Applet selection return false?

Hi,
In the spec, there may be cases that the applet select() method return false. I am suspecting which cases cause the applet return false?
In my mind, before selection, the applet is in idle state so that it should be ready to be selected. Hence invoking its select() method should always return true in all cases.
regards,
Hoang Long

For some applicative reasons, an applet may refuse to be selected:
- it could be a "server" applet, whose only purpose is to provide a shareable object to other applets
- the applet may have been "invalidated" by the card issuer (expiration date, theft/loss, etc...)
It's up to the application provider to define the cases where an applet refuses selection.

Bug Report: ResultSet.isLast() returns false when queries return zero rows

When calling the method isLast() on a resultset that contains zero (0) rows, false is returned. If a resultset contains no rows, isLast() should return true because returning false would indicate that there are more rows to be retrieved.
Try the following Java source:
import java.io.*;
import java.sql.*;
import java.util.*;
import oracle.jdbc.driver.*;
public class Test2 {
public static void main (String [] args) throws Exception {
Connection conn = null;
String jdbcURL = "jdbc:oracle:thin:@" +

"(PROTOCOL=tcp)(PORT=<DB port number>))"+
"(CONNECT_DATA=(SID=<Oracle DB instance>)))";
String userId = "userid";
String password = "password";
try{
// Load the Oracle JDBC Driver and register it.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// *** The following statement creates a database connection object

// <driver>, can be 'thin' or 'oci8'
// <db connect string>, is a Net8 name-value, denoting the TNSNAMES entry
conn = DriverManager.getConnection(jdbcURL, userId, password);
} catch(SQLException ex){ //Trap SQL errors

//conn = new OracleDriver().defaultConnection(); // Connect to Oracle 8i (8.1.7), use Oracle thin client.
PreparedStatement ps = conn.prepareStatement("select 'a' from dual where ? = ?", ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY); // Use any query that will return zero rows.
ps.setInt(1, 1); // Set the params so that the query returns 0 rows.
ps.setInt(2, 2);
ResultSet rs = ps.executeQuery();
System.out.println("1. Last here? " + rs.isLast());
while (rs.next()) {
// do whatever
System.out.println("2. Last here? " + rs.isLast());
ps.close();
rs.close();
EXPECTED RESULT -
1. Last here? true
2. Last here? true
ACTUAL RESULT -
1. Last here? false
2. Last here? false
This happens to me on Oracle 9.2.0.1.0.

387561,
For your information, I discovered this problem from
running a query that did access an actual DB table.
Try it and let me know.I did say I was only guessing, and yes, I did try it (after I posted my reply, and before I read yours). And I did check the query plan for the queries I tried -- to verify that they were actually doing some database "gets".
In any case, the usual way that I determine whether a "ResultSet" is empty is when the very first invocation of method "next()" returns 'false'. Is that not sufficient for you?
Good Luck,
Avi.

A strange applet selection fail problem

Hi, All. I am trying to implement the RSA encryption and decryption using rmi. I use the RSA implementation sample code in the previous post and the RMIPurse sample code in the package (3.0.2 classic ) for testing. However, after I add some initialization codes into the PurseImpl class, I got the "applet selection failed" error.
The code that I modified based on RMIPurse

That's strange. because without the initialization codes in try/catch block, there is no problem to select the applet. Can anyone help?

I have exactly the same problem when calling (trying to) any applets method. Where are these parameters to be turned on?

Installer Applet Selection Problem

Dear All,
I am having a little problem in installation of applet on the actual java card.
I have giesecke & Devrient 3.0 Contactless Java Card.
I was having problem in installing my applet. So i have removed all the apdus from the script and left only applet selection apdu as below:

The result when i try to send this to the card using apdutool:

What could be going wrong, will the installer applet id be different for different cards.
I know there has seen a similar post on this forum but the problem as prescribed in the replies to that post i cannot use JCOP tools right now as i am unable to find any download related to JCOPS.
Any help will be appreciated.

The ResultSet.next() returns false....

Hai,
I am working on jdbc. The connection credentials all correct, and its getting connected to the sybase without any problems. But I am not able to perform any 'select' or "update" statements...There are no exception or any errors...But the ResultSet.next() returns false and executeUpdate returns 0 . .
I think you can help me.....Thanks...

