excel is corrupted content in web dynpro java 7.4

Hi everyone,

I used fileupload in web dynpro for java 7.4, i'm facing an issue "corrupted content" when upload an excel file to server.

resouce type: com.sap.ide.webdynpro.uielementdefinitions.Resource

My code :

try{

IPrivateMyCompView.IContextElement element = wdContext.currentContextElement();

if(element.getMyResource()!=null){

InputStream in = null;

int temp = 0;

File file = new File(wdContext.currentContextElement().getMyResource().getResourceName());

FileOutputStream out = new FileOutputStream(file);

in = element.getMyResource().read(false);

while((temp = in.read())!=-1){

out.write(temp);

}

out.flush();

out.close();

path = file.getAbsolutePath();

wdComponentAPI.getMessageManager().reportSuccess("path: "+path);

// path = usr/sap/DEP/J00/j2ee/cluster/server0/Book1.xls

try {

Workbook wb = Workbook.getWorkbook(new File(path));

} catch (BiffException e) {

wdComponentAPI.getMessageManager().reportException("BiffException: "+e.getMessage());

e.printStackTrace();

}

}

}catch (FileNotFoundException e){

wdComponentAPI.getMessageManager().reportException("FileNotFoundException: "+e.getMessage());

e.printStackTrace();

}catch (IOException e){

wdComponentAPI.getMessageManager().reportException("IOException: "+e.getMessage());

e.printStackTrace();

}

Please help me

Thanks & Best Regard,

hhoang

    Hi hhoang,

    did you compare the two files yet (the original and the uploaded one from the server)?

    Maybe you can see the difference there or the point where the "corruption" starts.

    Workbook wb = Workbook.getWorkbook(new File(path));

    create wb from stream directly, no need to save to disk....

      Hi,

      i get stream directly as below

      Workbook wb = Workbook.getWorkbook(wdContext.currentContextElement().getMy_Resource().read(false));

      it's still error, think there is something wrong when return wdContext.currentContextElement().getMy_Resource().read(false) . maybe SC of NWDS cause this issue ? I'm using SAP NetWeaver Developer Studio 7.3 SP18 PAT0002

      Thanks
