Starting KNIME from console: NoClassDefFoundError: Could not initialize class org.knime.database....

I already posted this question here on `StackOverflow.com`. Please check out the comments and replies for more in-depth knowledge about the problem.

All of the error messages that I could not post to the subsequent question asked on `StackOverflow.com` can be found here.

Because the operating system of my remote desktop computer that I am using for work prevents me from executing

EXE

files, I am now trying to find a workaround in order to use the software. These are the steps that I have taken so far:

I downloaded the `KNIME Analytics Platform for Windows (zip archive)` from here and unzipped it to `C:\Users\username\Downloads\knime_4.6.3`.
Then, I copied a `CMD` file, created by a colleauge, placed it in the very same folder and executed it in order to start the program. The contents of the file are as follows:

pause

After the program started, I went to `Help -> Install New Software... -> Manage...`. This opened a `Preferences` window with a tree structure set to the leaf `Install/Update -> Available Software Sites`.
I changed the URLs in the `Location` column form `https` to `http` in order to avoid having trouble with firewalls blocking traffic and clicked on `Apply and Close`.
Next, I went to `File -> Install KNIME Extensions...`.
There, I opened the node `KNIME & Extensions`, checked `KNIME JDBC Driver For Oracle Database` and clicked `Next >` twice.
After that, I selectd `I accept the terms of the license agreement` and clicked `Finish`.
When the `Software Updates` window opened, asking me the question `Restart KNIME Analytics Platform to apply the software update?`, I did not click on `Restart Now` but closed the program completely and executed the `CMD` file once again in order to start `KNIME`.
In order to create a new `KNIME` workflow, I went to the `KNIME Explorer` and right-clicked on `LOCAL (Local Workspace)` and then on `New KNIME Workflow...`.
I entered a name where it says `Name of the workflow to create:` and clicked `Finish`. This opened a new tab window in the middle of the screen with the name of my workflow.
In the `Node Repository`, I selected the node `DB -> Connection` and looked for the leaf `Oracle Connector`.
When I dragged and dropped this node onto my workspace, problems started to arise.

KNIME

first prompted these messages to its console with a lot of

ERROR DBDriverRegistry

messages and two warnings:

WARN  Oracle Connector     3:1        Please install the KNIME JDBC Driver For Oracle Database plug-in or register your own driver. For more information on how to install the plug-in see https://docs.knime.com/latest/db_extension_guide/index.html#db_plugin.
WARN  Oracle Connector     3:1        Please register a compatible driver via the KNIME preference page. (For details see the log file)

The

file contains the following (

Taking a look at

java.lang.NoClassDefFoundError: Could not initialize class org.knime.database.driver.DBDriverRegistry$DriverClassLoader

, I cannot understand why this problem arises. There is a folder called

plugins\org.knime.database_4.6.0.v202205251236

which contains a

JAR

file named

knime-db-core.jar

. Inside this

JAR

file, there is a folder path

\org\knime\database\driver

which contains a subclass file

DBDriverRegistry$DriverClassLoader.class

Why is it not found and initialised during execution?

The

CMD

file was created according to the information that can be found in the

knime.ini

file. We suppose that something with the Java classpath is still not quite right in order to make the program work properly. Or can the solution be found somewhere else? Can this problem ever be solved or is it impossible to use

KNIME

in such a way? What can be done to make

KNIME

work under such circumstances?
