拥有权限时出现权限被拒绝的错误

Question

I'm writing an excel spreadsheet file (.xls) to a directory to which I have permission, xlsOutput is a directory I made at the root of my project with full permission (right click directory>properties>resource?rwx for all three groups (owner, group, other)

however I'm getting the flowing stack trace:

java.io.FileNotFoundException: /xlsOutput (Permission denied)

Not sure why I can't write to this directory? Am I missing something obvious? I feel like I am. Any help or assistance would be much appreciated, thanks.

Edit:

@Test
public void testXMLToXLS() throws Exception {
    ITemplateGenerator tGen = new CalcTemplateGenerator();
    TestTemplate template = tGen.generateTemplate("xmlDir");
    ITemplateWriter writer = new ExcelTemplateWriter();

    String file = "/xlsOutput";
    File f = new File(file);
    logger.debug("Can write: "+f.canWrite()); // returns false but why??
    writer.write(template, file);
}

public void write ( TestTemplate template , String path ) throws Exception {

    CellFormat formatHeaders = new WritableCellFormat( new WritableFont( WritableFont.createFont("Calibri"), 12,  WritableFont.BOLD ) );
    CellFormat formatText = new WritableCellFormat( new WritableFont( WritableFont.createFont("Calibri"), 12,  WritableFont.NO_BOLD ) );

    // Create workbook object at the specified path (output directory)
    WritableWorkbook workbook = Workbook.createWorkbook( new File ( path));

    // Create a spreadhseet with name of topic and the index number at which to insert
    WritableSheet sheet = workbook.createSheet( template.getTopic(), 0) ;
    ...etc
} 

Edit:

Figured it out....

String file = "xlsOutput/testFile.xls";

I should not have included "/" in front of the directory...stupid mistake. Thanks everyone for helping

Answer 1

You supplied an absolute file system path, /xlsOutput , one beginning with a / . If you were to omit the leading `/', the JRE would interpret that as being relative to the system property user.home which would likely be the directory your project. Try that.

Answer 2

我通过添加“ /” @ immibis犯了一个愚蠢的错误，谢谢
