Uploading file problem in JSF using myfaces-extensions.jar.

Dear All,
I'm new to JSF and trying to upload files using myfaces-extensions-1.0.9.jar and commons-fileupload-1.2.1.jar.

My problem is that it successfully run but when submit its not working and remain same page.

Down-/Upload files via Web Services using a NON-SAP system!?

Hello,
is it possible to down-/upload files via web services using a NON-SAP system!?
Regards,
Jens

Hi Jens,
I am not sure about your requirement here. What i could understand is that you want to check whether service could handle file processing?
1) Uploading file - You can build a Webservice which has import/export parameters as the file structures and implement the proxy class in such a way that the passed data is written to application server.
2) Downloading file - Same as uploading file, but the proxy class would have the code to extract data from the application server and pass them as output parameter.
Functionality of Non SAP system: The system which calls these services should be able to convert the output of proxy data into file in case of downloading the file and it should be able to convert the file data into export parameters in case of uploading file.
Hope this helps.

Prasanna

Uploading files to KM repository using Webdynpro APIs

Hi All,
I was reading the following blog /people/rohit.radhakrishnan/blog/2005/05/27/uploading-files-to-km-repository-using-webdynpro-apis and I was trying to upload a document from a URL for example http:/ntek.com.mx/wp-content/uploads/2008/12/sap_logo1.gif
So far I am getting the following error:
http:/ntek.com.mx/wp-content/uploads/2008/12/sap_logo1.gif (No such file or directory (errno:2))
Any Ideas?

Hi Jay,
So far I think I followed all the intructions given in the links you provide. This is the snipped code
IWDMessageManager manager = wdComponentAPI.getMessageManager();
          try {

               RID pathRID = RID.getRID(path);

               ICollection folder =
                    (ICollection) resourceFactory.getResource(

By now, OK. Here comes the problem: The behavior of application is correct after this, which I can see from the rest of my log, BUT my browser continue to say that the request is being processed and that the page continues to load, which is not true, and I can not find where is the reason.
Do you have any idea?

Check this code if it is useful

Visual Web JSF Portlet Upload file Problem in Websynergy

Hello,
I am using Websynergy milestone 3 release. I have tried to build AS A PORTLET the sample code, "Uploading Files in NetBeans Visual Web JSF Applications" (http://www.netbeans.org/kb/60/web/intro.html) using netbeans 6.5. The solution deploys successfully but unfortunately, the file Upload control does not work in the websynergy portlet environment. No file seems to be uploaded. The same code works very well in non-portlet environment. Is there a work-around for the Portlet environment?
Looking forward to some help!

Upload file component in JSF 1.2

Hi,
I am developing an application with JSF 1.2 . I am using a custom component made with Apache Commons FileUpload 1.2.1 API which purpose is to upload files. This component work only if the form data is encoded with the multipart/form-data encoding instead of the usual application x-www-form-urlencoded encoding. From what I know JSF 1.2 doesn't handle this type of encoding. To overcome this issue, I install a servlet filter that intercepts a file upload and turns uploaded files into request attributes. The problem is that when the form data is encoded with the multipart/form-data encoding no characters are encoded. I have other JSF components in this form and in them I put different international characters which are lost when the form is submit because they are not encoded.
Can somebody help me with this issue ?

How to upload files from a form using pl/sql ?

Hi
Is it possible to upload the physical files outside the database (under UNIX server)using pl/sql? I already know how to store the files inside the database(wwwdoc_documents$) but I didn't find any documentation about storing the physical files outside the database.
I have in my form the following component:
<input type="file" name="upload">
and I want to let the user browse for the file on his/her disc that he want to use. What I want to do next is to save a copy of that file on our file-server, and then use it in my application. How do I do that in pl/sql?
Any help will be appreciated.
Sebas.

Thanks for the suggestion. I like this approach as Java is more familiar to me than other languages.
Our DBA is out of touch today, so I could not grant the javauserpriv to my database user. I tried to run the script anyway in the chance that my user had the privs, and it seemed to have hung. I am now combing Oracle's site for more documentation so I can write some tests to see if I can get a basic Java object working. Under what heading would I find this?

MULTIPLE UPLOAD file problem

Hello,
I have a problem with multiple upload file tool.
Because my server need, in order to upload files in its folders, to be logged only with ftp user (that is unique).
Now, I need that when I upload a file its name will be stored on db table "file_name". But in order to put data in database i have tobe logged also with user that is allowed to access on mysql db.
So I understand that I should nedd to types of authentication at the same time...
I think it depends on my type of hosting that is windows, and there is not the possibility to change CHMOD, so the error when I try to upload a file is that the folder has not write permissions...
Any suggestions?
Thanks a lot

Hi ascaro231,
wow, that is one bag of problems on the remote side :-(
to be logged only with ftp user
although PHP itself provides native FTP functions
(e.g. for uploading files and also changing folder & file permissions), ADDT´s file upload features don´t support this protocol
and there is not the possibility to change CHMOD
CHMOD *will* have to be supported by your host, because this is how ADDT changes folder & file permissions.
Well, to me it seems that your host doesn´t provide some very basic and truly common-standard PHP settings -- and honestly, disabling the regular PHP file upload features is ridiculous.
Any suggestions?
go for a better host -- this is just inacceptable.
Are you hosting with "Aruba" BTW ? They have both Windows and Linux hostings, and AFAIK it´s possible to switch the hosting type.

at com.entertainment.system.EntertainmentFilter.doFilter(EntertainmentFilter.java:70)That is your own filter I'm assuming and line 70 of that filter is causing your exception. So check out that line to see what the offending code is.
I'm guessing that line does something with a parameter you retrieved, which is most likely null. A multipart form requires an API that can parse a multipart request, you cannot get file uploads (or other multipart fields) using the HttpServletRequest. I suggest you try out Apache commons FileUpload.

Uploading files a landing server using webutil

dear all,
i have the current situation and i'm looking for solution.
i'm using the webutil in order to upload files from the client side to a landing server, the situation here is :
when i use the following code
webutil_file_transfer.Client_To_AS_with_progress
(clientFile => :upload.file_name
,serverFile => 'd:\temp\'||l_bare_filename
,progressTitle => 'Upload to Application Server in progress'
,progressSubTitle => 'Please wait'
,asynchronous => false
,callbackTrigger => null
where d:\temp is alocal directory on the AS
but if i change the server file to a drive mapping i'll have the following error
WUT-132, my question here is it possible for the webutil to upload a file to another landing server other than AS?
how can i do it without making a hidden share to the folder ?
the other question if i have a firewall between the client and the AS, will it prevent the webutil uploading process ?

i want to add another point, when we make hidden share to the map drive the uploading worked successfuly.
what i need here is a way to access the map drive without making hidden share to the map drive?

Uploading files problem.

I have got a confusion in uploading files from user machine.
we use <input type='file' name='fileName'/> tag for that.
now at server side how we get the file:
request.getParameter('fileName'); ?
if yes then:
but getParameter function returns a string, and a file data (eg image file) can't represented as a string.
if no then:
what function of request object we should use for that purpose.
Now my second query is I have to get the size of the image, how will I be doing that.
Please help me in this context.
Thanks in advance for any help.

Hello,
Uploading file is a special request of HTTP.
You have to handle the request a different way.
Check on the JSP / Servlet forum for more information.
