Hi,
I am having a similar problem that results in this stack trace. The funny thing is that it occurs after a session.logout/login and re-read of the object I'm trying to update. The other thing is that if I remove objects from the transaction it just happens somewhere else - on a different object/descriptor. I am attempting to upgrade from 9.03 runtime to the 10.0.3.1 builder/runtime. I am connecting to a Sybase 12.5 db.
Any ideas on this one?
Thanks,
Bret

Dear Guru's,
I am not able to solve the above issue for last couple of days.
I am newbie to the webservice
My Issue...
I am using Jdeveloper 11.1.2.4.0 Release 2
1. Using Jdev I built one small Web Service with two methods.
        While testing the Webservice...
               I passed User Id as Parameter and it successfully return the values (user id, user name and description) from fnd_user table
2. I created another application to consume the web service i created.
               1. I added the webservice SOAP and added the method.
               2. Created a jsf page and drag and drop the parameter and return values to the jsf page.
3. While executing the created jsf page I received the error message as below
"oracle.jbo.NoDefException: JBO-29114 ADFContext is not setup to process messages for this exception. Use the exception stack trace and error code to investigate the root cause of this exception. Root cause error code is JBO-25058. Error message parameters are {0=Attribute, 1=UserName, 2=UserName}"

I can hear caller but they can not hear me except when using speaker phone

First of all, make sure that your iPhone as the most recent iOS available. Check in "Settings>General>Software Update".
One other problem could be your microphone. Does it work for anything else other than a call?
Good-Luck!

Wrong number of parameters exception when using PreparedStatement

Hi,
I'm getting Wrong number of parameters exception when using a prepared statement. It's very weird. The code is:
sqlstmt="update blah1 set blah2=? where blah3=?";
myps = Conn.prepareStatement(sqlstmt);
myps.setString(1, p1);
myps.setInt(2, p2);
myps.executeUpdate(sqlstmt);
The error is:
SQLException: [IBM][CLI Driver] CLI0100E Wrong number of parameters. SQLSTATE=07001:07001
Could someone please help? Thanks
Mahdad

Hi and thanks for the reply.
Actually this is the try block...
The variable's defintions are correct.
PreparedStatement myps;
try {
sqlstmt="update blah1 set blah2=? where blah3=?";
myps = Conn.prepareStatement(sqlstmt);
myps.setString(1, blah4);
myps.setInt(2, blah5);
myps.executeUpdate(sqlstmt);
catch (SQLException e) {
System.out.println("SQLException: " + e.getMessage() + ":" + e.getSQLState());
blah6++;

Solved it on my own.
The sso from Java->ABAP was OK
I reconfigured the sso from ABAP->JAVA by creating new ABAP certificate and import it to the J2EE.

Problem in displaying Column Heading using JTable

I am using JTable component in my applet. I am trying to retrieve records from a database and want to display the same in the table using JTable component. In that procees my data is shown in the table but I am not able to display the column heading.
Please suggest.

you could user JScrollPane to show the column's head.
if you don't want to use JScrollPane ,you should use the getTableHeader() method and add the header into the pane

What exception to use for incorrect file format?

I parse a file and find out that it contains unsupported elemnet.

