This is either because the program required to open a file is not available on your system or there may be other issues.Jar files are compressed files which are based on the ZIP file format and used by the Java Runtime Environment (JRE).JAR files can be created to store files in a similar manner as ZIP files.
The JAR files contain several files which have been compacted into a single folder or one large file that has been compressed to achieve a practicable file size. The JAR format also supports compression which reduces the size of the file and improves download time.

All of a sudden Im not able to start the server and am getting the: error: unable to access jarfile server.jar Unfortunately this error isnt just isolated to the server.jar, Its happening with any.jar file i try to open. Just clicking on the file doesnt do anything, and even trying to open it through terminal returns that same error. I have checked the permissions of the files im trying to open, and they are all correct. When attempting to open a.jar file from terminal I have installed the latest java version. The only issue I was having was that even when I installed the java.jre file, when i tried to check the java version through terminal, it wouldnt recognise that I had java installed. I had to got the the oracle webpage and install the.jdk file in order for terminal to recognise that java was installed. Returned information when checking java version in terminal Console Output when attempting to open.jar file Worth Noting: I am on the latest macOS Big Sur Beta, however wasnt having any issues opening.jar files on Beta 3 after installation when it was released. I have created a seperate user and am having the same issues After countless hours of research and trying to figure out what is happening, I just cannot seem to figure out why macOSjava isnt opening or able to open my.jar files. Im hoping that this is the appropriate subreddit for this question, but if not, please direct me to a more appropriate one. Any help would be greatly appreciated:P MacOS Big Sur Build Information 10 comments share save hide report 100 Upvoted Log in or sign up to leave a comment log in sign up Sort by best level 1 5 points 1 month ago It looks to me as if the process does not have permissions to read from your Downloads directory.

Open Jar File Code Or SomeThanks level 1 5 points 1 month ago Its a security issue, macOS wont allow the execution of arbitrary code or some such. I checked to see if anything else was running and blocking it from opening. Thanks anyways:P level 1 2 points 1 month ago One more idea: check extended attributes and remove quarantine flag that is set on binaries downloaded from the Internet. The output did state that the jar file was in quarantine, and I was able to remove it:) View entire discussion ( 10 comments) More posts from the MacOS community Continue browsing in rMacOS rMacOS Reddits Home to Apples Latest Operating System 111k Members 415 Online Created Aug 26, 2010 Join help Reddit App Reddit coins Reddit premium Reddit gifts about careers press advertise blog Terms Content policy Privacy policy Mod policy Reddit Inc 2020.
