Question about the Create Session Bean Wizard

Hi,
I'm using the Session Bean Wizard to generate a session facade in EJB 3.0. In step 2 «choose methods to expose through this facade», I only see 2 methods generated for each entity: findAll and remove.
When I click Help on this page, the documentation specify the following:
«Use the tree control to specify the core methods and entity methods you want to generate. Core Facade Methods Theese methods are used for basic CRUD (create, read, update, delete) functionality. »
So why is the wizard only offering to generate findAll and remove?
Also the remove method generated does not seem to delete anything as in the following :
public void removeDcaRole(DcaRole dcaRole) {
final EntityManager em = getEntityManager();
try {
final EntityTransaction et = em.getTransaction();
try {
et.begin();
dcaRole = em.find(DcaRole.class, new DcaRolePK(dcaRole.getDcaNo(), dcaRole.getTRoleCode()));
et.commit(); // where is the delete ???
} finally {
if (et != null && et.isActive()) {
et.rollback();
} finally {
if (em != null && em.isOpen()) {
em.close();
Can I use the remove method as a starting point to an update ?
Any comment on this would be appreciated.

There are update and insert methods under the "core" section/

A question about the create object command

Hi, I met some problems when created type and view:
In sqlplus,
1) I first create a address_ty:
create or replace type address_ty as object
(street varchar2(50),
city varchar2(25),
state char(2),
zip number);
type created
2) Then I created a person_ty;
create type person_ty as object
(name varchar2(25),
address address_ty);
type created
3) create the table customer;
create or replace table customer
(customer_id number,
person person_ty);
table created
4) create the view based on the customer table;
create view customer_0v(customer_id, person) as
select customer_id,
person_ty(name,
address_ty(street,city,state,zip))
from customer;
***There is a error message :
error at line 4: address_ty(street,city,state,zip))
invalid column name.
I think it should work but ...
5) Another question is could I insert into table customer values like this:
insert into customer values
(123,'SIGMUND','47 HAFFNER RD','LEWISTON','NJ',22222);
It does not work in my pc and give a erro message like ' too many valuesj'.
But some of books said it works.
Thanks for any help !
echo
null

Why does not the Object itself implement the interface
CloneableBecause then every object would be cloneable.

Question about the "Create Web Gallery" function in Bridge

I created a beautiful Web Gallery using Bridge's built-in function which creates a Photoshop Web Gallery.
Everything works great except for one thing. When I click the "E-Mail Feedback" button, Apple Mail loads and creates blank e-mail message. This is all good, but for some reason the address line is loading up with data instead of just an e-mail address. I was hoping someone versed in html could tell me what I'm doing. The source code in ThumbnailFrame.html looks like this:
function sendFeedback(picName) {
checkForUnSavedChanges(picName);
var prefix = "mailto:[email protected]";
var name = null;
name = prompt("Enter Your Name:", "Your Name");
if (name) {
prefix += "subject=" + escape("Feedback from " + name);
prefix += "&body=";
var str = ""
for (var i in feedback) {
str += i + " ~~ \n";
str += (feedback[i].approved == true) ? "Approved ~~ \n" : "";
str += (feedback[i].other == true) ? "Other ~~ \n" : "";
str += (feedback[i].comments != "") ? ("\nComments:\n" + feedback[i].comments + " ~~ \n") : "";
str += "____________________________________________\n\n";
The address line in the Apple Mail message looks like this: [email protected]=Feedback from Paul Kirtley&body=
I want it to look like this: [email protected]
By looking at the source code above, can someone tell me how I can make an adjustment to keep "subject=Feedback from Paul Kirtley&body=" out of the address line?
Thanks!

