Integrity Constraints about JDeveloper and TopLink External MW

Hi there,
we are using external toplink mapping workbench in order to do the toplink descriptor mappings. And within JDeveloper, we want to create EJB Session Facade beans that use the pojos we've created by external toplink mw. But, because JDeveloper cannot understand that the classes, which are created by external toplink mw, are toplink pojos, we cannot indicate the pojos in the "create session facade" wizard of the JDeveloper. So we cannot create the session facade beans automatically.
By the way, Jdeveloper cannot open External Mapping Workbench project file (*.mwp) internally. And viceversa, External Mapping Workbench cannot open Jdeveloper's internally created project file. Because, I think, JDeveloper saves the toplink project with 9.0.4 version. But our external Mapping Workbench saves the toplink project with 10.1.3 version. But, the interesting thing is, when we look at the toplink jar that JDeveloper uses, we see that its version is 10.1.3.
How can we make JDeveloper understand that the external classes are real TopLink POJOs so that we can create EJB Session Facade Beans by the wizards?
Thanks for help.

JDeveloper and Toplink

I am having problem using jdev and toplink. The toplink xml file ([projectname].xml) in the src/meta-inf directory is no longer being updated from the changes made in the class descriptors and toplink mapping file (mwp).
How do i fix this ? If not all the changes I made in Jdev are not translated into the toplink xml and when deployment I am encountering errors.

You should probably ask this on the TopLink forum - but basically you need to either be working on TopLink from inside JDeveloper or from the mapping workbench - you can't work on a project from both at the same time.

HT4878 Why is this data chart Timeline multi colored (in About/Storage) and the external drive is only pink?

1. When viewing the Storage Timeline for my Macbook and the External Drive for the Time Machine backup instead of multi-colored bars the data is only showing a one pink one. Is that because it is all "backup" on the external? 2. Is the discrepancy in size the OS being left out? Thanks.

Time Machine makes full backups of the hard drive. If you want to change this, you can open System Preferences > Time Machine > Options, and add excluded items. However, I recommend you to keep backing up the whole drive, so you will be able to restore the whole backup in case of a hard disk failure

How to export-import referential integrity constraints ?

Hi all
Is there any way to export only the referential integrity constraints from one user to another user ?
Suppose i am having SCOTT user which is having EMP , DEPT tables . And also I am having another user (say TEST) which also is having those EMP and DEPT table but without the referential integrity constraints . Now can i export
referential integrity constraints from SCOTT and import into TEST so that EMP,DEPT tables(in TEST) will have those referential integrity constraints which are present in SCOTT user ?
Thanks

SiteMinder integration with the internal and external facing portals

Hi ,
We are in development phase for SiteMinder integration with the internal and external facing portals.The proposed dual authentication scheme which requires both SiteMinder for External facing portal (EFP) and LDAP for Internal portal .is it possible?
and is it possible to main to diff LDAP directories one is external users and one is for internal users.?
If you maintain 2 diff(external & internal) LDAP Directories in Siteminder Policy Server what about external users which are not exit in portal data source .
I appreciate if anyone can help me for my above query .
Regards
Tag

Hey Tag,
We do have a physical external Portal and a physical internal portal. The both the external and internal are connected to 2 LDAP directories.
For example the External Portal is connected to the Employee LDAP Direcotry and the Customer LDAP Directory. The Internal Portal is connected to the US Employee LDAP Direcotry and the EMEA LDAP Directory.
So each one of them is connected to 2 different LDAP Directories.
I believe that the Siteminder Policy is setup such that the Internal portal has a policy and the External portal has a seperate policy on the same Siteminder Server. Then each of the Policies is configured to connect to the approiate LDAP Directories.
You have to maintain the LDAP Directory information in both the portal and Siteminder Policy Server. It is required in the policy server so that it can authenticate the user and it is required in the Portal server so that it can authorize the user and display content based on thier assigned roles.
Hope that helps.

Keith

Toplink Delete Integrity Constraint.

