[ADF-11.1.2] Non Sense Associations and View Links while using Mysql as DB
Hello,
I recently started using Oracle ADF with MySQL at design time.
I am following instruction from http://www.oracle.com/technetwork/developer-tools/jdev/mysql-and-bc-howto-082060.html
With Jdeveloper, I created following tables with Mysql Database connection:
1. Company : (CompanyID, Name)
2. People : (PeopleID, FirstName, LastName, CompanyID [referencing CompanyID from Company Table])
Problem 1 : Everytime when I click OK button to create a "new Table" in mysql database, Jdeveloper throws error "Table Doesn't not exists". and when I refresh database connection, it shows me the new table. I don't understand why Jdeveloper is throwing error !
Once the table and linking between them is done, I can see 1-to-many relation between COmpany and People table on Database diagram ...
In Model Layer, I go for "Business Components from Tables" from 'New Gallery' where in I select both tables from mysql database to create EO & VOs of respective Table.
At the end, along of EOs and VOs, it also create following two associations and VL:
1. PeopleCompanyFkAssoc and PeopleCompanyFkLink >> 0..1 to * Cardinality Between People.PeopleID and People.CompanyID
2. PeopleCompanyFkAssoc1 and PeopleCompanyFkAsoc1Link >> 0..1 to * Cardinality Between Company.CompanyID and People.CompanyID
Problem 2 : 1st Association and VL doesn't make any sense at all !!! If Jdeveloper recongnize relationship correctly between tables on Database diagram and why can't it recongnize correct relationship while creating associations ? This problem is occuring for every table I create in Mysql database.
Also, http://www.oracle.com/technetwork/developer-tools/jdev/mysql-and-bc-howto-082060.html indicates following:
"+ADF BC does not automatically find the primary keys on your MySQL tables. That has two side effects. You'll see some errors when creating and modifying BC objects, and you'll have to define your BC primary keys manually. However, these errors should not affect your project.+"
But when my EO was created, it was already having Primary Key selected for correct attributes.
Anyways, please help in resolving Problem 2 ...
Timo,
Thanks for your reply but there is lot of headache, human errors in removing such VO and associations.
Jobinesh,
I am doing exactly what is described in here http://www.oracle.com/technetwork/developer-tools/jdev/mysql-and-bc-howto-082060.html
Expected Behaviour:
1. Create Following Association and VL, which is working fine.
PeopleCompanyFkAssoc1 and PeopleCompanyFkAsoc1Link >> 0..1 to * Cardinality Between Company.CompanyID and People.CompanyID
2. Do NOT Create any other non sense Association and VL, but it is creating
PeopleCompanyFkAssoc and PeopleCompanyFkLink >> 0..1 to * Cardinality Between People.PeopleID and People.CompanyID
What's the relationship between PeopleID and CompanyID ?

ADF Navigation List and View Links . any tutorial for this subject ?
Hi
Its two day that i am looking in oracle web site and tutorials that are provided in oracled ADF books.
but i can not figure it out how i can user a Navigation List , view Link to insert record in a child table.
so far i just could create a page that when i change the Navigation List selected item and then refresh that page , the related Fields of child table filled with master table PK.
although i cheched and i saw that ComboBox (Navigation List) auto submit is true.
does any one has a clue about this ?

Assoc and view links in Jdeveloper
Hi! I created two tables in DB with relationship 1 to 1. Then I created two EO in my app, but assoc and view links don't generated automaticaly. Where might be a problem?
Best regards, Debuger!I created two tables in DB with relationship 1 to 1What does this mean? Did you create foreign keys between the two tables?

[SOLVED] Multiple Dynamic View Objects and View Links - ADF Tree Table
Hi all,
I've got a method that creates 3 dynamic viewobjects using this:
ViewDefImpl Level1ViewDef = new ViewDefImpl("Level1View");
Level1ViewDef.addViewAttribute("LevelDescription","LEVEL1_DESCRIPTION",String.class);
Level1ViewDef.addViewAttribute("SetOfBooksId","SET_OF_BOOKS_ID",Number.class);

Level1ViewDef.setBindingStyle(SQLBuilder.BINDING_STYLE_ORACLE_NAME);
Level1ViewDef.resolveDefObject();
Level1ViewDef.registerDefObject();
ViewObject vo1 = createViewObject("Level1View",Level1ViewDef);I can create the view objects fine and create a single viewlink between two of them, however i'm getting problems with 2 view links.
This is how I'm creating a view link:
ViewLink Level2Level1FKLink = createViewLinkBetweenViewObjects("Level2Level1FKLink1",
"Level2View",
vo1,
new AttributeDef[]{
vo1.findAttributeDef("Level1")
vo2,
new AttributeDef[]{
vo2.findAttributeDef("Level1")
"LEVEL1 = :Bind_Level1");
ViewLink Level3Level2FKLink = createViewLinkBetweenViewObjects("Level3Level2FKLink1",
"Level3View",
vo2,
new AttributeDef[]{
vo2.findAttributeDef("Level2")
vo3,
new AttributeDef[]{
vo3.findAttributeDef("Level2")
"LEVEL2 = :Bind_Level2");I can get the data to display on an adf tree table if i'm only using a single view link, but when i try and implement 2 view link (for 3 levels on the adf tree table) i'm getting problems displaying the data.
I'm getting the following error:
Aug 10, 2007 2:44:39 PM oracle.adfinternal.view.faces.renderkit.core.xhtml.PanelPartialRootRenderer encodeAll

