Problem about customized table in scrollpane

I put a customized table whose's header and rows have some colors into a scrollpane(row 0, 2, 4 ... is white, row 1, 3, 5... is black, for example).when the width of scrollpane is big enough, the space area on the right of the table in the viewport has the default color, If I want to set the space area's color the same as the table just as if the space area is the last column of the table(even row is white, odd row is black).
How can I do this?

Try adding a dummy column to the table. then use:
table.setAutoResizeMode(int mode)
so that only the last column is resized.

Problem of custom table model

Hi,
i m leaning JTable recently, following is an experimental code which i wrote, it has a custom table model and custom tablecellrenderer, the custom tablecellrender determine the column of # of Years greater or equal than 5 should display color green, less than 5 should display color red, it works well, however, the custom table model should be smart enough to know that the # of Years column contains numbers (which should generally be right aligned and have a particular format), it also should know that the Vegetarian column contains boolean values, which can be represented by check boxes, but it didn't, i don't know why, i have implement a getColumnClass method,
but it seems not work, have i make any mistakes? Any idea? Thanks

You need to write your custom TableCellRenderes/Editors for each type. And don't forget to register your custom renderes via myTable.setDefaultRendere().

Lock object problem on custom table

Hi all.
I am having a bit of an issue with a lock object on a home made table. We're using the UWL and a custom IView to display an extended invoice. No problem releasing the workitem lock, just the table entry lock.
I can see the lock in SM12. Tried dequeue/dequeue all RFCs from backend, no luck.
The lock is set from a custom RFC. This RFC succesfully releases the lock when used in SAPGUI, and we have an RFC enabled wrapper around it. However, once used in the portal, the locks aren't released. My suspicion is that it has to do with sessions and I can't see a way to control that since dynpro uses a connection pool IIRC.
Anyone have any ideas on how to solve this?

Small correction if you are not aware. Do not create your custom tables in APPS schema? Custom tables are supposed to created in custom schema such as XXPO and a synonym created for the table in APPS schema.
When creating an EO, you do not need to provide the schema name. You would need to enter only the table name.
Hope this helps.

Problem adding a table to scrollpane

My problems about reload table

hi guys,
i hava some problems now ,but i think they are easy for u.i need your help,thanks.
1.in my mini application i save the data of JTable in txt format.i have a File menu,and the menuitems are New , Open ,Save ,Save As ,and exit.When i trigger the New or Open events how can i know whether another table is opening and editing.if so ,i must make a dialog pop up to inquire the user whether save the editing table.
2.how can i know the editing table has been saved, so when i modified the table and trigger the Save event the table saves while the JFileChooser dialog dont pop up.
3.when i open a saved table,the blank cells display null.i want to replace the null with the String "".i tried
FileInputStream fin = new FileInputStream(filename);
InputStreamReader isr = new InputStreamReader(fin);
BufferedReader br = new BufferedReader(isr);
StringTokenizer st1 = new StringTokenizer(br.readLine(), "|");
while( st1.hasMoreTokens() )
     columnNames.addElement(st1.nextToken());
while ((aLine = br.readLine()) != null)
     StringTokenizer st2 = new StringTokenizer(aLine, "|");
     Vector row = new Vector();
     while(st2.hasMoreTokens())
     String s = st2.nextToken();
     if (s!=null)
          row.addElement(st2.nextToken());
     else
          row.addElement("");     }
data.addElement( row );
br.close();
and the table's coustructor is
model = new DefaultTableModel(data,columnNames);
table = new JTable(model);
it failed,how can i do?
Can u help me,guys?
thank you in advance.

1. This is really up to how you've programmed your application. In effect you've simply got to determine if there's a JTable in your UI (you probably know the container it will be in so just need to check its children)
2. Your table model will have to support the notion of being "updated". If your table model contains a flag that indicates whether it has been saved you can then set the flag when you save it and reset it when a table cell is updated. This table model can also save the File to which the table model was saved.
3. Are you sure your text file doesn't contain the string "null" anywhere? Null values in table models are usually rendered as the empty string anyway - perhaps the problem is with how you saved the data?
Hope this helps

Problem about custom preloader in Flex 1.5

I read the article written by Eric Anderson and test his
sample.But i met some problems.
the codes is on
http://weblogs.macromedia.com/eanderson/archives/2004/12/preloader_in_fl.cfm
I can only see the "Loading Your Application View . . . ",
but can not see "LOADED:" or "TOTAL:" in the function
setProgress().It seems that the function is never called.
What's wrong?
thanks in advance.

The setProgress() method is only called when downloading the
SWF from a
remote location. Is your SWF on a server? You also need to
clear the cache
before each download.

Problem about custom package.

Hi all,
I am a new beginner. When I tested a program in a book, the complier cannot resolve MyString class. Can you teach me how to fix it? Thanks.
Here's the code:
The code of PackageSample.class:
import com.BitC.test.*;
public class PackageSample
     public static void main(String args[])
          MyString a_MyString = new MyString();
          char str[] = {'J','a','v','a',' ','2'};
          a_MyString.setData(str);
          System.out.println(a_MyString.getData());
The code of MyString.class:
package com.BitC.test;
public class MyString
     protected char name[];
     public void setData(char i_name[])
          name = new char[i_name.length];
          System.arraycopy(i_name,0,name,0,i_name.length);
     public char[] getData()
          return name;

This link may help.
http://java.sun.com/docs/books/tutorial/java/interpack/packages.html
The class MyString is part of a package named com.BitC.test so you need a directory structure that matches - a com directory that contains a BitC directory that contains a test directory that contains the MyString.class file. In addition, the directory that contains the com directory must be in your classpath.

