Bug ID: 66675 Summary: Save not happening in work book showing A part with the name '/docProps/core.xml' already exists Product: POI Version: 5.2.3-FINAL Hardware: PC Status: NEW Severity: blocker Priority: P2 Component: XSSF Assignee: dev@poi.apache.org Reporter: prabhu...@gmail.com Target Milestone: --- Created attachment 38595 --> https://bz.apache.org/bugzilla/attachment.cgi?id=38595&action=edit This attachment shows the error Hi I am using apche poi ooxm-5.2.3 version and i was tried older version also. I have used apache poi for reading the xlsx sheets and removing the selected tabs that is working fine after deletion the save not happen it throwing the following error. org.apache.poi.openxml4j.exceptions.InvalidOperationException: A part with the name '/docProps/core.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] at org.apache.poi.openxml4j.opc.OPCPackage.addPackagePart(OPCPackage.java:947) at org.apache.poi.openxml4j.opc.ZipPackage.saveImpl(ZipPackage.java:547) at org.apache.poi.openxml4j.opc.OPCPackage.save(OPCPackage.java:1496) at org.apache.poi.ooxml.POIXMLDocument.write(POIXMLDocument.java:227) at com.simplilearn.mavenexample.Authentication.getWorkbook(Authentication.java:691) at com.simplilearn.mavenexample.Authentication.exportToFile(Authentication.java:656) at com.simplilearn.mavenexample.App.main(App.java:29) So as per my understanding whenever edit happens using the apche poi it try to create new OPC package part checks existing part so that time the error displayed. For testing purpose i have deleted the package part then it was allowed for SAVE. The JAVA code is pretty straight forward. try { ByteArrayOutputStream bos = new ByteArrayOutputStream(); XSSFWorkbook testWorkBook = new XSSFWorkbook(inputfile); testWorkBook.removeSheetAt(0); testWorkBook.write(bos); } catch(Exception e) { e.printStackTrace(); } Observations: 1.Once opened XLSX even without change also not allowed for save 2.The part name removal working only for windows Environment not LINUX server -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
