Write Tableau Extract error

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
Message: Could not initialize class com.tableausoftware.DataExtract.Collation

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