Error when Create Session Bean in JDeveloper

Hi All,
I followed the steps in the SRDemo tutorial to create Session bean SRPublicFacade. I used Create Session Bean wizard. Step 1 was ok. Step 2 when it's supposed to show all the POJOs and all methods (from Queries) it hang there, and skipped to Step 3 and so on... As a result I had an empty Session Bean with only class name and no methods in it. I do have correct database connection, and I have another project with similar Session Bean sucessfully. I just don't know what happened to this project or the way I created session bean this time. Any conflict when create Session Bean to the same database or something(?) Anyone has any idea please let me know.
Thank you very much,
John

Frank,
Yes, I compiled the project before building the session facade. I used JDeveloper 10.1.3.3.0
The thing is I once created successfully the session facade in another project, like SRdemo. Now I would like to repeat that in another project say SRdemo2, then it went wrong. It skipped step 2 in the wizard and look like it cannot detect the tables and named queries.
Thanks,
John

Question about the order to creating Account, Contact, Contact Role

Hi, my friends,
I have some questions about the order of creating Account, Contact, Contact Role, etc in Web Service 1.0. I could create them in the following case:
1. Insert Contact object and get contactId (now new contact exists in CRMOD)
2. Insert Account object with Contact Role child associated with contactId
My questions are:
1. Do we have the following order? Insert new Account with new Contact child and Contact Role child (Contact is new and does not exist in CRMOD).
2. Looks like system need accountId, contactId, etc to make the objects relationship. Is there other field having the same function?
Thanks
Ray

Hi Ray,
In response to your questions:
1. Do we have the following order? Insert new Account with new Contact child and Contact Role child (Contact is new and does not exist in CRMOD).No. Both the Account and Contact must already exist. The Role value is an attribute on the Account Contact relationship, this relationship must exist in order to assign a role value to it. This is consistent with the behaviour of the UI, when you press the New button on the Contact child applet, you are taken to the Contact New page where you can create a Contact record. Once you save, the relationship is created but you cannot assign a role value unless you click the Edit Roles link next to the new Contact.
2. Looks like system need accountId, contactId, etc to make the objects relationship. Is there other field having the same function?Correct, the system needs to know which Account/Contact pair is being assigned a role value. To do this the Account and Contact values must be uniquely identified using the Id values for each.
I hope this helps.
Thanks,
Sean

A question about the IE management of session id

Hi, guys! I have a question about the IE browser management of session id.
As we know, firefox browser will use cookie to record session id, so if we delete the cookie files then the client can't find target session.
But it's not the same as IE browser.I found I already can find target session after I delete the cookies.
Then I think maybe IE browser use URL rewrite mechanism(GET request) and hidden text mechanism(POST request), but I'm not sure!
Or maybe IE browser use current IE window process's cache to record the session id?
Please help me, thank you very much in advance!
I'm Chinese, my English is so bad, please understand, thanks.

Thank you for your answer, but I still have a question.
Can you tell me how your deleting cookies works? I just use IE browser tools->Internet Options->Delete Cookies to delete my cookie, but the session still can be retrieved! Just like you said, the session id is kept in the memory.
But if I use firefox to do the same operations, the session will can't be retrieved.Does that mean firefox not only delete cookies' files but also delete them in the memory.
Can I use IE browser to do the same effect as firefox browser? And how to do? Thank you.

A question about the impact of SQL*PLUS SERVEROUTPUT option on v$sql

Hello everybody,
SQL> SELECT * FROM v$version;
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
PL/SQL Release 11.2.0.1.0 - Production
CORE    11.2.0.1.0 Production
TNS for Linux: Version 11.2.0.1.0 - Production
NLSRTL Version 11.2.0.1.0 - Production
SQL>
OS : Fedora Core 17 (X86_64) Kernel 3.6.6-1.fc17.x86_64I would like to ask a question about the SQL*Plus SET SERVEROUTPUT ON/OFF option and its impact on queries on views such as v$sql and v$session. Here is the problem
Actually I define three variables in SQL*Plus in order to store sid, serial# and prev_sql_id columns from v$session in order to be able to use them later, several times in different other queries, while I'm still working in the current session.
So, here is how I proceed
SET SERVEROUTPUT ON; -- I often activate this option as the first line of almost all of my SQL-PL/SQL script files
SET SQLBLANKLINES ON;
VARIABLE mysid NUMBER
VARIABLE myserial# NUMBER;
VARIABLE saved_sql_id VARCHAR2(13);
-- So first I store sid and serial# for the current session
BEGIN
    SELECT sid, serial# INTO :mysid, :myserial#
    FROM v$session
    WHERE audsid = SYS_CONTEXT('UserEnv', 'SessionId');
END;
PL/SQL procedure successfully completed.
-- Just check to see the result
SQL> SELECT :mysid, :myserial# FROM DUAL;
    :MYSID :MYSERIAL#
       129   1067
SQL> Now, let's say that I want to run the following query as the last SQL statement run within my current session
SELECT * FROM employees WHERE salary >= 2800 AND ROWNUM <= 10;According to Oracle® Database Reference 11g Release 2 (11.2) description for v$session
http://docs.oracle.com/cd/E11882_01/server.112/e25513/dynviews_3016.htm#REFRN30223]
the column prev_sql_id includes the sql_id of the last sql statement executed for the given sid and serial# which in the case of my example, it will be the above mentioned SELECT query on the employees table. As a result, right after the SELECT statement on the employees table I run the following
BEGIN
    SELECT prev_sql_id INTO :saved_sql_id
    FROM v$session
    WHERE sid = :mysid AND serial# = :myserial#;
END;
PL/SQL procedure successfully completed.
SQL> SELECT :saved_sql_id FROM DUAL;
:SAVED_SQL_ID
9babjv8yq8ru3
SQL> Having the value of sql_id, I'm supposed to find all information about cursor(s) for my SELECT statement and also its sql_text value in v$sql. Yet here is what I get when I query v$sql upon the stored sql_id
SELECT child_number, sql_id, sql_text
FROM v$sql
WHERE sql_id = :saved_sql_id;
CHILD_NUMBER   SQL_ID          SQL_TEXT
0              9babjv8yq8ru3    BEGIN DBMS_OUTPUT.GET_LINES(:LINES, :NUMLINES); END;Therefore instead of
SELECT * FROM employees WHERE salary >= 2800 AND ROWNUM <= 10;for the value of sql_text I get the following value
BEGIN DBMS_OUTPUT.GET_LINES(:LINES, :NUMLINES);Which is not of course what I was expecting to find in v$sql for the given sql_id.
After a bit googling I found the following thread on the OTN forum where it had been suggested (well I think maybe not exactly for the same problem) to turn off SERVEROUTPUT.
Problem with dbms_xplan.display_cursor
This was precisely what I did
SET SERVEROUTPUT OFFafter that I repeated the whole procedure and this time everything worked pretty well as expected. I checked SQL*Plus documentation for SERVEROUTPUT
and also v$session page, yet I didn't find anything indicating that SERVEROUTPUT should be switched off whenever views such as v$sql, v$session
are queired. I don't really understand the link in terms of impact that one can have on the other or better to say rather, why there is an impact
Could anyone kindly make some clarification?
thanks in advance,
Regards,
Dariyoosh

Hi Dariyoosh,
SET SERVEROUTPUT ON has the effect of executing dbms_output.get_lines after each and every statement. Not only related to system view.
Here below what Tom Kyte is explaining in this page:
Now, sqlplus sees this functionality and says "hey, would not it be nice for me to dump this buffer to screen for the user?". So, they added the SQLPlus command "set serveroutput on" which does two things
1) it tells SQLPLUS you would like it <b>to execute dbms_output.get_lines after each and every statement</b>. You would like it to do this network rounding after each call. You would like this extra overhead to take place (think of an install script with hundreds/thousands of statements to be executed -- perhaps, just perhaps you don't want this extra call after every call)
2) SQLPLUS automatically calls the dbms_output API "enable" to turn on the buffering that happens in the package.Regards.

Some questions about the integration between BIEE and EBS

Hi, dear,
I'm a new bie of BIEE. In these days, have a look about BIEE architecture and the BIEE components. In the next project, there are some work about BIEE development based on EBS application. I have some questions about the integration :
1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?
2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?
3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?
4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?
could anyone give some guide for me? I'm very appreciated if you can also give any other information.
Thanks in advance.

1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?You, shud consider OBI Application here which uses OBIEE as a reporting tool with different pre-built modules. Both 10g & 11g comes with different versions of BI apps which supports sources like Siebel CRM, EBS, Peoplesoft, JD Edwards etc..
2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?Its independent of any soure. This is OBIEE modeling to create RPD with all the layers. If you build it from scratch then you will require to create all the layers else if BI Apps is used then you will get pre-built RPD along with other pre-built components.
3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?BI apps comes with pre-built ETL mapping to use with the tools majorly with Informatica. Only BI Apps 7.9.5.2 comes with ODI but oracle has plans to have only ODI for any further releases.
4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?User will still see old data because its good to turn on Cache and purge it after every load.

Some question about the renegotiation function in SRM Contract (GOA)

Hi All Expert,
We are on SRM 5/4.6, there is a question about the renegotiation function in SRM GOA.
Can we renegotiate the price for some parts in the GOA items with this function ( e.g. Only renegotiate one item in the contract) ?
Will the item price updated automatically after the renegotiation?
Many thanks in advance!!!
Wendrin

Hi Sanjeev,
Many thanks for your help.
One more question, if I add a new item when we renegotiation, will it be transfered to contract and create a new item after that?
Thanks and best regards
Wendrin

Questions about the content of download meeting recording .zip file

I tried posting this on the resurrected Connect forum, but my Adobe ID wasn't recognized there....
Concerning the files that are included in the .zip file of the meeting recording that can be downloaded:
1) Is there any documentation describing the files and their contents (i.e. what each file represents, what each XML element and attribute in those files represent)
2) Are there any files that capture mouse movement on a shared desktop?
Thank you!

Hi Sean,
Regarding your first post:
Thanks Jorma! I don't have access to an FMS build at the moment but I'm quite certain it's there. As for contacting Jaydeep, I am 90% sure he authorized us to broadcast his email on here if folks had questions about the tool, but, in the case that I'm wrong and he didn't - I'm going to double-check first.
Regarding your most recent post..
"To be clear, the most critical goal I'm trying to accomplish is to create an automated process that will download the recording meeting at its highest quality in a consistent and reliable manner".
I personally believe this is possible; unfortunately, I haven't seen it done yet. If your recording contains:
- audio
- a camera feed
- screensharing
Then I think you might be able to get this going. If it contains shared content, like a shared PPT, this gets trickier.
"To do this, of course, I have to reproduce some of the functionality that Connect provides, starting and combining video and audio streams according to the instructions in the control files."
Exactly right. If your recording didn't contain shared content, then all you've got on your hands are a bunch of audio/video files that you could edit together as you wanted with your favourite video editing tool. If it contains shared content, here's (at a high level) what's happening.
For shared PPTs or FTContent files:
First (for version 9 recordings only), Connect reads the information on the Shared Content's location and SCO within mainstream and indexstream and validates it before loading it. I don't recall this happening to the same extent with version 8 or earlier, but maybe it was. Now, if the content is validated (ie. Connect can find it) the share pod will display as black, if it doesn't, you get an empty pod with an message like "No content is being shared" or something like that.
Connect then looks at the actual FTContent file, and loads the content that is to be shared using the file path and sco ID listed in here. It's important to note that the SCO ID and file path in here will likely not be the same as the original file you uploaded to your room, it's a new SCO id (I believe SCOs of this type are called referenced scos) and new path.
Now...if I was going to build some sort of player which would play all these files in one screen to make a recording...I might not want to use Connect's code here. If you know the file path to the shared content (from FTContent), you could easily view it with the content URL (conveniently also in FtContent). I'm not a coder, but I'm envisioning something like Presenter's GUI where you've got the presentation's content in the main area, and a video file (if there is one) playing back on the side.
Anyways, food for thought if you want to try to go about this. Connect recordings are incredibly complex and they come with a big learning curve, but if you can make sense of them the knowledge is quite valuable.

N00b question about the ABS

Hey, I am new to Arch and I'm about to install it on my machine (used it a bit in a virtual machine) and I have a small nooby question about the ABS.
According to the wiki: https://wiki.archlinux.org/index.php/Arch_Build_System
"Running abs as root creates the ABS tree by synchronizing with the Arch Linux server."
Does this mean that the ABS tree (not the package) is always downloaded from the official Arch Linux servers, never from any of the mirrors?

jomasti wrote:
ANOKNUSA wrote:makepkg is part of the abs package.
You might be confusing that with makeworld. makepkg is included with pacman.
Anyway, gregor, you are confusing the AUR with ABS. Although, what you are saying is still possible via the source files when looking up a package on https://www.archlinux.org/packages/. But with both, using a program or using the respective page is a personal choice.
Yup, you're right. My mistake.

SUP - 2 questions about the CDB (cache database)

Hi,
I have 2 questions about the cache database and the cache groups:
1 - How does the "On demand" cache group policy exactly works? I know that online cache group is without storing any data on the CDB making direct requests to de backend from the device, the DCN is based on updating from the backend, the scheduled is based on a time period, but I don't understand how the "on demand" exactly works, and why it has a time period too.
2 - Is it possible to query the cache database table to check the data that SUP has stored? How can I do this?
Thank you!

I posted a similar question in SUP Apps project not too long ago and Paul Horan provided this useful reply:
Create a "Sybase ASA v12.x for Unwired Server" connection profile in the Enterprise Explorer. I named mine CDB.
: Host = localhost (or whatever the machine name is)
: Port = 5200
: Database name = "default"
: User Name = "dba"
: Password = "sql"
Obviously, change the userid/password to match, if you changed them during install time.
Connect, and you'll see the "default" database displayed.
Navigate down through the Tables folder, and the first subfolder is labeled something like [#should_delete_sk ...] Start there.
You'll see a bunch of tables with the naming convention "D1" + package name + package version + MBO name. These are the cache tables for the MBOs.

Question about the function module (RFC_READ_TABLE)

Dear everyone
Could I ask you a question about the function module (RFC_READ_TABLE)?
I was asked if it's possible to create a report which compares the data between different SAP systems (both production systems).
Now, the easiest way would be to use the function module (RFC_READ_TABLE) within a SAP infoset query (SQ01 type query).
But I heard the rumor that using the function module (RFC_READ_TABLE) is not advisable due to the security reason.
However, I am not exactly sure what sort of security problems this function module can possibly have...
Would you help me on this?
I also would like to know if using "remote enabled module" type function module can always overcome this possible security issue.
Or, are there any points that I need to be careful about even when I use "remote enabled module" function module?
Thank you very much in advance.
Takashi

Dear Fred-san
Thank you very much for your support on this.
But, may I double check about what you mentioned above?
So, what you were mentioning was that if some user executes the query with
the function module (RFC_READ_TABLE), under the following conditions, he can access to
the HR data even when he does not have the authorizations for HR transactions?
<Conditions>
1. the user has the authorization for HR database tables themselves
2. RFC_READ_TABLE is called to retrieve the data from HR database
<example>
Data: LF_HR_TABLE like DD02L-TABNAME value 'PA0000'.
CALL FUNCTION 'RFC_READ_TABLE'
   EXPORTING
    query_table                = LF_HR_TABLE
TABLES
   OPTIONS                    =
   fields                     =
   data                       =    .
But then, as long as we call this function module for a non-critical tables such as
VBAP (sales order) or EKKO (purchase order) within our query, it wouldn't seem to be
so security risk to use RFC_READ_TABLE...
Besides, each query (infoset query) has got the concept of user groups, which limits
the access to the queries within the user group.
※If someone does not belong to the user group, he cannot execute the queries within that
   user group, etc
So, my feeling is that even infoset queries does have authorization concept...
Would you give me your thought on this?
I also thank you for your information for SCU0.
That is an interesting transaction
Kind regards,
Takashi
