Application Express API

Guys, sorry for silly question. I'm sort of stuck. How can I access APEX API's packages? I mean where they are?

In the apex editor, If you look in the "Application Express User's Guide" (i.e. the "help" section), there is a chapter headed "Oracle Application Express APIs". For the absolute avoidance of doubt, the user guide can be found at very top right-hand corner of the apex development page, next to the "logout" button - its labelled "Help" (rather aptly, I think).
As a more general point (i.e. not specifically you), everyone should browse through this or, even better, run through the 2 day developer course, before coming near the forum - it would save everyone a lot of grief in the long run! :-)

Print a report from Application Express direct to a CUPS Printer

Hi all, I'm new to this technology, is it possible to print a report from Application Express directly to a CUPS Printer? Can someone tell me in laymans terms how to do it? I find the terminology and documentation less than helpful.

Jeremy,
BI Publisher handles submitting reports directly to a CUPS printer. However, the APEX integration doesn't currently integrate with that portion of BI Publisher.
Here's an options:
Use the Java API of BI Publisher to build a custom Java program that would do this for you. Delivering to CUPS is part of the Java API.

Check Box Bug in Application Express 4.0.2.00.06

Hi All
I was wondering if someone can help me with checkboxes, I'm trying to implement in the report.
I was following Oracle instruction, but it does not work in my application, for some reason.
First Issue:
If I add in a query report the following line apex_item.checkbox(1,attachment_id) del, in the report display as *<input type="checkbox" name="f01" value="48" />* and not the checkbox item.
However, I can overcome this problem by going into the region report and in display change as simple checkbox.
Second Issue
When I check any of checkboxes and click on delete button, I'm getting the following error.
Not found
The requested URL /apex/wwv_flow.accept was not found on this server
I'm using Application Express 4.0.2.00.06
Any ideas why this is happening?
Any sugestions are welcome
Please help me
Thanks in advance.

I'm getting a very strange error using the API for APEX_ITEM as well on Application Express 4.0.2.00.07
select APEX_ITEM.checkbox (1, style_color) as "Selection", image,item,sizes,available_date, price, suggested_retail, Percent_Savings
from sav_tab
This is a table.
There are NO where conditions.
The on_submit process updates a page item :p3_selected with the checkbox contents:
declare
v_select varchar2(4000);
begin
:P3_SELECTED :='';
FOR I in 1..APEX_APPLICATION.G_F01.COUNT LOOP
if APEX_APPLICATION.G_F01(i) is not null then
:P3_SELECTED := :P3_SELECTED ||(APEX_APPLICATION.G_F01(i))||',';
end if;
END LOOP;
end;
It was returning: item,item,item
all of a sudden, it's now it's returning item, column4 contents from the whole page.
What the heck!!!!!
Edited by: Canucklehead on Mar 15, 2011 2:16 PM
I was able to get this working again, by using a different field:
APEX_ITEM.checkbox (5, style_color) and G_F05

How to stop and start only the process of Oracle Application Express?

I'd like to know how to stop the process of Oracle Application Express on my server installed oracle express package.
After installed Oracle Express edition, not only oracle database server processes but also Oracle Application Express, such as http server, is started automatically...
I hope to stop and start Application Express on demand but is this feature enabled?

Oracle Apex is an API, if that helps you understand / visualize. You do not start Apex process nor stop it.
When an Apex session starts it starts calling the API.
You can however start / stop the listener. It may be OHS, ApexListener and the J2EE container running it, OC4J or any other "server" that you are using.
The built-in EPG is something like an API again, you cannot start / stop it but you can disable/enable it with DBMS_XDB.SETHTTPPORT API.

Oracle Pl/Sql and Oracle Application Express for Beginners

Good day,
Have a prodigy that is strongly interested in oracle application express.Haven know that he will only do we in APEX if he is good in pl/sql and have some skills in html and javascripts.
For such person,what are the books that i can recommend for him,that will guide and assist him?Will be highly grateful if anybody can assist.

Sc0tt wrote:
I think it also falsely gives the impression that one does not need to understand the database at all because Apex can do everything for you...This is why I echo Munky when he says that you need a solid understanding of data models and the database before attempting to build an application.
I absolutely concur with this view. When I first started using ApEx, I was basically given a user guide and told to get on with it :-) Subsequently, for the first 6 months or so, I built probably fairly lousy (but functional) apps until I got a better grasp of Oracle architecture.
That being said, SQL is an absolute must if you are going to work on a database. PL/SQL really should be learned as well because your application will be limited without it. CSS and Javascript and nice to have's, but they can be learned as you go. Since all of the api's are built in pl/sql, it would really hinder what you could do if you didn't know it.One resource I have found very useful is the good old 'Ant' book a.k.a. Oracle PL/SQL Programming by Feuerstein, et al. I have a well-thumbed 4th edition sitting on my desk at the moment - weirdly for a text book, rather a joy to read.
I personally found Jay-Lew's "Cost-based Oracle Fundamentals" a somewhat bitterer pill to swallow - tough on the way down but good for one's constitution!

