Batch Update Exception

Hi
I am using batch updating (i.e. stmt.addBatch(sqlString), executeBatch(), etc.)
my code is:
int id = 0;
String sqlStr = "";
...
...
//createNewStatement is a customize method for creating a new statement.
Statement insertStmt = db.createNewStatement();
while(!(idVector.isEmpty())){
id = idVector.firstElement();
sqlStr = "INSERT INTO ids VALUES ('" + id + "')";
insertStmt.addBatch(sqlStr);

}
...
insertStmt.executeBatch();
insertStmt.close();
...
My question is: if somehow the id had a problem when it is executing the batch, how could I output the id that had the problem and continue on processing the others after it? Is there someway in retreiving the error from the executeBatch? I have tried putting it in a try-catch block, it doesn't work. I tried this:
try{
//execute batch
}catch(BatchUpdateException b){
System.err.println("SQLException: " + b.getMessage());
System.err.println("SQLState: " + b.getSQLState());
System.err.println("Message: " + b.getMessage());
}
and all it does is give me a "General Error" message.
Any help would be greatly appreciated. Thank you.
Allen

Although every driver handles this differently, when I was using the Oracle thin drivers it was an all or nothing deal. If there was one exceptioin in the thousands of batched updates, then all would fail and you could not find out at which statement it failed. Don't know about the other drivers, but I assume they are similar.
