Q&A

Hello,

I am testing the new version 2021 (currently 7.3.3) and, after migrating a process, when it generates a report it gives the following error:

After installing the new version, I did not find the Jasper connector. What I did was export / import it.

Thanks

I guess you are using https://github.com/Bonitasoft-Community/bonita-connector-jasper

This connector hasn't been updated for a while and it probably cannot be used out of the box with Bonita Community 2021.1

Disclaimer: I don't know if this connector is supported nor if someone is working on it

 

The error in the logs states that the connector needs to load Apache commons-collections 1.x or 2.x classes (org/apache/commons/collections/...). Bonita now ships Apache commons-collections 4.x and related classes are in org/apache/commons/collections4 (commons-collections 3.x would be in org/apache/commons/collections3). So this is why classes are missing (if the connector doesn't provide .

Workaround to be tested: copy commons-collections 2.x jar in BONITA_INSTALLATION/server/webapps/WEB-INF/lib (path will be slightly different if you are using a Bonita Studio) and restart the Bonita server. You can retrieve the commons-collections jar from your 7.3.3 installation.

But be ready to face other issues afterwards as this connector seems out dated.

You may probably fill an issue or provide a Pull Request directly in the bonita-connector-jasper project to go any further.
