Regarding the validations in File Upload.

Hi
I am Using the X:InputFileUpload> for uploading of the my file and i am using validator class for checking the validation like if the file name is null. But i need one more validation to check the file format like if i have enter any special characters and invalid file format(SSS) i want give a message to the user.
Please suggest me how can i approach using Myfaces.
Thanks in advance.
Regards
Satish

I have never used myfaces implementation but I am sure you can just define your own custom validator and attach it to this component or assign a method binding to its validator attribute to perform extra validation.

Unable to get the filename from file upload UI element

Hi,
I added a FileUpload UI element.
I created an attribute of type resource , assigned to the resource property of the file upload element.
I created an action button called upload and added the following code.
try {
       IWDResource resource = wdContext.currentContextElement().getFileupload();
      } catch (Exception e) {
         e.printStackTrace();
when I debug to see the value of resource it is null.
Please let me know where I am going wrong.

Hi,
Check if there are any space characters in your uploading path (file path).
First try to upload a file without any space characters in the uploading path(file path). If the problem is with the space characters then use the below encoding & decoding to resolve that issue.
Encoding while uploading the file:
// Getting the file resource
IWDResource resource = element.getCtx_va_FileResource();
//Getting the resource name
String resourceName = resource.getResourceName();
//Encoding the resource name
String encoderesourceName = java.net.URLEncoder.encode(resourceName,"UTF-8");
Again while downloading you can use decoder.
Hope this helps to resolve your issue.
See this below link.
Re: File Upload Problem
Try this encoding even if there are no space characters.

Validator for file upload component is not working !!

This validator method for a file upload component is throwing a java.lang.NullPointerException.
public void fileUpload1_validate(FacesContext context, UIComponent component, Object value) {
long size= fileUpload1.getUploadedFile().getSize();
if (size>65535){
throw new ValidatorException(new FacesMessage("Your image is too big!"));
Any help to solve this problem is very much appreciated.
Thanks.

Hi i have a fileUpload in a pop-up and the methods are :
public void fileUpload1_validate(FacesContext context, UIComponent component, Object value) {
try {
com.sun.rave.web.ui.model.UploadedFile uploadedFile = ((Upload)component).getUploadedFile();
long l_filesize = uploadedFile.getSize();
if ( l_filesize > 1000000)
throw new ValidatorException(new FacesMessage("File Size should be less than 1000000 bytes! It is" + l_filesize));
else {
String tipo = uploadedFile.getContentType();
if ( tipo.compareTo("application/word") == -1 )
if ( tipo.compareTo("application/rtf") == -1 )
if ( tipo.compareTo("application/pdf") == -1 )
throw new ValidatorException(new FacesMessage("Error : los tipos de archivo aceptados son PDF, WORD y RTF"));
} catch (Exception ex) {
this.mauvaisFichier = true;
error(ex.getMessage());
public String botonValidar_action() {
if ( !this.mauvaisFichier )
if ( this.fileUpload1.getUploadedFile() != null )
if ( this.fileUpload1.getUploadedFile().getSize() > 0 )
try {
this.getSessionBean1().getComunicacion().setArchivo( new javax.sql.rowset.serial.SerialBlob(this.fileUpload1.getUploadedFile().getBytes() ) );
this.getSessionBean1().getComunicacion().setTipoArchivo( this.fileUpload1.getUploadedFile().getOriginalName().substring(this.fileUpload1.getUploadedFile().getOriginalName().length() - 3 ) );
} catch(Exception e){
e.getMessage();
return null;
I have to put a boolean value because the first time, validation code doesn't function ( the method botonValidar_action() is called ) correctly. The error message appears but empty.
If I try next time then it's ok.
Thx for any issue.

Failed validation of file uploads makes them uneditable

I have an issue with a file upload field (af:inputFile), such that if an error occurs on submission the error message is not modal and so the user can altar the values and reenable the OK button with an error message still visible.
I was attempting to get around this since noone seemed to have a way to make the faces error messages modal (Is it possible to make message popup with error messages modal?).
I tried putting in a validator for the file... which works just fine (once you manage to actually clear the thing on cancel)... apart from the fact that once the validation fails the file name is shown as read only with an update button instead of a browse button. That update button then opens another dialog with a file upload in it and no matter what you do in this dialog the original one remains unchanged... and can be made visible if you move the new dialog off the top of it.
Why can I not actually update the file? Why does it open a different dialog with a different input field that doesn't have my validator or binding or value? What can I do to get around this?
I'm in ADF 11.1.1 but can use 12.1.2 if absolutely necessary for a fix. I don't use JDeveloper.
Thank you.

