In IE 6 File download frm Webdynpro generates RandomName whn download in EP

Hi Experts,
I have developed a webdynpro application where I download a file in the excel format.
I have written a code to generate the name of the file and have set it to the context attribute.
When I download the file from the Application
http://<server>:<port>/webdynpro/dispatcher/local/<project>/<application>
The name (test.xls) of the downloaded file is perfect
but when downloaded from the Jave webdynpro Portal Iview we get random names like "CAIF4T6T.xls" in the Dialog which stores the file on the local system.
Is there anything which needs to be done in Iview properties so that when downloaded into local machine we get the same name as we get during the download from the application directly.
It is working fine in Internet Explorer 7 But lower version not supported

Krishna

Java WebDynpro's and IE security settings for file download

We have a EP 7.0 SP13 environment on which we have deployed a number of own developed java webdynpro's. In some of these webdynpro's we provide the file download functionality. The portal and webdynpro's are used by both internal personnel and external customers.
On the other hand the default Internet security settings for Internet Explorer, disable "Automatic prompting for file downloads".
When a user, with these default security settings active, tries to use our webdynpro's file download functionality, the screen seems to refreshes but no file download starts. When (s)he retries, the session runs for some minutes and gives following error message:
"com.sap.tc.webdynpro.services.session.LockException: Thread SAPEngine_Application_Thread[impl:3]_20 failed to acquire exclusive lock on client session ClientSession".
This behavior is explained in SAPNote 1234847. Webdynpro provides a single-thread module, meaning a user session is blocked for the during of the request. And because the previous file download isn't yet completed the new try can't start.
Issue now, although the users IE settings allow file downloads and don't block pop up's, he can't download the file and even isn't made aware of the cause of the failure.
How can we avoid this issue, without having to communicate the
application requires specific browser settings?

And i use the same code in other event , it works fine.
Please help me.
Regards,
Sandeep.

Hello Sandeep,
Probably someone will help you if you paste here part of the source code.
The issue could be due to different reasons, for example the one described here:
[Note 1428974 - file name is garbled while downloading resource using IE6|https://service.sap.com/sap/support/notes/1428974]

TAx Reporter Temse Files Download Automation

Hi,
I have a reuiqrement to download the Temse files generated in Tax Reporter. I have completed the code and it works fine if we run the program in foreground. But when I run the same program in background some Temse files downloaded have junk characters. If I download the same Temse file in foreground it works fine.
There seems to be some issue with the FM when I run my progam in background.
I have searched SDN and SAP Notes for any clues but did not get any.

Can anyone please check and tell me what I need to overcome this problem.

Hi Bhaskar,
I also have the same requirement to upload TemSe files in to application server.
In FDTA tcode after we enter company code and click on enter.
In the second screen checking and line item and go to edit and click on download button.
Here we see a popup with default file name, and when we say ok the file will get downloaded into C:\.....
Here our req is to upload the file automatically pick up via batch job and place it in the in to the application server and from there it should be placed in the Netwrok server (UNIX).
Pls provide me with suitable code so that i can finish it off.I tried a lot but did not work.
Thanks.

Can not open file download prompt in portal web app.

Hi folks,
I am migrating existing Struts app into portal web app and currently stuck on the following problem.
In existing app, Struts action calls servlet that generates excel file, sets response headers:
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-Disposition","attachment;filename=thename.csv");
that brings up "file download" prompt window.
In portal app, the same code writes excel file content into browser window instead of the prompt.
Has anyone had to deal with similar problem? Any help will be greatly appreciated.
Alex.
Version of portal used is 8.1 SP5
Struts - 1.1

Problem is resolved. For those who might be interested - specifying redirect=true on forward to servlet did the trick.

File download problem

I am using the following code to present a file to the client to download when a report is generated. The code does what is suppose to, it presents a dialog box where the user can choose to open, save, or cancel the file download. However, when the file is downloaded it contains the client HTML at the bottom of the saved file. I checked the created file on the server and it does not contain the HTML at the bottom, so it is being added by the following jsp code when the file is presented to the user. Any help would be appreciated. BTW, this running on HP-UX 11i using oracle forms 10G.
   String RPT = request.getParameter("trig");
   String SDATE = request.getParameter("start_date");
   String EDATE = request.getParameter("end_date");
   String PRN = request.getParameter("prn");
if(RPT != null)
     try {
          Runtime rt1;
          Process proc1;
          String[] doRefresh = {"/usr/bin/sh", "-c", "/usr/local/oracle/sql/st_tags/some_script '" + SDATE + "' '" + EDATE + "' '" + PRN + "'"};
          rt1 = Runtime.getRuntime();

