Excellent!!! Thanks Rob. Link you provide is spot on.

This worked perfectly fine.

public void mouseEntered(MouseEvent e) { if (table.isEditing()){ table.getCellEditor().stopCellEditing(); } }

Just click on any column directly from the editing cell. Don't click on any other cell.

Please find the attached screenshots.

1)Edit the value in cell, without doing anything else, click on any column.

2)If click on any column, you can see in 2.png screenshot “my message” has disappeared

3)But If you click on any other cell, the value “my message” retains as in 3.png

Hi,

I am facing some peculiar issue with JTable.

Change value of a cell, without clicking on anywhere else, directly click on column (or) try to expand column size, value you entered in that cell vanishes. But if you click on any other cell instead of expanding column size, value will remain in cell. Not really sure how to fix this issue. I am clueless Please suggest.

class SimpleTableExample extends JFrame { // Instance attributes used in this example private JPanel topPanel; private JTable table; private JScrollPane scrollPane; // Constructor of main frame public SimpleTableExample() { // Set the frame characteristics setTitle( "Simple Table Application" ); setSize( 300, 200 ); setBackground( Color.gray ); // Create a panel to hold all other components topPanel = new JPanel(); topPanel.setLayout( new BorderLayout() ); getContentPane().add( topPanel ); // Create columns names String columnNames[] = { "Column 1", "Column 2", "Column 3" }; // Create some data String dataValues[][] = { { "12", "234", "67" }, { "-123", "43", "853" }, { "93", "89.2", "109" }, { "279", "9033", "3092" } }; // Create a new table instance table = new JTable( dataValues, columnNames ); // Add the table to a scrolling pane scrollPane = new JScrollPane( table ); topPanel.add( scrollPane, BorderLayout.CENTER ); } // Main entry point for this example public static void main( String args[] ) { // Create an instance of the test application SimpleTableExample mainFrame = new SimpleTableExample(); mainFrame.setVisible( true ); } }

Thanks,
Ravi

i tried with String array too.
String st[] = {"move","sourcefodler","destinationfolder"};
Runtime.getRuntime().exec(st);

This also gives the same error :-(

Hi everyone,

I have to zip all the files in a folder which has the timestamp more than 90days, for this i want to move all the files to a filder which ever has > 90days timestamp, to achive this i have used IO package, but the original time stamps of the files are changing to current date, to avoid this i started writing code in native "move" command, like below:

public class Sample { public static void main(String arg[]) { System.out.println("Process Started"); //dateDifference(); String para = "C:" + File.separator + "Documents and Settings" + File.separator + "Ravi" + File.separator + "Desktop" + File.separator + "repo"+ File.separator + "xyz.xls"; String para1 = "C:" + File.separator + "Documents and Settings" + File.separator + "Ravi" + File.separator + "Desktop"+ File.separator+"ArchiveJar"; String command = "move "+para+" "+para1; try { System.out.println("begin"); Runtime.getRuntime().exec(command); System.out.println("end"); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } }

I am getting the below error, please help:

java.io.IOException: Cannot run program "move": CreateProcess error=2, The system cannot find the file specified
at java.lang.ProcessBuilder.start(Unknown Source)

No able to correlate with my requirement, any example would be helpful ?

If not DecimalFormat class, is there anything else which will full fill my requirement.

Thanks,
Ravi

Hi All,

I did lot of google for my answer, no where i found anything:

import java.text.DecimalFormat; public class Currency { public static void main(String str[]){ DecimalFormat format = new DecimalFormat("#,###,###,###.00"); double doe = 123.999; System.out.println(format.format(doe)); } }

Expected result is : 123.99, but i am getting 124.00 (doing round up)

Please help.

Hi All,

onMessage of MDB is not invoked, please correct me if i am doing wrong?

package com.ejb3.jms; import javax.ejb.Stateless; import javax.jms.Connection; import javax.jms.ConnectionFactory; import javax.jms.MessageProducer; import javax.jms.Session; import javax.jms.TextMessage; import javax.naming.InitialContext; @Stateless(name="firstJMSCode") public class FirstJMSCode implements FirstJMSCodeInter{ /* @Resource(name="jms/raviConnectionFactory") private ConnectionFactory confactory; @Resource(name="jms/raviQueue") private Destination destination;*/ public void sendMessage(String msg){ Connection con = null; Session session = null; try{ System.out.println("message is ::"+msg); InitialContext init = new InitialContext(); javax.jms.Queue destination = (javax.jms.Queue) init.lookup("raviQueue"); System.out.println("destination ::"+destination); //get reference to the ConnectionFactory ConnectionFactory confactory = (ConnectionFactory) init.lookup("raviConnectionFactory"); System.out.println("confactory ::"+confactory); con = confactory.createConnection(); session = con.createSession(false, Session.AUTO_ACKNOWLEDGE); MessageProducer msgproducer = session.createProducer(destination); TextMessage textmsg = session.createTextMessage(); textmsg.setText(msg); textmsg.setStringProperty("RECIPIENT","MDB"); System.out.println("message sent"); msgproducer.send(textmsg); session.close(); con.close(); }catch(Exception e){ e.printStackTrace(); } finally{ } } }

MDB code as follows:
package com.ejb3.mdb; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; import weblogic.ejbgen.MessageDriven; /*@MessageDriven(activationConfig={ @ActivationConfigProperty( propertyName="destinationType", propertyValue="javax.jms.Queue"), @ActivationConfigProperty( propertyName="destination", propertyValue="raviQueue"), @ActivationConfigProperty( propertyName="acknowledgeMode", propertyValue="Auto-acknowledge")}) */ @MessageDriven(ejbName="FirstMDBCode", destinationType="javax.jms.Queue",destinationJndiName="raviQueue") public class FirstMDBCode implements MessageListener { public void onMessage(Message msg) { System.out.println(this.getClass().getName() + " called..."); TextMessage textmsg = (TextMessage)msg; try { System.out.println("Message from MDB ::: "+textmsg.getText()); } catch (JMSException e) { e.printStackTrace(); } } }

Weblogic version : 10.3

my system.out.println messages are as below:
message is ::my FIRST JMS message
destination ::raviJMSModule!raviQueue
confactory ::weblogic.jms.client.JMSConnectionFactory@10a4d6b
message sent

if you see MDB messages are not fired

Thanks,
Ravi

Hi All,

Does anybody know a good material for JPA, i am preparing for CX-310-091.
I started reading EJB 3 in Action, JPA part is bit confusing, all JPA has been dumped at one place (personal opinion).
EJB3.0 is very well covered in this book in sequence order, couldn't find the same approach for JPA, i felt so.

any better material or book for JPA ?

Thanks,
Ravi
