Hi,

after upgrading to RM 7.2 I'm trying to use the Tableau Data Writer but it fails every time with this stack trace

Exception: java.lang.NoClassDefFoundError

I've downloaded the Tableau Extract API (64 bit, same as RM) and extracted it to disk. I've also added the \bin to my PATH so it should be working but does not.

Hello @bobpeers

 

Can you check if you had the Tableau API downloaded from here http://www.tableau.com/data-extract-api

and not the new Tableau SDK

Hi,

 

I downloaded and indstalled the Tableau Data Extract API from the Tableau website and added the path to the bin folder to my path as shown in the images. I get the error shown in the screenshot.

 

thanks,

Re: Write Tableau Extract error

Hi,

 

I have fixed this issue myself. It's because you can add the path to the \bin folder in either user or system environment PATHs, you must add it to the system PATH as adding only to the user PATH does not work. I think the documentation should be updated to point this out.

 

best regards,

Bob

Re: Write Tableau Extract error

I also cannot get Tableau Writer to work after following instructions exactly. Says there are missing Tableau DLLs

Re: Write Tableau Extract error

Done, thank you.

But still weird to know that cannot use Tableau SDK instead of Data Extract API, as i know, Data Extract API was duplicate to Tableau SDK.