ADF BC: both ID and view link object as getter/setter in row impl
I notice something when generating the row implementation of VO that have links to other VO. I can't seem to find the logic behind it...
Following model:
users( id, address_id,name,firstname,...)
address(id, street,number,...)
their is an assosiation between the UsersEO and the addressEO. Their is also a view link between the UsersVO and the AddressVO based upon the assosiation of the EO's.
When we create the row implementation of the UsersVO we find a getter and setter for both the address_id as well as the address row object.
Why is this?
We have this issue because i added the UsersVO and the addressVO to the app module but i haven't added the link to the appModule but when i create the SDO from the appModule, the Users has both the address_id as the address row object.
THis does not seem to make sense. How do you use it correctly? Do you just need to set the address_id and can leave the row object null or do they both need to have the same? What if you set the address_id to 1 but the id in the address row object is set to 5...
How do the databindings handle these things?
To me it seems more logical that the VO only has a getter and setter for the address object and handles the address_id in the background according to the values in the address object.
Can someone explain me why this is implemented this way and how to handle it correctly?

Why is this? The definition of the VL allows you to optionally generate accessors for the underliying VOs, i.e. getAddressVO() in the UsersVO and getUsersVO() in the addressVO.
We have this issue because i added the UsersVO and the addressVO to the app module but i haven't added the link to the appModule but when i create the SDO from the appModule, the Users has both the address_id as the address row object. You should add the addressVO to the AM using the VL instead and not by itself.

As mentioned above, once you add the addressVO to AM using the VL, the framework will take care setting the value of the row objects accordingly. -
Need a how to on a special case for views and view links
I have a typical many-to-many relationship model I'm working on.
Basically, it looks like this:
User 1 -------------< * UserGroupXref *>--------------- 1 Groups
You see this in authentication modules all the time. A user can belong to multiple groups and group can contain multiple users.
My task is to use Business Components to create a form that manages user accounts. This form will consist of a User View (master) and 2 detail views.
The first detail view is a list of groups already assigned to the user. I've already defined a viewlink for this first group and it displays its many-to-many results ok.
The second detail view is a list of groups that are available to be assigned to the user. I was thinking that this detail view should be the product of a MINUS operation driven by a BIND VARIABLE. Being a query based view, I think its query would look something like this:
select group_id, group_short_name, group_long_name
from groups
minus
select xref.group_id group_id , group_short_name, group_long_name
from usergroupxref xref, groups
where xref.user_id = :bind_uid
and groups.group_id = xref.group_id
This introduces a bind variable which raises two questions:
1) Is there a better approach
2) How do you use a friggin bind variable?
Seriously, I noticed that the designer will not let you define a relationship based on a bind variable, which leads me to conclude that you have to pass the value at runtime from whatever client app you're using (SWING, JSF, etc). I really haven't found an example of using bind variables that suites me! Maybe someone can point me in the right direction ...?
Finally I have to add control buttons :
Add Group
Add All
Remove All
Remove Group
Naturally these buttons control the inserts and deletes from the xref table. Does this introduce another updateable view into the app or is it something that the framework somehow handles via the defined associations and what not?
I don't expect anyone to design the form for me, but maybe you can help me at least finish up these view links.
Thanks much!

Problem with af:table and view links
I want to display a table with data from a database table called PERSON, so I'm using af:table tag.
The PERSON table has the next fields:
PERSON_CODE
PERSON_NAME
PERSON_COD_STATE
The field PERSON_STATE is a foreign key to other table called PERSON_STATE:
PERSON_COD_STATE
DESCRIPTION
I've created a view to get data from PERSON table (personView). Because I want to show the person state description in the af:table , I've created another view to get data from PERSON_STATE table (personStateView). And I've also created a view link between personView and personStateView.
In the column of the af:table that represents the person state I drop the field 'description' of the state view linked to the person view.
When I run the JSP the state is not shown properly. All the persons are shown with the same state.
When testing directly with the application module, the view link works properly.
Does view links work inside a af:table?
I'm working with ADF 10g.
ThanksThanks for your reply.
The second alternative works, but I would be interested in the first one (using a view link).
The foreign key is defined properly:
PERSON.PERSON_CODE is a primary key.
PERSON.PERSON_COD_STATE is a foreign key.
PERSON_STATE.PERSON_COD_STATE is a primary key.
I have created a view link based on that foreign key.
When usign af:table to show the records of PERSON table, all the data of PersonView is properly shown. But the STATE of the person is not ok. It seems as the view link is not working.
Why?
Thanks -

