tableau desktop - How to install a Denodo driver - Stack Overflow

I've installed the Tableau desktop app and I need to make a connection using the Denodo JDBC by Denodo Technologies option.

No suitable driver installed, or the URL is incorrect Connector Class: denodo_jdbc, Version: 2.0.0 Download and install the drivers, and then connect. For support, contact Denodo Technologies.

I then go to the link to download and install the drivers, and download the jar file denodo-vdp-jdbcdriver-8.0-update-20240926.jar.

So then I try to run the jar file like this:

java -jar denodo-vdp-jdbcdriver-8.0-update-20240926.jar

and I get the following error:

no main manifest attribute, in denodo-vdp-jdbcdriver-8.0-update-20240926.jar

I did some Googling, and it looks like in order to run it using the java command I need to create a META-INF/MANIFEST.MF file and include it in the jar file.

I'm kind of wondering though if I may be off on the wrong track anyway though.

Is installing a jar file the same as running it - or am I heading down a rabbit hole?

Thanks much

• Thanks - I appreciate it. I actually tried several jar files on that page as well. I always get the same no main manifest attribute error. – Tim Commented Jan 26 at 0:48
• The JAR isn't executable. I'm not sure why a manifest is required. – duffymo Commented Jan 26 at 0:56
• So I think I'm just confused over what to do with a jar file other than to 'run' it using the java -jar command. Is it another command altogether to 'install' it? – Tim Commented Jan 26 at 1:00

Follow the steps of this page: https://exchange.tableau.com/products/303

That is, move the .jar file into the following directory:

• Windows: ''C:\Program Files\Tableau\Drivers''
• macOS: ''/Users/[user]/Library/Tableau/Drivers''

Relaunch Tableau and connect using the Denodo JDBC connector.

A JAR can either be executable or used as a dynamic link library that's loaded by the JVM at runtime. The JDBC driver JAR is an example of the latter.

No, you don't run the JDBC JAR in this case. You have to package it with your application that accesses Tableau. You need to add that JAR to the application CLASSPATH or package it with your client app.

How do you tell Tableau where to find the JAR and how to configure it? Consult your Tableau docs.
