RE: HTTP File upload using WebEnterprise

AFAIK, WebEnterprise does not support the multipart-mime file upload
feature. I think this is something that is targeted for the next
release.
On a project here we wrote our own cgi program to handle file uploads,
but unfortunately this was not integrated with the rest of the Forte
backend. The suggestion from Forte was to make C++ calls into our Forte
service objects from our CGI. We haven't yet implemented this, but it
certainly seems like it will be possible.
By all means, let us know if you find a better mechanism than this.
It's certainly not the cleanest in the world.

Hi,
You should have a parameter called ServiceName in your request
(either in the URL or as a hidden parameter in the form) for any request
you send to fortecgi. The cgi uses this information to send your request
to the proper forte application.
In your example you would need something like this
<FORM ENCTYPE=3D"multipart/form-data" ACTION=3D"...." METHOD=3DPOST>
Send this file: <INPUT NAME=3D"userfile" TYPE=3D"file">
<INPUT TYPE=3D"submit" VALUE=3D"Send File">
<INPUT TYPE="Hidden",Name="ServiceName",Value="MyService">
</FORM>
MyService is the name is the name you have given for the service when
you call EnableAccess in your subclass of HTTPAccess.
This is all explained in the Web Enterprise /SDK manual.
Note : You would also need a parameter PageName when using Web SDK. I
have not used Web Enterprise yet but I presume it is the same there too.
Hope this helps

File uploads using jQuery with jquery.fileupload.js fails in Firefox over SSL

Please see the link below where I originally posted the question.
http://stackoverflow.com/questions/27792614/file-uploads-using-jquery-with-jquery-fileupload-js-fails-in-firefox-over-ssl

Thanks. In my estimation that is exactly the issue. But that doesn't help with a resolution.
The actual file size: 945,991 bytes
If Firefox is miscalculating the length (in Safari/Chrome 945991 and 946241 in Firefox), then Firefox is reporting erroneously and should be raised as a bug in Firefox, would you agree?

File Upload using Flex/ColdFusion. 2044 error

I am looking for a little more clarity around the file upload using Flex and Cold Fusion. When I run this using my server I get Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.
I did create a regular cfform and had it use my ColdFusion upload form and that worked fine, so I feel good about the upload form. I am starting to think there is a permission error with the Flash Player writing to the folder. When this is ran, it will show the file being 100% loaded but the complete event is never triggered. I put alerts to see where it hits and 100 does show at the same time as my error message. The complete alert never shows. I also put an alert in my cfm page and it never reaches that page to hit it. Whether I use an absolute URL or relative path. I have also tried the urlrequestmethod.post and nothing changed. Thanks in advance. BTW. I am using Flex 3.

Presumably you need to add a result handler to your request.

File uploads using servlets to oracle8i database

Hi,
Help please, How I can a File Upload using BLOB's into the oracle database, any sugestions...
Thanks
Moacyr
[email protected]

Try the jason hunter book Java Servlet Programming for a very good description or the web site hosted by o'reilly
www.servlets.com
Has a very neat java class for decoding multipart mime encoded files (the upload stream from the browser). Seems to accomodate most of the differing browsers intretation of the standard.
Note to Oracle: This should really be handled by the servlet engine as an Oracle extension. Where the servlet engine strips the mime encoding out before the servlet is called placing the decoded file in an associated extension call. ie: cast the request to an Oracle request object which has file uploaded method.

URGENT.........File Upload using Servlets and jsp

I am a new servlet programmer.......
iam using tomcat server......
can any one pls help in writing code for file upload using servlets and jsp without using multipart class or any other class like that....
Please URGENT..

Slow down! "Urgent" is from your perspective alone. I, myself, am not troubled or worried in the least.
hi ugniss
thanks for ur reply....sorry i was not
y i was not asked not to use multipart class or any
other class like that...is there any other
possibility to do file uploading from jsp to
servlet...
Just as an aside, a JSP is a Servlet. But even if I move beyond that, the question does not make sense. If you want a "JSP to upload to a Servlet", then simply do so in memory. You are still (likely) within the same scope of a given request. However, if instead you are referring to a JSP that is displayed on a browser, then really you are talking about HTML, which is what the browser will receive. And since you are now talking about a browser, your only real, viable option is a multi-part file upload. So, it is either server or it is browser. And either way, the question leads to very established options, as outlined above.
the main concept is.. in the browser the user selects
a particular file and clicks the button upload..after
clicking upload the jsp should sent the file to the
servlet in streams...there the servlet gets in and
saves in a server location........this is wat i hav
to do...
Okay. So, after reading my previous (redundant) paragraph, we have arrived at the crux of the issue. You have a JSP that will be output as HTML to a client (browser) which you want to upload content to your server (handled by a Servlet). So, you are now stuck again with multi-part. The requirement to not use multi-part is non-sensical. You can overcome it, say, if you write your own applet or standalone Swing client. However, if your users are invoking this functionality from a browser, you are limited by the options that W3C has provided you. Use multi-part.
is there aby possibilty to do this.....can any one
pls help....Take the advice to download and review Jakarta Commons FileUpload. Inform your management that their requirement makes no technical sense. Research on your own. There are dozens of examples (and tutorials) on file upload using multi-part. Embrace it. Live it. Love it.

