[mrjillberth]

maybe you can use a

try{ }catch(ExceptionType handler){ }

[sohiabmaroof]

i use this try catch as u told but now i getting this error

exception com.sun.xml.internal.ws.api.model.ExceptionType is never thrown in body of corresponding try statement

incompatible types
  required: java.lang.Throwable
  found:    com.sun.xml.internal.ws.api.model.ExceptionType
so i tried this 
try {
         defaultTableModel.removeRow(jTable1.getSelectedRow());
     } catch (Exception e) {
     }

but its still gives me the same error:(

[NormR1]

Cross posted at http://www.java-forums.org/awt-swing/49131-java-lang-arrayindexoutofboundsexception.html

[NormR1]

incompatible types
required: java.lang.Throwable
found: com.sun.xml.internal.ws.api.model.ExceptionType

The error message says the compiler does not think you are not using the correct type.
It wants a Throwable instead of what you have there.

[sohiabmaroof]

can u please set my code given above to able it too delete the required row :( i am very mush pissed off by this error of java.lang.ArrayIndexOutOfBoundsException

[sohiabmaroof]

if you will copy this code to Ur netbeans or eclipse it will run please have a look at it i do not know how to create SSCCE .i created this and i thought that it is SSCCE where as my real code is much more complex than this one :(:(

[NormR1]

Your posted text of the error message did NOT give the source line number and show the source line where the error occurs.
Please post the full text of the error message.

[JamesCherrill]

This is very confusing.
You create a model called defaultTableModel and have lots of code that works with this model, but the model that's actually in the JTable (at least until line 51) is the completely different one whose definition begins

(new javax.swing.table.DefaultTableModel(
   new Object [][] {
    {"asdf",

[sohiabmaroof]

public void selectedCol(int row) {



//when the compiler comes to this point error occurs 
       
        defaultTableModel.removeRow(row);
        System.out.println("deleting");
      //  defaultTableModel.removeRow(jTable1.getSelectedRow());
        System.out.println("deleted");

    }

here the error comes

[NormR1]

Add a test to see if there is a row there before trying to remove it.

Print out the number of rows and the value of row before the remove call.

[JamesCherrill]

Yes, well, I didn't see any code to put any data in defaultTableModel, so I'm not surprised that trying to delete a row gives an error.

should i creat table in normal manner like
Jtable jtable=new Jtable(2,3);
i cqan create it in this way too .but the error wont go away please do some thing please:(

[sohiabmaroof]

so brither whats the solution please:(

[sohiabmaroof]

Add a test to see if there is a row there before trying to remove it.

Print out the number of rows and the value of row before the remove call.

ok i try this and tell u right away

[NormR1]

One way to keep from getting the exception is to test if there is a row and not try to remove it if it does not exist.

[sohiabmaroof]

no there is no row in jtable .how is that possible? why there is no row in jtable??? please tell me how to correct it:(

[JamesCherrill]

Please read my first post. You have two table models in your program. You should have only one. The data is is the one you display, but you try to remove from the other one, which has no data.
Norm - I don't know how to make this clearer - can you help?

[sohiabmaroof]

i created jtable in this way now but still it is giving the same error:(

Object rows[][] = { { "AMZN", "Amazon", "67 9/16" ,"DELETE","UPDATE"},
        { "AOL", "America Online", "68 3/4" ,"DELETE","UPDATE"},
        { "BOUT", "About.com", "56 3/8" ,"DELETE","UPDATE"},

    Object columns[] = {"Sr.no", "Book Title", "Author Name", "Delete", "Edit"};

[JamesCherrill]

You still have two models. You need to put all that data into defaultTableModel

[sohiabmaroof]

please edit my code please :( i dont see two modules :( please editing my code will help me understand gettting this problem solved quickly please :( i tried every thing i could :(

[sohiabmaroof]

im doomed i do not know where are two modules in my code:(

[sohiabmaroof]

You still have two models. You need to put all that data into defaultTableModel

please tell me how

[JamesCherrill]

Here's the first

javax.swing.table.DefaultTableModel defaultTableModel = new javax.swing.table.DefaultTableModel();

and this creates a second new one for your JTable

Object rows[][] = { { "AMZN", "Amazon", "67 9/16" ,"DELETE","UPDATE"},
{ "AOL", "America Online", "68 3/4" ,"DELETE","UPDATE"},
{ "BOUT", "About.com", "56 3/8" ,"DELETE","UPDATE"},
{ "CDNW", "CDnow", "4 7/16" ,"DELETE","UPDATE"},
{ "DCLK", "DoubleClick", "87 3/16" ,"DELETE","UPDATE"},
{ "EBAY", "eBay", "180 7/8","DELETE","UPDATE" },
{ "EWBX", "EarthWeb", "18 1/4" ,"DELETE","UPDATE"},
{ "MKTW", "MarketWatch", "29" ,"DELETE","UPDATE"},
{ "TGLO", "Theglobe.com", "4 15/16" ,"DELETE","UPDATE"},
{ "YHOO", "Yahoo!", "151 1/8" ,"DELETE","UPDATE"} };
Object columns[] = {"Sr.no", "Book Title", "Author Name", "Delete", "Edit"};
JTable table = new JTable(rows, columns);

You need to put all that data into defaultTableModel then do a

jTable1.setModel(defaultTableModel);

please tell me how

Use one of the "set" methods for DefaultTableModel. You can read about them in the API JavaDoc.

private void buttonPressed(JTable table, int row, int column){
        
        ButtonEditorTest btnEditorTest = (ButtonEditorTest) SwingUtilities
         .getWindowAncestor(table);
   btnEditorTest.selectedCol();

i this the second table? m i trying to delete value from this table? if so than this means that should create mouse listner in the ButtonEditorTest calss?

Here's the first

javax.swing.table.DefaultTableModel defaultTableModel = new javax.swing.table.DefaultTableModel();
