File Browse Upload Feature for Apex

Hi,
I added the File Browse feature to my Apex page. However I would like to customize the file to be uploaded into a different database as a BLOB. Any examples? Thanks.

Jacky,
Looks like you asked the same question here: File Upload to Custom Table
Please refrain from double-posting.

File browse/upload explanation

Hi,
I have seen the howto about the file upload appliation that's written for 1.5. <http://www.oracle.com/technology/products/database/htmldb/howtos/howto_file_upload.html> I do understand it reads the selected file into some default table and that it get's some ID that should be used to reference it. What is the recommended way to move such a file to a user table ?
Will the howto be rewritten for htmldb 1.6 ?
thanks,
Ronald.

Hello,
The screenshots and instructions on where to click should be updated but the code will remain the same. There's a section in the How To which talk about moving the BLOB to a custom table look for "Store the Document in a Custom Table"

Flat file data upload - happens for only 1 column

Dear Experts,
Goal: To upload data from flat file (with 3 columns-char3,language,text) to characteristic (texts).
Problem: I am doing through CSV File but when i click on preview i am able to see data only in first column, the other two columns are empty.
More details:
I have created this data source in data source tab.
Adapter - Load text type file from Workstation.
data format -Seperated with seperator (CSV).
Data Separator     - ,
Escape Sign     - "
File name      - C:\Documents and Settings\hans\Desktop\mtype.txt
Fields
/BIC/TSMOVTYPE           CHAR     3
LANGU               CHAR     2
TXTSH               CHAR     20
Can anyone give me idea?
regards
BI Learner

Hi,
You can try this:
1. After ESCAPE SIGN, there will be an option " Number of rows to be left". Put 1 there.
2. In your flat file, leave the 1st row blank or add anything in the first row for all the three columns.Save as CSV file. Note that the file must have the same sequence as in the data source.
3. Check your transformations. Data source fields should be mapped correctly to the right side.
try to load now. Hope it'll help.

Best browser to develop for ApEx, Firefox or Internet Explorer

Greetings!
I have a simple question, which is the best web browser for doing Oracle ApEx (Applications Express)? I already know the answer, Firefox, but Firefox is blacklisted by my current employer.
My primary reason for asking such a question is to help me make a case to my company internet security officers to allow Firefox to be installed on the work stations of the ApEx developers. Currently, we are restricted to using Internet Explorer (IE 6.x) only.
The security of Firefox has been sited for not allowing it's installation or use on any computers on our corporate network. There are some who believe that IE 6.x is more secure that Firefox 3.x.
My expertise as a seasoned ApEx developer who has used both and has become a better and more efficient developer since using Firefox along with the Firebug plug-in. Firefox and Firebug allow a JavaScript debugging that is far superior to JavaScript debugging utility that is available for IE 6.x.
Please make any suggestions that may help me to present a compelling argument for allowing Firefox to be allowed on the systems of the ApEx development team members.
Thanks,
Charles

Hello Charles,
Seems you have all the right information and arguments at hand:

Ask these people to support their believe by evidence.

File Browse Item in APEX versions prior 4

Hi there,
we are currently struggling with a strange issue concerning the File Browse Item in earlier APEX versions: The item value is not submitted correctly when using APEX Listener. There is always a F<randomnumber>/ as prefix that is not visible anywhere in the page source code (so it's not generated by APEX itself) or browser (Firebug trace didn't see any prefix transmitted) and this value is even there when the file browse dialogue is submitted empty. The latter case causes severe problems, as validations fail to detect null values. Our current workaround is a regex on that prefix, but this obviously is no clean solution.
We found out that F<randomnumber>/ is the prefix of the name that is created temporarily in WWV_FLOW_FILES. If submitted correctly, the name is prefix + actual filename.
This problem does not occur when using OHS and it does not occur when running the APEX Listener on top of APEX 4.0.2.
The problem occurs reproducible in the following environments:
- APEX Listener 1.1.2 standalone or any JEE Container, JDK 1.6.0_26, Linux or Windows
- APEX 3.1.2 or APEX 3.2.1
The problem seems to be related to the one discussed in {thread:id=2205973}, but describes some different effect that is not reproducible on OHS.
I appreciate every clue where this may come from and any hint on how to turn it off...
Thanks,
Udo

Hello Claudio,
After reading this story, I have same problem with version 1.1 of the apex listener and version 4.1 application express.I still think it affects only versions prior to 4.0. I'm not able to reproduce it on 4.1.
How do I resolve this problem?I think you ran into a bug in GlassFish 3.1.2. This has been discussed and resolved here: {thread:id=2357381}
I hope this helps you solve your problem.

P.S.: Please always open a new thread if you are not sure you are in the same situation and especially when the original thread is long "dead" like this one. Of course you can reference other threads with possibly similar issues in your thread.
Thanks!

File Browser always clears

When I pass a string to a File Browse item from one page to another, and then back, my file browse object is empty, even though the application appears to know its value.
In this example, I've shown how I'm debugging my code.
http://i37.tinypic.com/18epkz.gif
In this picture I show the results.
http://i34.tinypic.com/11glug3.gif
And this shows the value of the session variables.
http://i36.tinypic.com/jacgnn.gif
Why doesn't the file browse item display?
Thanks,
-Ken

Hello Ken,
Scott is right. The HTML standard, and the way it's being implemented in the browsers, put some security restriction over this item type. This behavior has nothing to do with APEX. For example, you also can’t set a default value to this item, and the browser will always clear it upon submit.
Also, if you’ll look at the value of the item, as the system “see” it, you’ll see that it’s not exactly in a valid format for the File Browse item. The APEX engine prefixes the file name with an internal ID number, as part of the loading process. In this state, this value is useless as a file brows value.
BTW, interesting debugging technique.
Regards,
Arie.

