In all places you reference your callback, including the Async
Interface, make it's

Hi,
Thanks for the reply. I have changed the following things you asked me
to do.
This is the code of my onSuceess Method
public void onSuccess(ArrayListString result) {

You can simplify that a lot by just doing:
String firstResult = result.get(0);
You have a lot of conversions that are uncessceary.
But judging by the error you're str has no elements in it. What you
want to check is
result.size() 0

Hi,
I apologize because this topic is again n again asked on the forum,
but after reading the topics I was not able to get an answer to my
problem.
I am connecting to a server and trying to display an sql query on the
browser. Here is my server side code:

Rahul,
Based on your query (select SourceTableName from SourceTables), I
would guess that your result set would contain a single column with
string data (char or varchar in SQL). If that's correct, then your
loop should look more like this:
while (rs.next()) {
rowArray.add(rs.getString(1));
}
while(rs.next()) is fine and pretty standard way to go through.
I'm confused by how you are adding the data to the ArrayList though.
You get your resultSet which judging by your query should be
TableNames, which I assume are Strings?. But you're getting it out as
an INT then converting to a

Hi Sean,
Thanks for replying.
I understood what you are trying to say.
@Chad can you elborate on Your code would only work if the
SourceTableName column in the
SourceTables table is of an integer type. My column name is
presently an varchar type

Well, just that. The code you originally posted showed you trying to
retrieve integer data from your result set, but your table contains
string type data so your code wouldn't have worked. Now, the error you
posted looks like you are trying to cast your result to a String in
your onSuccess