Custom table - delivery class?

I need to create a z-table to list the email-ids that I want to notify to, in case of program errors. Should I make the delivery class of this table 'C'? And is best practise to make the data transportable? Or should my users just enter data in each system.
I am kind of confused...Could any of you please clear me on this concept of Deliver class please. Your help is very much appreciated.
thanks!

Vishnu,
Did you try? I tried these things long back and documented the behavior
May be you tried it very long back, indeed. Atleast for releases > ECC6.0 EhP3 client-independent customizing tables prompt for WB requests.
... C, G, and E will only trigger customizing requests ....
Unfortunately you're wrong! Did you check the transaction FILE? All the tables involved are of Delv. Class 'G'; but still when you try to save a logical file it asks for a WB request, ever wondered why?
Still not convinced, check [this|https://picasaweb.google.com/lh/photo/kBwoENEIkUTsGuJUTn9Q5tMTjNZETYmyPJy0liipFm0?feat=directlink]!
Suhas Saha wrote. "Customizing TRs are raised for client-dependent tables & workbench for client-independent ones!"
This was w.r.t customizing tables & not application tables, as you were talking about customizing tables in your previous response.
I can create a table with MANDT assign delivery class A or S and can trigger workbench requests on it.
I know it does. IMHO type 'A' tables are for storing master and/or transational data & it does not make sense to transport these data. For e.g., BKPF is type 'A' & not transportable, but T001 is type 'C' & transportable.
If i want to transport the data across my landscape i would make it 'C' & not 'A'.

Event Alert on Custom Table not working

Hi
Custom table is registered in Custom schema, created synonym in apps and granted all priviliges to apps.
Creates event alert based on insert on custom table, though custom table is getting populated from concurrent program event alert seems to be not firing

Customized Table is giving Short Dump .Want to extract data in Production S

Hi ,
I have a problem in customized table .Table is giving a data after trying to access 185th record.There is some problem in the table.But I want to pull out all the data from the table..Is it possible to download it .Pls suggest..
Even If I put one select query also it is givning dump..
Pls suggest some other technique to download it..
Regards
Arun.P

Hi Arun,
Where there you are using WHERE condition in select statement while fetching the records?
if yes means check for the fields are primary key, available in WHERE condition, or else create secondary index for those
non Primary key Fields in WHERE condition.
This may help you.
Thanks and Regards,

Setting up event Alert on custom table

I appologize for placing my question in probably the wrong forum, but I know you guys are the sharpest and I'm spent on this problem.
Overview: I have a form that runs a report to print out some of the form's data. If the user wants to email that same data, after the print job is completed, the form updates a table with the output file name created by running the report. Here's where my problem comes in... I'm trying to create an event driven alert, but I get the below error when I go to save:
Event Table : REPORT_HDRS
ORACLE ID : APPS
The listed ORACLE ID is missing the event table or does not have the correct privileges to Application Object Library or Oracle Alert objects.
Please verify that the event table exists, or re-register the ORACLE ID with Application Object Library as necessary. Then re-enable (or disable)
the event alert as desired.
If the ORACLE ID is for a shared installation of an application, it may be normal for the event table to not be present.
Any ideas as to what I'm missing would be greatly appreciated.

hi,
Customizing table is
a very SPECIAL MASTER TABLE
where VERY IMPORTANT RECORDS
are maintained.
2. Such records, affect calculations / flow / logic etc .
3. Important thing about customizing table,
is that it will ask for REQUEST NUMBER,
whenever we try to add / modify any record in it.

And given the execute grant for public user.
and calling that procedure by calling the URL -- #OWNER#.download_my_file?p_file=#ID#
But im getting the below error

Can any one tell whats the problem here.
Thanks in advance

Your function apex_util.get_blob_file_src under region, the first argument must be the name of page item anywhere in your application that is of type "file browse." So if your form for uploading the blob content is on page 11 and the file browse item is "P11_FILE_NAME" then your query would look like below:
SELECT FILE_ID
     , FILE_NAME
      , CASE WHEN NVL(dbms_lob.getlength(BLOB_CONTENT),0) = 0
       THEN NULL
        ELSE
              CASE WHEN attach_mimetype like 'image%'
            THEN '<img src="'||apex_util.get_blob_file_src('P11_FILE_NAME',id)||'" />'
            ELSE
                 '<a href="'||apex_util.get_blob_file_src('P11_FILE_NAME',id)||'">Download</a>'
           end
       END new_img
    FROM TABLE_NAME
GET_BLOB_FILE_SRC FunctionAs an alternative to using the built-in methods of providing a download link, you can use the APEX_UTIL.GET_BLOB_FILE_SRC function. One advantage of this approach, is the ability to more specifically format the display of the image (with height and width tags). Please note that this approach is only valid if called from a valid Oracle Application Express session. Also, this method requires that the parameters that describe the BLOB to be listed as the format of a valid item within the application. That item is then referenced by the function.>
