Hahaha You must be kidding , no body will read this much for you... Make a small demo so we start helping you. Atleast divide them in small task.

//opening Frame B

frameA.setVisible(false);
frameB = new JFrame();
frameB.setVisible(true);
//Or
frameB.setVisible(true);

// Closing Frame B

frameA.setVisible(true);
frameB.dispose();

Just remove your title bar from frame B and provide a close button.

Taking backup is a admin responsibility , i know this. But a small organization cant afford admin whose s/w is completely based on free software.. Taking backup of data even for a small shop is common now a days. So the organization where i m working cant afford a admin. :-)

NVL WORKED, but my problem isnt solved yet

100% Oracle Database...... :) I m making report which take all company name there purchase and sale SUMS and difference, some company can have no sale and purchase so atleast there name must be listed with 0 on both sale and purchase... Thats what all i want.

select companyname,sum(sale) as TotalSale,sum(purchase) as TotalPurchase from invoice group by companyname

I have already modified by query....

Also Nvl dont work.....

Please take my above query and place a outer join in correct manner....

Let me clear it i m making report

Following are the record
Company purchase sale
A 1 1
A 1 2
B 5 7

now the same above query will only show A and B company sale and purchase rest of companies values will be ignored and this is what i dont want.

select companyname,sum(sale) as TotalSale,sum(purchase) as TotalPurchase from invoice group by companyname

I used the above query to get the total sale and purchase belong to following company

A , B ,C ,D ,E ,F ,G

only A,C,E,G have sale and purchase value other have no sale or purchase record.

so I got A 12 13 ,C 12 15 , E 15 89 , G 14 89 but i want rest company to show 0 if there sum of sale or purchase are not present.

Yes u are right as always.... But what about my problem....

it will be very easy for us if u take two or three snapshot of your screen and load here.............

select companyname,sum(sale) as TotalSale,sum(purchase) as TotalPurchase from invoice group by companyname Having companyname IN (select companyname from invoice)

It returns sum only for those column whose all sum are not blank, how can i show blank sum values

I mean there are 7 companies but only 4 records are shown. I want to display all seven.

Found a hard way, but it will work.

Check thread through isAlive Method... and Run another when first finishes.

Click the Src package u have made, i think you must clicked some library and running the application....

Thanx Man....

It will be very kind if u post a sample script.... or just algorithm in post

thank you debasisdas for posting, i already tried that, i m using java to take backup of oracle.... I want user to take backup remotely from any computer.. For exp he must have oracle installed.... Any idea?

How to take a user table backup from that user account? I mean i want to give him grants to take backup... also query to take backup.

Is there any way to take oracle backup from java.

Connection c = // Connection Setting;
st = c.createStatement();
rs = st.executeQuery("//What to write here for backup");

I have tried imp and exp utility , but they cant be accessed through sqlplus...

Thank you peter.... I forget this thing.... It will solve my problem. And dont be angry dude........ Thanx again

I Grabbed the basics from here... Rest is easy

Finally its solved..........................................

1) start from jdk6 ...
2)Best Book: http://www.amazon.com/Java-Complete-Reference-Seventh-Osborne/dp/0072263857
3)Download Jdk From Here: http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u25-download-346242.html
4)Editor: Notepad or Notepad++ for starter, Eclipse and Netbeans for Advance User
5) Also for Api reference : http://download.oracle.com/javase/1.4.2/docs/api/overview-summary.html

Deal all, i am new to reports , i tried BIRT,JASPER,Crystal and oracle reports ... but i m only able to make a report in designer , how to connect to standalone application of java made in java se edition... So please tell me easy report designer because in vb or oracle or vc# connecting report is very easy but in java it doesnt seem this language can do this with that ease.

// First Define "a" outside addTab then add "a", Compiler cant recognize ram a
tab.addTab("RD",ram a);
// Its Listener
b1.addActionListeners(this);
//Implement Action Listener
class abc extends JPanel
{
public abc()
{
txt1=new JTextField(15);
b1=new JButton("submit");
b1.addActionListeners(this);
add(b1);
}
}
// JFrame is not visible to void main function , also u are using Jframe Extend then why a new JFrame.
JFrame frame

See some Java Program's.....

I agree with @jwenting.

re validate before repaint.
Google some example you will get it.

Can u please post what output u are expecting.... If you talking about the error , it is already solved...

import java.io.*;
import java.util.Arrays;
public class r
{
public static void main(String args[])
{
String st[]=new String[30];
int n,k;
String[] names =new String[30];
InputStreamReader isr=new InputStreamReader(System.in);
BufferedReader br=new BufferedReader(isr);
try
{
System.out.print("enter limit:");
n=Integer.parseInt(br.readLine());
for(int i=0;i<30;i++)
	names[i] = new String();
for(int i=0;i<n;i++)
{
names[i]=br.readLine();
}
Arrays.sort(names);
System.out.println(Arrays.toString(names));
}catch(IOException e){}
 
}

Check my post, i already solved your matter. At least i deserve a positive point. ;-)

for(int i=0;i<30;i++)
names[i] = new String();

You cant use things before initialzing....

Output can vary according to your computer's regional settings.

Anuradha, The problem was i wasnt using addRow.. But thanx to mKorbel it corrected. I already used Net Beans , Problem is visual tools dont provide enough controls so its better to code in case of performance matter s/w project's.

import java.util.Date;
    import java.text.DateFormat;
    import java.text.SimpleDateFormat;

    private String getDateTime() {
        DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
        Date date = new Date();
        return dateFormat.format(date);
    }

Format Your Date Structure.

I am new for web desging , i want to learn desging, but dont know where to start from... Which tool is best for desging and easy also... any suggestion , comments will be appreciated.

I already explained that i cant post my emotion with my message, so using word "slapped" isnt nice.... second i dont want 24/7 service but i just want a single to the point reply ..... Again i cant post my emotion with my message.

I never imagined so much replies on a solved threads.... also -1 on asking help. ;-) Thanx mkorbel for a nice lecture. It is one of the best forum, but i think there isnt any professional who used reports with java before else i some one give me a small program to call reports from java for my previous thread responce. ;-)

I already solved it.......

ResultSet res1 = stat1.executeQuery ("insert into client (column names) values ('joker','Miraj',110)" );

Auto Number generated Automatically , insert row directly. MENTION column name in which you want to insert data.

Hello............ Any one there...................................................

And why are u calling loop 3 and 5 times....

import java.io.*;
     
    public class regform
    {
    public static void main(String args[])throws IOException
    {
    BufferedReader br= new BufferedReader (new InputStreamReader (System.in));
    String name = null,course = null,days = null,subject = null,section = null,time = null;
    int unit = 0,ID = 0;
    int ctr=0;
     
    for(ctr=0;ctr<3;ctr++)
    {
     
    System.out.print("\n Enter name: ");
    name=br.readLine();
    System.out.print("\n Enter ID: ");
    ID=Integer.parseInt(br.readLine());
    System.out.print("\n Enter course: ");
    course=br.readLine();
    System.out.print("\n Enter section: ");
    section=br.readLine();
     
    for(ctr=0;ctr<5;ctr++)
    {
     
    System.out.print("\n Enter subject: ");
    subject=br.readLine();
    System.out.print("\n Enter days: ");
    days=br.readLine();
    System.out.print("\n Enter time: ");
    time=br.readLine();
    System.out.print("\n Enter unit: ");
    unit=Integer.parseInt(br.readLine());
     
    }
    }
     
     
    for(ctr=0;ctr<3;ctr++)
    {
     
    System.out.print("\n " + name);
    System.out.print("\n " + ID);
    System.out.print("\n " + course);
    System.out.print("\n " + section);
     
     
    for(ctr=0;ctr<5;ctr++)
    {
     
    System.out.print("\n " + subject);
    System.out.print("\n " + days);
    System.out.print("\n " + time);
    System.out.print("\n " + unit);
    }
     
    }
     
     
    }

You Forget to intialize String var to null.
