Exception in thread "main" java.lang.NoClassDefFoundError: routines/system/DynamicMetadata

Xavier5 — Fri, 15 Nov 2024 22:14:00 GMT

Hello,

With TOS 8.0.1 for BigData, i have a simple job for testing puprose :

tCosmosDBSQLAPIInput -----tLogRow

But the job returns errors because the Dynamic and DynamicMetaData classes are missing. The libraries must be missing.

Version 7.3.1 does not work either

How to make the tCosmosDBSQLAPIInput component work with TOS ?

Best regards,

Xavier

Hello,

Regarding of this component reference(Note part)

https://help.talend.com/r/en-US/8.0/cosmosdb/tcosmosdbsqlapiinput

To be able to use this component you would need to install a patch R2020-06

I’m afraid we do not supply patches for the Open Studio releases. We only provide patches for our subscription products.

Hello,

When you are getting No Class found error when Publishing Job in TMC issue, this is probably due to the difference between the JAVA Env where the Platform build the Job and when Published in the TMC, Could you please confirm the following?

What is Java brand and version Local studio Build Vs TMC

What is the RE Version? hosted on prem or in the cloud?

And for better understanding of the issue, could you please build the Job in Debug Mode, turn on the Run, log4j and publish the Job run it, review the log for issues concerning No Class found.

Best regards

Sabrina