You are applying a general case to specificinstance
without knowing any of the details.Indeed I am. However, generally speaking, a method
that throws Exception is less-than-optimal design in
an API. I will try to illustrate my point.
Throwing an Exception does not provide any clues to
the user of your API about what might go wrong in the
method call, while throwing an
UnsupportedElementException certainly does. An
UnsupportedElementException is much more informative
to the user, while a plain Exception is not. A custom
exception in this case is implicitly clear, even
without consulting the Javadocs.Which is all true if I am writing a library. But most people do not write libraries, they write applications. In applications either exceptions are part of the process flow (explicitly caught) or they are not. The vast majority are not part of the process flow.
>
The only time you should create a custom exceptionis
when you believe it will be possible for someone todo
something intelligent with it.Are you always able to tell in advance whether the
user of you API can do something intelligent with an
exception? Can you make the supposition that the user
can never do anything meaningful with the exceptions
you throw? I am not convinced that you can, at least
not in most of the cases.One should never ever design or code solely based on the "hope" that sometime in the future someone "might" need it. Doing that leads to code bloat, code that is hard to understand and worst of all code that is never tested.
So unless there is a known need a special exception should not be created.
>
If I am creating an application that automatically
moves data via a socket and that must move thedata,
then I don't care why the socket failed to connect.I
am simply going to keep retrying until it does
connect. In this case an Exception is perfectly
acceptable.
On the other hand the same application might wantto
resolve the DNS name first and simply give up if it
can't resolve it. But still continue if the
connection timed out. In this case at least one
custom Exception is needed to differentiate between
the two failure paths.Agreed. And to make the API nice and neat, write two
meaningful custom exceptions to differentiate the
failures. :)Nope. Again that is fine for a library. It is not needed for an application. An application has a purpose which is defined by the requirements. Adding stuff when there is neither a current requirement or when there is no expected future requirement is a bad idea.
I have yet to meet a developer who can accurately predict the future. I have however met many who thought there code could be generalized for many possible imaginary cases that they conceived in their mind.
And all that extra code is never tested by QA (because there are no requirements) and causes maintenance problems down the road because it is not part of the documented infrastructure.
also it forces the user of
you API to catch all Exceptions.That is obviously non-sensical. Regardless of the
checked exception being used, you still have tocatch
it.I did not mean that you force the user of your API to
write a try-catch -block, I meant that you force the
user of your API to catch each and every exception
that inherits from java.lang.Exception. Even
RuntimeExceptions; and that can be a problem.
I have no idea what you are trying to express there.
A checked exception must be caught regardless of what type of checked exception it is. The user might break it out but only if the user expects to do something with a specific type of exception.

Exception raised using JComboBox with JUComboBoxBinding in a JTable

Hello,
I am using JDeveloper 9.0.3.1035.
I have a JTable bound to a bc4j view object. Now I want to use a JComboBox to select the value for a foreign key column in that Table. For this I have followed the HOWTO posted by Arno van der Kolk in Thread JClient - JTable and JComboBox which extends the OTN example "How to Add a JComboBox to a Cell in a JTable". This almost works fine except for one thing:
In the the ComboBox I display a String value but the view attribute is of type Number. Now when I edit the column using the ComboBox and the value of the selected entry cannot be converted to Number I get an exception like the following:
oracle.jbo.domain.DataCreationException: JBO-25009: Cannot create an object of type:oracle.jbo.domain.Number with value:030522 001
Even after this exception is raised the database record is updated with the correct number value corresponding to the selected entry when the changes are commited. The only w/a I have found so far is to display the foreign key attribute as the first column of the JComboBox but this is not what I want. This behaviour also occurs using the aforementioned OTN example with my JDev version but the sample works with JDev 9.0.2.
How can I get this to work using JDev 9.0.3?
Any help is greatly appreciated.
Regards,
Christof Breker

The Thread I was really referring to is:
[JClient] HOWTO: Using databound comboboxes (for foreign keys) in a JTable
The OTN sample can be found under:
http://otn.oracle.com/sample_code/products/jdev/jclient/jclient_table_combo_sample.html

Saves the word Null - Using jTable!!

Hi..
I am using a jTable to show data to the final user, and also i added a button which save changed made on the jTable is the user modifies it!! But, if i save it with in the ms access saves the word null when it finds an empty space.. why this happens? here is the code.. and sometimes it didn't work well on somefields, that why i use vectors, and now it is working.. but i am still wondering why if a field was empty, when i click on the save button it saved the word null.
Thanks for your attention,

Hi
Not sure what the use case is here but what I would do is to make sure when you create the employee or whatever the salary gets initialised to 0, db trigger, default etc.
instead of null (null values can be a PITA when you have to search on them)
Then all you have to do is to force a numeric input, the user can type 0 for all unassigned salaries.
This removes the problem you have of leaving the box blank and having to accept the word NULL as an input value.
