How to use object of class in Label?

I have defined a class "time" which runs time for 30 minutes.Now, I want to use this time in Label so that it keep running for 30mins but I am not able to pass the object in Label.

Of course being aware that this may cause other
difficulties if you are running a multi-threadedapp.
SwingUtilities.invokeLater() may be required inthat
case.I've never really been clear on which of these update
routines should, or should not be on the dispatcher
thread. A quick look at the source of JLabel.setText,
for example, shows that it calls repaint on itself to
change the presentation of text, and repaint
shouldn't require to be on the dispatcher thread,
since it simply adds the paint request to the TODO
list.That makes sense, but experience doesn't bear it out... I've had deadlocks where the only thing being updated was the text of a label. Perhaps there is something else going on.

How to use RMI Stub class in programming?

Hi all,
I'm new on RMI.
Is there anyone can explain to me how to use RMI Stub class which is generated by invoking rmic command?
For my testing, I can only invoke rmi object nethod via its remote interface. Then what is stub used for when we are coding?
I do appreciate anyone's help.
Thanks very much,
Xianyi.Ye

When the remote object binds itself to the registry, what is actually bound is the stub.
So when the client does a registry lookup, what it gets is the stub. However from the client's point of view it is just some mystery object that implements the remote interface.
So you never have to use it directly, it is all automatic.

How to use the implementation class in propetty pallete

Hi,
I am using forms 10g....I have to insert horizontal scroll bar in text item..
I have only class files instead of jar files ...how cani place the class file instead of jar file...
How to use the implementation class in property palette to display the PJC
Thanks,
Ansaf.

The Implementation Class must reflect the full name of the class. For instance, if the full class name is : xx.yyy.zz.class_name, then put this in the Implementation Class property of the corresponding item.
Also, the class must be stored in the equivalent directory structure, so that, in my example: <DEV_HOME>/forms/java/xx/yyy/zz

How to use Object Class:orclDbServer in OID

Not sure if i have posted in the correct forum, I am quite new to OID
I am planning to use orclDbServer Object Class, but not sure how to use, i have searched in Google, and Oracle Documentation, there are so little information about this, there are only:
Object Class: orclDbServer
Description: Defines the attributes for database service entries
Attributes: orclNetDescName, orclVersion
Below is the ldif file i created for add one entry with object class orclDBServer:
dn: cn=orclDBServer_test, cn=OracleContext, dc=ldapcdc, dc=lcom
changetype: add
objectclass: top
objectclass: orclDBServer
cn: orclDBServer_test
orclNetDescName: (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST=10.182.114.121)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = oh112)))
after i use below command to add this entry:
ldapadd -h localhost -p 389 -D "cn=orcladmin" -w welcome1 -f test_add.ldif
then use ldapsearch to search:
ldapsearch -h localhost -p 389 -b "dc=lcom" "objectclass=orclDBServer"
the result is like below:
cn=orclDBServer_test, cn=OracleContext, dc=ldapcdc, dc=lcom
cn=orclDBServer_test
orclnetdescname=(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST=10.182.114.121)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = oh112)))
objectclass=top
objectclass=orclDBServer
objectclass=orclService
It seems it added a line for me:
objectclass=orclService
Is there anything wrong with my ldif file when i want to use orclDbServer?

Hi,
if you are having main controller and sub-controller then you may need to use below coding to use application class reference.
*Data declaration
DATA: obj_cntrl        TYPE REF TO cl_bsp_controller2,
         obj_sub_cntrl   TYPE REF TO z_cl_sub_cntl,
         application TYPE REF TO z_cl_application.
*Get the controller
CALL METHOD obj_main_cntrl->get_controller   "obj_main_cntrl is the object of main controller
    EXPORTING
      controller_id       = 'SUB'   "Controller ID
    RECEIVING
      controller_instance = obj_cntrl .
obj_sub_cntrl ?= obj_cntrl .
application ?= obj_sub_cntrl ->application.
or simply use below code in your controller method.
application ?= me->application.
Thnaks,

How to use two activex class objects in same vi

HI
I am using labview to read ECU data from INCA software .INCA providing COMTOOL API(incacom.dll). I am using ACTIVEX for communication between INCA & Labview. My problem is If I have used single activex class object I am able to read Inca version, getting the database path etc. If I have used two activex class in same vi (one to open Inca & other one is to read the folder structure) I am not getting output.I have attached snapshot for referance

It wasnt in the first two images you posted, or I couldnt see it anyway! That was the only reason.
Did you try the database block on its own, just to confirm that it is working?

How to use Landmark & LandmarkStore classes in Location API

hi
i have some problem to use Landmark & landmarkStore classes in location api . any one give source link to use these calsses.

1) why not simply create two different timer objects, one for one image, the other for the other. I would caution you that you may wish to limit the area of your repaint so as not to slow down your app repainting everything when you only need to repaint the area around your sprites.
[http://www.java-forums.org/awt-swing/14590-how-use-multiple-timer-classes-swings.html]
2) Please note that cross-posting can frustrate anyone who tries to help you only to find out later that the same answer was given hours ago in a cross-posted thread. No one likes wasting their time, especially a volunteer. The polite thing to do would be to not do this, but if you feel that you absolutely must, to at least provide links in both cross-posts to each other.

