Updating field in table data provider

Question

Hi. I'm trying to get familiar with JSC2 (plus being new to Java) and am running into what must be simple problems, but I can't seem to find a solution. Here is the code behind a login button on a page. The user will enter an email address and a password, then click a login button. I use the email address to see if they are in the cached row set, then if they are there I want to increment a column in the table to indicate that they are logged in. Here's where I run into problems. I'm trying to use syntax that I'm finding in various tutorials and sample code, but it keeps telling me that it can't find the symbol "setValue" and I don't get it.
Here's my code for the button:
public String loginBtn_action() {
try {
RowKey userRowKey = tblusersDataProvider.findFirst
(new String [] { "tblUSERS.EMAILADDRESS", "tblUSERS.PASSWORD" },
new Object [] { useridFld.getText(), passwordFld.getText() });
if (userRowKey == null) {
error ("Invalid userid or password! Try again!");
return null;
else {
int userActive = getSessionBean1().getTblusersRowSet().getInt("tblUSERS.ACTIVE");
if (userActive == 0) {
userActive = userActive + 1;
userRowKey = tblusersDataProvider.getCursorRow();
try {
// Update Info in DB Rowset
FieldKey activeFldKey = tblusersDataProvider.getFieldKey("tblUSERS.ACTIVE");
tblusersDataProvider.setCursorRow(userRowKey);
// Store Value in Session
tblusersDataProvider.setValue(activeFldKey, userRowKey, userActive);
tblusersDataProvider.commitChanges();
catch (Exception ex) {
log ("Active Update Error:" + useridFld.getText() + " " + passwordFld.getText(), ex);
error ("Database Error during log in! (active update): " + ex.getMessage());
return "pgMenu";
} else {
error ("This userid is already logged in!! Multiple login's aren't allowed!");
log ("Multiple login attempt: " + useridFld.getText());
return null;
return null;
catch (Exception exx) {
log ("Error during user DB access: " + exx.getMessage());
error ("Error during userDB access: " + exx.getMessage());
return null;
}

The error message that you are giving is telling you, in a round about way, that there is no wetValue method for the data provider that takes a field key, row key, int.
If you type
tblusersDataProvider.setValue(
and then press ctrl-space, a list pops up to show all the setValue methods and what types of arguments they take.
You will see that they take Object as the last argument . None of them take an int.
To fix your problem, try something like this
tblusersDataProvider.setValue(activeFldKey, userRowKey, (Integer) Integer.valueOf(userActive));