File Browse Item translation

Hello all,
I would like to ask if is possible to translate the "Browse..." button of File Browse item.
For me it seems that the button cannot be translated to a different language. I have tried to export the XLIFF and there is no string like "Browse...", also I have tried to edit it manually in translation repository, but the string is not present here.
Any ideas?
-Jiri

I think it is decided by the browser itself according to the browser lang

As noted, this confuses the issue, since a possible answer was posted in the OTHER thread.. Check your server logs, you are probably timing out.. From prior threads with a similar issue:
Have a look at the httpd.conf file (or get your system administrator to look at it) and see what the value of TimeOut is set to. You may need to increase it in order to export large tables via APEX.

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?

Where's JDeveloper11g file browsing feature for codes?

In JDeveloper 11g, whenever I type img src, followed by an equation sign, I expect to see the File Browse link being popped up along with all the files within the directory so I can easily pick the ones I need. Unfortunately, this function does not work, and all I get is "CDATA or ELExpression" being popped up which usually happens when there is no code insight. I am sure the File Browse and easy pick feature did exist before way back in the early versions of 10g. Is this a bug in 11g or it is a step backward by removing that feature although I don't believe there's a sound reason to.

Hi, I'm afraid I have got this issue since the first clean install. For all 11g versions I have tried on, there is no popup for File Browse, as you can see here:
http://s8.postimg.org/4wy23u6ut/image.jpg (Jdeveloper 11g)
On the other hand, when I checked the old 10g version that I have previously, it has that, just like below.
http://s21.postimg.org/aetyo97mr/image.jpg (JDeveloper 10g)
For all the above, I am using JSP page. Usually I would create a custom application, and then adding a new JSP. I believe this shouldn't result any peculiarity, as it's almost standard procedure.
Update: I think I've figured out. I didn't have image files in the directory yet. After I have put some images in the directory, I'm now able to see the File Browse.
By the way, is JDeveloper 11g short of support for inline CSS parameters?
For instance, if i type the HTML, [anchor] input style [equals], it doesn't pop up things like 'text-align' etc. I think I noticed this feature when I'm doing a preview of 12c, so can anyone confirm that this doesn't exist in any version of 11g?

Possible to set the Created_by column value for File Browse?

I'm using database account authentication and then a user gets to upload a file. Then my stored procedure reads the file. I was investigating a problem, happened to search the apex_workspace_files view and noticed the created_by column is always set to APEX_PUBLIC_USER for the files my users upload. Is there some way I can set that value when they log in, so I can track who actually did the upload?
Thanks,
Stew

Dimitri,
I was just using the standard File Browse item, so getting the blob from the workspace view. Though I've seen notes here about loading to your own table, what I had seemed to work (and was done) fairly well. There were just these little features I wanted to use...
Thanks for the suggestion.
Dave, I'm not sure which stored procedure you're suggesting I add the apex_custom_auth.get_username value to? I hoped that the internal File Browse routine would pick up the get_username value automatically instead of the application definition Public User value.
Thanks,
Stew

Open Cursor Issue because of file browse Item - Is this a Bug in APEX 3.2

Hi All,
I am using file browse Item to upload file into the database at two places in my application, but it seems whenever I am submitting those two pages, with file path or without file path, its opening an cursor which remains open after that, because of this open cursor count in the application is getting exceeding every time.
For testing this I have made an dummy page containing just file browse item and submit button, and still it is increasing the open cursor count.
Is this a bug in Apex file browse item or there is some other way to handle this.
Please kindly help me in the above issue as this is affecting the production application.
Thanks & Regards
Sanjay

Hi,
One observation, Apex is switching the Session ID after one got killed ? I was working on Apex page with browse Item to test open cursor count,
after killing the SID (227) on which the open cursor count was getting increase, it APEX automatically switches to new SID(149) for that session.
Now the problem is even if I have two SID's and one hits the maximum open cursor count, It is not switching to other SID instead the whole application becomes unavailable.
STATNAME SID VALUE USER
opened cursors current 20 14 APEX_PUBLIC_USER
opened cursors current 149 74 APEX_PUBLIC_USER
opened cursors current 194 71 APEX_PUBLIC_USER
opened cursors current 211 5 APEX_PUBLIC_USER
opened cursors current 227 325 APEX_PUBLIC_USER Killed
opened cursors current 244 15 APEX_PUBLIC_USER
opened cursors current 20 14 APEX_PUBLIC_USER
opened cursors current 149 76 APEX_PUBLIC_USER
opened cursors current 194 71 APEX_PUBLIC_USER
opened cursors current 211 5 APEX_PUBLIC_USER
opened cursors current 244 15 APEX_PUBLIC_USER
Please kindly help in this.
Thanks in Advance

I have a file browse item which uploads a file into the built in WWV_FLOW_FILES. The problem is it uploads even when there is an error and my validation flags up. Is it supposed to...Yes. The file data is just the same as any other form value, and has to be submitted and held in session state (in this case in <tt>APEX_APPLICATION_FILES</tt>) before APEX can do anything with it:
{thread:id=902770}
Basically I dont want the end user to upload the same file more than once.You'll have to perform some kind of validation check for this and if it fails, delete the unwanted file:
