3.1 EA3: Application Express Export/Quick DDL fails

I've tried all of the options to create DDL for applications under the Connections > Application Express menu but I keep getting a blank sheet as the output.
Using the export option (on either pages or application level), it results in a file with the export header only (file created - Date).
There are similar results with the quick DDL options.
I am using Apex 4.0.1 if this helps.

I have filed bug and the problem is fixed for our next release. Thanks.

[4.0] Incomplete sort for objects in DDL when using Database Export or "quick DDL"

As far as I could see, a similar problem has been reported for earlier versions of SQL Developer, but still seems to apply for some parts in 4.0.0.13.80 under Windows7 64bit with JDK 1.7.0_45 64bit ...
Currently not all objects in a generated DDL using "Quick DDL" or "Tools - Database Export" are sorted evenly ... tables and foreign key constraints seem to be sorted, but common constraints are not.
This is rather annoying when trying to compare the generated scripts of two databases. Or trying to detect changes over lifetime (SVN etc.).
Or is there an option for this I could not find/see so far?
example output from database export of SQLDev 4.0.0.13.80 on the same machine, within some minutes, no configuration change, for a local and a remote database ...
from local:
Questions:
why are there blank lines added for the local database
why aren't the grants in the same order
local database
remote database
GRANT DELETE, INSERT, SELECT, UPDATE ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "ACCESS_ROLE_FOR_SCHEMA_3";
GRANT REFERENCES ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "SCHEMA_3";
GRANT REFERENCES ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "SCHEMA_4";
GRANT SELECT, REFERENCES ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "SCHEMA_5";
GRANT SELECT, REFERENCES ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "SCHEMA_6";
GRANT SELECT ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "SCHEMA_7";
GRANT REFERENCES ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "SCHEMA_3";
GRANT REFERENCES ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "SCHEMA_4";
GRANT SELECT, REFERENCES ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "SCHEMA_5";
GRANT DELETE, INSERT, SELECT, UPDATE ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "ACCESS_ROLE_FOR_SCHEMA_3";
GRANT SELECT, REFERENCES ON "FOREIGNSCHEMA"."TABLE_FOR_GRANT" TO "SCHEMA_6";
remark: missing SCHEMA_7 is okay, because it is not yet on the remote database
Similar applies to non foreign key constraints, where the unsorted output is even worse ...

Did you ever figure out why SQL Developer isn't exporting the NOT NULL attribute of columns?
I'm running into that on a 9i database, but not on 11g.

Can't use Final Cut Express Export Using Quick Time Conversion with iDVD.

I am using iDVD 08v 7.0.4 and until 3 days ago I could import and create iDVD's using Final Cut Express export using Quick Time Conversion. There was an update that downloaded for iDVD. Since then, I can only use Final Cut Express Exports that is a self contained Quick Time Movie.
I have never had this kind of apple and apple problem. I am disappointed that I'm having apple issues like this.

Are you on latest 10.5.x release and latest FCE updates? Your info line says 10.5.1 and you didn't list FCE version. Not saying that will fix problem, but might help. You also might want to explain how you did your Quicktime conversion.

Version Control for Application Express

Hi all,
We are using Application Express (HTML-DB) 2.0 with Oracle 10g Release 2. We have developed a number of pages within our application (basically sales reporting). We are starting to get ready move these pages to a test and production environment.
Before we move to a production environment we need to implement a version control and migration (development -> test -> production) system. I have read various posts about importing and exporting pages and applications that have been very informational. However, I am still not clear on certain areas, any help/information on the below questions/comments would be helpful.
1.     How are other people implementing version control? For some of our other environments (for example, PeopleSoft-SQR) we use Visual Source Safe. Can we use this along with Application Express or is there a way to keep track of versions within Application Express it self?
2.     I see you can view a pages history at Home>Application Builder>Application 107>Page Definition>History. Is there a way to view the differences between the pages or to revert back to an older page?
3.     I know you can export a single page but that leaves shared components behind that might leave the complex page in a non-working state if imported and installed in the production application. Is there a way export and import shared components, for example LOVs?
These are a few of the questions I havebut I thought it would be a good place to start.
Here are a couple of links that have given me some information related to the topic.