Yes the query is sameAs already pointed out, there are ONLY two possibilities.
1. The query is not the same
2. The database is not the same.
You are making assumptions about what is going on and then drawing conclusions.
You need to understand that you assumptions are wrong. So it doesn't matter what conclusion you draw.
In terms of why the query isn't the same there could be any number of reasons but usually it is because you are passing in data and that data isn't what you think (assume) it is. It can also be that you are constructing the SQL and that construction is different. It could be that the environment that you use to test as settings which impact SQL.

In a javascript function invoked from an onsubmit handler, if the function returns false, the form is still submitted. If I find an error in a form, how do I cancel the submit?

HTML form has: action="/TTFFRP/addlicense.rex" method="get" onsubmit="validate_data();"
validate_data is defined in tags:
function validate_data()
alert('in validate routine');
if (document.getElementById('custname').value == '')
alert('Customer name must not be blank; put in name of organization licensing File RePackager');
return false;
}

How do I find a word in all my document, return false if it's not in there.

Hi,
I struggle with something that should be easy, and didn't find any answer on this forum.
I have a list of word that I want to search in a 300 pages catalogue in InDesign. I'd like to know how can i:
1) Look for the word
2) Return true if it's in the document
3) Return false if it's not
FYI, the words i'm searching are product code, so if they're not in the catalogue, the product isn't in the catalogue.
Thanks a lot,
Olivier

Hi Oliver,
Use this,
var doc = app.documents;
app.findTextPreferences = NothingEnum.nothing;
app.changeTextPreferences = NothingEnum.nothing;
app.findTextPreferences.findWhat = "Text";
var foundtext = app.activeDocument.stories.everyItem().paragraphs.everyItem().findText();
for (var i=0;i<foundtext.length;i++){
        if (foundtext[i].length != 0){
            alert("True");
        else{
            alert("False")
app.findTextPreferences = NothingEnum.nothing;
app.changeTextPreferences = NothingEnum.nothing;

(New to C# here) What is the best way to return false in a function if it cannot be executed successfully?

In Javascript or PHP you can have a function that could return, for example, a string in case of success and false in case of failure.
I've noticed (in the few days I've been learning C#) that you need to define a type of value that the function will return, so you need to return that type of value but in case of failure you can't return false.
What is the best way to achieve this behavior and is there an example I can see?
Thank you in advance,
Juan

Juan, be aware that returning null won't work with value types, such as an int, which can't be null. You'd have to use a nullable value type. A nullable int would be declared with a "?", such as:
int? someOtherFunction(int param)
if(something goes great)
return param * 42;
return null;
And you have to use it like this:
int? result = someOtherFunction(666);
if (result != null) // you can also use result.HasValue
// it worked, do something with the result
// if you're doing math with the result, no problem
int x = result * 2;
// but if you're assigning it to another an int, you need to use this syntax
int y = result.Value;
Before nullable value types came along, for a method that returned an int, I'd use a value of something that wouldn't normally be returned by that method to indicate failure, such as a -1.
~~Bonnie DeWitt [C# MVP]
That's something very very important to keep in mind. Can save you from a lot of headaches!
So if you have an int function and it might return NULL, if you are doing Math with the return value you can use it directly, but if you're assigning it to another variable you have to use .Value?
Thanks

ExternalInterface.available returns false on a Mac

Hi there!
I'm triyng to get the browsers back-button to work with my
flash site. The general principle is this:
There is an index.html page containing an (not yet) hidden
Iframe and the flash movie.
The Iframe contains page A, which starts with JavaScript
calling a BACK-function on the index-page.
The BACK-function triggers an AS-function in the flash-movie
that activates its own back-button, and then changes the URL of the
Iframe to Page B. This causes a new History to be added to the
browser.
The flash movie now contains 5 frames (labeled in the middle
of the stage) and two navigation buttons: back (Terug) and forward
(Verder). Those buttons do exactly what you'd expect them to do
(prevFrame and nextFrame).
On a PC (IE) this seems to work pretty well. But on a mac
nothing seems to work propperly.
I've got a testpage at:
http://www.multimediamatters.nl/test
Here's the code I have on the first frame.
stop();
_root.terug.onRelease = function(){
prevFrame();
terugF = function(){
trace(_root._currentframe);
if (_root._currentframe > 1){
_root.terug.onRelease();
else {
_root.getURL("javascript::history.go(-2)");
import flash.external.*;
var isAvailable:Boolean = ExternalInterface.available;
var txtField2:TextField = this.createTextField("txtField",
this.getNextHighestDepth(), 300, 0, 200, 50);
txtField2.border = true;
txtField2.text = "ExternalInterface.available =
"+isAvailable.toString();
var methodName:String = "goHome";
var instance:Object = null;
var method:Function = terugF;
var wasSuccessful:Boolean =
ExternalInterface.addCallback(methodName, instance, method);
var txtField:TextField = this.createTextField("txtField",
this.getNextHighestDepth(), 0, 0, 200, 50);
txtField.border = true;
txtField.text = "ExternalInterface.addCallback =
"+wasSuccessful.toString();
Somehow the ExternalInterface doesn't seem to get loaded. Any
suggestions to solve this?
Thanks in advance.
Yours,
Andra
P.S.
The condition
if (_root._currentframe > 1){ doesn't work on a PC
either. It always calls
_root.terug.onRelease(). I can't figure out why...

