resultset

create emp named table 
                        System.out.println("EId        
Ename            DOB                        Dept       
Salary\n");

			}
			stmt.close();
			conn.close();
		}

		catch(Exception e)
		{
			e.printStackTrace();
		}
	}
}

Note:
-create emp table 1st wid attributes eid,ename,dob,dept,n   
 salary
-to add dsn(data source name)go to control   
 panel->Administrative Tools->Data Sources (ODBC) then one 
 small window will get opend..
-click on System DSN tab->Add->n select "Microsoft Access
Drive(*.mdb)"->finish->type Data Source Name(as i hv typed
in program "employeedsn" if u dnt want to change that dsn
which is written in d line
conn=DriverManager.getConnection("jdbc:odbc:employeedsn")

-you can give ne name tht u want instead of employeedsn...u
only need to provide d same name in Data Source Name

-next is no need to provide nethng for description
-then click on->select(to select database in *.mdb form)
   ---to select database table select drive on which u hv
saved ur database table n select that table by going to d
folder where u hv stored it by going to an appropriate directory
   ----if u select correct directory,table name will b
displyed in left hand side list box which then u need to
select n click on "OK" n again click on "OK"
    ----Your DSN will be displyed in System Data Sources List
---click on Ok n once you done this run the program

put it in a session as an attribute.

I think it is not possible.

please post the answer...



thanks and regards

Join:It is the combining of two rows from different tables 
based on the comparative values in selected columns.

Types of Join : Cross Join, Inner Join or equi join and 
Outer Join which comprises of Left join and Right join.

Inner Join : It is used to select certain fields from both 
tables and only correct rows will be joined together.
Sytax:SELECT <column_name> FROM <Table1>, <Table2> WHERE 
(Table1.column = Table2.column)

Outer Join:
  Left join: It returns all the data's from the table 
present in left of the join and only those data's from the 
right tabel which matches the condition.
  Syntax:SELECT <column_name> FROM <Table1> LEFT JOIN 
<Table2> ON Table1.column = Table2.column (Conditions like 
WHERE and USING)

  Right join: It returns all the data's from the table 
present in right of the join and only those data's from the 
left tabel which matches the condition.
  Syntax:SELECT <column_name> FROM <Table1> LEFT JOIN 
<Table2> ON Table1.column = Table2.column (Conditions like 
WHERE and USING)

/* How to convert string containing decimal point into integer
in java? For example given a string like "3.14" as input how
to get integer 3 as result. */

String myStr = "3.14";
Int myInt = Float.valueOf(myStr).intvalue();

class StringToInt {
	public static void main (String[] args) {
    String s="3.14";
    double i=Double.parseDouble(s);
    int i1=(int)i;
    System.out.println (i1);
 
    }
}

I don't know

/***************************************************/

import java.io.*;

class StringToInt 
{
	public static void main(String a[]) throws 
IOException
	{
		String s;
		BufferedReader br = new BufferedReader(new 
InputStreamReader(System.in));
		do{
			s=br.readLine();
			System.out.println("U R Sting 
is: "+s);
		   }while(s.equals(" "));
		try
		{
		  double d = new Double(s);
		  int j = (int)d;
		  System.out.println(j);
		}catch(NumberFormatException e)
		{
			System.out.println(" Your String is 
Not a Number:..  ");
		}
	}
}

For the above given question 3 is answer while converting
decimal to integer

String str = "5.22";
Int result = Float.valueOf(mystr).intValue();
// value of result is 5

You have to use javscript or use some database connectivity 
in JSP program.

We should use Date object from java or JavaScript.

Calendar c=Calendar.getInstance();

c.roll(Calendar.MONTH, 1); 
Date d4 = c.getTime();
System.out.println("new date " + d4.toString() );

Common Examples
----------------
Let's say I have a Java application consisting of three 
source files that I wish to distribute:

One.javaTwo.javaThree.java

I also want to call my JAR file example.jar. To make a JAR 
file with just One.java:

   jar CF example.jar One.java
To make a file with all three files listed separately:

   jar CF example.jar One.java Two.java Three.java
To make a file with all three files using a pattern match:

   jar CF example.jar *.java

It goes (almost) without saying that the source files are 
in the same directory you are running the jar command in.



