Bug ID: 60977 Summary: Adding Properties create invalid .xlsx file Product: POI Version: 3.15-FINAL Hardware: PC Status: NEW Severity: normal Priority: P2 Component: XSSF Assignee: dev@poi.apache.org Reporter: ther...@cyberrock.net Target Milestone: --- Created attachment 34909 --> https://bz.apache.org/bugzilla/attachment.cgi?id=34909&action=edit Example created file When adding a custom property, and invalid .xlsx is created. using the java code: try (final XSSFWorkbookworkbook = new XSSFWorkbook()) { final POIXMLProperties properties = workbook.getProperties(); final POIXMLProperties.CustomProperties customProperties = properties.getCustomProperties(); customProperties.addProperty("Project", project.getName()); workbook.write(outputStream); try (final java.io.FileOutputStream fs = new java.io.FileOutputStream("C:\\temp\\temp.xlsx")) { workbook.write(fs); } When you try to open temp.xlsx in Excel, you get a "file is corrupted" warning. Upon disassembling the .xlsx file, I found the following incorrect custom.xml file in docProps: <?xml version="1.0" encoding="UTF-8"?> <Properties xmlns="http://schemas.openxmlformats.org/officeDocument/2006/custom-properties" xmlns:vt="http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes"><property pid="2" fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" name="Project"><vt:lpwstr>test</vt:lpwstr></property></Properties><?xml version="1.0" encoding="UTF-8"?> <Properties xmlns="http://schemas.openxmlformats.org/officeDocument/2006/custom-properties" xmlns:vt="http://schemas.openxmlformats.org/officeDocument/2006/docPropsVTypes"><property pid="2" fmtid="{D5CDD505-2E9C-101B-9397-08002B2CF9AE}" name="Project"><vt:lpwstr>test</vt:lpwstr></property></Properties> Note the file seems to be written twice. -- 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
