Applet runs via JCOP shell, but not from CardReader

Hi,
I'm completely new to JavaCard, JCOP and Eclipse, so maybe this is a stupid question. But I just need the answer.
I created a simple javacard applet just to get known to all this new stuff. Now I am able to debug my applet in the Eclipse environment debugger and run it in my test hardware. When I run it (on the OMNIKEY ICCD test hardware), I'm able to send commands to the card and I get back the expected responses.
In the JCOP Shell, I only need to select the applet (/select |<application name>) and after that send a command (send 8002000009, in my case read 9 bytes starting at location 0x00). In the Shell, I correctly get back the expected data.
When I disconnect the USB cable for communication between Shell and development hardware and put this hardware into a CardReader, the ATR is detected, just as seen in the Shell. But then, whatever commands I send, I get responses I can't explain. Below some example.
To be clear, I did nothing but running the applet in the IDE and after that disconnected the cable. Is there some special step/command needed between a run from the Eclipse environment and run "in the real world"??
Can anyone give me a clue for this??
First case, Send five zero bytes after ATR

Yes, I program the SmartMX using the USB connecter and the put the card hardware into a COMMON(!) card reader. This simply converts serial data from a PC serial port to data to the card. In our application, the controller that's communicating with the card has no 7816 interface, so we have to do that in software. To see what to do on the 7816 port, we use the PC serial port and the card reader hardware.
At this moment, it seems it has something to do with the software implementation of the 7816 protocol. The applet is not relevant, yet, because it's not even entered.
Thanx,
ErikTAh, OK. Your controller does not have the ISO7816 protocol implemented. So you have a lots of work in front of you. Check out ISO7816-4, T=1 .. I assume you have an error in the block structure (e.g. NAD, EDC ..).

Applet runs on local PC but not over network

My applet runs just fine locally within an html container file but when I post it to my website, (both html file and class file in the same folder ) the applet has errors.
Are there some classes that can't be used in downloaded files. Do I need to change some settings on Internet Explorer?
Does the class need to be downloaded ahead of time? I thought the class was downloaded and run upon html access?
Here's hoping for an easy answer. The website applet feature was one of my reasons for wanting to learn JAVA.

EBS Forms functional script runs fine in OpenScript but not from OTM

Hi,
I have an EBS forms functional test script which runs fine in OpenScript, but when scheduled from OTM, the web part runs fine but when it comes to forms, the script fails with the following error:
Forms Object Not Found! XPath: //forms:window[(@name='NAVIGATOR')], Type: oracle.oats.scripting.modules.formsFT.helper.test.FormWindow, Cause: No Matches <Less>
I have performed all the steps below already:
1) Stopping the OATS Agent service and changing it to manual.
2) Starting the command prompt and running the AgentManagerService command as mentioned in your forum.
3) The console displays

Hello Aarti!
I had the same problem and this steps help to solve the problem:
You need to enable Forms Automation under agent. Please follow by below steps.
1.open command prompt
2.cd C:\OracleATS\agent

Why are Java SASLFactories missing when called via PL/SQL but not from JRE?