Version Control
How do people version control HTML DB applications?
I would be interested in hearing your thoughts and ideas on this topic.
Thanks,
Stuff

Stuff - this is also something we've been grappling with.
Did you see the excellent tip about using Web server (or PL/SQL) redirects to point to the current app? The idea is that you copy the current prod app, work on the copy and then update the redirect to point to the new app when it's released and make the old app unavailable.
This is quite brilliant in its simplicity, and has the added benefit of leaving the old app intact for bug fixes and re-releases, (or even rollback) if necessary. However, the problem with it, and the reason it's no good for our purposes, is because it sits on top of the same schema, so if the version control applies to objects in the database (i.e. the schema itself or packages etc.), then you're snookered (as far as I understand it anyway).
In a previous project, our suppliers used VSS and versioned code at the app and function/procedure/package level - I'd love to know if anyone has a robust scheme for versioning at page level.
I suspect History is an audit trail rather than versioning - I can't imagine that all the objects in all their respective states are being persisted for anything other than 'undo' purposes.
Versioning at page level seems to be problematic but it can be done, provided that the shared components are sufficiently consistent. The trick is to edit the security group ID, but the usual caveats apply.
What seems problematic to us is how to create a build out of components at different versions, like you might in a conventionally-packaged exe. I think we might end up checking in (or just saving in the file system) consistent versions at app and package level (having developed and tested in a separate schema or instance), and doing an overwrite of the prod app plus running a DDL script for package/function/procedure updates with schema deltas and other things like image uploads applied manually at cutover.
I suspect that once I delve a bit deeper into where all these objects are stored, there will be more potential for scripting, but I'm not entirely confident that this will, reliably, give us entirely what we had in Pre-Prod. Another problem I've found with this approach is that packages don't get consistently replaced.
It may simply be that we're applying waterfall concepts to what is really a RAD tool, but in any case this is my first Web-enabled development so I've been at sea with everything from design methodology to version control.
Like you, I would be really interested to hear of other suggestions.
Regards,
John.

Application Express and Version Control

We are using Clear Case for our versioning. We are looking at Application Express for our simple screens(rest is in java/struts). Our only concern with application express is integrating it into our current version control methods.
How much effort is involved in exporting the schemas and checking them into clear case?
also, we will have multiple people developing html db forms. How complicated does this integration get?

Hi User....
My team uses Microsoft Source Safe for version APEX control.
We export the Application as well and the schema DDL to text files and then check them into SourceSafe. We carefully label the check-ins with appropriate version numbers. The version numbers are also added to Page 0 so we know what version we are running. This work reasonably well in APEX 2.0. I believe that it will be even easier in APEX 2.2.
If you have multiple developers working on a single APEX application, create a special user ID that is used for only locking pages. This trick prevents your developers from making accidental changes to a perfectly debugged page. The locking ID is under the control of the project manager or the team lead. It is also handy for controlling the check-in-out process for individual pages or groups of pages.
I hope this helps.
Cheers,
Patrick Cimolini

Code 128 Barcode printed from Application Express

Hi,
My colleague and I have written a procedure to generate Code128 Barcodes. These appear fine on the screen within Application Express 3. But when we export the file as an RTF or PDF document to our BI_Publisher server running under LINUX RedHat the Barcodes are greyed out and cannot be seen.
Anyone any ideas on how to solve this? It is extremely irritating only to be able to offer our users the ability to print the Application Express page off rather than a proper document.
Thanks

Hi kcbemssr,
I don't know weather you can see this reply, but i still want to say something about this.
Did you used another type of code 128?
you can try this. and here is a site i recommand you, it's all about barcode, you can get code 128

Application import/export failing, hopefully a simple one though

hi all,
i'm very new to oracle and am trying to get going with xe. i'm working between work and home and want to be able to transport wherever i'm at to work/home - so i thought the application import/export function would be the best way? first of all, is it?
if so - i keep getting the
failed to parse SQL query:
ORA-00942: table or view does not exist
error
i'm running the same versions of oracle, on the same platforms (Application Express 2.1.0.00.39, winXPpro all service packed up). both my users have dba roles and the apps work fine on the machines i created them on. the import and install processes claim to be successful and the error only comes up when i try to log in to the application. any ideas?
btw - the apps are just simple tests, dependences etc with a couple rows in each table]
any help be much appreciated even if its "go read this!" as i've googled away & got not much....
cheers!

