我用poi读excel，在window下没有问题，但把程序放到linux上时，读取客户端的excel文件报错，不知道如何解决?
错误：
C:\a.xls
You chose the file C:\a.xls.
It 's contents are: Error occurred: C:\a.xls (No such file or directory)
但在window下完全正常
我试着把c:\a.xls中的 "\ " 改为 "/ "还是不行，那位知道如何改呢，多谢
读excel的poi如下：

An example of using Jakarta POI 's HSSF package to read an excel spreadsheet:
<form name= "form1 " method= "post " action= " ">
<p> Select an Excel file to read. </p>
<p>
<input name= "xls_filename " type= "file " onChange= "form1.submit() " size= "90 ">
<input type= "submit " name= "Submit " value= "提交 ">
</p>
</form>
<%
String filename = request.getParameter( "xls_filename ");
out.println(filename);
if (filename != null && !filename.equals( " ")) {
%>
<br> You chose the file <%= filename %> .
<br> <br> It 's contents are:
<%
try
{
// create a poi workbook from the excel spreadsheet file
POIFSFileSystem fs =
new POIFSFileSystem(new FileInputStream(filename));
out.println( "fs= "+fs);
HSSFWorkbook wb = new HSSFWorkbook(fs);
for (int k = 0; k < wb.getNumberOfSheets(); k++)
{
%>
<br> <br> Sheet <%= k %> <br>
<%
HSSFSheet sheet = wb.getSheetAt(k);
int rows = sheet.getPhysicalNumberOfRows();
for (int r = 0; r < rows; r++)
{
HSSFRow row = sheet.getRow(r);
if (row != null) {
int cells = row.getPhysicalNumberOfCells();
%>
<br> <b> ROW <%=
row.getRowNum() %> </b>
<%
for (short c = 0; c < cells; c++)
{
HSSFCell cell = row.getCell(c);
if (cell != null) {
String value = null;
switch (cell.getCellType())
{
case HSSFCell.CELL_TYPE_FORMULA :
value = "FORMULA ";
break;
case HSSFCell.CELL_TYPE_NUMERIC :
value = "NUMERIC value= "

break;

linux下使用绝对路径吧。linux没有分区的。只有目录。
比如/app/soft/stat/asdfa.xls

to楼上..那poi包我下的poi-src-3.0.1-FINAL-20070705.zip怎么没有org.apache.poi.poifs.filesystem.POIFSFileSystem等文件
[解决办法]
我认为还是个路径的问题,
java代码是服务器端解析运行的,也就是在你这个linux下的,当然不能识别这种路径的
你上面说到在windows下可以,但我怀疑你是不是这样:客户端和服务器同是一台机器,这个文件表面是是客户端,但同时也是在服务器上,因为你用的同一台机器(只是这样猜测)
