Talend Studio: tQVDOutput mixed mode error

stecava82 — Tue, 02 Sep 2025 16:41:01 GMT

Hi everyone,
I’m testing the tQVDOutput component with Mode = mixed on version R2025-08, but I'm getting the following error:

Exception in component tQVDOutput_1 (qvd)
org.talend.sdk.component.api.exception.ComponentException: (java.sql.SQLException) No suitable driver found for jdbc:h2:file:/tmp/testdb_4c3354c0-479d-4c9f-91c8-7fe48fdcf2d0;DB_CLOSE_DELAY=-1

Does anyone know what might be causing this or how to fix it?

Thanks in advance!

Hello,

Using procmon ( https://learn.microsoft.com/en-us/sysinternals/downloads/procmon ) to trace the file operations done by the Job Java process , we can see a file *.mv.db is created and the java process is reading the JDBC h2 driver h2-2.3.232.jar :

Did you try to set the log4jLevel to TRACE to check if some messages could help ?

Kind regards
Denis

Hello,,

... and check in the Modules view if h2-2.3.232.jar is installed :
