Website using Oracle APEX

Hi Gurus,
Please tell me if Oracle APEX can be used to deploy a full fledged website on internet.
I have the application ready on my personal machine but need to know if this can be made available for everyone on internet.
Regards,
Abhishek

Abhishek,
If your organization does not have IT infrastructure but has man power (APEX admins), you can use the Amazon EC2 which is cloud computing. Just simply pay monthly fee. Here is a post of APEX on cloud - http://jastraub.blogspot.com/2009/03/test-drive-oracle-application-express.html
Otherwise, here is the list of companies which can host APEX applications - http://www.oracle.com/technology/products/database/application_express/html/apex_com_hosting.html

Can I use Oracle APEX with MySQL Database

Hi All,
We are looking to create a performance dashboard using Oracle APEX for our client, but the application database is MySQL. Is it possible to create reports in APEX using data from MySQL database? If yes, are there any specific steps to be followed or any additional setups needed?
Any inputs would be really helpful.
Appreciate all the help
Thanks,
Sameer

Hi Sameer,
it's not possible to use apex on mysql, as stated above me by several persons.
If you havent got any oracle database in your organization, apex would be an expensive choise unless you use the free Oracle XE (express edition), which has APEX embedded.
There are some limitations to XE but with a bit of smart thinking it wouldnt be much of a problem.
[check the XE information here|http://download.oracle.com/docs/cd/B25329_01/doc/install.102/b25143/toc.htm#BABIECJA]
In short:
- XE will use 1 CPU even if you have two or more in your system
- There is a 4 GB data limit
- RAM memory usage is limited to 1 GB
- 1 installation per computer
You can use XE as a reporting database. This will relieve your mysql database from heavy reporting processes, too.
The XE can be used as a mini data warehouse. So you have to transfer and transform the relevant data from mysql to your XE instance.
After that you can start building report screens etc in the embedded Apex .
hope this helps you

How fetch data from a view(which is located in different server) using Oracle APEX webservices

Hi,
I have a requirement to fetch the view data from client instance(which is different server) to another instance lets say Development instance
Requirement:
Need to get the Apps View data from the Desired EBS instance(which is accessible online) using webservices,and display it in the Oracle Apex Development Instance.
Kindly provide your inputs how to achieve this.
Thanks in advance

Are you getting an error? The way you have it set up, you can have an error and it will never be displayed. Put and error control on your front panel and see what it gives you. Also, shared variables in a project can be useful. Look at some examples for that.

Need help in creating Aria using Oracle APEX

Hi,
I am trying to develop an employee lookup using DBCON's PDF(http://www.dbcon.com/oracle_apex_ebook_aria.html).
I downloaded the Oracle XE, version 11.0.0.28844 and used the APEX from this. But, the files provided by DBCON seem to be old. I tried using the AriaTheme.sql file in the APEX, but, it errors out complaining that the file is not compatible.
As this did not work, I downloaded the APEX(apex_4.0.1) and am trying to proceed with this. This comes with a large package and it is not clear on how to install and where to start off to build ARIA.
Please help me out with the latest compatible theme or suggest the XE version that I need to download.
Thanks,
Divya.

I downloaded it from: http://www.oracle.com/technetwork/database/express-edition/downloads/102xewinsoft-090667.html(Oracle Database 10g Express Edition (Universal) )
Could you please comment on the 'Aria' setup, if you are aware?

Hi All ,need ideas on using oracle apex maps...

Hi All,
I need a map on country like trinidad and Tobago and jamaica together how do I accomplish that...using the current oracle apex..
I couldnt find country tobaga and Trinidad listed there
Thanks any guidance shall be appreciated..
Paul j

Hi Paul,
There actually isn't a country map for Jamaica or Trinidad and Tobago in the suite of AnyChart maps that we integrate into Application Express. Your easiest option is to use either the World, Americas or North America map - either of these will allow you to represent Jamaica and Trinidad & Tobago on a map, and associate data with it. I've used the Americas map as an example here: http://apex.oracle.com/pls/apex/f?p=36648:89.
I appreciate that this isn't ideal if you wish to represent these locations on their respective country maps, but it might be a possible workaround for you. Alternatively, you would need to source your own Shapefiles for these countries, and use the AnyChart Flash Map Converter utility - http://anychart.com/products/anymap/converter/ - to convert your Shapefile into a .amap file. That .amap file would then need to be incorporated in your APEX /images directory, and its information would then need to be referenced in your map SQL query in order to associate data with the new maps. For further information on the Converter utility, or indeed on the AnyChart maps, please refer to the AnyChart site: http://anychart.com/products/anymap/docs/.

How to use Oracle APEX with Oracle12c - Beginner

Hi. I have been using for months Oracle Application Express thanks to the online workspace on https://apex.oracle.com/i/index.html.
Now, I want to create my production environment. I have installed Oracle Database 12c on a virtual machine (Oracle Virtual Box) based on Windows Server 2008 R2 (64 bit) o.s.
I have created a new database and, during this process, I have selected only "Oracle Application Express" as database's option. Now, I don't know how to use APEX, how to configure the Listener and whatever I need to let the users may use my APEX's applications. Thank you very much for any help. Please consider that I am a beginner and I don't know how to master the administrative-side of APEX.

