File upload example - browser freezing

We implemented the web file upload example in Forms 6i a while ago. It seemed to work however if we load several files in one session the browser freezes - has anyone else experienced this problem? Can anyone help?
Many Thanks

Problems with File Upload Example

Hi,
I follwed all the steps as in File Upload Example, still I am getting this exception,
Exception occured in J2EEC Phase

Help:simple file upload example not working

Request input on what's wrong with this -
Using JDeveloper 10G.
1) I created a simple jsp file upload file using the OJSP
File Access Tag library options. With empty JSP file,I
dropped in the httpUploadForm and the httpUpload tags.
Now when I run this I get the following error stack on
the web page.
javax.servlet.jsp.JspTagException: Posted content type isnt multipart/form-data at oracle.jsp.webutil.fileaccess.tagext.HttpUploadTag.doStartTag(HttpUploadTag.java:130)at test4.jspService(test4.jsp:10)[test4.jsp]
2)Now if I use a simple JSP without the tag library - the
page fails to display. Found that commenting out the
line "upbean.upload()" lets the page run and atleast
show me the upload form. What's wrong with this
standard example from the OC4J documentation -
<%@ page import =
"javax.servlet.http.*,
java.io.*,
java.util.*,
oracle.jsp.webutil.fileaccess.*;" language="java" session="true" contentType="text/html;charset=windows-1252"
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Upload</title>
</head>
<body>
<% String userdir = "mydir"; %>
<form action="pUpload.jsp" ENCTYPE="multipart/form-data" method=POST>
<br>
File to upload: <INPUT TYPE="FILE" NAME="File" SIZE="50" MAXLENGTH="120" >
<br>
<INPUT TYPE="SUBMIT" NAME="Submit" VALUE="Send">
</form>
<jsp:useBean id="upbean" class="oracle.jsp.webutil.fileaccess.HttpUploadBean" >
<jsp:setProperty name="upbean" property="destination" value="<%= userdir %>" />
</jsp:useBean>
<% upbean.setBaseDir(application, request);
//upbean.upload(request);
%>
</body>
</html>

It's not clear from your post, but are you aware that the
documentation is really showing multiple files?
The doc examples are based on the ones you can try out by downloading the ojspdemos.ear file.
They use discrete steps. For example, the fileUploadIndex.html contains the following
This will call the form and set the action in the form to call the tag upload jsp file. The form will do the multi-part post and the tag upload file does display the text after the <upload:httpUpload> tag. I just re-ran the example to be sure.
The same basic mechanism applies to the upload bean. That is it is called via:
This is the only way that these can work because the upload code (beans & tags) both require a multi-part post. I hope this helps

Problem with Multi File upload example, help needed

I got the code from the following location.....
http://www.adobe.com/devnet/coldfusion/articles/multifile_upload.html
And I've got it to work to some degree except I cant get the file transfer to work when pressing, Upload.   Below is what my debugger outputs. Any thoughts on how to fix this or even what it means?
At the very bottom of this message is the upload.cfm code.......

Just 2 things in my test:
1) I use no accept attribute. Coldfusion is then free to upload any extenstion.
Restricting the type to application/octet-stream may generate errors. Also, it is unnecessary, because we perform a type check anyway.
2) I have used #ExpandPath('.')#\ in place of #ExpandPath('\')#

Flex and php file uploader cross browser problems

Hi, I have a problem in flex and php file uploader. It was
working fine in Internet Explorer, but nothing would work in
Firefox and in other browsers. Firefox and other browsers was not
sending the session with the file upload and was producing a login
error. On IE the session cookie is picked up and the upload request
uses the authenticated session, no login error. I'm newbie in flex.
Please help me. Thanks in advance!
Here's my code:
bgupload.mxml

Hello, I am Gamaliel Arredondo, i have solved this problem, the error is in the code, you have a mistake in your code, check it out.
The way to run the flex applications, in my case, i installed xampp, in the htdoc directory i put the folder with the files of the application and all is working very well, only when the apache is running because if it is stoped the application show error, please review your code and if you have problems you can contact me by e-mail ([email protected]) i also fought with that problem but i could find the solution, i hope to help you.

File Upload Example in ADF Development Guide

I tried to upload a file using ADF as described in Development Guide. I have taken a <af:inputFile> component as described.
<af:inputFile label="#{res['srfileupload.uploadlabel']}"
valueChangeListener="#{backing_SRFileUpload.fileUploaded}"
binding="#{backing_SRFileUpload.srInputFile}"
columns="40"/>
[Page 620]
Now, what is the type of that variable "srInputFile" in the backing bean?
Is there any full written code for this ADF Development Guide example? Where from can I download that?

