Oracle Loadjava JSch Error Incorrectly Formed Java Binary Class Definition

Question

I am running into an issue trying to load a jar into Oracle. I downloaded the JSch package to code in java from source forge (https://sourceforge.net/projects/jsch/). I then attempted the loadjava command while signed into the database. I got an error and I am not sure what I can do to fix it since I am not the creator of the jar file.

Below is the output:

loadjava -user username jsch-0.1.54.jar -v                                                                                                                                  arguments: '-user' 'etl_ops' 'jsch-0.1.54.jar' '-v'

you might want to use a fork of jsch, because jsch-1.54 is pretty old. see https://github.com/mwiede/jsch — Matthias Wiedemann, May 11 '22 at 08:42
are you sure, that you want to create ssh connections triggered by a database? As an architect I would disencourage you from doing that. Use a database as a database and not as a service integration platform. — Matthias Wiedemann, May 11 '22 at 08:44

Alongside the JAR file is a zip file that contains the source code (click on the files tab and then select the version you want to download and descend into the file structure where you will find the source archive). Download the source code, compile that and make sure there are no errors and then package your compiled version into a JAR and load that.

Or else just load the source files directly into the database (but it may be easier to load a single JAR than to load multiple Java files).