Issue while adding WCF Web Service reference using Oracle APEX

Hi,
We have an issue with creating the Web Service Reference for the WCF web service:
http://dev.virtualearth.net/webservices/v1/metadata/geocodeservice/GeocodeService1.wsdl
The APEX gives the following error
“The WSDL document could not be understood by the rendering engine. Click Create Web Service Reference Manually to continue creating a reference for this service.”
Can you please tell me if creating the Web Service Reference for WCF is supported on the “out of the box“ APEX?
Environment information:
APEX 4.0.2.00.07
Database 11.2.0.3
Please note that we have tried it in APEX 4.1.1 from apex.oracle.com and the error there is different, it can connect even to ASMX wsdl.
Thank you.

I don't think that is it specific to just .NET web services. I have tried with a web service created with TIBCO BusinessWorks (Middleware product) that did not work either. The wsdl validated correctly in soapUI, so I think it just must be the implementation of the parser which is looking for some specific format.
When in doubt, go with either the manual reference or with pl/sql using one of the api's.

How to print a BLOB (image) on a PDF report using Oracle APEX Listener as Print Server

Hi,
I use APEX 4.2.
I have the following query as SQL text for a Report Queries in Shared Components:
select
    customer_id,
    cust_first_name,
    cust_last_name,
    cust_street_address1,
    cust_street_address2,
    cust_city,
    cust_state,
    cust_postal_code,
    phone_number1,
    phone_number2,
    credit_limit,
    cust_email,
    filename,
    company_profile,
    -- customer_image,
    decode(nvl(dbms_lob.getlength(customer_image),0),0,null,
    '<img style="border: 4px solid #CCC; -moz-border-radius: 4px; -webkit-border-radius: 4px;" '||
    'src="' ||
    apex_util.get_blob_file_src('P22_CUSTOMER_IMAGE', customer_id) ||
    '" height="75" width="75" alt="Photo Customer" title="Photo Customer" />') customer_image,
    mimetype,
    image_last_update
from
    demo_customers;
I am unable to have the image printed on the PDF report. Even when the P22_CUSTOMER_IMAGE is defined as session state item.
Does someone knows how to print such image/BLOB in a PDF report?
Thanks by advance.
Kind Regards.

Hi,
Indeed, I would need a custom layout.
Unfortunately, it seems (according to this white paper) not possible with the APEX listener only. I would need a third pary tool. A pity...
For me strange, that I cannot generate such a report having images or pictures in a pre-definied report layout... Maybe a future enahancement for Oracle.
Kind Regards.

How to use oracle APEX with an distant database located on a distant server

Hi there,
I'm a brand new user with Oracle Technologies. I've installed ORACLE 10g XE and updated APEX to 4.0 version on my laptop.
My Manager has setup a distant server with a Linux Red Hat. He has installed on this server EBS R12 with a 11i database.
As a training, I'd like to play with the tables located on the server with the APEX 4.0 installed on my laptop.
As the server is on the same local network and following the description above, is it possible to plug my local APEX to the server database ?
If not, does it mean I have to install APEX on the 11i server database and then connect to the server to play with those tables ?
Thanks a lot for your time and support ACEs members.
Regards,
Ulrich

Hi Ulrich,
yes, you can access other database from your APEX database. The mechanism used to do this is called a "database link". You need to create such a database link in your local database, then you can access the remote database like this:
SELECT *
FROM databaselink@EMP
;If you want to use such remote objects from within APEX you need to create local views to wrap this (search the forum for apex and database links, you'll find interesting threads).

Create PDF from PL/SQL-Interface XML FOP / Oracle BI / Oracle APEX packages

Hi All,
I think this is perhaps the most often asked question. And people suggest using PL-FPDF or PL PDF. There is a constraint, I can't use PL PDF because of monetary reasons.
I wish I could use some method to output PDF from the PL/SQL. I already have a document (word document stored as CLOB). Now, I need to output this file as PDF. I know doing this outside database is easy and advisable, but this what I have been asked to do.
Is there any method of implementation, using either XML - FOP or Oracle BI publisher or Oracle APEX tools (and not Oracle APEX itself, I know how to do this if the application is built, run using Oracle APEX, but this is plain Oracle HTP).
Database: Oracle 9.2 running in Windows server.
Thanks in advance.

Apologies for that.
I am looking into ways to use Apex. Like calling the FOP in Oracle OC4J server and generating PDF from it. As I told already, we have this application built on Oracle HTP, we can't move to Oracle Apex now. I can install Oracle APEX and use the tools it offers. No problem in that.
PL-FPDF is free, but I can see this doesn't help much. What I have is CLOB, not data from table. :(
I am just looking into different ways one can do this.

