an array in a hashtable

[beebob]

Dear all,

I have just changed my jdk, from JDK 1.5.0 to JDK 1.6.0, and also changed my Netbeans, from NB 4.0 to NB 5.0. Now, I have got a problem with my web application. Can anyone tell me, what is wrong with my code below:

-------------------

Hashtable resultHT = new Hashtable();
try {
OpenConnection();
stmt = con.createStatement();
stmt.execute(sqlQuery);
rs = stmt.getResultSet();

ResultSetMetaData rsmd = rs.getMetaData();
int numCols = rsmd.getColumnCount();
int baris = 1;
String strIsiKolom = new String();

while (rs.next()){
String[] isi = new String[numCols];
for (int i=1; i<= numCols; i++) {
strIsiKolom = rs.getString(i);
if (strIsiKolom.length()==0) {
strIsiKolom = "-";
isi[i-1] = strIsiKolom;
} else {
isi[i-1] = strIsiKolom;
}
}

resultHT.put(new Integer(baris), isi);
baris = baris + 1;
}

-------------------

When I used my NB 4.0 + JDK 1.5.0, this code didn't give any problem. But now, I get an error message... something like there is no data on my hashtable. I have failed to insert anything on the hashtable.

Can anyone help me???

Thanks.

Hi,
Plz use code tags while posting code.
Use System.out.println statments to test it where it is going wrong.

Please post the exact error message you got.

But now, I get an error message... something like there is no data on my hashtable.

So you want us to give you a clear answer given your extremely vague description
of the error diagnostic: "something likere there is no data". Big deal. If you want a
clear answer from us, please give us clear details about what displayed the error
diagnostic (the compiler? the virtual machine itself?) and what exactly was displayed.
(that only takes a copy and paste action).

kind regards,

Jos
