htmlb:fileUpload in BSP
Hi,
Iam uploading an Excel file from the local PC using the <htmlb:fileUpload>
I wanted to read this uploaded file and create a document with the data in the cells on the excel. When iam trying to read i get the data in numbers.
any ideas to read the uploaded file.
Thanks,
Shailaja
Hi Shailaja
please try CL_HTMLB_MANAGER=>GET_DATA. For BSP related question you should search in the Business Server Pages (BSP).

Maximum file size using htmlb:fileUpload
Hello Gurus,
in a bsp application we are using htmlb:fileUpload. It was possible to upload a 43 MB file without problem. But our maximum file size is about 220 MB. We made a test with a 190 MB file. After we hit the post button, the browser disconnects immediately (without timedelay) with the message: page cannot be displayed.
for me it looks like we hit some restriction.
any idears how to manage the 220 MB file in the browser beside splitting it into smaller files would be greatly appreciated.
thx a lot in advance and regards from
MichaelHello again,
could it be this parameter which is for the limitation responsible ?
icm/HTTP/max_request_size_KB = 102400

Hi Gurus,
In my custom BSP I'm using Htmlb element fileupload in the following way..
<htmlb:fileUpload id = "myFile"
accept = "true"
size = "50" />
I'm able to select only a single file when I browse for files. How should I acheive seleting multiple files ?
Thank you
SreesanthHello Sreesanth,
If you want ot upload more than one file, use <htmlb:fileUpload> that many times.

Htmlb:fileUpload = page connot be displayed
I just tried to use a this item:
<htmlb:fileUpload id="att_upload" size = "50" />
However, as soon as I instert that item into my BSP page and try to start it (F8), i get an "page connot be displayed" error in the browser. does anybody know how to use that (or another similar) item?
thxHi Daniel,
please try the following:
open your browser, click on Tool -> Internet Options
and then on the tabstrip 'Advanced'. Uncheck both entries starting with "Show friendly". Try to start your BSP again. You will get a more technical error message. This can be helpful in finding the error.

htmlb:fileupload goes into infinite loop
Hello all,
We use the tag <htmlb:fileupload> in our bsp page. Now if the user enters a file name directly, ie:without using the browse button the user simply enters a filename, say 'Resume.doc' in the input field and hits the save button on the page, then the system is going into an infinite loop and the system hangs, the users cannot proceed further and they need to restart the browser all over again(it is not necessary that the file must exist in the system, the user just types in a file name and performs the save action). This is a cause of concern for some of our customers, they expect that we should provide a meaningful message to the user and the processing should end. Is this a known issue in BSPs ?? Can anyone suggest me how to get rid of this problem ?
Thanks and Best Regards,
Viqar Ali.Hello All,
I use the following code in my bsp:
<phtmlb:matrix width="100%" >
<phtmlb:matrixCell row = "1"
col = "1" />
<phtmlb:formLayout design = "HEADING_ONLY_SOLID"
customizationKey = "<%= controller->context %>" >
<%-- Upload --%>
<phtmlb:formLayoutItem label = "<%= controller->file_label %>"
idOfItem = "upload" >
<htmlb:fileUpload id = "upload"
size = "30" />
</phtmlb:formLayoutItem>
Everything works fine if the user selects a file using the browse button to select a file. Instead if the user enters a file name directly, then the system runs into an infinite loop. I have put a breakpoint in DO_HANDLE_DATA & DO_REQUEST of the controller class. However the control doesnt come till this point also and i cannot even debug anything. The breakpoints are hit if the user selects the file using the browse button. If anyone has a similar scenario working correctly in their application pls update me with the code.
Thanks and Best Regards,

I am getting a complie error in my NWDS at the following line:
FileUpload fileUpload = (FileUpload)context.getComponentForId("fileupload");
The error is : Cannot cast from component to FileUpload.
Also, I am getting an error on the following Import statement:
import com.sapportals.htmlb.FileUpload;
The error is : The import import com.sapportals.htmlb.FileUpload conflicts with a type defined in the same file.
Any Idea why this would be happening?
Thanks
S.Bimport com.sapportals.htmlb.FileUpload;
is conflicting with the class name. Both are same.
Change the class name.

Set default file for htmlb:fileUpload ?
I use htmlb:fileUpload to let the user select a file from the file system.
Is it possible to write a start value into the textbox??
For example, I'd like to write "C:\Windows\text.txt" into the inputField when the page is first shown.<i>> I'd like to write "C:\Windows\text.txt"</i>
In short words: this is not allowed because it is not secure.
Nobody but user itself can changer something in the file upload control.
Consider the example
<fileupload default="C:\Windows\passwords.etc">

Problems with htmlb:fileUpload
Hi, I am trying to implement a JSPDynPage which uses the
fileUpload-Tag. In most cases it works fine but sometimes I can select a file but the next button click (onWork) event is not send to the server.
<hbj:form id="myForm" encodingType="multipart/form-data">
<hbj:formLayoutCell id="cf_fimport_2" align="center" valign="TOP" width="175">
<hbj:fileUpload id="upload" size="30" accept="plain/text"/>
</hbj:formLayoutCell>
and the button is defined
<hbj:formLayoutCell id="cf_fimport_5" align="right" paddingRight="7">
<hbj:button id="bpreview" text='doWork' design="STANDARD" disabled="false"
onClick="work"/>
</hbj:formLayoutCell>
The page is refreshed but no action is done.
Any idea?
Is there a bit more documentation about the fileUpload-Tag ?
Environment:
Windows XP
SAP EP6 SP4 Sneak Preview
IE 6.0
Regards
EdmundDear Edmund.
I've exactly the same problem.
In details:
Prerequisites:
1) there is <hbj:fileUpload ...> tag on the jsp.
2) The form is declared as <hbj:form id="....." encodingType="multipart/form-data">
3) There is defined button with handled event e.g. "onButtonClicked"
4) The user will insert any file to the tag
Behavior:
1) The request does NOT consist ANY components. ( I can see in the log )
2) The method "onButtonClicked" is NOT called.
3) Randomly - there is onInitialization() method called.
As it was mentioned by You, the older versions of portal works with the hbj:fileUpload correctly.
I will be very pleased with someone explaining the problem.
Regards Best
Marek
P.S.Very interesting fact: when <the hbj:fileUpload> is empty the request is sent properly - with all the components. -
Htmlb:fileUpload: change "browse" button to another language
I have a simple fileUpload Tag that shows a inputField and a "Browse" Button. In my Browser-Settings, the language is German, so instead of "Browse", there should be something in German.
Can I change that word somehow?Hi Daniel,
A very good hack has been found out for the same. Look at this weblog...
/people/dagfinn.parnas/blog/2004/08/15/inputfile-how-to-hide-the-plain-browse-button
I am sure you can find a way out from this and please let us know, your approach as well

FileUpload.bsp in BSP application SBSPEXT_HTMLB
Hi,
On the layout of this page FileUpload.bsp there is an element like this:
<htmlb:fileUpload id = "<%= %_testSuite->seq_nr( )%>"
onUpload = "HandleUpload" />
Where can I find source code of "HandleUpload"?
Thanks,Hi Pulau,
I repeat - there is sample code in the online documentation.
To quite directly from it...
If you want to read the uploaded file on the server, you do this in the
event handling phase in OnInputProcessing.
Cheers