JSF error message: Automatic prompting for file download

This is a weird problem. I have a JSF application wherin I popup a new window on a submit button.
The window opens a test.jsf page that redirects the output to a servlet1.
Servlet then based on some parameters does a sendRedirectI() to different servlets out of context.
Now the issue is that when the output is redirected to out of context servlet, that returns a file download.
If in IE browser, if one does not do a setting of "Automatic prompting for file download", this window that I had opened on submit buttton vanishes in a jiffy. If the IE setting is done, it shows the file download correctly.
I would want to show the user some kind of message by which he/she understands that this IE setting has to be done.
I have tried several ways:
1. Javascript: window.onbeforeunload on the test.jsf so that when the window unloads i can show some message. But since test.jsf forwards to servlet1, the html page generated does not show my script.
2. I also tried checking if some windows registry can help me understand the setting.
3. I tried writing in response object the javascript and then redirecting it to servlet out of context. But I guess sendRedirect() does a new request, so this did not help.
Can anyone help? I am not sure if I am able to explain my problem correctly.
Yani

Here is the result.I used your code and it worked fine with IE setting Enabled. But when I tried to access the download servlet after opening a new window, it doesnt download the file.

Unwanted File Download box in JSF - Problem while Saving State.

Hi,
I am having a situation wherin there are multiple command links dynamically generated in a dataTable.When I click on any one of the links a file download dialogue pops up to save/open a pdf doc.Irrespective of any operations on the download dialogue, if I click on anyother link (i.e this is the 2nd click on tat page)
then the file download doesnt pop up and instead the page is refreshed.
On the 3rd click , the file download again pops up.
The code in the action method of the command link goes like this
public void showPDF() {
byte[] pdf = // gets the data from another place.
FacesContext faces = FacesContext.getCurrentInstance();
          HttpServletResponse response = (HttpServletResponse) faces.getExternalContext().getResponse();
          response.setContentType("application/pdf");
          response.setContentLength(pdf.length);
          response.setHeader("Content-disposition", "attachment");
          response.setHeader("Cache-Control", "cache, must-revalidate");
          response.setHeader("Pragma", "public");
          try {
               ServletOutputStream output = response.getOutputStream();
               output.write(pdf);
          } catch (IOException e) {
                    log.debug("IOException in viewPdf: " + e.toString());
     faces.responseComplete();
}To fix the above problem ...I have included the following 2 lines of code just before invoking the responseComplete() method :
StateManager stateManager = (StateManager)
                                                                faces.getApplication().getStateManager();
     stateManager.saveSerializedView(faces);This solves the above problem but causes another problem for which I need help :
There is a value change listener in my jsp.When I change the value in a drop down list in the same page, the file download dialogue is poping up. which shuld only pop up when am clicking any one of the command links.
I debugged thru the code and found out that after the value change listener action method is finished executing it jumps and executes the above showPDF() method.
Seems its something to do with saving of the client state.
It will be of great help anyone can advise on this.
Thanks

XML file download to presentation server.

Hi Experts,
Here I have a question regarding file download to desktop.
I have a report which will generate xml file. Once it is generated i would like to download to desktop.
I tried with 'GUI_DOWNLOAD', but it is not working. It means the file is downlaoded to presentation server but when i opened it 'Page can't be displayed' message is comming.
Could you pleas help me to solve this issue.
Thanks in advance.
Regards,
Anil.G

Hello,
For processing XMLs always try to make use of the class CL_XML_DOCUMENT.
You can download the XML stream to a local file using the method of EXPORT_TO_FILE class CL_XML_DOCUMENT.

File Download box appears despite content being text/html .....

Hi
I am supporting a set of web pages which display data to the user based on XML transformed by a set of style sheets. Currently when the user does something and fires the doPost method we get the "File Download" box appear with the message "Some files can harm your computer .................... ". The downloaded file is just the HTML used to display info to the user (with the appropriate embedded stuff from the stylesheet)
I was under the impression that this dialogue box only appears when the content type is not understood by the browser. However, the content type is text/html ... so i am a bit stumped.
can anyone suggest other ways in which this message can appear?
cheers
chris

Just on the off chance anyone else ever has this problem and fins this post ( the problem was solved a long time and i forgot to update the post).
The application in question attempts to log into a database via OC4J. The connection information in the data-sources.xml file was incorrect (specifically the database listener port). This was generating some bizarre exception which was propogated up and resulted in the above behaviour. I suspect that you could get the same effect thogh for many other reasons, so if you are having this problem i wouldnt get too hung up on this as a possible cause,.

