I tried creating the record to upload the JAR file.
steps - go to navigation bar -> type Mid server Jar file -> click on the module -> create new record -> fill the details -> click on attachment icon and upload the downloaded JAR file.
I am able to attach the JAR file like this in few of my instances but in one of the instance/environment it is keep uploading for an hour and not getting uploaded.
if anybody knows the reason let me know