Woops!! I guess I wasn't paying enough attention...
On a mac using Internet Explorer, both
ExternalInterface.available and
ExternalInterface.addCallback return false. Using the back
button does reload Page A into the Iframe, but doesn't execute any
AS-functions.
Using Safari, they both return true. However, using the back
button reloads the entire index.html instead of loading Page A back
into the Iframe. This means the flash-movie is reloaded aswell, so
you're automatically back at frame 1.
Is there any way I could get this working properly?
Yours,
Andra

Webutil_file_transfer.as_to_client_with_progress returns false

Hi,
I have the following problem: I want to transfer a file from the application server to the client. I use the following code:
DECLARE
l_cache_filename VARCHAR2(150) := 'Q:\OracleReportsTemp\123.html';
l_report_desname VARCHAR2(150) := 'C:\pcedownload\456.html';
BEGIN
IF NOT webutil_file_transfer.is_as_readable(l_cache_filename)
THEN
message('error in configuration');
ELSE
IF NOT webutil_file_transfer.as_to_client_with_progress(l_report_desname, l_cache_filename, 'Transferring to '||l_report_desname, 'Transferring to '||l_report_desname)
THEN
message('error while transferring');
END IF;
END IF;
END;
The file Q:\OracleReportsTemp\123.html exists on the application server and the directory C:\pcedownload exists on the client PC.
This is the extract from webutil.cfg from the application server:
transfer.database.enabled=FALSE
transfer.appsrv.enabled=TRUE
transfer.appsrv.workAreaRoot=Q:\OracleReportsTemp
transfer.appsrv.accessControl=TRUE
transfer.appsrv.read.1=Q:\OracleReportsTemp
Although this code works fine on my local OC4J, webutil_file_transfer.as_to_client_with_progress always return FALSE on the Application Server. The function webutil_file_transfer.is_as_readable returns true on both environments. Other webutil function such as client_text_io also work fine on both environments.
Versions:
Forms 10g Release 2
Application Server 10g Release2 using OID and SSL
Webutil 1.0.6
Jinitiator 1.3.1.22

Hi,
You can try as follows in your webutil.cfg file:
transfer.database.enabled=TRUE
transfer.appsrv.enabled=TRUE
transfer.appsrv.workAreaRoot=
transfer.appsrv.accessControl=FALSE

How to Check for Default Applet Selection

Hello all,
I'm new to the Java Card world, so I'll warn you in advance my questions will be basic. I appreciate your willingness to help us newbies out.
I've been given a smart card and applets to dissect an reverse engineer. Currently, Applet 1 is loaded onto the card. I've tried installing the Wallet demo applet onto the card, and by all accounts it appears the applet has loaded. However, I cannot select the Wallet demo applet, but I can send APDU commands to Applet 1.
How can I check to see if Applet 1 is selected by default? My thought is that Applet 1, or Global Platform (2.1.1) has locked down selecting another applet.
Any suggestions are greatly appreciated.
Thanks,
Collin

Ok, but as per specification applet selection should still be handed by the OS before it hands them to the default selected Applet. The default selected Applet should not be able to block SELECT by Name. It does however receive the APDU if no selection could take place.
If this card has Global Platform installed you could post the output of some GET INFO APDU's to see what is installed on the card. You will need to authenticate to the cardmanager to get permission though.