How to check the status of file downloading?

I have to download the selected file by using "file download" dialogue box.
This "File Download" dialogue box provides options for "Open", "Save", "Cancel" or "More Info". It is similar to usual "File Downloading".
And i am required to do further processing only if , file is "Open" or "Save".
So how can i check the status of the option selected by the user?
Following is the code snippet:
res.setContentType("text/plain");
res.addHeader("Content-Disposition", "attachment; filename=" +value);
try
     uFile= new File(fPath);
     fSize=(int)uFile.length();
     fis = new FileInputStream(uFile);
     c=-1;
     while ((c = fis.read()) != -1)
          out.print((char)c);
     fis.close();
     out.flush();
     out=null;
catch(Exception e)
       out.println("Exception : " +e);
} I tried to generate a flag and inside a while loop, and then checking the status of that flag outside of loop.
But it doesn't work.
It reflects the value of flag even if user selects "Cancel" Option.
So, if there is any another way of checking the option selected by user from "Open","Save" or" Cancel", then please reply me.
Thanks in advance.

Is there any solution for this or any web link for this...?
Thanks in advance,
Waiting for reply

Typical Problem !! File Download UI related

Dear All,
I'm stuck in a typical problem. I upload files thru the File Upload UI and generate uique IDs against every upload document.
For displaying the documents, the user goes thru a web page that has URL to a WDA application.
This WDA application has the unique Number as application paramater.
The problem : If the default view of the WDA has a button and on click the uploaded file opens properly. But if I write the same code in WDINIT , the code gets executed but doesn't open the uploaded file. Reason??? I fail to understand !!!
Any help would be highly appreciated.
Regds,
Srini

Are you using the attach file to response API? Basically in the WDDOINIT, the page is being built for the first time. Therefore the framework on the client side isn't rendered yet to be able to download a file. If you want a file download to trigger "automatically" upon a page load; consider using a timedTrigger UI element set to 1 second and then download the content upon the event of the timedTrigger.
Is this WDA only being used to download the files via a Link? If so consider if you really need WDA for this. That's a heavy weight framework if you are only wanting to push the download of a file. A stateless BSP or even a ICF handler class might be much better options.

ZIP File has damaged contents - Multiple file download

Hi,
I am using ZIP API in Web Dynpro JAVA for multiple file download scenario.
Issue:--->
Some files are not opening correctly after unzipping the ZIP file.
Example-1: some PDF files gives out message that " "
Example-2: Also, a JPG file shows only upper half of the image.
So in all, the content of generated ZIP file are damaged.
Any idea why this is happening?
Thanks & regards,
Amey

And this is the code I'm using:-
Unzipped PDF files give this error --> There was an error opening this document. The file is damaged and could not be repaired
for(int i = 0; i < l_int_NodeSize; i++){
     g_SearchOutputEle = g_SearchOutputNode.getCtx_vn_SearchOutputElementAt(i);
     java.net.URL url = new URL(g_SearchOutputEle.getFileUrl());
     java.net.URLConnection urlConnection = url.openConnection();
     java.io.InputStream inputStream = url.openStream();
     int arraySize = urlConnection.getContentLength();
     byte[] byteArray = new byte[arraySize];
     DataInputStream dis = new DataInputStream(inputStream);
     dis.read(byteArray);
     ZipEntry zipEntry = new ZipEntry("Name-"+i);
     zipEntry.setSize(byteArray.length);
     zos.putNextEntry(zipEntry);
     zos.write(byteArray);
     zos.closeEntry();
zos.close();
byte[] byteOutArray = baos.toByteArray();
IWDResource resource = WDResourceFactory.createResource(byteOutArray, "Downloads.zip",WDWebResourceType.UNKNOWN);
String urlString = resource.getUrl(WDFileDownloadBehaviour.ALLOW_SAVE.ordinal());
IWDWindow win_MultiFileWindow = wdComponentAPI.getWindowManager().createNonModalExternalWindow(urlString);
win_MultiFileWindow.setWindowSize(0,0);
win_MultiFileWindow.show();