 

------------------------------------------------------------
-----------------

Compress Files To An Executable Java Archive (JAR)
---------------------------------------------------
It is also possible to make an archive that can be executed 
(run) by Java and even by a double click through your OS, 
if you have it set up correctly. Of course, to do this you 
must store compiled class files in the archive, as well as 
or instead of Java source files, since Java source files 
cannot be run! 

Continuing the example above, I now compile my Java source 
files:

   javac *Java
or

   javac One.java Two.java Three.java


 

------------------------------------------------------------
--------------------

Create An Executable JAR
---------------------------
All JAR files contain something called a manifest file 
which holds information Java wants to know. One piece of 
information a manifest file may contain is the name of a 
class that will be run if the JAR file is executed.

The first thing you must do is create a text file that 
lists the "main" class - the class that has the main method 
you want executed when the JAR is executed. Let's say that 
Three from the above example has the main method I want 
executed. I create a text file called "mainClass.txt" with 
the following text:

Main-Class: Three
 
IMPORTANT: the text file only needs the one line of text 
for this purpose. However, the file must end with a blank 
line or this will not work, ie the file has two lines in 
it - the second one is empty. Note too the class is 
called "Three" and not "Three.java" (the file containing 
the source code) or "Three.class" (the file containing the 
byte codes). If your class file is in a package hierarchy, 
you must use the fully qualified name of the class 
(eg "myPackage.MyClass").

I then run the jar utility with this command line: 

   jar cmf mainClass.txt example.jar *.class
With this line, I told jar to create a JAR file (option c) 
with modifications to the manifest file (option m) as 
specified within mainClass.txt, naming the JAR file (option 
f) as example.jar and including everything that matches the 
pattern *Class



 

------------------------------------------------------------
--------------------

Running An Executable JAR From Command Line
---------------------------------------------
I can run it from the command line like this:

   java -jar example.jar



 

------------------------------------------------------------
--------------------


Running An Executable JAR From Explorer (Windows)
-------------------------------------------------

Within Windows, it is also possible to set up Windows 
Explorer so that you can double click on the JAR file icon 
to execute the file (handy for GUI applications). The first 
thing you must do is set up the correct association with 
the 'javaw.exe' application that JDK for Windows will have. 
Click here for an older example with pictures! Open Windows 
Explorer and select Tools | Folder Options | File Types.

If there is no JAR file type, create it. Give it a 
description like 

   jar - Executable Jar File
to ensure it sorts under 'jar'. Create or edit the action 
called "open" and associate it with the following action: 

   "C:\Java\jdk1.4.0\bin\javaw.exe" -jar "%1"
Of course, you will replace "C:\Java\jdk1.4.0
\bin\javaw.exe" with whatever path is correct on your 
machine.

IMPORTANT: include the double quotes to take care of names 
with spaces.

If you are using something other than Windows and you know 
how to set up an association in your OS, please contact me.

yes

Jabez is correct, but I also think it is wise to note that 
most of the newer java installers will set up the JAR 
association for double clicking within explorer 
automatically. 

don't forget to add the java bin folder to your Path 
environmental Variable!

using a static block you can print the message (string)s.o.p

use a constructor and declare a global object.

class message
{

      public:
     message("Hello world\n");
}a;
void main(){}

class testing{
    public testing(){
	System.out.println("Hello ");
    }
}
public class TestClass{
    static testing t = new testing();
    public TestClass(){
    }
}

class testprint 
{
	static String print=testprint.toString("test");
	public static String toString(String s)
	{
		System.out.println("I am Here");
		return s;
	}
}

public class classWithoutMain {
	private static int x = load();
	private static int load() {
		System.err.println("This message will be printed");
		System.exit(0);
		
	}
}

Sorry. Missing return statement in the former post

public class classWithoutMain {
	private static int x = load();
	private static int load() {
		System.err.println("This message will be printed");
		System.exit(0);
		return 0;
	}
}
