Avoid NOT NULL error on CMR

When I try to create an EJB with an CMR field passed on the ejbCreate I have two options:
1. set the CRM in ejbCreate (setXXX method): not posible, illegal state (ok by EJB 2.0 specifications)
2. set the CMR in ejbPostCreate (setXXX method): not posible - after ejbCreate the container tries to make the insert and gets the "unable to insert null into XXX" because the id of the CMR must be set NOT NULL in the database.
On bea there is something like delay-insert-until ejbCreate or ejbPostCreate.
What are my options on oc4j 9.0.3?

I will state the obvious, but nevertheless, have you restarted the j2ee engine?

Avoid JDBC sender error: Execute statement did not return a result set

Hi!
My JDBC sender adapter towards MS SQL server works fine, with an Execute statement calling a stored procedure that returns the source data needed. The stored procedure itself updates the status of database table records, so that only the unread records are returned each time the stored procedure is called.
However, the communication channel monitoring sets a red flag for the JDBC sender adapter, when there are no values to fetch from the database table (using the stored procedure). Message says: "Database-level error reported by JDBC driver while executing statement 'EXECUTE FetchMessage 1, 9000'. The JDBC driver returned the following error message: 'com.microsoft.sqlserver.jdbc.SQLServerException: The statement did not return a result set.'. For details, contact your database server vendor."
This is not an error situation, as I do not expect there to be any values to fetch from the database at all times.
I do not see how to change the stored procedure to avoid this error.
Is there a parameter to be set on the JDBC adapter that I can use, so the red flag is avoided?
Thanks for any input!

Hi Oeystein Emhjellen.
The problem is Store Procedure that has to generate always a ResultSet (or cursor). If it doesn't have a output, you have to generate an Empty ResultSet.
Like a SELECT Statement:
If there are data, SELECT get an output result but if it get nothing the SELECT Statement get a empty ResultSet.
Ask to your database team.
I hope it helps you.

Stream not found null error

Hello everybody,
I am able to embed the strobe player on a web page and play flv videos. However, if I don't let the videoplay through and refresh my web page, then I am getting "We are unable to connect to the content you've requested" error.
When the video is played all the way to the end, I can replay it without any issues.
When I set the verbose value to true, I am getting Stream not found null error instead,
It seems to me that the strobe player can stream the video from server when it is not found in local cache. If the video is not cache completely in local machine, strobe player will display "We are unable to connect to the content you've requested" error.
Is there a setting in Strobe can resolve this issue?
The flv file is loaded on Windows Media Services 2008.
Below is my embed code. It is very standard that generate from the strobe setup page
<object width="470" height="320"> <param name="movie" value="myserver/strobe/flash101/StrobeMediaPlayback.swf"></param><param name="flashvars" value="src=http%3A%2F%2Fmy.domain.com%2Fnews%2Ftest.flv&optimizeInitialIndex=false"></par am><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="myserver/strobe/flash101/StrobeMediaPlayback.swf" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="470" height="320" flashvars="src=http%3A%2F%2Fmy.domain.com%2Fnews%2Ftest.flv&optimizeInitialIndex=false">< /embed></object>
Any help would be greatly appreciated.

Hi,
On what browser does exhibit this behavior?
Can you provide a link to the video? You can PM it, if you want to keep it secret.
You might want to raise an issue at http://bugs.adobe.com/jira/browse/ST . It will allow us to prioritize and investigate it easier.
p.s. Optimize initial index works with MBR streams, you don't need it.

Visual Web ICEfaces - 'library must not be null' error

Hi Everyone...
I installed the following plugins 'ICEfaces Run-Time Libraries' and 'VisualWeb ICEfaces'. I restarted the IDE and went on to create a 'Web Application'. I selected 'Visual Web ICEfaces' in the famework option and clicked on 'finish'. As the progress bar hits 75%, I am getting a message that says 'library must not be null' and there is no further progress beyond 75%. When I click on the 'library' tab, I can see 'ICEfaces Run-Time 1.8.2', so I dont understand why I am getting a 'library must not be null' error. Any idea why I am getting this?
OS: WinXP Professional
IDE: Netbeans 6.5.1

any clues anyone?

BlackBerry Desktop Software displays the error "Caught _com_error exception. Description(): (null): Error(): -2147319779 (0x8002801D). ErrorMessage(): Library not registered.:Source(): (null)." when attempting to synchronize organizer data

BlackBerry Desktop Software displays the error "Caught _com_error exception. Description(): (null): Error(): -2147319779 (0x8002801D). ErrorMessage(): Library not registered.ource(): (null)." when attempting to synchronize organizer data.Can someone help me with this?

Tried clean wipe and reinstall. Immediately after reinstall of DM, in setting up my 9900 "for the first time", I received the following error message...
"Either there is no default email client or the current mail client cannot fulfill the messaging request. Please open Microsoft Outlook and set it as the default mail client."
I opened Outlook 2013 and checked that it was the default mail client. It was already.
After going in and clicking to confirm default email client, I was allowed to proceed to configure organizer sync settings. I configured memo only (one way from device). I then received the same error message that I was receiving (per my original post in the last message). I've previously tried configuring only one type of organizer sync and not one of them completed a successful sync, so it can't be a bad entry in the calendar or contacts. I also tried deleting CICAL entries for all of email addresses other than my primary one. No difference. Also, prior to setup and sync, I confirmed that my 9900 was not on wireless sync.
I was hoping that this was an old issue and I could use one of the old work-arounds, so if anyone has any ideas for something else to try, please let me know.
In the mean time, I have to assume that it's something that's changed with Outlook 2013 (particularly given the new error message I reported above. I hope that someone at RIM is aware of these error messages and is working on a compatibility fix for Office 2013.
Thanks in advance,

Page not found errors

I am stuck with the following error "page not found" when i click on my link. I am trying to use the cgicmd.dat.
In the .dat file:
report: server=Rep60.sony.com userid=#####/#####@dwhs report=%1 %*
In the HTML code:
href="http://sddb5.station.sony.com/dev60gci/rwcgi60.exe/report?by_day.RDF&reptype=hrts_unique_users&destype=cache&desformat=HTML"
Again when i click on the link i get page not found errors. ANy clues?
null

hello,
did you try to specify the whole URL for testing ... without using the cgicmd.dat ?
and i hope the part in the URL .../dev60gci/rw... is just a typo in this message ;-) it should say .../dev60cgi/...
regards,
the oracle reports team<HR></BLOCKQUOTE>
Yes it is working when i pass the whole thing throught the html string. What i am trying to avoid is the db autho betting passed. I would like to require none what so ever and let the Apache Server do that bidding. But i understand that i have to use the .dat file and i can't make it work for me.
null

Is not null and null join

Hi, I am trying to properly display a list of tasks for a project however without a join to the project number (which I was aware of) and the employee table, I get over 500 results.
The task can be created without a employee assigned to it so therefore the page does not require the field to be filled in.
Here is the SQL code, any does anyone have any ideas?
select
    pd.pk_proj_detail_id    "Task Number",
    pd.task_title           "Task Title",
    pd.DETAIL_STATUS        "Task Status",
    pm.name                 "Associated Project",
    pps.last_name||', '||pps.first_name||', '||pps.middle_initial||'.' "Assigned Employee",
    pd.TRACKIT_NUMBER       "TrackIt! Number",
    pd.CREATEBY_DATE        "Date Entered",
    pd.DATE_BEGIN           "Date Began",
    pd.ESTIMATED_DATE       "Estimated Completion Date",
    pd.DATE_END             "Date Completed"
from
    PROTRAC_DETAIL pd,
    protrac_master pm,
    cobr.vw_pps_payroll pps,
    resources r
where
    pd.fk_proj_master_id = pm.PK_PROJ_MASTER_ID
    and r.fk_master_id = pm.PK_PROJ_MASTER_ID
    and (r.emp_id = pps.emple_no
        or r.emp_id is null)

It's 10g r2 with Application Express 3.1.0.00.32

'UIComponent is null' error while opening a tab in ADF

Hi,
I am using JDeveloper 11.1.1.5.0
I am navigating from one ADF page to other in my ADF task flow. 2nd ADF page is having multiple tabs with showDetailItem. My requirement is that i need to open a particular tab in 2nd page from 1st page
(1st page) ---> (2nd page) (here a particular tab should open)
I have made use of NavigationHandler in my code which is working fine. But when I am trying to open a tab during navigation, I am getting 'UIComponent is null' error. below is the code I am using
    public void openDataTab(ActionEvent actionEvent) {
        NavigationHandler nvHndlr = FacesContext.getCurrentInstance().getApplication().getNavigationHandler();
        nvHndlr.handleNavigation(FacesContext.getCurrentInstance(), null, "showOverview");
        AdfFacesContext.getCurrentInstance().addPartialTarget(panelTabbed); //getting 'UIComponent is null' error here
        dataTab.setDisclosed(true);
        transactionTab.setDisclosed(false);
    }I am getting the error only for the first time. From second time onwards, the functionality is working fine.
Please let me know how to resolve this error.
regards,
Rajan

Hi,
this code should not be used for navigation as it bypasses JSF lifecycle methods
//don't use
NavigationHandler nvHndlr = FacesContext.getCurrentInstance().getApplication().getNavigationHandler();
nvHndlr.handleNavigation(FacesContext.getCurrentInstance(), null, "showOverview");
To solve your issue, add a managed bean in pageFlowScope or use an attribute inpageFlowScope that you use to identify the tab to be opened. Then in the second page, use the "disclosed" property on the showdetailItems to evaluate the pageFlowScope information and then return true or false respectively. The tab that evaluates to "true" will be opened.
Frank
Ps.: JSF component trees are created upon render response phase, which is why your programmatic attempt (which happens during invoke_application phase fails

BOOLEAN DEFAULT FALSE NOT NULL for key-column

Hello,
These statements show an unexpected behavior when a column is added to a table as 'BOOLEAN DEFAULT FALSE NOT NULL' and added afterward to the table's primary key column set:
create table test_1 (a char(1))
insert into test_1 values('A')
alter table test_1 add b boolean default false not null
alter table test_1 add primary key (a,b)
create table test_2 (a char(1), b boolean default false not null)
insert into test_2 (a) values('A')
alter table test_2 add foreign key f_test_1 (a,b) references test_1 (a,b)
      -> [350]: Referential integrity violated
update test_1 set b=false
alter table test_2 add foreign key f_test_1 (a,b) references test_1 (a,b)
      -> success
delete from test_2
delete from test_1
insert into test_1 (a,b) values('A',false)
insert into test_2 (a) values('A')
      -> success
I think the error message '[350] Referential integrity violated' should not happen because the column 'b' really contains 'false'. But there obviously seem to be a difference before and after setting the column 'b' explicitly to 'false'. I can imagine that this depends on the way how the index for the primary key is updated. Probably the index is not properly updated in this context(?)
Gabriel

Hi Gabriel,
you're right, this is a bug and indeed seems to caused by the way the DEFAULT boolean is stored in the page.
(There is no separate index for the primary key in MaxDB as all data is stored in B*trees - basically the table is the primary key).
This is how the record looks like when column b is 'false' only due to the change of the DEFAULT value:
ROOT/LEAF 460 perm       entries : 1         [block 0]
     bottom : 93         filevers: 14888     convvers: 83
                                              writecnt: 1
1: (pos 00081)
00001      recLen      : 12                recKeyLen   : 4
00005      recVarcolOff: 0                 recVarcolCnt: 0
     record
      1 2 3 4 5 6 7 8 9 10 11 12
     81 82 83 84 85 86 87 88 89 90 91 92
dec: 12 0 4 0 0 0 0 0 32 65 0 0
hex: 0C 00 04 00 00 00 00 00 20 41 00 00
chr:                             A
And this is how it looks like after the explicit UPDATE:
ROOT/LEAF 460 perm       entries : 1         [block 0]
     bottom : 93         filevers: 14888     convvers: 84
                                              writecnt: 2
1: (pos 00081)
00001      recLen      : 11                recKeyLen   : 3
00005      recVarcolOff: 0                 recVarcolCnt: 0
     record
      1 2 3 4 5 6 7 8 9 10 11
     81 82 83 84 85 86 87 88 89 90 91
dec: 11 0 3 0 0 0 0 0 32 65 0
hex: 0B 00 03 00 00 00 00 00 20 41 00
chr:                             A
Little difference but this leads to the problems during the foreign key validation.
I'll inform the developers next week about this.
As a workaround you'll have to explicitly update the columns for which you change the default setting.
regards,
Lars

Alter Table Add column not null default value

I want to add two columns to a table with not null and default as 0 for both columns
Can i write the whole in one statement or do i have to split statement
I tried this, but didn't work

COMB_ORD_FLG NUMBER(5,0) default 0 not null,

How can i modify the code?

Empty string in NOT NULL column

I'm migrating data to Oracle 9i from a database engine that supports emtpy strings in column with NOT NULL specified in the DDL. I would have thought Oracle would support this, but any attempt to put empty string data into a column created with NOT NULL is returning a 'column does not support nulls'-type error.
Is there an option to allow this, or does Oracle simply not support this and assumes blank is null?
Thanks

I would have thought Oracle would support this, but any attempt to put empty string data into a column created with NOT NULL is returning a 'column does not support nulls'-type error.In Oracle Null means null nothing not even an empty String.
Yes DB's like Ingress supports this. But I think Oracle is right.
Is there an option to allow this, or does Oracle simply not support this and assumes blank is null?I am not aware of any options as it is against the basic principles.
you can find work arounds to do the migration. But storing a blank NO.
Good Luck
