os : unix & windows 2000
servlet container : tomcat 3.2.1 release For the two implementations presented below, requests submitted from the file fileupload.html call up fileUpload2.jsp twice. The file fileUpload2.jsp is called only once when fileupload.html submits a request on other serlet engines(servlet containers). Apparently this is a tomcat bug. The results are identical for UNIX and Windows 2000 systems. ΆΡ fileupload.html <form action="/examples/fileUpload2.jsp" method=post enctype=multipart/form-data> <input type=file size=50 name="upload"> <input type=reset value="cancel"><br> <input type=submit value="file transmit"> ΆΡ fileUpload2.jsp <%@ page contentType="text/html; charset=euc-kr" errorPage="error.jsp" import="java.io.*" language="java" %> <% boolean checkFileSize = true; int fileSize = request.getContentLength(); System.out.println("contentLength : " + fileSize); out.println("contentLength : " + fileSize + "<br>"); // limited file size (5MB) if ( fileSize > 1024*1024*5 ) { System.out.println("Large file size"); checkFileSize = false; out.println("<script language=JavaScript>"); out.println("alert(\"too large file. retry again...\");"); out.println("history.back();"); out.println("</script>"); out.flush(); } if ( checkFileSize ) { System.out.println("Small file size"); out.println("run file upload"); } System.out.println("end...."); %> |
