Dynamic use of JTable

I have a JTable which holds a number of columns (these are fix). Now my
problem is that this table can change at any time by an event in the table.
I create my rows and data by a table model.
Those anyone have a idea how I can make the JTable dynamic. So I can easly change the number of rows by an event on the table itself or by a event on the Frame?
Thanks

Hi,
I can't see your problem - if you use a subclass of AbstractTableModel for your table model, which has for example n entries (perhaps hold in a Vector of Vector like DefaultTableModel does it) and you have added for example x rows, simply fireTableRowsInserted(n,n+x-1) of the table model and JTable will update its display correctly. If you delete for example row y simply fireTableRowsDeleted(y,y) - you just have to fire the correct notification message and inform the listeners of the table model about that, what you have done, and the display will keep updated correctly. If you change the whole data vector but keep the structure of the table, simply fireTableDataChanged() - if the data vector and the structure of the table changes, fireTableStructureChanged() - you see, just inform the TableModelListeners about that, what you have done in the table model, and the table will be updated correctly as so the JTable itself is a TableModelListener to its model.
Perhaps you can be more specific about what your problem is

Dynamically Updating a JTable

I am developing an EPOS system using java, that uses a JTable to display the recipt, before it is printed.
I have a class for the recipt data, stored in a vector which works and using observers fires events to the gui when things are added etc. My problem comes when i try to dynamically change the tables content, my idea was to create a new table, fill it with the new data, set the scroll pane around the new table and call revalidate to show the new table.
This is possible but seems far too much work to just update a table! I would also assume the amount of extra garbage collection would require extra processing that seems pointless.
Is there another way i could do it? Ideally i just want to refresh the content in the table for each update sent by the observable.
Thanks

Make your TableModel observe your observable and update it's contents. Remember to fire the appropriate event after the update.

Dynamic USING clause in execute immediate

Hi All,
Is it possible to build a dynamic using clause in execute immediate command.
EXECUTE IMMEDIATE <dynamic query> USING <dynamic clause>;
Rgrds,
Nitin.

Hi,
The problem is I have a query in which in some scenarios I want just one column in where clause, in other scenario I need 2 columns in the where clause.
So I would have to write 2 different queries.
execute immediate 'SELECT 1 FROM DUAL WHERE 1 = :bind1' into a using 1;
execute immediate 'SELECT 1 FROM DUAL WHERE 1 = :bind1 AND 2 = :bind2' into a using 1, 2;
Is there any way I can achieve this in a single query like:
dynamic_using_str varchar2(100);
dynamic_using_str := '1';
execute immediate 'SELECT 1 FROM DUAL WHERE 1 = :bind1' into a using dynamic_using_str;
dynamic_using_str := '1, 2';
execute immediate 'SELECT 1 FROM DUAL WHERE 1 = :bind1 AND 2 = :bind2' into a using dynamic_using_str;

Want to send information in Header dynamically using HTTP adapter using post method

Hi ,
I have a requirement to send below information in http Adapter header dynamically using post method. which will be authenticated by third party system.
Authorization : WSSE realm="SDP", profile="UsernameToken", type="AppKey" X-WSSE : UsernameToken Username="XXXX", PasswordDigest="Qd0QnQn0eaAHpOiuk/0QhV+Bzdc=", Nonce="eUZZZXpSczFycXJCNVhCWU1mS3ZScldOYg==", Created="2013-09-05T02:12:21Z"
I have followed below link to create UDF
http://scn.sap.com/thread/3241568
As if now my third party system is not available while sending request I am getting 504 gateway error. is there any approach I can validate my request is working fine?
Regards,

Hi Abhay,
Correct me if I'm wrong but I think WSSE requires a SOAP Envelope. If that is the case, there are two approaches: the first one is to use SOAP Axis and the second one is just to build SOAP Envelope via Java mapping.
You also need to test it successfully externally, capture the request and replicate it in XI.
Hope this helps,
Mark

Hi,
see the link here
[https://cw.sdn.sap.com/cw/docs/DOC-37733|https://cw.sdn.sap.com/cw/docs/DOC-37733].
as advised, you create a usage group for dynamic components, add component usages to the group based on your conditions.

Insert a trademark symblol to my swf dynamicly using XML

hello there,
i am trying to insert a trademark symblol to my swf dynamicly
using XML,
i tried every thing i could "caved the xml in every format
known to man kind, wrote some AS script to replace thin join, i
tried to hard code the symble" but nothing worked.
i am running flash8.
help is needed plz.
today is the DEAD LINE.
plz.

Okay, test files are up in the following directory:
www.saffronthread.com/test
You can guess which ones are for you. I didn't deal with the
whole IE stupidness, so you my need to click on the page. But I've
got several different text fields some runtime some author
environment and sample text. Works for me on Mac and on the PC I
checked. Let me know what you find out.
As for System.useCodePage it is very seldom an actual
solution to the problem. It is a solution for when you want to be
sure that the user's Flash Plugin uses the computer's code page for
text rendering. Read the help entry for it and you will see that it
is not a solution for making sure that the most people possible
will correctly receive my text. It is more a solution for, I want
to make sure that those with Chinese operating systems are able to
correctly see the Chinese text I have encode with my special
encoding.
Most questions that get a "Oh, you must use
System.useCodePage answer" are more like, "I want to make sure that
everybody on every type of system can see my special characters."
The answer for that tends toward proper use of UTF-8 and that is my
guess for your problem. That your XML file is not being saved as
UTF-8. If System.useCodePage is helping you that tells me that your
XML editor is saving to some odd (maybe very popular, but not
UTF-8) encoding.

Dynamically use page number in form field on spawned pages?

I have a form with spawned pages. JS for spawning page(s) works fine. However, one text field on template is driving me nuts. I would like this field ("CaseNum") to dynamically display page number, since page number also corresponds to case number. On templage ("getcase"), I can calculate value for CaseNum using custom calc script (event.value = this.PageNum). But that doesn't work because every spawned page gets the same value (ie, whatever is last spawned page number). I also tried JS below, using P0.getcase.CaseNum as the field on the template in which I want the page number/case number to be displayed:
var oPage = this.pageNum;
this.getField("P" + oPage + ".getcase" + ".CaseNum").value = oPage;
But, this doesn't work either, because the field on the spawned page automatically gets the prefix of P + page number + .getcase appended to the field name. Is there any way to dynamically used page number in a form field on spawned pages? If so, how? Note that while I am trying to use a dynamic case number on spawned pages, it presents the same issue as dynamically displaying page numbers on spawned pages. I'm a JS newbie, so any help appreciated. I've searched high and low on web and in forums and couldn't find the answer. Thx.

Table to load dynamically using sqlloader.

how to specify which table to load dynamically using sqlloader. We are using sqlldr in a script as given below...
sqlldr user/pass control=/control/loader.ctl log=/log/logger.log bad=/bad/badrec.bad data=/data/d1.txt

# Write sqlplus commands to control_file.sql
echo "set head off