Hi
This may be quite a technical point about SASL and JCE Providers etc OR it may just be a question about how Oracle PL/SQL interfaces with Java.
The background is that I am trying to get a Java opensource library to run in Oracle DB - this is for specialized communication from Database to other servers.
The library uses a SASL mechanism to authenticate with the server and this (appears) to rely on JCE Providers installed and provided by the JRE.
I have some Java code working which uses the library - this runs OK in NetBeans/Windows environment and also using Linux/Oracle JRE directly such as:
  +# $ORACLE_HOME/jdk/bin/java -classpath "./MyMain.jar:./OtherSupport.jar" package.TestClient+
However it refuses to work (throws a NullPointerException) when called from PL/SQL.
  +FUNCTION send_a_message (iHost IN VARCHAR2,+
     iPort IN NUMBER,
    +iLogin IN VARCHAR2,+
    +iPasswd IN VARCHAR2,+
     iRecipient IN VARCHAR2,
     iMessage IN VARCHAR2) RETURN NUMBER
   AS LANGUAGE JAVA
   NAME package.TestClient.sendATextMessage(java.lang.String, int, java.lang.String, java.lang.String, java.lang.String, java.lang.String) return int';
In the Java code this is:
   public static int sendATextMessage(String iHost,
     int iPort,
     String iLogin,
     String iPasswd
     String iRecipient,
     String iMessage)
I've tracked the issue down to there being no SaslClientFactories (via Sasl.getSaslClientFactories()) showing when called from PL/SQL whereas 3 are available when run from within Java directly. This via:
   Enumeration<SaslClientFactory> facts = Sasl.getSaslClientFactories();
   System.out.println("Found Sasl Factories [" & (facts != null) & "] size[" & Collections.list(facts).size() & "]");
So, is there some aspect of Java initialisation that I'm missing when calling from PL/SQL (which means SASL factories aren't getting loaded into JRE) or is there something different in SASL setup?
Any pointers appreciated.
Thanks
Dave

Ok, after a bit of reading and general hacking about I have got this working.
What I hadn't initially understood/remembered is that for a Stored Procedure the JVM installed on file system with Oracle isn't actually used - java code is loaded into the database and hence a different set of base functions are available. The following is a good explanation of this http://docs.oracle.com/cd/B14117_01/java.101/b12021/appover.htm#BGBIBDAJ
So "out of the box" the Oracle Database appears to come loaded with only two of the Sun security providers i.e. no com.sum.security.SASL
>
OBJECT_NAME             OBJECT_TYPE     STATUS   TIMESTAMP
com/sun/security/auth/NTSid  JAVA CLASS    VALID   2013-02-14:14:08:57
com/sun/security/jgss/GSSUtil    JAVA CLASS    VALID   2013-02-14:14:08:57
>
This is from:
>
SELECT
  object_name,
  object_type,
  status,
  timestamp
FROM
  user_objects
WHERE
  (object_name NOT LIKE 'SYS_%' AND
   object_name NOT LIKE 'CREATE$%' AND
   object_name NOT LIKE 'JAVA$%' AND
   object_name NOT LIKE 'LOADLOB%') AND
   object_type LIKE 'JAVA %' AND
   object_name LIKE 'com/sun/security%'
ORDER BY
  object_type,
  object_name;
>
My solution (which may well be a work-around) is the following:
1) Downloaded JDK Source and extracted "com.sun.security.sasl" java code to my project
2) Added following code to my Stored Procedure ()
>
Enumeration<SaslClientFactory> saslFacts = Sasl.getSaslClientFactories();
if (!saslFacts.hasMoreElements()) {
  System.out.println("Sasl Provider not pre-loaded");
  int added = Security.addProvider(new com.sun.security.sasl.Provider());
  if (added == -1) {
    System.out.println("Sasl Provider could not be loaded");
    System.exit(added);
  else {
    System.out.println("Sasl Provider added");
>
3) Built my JAR file with the sasl package embedded (note: could only find Java 6 code, so had to comment out some GSS lines - but wasn't intending to use these)
4) Loaded JAR to oracle via "loadjava".
5) Add permissions (only found this out after a couple of failed runs)
>
call dbms_java.grant_permission('XMPP', 'SYS:java.security.SecurityPermission', 'putProviderProperty.SunSASL', '' );
call dbms_java.grant_permission('XMPP', 'SYS:java.security.SecurityPermission', 'insertProvider.SunSASL', '' );
>
6) Run gives the following:
>
Sasl Provider not pre-loaded
Sasl Provider added
...etc...
>
It works!. I confess I'm not sure of the implications of this for multiple calls/performance and if it will need to be added for each stored procedure call - may post back.
For completeness I should point out that after my load the Security providers look like this:
>
OBJECT_NAME             OBJECT_TYPE     STATUS   TIMESTAMP
com/sun/security/auth/NTSid    JAVA CLASS    INVALID  2013-02-15:09:11:36
com/sun/security/jgss/GSSUtil    JAVA CLASS    INVALID  2013-02-15:09:11:37
com/sun/security/sasl/Provider    JAVA CLASS    VALID    2013-02-15:10:03:21
>
i.e. the original couple are "INVALID" !