Thank you! Calling resetValue() on the file input component in the validator just before throwing ValidationException does the job!
I've added the filename to my validation error message so that the user can still see which file it was they tried to upload and I think that solves all my issues

Question regarding the itunes library files when moving itunes library from 1 hard drive to another.

My itunes library had out grown my 2TB drive (I'm a bit of a podcast addict) so I got a 4TB drive to replace it but for some reason my Mac Pro started to act up and eventually apps became crippled to where they would not open.
So I had no choice but to go back to my 2TB drive for my boot drive for now but my itunes library is now slightly larger than the 2TB drive and won't fit so with my previous 4TB drive connected via a hard drive dock I followed the instructions to move my itunes library to a secondary 4TB drive in my mac pro and that went fine the one thing I noticed is in the article it says not to move the 2 library files but now my itunes media is on a internal drive and the 2 library files are on the hard drive connected to my mac pro via the dock so if I was to remove the drive from the dock the 2 library files would no longer be accessable and my itunes library would not be able to be found even though the media in on one of my internal drives.
Anyone know how I can rectify this issue?

Basic doubts Regarding the RFC to File scenario.

Hi All,
I'm doing a RFC to File scenario, so before starting the development i went through many blogs and sites to know more the about scenario. I'm confused in the step where we have to create a RFC (type TCP/IP) in sm59.
I have the following doubts :
1)whether to create the RFC in sender (which will be ECC system) or XI.
i.e., RFC in sender (ECC) pointing to xi system in sm59 of Sender(ECC)
or
in XI pointing to sender (ECC) system.
2) the program id maintained in RFC.
the program id is any name or the FM which is being imported in XI system.
Thanks in Advance,
Kind Regards,
Lalitkumar.

Hi Lalitkumar,
1)whether to create the RFC in sender (which will be ECC system) or XI.
i.e., RFC in sender (ECC) pointing to xi system in sm59 of Sender(ECC)
or
in XI pointing to sender (ECC) system.
It should be in sender ECC.
2) the program id maintained in RFC.
the program id is any name or the FM which is being imported in XI system.
It can be any name but should be same in RFC destination and RFC adapter.
As stefen mentioned use ABAP proxy inspite of RFC as its better performance wise.

BPS Flat File Upload Error Messages

Hi,
I am using the BPS flat file upload and am getting error messages. These error messages are coming from the user exit in the characteristics relationships. Unfortunately the message does not indicate which line on the upload file the error is for. In the user exit it does not pass the line no of the flat file that is being processed.
Does anyone have any ideas how the message could be enhanced to indicate the line in error or if there is another exit I could perform the validation in?
regards
Paul Cairncross

Hi Sai,
The issue is not the particular message. The message is in fact my message in the user exit in the characteristic relationships. The issue is when using the flat file upload the message does not indicate which line in the file the message apply's to. Looking at the userexit no line number is passed. This is not a problem in the web as the specific line is highlighted when the user is keying in the data.

