hey the error "Caused by: org.apache.poi.openxml4j.exceptions.InvalidOperationException: A part with the name '/xl/worksheets/sheet1.xml' already exists : Packages shall not contain equivalent part names and package implementers shall neither create nor recognize packages with equivalent part names. [M1.12]" due to creating xml file for that sheet with same name its happens when same sheet iterate twice so after iterate once skit next iteration.
how POI read excel is its takes each sheet and create corresponding xml file and than show xml data to us. so may be in your case it try to create same xml file twice as it previously created for same sheet. the root cause it you are iterate same sheet twice. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
