java提示OLE错误,java 读取excel 文件 Unable to recognize OLE stream 错误

使用 java 代码读取 excel 文件代码时报错如下：

jxl.read.biff.BiffException: Unable to recognize OLE stream

at jxl.read.biff.CompoundFile.(CompoundFile.java:116)

at jxl.read.biff.File.(File.java:127)

at jxl.Workbook.getWorkbook(Workbook.java:268)

at jxl.Workbook.getWorkbook(Workbook.java:253)

at test1.main(test1.java:25)

java 代码：

Workbook wb = null;

InputStream is = new FileInputStream("e://b2.xlsx");

try {

wb = Workbook.getWorkbook(is);

Sheet rs = wb.getSheet(0);

int colNum = 11;

for (int i = 0; i < rs.getRows(); i++) {

String[] nextLine = new String[colNum];

for (int j = 0; j < colNum; j++) {

nextLine[0] = rs.getCell(j, i).getContents().trim();

}

}

} catch (Exception e) {

e.printStackTrace();

}

原因：不支出读取 excel 2007 文件(*.xlsx)。只支持 excel 2003 (*.xls)。
