I used JTable to update records in a table. In the following code, I am getting
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
exception in the line :
table = new JTable(this);


However, this is happening ONLY for the table 'Triangle' and not for the other tables. What could be wrong ???

Can you perhaps show the entire stack trace? There is something in the table model, but without that code or the stack trace it's impossible to know what.

This is the only line that is shown as error while executing that class file. :-(

But without the stack trace we still can't see what exactly is going wrong. There are quite a lot of method calls from the JTable constructors that it's hard to see what exactly goes wrong just by looking at this code.

This is the complete code of the .java file. I have a table Triangle in Microsoft access DB. It has 14 columns

the culprit is likely to be in this bit



in particular these 2 lines
pos = colname.indexOf("_");
colname = colname.substring(0,pos) + " " + colname.substring(pos+1) ;

if there is not a '_' in colname, pos = -1, and you will get the exception you see.

try it this way, and see if it fixes the problem

Thanks a lot.
It is working now.