Calendar & File Upload Components - Threadinar6

Hi All,
This is the sixth in the "Threadinar" series , please see Threadinar5 at
http://swforum.sun.com/jive/thread.jspa?threadID=99473 for details
In this Threadinar we will focus on the
"Calendar" and "File Upload" Components
Let us begin our discussion with the Calendar Component.
Calendar Component
You can drag the Calendar component "calendar component icon" from the Palette's Basic category to a page open in the Visual Designer to create an entry field with an integrated calendar pop-up to help the user pick dates for the field.
You can also drop the calendar on a container component, like a table cell or group box.
After dragging the component to the Visual Designer, you can work with the following useful properties of the Calendar Component:-
General
* id. Type: String
The name of the Calendar component in the page bean and the JSP file.
Appearance
* columns. Type: int
The number of character columns used to render the component. The default value is 20.
* dateFormatPattern. Type: String
The format of the date to be entered by the user. It is not usually necessary to set this property because a pattern is chosen automatically based on the locale.
If you prefer to specify a date format, click the ellipsis button (...) to the right of the property and select a predefined date format from the property editor's list. You can also add your own formats. If you add a format, the values you can enter are limited to some combination of yyyy for the year, MM for the month, and dd for the day separated by separator characters. Typical separator characters are / (slash), . (period), and - (dash). For example, the following date formats are acceptable:
o MM/dd/yyyy
o yyyy.MM.dd
o MM-dd-yyyy
* dateFormatPatternHelp. Type: text
Text that appears below the date entry field and shows the format pattern that the date entry field accepts. If you have not set the dateFormatPattern property, the help text is chosen automatically for you. If you have set the dateFormatPattern property, you should bind the dateFormatPatternHelp property to a localized string that matches the setting for each locale you want to support.
* label. Type: String
A label that appears next to the text entry field, typically describing what the user is supposed to enter.
o Note: The label property is not as flexible as the Label component. You can use the Label component if you want more control over the label's appearance, such as positioning of the label relative to the component.
* labelLevel. Type: int
A number that affects the appearance of the label. 1 (Strong) is larger and bold. 2 (Medium), the default, is smaller and bold. 3 (Weak) is smaller and normal (not bold). This property takes effect only if the label property is set.
* style. Type: String
Cascading Style Sheet rules (CSS level 2) to be applied to the component. For example:
position: absolute; left: 288px; top: 312px
You can enter values directly or click the ellipsis (...) button to use the Style Editor.
o Note: This property overrides any settings in the theme or the project CSS file for this component. If a style specified in this property does not appear to take effect, it is because an area of the component is obscured by a child component that has different style settings.
For a list of CSS2 style attributes, see the web page at
http://www.w3.org/TR/REC-CSS2/propidx.html
* styleClass. Type: String
A space-separated list of CSS2 style classes to be applied when the component is rendered. The style classes must be defined in the project's style sheet or in the theme's CSS file. If you click the ellipsis button (...), you see a list of all styles you can add to this property. For information on adding CSS classes and rules to the project's cascading style sheet, see CSS Editor.
o Note: See the note above under the style property description for an explanation of why a class added to this property might appear to have no effect on the component.
o Note: If you add a CSS style class from the current theme to your project CSS file and you redefine the style class, the change affects all components that use this style class. However, you can add your own style classes to the project CSS file that redefine the default style classes, and then when you add them to this property, the changes affect only this instance of this component.
For the defaulttheme.jar CSS style classes for this component, see Calendar Component CSS Classes.
Data
* maxDate. Type: java.util.Date
The last date that the user can select. The default value is four years from the date set in the minDate property, for a total span of five years.
* minDate. Type: java.util.Date
The earliest date that the user can select. The default value is the value of the selectedDate property, which defaults to the current date if that property is not set.
* required. Type: boolean
If selected, the user must enter a value for the calendar before the page can be submitted. If you add a Message component to the page and link its for property to this component, an error message will be displayed if the user tries to submit the page without entering a value.
* selectedDate. Type: Date
A java.util.Date object representing the calendar date selected by the user. If you right-click the component and choose Bind to Data, you can bind this property to a data provider or object that can process the user entered value on the server.
When the component displays initially, if this property is not set, its value defaults to the current date. If you provide values for minDate and maxDate, you can also provide a value for this property that initially displays a date in that range.
* validator. Type: MethodBinding
Indicates the JavaServer Faces validator that is called when the value is submitted. A validator ensures that the correct value is entered by a user. Choose a validator from the drop-down list. If you choose (null), no validator is called. If you choose a validator, also select the required property to ensure that the validator is used. For descriptions of JavaServer Faces validators, see the list of topics at List of Validators.
o Note: If you define your own validate method, for example, by right-clicking the component and choosing Edit Event Handler > validate, any value you might have set in this property is overridden.
File Upload Component
You can drag the File Upload component "file upload component icon" from the Palette's Basic category to the Visual Designer to create an entry field and a browse button that opens a file chooser dialog on the local system, enabling the user either to select a file or to type a file name into the entry field. When the page is submitted, a copy of the file's contents is sent to the web application.
The component is similar to an HTML <input type="file"> element.
* Note: This component is neither supported by nor available in portlet projects due to security reasons.
* Note: The size of the component in the Visual Designer might not match the size of the component when it is rendered in a web browser, making the component appear to line up correctly in the Visual Designer, but not when the page is rendered in the user's web browser. Also, the rendering of this component can differ depending on the web browser. Be sure to test the component in the web browsers that you expect your users to use. For example, if you add a width setting to the style property that is smaller than the setting in the columns property, Internet Explorer observes only the width setting, while the Mozilla browser ignores it and sets the width according to the number of characters in the columns property.
The File upload component uses a filter, a com.sun.rave.web.ui.util.UploadFilter object that is configured for you in the web application's deployment descriptor. The UploadFilter uses the Apache commons fileupload package. You might need to change these settings in the following two cases:
* The server holds the uploaded file in memory unless it exceeds 4096 bytes; otherwise, the server holds the file contents in a temporary file. You can change this threshold by modifying the sizeThreshold parameter for the UploadFilter filter entry in the web application's web.xml file.
* By default, the File Upload component can handle files up to one megabyte in size. You can change the maximum file size by modifying the maxSize parameter for the UploadFilter filter entry in the application's web.xml file.
o
A negative value for the maxSize parameter indicates that there is no file size limit. Setting the parameter to a negative value is not recommended for security reasons. For example, if you allow unlimited file sizes, a malicious user could mount a denial of service attack on your site by using extremely large files
* To change the settings for the UploadFilter object in the web.xml file:
1. In the Files window, expand project-name > web > WEB-INF.
2. Double-click the web.xml node to open the file in the XML editor.
3. Click the Filters toolbar button.
4. In the UploadFilter section under Initialization Parameters, you can change the values for the maxSize and sizeThreshold parameters.
The contents of the uploaded file, together with some information about it, are stored in an instance of com.sun.rave.web.ui.model.UploadedFile. By using this object, you can get the content of the file as a String or write the contents to disk, as well as get properties such as the name and the size of the file. In the interest of conserving memory, the contents and file data are only available during the HTTP request in which the file was uploaded. To access the contents of the uploaded file, bind the uploadedFile property to a bean property of type com.sun.rave.web.ui.model.UploadedFile. Have the setter or an action method process the file.
The UploadedFile interface has methods for getting the name and size of the file, determining the file's MIME type (such as text/plain or image/jpeg), getting the file's contents as bytes or as a String, and writing the contents to disk. To learn more, in the Java editor, right-click on UploadedFile in a declaration statement and choose Show JavaDoc from the pop-up menu.
* To set the component's properties, select the component and edit its properties in the File Upload Properties Window.
* Right-click the component and choose one of the following pop-up menu items:
o Edit validate Event Handler. Opens the Java Editor with the cursor positioned in the component's validate method so you can insert code to validate the value of the component.
o Set Initial Focus. Gives this component focus when the user opens the page.
o Auto-submit on Change. Causes the form to be automatically submitted if the value of the component changes. Sets the component's JavaScript onclick property to common_timeoutSubmitForm(this.form, 'component-id');. At runtime, this code causes the form to be automatically submitted if the user changes the component value. Once the form is submitted, conversion and validation occur on the server and any value change listener methods execute, and then the page is redisplayed.
A component configured to Auto-submit on Change can use virtual forms to limit the input fields that are processed when the form is submitted. If the auto-submit component is defined to submit a virtual form, only the participants in that virtual form will be processed when the auto-submit occurs.
o Bind to Data. Bind the component's text property to an object or to a data provider. For more information, see Bind to Data Dialog Box.
o Property Bindings. Bind any of the component's properties to an object or data provider, such as the uploadedFile property to a bean property of type com.sun.rave.web.ui.model.UploadedFile.
o Configure Virtual Forms. Enables you to add the component to a virtual form.

