Problem while uploading text file through portal into WebDAV repository .

Hi all...
I am not able to upload any file through portal onto my webDav repository for remote server however reverse is possible i.e. any document created at remote server is reflected in portal.
Everytime when i try to upload file though portal , i get the following error::
The item could not be created because an exception occurred in the framework.
Kindly suggest what to do....
ThankS

Hi Chetna,
Have you specified any user information in the webdav repository....Like always connect through this user, in the webdav repsository tab....This user may not have write permission in the windows.
Also are you sure that the user you logged in portal by which you failed to create new files or folders and the user that was able to create file in the windows are one and the same.....

How to change name of uploaded file

I am using the a multi-part form and the pl/sql gateway to enable users to upload files to portal. The files automatically get stored in the wwdoc_document$ table. The key to the file is a column called "name" which consists of a sequence number and the file type e.g. 4747.gif.. I want to change this name to a different value.
When I change it using the standard sql Update statement, none of the pdk apis work on the record; they all return errors. I am able to change this value as long as I use a unique value, I just can't run any of the wwdoc apis against the row after that.
Does anyone know how to change this value for a given row???

Questions about OAS Portal Forms to upload files

Hello,
I have quetions, about uploading files, see I need to creat a form that will be used by other people to upload information that later will be presented as downloads in the portal...
so I created a form in my provider with a file (binary) field, and it mimes to my table in the DB, to the field "Archivo", then what I do is use a omniportlet and using HTML format I present like a link using the info in the field Archivo
and when I clic on it it takes me to this link
http://desarrollo06:7778/pls/portal/38173.PDF
but the file I uploaded does not appear
can aniyone help me to solve this?
thanks in advances for the suggestions and your time ^_^

The method you used to setup upload of file seems fine. I suppose you would have used a blob type to save the file in your db table.
basically, you can develop a report offering a link calling perhaps a procedure which would query from the table and download the file.
In that procedure, you would look for the file (vblob) and the mime_type from that table using a sql-query. then use them to setup the mime type for the http protocol, and download the file as follows.
owa_util.mime_header(mime_type);
owa_util.http_header_close;
wpg_docload.Download_File(vblob);
hope that helps!

Hi,
I am downloading a properly working .par file from portal in my local system. But whenever I am uploading the same par file back into the portal through NWDS, the .par file is not running properly and its Giving error.
Here is the error:
"Caused by: com.sapportals.portal.prt.core.broker.PortalComponentInstantiationException: Could not instantiate implementation class com.tmobile.compSumm.CompSumm of Portal Component com.tmobile.CompSumm.CompSumm because: Could not find implementation class "
Any Idea what is the problem?????

Hi,
I have unzipped the .jar file from the .par file. Then I imported the .par file into NWDS. After that I have added the extacted .jar file as external jar into the project(Proerties->Java Build Path->Libraries->Add External Jars). After that I had uploaded the project into the portal.
But still its showing the same error:
"Caused by: com.sapportals.portal.prt.core.broker.PortalComponentInstantiationException: Could not instantiate implementation class com.ibm.test of Portal Component testing.test because: Could not find implementation class"
Any solution.....

Can u upload .htm file via portal app

If yes, then what is the taskflow i should use. i used Folder Viewer and Document Explorer and try upload this htm it gives me a popup with

thx

Did you check the following documentation -
http://docs.oracle.com/cd/E21764_01/webcenter.1111/e10148/jpsdg_doc_lib.htm#CIHCEACA
Also check the section -29.5 Setting Parameters to Upload Files to Content Repositories
where it is clearly mentioned -
"The Document Manager task flow allows you to upload files into content repositories. Oracle WebCenter Framework uses Apache MyFaces Trinidad to handle file upload from a browser to the application server."
and "To change the default settings of Apache MyFacesTrinidad, you can add three parameters to the web.xml file. To edit this file, open the ViewController project of your application. Under Web Content, open the web.xml file. In the Overview, navigate to Application > Context Initialization Parameters, then click the green plus (+) sign to add the parameters and their values (as described in Table 29-1) or simply update the code in the Source view. After you've made your changes, save the web.xml file, then restart Oracle JDeveloper.
Table 29-1 Apache MyFaces Trinidad Parameters
Parameter Description
UPLOAD_MAX_MEMORY
The maximum amount of memory in kilobytes that a single file can use when uploaded.
UPLOAD_MAX_DISK_SPACE
The maximum amount of disk space in kilobytes that a single file can use when uploaded.
UPLOAD_TEMP_DIR
The directory in which the file being uploaded is temporarily stored.
Provide the necessary information.
Hope it helps you to resovle the problem.

