Hello,
I'm trying to use Apache POI to parse a XLS file with java.
When the file is in local I can do:
1 File file = new File("c:\\afile.xls");
2 InputStream is = file.toURL().openStream();
3 POIFSFileSystem fs = new POIFSFileSystem(is);
4 HSSFWorkbook wb = new HSSFWorkbook(fs);
without any problems.
It is working very well.
But when the file is on the web, I ave an instance of an HttpURLConnection to access it.
When I try the folloing:
1 InputStream is = httpURLCon.getUrl().openStream();
2 POIFSFileSystem fs = new POIFSFileSystem(is);
3 HSSFWorkbook wb = new HSSFWorkbook(fs);
I get a FileNotFoundException in line 3.
Does anyone knows a way to avoid this problem?
Thanks

Maybe your URL isn't correct...but we can't tell b/c we can't see that...

I think we should better verify whether the file we are going to use really exist or the path that we specify is correct by using yourFileObj.exists(). And then do things in the if statement... For instance,
