XSSFWorkbook properties

[Roberto Manicardi <ro...@gmail.com>]

Hi,

I'm new to POI and I'm trying to create a new Spreadsheet document and  
set come Core properties (such the author and the title) but I have  
some problems.

To show what I'm doing I've created a simple TestCase:

package org.apache.poi.xssf.usermodel;
import org.apache.poi.POIXMLProperties;
import junit.framework.TestCase;

public class TestXSSFProperties extends TestCase {
	
	public void testCreateWorkbookAndSetCoreProperties() throws Exception{
		XSSFWorkbook workbook = new XSSFWorkbook();
		POIXMLProperties properties = workbook.getProperties();
		
		assertNotNull(properties);
	}
}



If I run the testcase (I'm using the trunk version of POI) I have the  
following error:


java.lang.IllegalArgumentException: A document must always have core  
properties defined!
	at org.apache.poi.POIXMLProperties.<init>(POIXMLProperties.java:47)
	at org.apache.poi.POIXMLDocument.getProperties(POIXMLDocument.java:162)
	at  
org 
.apache 
.poi 
.xssf 
.usermodel 
.TestXSSFProperties 
.testCreateWorkbookAndSetCoreProperties(TestXSSFProperties.java:13)
	....


I've tried to find a way to set  the Core properties object but I  
haven't found any useful Java method.

If I create a new Workbook by loading and existing xlsx file it all  
works fine but If I create it from scratch the Core Propeties object  
is not create.

Is there a way to create the core properties or I have to patch the   
XSSFWorkbook constructor? In the second case, it's best to create the  
core properties upon creation or to add a createProperties method?


Thanks,
Roberto