How to use PKCS related classes?

Hi,
I am happening to deal with PKCS7. The client will send me (the server) a PKCS7 envelope and I need to decrypt and/or get data like certificate, etc from the PKCS7 envelope. Are the required/related classes not part of Java API? We use 1.4.2_06. Do I have to use/buy/download any special API to deal with pkcs?
This link http://java.sun.com/products/jce/jce122_providers.html says one needs to buy one of the listed Cryptographic Service Providers. Did any one deal with PKCS? If so what did you use/buy/download? Is there any information on net on how to use those APIs - examples, samplex, documentation, etc?
Thanks in advance for help,
-Pramodh

You can use the BouncyCastle JCE provider to use PKCS7 objects. It is free. David Hook's book "Cryptography in Java" provides numerous examples of how to use the BC libraries with PKCS objects.

How to use the Rectangle class to draw an image and center it in a JPanel

I sent an earlier post on how to center an image in a JPanel using the Rectangle class. I was asked to send an executable code which will show the malfunction. The code below is an executable code and a small part of a very big project. To simplifiy things, it is just a JFrame and a JPanel with an open dialog. Once executed the JFrame and the FileDialog will open. You can then navigate to a .gif or a .jpg picture and open it. What I want is for the picture to be centered in the middle of the JPanel and not the upper left corner. It is also important to stress that, I am usinig the Rectangle class to draw the Image. The region of interest is where the rectangle is created. In the constructor of the CenterRect class, I initialize the Rectangle class. Then I use paintComponent in the CenterRect class to draw the Image. The other classes are just support classes. The MyImage class is an extended image class which also has a draw() method. Any assistance in getting the Rectangle to show at the center of the JPanel without affecting the size and shape of the image will be greatly appreciated.
I have divided the code into three parts. They are all supposed to be on one file in order to execute.

How to use objects as a message type in WSDL?

How can I use object as a type for the message in WSDL?
For example, I want to achieve something like this:
<message name="DBConnection">
<part name="conn" type="???"/>
</message>
In the above example, for any operation getConnection(), the return type would be an object of the type Connection.
Any suggestions ?

Hi,
Listed below is the step by step intructions to configure the Nokia device as a modem to a mac.
Steps:
Connecting your Mac to the internet is convenient and easy with your a compatible Nokia S60 device. You'll need a Nokia S60 device that supports a 2G or 3G data connection (such as GPRS or HSDPA), a compatible Mac (with the latest OS X), a USB cable for your Nokia device or a Bluetooth-enabled Mac, and a network subscription with your mobile service provider.
To set up your device you'll need to know your operator's Access Point Name (APN) and have the packet data service enabled. For help with this please contact your operator.
In Settings select and open Connection >Select and open Packet data > Select and open Access point >Type in your operator's Access Point Name
Exit Settings. Your device is now ready to be used as a modem for your Mac!
Bluetooth Connection: Pairing between Mac and Device using bluetooth, follow the instruction from here: http://europe.nokia.com/get-support-and-software/download-software/device-as-a-modem/connect-to-your...
Note: Preferred mode is USB as it much faster than Bluetooth.
Connect the device and then go to System preferences- >Network- >Select Device (Nokia XXX)
Click on Advanced Tab > Modem tab
- Vendor : Nokia
-Model:GPRS (GSM/3G)
-Telephone Number: *99***1# (contact your operator to get this settings)
-APN: airtelgprs.com (contact your operator to get this settings)
CID: 1
Once connected it will be highlighted in green.
Hopefully this helps.
Cheers

How to use JAXB generated classes with SOAP

hello,
I have a library of JAXB generated classes for my web service. There is a Java class for each web method defined in my schema. For example, my getLocation method is mapped to GetLocation.class.
However my web service is SOAP based, so I am having to manually strip off the SOAP elements to be able to unmarshall the getLocation xml to a GetLocation class.
I am noticing a disconnect between JAXB and other Java SOAP and RPC libraries. Does anyone know how to create a JAXB class for SOAP Envelopes and Bodys? Does anyone have any ideas how to incorporate the existing Java web service libraries with JAXB?
Thanks in advance.

Have you found a method to integrate SAAJ and JAXB? Or
is better to use SAAJ only ?If I had to choose I'd go with SAAJ. It seems to me that's theoretically possible to use JAXB classes with SAAJ but I imagine if it is possible it would be a big pain in the ass.

How to use the message class CL_BSP_MESSAGES in the event handler?

How to use Object Model

Hi,
We are evaluating the Adobe Captivate software and we are in
the process of identifying on how to use the Object model to record
the screen Programmatically. Do you have any idea on how to do this
using the captivate object model? We have a custom application and
we want to activate the recording by clicking a button in our page.
Kindly help. Thanks.
Eric

Hi Captiv8r / Rick,
Thanks for your answer,
Actually, we have a web application that utilize the WME
(Windows Media Encoder) to record a video from the client side by
just clicking a button on our web page. That button has the
application logic to start the recording of his screen via calling
some "methods" on the WME dll files via object model (API). Now, we
are looking for some possible solutions on how we can implement the
same thing using the Adobe Captivate software or how we can utilize
adobe captivate to be able to integrate this software within our
web application.
Do you have any suggestions on how we can leverage the
benefits of adobe captivate in a custom web application? Thanks.
