I recently added the excel importer module to a project, and configured a basic import. Unfortunately it seems that I get a missing class definition error when running it in Mendix. This error gets triggered on the "GetHeaderInformationFromExcelFile" java action, and when debugging in eclipse I get the following error: SLF4J: Failed to load class "org.slf4j.impl.StaticMDCBinder". SLF4J: Defaulting to no-operation MDCAdapter implementation. SLF4J: See http://www.slf4j.org/codes.html#no_static_mdc_binder for further details. On the following line: this.ExcelFileDocument = _ExcelFileDocument == null ? null : excelimporter.proxies.TemplateDocument.initialize(getContext(), _ExcelFileDocument); Does anyone have a solution for this issue?
I have the same error message but with another java action. It worked before but somehow I get the exact same message. I have upgraded my Java version to 18.104.22.168.
Did you ever solve the problem as mentioned above?

Oke, as a last resort I deleted .jar files that were duplicate but of another version. So I deleted the httpclient en httpcore jars with the oldest versions. And yes, it works again. So good to know to have no duplicate .jar files.
