Does the excel file get parsed correctly without the HTTP Transmission?
I'm not sure you need to the safe stream anymore, the heavy lifters (thanks guys!) patched it to accept slow streams.

Can you also provide a more detailed stack trace so we can guess a little better?

To all;
I get ExceptionInInitializerError at HSSFWorkbook.
I'm using poi...20040804.jar, and JRE1.4.2_04.
The URL generated "HTTP://www....../.../barry/images/excel.xls";
is correct. Printing the header field shows "HTTP 1.1 200 ok",
more messages, then "application/msexcel", date twice
then the length of the file. Everything I read points to
a compatibility issue.
Any thoughts.

HSSFWorkbook Read1() throws IOException { URL url = new URL(codeBase, "barry/Images/Excel.xls"); URLConnection uc = url.openConnection(); String field = uc.getHeaderField(0); for (int i=0;field != null; i++) { JOptionPane.showMessageDialog(null, field); field = uc.getHeaderField(i); } SafePOIStream is = new SafePOIStream(uc.getInputStream()); HSSFWorkbook wb = new HSSFWorkbook(is); return wb; }
