我将web dynpro java 7.0迁移到7.4。上传Excel文件时遇到问题。 jxl.read.biff.BiffException:无法识别OLE流Sap Portal NetWeaver 7.4:jxl.read.biff.BiffException:无法识别OLE流
我参考了一个文档“上传带有示例Web Dypro for Java的Excel文件”,但我仍然有错误。
(我使用Office 2007,以节省AAAA.xls(97-2003),并上传
file.getAbsolutePath()=的/ usr/SAP/DEP/J00/J2EE /组/ server0对/ AAAA。工作簿WB = Workbook.getWorkbook(新文件(“C:XLS)
我在项目中的Java应用程序使用jxl.jar我的桌面上试过,读取Excel文件(的* .xls)
代码时的确定: /Users/pcname/Desktop/AAAA.xls“));
但在门户网站,它抛出以下异常“无法识别OLE流”
的代码如下:
type of Va_Resource = com.sap.ide.webdynpro.uielementdefinitions.Resource
....
InputStream inpStr = null;
int temp = 0;
File file = new File(wdContext.currentContextElement()
.getVa_Resource().getResourceName().toString());
FileOutputStream opStr = new FileOutputStream(file);
if(wdContext.currentContextElement().getVa_Resource()!=null){
inpStr = wdContext.currentContextElement().getVa_Resource().read(false);
while((temp = inpStr.read())!= -1){
opStr.write(temp);
}
}
opStr.flush();
opStr.close();
path = file.getAbsolutePath();
if(path.substring(path.length()-3,path.length()).trim().equalsIgnoreCase("xls"))
{
//call method for upload
Execute_UploadOperation();
}
.....
public void Execute_UploadOperation{
try{
//path = /usr/sap/DEP/J00/j2ee/cluster/server0/AAAA.xls
Workbook wb = Workbook.getWorkbook(new File(path)); error this line, throw exception here
....
}
catch (BiffException e) {
e.getMessage() = jxl.read.biff.Biff Exception: Unable to recognize OLE stream
}
}