How can we limit uploading file size in portal.

we have a feature where customers can upload there files, we use portals for uploading files, form which has the file type is posted to a stored procedure and which in turns calls the wwv_things.saveitem.
we need to restrict a file size and file type for the uploading files, I can restrict the file type with javasript but wanted to find out if oracle portals has any way to restrict the uploading file size,
thanks and regards,
Sunil.

Currently, this is not available. You could have a query that has all RKF as a starting point to achieve this. If you think this would be good to have by default, please log a development request on the OSS Messaging System.

How to create a portlet to upload/delete files into portal pages

I wanted to know if it is possible to create a simple UI wherein a user could choose a file from his HDD and upload it to the page as an item.I know this can be done by editing the page,but when the user clicks on edit he would have to use the default portal interface to do the same, i want to avoid precisely that.
If possible then how do I go about making it.This UI would also require that the user be able to select from a list of previously uploaded files and delete some of them.This i require so that any authenticated portal user could access/downloaded the uploaded files given the url to the same.

You can use the WebDAV feature in Portal Release 2 to provide a simple interface for uploading and managing files. In addition, the content management APIs can be used to build custom interfaces. These APIs are available for Portal 3.0.9 and will soon be available for Release 2. There is no Delete API, but one is planned for an upcoming release.

Upload files from abap to portal

Hi,
I need to upload files (PDF) from Abap (R/3) to SAP Portal (into knowledge management).
I found 2 functions but I don't know if they serve to me:
BDS_BUSINESSDOCUMENT_CREATEF
SDOK_PHIO_STORE_CONTENT
Somebody can help me?
Thank you!!
Marc

Hello marc,
the two function modules you mention are:
1. is for upload in BDS (business document service)
2. is for upload to content server
i think both are not what you look for, they are not related to KM.
look at this, maybe it helps:

Upload a file to portal--- BW application server.

Dear All,
I have requirement where some part of business does not have SAP installed. But we would like to extract data from these business too.
So just wanted to know if we can have a scenario where user will upload the data to the portal (this is just a web portal). Can this be done?
Secondly, if the can be done, can we extract the file from portal to application server? From application then it becomes very simple to upload to data targets in BW.
Please help in this regard.
Thanks,
Sandeep

Assign an ID (e.g. 1234) to the uploaded file. You should abstract the store
so that it will work on the file system or in the database.
The JSP will include an image ref to that ID, e.g.
http://www.myco.com/myapp/imageservlet?id=1234
The image servlet will retrieve and stream the image. It has to set content
type etc. You should also verify that the current user has access to the
requested image if security/privacy is an issue.
Peace,

Hello i had exactly the same error, but not with file upload.
I'm sure you have in your application lib directory to jars which aren't compatible to each other.
And the problem occured between my myfaces and tomahawk jars .
See this page:
http://wiki.apache.org/myfaces/CompatibilityMatrix
It tells you which myfaces and tomahawk jars you can use together.
Hope it can help.
bye

Please help

The informations are really not much to have an idea about the problem.
The problem can be located in the fm that calls the file because is trying to search the file on a system where there are some kind of problems in the communication between the systems involved to read and pass the file. Did u map the file name with logical filenames ? Very strange problem. Can you browse in the server where the file is located . Is it on your pc ?
Or, there is some problem in the datas provided, but this problem should arise more when you save than when you just press to load.
With this kind of imformations is very hard to have an idea. You need to debug to see what s going on