I have been beating my head against my key board for a few days on this.
Note: Names of packages/class names/DB info altered because I am paranoid.
Excerpts from my toplink log....
Deleted Objects:
Key: [588504]     Identity Hash Code: 25872956     Object: ChildClass@18aca3c#588504
Key: [629458]     Identity Hash Code: 1812473     Object: ChildClass@1ba7f9#629458

DeleteObjectQuery(ChildClass@1ba7f9#629458)
DeleteObjectQuery(ChildClass@1b52301#588850)
Somehow generates these delete statements..
DELETE FROM T_PARENT_CLASS WHERE (ID = 321712)
DELETE FROM T_CHILD_CLASS WHERE (ID = 588504)
DELETE FROM T_CHILD_CLASS WHERE (ID = 629458)
DELETE FROM T_CHILD_CLASS WHERE (ID = 588850)
End Batch Statements
Obviously this error is generated.
Exception [TOPLINK-4002] (Oracle TopLink - 10g Release 3 (10.1.3.1.0) (Build 061214)): oracle.toplink.exceptions.DatabaseException
Internal Exception: java.sql.BatchUpdateException: error occurred during batching: ORA-02292: integrity constraint (FK_CHILD_PARENT) violated - child record found
Error Code: 17081
     at oracle.toplink.exceptions.DatabaseException.sqlException(DatabaseException.java:282)
...ect
I think this has something to do with Toplink trying to order my deletes in a way they think they should be and ignoring the way I asked Toplink to delete the objects...
Any help with this would be greatly appreciated.

The ChildClass class is not privately owned. Obviously the FK Constraints are set up.
The problem may be because that the ParentClass can share the same ChildClass. ChildClassesA does not contain the same objects in ChildClassesB.
unitOfWork.deleteAllObjects(parentClasses);
unitOfWork.deleteAllObjects(childClassesA);
unitOfWork.deleteAllObjects(childClassesB);
I have tried the line below from the 10.1.3 user guide with no success. getDescriptor() is deprecated so I am not sure why it is in the user guide. Is there a better way to do this? I would think that you would not have to do this at all if you have FK constraints set up and you specify that you want to delete all the parents BEFORE you even start deleting the child classes.
session.getDescriptor(ParentClass.class).addConstraintDependencies(ChildClass.class);

I have question about hooking up an external hdd to a time capsule and still have my printer hooked up as well. Anyone got any tips for me, how to do it and what brand of harddrive that will work best for me 1 or 2 TB

i have question about hooking up an external hdd to a time capsule and still have my printer hooked up as well. Anyone got any tips for me, how to do it and what brand of harddrive that will work best for me 1 or 2 TB

You just need a powered hub.. if you already use one then fine.
Plug in just about any external hard disk will work fine. Format has to be readable by the TC.. ie fat32.. or much better HFS+.. plug it into a Mac to prepare the drive.
Pick whatever size suits.. nowadays 2TB are most economical.
WD, Seagate have goobled up all the minor players.. so pick one.
Whatever suits your budget and asthetics.
NOTE.. The USB on the TC is fine for printers.. IMHO it is the wrong way to go with USB disks.. use the internal disk of the TC.. USB is less than half the native speed plugged into a Mac.. TC to USB is slow.. far slower than internal drive.. or using external drive as external.

SQL*Loader and integrity constraints

I am running into trouble with integrity constraints in my SQL*Loader script runs. Should I be going up to unix and removing the constraints from sqlplus, then asking the wizard to reinstall them after the data load? Is this documented somewhere? I can't find it. Sorry for asking such a basic question.
Thanks,
Ann Cantelow

Hi,
Your approach is correct.
Create tables first
Move data via the scripts
Create contraints, indexes, primary keys

JDeveloper Prerelease 10.1.3 and toplink

Hello,
I know ADF is not supported but could someone tell me please if the new prerelease of JDeveloper supports toplink and if so how well is it supported? I mean by that does it have many quirks because it is a prelease.
If anyone out there using it feedback would be great.
Thanks much,
Alex.

The 10.1.3 J2EE Download contains TopLink, but you won't get the easy binding to the user interface that you get with ADF.
Since it is a developer preview you might encounter problems and glitches, if you do please report them on this or the TopLink forums so we can fix them for production.
If you want a production version of JDeveloper with full TopLink support check out the new 10.1.2 release - a lot of toplink improvments in there.

Hello. I keep my IPhoto library (about 90GB) on an external HD and am trying to back it up to another external drive. Both are formatted Mac OS Extended (Case-sensitive, Journaled). Recently, backup has failed from the start due to error 36. Howtoresolve?

Hello. I keep my iPhoto library (about 90GB) on an external HD and am trying to back it up to another external drive. Both are formatted Mac OS Extended (Case-sensitive, Journaled) and both check out when scanned with Disk Utility. Recently, backup has failed from the start due to error 36. Any ideas how to resolve? Also, what's the maximum recommended size for an iPhoto library file? Thx!