Reliable file upload using JDev, AS and other

Hello,
I'm not sure this is the right place to post this message, sorry if I was wrong to put it here.
The question is our company is developing software, for active data exchange with other systems. We decided to exchange in xml format, by means of both web services and web interface (so that exchange could happen both automatically and on user request). We use JDev to develop, Oracle AS to deploy application. Systems we exchange can use various platforms, in fact, it doesn't matter what exactly they use. The question is we need a reliable way to exchange large (sometimes small, but can be 1Gb or, for example, 10Gb) files, maybe with appropriate security, so that it could continue if something happens with network connection.
One simple decision is to have a web service that accepts, for example, 100K at a time, and another service continuously calls it until file is transfered. So it can check response code. But are there better decisions? I think, there are libraries or smth like this?
Thanks in advance, believe, it's a right place to get help.
Valeriy

Another, simpler (we think), such package is Jenkov HTTP Multipart File Upload. It's a servlet filter which can work in front of both servlets and JSP's. The servlet filter parses the uploaded file and stores it temporarily on the servers disk. When the servlet or JSP executes afterwards, it can obtain all the information about the file, from the request attributes. There is a decent manual for HTTP Multipart File Upload on the website.
Just search for "Jenkov HTTP Multipart" on Google and you'll find it. HTTP Multipart is free, open source, Apache Licsense.

HTML File Upload - using DAD - Error

I have set up my document table, the document upload package is in there, but my HTML for the file upload is not working correctly:
DAD info
DAD Name: /pls/portal

</html>
But i get this error when i try to upload a doc:
The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.
anyone have any insight on how to get the file upload to work (specifically how to configure the HTML to correctly use the upload process?

File Upload using Tomcat 5.x Apache 2.x

Hi,
Once I updated my tomcat 5.x to apache 2.x and ran my upload jsp code using java api i wrote to upload file to server, all pictures or videos received seems distorted.. At first i thought of bit shift or something but when i upload a textfile all look right.. Anyone know what the heck is going on before i disect my code.
thanks
henry

make sure your modjk logs don't have any errors.
Here's a peice out of my httpd.conf
#ADDed Oct 15,2003, seemed to remove modjk error
AddType multipart/form-data .gif .png .jpg .peg .jpeg .jpeI used to get strange modjk logged errors.
Also did you compile jk2 from source???

But if my bit shift is correct wouldn't my regular textfile upload be distored?From what I remember, the problem is something to do with logical AND or OR, with the bits. Apache receives it fine, passess it through jk, and and either the most sig or least gets lost. Image data is critical as every bit counts, text file, you may not notice it(white space), or every nTH file upload might fail.

File Upload Using WebDynpro

Hi All,
I want to upload single or multiple CSV files using a user interface written in WebDynpros. The files will then be parsed and converted to XML.
I did something similar with jsps earlier but am not sure how to go about it with WebDynpros.
If anyone has already done something similar then please share your views.
Thanks in advance.

File Upload using WD ABAp

HI,
I am working with a File Upload Web Dynpro Application. And i am using the File Upload UI Element to do this, every thing works fine.. i upload the file and show the error records in the other page.. and in the second page i have a back button, when i press the back button it should come to the first page . But the problem here is when ever i come back to first page from second page, the file path that i already selected is not visible in the file upload UL element , how ever the file name is still available in the context attribute that this FILE UI element is binded to..
One more thing that i have observed with this control is i am not able to set a default value to this say 'c:\'.
Is there any property that also me to have this defualt value and the value persistance for this UI..
or.
could you please suggest the other ways of doing this file upload withoout using the File Upload Control.
Thanks
Mahesh