Image / file upload error cannot upload image even after setting write permissions

Hi there everyone
I am having this problem when I try to upload a file (image file) to my server
I have a dynamic for working fine , all the other fields insert the information ok then I try to add an image upload behaviour to a file field
When I try to upload the file I get this error
Error:
An error occurred while inserting the records.
File upload error: File upload error. Error creating folder..
File upload error. Internal error.
Developer Details:
tNG_multipleInsert error.
An error occurred while inserting the records. (MINS_ERROR)
File upload error: PHP_UPLOAD_FOLDER_ERROR
File Upload Error. No write permissions in "../../productimages/" folder.
(FILE_UPLOAD_ERROR)
So I login to my server and change the write permissions to 777 and then try again and get the same message
I have closed DW and tried again and still get the same message......
I think I have followed all the steps correctly..... I have done the same type of forms many time and tested them locally on WAMP testing server and all work ok......
So..... Anyone got any ideas
Any help would be great
Have a nice day

My backend is only for admin, so they are the only ones who can access the
upload pages. My concern is an images folder on the site being 777. Can't
anyone from the outside plant a file in that folder if they just know where
to find it using an ftp program? ?

File Upload UI Element

Hi,
We are using the Standard Webdynpro File upload element in the screens. When the user clicks on the 'Browse' button the File Selector popuop is thrown using which the user can select the file.
Can we have on specific type of files be displayed in the 'File Selector' popup. currently ALL the files are displayed, though we have the option of '.html' files in 'Files of Type' dropdown.
How can we add custom file types say .csv file selection.
Regards,
S.Divakar

Baskaran,
The key here is "ACCEPT" attribute of file upload. Even if SAP add it later, we have to wait for MS to fix IE (make it true HTML 4.0 browser) -- IE docs even does not mention ACCEPT attribute on <input type="file" />