SELECT returns no result when there is a default namespace definition inXML

Hi,
I have a problem that my select doesn't return any result when there is a default namespace definition in my XML file.
I'm using oracle 11g release 1
XML file stored as a binary XML:
<SIMS xmlns="http://sims.ics.muni.cz" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://sims.ics.muni.cz jh_sims_matricni_vystupy_or.xsd">
<Vystup Datum="2006-07-18" Typ="2" Nazev="Poslední etapy" PocetStudentu="1" PocetStudii="2">
<Student RodneCislo="8001011001">
<Jmeno>Petr</Jmeno>
</Student>
</Vystup>
</SIMS>
This select return no result:
SELECT student.jmeno FROM jh_sims_bin_no_schema s, XMLTable('/SIMS/Vystup/Student' PASSING s.OBJECT_VALUE COLUMNS jmeno VARCHAR2(10) PATH 'Jmeno') student
When I remove default namespace definition (xmlns="http://sims.ics.muni.cz") everything works fine and the same SELECT returns "Petr". Also when the file is stored in object relational storage everything works fine!
<SIMS xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://sims.ics.muni.cz jh_sims_matricni_vystupy_or.xsd">
<Vystup Datum="2006-07-18" Typ="2" Nazev="Poslední etapy" PocetStudentu="1" PocetStudii="2">
<Student RodneCislo="8001011001">
<Jmeno>Petr</Jmeno>
</Student>
</Vystup>
</SIMS>
Thanks for any help!

Hi Jan,
You need to specify the default namespace of the document in the XMLNamespaces clause :
SELECT student.jmeno
FROM jh_sims_bin_no_schema s,
     XMLTable(
      XMLNamespaces(default 'http://sims.ics.muni.cz'),
      '/SIMS/Vystup/Student'
      PASSING s.OBJECT_VALUE
      COLUMNS jmeno VARCHAR2(10) PATH 'Jmeno'
     ) student
;

The mkdir() function in java returning false. Why?

I am trying to create the folder archive under the following directory structure:
E:/preweb/CATest/DL/Zipra Internal/EventCompletion/html/archive/
using the boolean mkdir() function in java.
Though the folder archive does not exist under html folder, still the function is returning false.
Canm someone let me know why?

And you have checked that by using
File file =// E:/preweb/CATest/DL/Zipra Internal/EventCompletion/html/archive/
Sys.out.println( file.getParentFile().exists() );

File.exists() returns false for existing file, help :)

Hi all,
I'm having the STRANGEST behavior... I'm working on a simple DNS management system, and before I overwrite a zone file, I want to check if it exists... but exists() is returning false even when the file exists.
Here is my code snippet:
finest( "Checking the existance of "+filename ) ;
File zoneFile = new File( filename ) ;
if ( zoneFile.exists() ) {
    finest( "Zone File "+zoneFile+" already exists." ) ;
    throw( new ZoneFileExistsException( fqdn ) ) ;
else {
    finest( "Creating Zone File "+zoneFile ) ;
    ...It's producing this in the log (I cut off the timestamp parts):
Checking the existance of /opt/DNS/db.testingbutler222.com
Creating Zone File /opt/DNS/db.testingbutler222.com
but...
# ls -l /opt/DNS/db.testingbutler222.com
-rw-r--r-- 1 root other 733 Aug 27 19:23 /opt/DNS/db.testingbutler222.com
So... as you can see, the file CLEARLY exists... what the heck am I doing wrong or misunderstanding? This can't really be a bug in File, can it?
Kenny Smith

Hi,
Thanks for your response, but as I showed in my first post, I'm using absolute paths. My log file contains this:
Checking the existance of /opt/DNS/db.testbutler222.com...
Existance of /opt/DNS/db.testbutler222.com=false
# ls -l /opt/DNS/db.testbutler222.com
-rw-r--r-- 1 root other 695 Aug 29 12:17 /opt/DNS/db.testbutler222.com
I don't understand what is happening... I wrote a separate class that just tests the existance of a file, and that one is reporting the existance correctly.... (the source code is found in the second post above) I don't understand why my servlet code can see the file.
I have jakarta-tomcat running as root, and the file I'm checking was created by the same servlet. I've double checked permissions and such, just to make sure it wasn't that.. but it's still not working.
I even added code to create a FileReader from the file, that way if it throws a FileNotFoundException, I would know the file doesn't exist... and even though the file does exist, it throws the exception. :(
