How to use Java code to implement Divide-and-Conquer multiplication???

i think use Divide-and-Conquer multiplication algorithm to multiply 31415975 by 81882818. Because i have study data structure and algorithm for needs people helps to solve this problem!!! The answer is should equals the both number (31415975 * 81882818) multiplication! There are must pass the program to calculation the multiply with use divide-and-Conquer!
How to use the program calculation the both number multiplication with divide-and-Conquer??? That is needs display the different number multiplication on the screen!!!

This is what I think you meant to say

The result should equal the product (multiplication) of the two numbers (31415975 * 81882818)
The input must be passed as parameters to the program to calculate the product using Divide-and-Conquer!

How to use Java code inside WebDynpro-ABAP

Hi,
How to use Java code inside WebDynpro-ABAP.
Could any one provide sample code.
Cheers,
Sam

Hi Sam,
We can't Bring Java Inside the ABAP. Both are running in different Environments.
and also ABAP Codes are runs on BASIS.
-Basis is a middleware between ABAP codes and Ur OS.
-Contains set of programs to load,RUN,intepret the ABAP program..
So Both are Different.

How to use Java code signing certificate in oracle 11i

Hello,
I am try to configure java code signing certificate in 11.5.10.2 application. we got java sign certificate from verisgin. SA's imported the certificate and created alias XXX_XXX with password and passphrase.
I am able to see the my certificate. keytool -list -v -keystore xxx_xxxx.jks -storepass Password.
how do I use it. I am using Enhance Jar Signing for EBS DOC ID 1591073.1.
could you please give me some advice on it?

You cannot use java directly inside forms. You can either create a java-bean to enhance the GUI (as you have some UI-components in your java-code, i guess this would be the direction) or use the java-importer and call server-side-java. Both require that you are running forms in a web-version and not as client-server.
What exactly is your requirement?

How to use Java NIO to implement disk cache for serialized java objects

Hi,
I have a cache (implemented as hahstable etc.) that contains java objects (mostly strings) and swaps objects from runtime memory to the disk and back based on some algorithms. Currently, the reading and writing from the disk is implemented using java.io.* package i.e. fileInputstream and FileOutputStream. Essentially, I serialize the java object and write to the disk and the deserialize and give it back to the Hashtable cache.
The performance of swapping from disk to memory is kinda slow. I have read that memory mapping would improve the performance.
My idea is to do the following:
Have one big file mapped to memory. I write the serialized objects to different portions of the file and then read those portions when needed. I can use the MappedByteBuffer for that but then I have the following questions. I will not store objects in the hashtable anymore.
1. How do I delete things from the cache in the above design i.e. how do I delete portions of a mapped file?
2. How do I serialize objects using ByteBuffers and then deserialize them? I guess this shouldn't be hard but just want to confirm.
Do you think this is the right design or should I change? Right now using the old io package, I have a separate file for each object. When using the NIO package, I want to store all objects in a single file in different portions of the file, is that the right way to go?
As you can see, I am beginner in memory mapped io and need help.

Have one big file mapped to memory. I write the serialized objects to different portions of the file and then read those portions when needed. I can use the MappedByteBufferThis is a good idea, one that I have worked on. It involves quite a bit of manipulation with temporary buffers and a deep working knowledge of object serialization.
1. How do I delete things from the cache in the above design i.e. how do I delete portions of a mapped file?The best way to handle this is do a two-step process, cutting the file into two pieces and gluing it back together where the original one is...
2. How do I serialize objects using ByteBuffers and then deserialize them? I guess this shouldn't be hard but just want to confirm.It is hard. Wrapping the streams and making the IO work properly is not the challenge however. The hard part comes in hacking the object streams. The object input/output streams use a ClassDescriptor object which only gets written once/ read once. This shouldn't be a problem if you will read/write the entire file at once, but will bring you grief if you want random access to your objects. You will also need an indexing mechanism to support random access.
Do you think this is the right design or should I change? Right now using the old io package, I have a separate file for each object. When using the NIO package, I want to store all objects in a single file in different portions of the file, is that the right way to go?I guess it depends on your needs. Do you require random access to objects? NIO provides some performance gains, but mostly for very large amounts of data (>10M in my experience).
You can always write all your objects into the same file using normal io techniques and you can still generate an index and acheive random access. It might be easier...
Good luck

How to use Java Robot to click the same button multiple times

Hi All,
I am trying to use Java Robot to turn a Windows utility located on the Desktop by clicking the same button on and then off with the following code:
1. Robot robot1 = new Robot();
2. robot1.mouseMove(400,180);
    // Turn on the utility
3. robot1.delay(100);
4. robot1.mousePress(InputEvent.BUTTON1_MASK);
5. robot1.delay(100);
6. robot1.mouseRelease(InputEvent.BUTTON1_MASK);
    //Wait for 2 minutes
7. robot1.delay(200);
    // Move the mouse to disconnect button
8. robot1.mouseMove(400,180);
    // Turn off the utility
9. robot1.mousePress(InputEvent.BUTTON1_MASK);
10. robot.delay(100);
11. robot.mouseRelease(InputEvent.BUTTON1_MASK);However, only the first click (line 1 - 7) worked. Everything from step 8 onwards doesn't appear to be doing anything. Even instantiating another robot2 to carry out step 8 - 11 did not work either. Also have tried running steps 9 - 11 only. ie skip 8.
My aim is to turn this tool on and off at regular interval.
Any assistance would be greatly appreciated.
Thanks in advance,
Jack

