I indicated the wrong builder method previously. I use the
'open(java.lang.String path, PackageAccess access)' method. This is the only
open method which contains an option to control the package access method.
In the first code example below, if you uncomment the .revert() line, the
delete works. When it is commented the file will not be deleted.
In the second code example I changed the code to use a buffered input stream
rather than the String and package access options. The second option works as
is.
Code #1:
import java.io.File;
import java.io.IOException;
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.openxml4j.opc.OPCPackage;
import org.apache.poi.openxml4j.opc.PackageAccess;
public class OPCError
{
public static void main (String args[]) throws InvalidFormatException,
IOException
{
File fileToProcess = new File("F:\\temp\\opcerror.xlsx");
OPCPackage xlsxPackage =
OPCPackage.open(fileToProcess.getAbsolutePath(), PackageAccess.READ);
xlsxPackage.close();
// xlsxPackage.revert();
if (fileToProcess.delete())
System.out.println("Deleted");
else
System.out.println("Not deleted");
}
}
-------------------------------------------------------------------------------------------
Code #2
import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.openxml4j.opc.OPCPackage;
public class OPCError
{
public static void main (String args[]) throws InvalidFormatException,
IOException
{
File fileToProcess = new File("F:\\temp\\opcerror.xlsx");
InputStream bis = new BufferedInputStream(new
FileInputStream(fileToProcess));
OPCPackage xlsxPackage = OPCPackage.open(bis);
xlsxPackage.close();
// xlsxPackage.revert();
if (fileToProcess.delete())
System.out.println("Deleted");
else
System.out.println("Not deleted");
}
}

close should call closeImpl if it was opened from a file, which ought to
close down the input source too
Are you creating your opcpackage from an InputStream or a File?
