This error happens because XLSReport 7.5.7 uses newer POI + XmlBeans, while your project is still loading older POI/XmlBeans jars from the userlib. The older jars are picked up first, which triggers the NoSuchMethodError.
You can fix it by:
Open the /userlib folder and identify any old POI or XmlBeans jars(e.g., xmlbeans-2.x.x.jar, poi-3.x.x.jar, poi-ooxml-3.x.x.jar, poi-ooxml-schemas-3.x.x.jar, etc.)
Do not delete them immediately — instead move them to another folder outside the project as a backup.
Make sure only the jars that come with XLSReport 7.5.7 (POI 5.x + XmlBeans 5.x) remain in userlib.
Some modules, like ExcelImporter, older CommunityCommons, or Document Template extensions, may include outdated jars, so check those as well.
After cleaning the userlib, delete the entire /deployment folder to clear cached files.
Reopen Studio Pro and run the project again.
This will resolve the POI/XmlBeans conflict, and the report generation will work normally.
