How to convert perl object into json string
===

I tried lot of time to convert perl object into JSON String. But still i couldn't found. i used JSYNC. But i saw it has some issues. then i use JSON module in perl.
This is my code.<br/>

    my $accountData = AccountsData ->new();
    $accountData->userAccountsDetail(@userAccData);
    $accountData->creditCardDetail(@userCrData);
    my $json = to_json($accountData,{allow_blessed=>1,convert_blessed=>1});
    print $json."\n";

When i run the code it prints `null`.Is there any mistake i have done ?
