Issue

  • When we want to download a "bulk" file (.zip file) from Liferay's Documents and Media and the included content contains any special characters (e.g.: ö, ü, ä etc.), there are different issues depending on the OS we use:
    • Windows: An extra folder is added with a corrupted name
    • Linux/MacOS: Extracting the zip file fails with errors

Environment

  • DXP 7.3 below Update 8
  • DXP 7.4 below Update 32

Resolution

  • This is a known issue, resolved by LPS-148397. You can either wait for it to be released in official Updates (Update 8 for DXP 7.3 and Update 32 for DXP 7.4), or request a hotfix from Liferay Support.
  • In case of JDK 9 or a newer version: Even if you have the fix, the download won't initiate and a new blank page opens, but nothing happens.
    • To resolve that, add the following line to the configuration file, if you are using a bundle of DXP, or you can add it to your custom startup script after setting CATALINA_OPTS on your system:
       
      JDK_JAVA_OPTIONS="$JDK_JAVA_OPTIONS --add-opens=jdk.zipfs/jdk.nio.zipfs=ALL-UNNAMED"
      • After adding this to your setenv.sh, please restart the portal and check the use case again.