Since you can't drag the library to the other EHD for the backup see if you can duplicate it (if you have enough room on the drive) by selecting it and typing Command+d (duplicate).
If you do rebuild the library without a backup and it goes awry you won't lose your photos but you may lose your orgnaizational efforts. So try the following:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library in the location of your choosing based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
NOTE: Fix 2 above might be the method you might want to try first with iPLM creating the new library on your second EHD. If it works that would get your backup copy on the second EHD at the same time as repairing it. If it does'nt work then go back to Fix 1.

Differences between trigger and Integrity Constraints

waht are the differences between trigger and Integrity Constraints

waht are the differences between trigger and Integrity ConstraintsConstraints are to be preferred:
"Declarative Ease
Define integrity constraints using SQL statements. When you define or alter a table, no additional programming is required. The SQL statements are easy to write and eliminate programming errors. Oracle controls their functionality. For these reasons, declarative integrity constraints are preferable to application code and database triggers. The declarative approach is also better than using stored procedures, because the stored procedure solution to data integrity controls data access, but integrity constraints do not eliminate the flexibility of ad hoc data access.
Centralized Rules
Integrity constraints are defined for tables (not an application) and are stored in the data dictionary. Any data entered by any application must adhere to the same integrity constraints associated with the table. By moving business rules from application code to centralized integrity constraints, the tables of a database are guaranteed to contain valid data, no matter which database application manipulates the information. Stored procedures cannot provide the same advantage of centralized rules stored with a table. Database triggers can provide this benefit, but the complexity of implementation is far greater than the declarative approach used for integrity constraints."

Information about Integration WebDynpro for ABAP and Business-Workflow

Hi Experts,
I'm looking for information about
Integration WebDynpro for ABAP and Business-Workflow
Link, documents and books are welcome!
Thanks
mishak

If you have worked on workflows earlier the procedure is very simple. You just need to enter certain parameter values of your application in SWFVISU for the respective task and re-register your system in UWL administration. Thats it! your webdynpro and workflows are integrated. For details on the parameters check the following link,
http://help.sap.com/saphelp_nw04/helpdata/en/19/bff5c18ba44da4a4ca68cf572dabda/frameset.htm
There are also a couple of blogs on "launching webdynpro from UWL" (Procedure for both Java and webdynpro is almost similar). You can also check these for more details.

About licensing the Jdeveloper and ADF

Hello everybody :
I have a little doubt about the "JDeveloper and ADF" license
I am planning to start my project using it and I have read the license [http://www.oracle.com/technetwork/licenses/jdev-license-152012.html] and I understood that everything is free for single user except Web Logic server needs to be licensed .
Is that what I have understood correct or not ?
Can I use this tool for developing my small project for my small business enterprise but the only one thing that I am afraid of is in the future I might face some limitations with the Web Logic Server or with any tool of Jdeveloper and ADF , So Shall I start up my project or should I search for another different tool such as Netbeans .
I would like to hear the answer before I put my self in trouble .
Thanks a lot

Well, this will cost you more money the buying a licence as you break the law. To find out what you have to pay you better call a sales person in your area (see home oracle page).

Integrating FTP with JDeveloper

Can anyone help me with integrating FTP with JDeveloper (10.1.3)
I am developing jsp pages for a web site. the website runs on a Sun Solaris UNIX server.
At present i develop my jsp pages in JDeveloper and save then to a file on my PC. I then have to use an external tool (Ultraedit) to FTP them to my webserver for testing.
I have seen in this forum that there is something called 'ant' which will allow you to FTP direct from JDeveloper. I know zero about 'ant' and after spending a couple of hours trawling arround the web i'm still no wiser.
Can someone give me a hands held, idiot friendly explanation of what i have to do to integrate FTP?
john

Here is a basic explanation of the FTP task in ANT.
You can just create a new Ant build file in your project, add this task with the correct parameters and then right-click run on the build file.
Another options is to use JDeveloper to create standard WAR file for deployment and then passing it to the server to deploy.

A While ago, in this thread JDeveloper 10g, XSQL and FOP , was mentioned an ongoing effort for the "integration of Oracle's XML Publisher in JDeveloper and XSQL Servlet", Is this still happening ?, will this be something will be able to use without having to be an Oracle Apps shop? Any additional info would be appreciated.

Hi,
is there any progress about XML publisher integration with JDeveloper. I'm right now examining XML publisher but there is no explicit directions and explanations of using XML publisher with jdeveloper.
any news !?