How fast is findByKey and View Links
Hello,
I'm developing an application in which I'll have two very populated View Objects (one with ~1000 and other with ~13000). My code will pick up one row in the first view object and it will search the related rows in the second view object.
I have some questions about this operation:
1. Should I implement it by calling findByKey in the second View Object or View Links between them?
2. How fast is findBykey? O(n) or something better? And about the View Link, does it execute a SQL query or does it solve by comparison between Java objects?
Thanks,
EduardoThis reply from the community seems to say yes:
Ethernet = 1 Gbps
Wireless G, Wireless N (2.4 GHz) = 130 Mbps
Wireless N (5 GHz) = 300 Mbps
Wireless "g" is 54 Mbps, not 130 Mbps
This article from Gizmodo seems to say no:
http://gizmodo.com/5921456/apple-airport-express-2012-lightning-review-probably- the-best-router-ever
The article never even mentioned what type of download speed or plan was used, so the numbers are meaningless.
The AirPort Express has a 100 Mbps Ethernet WAN port, which would connect to a modem. Your download speed will depend on the Internet service plan that you have with your provider.
If you really do have a 100 Mbps download plan with your provider, you could probably expect about 85 Mbps because some speed is always lost in the routing process.
What is the speed of your plan with your ISP? -

6) After these entries the listener status after RESTART is as following:

The command completed successfully
7) Then in the tnsnames.ora file I added the following entry:
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(PROTOCOL = IPC)
(KEY = EXTPROC1521)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
test =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SID = test)
(HS = OK)
When i tnsping test, it works.
8) I edit the .bash_profile file for Oracle
ORACLE_HOME, ORACLE_BASE were already pointing to the correct destination, I added:
LD_LIBRARY_PATH=/usr/local/lib:/u01/app/oracle/product/11.1.0/db_1/lib:/u01/app/oracle/product/11.2.0/dbhome_1/hs/lib:/usr/lib64:/usr/lib
export LD_LIBRARY_PATH
ODBCINI=/etc/odbc.ini
export ODBCINI
ODBCINSTINI=/etc/odbc.ini
export ODBCINSTINI
ODBCSYSINI=/etc
export ODBCSYSINI
9) Then i configured $ORACLE_HOME/hs/admin/inithsodbc.ora
And Modified these lines:
HS_FDS_CONNECT_INFO = test
HS_FDS_TRACE_LEVEL = ON
HS_FDS_TRACE_FILE_NAME = odbc_test.log
HS_FDS_TRACE_LEVEL = 4
HS_FDS_SHAREABLE_NAME = /usr/lib64/libodbc.so
HS_FDS_SUPPORT_STATISCTICS = FALSE
HS_LANGUAGE = AMERICAN_AMERICA.WE8ISO8859P1
set ODBCINI = /etc/odbc.ini
10) Then i created a database link with the following command:
Create public database link test connect to test identified by test using ‘test’;
I tried username and password in database link with double quotes also.
11) Now Finally when I try to select records from mysql table:
select count(*) from "table"@"test"; -- I have tried with and without double quotes
I get the following error:
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
ORA-02063: preceding line from TEST
How to get through this error, and how to check logs for HS?
Your help is required.

Edited by: misterimran on Dec 27, 2011 1:21 PMHi,
In your listener.ora for the DG4ODBC entry you had -
(ENVS=LD_LIBRARY_PATH = /usr/local/lib:/u01/app/oracle/product/11.2.0/dbhome_1/lib)
but this should also include the path for the driver manager directory which in your case is /usr/lib64 so could you add this ?
The error -
Failed to load ODBC library symbol: /usr/lib64/libmyodbc3.so(SQLSetDescRec)
indicates the /usr/lib64 directory cannot be accessed.
The entry should then look like -
(SID_DESC =
<space>(PROGRAM = dg4odbc)
<space>(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
<space>(SID_NAME = test)
<space>(ENVS=LD_LIBRARY_PATH = /usr/local/lib:/usr/lib64:/u01/app/oracle/product/11.2.0/dbhome_1/lib)
<space>)
The spaces may have bene lost when posting but there should be at least one space in the file as indicated by the <space>.
After making the change then stop and start the listener.
If you still have problems then please post again the current versions of the configuration files, the full errors shown in SQLPLUS for a select and the output from a debug trace showing the errors.
The information shows you are using the 3.51 MySQL ODBC driver so could you also try with the latest version of the 5.1 driver and see if you have the same problem ?

I occasionally have the need to export photos from the iPad to an SD card (photos that were imported using the camera kit). This is useful for e.g. to print photos while travelling. So far I have not found this functionality anywhere, including in any apps available on iTunes. Can anyone help?
The camera connection kit can only be used to import photo/video files from a camera, SD card or USB flash drive. You can't import other types of files. You can't export any type of files using the camera connection kit.
