Error with SAP sapjco Java Connector

vintac — Tue, 03 Jun 2025 15:42:22 GMT

Hello,

i'm trying to read a table in SAP S/4 Hana using the tSAPTableInput component. Previsously i installed the required libraries as in the documentation https://help.qlik.com/talend/en-US/components/8.0/sap/installing-sap-java-connector-on-windows-7-64-bit-unzip
The connection to SAP is working, but when i try to run the job i get the following error. I'm using Talend studio 8 R20250521.

Exception in thread "main" java.lang.ExceptionInInitializerError: JCo initialization failed with java.lang.ExceptionInInitializerError: Illegal JCo archive "com.sap.conn.jco.sapjco.jar". It is not allowed to rename or repackage the original archive "sapjco3.jar".

I really can't manage to solve it, can anyone help me?
Thanks in advance,

Vincenzo.

Hello,

What version of sapjco3.jar do you use ?
SAP has changed in latest versions the "names" allowed for the jar file.

Using an older version of sapjco3.jar may help (for ex , the version 3.1.6 of the jar file works fine ..)

1944049 - Old release of SAP Java Connector (SAP JCo) download

Kind regards

Hello @Denis_Segard ,

is there any news about this problem? Any way to fix it?

My customer still can't use Talend with SAP, and he's getting very disappointed ...