App runs in Eclipse environment but not from jar file with no error message

When I upgraded my jre to 5.0 my app does not run. After fixing the properties problem I had a few days ago it is now at least compiling and running within Eclpse
However, when I export to a jar file it runs to a certain point and then just goes away with no error message!!! I've narrowed it down to the exact point where it dies but don't understand why it dies and especially gives me no errors whatsoever. It just goes away.
It is creating an instance of a new class when it dies.
Can someone please help me?

Ok, well it doesn't. Anyway, I'm still having the same problems. I can run my jar file to a certain point and then the application just stops. I know this because I've put come message boxes in the application to let me know where in the app the system is.
It always dies when it is instantiating the new class called HeidiFrame; done by:
HeidiFrame heidiFrame = null;
if I put code in between the above line and before the below line, this code will work fine
heidiFrame = new HeidiFrame();
but if I put code after the above line, nothing happens
As I said this all worked fine until I upgraded to Java 1.5
If you look at http://java.sun.com/javase/technologies/compatibility.jsp there are 23 compatibility issues with the new release. We're using xml stuff so that was my first problem and the code wouldn't even compiile. Once I added in libraries, the code compiled and ran beautifully.
However, when creating my jar file so I can deploy this application , I've discovered that the jar file will only run to a certain point, as I've stated previously. So, that's my problem. Not that I can't run it from the command prompt, which I can't, but it's a gui application. I've tried changing things in the classpath file and the manifest to no avail. Nothing changes. The application starts but when it goes to instantiate the HeidiFrame class, which is the class that actually builds the gui it dies and goes bye bye.

SharePoint 2013 - document libraries and newsfeeds are visible when viewed using Internet Explorer running on the server but not from any other machine

On a single Windows 2012 R2 server I have installed SQL 2012 and SharePoint 2013 SP1 with the latest update roll ups. When I remote desktop to the server using the farm and site collection admin account and open page http://server_name_here using
Internet Explorer, I'm able to see newsfeeds and document libraries.
If I connected to a separate Windows 7 machine as the farm and site collection admin account and open page http://server_name_here using Internet Explorer, I'm able to view the SharePoint pages except I cannot see any newsfeeds or document libraries.
There's just blank space where they should be. I have repeated this process on several other machines that are not the server and get the same result on every machine (I've tried other servers, desktops, adding the SharePoint site to the trusted sites list
in IE, even using firefox). I'm using the same account as I did when I logged onto the server directly. Any thoughts as to what's going on?
Thanks!

Thanks for the idea, Harsh. What am I looking for?
It is currently set to the default of http://server_name and http://server_name:port_number (the latter is for Central Admin).
When I have access to the server, I have always done so the same way, using http://server_name. This was true when I access it from the desktop of the server itself and when I tried to access it from other desktops and servers (the machines where I had the
issues with the libraries and feeds not showing up). Are there other values I should add?
I have not tried to add http://server_FQDN as we don't plan on using that to access it but if you think it will help I would be happy to add it.

I need to delete files from my iMac hard drive, but not from my other devices (that are sync. to iCloud). How do I do this?? My Mac is a 24-inch Mid 2007 running on Mountain Lion. Thanks for your help.

I have recently recieved messages indicating that my start up disc is almost full. Consequently I need to remove some files from my hard drive. I've backed up my hard drive onto a NAS system & onto an external harddrive. The problem now, is that whenever I try to delete a file, a message comes up saying that if I remove this file from my hard disc it will remove it from all my other devices that are syn. to it. How do I remove a file (movies) from my iMac but not from other devices.
Thanks for your help
Robert

You're right - this question has nothing to do with iSync!
You're best bet would be to buy yourself an external Firewire or USB 2.0 hard-disk. There's no way you'll get 150gb onto an 80gb drive - certainly not in an instantly accessible way.
Your new Mac would've had the Migration Assistant appear during the initial OS install. This allows you to connect your new and old Mac together via a Firewire cable and automatically transfer your important files from old Mac to new.
Once you've all the files off your old Mac, re-format it and re-install the OS that came with it. If you boot up the Mac from the OS install DVD, there is an option to re-format the HD and install the OS.