All the needed code is on page 617 of the ADF Dev Guide 10.1.3
http://download.oracle.com/docs/pdf/B25947_01.pdf
It is also located in the SRDemo ADF Tutorial support files

Well Well Well..
That would not work...
What you have to do is save the uploaded file content on to a location and then pass the fileName as a request parameter to a deidicated which displays the contents of that file.
Just as an example
<html>
<head>
<title>File Upload Display</title>
</head>
<body>
<%
//ServletOutputStream sout=response.getOutputStream();
StringBuilder strBuilder = new StringBuilder();
int count=0;
String f;
f=request.getParameter("filedb");
DBManager dbm = new DBManager();
//dbm.createTable("mms3");
//log.info("In JSP : "+ f);
//dbm.insert_data(f,"mms3");
%>
<%
if (ServletFileUpload.isMultipartContent(request)){
ServletFileUpload servletFileUpload = new ServletFileUpload(new DiskFileItemFactory());
List fileItemsList = servletFileUpload.parseRequest(request);
strBuilder.append("<?xml version=\"1.0\" encoding=\"UTF-8\" ?>").append('\r').append('\n').append("<xpage version=\"1.0\">").append('\r').append('\n');
String optionalFileName = "";
FileItem fileItem = null;
Iterator it = fileItemsList.iterator();
ServletOutputStream outputStream=null;
while (it.hasNext()){
   FileItem fileItemTemp = (FileItem)it.next();
%>
Name-value Pair Info:
Field name: <%= fileItemTemp.getFieldName() %><br/>
Field value: <%= fileItemTemp.getString() %><br/>
<%
if (fileItemTemp.getFieldName().equals("filename"))
    optionalFileName = fileItemTemp.getString();
if(!fileTempItem.isFormFiled()){
   String fileName = fileItem.getName();
   fileItem.write(optionalFileName);
%>
Uploaded File Info:
Content type: <%= fileItem.getContentType() %><br/>
Field name: <%= fileItem.getFieldName() %><br/>
File name: <%= fileName %><br/>
<%
if(fileItem.getContentType().equals("image/jpeg") || fileItem.getContentType().equals("image/pjeg")) {
%>
<img src="FileServlet?fileName=<%=optionalFileName%>"
<%
%>
</body>
</html>a sample code snippet for FileServlet.
String fileName = request.getParameter(fileName);
File file = new File(fileName);
   if(!file.exists())
     return;
// If JSP
String mimeType = application.getMimeType("fileName");
       If you are using servlet
       String mimeType = this.getServletContext().getMimeType(fileName);
     response.setContentType(mimeType);
     response.setHeader("Content-Disposition","inline;filename=\\"+fileName+"\\");
BufferedOutputStream out1 = null;
InputStream in = null;
if(mimeType == null)
     mimeType = "application/octet-stream";
try{
     in = new FileInputStream(f);
     response.setContentLength(in.available());
     BufferedOutputStream out1 = new BufferedOutputStream(response.getOutputStream(),1024);
     int size = 0;
     byte[] b = new byte[1024];
     while ((size = in.read(b, 0, 1024)) > 0)
        out1.write(b, 0, size);
}catch(Exception exp){
}finally{
      if(out1 != null){
         try{
            out1.flush();
            out1.close();
         }catch(Exception e){}
      if(in != null){
        try{in.close();}catch(Exception e){}
} Hope that might answer your question :)
However,this is not the recommended way of doing this make use of MVC pattern.Would be a better approach.
you might think of googling on this and can findout what is the best practise followed for problems of this sort

Uploading a Specific file rather than browsing

My app allows users to create a user-named jpg like so:-
var enteredimagename:String = imagenameentry.text;
var file:File = File.applicationDirectory.resolvePath(('assets/images/')+enteredimagename+('.jpg'));
However I now want to allow a user to upload that specfic file automatically to my server by clicking a button which will simply upload that file WITHOUT having them browse for it. So basically I need it set up so that when the user clicks a button whatever name they type into the imagenameentry.text will be the image that gets uploaded. For example they create an image which they name yahooimage by typing yahooimage into the imagenameentry text input component. Once a button is clicked this will save this image as assets/images/yahooimage.jpg but I want to advance this button click further so that this specific jpg is then set as the file for upload without browsing for it. All the examples I've seen use the browse function though which is not what I want.
How can this be combined with the filereference method or some other way so that the file to be uploaded can be entered into a textinput component as described above rather than browsed for?

Hi David,
go through these docs: [Doc1|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/00062266-3aa9-2910-d485-f1088c3a4d71]

Can not select a PDF file in the file uploader window after clicking the Browse... button for a file type input element.

After upgrading to 5 (this worked in 4) I can not select a PDF file in the File Upload dialog that appears when I click the Browse button next to an HTML file type input element. The specific HTML element source code has the attribute: ACCEPT="image/*". I can select image files such as jpg, png, tiff, etc. But not PDF. This worked great in Furefox 4 and works in the latest version of Safari.
The HTML code for the form element is:
INPUT TYPE="file" NAME="file_1" ACCEPT="image/*" SIZE=35
The File Upload dialog lists all files with PDF extension as dimmed and not selectable in Firefox 5.
Can you help?

Hi Purush
Unfortunately we couldn't solve the problem. Our IT specialist checked it with SAP directly. SAP doesn't support the SAP KW solution anymore. Therefore we checked-in the document in ".doc"-Format.

