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.

How do I import an InDesign tagged text file into multiple pages and export as .ps or .pdf using Jav

I have an InDesign tagged text file I've translated from .xml. I need to automate the following steps:
1 - access specific InDesign template (eg. ABC_template.ind)
2 - import tagged text file into InDesign
3 - autoflow text to END of document (normally around 3-5 pages)
4 - save document as either .ps or .pdf file
5 - where the input file stub name matches the output stub name (eg., OrigName.txt outputs as OrigName.pdf).
I would like to completely automate this whole process using JavaScript (because I don't know anyone that knows AppleScript). I've automated the first part using a perl script. I've been trying to find sample snipits of JavaScript that would do one or more of the items listed above, but am having a hard time finding what I need.
Please, I'm desperate!! Can any of you InDesign scripting guru's out there help me??
Thanks in advance!!

How do I upload XML files into sap table?

Dear all,
I found some methods that upload xml into SAP,
but there doesnt work under 4.6c.
Can someone tell me how to upload XML files into
sap under 4.6c?
THX!

hi,
You can convert XML to abap using transformations. Simple transformations is a proprietary SAP programming language that describes the transformation of ABAP data to XML (serialization) and from XML to ABAP data (deserialization).
goto SE80->workbench->edit object(or other objects)->in object selection chose more tab and then choose the transformation radio button and write a name and click create new.
Here you enter your transformation like
<xsl:transform version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:sap="http://www.sap.com/sapxsl"
>
<xsl:strip-space elements="*"/>
<xsl:template match="/">
<xsl:copy-of select="."/>
</xsl:template>
</xsl:transform>
You can use this transfomation in your program using call transformation. You can find more info on call transformation in help.
Hope this helps.

Richa

How do I allow users to upload personal files through website?

How do I allow users to upload personal files through our website?
I am trying to allow the visitors the ability to upload images for a future contest we will be hosting. I am trying to build a submit form with personal fields (already got this done) along with a field they can upload 1 or 2 images. I want the form to send me an email with details along with image files. I have a BC webbasic+ account and I am using Muse for my web editing.
Can someone point me in the right direction?

Hi,
You could apply a "file attachment" field within the web form. If needing more than 1 file attachment you'll need to access your form code and hard-code the additional field.
The form will collect the file(s) and will be held within the case details under "related files". You can also assign a workflow to recieve notifications however only 1 file will appear in each email. To see the other files you'll need to access your order details.
All this can be create and managed within your site's admin. yoursite.com/admin
Within the site admin...

How to upload a file into file system on server?

We want to allow our partners to upload .csv file on our unix box. How do we upload a file into file system. I might be wrong but after reading the documentation, I think OA framework only allows to save the file in database. Please advise.
Thanks,

Hi,
I was making a very silly mistake and found it. We need to create a new Entity object before you try to fill it with data. So what we can do is in the Controler, call a method in the AM that creates a new entity object (this should be made in processRequest, so that the VO gets initialized when the page loads).
Now you can fill the entity with data in the page (ie browse and choose the file), and then when the page is submitted call a method AM again but now in processFormRequest to do the commit.
code example
In the AM class
* Creates a new createCVRecord. To be Called from ProcessRequest when the page loads.
public void createCVRecord()
XxPersonCVVOImpl vo = getXxPersonCVVO1();
if (!vo.isPreparedForExecution())
vo.executeQuery();
Row row = vo.createRow();
vo.insertRow(row);
// Required per OA Framework Model Coding Standard M69
row.setNewRowState(Row.STATUS_INITIALIZED);
} // end createCVRecord()
* The commit method. To be Called from ProcessFormRequest when the page is submitted.
public void apply()
getTransaction().commit();
or else there is a different way... please refer the following thread for more details....

