You can do your log4j config that:

log4j.rootLogger=debug, stdout, R log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout # Pattern to output the caller's file name and line number. log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n log4j.appender.R=org.apache.log4j.RollingFileAppender log4j.appender.R.File=/home/leonardo/dev/example.log log4j.appender.R.MaxFileSize=100KB # Keep one backup file log4j.appender.R.MaxBackupIndex=1 log4j.appender.R.layout=org.apache.log4j.PatternLayout log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

Already I done something like to do a download .zip file...
But, what do you need to do exactly?

I want Library(JAR) that I can use it to Extract any .Z File or any Method that help me to Extract .Z files

Okay, look this example:

import java.io.*; import java.util.zip.*; class ZipFileUtils { public static void main(String[] args) { if (args.length != 1){ System.out.println("Usage: java testFiles [zipfile path] "); return; }try{ String filename = args[0]; testZipFiles list = new testZipFiles( ); list.getZipFiles(filename); }catch (Exception e){ e.printStackTrace(); } } public void getZipFiles(String filename){ try{ String destinationname = "c:\\servlet\\testZip\\"; byte[] buf = new byte[1024]; ZipInputStream zipinputstream = null; ZipEntry zipentry; zipinputstream = new ZipInputStream( new FileInputStream(filename)); zipentry = zipinputstream.getNextEntry(); while (zipentry != null) { //for each entry to be extracted String entryName = zipentry.getName(); System.out.println("entryname "+entryName); int n; FileOutputStream fileoutputstream; File newFile = new File(entryName); String directory = newFile.getParent(); if(directory == null){ if(newFile.isDirectory()) break; } fileoutputstream = new FileOutputStream(destinationname+entryName); while ((n = zipinputstream.read(buf, 0, 1024)) > -1) fileoutputstream.write(buf, 0, n); fileoutputstream.close(); zipinputstream.closeEntry(); zipentry = zipinputstream.getNextEntry(); } zipinputstream.close(); }catch (Exception e){ e.printStackTrace(); } } }

I want to open a new window,
the problem i am facing is, i cannot send selected row data into a new jsp page using javascript.

Hey, Pall Jain

You can do something like that:


function openNewPage(URL) { var width = screen.availWidth; //that get the actually Width from your window var height = screen.availHeight; //that get the actually Height from your window var left = 0; //the position, relative to left var top = 0; //the position, relative to top window.open(URL,'window', 'width='+width+', height='+height+', top='+top+', left='+left+', scrollbars=no, status=no, toolbar=no, location=no, directories=no, menubar=no, resizable=no, fullscreen=no'); //some options about your window }

So, when you'll edit some row, you can do three things:

1º - Put a button in row, and that button redirect to your jsp or servlet, passing the code for do the research.
2º - Using a link on every rows of your table, redirecting to your jsp or servlet, passing the code for do the research.
3º - You can make a javascript code to insert de id of row selected, when the row is selected, look the example:

function selectRow(id){ var idToSearch = document.getElementById('hidenIdToSearch'); idToSearch.value=id; }


And your JSP:

<form action="yourServletOrJsp"> <table> <tr onclick="selectRow('1')"> <td> //put the values.... </td> </tr> </table> <input type="hidden" value="0" id="hidenIdToSearch"> <input type="submit" value="SEND"> </form>

How to connect JDBC(MySQL) with JPanel.I have a login page or login panel and i want to connect jdbc(MySQL) with that lagin panel for which i can login a person by checking id and password...

Hey man!

You can use a specific class and method responsible for that, look a sample example:

package br.com.cadastro.model.dao; import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; public class DaoFactory { private static final String USER = "user"; private static final String PASSWORD = "password" private static final String DB = "database"; private static final String LOCAL = "localhost"; private static final String PORT = "3306"; public static Connection getCurrentConnection() throws SQLException{ return newConnection(); } private static Connection newConnection() throws SQLException{ //jdbc:mysql://localhost:porta/banco","user","user" String url = "jdbc:mysql://"+LOCAL+":"+PORT+"/"+DB; Connection conn = DriverManager.getConnection(url, USER, PASSWORD); return conn; } }


And you call the method when you need to user, like:

public static void main(String[] args) throws SQLException{ System.out.println(newConnection()); }

Problem i am facing is i am not sufficient good to open the row data using JAVASCRIPT. So Kindly Help me.

Hey man!

Do you wanna open another window to edit the data? Or do you wanna edit data on the same window, like enabling the fields?

Someone solved that?