All plugins uptodate but on upload file get "USING one of the supported browser with latest Adobe Flash is required to experience enhanced file upload features

I am freelancer. When I tried to upload files on elance it give following error and disable the upload button:using one of the supported browser with latest Adobe flash is required to experience enhanced file upload features.
All plugins are up to date. Flash version 11.7 installed.

I assume Firefox 19 worked fine on the site?
Some sites may be mistakenly identifying Firefox 20 as Firefox 2, which is a very old version they probably no longer support. As a test, you could "lie" to the site about your Firefox version and see whether that little deception works.
This take a minute to set up. Here's how:
(1) Select and copy the following preference name to the clipboard:
general.useragent.override.elance''.''com
(2) In a new tab or window, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(3) In the filter box, type '''override''' and pause while the list is filtered
(4) Make sure '''general.useragent.site_specific_overrides''' is set to its default value of true (or right-click and choose Reset if it is not).
(5) Right-click anywhere in the preference list area and choose
New > String
then paste the preference name you copied. Click OK and enter TEMP or asdf or any text as a temporary placeholder. You should see the preference added in bold. Leave about:config open and switch back to this tab.
(6) Select and copy the following useragent string to the clipboard ''(it's all one line)'':
Mozilla/5.0 (Windows NT 6.1; rv:19.0) Gecko/20100101 Firefox/19.0
(That's Firefox 19 on Windows 7 32-bit)
(7) In about:config, double-click '''general.useragent.override.elance''.''com''' and paste to replace the temporary text with the new useragent string. Click OK, you're done here.
Now try reloading a page where you need to upload (use Ctrl+Shift+r) and test that function again. Any change?

File Upload in Web Dynpro

Hi all,
I need to upload file from user local computer into Web Dynpro context, but standard FileUpload component doesn't look very "attractive" to me. There are 3 main reasons:
1. when user don't use Browse functionality, but he/she types directly for example == "xxxx" (not valid absolute windows path) into input field of FU Component and then click Upload, application freeze - and loading that 'file' forever.....
2. don't know how to specify custom file types in showed FileChooser (predefined are AllFiles, Pictures, HTML)
3. Browse label is not internationalized, no possibility to change that text (and that button also looks "different" )
How can I eliminate these minuses, or is here alternative solution for file uploading file in WD? My customer environment is NW 2004.
Regards,
Juraj

Dynpro UI elements has limitations. But we can use them the way we want within these limitations.
1. when user don't use Browse functionality, but he/she types directly for example == "xxxx" (not valid absolute windows path) into input field of FU Component and then click Upload, application freeze - and loading that 'file' forever.....
If there is a fixed place to hold the documents, we can prefix the path upto the filename.
2. don't know how to specify custom file types in showed FileChooser (predefined are AllFiles, Pictures, HTML)
we can get the MIME type from the resource. And further processing can be restricted.
3. Browse label is not internationalized, no possibility to change that text (and that button also looks "different" )
I Agree that we can't change "Browse", but still we can have the orientation, if your browser is Arabic, it got aligned at right hand side.

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.

Validation error after File upload

HI,
I am using a file upload functionality in OAF page.
When i browse for the required excel file and click on browse, the data is popluated on the oaf page.
I have 2 lov fields on page - say a & B.
B is a dependent LOV on A.
I have a validate button on my page which gets enabled only after file upload and validates if the data is correct or not.
The issue is like if i am having value in upload file for A as 1 and for B as 1800, but my LOV B has 2 values 1800 & 1800-01 for LOV A = 1, it gives me an error at that LOV "Select a Valid Value". If i open the LOV B window and select 1800 from it the data is correctly validated without any error.
Please help me that how can i rectify this error i.e. it should validate the data corrrectly if i pass the value 1800 to it thru excel sheet.

See take an example of Employee name LOV .We know for every employee a unique emp Id is related to it.So if two person are having same name also then also their ID is different.In such cases , while creating LOV we create a FormValue for EmpID .Its not visible on Page but while validating the page formValues are also considered thereby it doesnot cause invalid value error...
In Your case, what you can do is the way you are populating the LOV field you can populate this FormValue to remove the Error.
Please Refer Jdev Guide for more info..
Hope it helps!!!
Thanks
AJ

File upload onComplete failing

I'm using the FileReference.browse method to allow users to
uplodd an .mp3 to a script. I am using AS2, publishing to Flash8. I
am looking for and logging events ... when I first created this the
oncomplete returned success and the file uploaded fine. Somewhere
along the line oncomplete started to fail, yet the file still
uploads. However now the flash player continues to attempt to open
the file it seems, as my CPU pegs with seconds and the browser
hangs. I can't see that I changed any code in the browse method,
which I grabbed directly from Flash Help. I had changed the
oncomplete to onCompleteData but that's not working either. Any
thoughts out there?
Here is an example of what I mean (please have an mp3 ready
to upload.
Here's
one if you need it.):