How to batch upload PDF files into database BLOB

Hello.
I have a requirement to batch upload PDF files into BLOB column of an Oracle 8.1.7 table from Forms 6i Web. The content of the blob column (ie. the PDF content) MUST be displayable from all client software (eg. Oracle Web forms, HTML forms, etc.)
Our environment is
Middle-tier is 9iAS on Windows/2000
Database is Oracle 8.1.7.0.0 on VMS
Oracle Web Forms 6i Patch 10
Basically my Oracle web form program will display a list of PDF files to upload and then the user can click on the <Upload> button to do the batch upload. I have experimented the following approaches but with no luck.
1. READ_IMAGE_FILE forms built-in = does NOT work because it cannot read PDF file. I got error FRM-47100: Cannot read image file
2. OCX and OLE form item = cannot use this because it does NOT work on the Web. I got error FRM-41344 OLE object not defined
3. I cannot use DBMS_LOB to do the load because the PDF files are not in the database machine.
4. Metalink Note 1682771.1 (How to upload binary documents back to database blob column from forms). When I used this, I got ORA-6502 during the hextoraw conversion. In using this solution, I have downloaded a bin2hex.exe from the Google site. I've noticed that when I looked at the converted HEX file, each line has the character : (colon) at the beginning of each line. I know the PDF file has been converted correctly to HEX format because when I convert the HEX file back to BIN format using hex2bin.exe, I'm able to display the converted bin file in Acrobat Reader. When I removed the : (colon) in the HEX file, I did NOT get the ORA-6502 error but I CANNOT display the file in Acrobat Reader. It gives an error "corrupted file".
5. upload facility in PL/SQL Web toolkit - I tried to automatically submit the html form (with htp.p) but it does NOT load the contents of the file. I called the URL from Oracle forms using web.show_document. There seems to be issues with Oracle Web forms (JInitiator) and HTML (+ htp.p).
The other options I can think of at this point are:
1. Use SQL*Loader to do the batch upload via SQL*Net connection and use HOST() built-in from Oracle Webforms to execute SQL*Loader from the 9iAS.
2. Write a Visual Basic program that reads a binary file and output the contents of the file into a byte array. Then build a DLL that can be called from Oracle webforms 6i via ORA_FFI. I don't prefer this because it means the solution will only work for Windows.
3. Write a JSP program that streams the PDF file and insert the contents of the PDF file into blob column via JDBC. Call JSP from forms using web.show_document. With this I have to do another connection to the database when I load the file.
4. Maybe I can use dbms_lob by using network file system (NFS) between the application server and VMS. But this will be network resource hungry as far as I know because the network connection has to be kept open.
Please advise. Thank you.
Regards,
Armando

I have downloaded a bin2hex.exe from the Google site.
... each line has the character : (colon) at the
beginning of each line. I'm afraid it isn't a correct utility. I hope you'll find the source code of a correct one at metalink forum:
Doc ID: 368771.996
Type: Forum
Subject: Uploading Binary Files: bin2hex and hex2bin do not reproduce the same file
There is some links to metalink notes and some example about working with BLOB at http://www.tigralen.spb.ru/oracle/blob/index.htm. Maybe it helps. Sorry for my English. If there is any problem with code provided there, let me know by e-mail.

How to upload a file into server using j2ee jsp and servlet with bean?

How to upload a file into server using j2ee jsp and servlet with bean? Please give me the reference or url about how to do that. If related to struts is more suitable.
Anyone help me please!

u don't need j2ee and struts to do file uploading. An example is as such
in JSP. u use the <input> file tag like
<input type="file"....>You need a bean to capture the file contents like
class FileUploadObj {
    private FormFile srcFile;
    private byte[] fileContent;
    // all the getter and setter methods
}Then in the servlet, you process the file for uploading
    * The following loads the uploaded binary data into a byte Array.
    FileUploadObj form = new FileUploadObj();
    byte[] byteArr = null;
    if (form.signFile != null) {
        int filesize = form.srcFile.getFileSize();
        byteArr = new byte[filesize];
        ByteArrayInputStream bytein = new ByteArrayInputStream (form.srcFile.getFileData());
        bytein.read(byteArr);
        bytein.close();
        form.setFileContent(byteArr);
    // Write file content using Writer class into the destination file in the server.

How to create OEMS JMS In-Memory and File-Based Persistence?

Anyone knows how to create OEMS JMS In-Memory and File-Based Persistence? Any help it is appreciated. I m working with Oracle BAM 11g TP4 and I want to test the capability of connecting directly to a JMS queue, and reading Oracle´s "complex" documentation I couldnt find the right way to make this happen.
tks

Hi Mario
This is explained in the soa developer's guide. Chapter 43 "Enterprise message source"should help you. You will find how to connect OEMS or JMS in-memory/file based to your BAM data objects with or without xpath transformation.
You can find sample of advanced XML formating in the 10g tech note: "Oracle BAM 10.1.3 configuration for BPEL 10.1.2 using JMS sensors" (useful even if you don't plan to use BPEL).
Anyway, if you plan to use BPEL, forget JMS and use the BAM adapter (chapter 42), it's quicker & easier.