How to Create application express items like text box dynamically

Hi all,
I have a requirement in that i have to create a template like the one in Application express for creating the region and items.
The main requirement is to reduce the amount of time spend in creating the items on htmldb page..
So we are planning of creating a template where the developer at one shot will be able to define all the items used in the the page..So this reduce the amount of time taken in creating and defining each and every item .
Developer use this template which conisist of some 100 text box which act as label for the item which we want to create on the page and there will be check box which show all the item available in htmldb like textbox, check box, select list etc. So developer will check the item he/she want to create and and set properties of it .So this is the single process for creating all the template on the page.
Ones the template is submitted it will create the items on the page ...in a single click..
Please do reply me with ur comments
Thanks

Hi,
I wanted to do similar thing as well. I wanted to add a text field when user clicks a link or button. I was thinking about java script, but not sure how to add the text field items from outside the wizrdy things in APEX!! Possibly using the htmldb_item api, but have not worked out how yet.

Can not login to Oracle Application Express after upgrade to 3.2

I installed oracle database express and then I upgrade APEX to 3.2 on it. I got the login page but I can not login by using any account, like SYS, SYSTEM. From the document, internal ADMIN account should exist but I did not see it from dba_users table.
Thanks,
Julie

HI Don,
I did run apxchpwd.sql to change the Application Express ADMIN user password. Then I invoked http://mymachine:8080/apex and got the Application Express login page. I put ADMIN in workspace and ADMIN in Username and the new password. But I still cannot login. I also tried http://mymachine:8080/apex/apex_admin page login. I typed ADMIN as username and the new password. Then I clicked on Login button. Nothing happened. No error message.
Any idea?
By the way, what does apxxepwd.sql do?
Thanks,
Julie

Unfortunately I can't provide much help, other than that we have seen this before with 9iR2, but haven't yet figured out when this does occur, so not sure if it's related to a specific patch version. If possible, I'd recommend upgrading to database 10g or higher. And if we do figure out under what circumstances this problem comes up in 9iR2, I'll post this on the forum.

SSO Authentication for more than one application in Application Express

Hello,
I recently got a single application working with SSO integration for Application Express 2.2.
Now I would like to create multiple applications within the same workspace, which all use SSO authentication. I tried both copying the working one from the other application and creating a new SSO authentication scheme from scratch into the new aplication.
I cant seem to make the new application work with SSO authentication. Do I have to go through all of the same steps I went through to get it working with the first application?
Thanks
-sean

Ok, my bad.
After shutting down my web browser and reopening it, the SSO integration now works for both the old and new applications. Not sure what was cached, but it was bypassing the sso check.

Upgrading Application Express on Oracle XE (installed on Ubuntu 8.04)

I'd installed on my laptop (OP is Ubuntu 8.04) Oracle XE and is wotking quite fine.
But I really like to upgrade apex to last version (3.1.2). I read documentation but are not many information about how to upgrade.
Daniel

Thanks Arie,
On whatever version of Windows I've updated without problems Application Express.
I'm talking here about Ubuntu (a debian distribution of Linux).
My problem is where to unzip apex, where to use sqlplus command prompt etc., because is different than Windows.
If you don't have DBA rights on the account (user account other than root) you have errors in installation process and more.
For example they say in doc...:0
"To run the apxconf.sql configuration script:
1. Change your working directory to ORACLE_BASE\ORACLE_HOME\apex or whatever convention used to indicate the Oracle home.
2. Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS. For example:
* On Windows:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password
* On UNIX and Linux:
$ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password".....
When you install Oracle what version you need, OP (Linux) create a different user account for Oracle. Usually if you want to use your account like dba for oracle, you need to give to that account the proper rights.
So, I need a installation rutine (for upgrading) for apex on Linux.

Hi Scott
Same results in both IE and FF?
I have only IE
Do you have cookies enabled in the browser?
Yes cookies are enabled in the browser
Does the login page have only two text fields , username and password?
Yes
When you say "no action happen" does that mean you just see the login page all the time or do you see a blank page or something else?
Yes I just see the login page all the time
Thanx