Your problem is likely that in your office you do not have the tables required by your program. The export does not include your tables. You have to create them yourselves

Problem while importing the application in application express 3.0

Hi Friends
We have developed an application in a workspace say X. I imported the complete application in different workspace Y and the import was successfully. Now if I export a single page from that application in workspace X and import in workspace Y, then it gives me error as
"This page was exported from a different application or from an application in different workspace. Page cannot be installed in this application."
Also I tried changing the application id in the export file but did not work.
Is their a workaround for this?
(We are using application express 3.0.0.00.20)
Thanks
Minakshi

Hi Scott
1 ) Page exports are to be imported into an application having the same ID as the source application in the same named worskpace.
But the problem is I cannot have same application id in the same workspace or in different workspaces even. I exported the complete application from workspace X with application id as 555 and tried importing the application in workspace Y with the same application id. But that does not work since it throws the error message as the same application id cannot reside in 2 different workspaces.
2) You don't say whether workspaces X and Y are in the same or different databases.
Both the workspaces X and Y are in the same database. The database user/schema that is associated with workspaces X and Y are different.
3) Also I tried changing the application id in the export file but did not work.
Following is the extract of the page that i tried importing. The places wherever it is marked BOLD, i modified them in the original page export sql file.
--application/set_environment
prompt APPLICATION 500 - Load_Factor_System
-- Application Export:
-- Application: 500
-- Name: Load_Factor_System
-- Date and Time: 15:52 Wednesday May 16, 2007

-- Version: 3.0.0.00.20
-- SET APPLICATION ID
wwv_flow.g_flow_id := 500;
wwv_flow_api.g_id_offset := 0;

In case you need further clarifications, please let us know.

Importing components to Application Express

When trying to import a component export into Application Express with same app Id and workspace I have problems when I get to the report layouts and report queries.
I get this for some, not all of the report layouts:
Component Export: REPORT LAYOUT 30423319886223781
...report layouts
WWV_FLOW_API.ERR_REPORT_LAYOUT_CREATE ORA-00001: unique constraint
(APEX_030200.WWV_FLOW_REPORT_LAYOUTS_IDX2) violated
but the import continues until it gets to the report queries, I get through 5 and then this:
Component Export: SHARED QUERY 25478002913036435
...shared queries
declare
ERROR at line 1:
ORA-00001: unique constraint (APEX_030200.WWV_FLOW_STORED_QUERIES_UK1) violated
ORA-06512: at "APEX_030200.WWV_FLOW_API", line 6261
ORA-06512: at line 32
then it stops and quits...
Why am I getting this on only certain report layouts and queries??

Hi,
I think you are posting to wrong forum. Virtualization Discussion Forum is here.
Oracle VM Server for x86
Anyway,
There is by default obe workspace. User and password for that workspace is obe
If you need login to APEX administration, then use apxchpwd.sql from oracle user home folder to reset INTERNAL workspace ADMIN user password.

Creating or copying application express users from development environment

Hello,
Hope someone can answer my question soon.
I am kind of new to the application express development and to Oracle database too ( about 8 month). I developed an application on development environment at my work. Now it's time to deploy this application to test and production environment. This application is secured so I had an ACL page were I setup 2 users that they can view and edit data, and I setup myself as an admin for this application.
I succsessfully deployed the application on the test and production environment but I cannot login and not other users. How do I setup or to copy same users from Development to production environment.
I am using apex 3.0.1 and database 10g.
on Development I have workspace called development and the schema is DEV. For production I have a workspace called production and the schema called prod. So I am dealing with different 2 workspaces and 2 different schemas but one database instance.
Thank you in advance for your assistance.
Kind Regards,
Sofia.
Edited by: user633945 on Oct 15, 2008 3:36 PM