This is actually problem with FileUpload element in WebDynpro which is because of IE and not even in control of WDA.
For more details plz check the below link
http://help.sap.com/saphelp_nw70/helpdata/en/b3/be7941601b1d09e10000000a155106/frameset.htm
I am pasting the detail here.
Technical Browser Details Beyond the Control of WDA
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Due to browser restrictions that are unrelated to Web Dynpro ABAP, the previously entered data path might disappear when a FileUpload UI element is clicked. In newer versions of the browser, it is therefore impossible to enter the file name in the entry field. The field always remains empty. For more details, read the security-related information in Internet Explorer 6 about handling <input type=file>.
The path might also disappear if an incorrect path name is entered in this field. This also has to do with security aspects in the browser. For security reasons, the browser only accepts absolute paths or a pack selection via the Browse key. If the path name is incorrect, the browser will not even forward the request.
The FileUpload of WebDynpro is very Primitive.
I dont think there are methods to set filters and initial path. Please let me know if you are able find a way.
Thanks,
Anand

Error in File uploading using jsp

My uploading code in jsp is as follows.
     <% try{
          Class.forName("org.gjt.mm.mysql.Driver").newInstance();
          Connection dbCon = DriverManager.getConnection("jdbc:mysql:///uoc");
          out.println("Connection done !");
          Statement stmt = dbCon.createStatement();
          out.println("Statement Created !");
ResultSet rs = stmt.executeQuery("SELECT * FROM blob_test)
stmt.close();
dbCon.close();
out.println("<br><br> <b>Data Successfully selected !<b>");
} //try
catch(SQLException e){
     out.println(" <br> ");
     out.println("Sorry ! problem in selecting a data "+e.toString());
     out.println(" <br> ");
               e.printStackTrace();

Please help .I thank You in advance for any help .

Have you tried increasing the BLOB field greater than 1048576 or using a smaller file of say 1 or 2k as a test? There is no guarantee that the database will store the file with exactly the same size as the file on the filesystem, so the file might be more than 916k in the database.
Using BLOBs is a great way to destroy the performance of your database by the way :)

Problems with file upload using AMF or SOAP

We use your AMF to connect Flex with Ruby on Rails.
Everything is OK, except file upload.
We did not find how to upload file using AMF or SOAP RPC from
Flex. Only to use FileReference.upload().
The problem is that Flex uses different User-Agent in HTTP
header for this upload and for SOAP/AMF calls.
This means that sessions are different. And even if you
authenticated via SOAP/AMF you can not use it to upload file.
Could you, please, advice is there any other way to upload
files from Flex via SOAP or AMF?

Please, help me on this issue, i am still waiting for someone replying me!

File upload using uiXML and Struts

Hi,
I am using Struts as my controller component with uiXML for the UI. I need to add file upload functionality to one of my pages. After a bit of trial-and-error, I figured out that the following code in my uiXML sets me in the right direction -
<struts:form name="myForm" method="post" beanName="myFormBean" usesUpload="true" destination="/try/SaveTry.do">
When the "destination" attribute is not specified, the Struts action does not get the file. However, with the changes above, the uploaded file now reaches my Struts action, which does the necessary processing and the Struts controller forwards the control to the next page according to its logic.
However, at this point, I see the following on the browser -
java.io.EOFException

I tried to specify my own file upload manager (which does nothing) and also tried to subclass the UIXPageBroker to return false in shouldHandleUploadFile() and null in decodeMultipartRequest(), all to no avail.
Could somebody please let me know if I am missing something? Why is the AbstractPageBroker still kicking in after my file upload has been processed?
Thanks in advance,
Smarto

File upload use pl/sql with OAS 4082 and 8i/EE

is there any way to upload/download files (any format) from web browser use FORM and above env. Don't mention samples in OAS document, it simply doesn't work. thanks.

I probably wrong but I interpret this as POST is not supported, http://download.oracle.com/docs/cd/E11882_01/appdev.112/e16659/xdb22pro.htm#ADXDB5550, "Supported HTTP(S) Client Methods"
It says:
"+The semantics of these HTTP(S) methods is in accordance with WebDAV. Servlets and *Web services may support additional HTTP(S) methods*, such as POST.+" (my emphasis - so yes, it is supported).
Today we are using an Appserver with HTTP mod_plsql, the code for the form looks like:
htp.formopen (
curl => 'FileUpload',
cmethod => 'POST',
cenctype => 'multipart/form-data');
the "FileUpload" takes care of the file and inserts it in the dbThe question is how does it do it? A file upload via mod_plsql/EPG is done via the PLSQL document table. It, mod_plsql/EPG, takes cares of the actual upload part - reading the Mime stream of the upload from the browser and inserting it into the document table.
Unfortunately, seems that the 11g documentation lacks details in this regard. Please consult the Oracle® HTTP Server mod_plsql User's Guide (10g).
<li>section 1.7.1 describes the format of the upload table you need to define
<li>section 1.7.4 shows a sample HTML form doing a HTTP post, and the post-process upload PL/SQL procedure that needs to be written to process the contents of the row just created for the uploaded file in the document table
