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 access class in jar file.
please helpYou have to either refer to the class in its fully quallified name, or import it into the JSP:
<%
some.full.packagename.RowSetDynaClass resultSet = new some.full.packagename.RowSetDynaClass(rs,false);
...-or-
<%@ page import="some.full.packagename.RowSetDynaClass" %>

...As long as the class has public visibility and you have re-started the server/servlet context since you added the JAR. -

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 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.YeWhen 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 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 self-defined class in a jsp page
Hello:
I defined a class for displaying purpose, which is in the different folder(WEB-INF/classes) from my JSP page.
In my JSP page, I want to create an instance of my class and display something, while I get the following error: "
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 12 in the jsp file: /htmls/templateIntro.jsp
Generated servlet error:

symbol : class Display
location: class org.apache.jsp.templateIntro_jsp
Display display=new Display(out);"
How can I solve this problem? Should I redefine my classpath or there are some other actions I should take.
T.I.A.
Oriental SpiritHere is what I have done:
1) in Display.java, add one line "package tools;" on the top, and compile it to
create Display.class.
2) create a new folder at
/home/jiao/jsp_webserver/tomcat/webapps/syllabus/WEB-INF/classes
named tools and then put the Display.class into the newly created folder.
3) in my jsp page, add " import="tools.*"
But it still doesn't work.
Any ideas? T.I.A. -
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 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,
-PramodhYou 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 two activex class objects in same vi

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

Did you try the database block on its own, just to confirm that it is working?