Digital Certificates and Web Services with Oracle APEX

Hi people,
I am working to implement Web Service communication using Oracle Apex. I need to create an application that calls an external public Web Service in Apex. So far, so good, and i am able to work with a public WS without any problems.
However, this particular WS I'm calling has two peculiarities:
1) It is SSL-Secured (HTTPS). This means i have to communicate using SSL and Public/Private Certificates.
2) The message i pass (payload) must be digitally signed using XMLDsig Standard (www.w3.org/TR/xmldsig-core/)
The first requirement i am still testing, but it will probably work if i import the public and private keys using Oracle Wallet and point to this Wallet, just as PayPal sample in OTN samples does, don't you think? Should i have any problems with this?
The second one is more complicated, all APIs i have seen for XML Digital Signing are Java-based or .NET-based, i have found nothing based in PL/SQL packages or such. Can you point me some other options to sign this XML?
Please bear in mind that, since the WS has more than one method, i am using plain old UTL_HTTP to call it (just like the PayPal sample in OTN). PayPal requests that all communication be SSL-enabled, but has no mention whatsoever for Digital Signatures.
Can anybody help me out with this? any help is highly appreciated.
Regards
Thiago

Thiago:
You are correct in that there should be no problem interacting with a Web service that has an HTTPS endpoint as long as you create a wallet and specify it when you make your UTL_HTTP calls, like the PayPal example.
I am not aware of a PL/SQL utility to create a XMLDsig Standard message, but if you find some Java source out there that does it, you may be able to follow a technique I used for a similar use case:

Reading and Updating MS Active Directory (AD) through Oracle APEX

Hi All,
Has anyone ever read and update the AD components using Oracle APEX?
I know we can have APEX build in LDAP Authentication, but that is for the Authentication, what about reading other attributes like phone no., department, office etc. from MS AD; and about updating the same information.
Is Oracle Identity Management the only solution?
Windows 2008 R2 Server provide SOAP based AD web services (ADWS), has anyone used that with APEX (11g R2 with EPG configuration)?
Is it possible to have a C# code (through external procedure) which could read and write MS AD; can we use only "C" code in oracle as external proc or C# as well?
Any pointers would be of great help.
Thanks,
Ash

Ash,
It's possible to query data from the LDAP server, but it's not as easy as you'd like. I don't know about updating, but fopr querying, you're looking at creating a package using DBMS_LDAP and a pipelined function to get the data. Here's one example from a quick google search; there are others.
One thing to be aware of that burned me: the default LDAP setting limits requests to 1,000 records. If your search gives more than that, you get an error (and no data at all). So you may find yourself having to use unions to get the full data, which slows things down a bit.

-- Send plain text email
APEX_MAIL.SEND(
    P_TO       => '[email protected]',
    P_FROM     => '[email protected]',
    P_CC       => '[email protected]',

Please suggest me how to fix this issue.
Thanks
Sudhir

Hi Mike,
Thanks for your reply, Let me give you a detail on where we are stuck on send mail.
   We have a Schema called PORTAL
We are able to send mail from UTL_SMTP as mentioned below in a procedure
create or replace PROCEDURE send_mail (p_to        IN VARCHAR2,
                                       p_from      IN VARCHAR2,
                                       p_message   IN VARCHAR2,
                                       p_smtp_host IN VARCHAR2,
                                       p_smtp_port IN NUMBER DEFAULT 25)
AS
l_mail_conn   UTL_SMTP.connection;
BEGIN
l_mail_conn := UTL_SMTP.open_connection(p_smtp_host, p_smtp_port);
UTL_SMTP.helo(l_mail_conn, p_smtp_host);
UTL_SMTP.mail(l_mail_conn, p_from);
UTL_SMTP.rcpt(l_mail_conn, p_to);
UTL_SMTP.data(l_mail_conn, p_message || UTL_TCP.crlf || UTL_TCP.crlf);
UTL_SMTP.quit(l_mail_conn);
END;
Begin
send_mail('[email protected]','[email protected]','test','10.0.0.100','25');
End;
The above code works i am able to send and receive mails.
We also create ACL as mentioned below
begin
dbms_network_acl_admin.create_acl (
acl => 'http_permission.xml', -- or any other name
description => 'HTTP Access',
principal => 'APEX_040100', -- the user name trying to access the network resource
is_grant => TRUE,
privilege => 'connect',
start_date => null,
end_date => null
end;
commit;
SELECT * FROM dba_network_acl_privileges where principal='APEX_040100';
begin
DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(acl => 'http_permission.xml',
principal => 'APEX_040100',
is_grant => true,
privilege => 'connect');
end;
commit;
begin
DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(acl => 'http_permission.xml',
principal => 'APEX_040100',
is_grant => true,
privilege => 'resolve');
end;
commit;
BEGIN
dbms_network_acl_admin.assign_acl (
acl => 'http_permission.xml',
host => '10.1.1.100', /*can be computer name or IP , wildcards are accepted as well for example - '*.us.oracle.com'*/
lower_port => 80,
upper_port => 80
END;
But still we are getting same ACL Error Please suggest US
ORA-24247: network access denied by access control list (ACL)
Thanks
