$35 Amazon Gift Certificate for first Response that solves this problem

Question

Ok, I'm ready to try bribery. I'm good for it.
          I'm on Weblogic 5.1, IE 5.5.
          I'm trying to write a simple JSP on Weblogic 5.1 to open an excel
          file. The program works fine for .pdf. But when I try to pull in an
          Excel file, the program opens excel, but the data looks like binary
          data in plain text.
          What is happening?
          Here is the code.
          String report_id = request.getParameter("report_id");
          InitialContext ctx = new InitialContext();
          DataSource ds = (DataSource) ctx.lookup("oracleDataSource");
          Connection c = ds.getConnection();
          PreparedStatement ps = c.prepareStatement("SELECT pathname, filename
          FROM report_tbl WHERE report_id = ? ");
          ps.setString(1,report_id);
          ResultSet rs = ps.executeQuery();
          rs.next();
          String filename = rs.getString("filename");
          response.setContentType("application/vnd.ms-excel");
          fname2 = "c:\\REV-SS.xls";
          File f = new File(fname2);
          byte[] b = new byte[(int) f.length()];
          FileInputStream fis = new FileInputStream(f);
          fis.read(b);
          OutputStream os = response.getOutputStream();
          

Answer 1

JSPs add blank lines ('\n' characters) ... first you need to get rid of
          those. This particular item has been discussed several times here.
          Secondly, you need to set the content type. Do this by looking for .xls in
          HKEY_CLASSES_ROOT in regedit.exe on Windows. I see that the type is
          "application/vnd.ms-excel" on mine so I assume that's what you need.
          Third make sure that the URL ends with a good XLS file name, such as:
          http://www.blah.com/blah.../GoodFileName.xls
          Now you'll fool the client into working correctly.
          Regarding the gift certificate, just donate $35 to Habitat for Humanity and
          take a tax deduction for it.