Well if there is a EFI block, then running a program in OS X isn't going to do a lick of good.
After all EFI was designed for Trusted Computing and Digital Rights Management, to act between the OS and hardware, can read drives, contact the Internet and everything.
Windows doesn't use EFI, will have UEFI in Windows 8 though.

They show up in the search box, but when I click on the results it just kicks me to ALL my music. I have imported thousands of songs/CD's before and this is a new one.

Something may have gone wrong with the index of the Music playlist. Making another change to the library such as downloading the current iTunes Free Single of the Week, or deleting one track from your library and reimporting it, should fix the problem.
If that doesn't work close iTunes and delete the hidden file sentinel from inside the main iTunes folder, then start iTunes again. It should run a consistency check when it starts up which ought to correct things.

Want to delete mails from Thunderbird but not from the server?

Hi,
Please tell me how to configure the settings of Thunderbird so that if i delete any mail from Thunderbird that mail would be delete only from Thunderbird not from server. I'm using IMAP configuration for all my mail accounts and I'm using Thunderbird in my laptop and tablet both.
Currently i'm using Thunderbird 24.4.0 and i just want to delete my useless mails from Thunderbird but not from the server without using pop-3 settings.
Actually the reason for this Question arises because whenever i use to uninstall and reinstatement Thunderbird, i use to take "profiles" as a back up and its size is increasing day by day that is making a big issue to me as i cant take a back up of such a big size file.

Imap mail accounts keep the emails on the server and you see a remote view of those emails and folders.
When you subscribe to see a folder, the headers are downloaded, when you select an email to read, the entire folder is downloaded to a temp cache facilitating quicker access. If you synchronize folders, then a copy of that folder is downloaded to an mbox file in your profile, so that you have a copy of the server folder. When you make any changes to a synchronized folder, read an email, delete or move etc, then Thunderbird will resynchronize with the server to update the server. A synchronized folder allows you to work in 'offline' mode and this is the best time to perform a backup as you know there is a temporary stop on synchronizing as you are offline. They will resynchronize when you go back into 'online' mode.
So, with IMAP mail accounts, the folders you see in Thunderbird are the same folders on the webmail server. If you make any changes via Thunderbird or webmail then you are changing the same folder. You cannot delete an email without deleting it from the server, they are one and the same.
What you can do is move/copy an email into Local Folders and delete the one on the server. The Local Folders emails are kept in your Profile on your computer, these folders/emails are not on the server, unless you chose to keep a copy of them on the server.
Pop mail accounts cannot see the folders on the server. They only access the server Inbox folder and download emails not previously downloaded to the mail account Inbox in Thunderbird. These emails are kept on your computer in your profile folder. You can select to keep a copy on the server or not. You can choose to delete emails off your computer and off the server or not.
If the mail account is gmail , have you subscribed or even synchronized to see the 'All Mail' folder ? Gmail's all Mail folder is their Archive folder, it keeps a copy of all of your non-deleted emails. So, you do not need to subscribe to see this folder as it only shows you what you can already see in other folders. It doubles the disc space.
Please read section on 'All Mail' at this link.
* http://kb.mozillazine.org/Using_Gmail_with_Thunderbird_and_Mozilla_Suite
You do not have to download/synchronize the entire folder. You could select to only synchronize the most recent xx days of emails.

Welcome to the Apple Community.
Your best method would be to connect via USB and transfer that way, since videos are not transferred using photostream.
However you can stop photos on your mac being added to photostream in the iPhoto preferences > photostream by unchecking the automatic upload box.