Hi darth_code_r and Vincent,
Both you and Vincent are right about insufficient time between the release ( 6 ) of mouse button and step ( 9 ) press the same button again to turn it off. You are also correct in saying that it was not necessary to move the mouse again ( 8 ) since it was sitting on the right button already.
Below is the code I have ended up with which worked for me:
1. Robot robot1 = new Robot();
2. robot1.mouseMove(390,150);
4. robot1.mousePress(InputEvent.BUTTON1_MASK);
6. robot1.mouseRelease(InputEvent.BUTTON1_MASK);
     //Wait for 3 minutes
7. robot1.delay(30000);
9. robot1.mousePress(InputEvent.BUTTON1_MASK);
11. robot1.mouseRelease(InputEvent.BUTTON1_MASK);This utility also takes a few seconds to turn itself on and vice versa. As a result, it is necessary to give it sufficient time to turn on prior to turning it off again with the second mouse press.
Thanks to both of you very much,
Jack

How to use java connecter to access Mainframe and ERP applications from EJB?

yea. its just a desktop chess application.
my IP changes and im behind a router so its hard to
get
connections to my computer. i figured i could have a
central
server to manage the connections online.
and later maybe having other applications running on
the website that people can connect to.Well now I am more confused...
Here are the options.
1) If you want to run your service program on a server you're going to need some sort of virtual server hosting package. When people say Java hosting they usually mean Servlet/JSP hosting in a Servlet/JSP engine/container.
But this does not appear to be what you need. You appear to need to be able to just run whatever you want. There are virtual server hosting packages out there for fairly cheap... although as always a caveat in that you tend to get what you pay for.
2) You could just have a website with a servlet (not neccessarily Java could be ASp or PHP or whatever you like) acting as a webservice. You could send your IP of your server to the service. Then clients requesting a connection would get the current IP from your webservice.
3) You could do like (2) but without the webserver, use DNS instead. There are some services for providing DNS for dynamic IP's about.
It should be noted that if you want to do applets then probably based on your description you will need to sign them. Generally speaking applets can only connect to the server from where they were downloaded from.

How to get the values from struct data type using java code..?

Hi ,
I am newer to java.
we are using oracle database.
How to get the data from struct data type using java code.
Thanks in Advance.
Regards,
kumar

Hi Rajeev,
To retrieve a FilterContainer you will need to traverse the report structure:
ReportStructure boReportStructure = boDocumentInstance.getStructure();
ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
FilterContainer boFilterContainer = null;
if (boReportContainer.hasFilter()) {
boFilterContainer = boReportContainer.getFilter();
} else {
boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
Hope this helps.

Dan

How to dynamically configure JPA setting at runtime using java code?

Hi,
I am new to EJB 3.0 and JPA. I am trying to help my company to deploy the use of JPA in EJB3.0. Currently, i am trying out with OpenJPA in IBM Webshpere Application Server 7.0. We have four different WAS servers running for testing, system integration testing, user testing and production respectively, and in each region, the configurations for data source, JDBC username and password, schema, etc are different. So i think i would need to configure the JPA setting during runtime using Java code that determines which is the environment. And apparently i am stuck with the limited knowledge i have.
1) I understand that i could override the JDBC in the persistence xml by creating entity manager using entity manager factory. But is it possible that i do similar thing by using inejction of persistence context on entity manager to obtain a container managed entity manager?
2) Alternatively, it is possible to create multiple persistence unit in the XML and inject different PU to the entity manager, am i right? But how to inject dynamically since @PersistenceContext(unitName="xxx") only accepts constant declaration.
3) Is it possible that the JDBC username and password are read from properties file?
Thanks for your help in advance!

Hi
Thanks for the reply.
Are you saying that i have to configure the data source authentication to the backend DB2 using the JAAS-J2C? Correct me if i am mistaken. I guess i am unable to do so as the application server setup only contains one data source, and the server hosted a number of applications. Every applications has their own JDBC username and password supply to the data source (the ID supplied at the DB2 side will decide which resource can access) and thus, i have to supply the username and password at runtime. Talked to the server guy and seems that it is not feasible to have seperate datasource for each applications as considered to the volume of applications hosted inside the server.
Any suggestion?

You have several ways under *nix
ifconfig -a | grep HWwill output something like
eth0 Lien encap:Ethernet HWaddr 00:11:FF:74:FF:B4combined with Runtime.getRuntime().exec("")and Process.getInputStream()you should be able to read it easilly.
Under Windows (and Linux of course) try jpcap (http://sourceforge.net/projects/jpcap)
You can also use jnative as a generic tool (http://sourceforge.net/projects/jnative)