Hello,
APEX has a utility to export the workspace and the users. In the application, go to export/import --> export --> workspace users (this is not the default view, and you’ll need to choose it). This will generate a SQL script you can import into the source instance.
In general, it’s best to keep the same environment in the development (test) and production instances – The same workspace ID, name, and application ID. These are pre-condition to be allowed to import single page/components between the instances. Otherwise you will have to import the entire application, each time you need to update the application.
In case you can’t maintain the same environment in your instances, you’ll need to manually edit the exported script. If the workspace already exist, you need to delete the ‘Workspace’ section. Then you’ll need to edit the user details, setting the default schema correctly.
Hope this helps,
Arie.

Oracle Application Express 3.0 and Ajax

Can we build Web 2.0 (ajax) application in Oracle Application Express 3.0?
- Open discussion
- Resources links welcome
Please contribute your thoughts thank you.

Hello,
All the examples in the documentation that he pointed you at are from this application.
It can be downloaded from here and installed.
http://apex.oracle.com/pls/otn/f?p=11933:22
You can also go to individual example pages ans most of them have the relevant code and links back to the forum thread that asked for that particular example.
Here is the overview page for the APEX ajax framework http://apex.oracle.com/pls/otn/f?p=11933:63
and here is the most basic example
http://apex.oracle.com/pls/otn/f?p=11933:11
This sample application has some Ajax features
http://www.oracle.com/technology/products/database/application_express/packaged_apps/packaged_apps.html#DOC_LIB
and these sample code example also take advantage of Ajax.
http://www.oracle.com/technology/products/database/application_express/packaged_apps/packaged_apps.html#LARGE
http://www.oracle.com/technology/products/database/application_express/packaged_apps/packaged_apps.html#STICKY
Past that I recommend you just start playing with it. Once you have the framework figured out, which doesn't take long, you can build Ajax features very quickly.

Application Express Name Change???

All,
I know this is going to sound stupid... But, can someone give Application Express a better name?
Application Express is a better name than HTMLDB. And I can see why it's new name was chosen - it all makes sense.
The problem is with the seemingly duplicitous word "Express" in todays world. I know it means "Fast" in this case - that we can create applications quickly and easily. But for people that don't work with the software yet control which software is used or not (management), the word "Express" with regard to software has another meaning altogether.
Typically software is offered in various levels and the word "express" generally refers to the bottom of the heap. In Oracle it's no different: "Enterprise" is the big boy and "Express" is the starter. Just to prove the point, what if we called it Application Enterprise? (not that we should) But see how that just sounds better? It would inspire confidence from the start!
I just hate the fact that Application Express gets a bad rap from its name. It's the whole judging a book by its cover thing. Ok, I'll shut up now - I just had to make my thoughts known ;)
Regards,
Dan

Hi,
Joel's got the right idea. Just change your pronunciation from Ap-Ex, which invites management to ask "what's that stand for?" to A-pex. Of course, your boss must have a good enough English vocabulary to know what "apex" means! No promises there!
Photoshop Express was mentioned, which is the photo editor I use because I don't want to pay for and have the learning curve for the 800-pound gorilla that is Photoshop. I just want a fast way to get my photos (and web applications) done. On that basis, I like Application Express even better!

Knowledge n skills required to run Application Express

Hi Gurus,
Can anyone plz inform regarding the knowledge and skills that are required to create, run and maintain any application built using Application Express
i.e the skills required for an Administrator, Developer and any other that I forgot.
Thanks
Any help is appreciated.

It depends on what you plan on using it for, but for the basics:
<BR><BR>
Start by reading the 2 day developer that should make sense with a simple understanding of HTML, Javascript and SQL. Even without any knowledge or experience a bit of experimenting will have you using the tool relatively quickly.
<BR><BR>
The best thing is just to download XE and set it up as testing/learning APEX and see what you need to take it from there to where you want to go. Once you are experimenting and have more specific questions the forums should be more than enough to get going.

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.
