Step2 was designed and adapted based on: https://www.bennadel.com/blog/3971-generate-and-incrementally-stream-a-zip-archive-to-amazon-s3-using-multipart-uploads-in-lucee-cfml-5-3-7-47.htm

            So the code from the initial question became as follows:

            ItemTouchHelper - Can't scroll RecyclerView, Swipe doesn't work
            Asked 2021-Dec-25 at 15:17

            Well, at the beginning of the Implementation of ItemTouchHelper, I chose to use only the Swipe function from it. Everything worked - with the help of Swipe I could delete items in RecyclerView etc. But then I thought I'd add up-down movement so that the user could change the order in which the item appears in the list. Then the problems began - the user can change the order in which items are displayed, but can no longer:

            • Scroll RecyclerView (even if changing item up-down position is disabled)
            • Swipe functions have stopped working - onSwiped does not return the side (ItemTouchHelper.LEFT, ItemTouchHelper.RIGHT) in which the item was swiped

            I changed the View on which is trigger OnStartDragListener from _view to just ImageView and I can scroll now but there are now other problems:

            • Swipe works on that ImageView too - I want to be able to swipe item whereever user click on item (_view)
            • Swipe functions still doesn't work - onSwiped does not return the side (ItemTouchHelper.LEFT, ItemTouchHelper.RIGHT) in which the item was swiped

            Video how the problem looks

            Zipping CSV file using Java produces zip file with lesser bytes
            Asked 2021-Oct-19 at 05:50

            I've a simple Java code which creates a ZIP file using one CSV file. The code is working fine and produces the zip file just right. But, the zip file size(bytes) are different that the one I create using Windows zipping tool or something like 7zip. I need to know if there is any Java library which can create zip file similar to how windows zips the file.

            Background - We send this zip file to a REST API which fails sometimes with 403 - Forbidden error but when we zip the file using windows zipper or 7zip, it works fine. So, I would like to know if there is any way to zip file in Java the way windows/7zip does.

            I've tried -

            1. Inbuilt Java functions for zipping
            2. Apache commons compress
            3. zip4j

            You are not really creating a zip file, you are creating a file with the .zip extension and simply copying to it the original CSV file value.

            Correctly migrating from JDK-8 to JDK-11 for JAX-WS libraries
            Asked 2021-Oct-01 at 16:39

            I am developing a couple of integrations (as Maven projects) between several defect management systems, one of which exposes services through WSDL, forcing me to consume them through WS. For the latter I succesfully developed the code for JDK-8 and everything works.

            I am now in the middle of JDK migration from 8 to 11 and need to update the integration that makes use of WS. I understood that in Java 11 some EE libraries (including JAX-WS) were removed. I then surfed the Web in order to get rid of this problem, but after a couple of days of tests and cut-and-paste of depenendencies I still have the same problem: cannot instantiate the WS to interact to the final server (that is a CA SDM 14.1).

            Sorry, I don't think there is a library that will do exactly what you want.

            • zip4j ZipFile can only open a File or a String pathname.

            • Java SE ZipFile can only open a File or a String pathname ... and doesn't support encrypted entries.

            • Java SE ZipInputStream does support an InputStream, but doesn't support encrypted entries.

            • Apache Commons ZipFile does support seekable input streams (and channels), but not InputStream. And it doesn't understand encrypted entries.

            • Apache Commons ZipInputStream works with any InputStream but it doesn't understand encrypted entries.

            So what are the options?

            The simplest option would be to copy the InputStream contents to a temporary file and then use zip4j ZipFile as per the code in your question. When you are finished, delete the temporary file.

            In theory, you ought to be able to use Java SE ZipInputStream and scan the entries to check the FileHeader for each file. (Bit zero of the "general purpose bit" field tells you if the file is encrypted.) The problem is that ZipEntry doesn't expose the information.

            However, Apache's ZipInputStream class (which can read an InputStream!), exposes the general purpose bit field. So this would provide a way to test if any of the files in the ZIP is encrypted. If that is all you need, then you have another possible option.

            File.createTempFile("export_", ".zip") creates a file on disk while File("somefile.zip") only points to a file but does not create it. zip4j seems to check if the file exists and if it exists it expects the file to be a valid zip file. That's why using ZipFile(file) fails if file was created with createTempFile().

            zip4j before 1.3.3 is vulnerable to directory traversal, allowing attackers to write to arbitrary files via a ../ (dot dot slash) in a Zip archive entry that is mishandled during extraction. This vulnerability is also known as 'Zip-Slip'.

            You can download it from GitHub.
            You can use zip4j like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the zip4j component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org.
