Using BIG Integer in java

I am trying to get the first byte from the Big integer and set
the bits(0-127) on that byte, Can someone throw some ideas how can i do this.
How should i define my bit array?

Use testBit, setBit, and clearBit. Maybe you can also use toByteArray.

Can I Design a Forum with using web dynpro for java?

Hi All:
Can i design a forum with using web dynpro for java?
I want to design an application like a simple forum which maybe has many replies.So if i use
the UI technology "web dynpro for java", i will to create UI elements dynamically.How can i control this
dynamical UI elements to keep layout ?

Hi,
yes you can do that....
for exaple if you observe SDN...
you can imagine like....
A big Transparent Container(TC)....
Inside that number of other TCs(depending upon the question nd its replies...)....
In side each TC, again around 9 UIElements....
one for menioning what is the question/reply?
other for your description of question/reply...
other for your name,
displaing your fourm point... etc...
So it will be
for(loop till your (Question+No of replies))
Create Transparent Container....
Add Childs to the Container...
Decide your layout....
In case if you want to know how to create UIElements dynamically....

What is big integer?

Hi,
I have set db_4k_cache_size.
SQL> alter system set db_4k_cache_size=4k scope=spfile;
System altered.
After shutdown and startup, I see the value as follows,
db_4k_cache_size big integer 4194304
What is this? 4194304 = 4k*1024, why set Oracle the value*1024?

SQL> alter system set db_4k_cache_size=4k
scope=spfile;
After shutdown and startup, I see the value as
follows,
db_4k_cache_size big integer
4194304First of all, it must be clear what you are configuring with the db_4k_cache_size. This is a special cache you setup to allow your database to manage different sizes of datablocks. Here you are willing to manage a 4K blocksize Tablespace along with your default block sized tablespaces. A db_block_size different from 4K is assumed.
Next, you are declaring an space of 4K ?! Too short for a database buffer cache. What's the use of reserving a 4K block sized cache to store just one single 4K block?
So a more suitable value must be defined. Let's think about 8M, you could store up to 2,048 4K blocks; a much more reasonable value than 1.

We encountered a problem during use the Configtool access JAVA engine.

We encountered a problem during use the Configtool access JAVA engine.
Our environment of system as below:
HardWard: IBM i570
OS: IBM as/400 V5E3
DB: DB2/400
Application system:SAP XI 3.0
The problem we encountered as below:
Our company used XI 3.0 SR1 for exchange data between SAP R/3 and no-sap system.For now,we wanna create a backup system(for
offline recovery),so we backup the XI product system throught entiry system save in AS/400(we stopped the XI system before
save process start).And following,we restored from the tape that we save from XI product system to the new backup system(they
are whole different paratition),but the problem is coming.Describe as following item:
1. The application seem to can be started but the java node always restart circularly(We have 4 java node now),I think
because of different of hardware configure(between XI product and Backup system) and lack of hardware resource.(XI prduction
have 5 CPUs and 22G Mem,Backup system have 2 CPUs and 16G MEM ).Therefore we wanna decrease the number of java nodes for
start application in backup system(throught configtool).
2. We wanna use configtool to decrease the java nodes for start backup system.But we encountered a problem during running the
configtool ,the information of prompt dialog as following:
Error occurred while working with Configuration (Scanning).
Msg:Error while connecting to DB.
We also see the system.log that below the directory of usr\sap\PXI\DVEBMGS00\j2ee\configtool,and found some error as

Unable to Print Purchase order automatically using SAP GUI for JAVA

Hi SAP gurus,
Some of the PC's in our company use windows and some LINUX. Therefore we use two types of SAP GUI. One for windows and the other one JAVA. PO approval was set to print automatically. In a windows setting, there are no problems with this setup. But in SAP GUI for JAVA, no print outs are produced and no error messages are displayed. I am using SAP GUI for JAVA version 7.10 ver 6. and I use Front end printing for linux access method G.
please help,

hi gungertz,
You can use U type access method for printing SAP document using linux desktop.
Please refer to my blog posting here (http://sapbasis.wordpress.com/2007/08/23/print-sap-documents-using-linux/)

if my longMessage is smaller like one line then everything works fine, but as soon as my longMessage if greater than 254 it starts giving me -404. How do I work around or Is there any way to use host variable in Java?
All kind of help is appreciated. Any question then please email me at [email protected].
Thank you.

This is what you got to do to insert a larger value.
//Assuming that message length is less than 254+ 254 characters.
//If larger then run the update loop that many times.
String longMessage = "Blah blah ... ";
String firstPart = "";
String secondPart = "";
int messageLength = longMessage.length();
if (messageLength > 254)
     try
          firstPart = longMessage.subString(0, 253);
          secondPart = longMessage.subString(254, message);
     catch (IndexOutOfBoundsException e)
//In the first insert set the first 254 characters
ps.setString(1, firstPart);
int result = ps.executeUpdate();
if (result != 0)
       System.out.println("Insert sucessful ");
       if (messageLength > 254)
            //now update with the second part.
            static String UPDATE_SECOND_PART = UPDATE my.table SET LONG_COL = LONG_COL || ? WHERE KEY_COL = ?;
            ps2 = connection.getPreparedStatement(UPDATE_SECOND_PART);
            ps2.setString(1, secondPart);
            ps2.setString(2, businessId); //assuming that businessId is the primary key.
            int result2 = ps2.executeUpdate();
            if (result2 != 0)
                  System.out.println("Update sucessful ");
            else
                 System.out.println("Update failed ");
else
       System.out.println("Insert failed ");
}Hope this helps.

My answer to that would be, search the Internet for a JDBC driver.

How to use Thread.sleep() with Java Berkeley Base API?

Hi,
I have explained the weird problem about the server was too busy to response to SSH but it continued to finish to run (Server not response when inserting millions of records using Java Base API
Even I tried to increase CachSize and renice Java program, but it did not work. So, I am thinking to set sleeping time for threads in Java Berkeley Base API (using “ps” command, there were 18 light weight processes created). My program did not implement transaction or concurrency because it simply creates (millions) databases records only. Is it possible and correct to do like this in the code:
try{
//do create a db record
Thread.currentThread().sleep(1000);//sleep for 1000 ms
catch(ItrerruptedException ie){

where can I get the help doc about use AT commands in java.
Can you give me some code example about this. It is
difficulty to me to write it myself.You simply have to send the characters and receive the characters via the comm extension. Here is the ITU standard command set - http://ridge.trideja.com/wireless/atcommands/v250.pdf. Various modems and other devices extend this in a number of ways, you may need to find documentation specific to your device as well. But start with the standard.

Parsing an XML using DOM parser in Java in Recursive fashion

I need to parse an XML using DOM parser in Java. New tags can be added to the XML in future. Code should be written in such a way that even with new tags added there should not be any code change. I felt that parsing the XML recursively can solve this problem. Can any one please share sample Java code that parses XML recursively. Thanks in Advance.

Actually, if you are planning to use DOM then you will be doing that task after you parse the data. But anyway, have you read any tutorials or books about how to process XML in Java? If not, my suggestion would be to start by doing that. You cannot learn that by fishing on forums. Try this one for example:
