How to read domain information in java

I need a java code implemented as follows.
When the java code runs in a particular machine, the domain which this machine belongs needs to be read.
The domain information can be easily retrieved using the wmi. But how java can implement it?
Thanks in advance.

WMI stands for Windows Management Instrumentation (WMI). We can view or manipulate any information made available through WMI (including the domain information) through vbscript. In order to retrieve the informationthrough wmi, the vbscript needs to be launched in the java.
Do we have a java's native way to retrieve domain from windows machine?

How to read system eventlog using java program in windows?
is there any java class available to do this ? or any one having sample code for this?
Your friend Zoe

Hi,
There is no java class for reading event log in windows, so we can do one thing we can use windows system 32 VBS script to read the system log .
The output of this command can be read using java program....
we can use java exec for executing this system32 vbs script.
use the below program and pass the command "eventquery"
plz refer cscript,wscript
import java.io.*;
public class CmdExec {
public static void main(String argv[]) {
try {
String line;
Process p = Runtime.getRuntime().exec("Command");
BufferedReader input =
new BufferedReader
(new InputStreamReader(p.getInputStream()));
while ((line = input.readLine()) != null) {
System.out.println(line);
input.close();
catch (Exception err) {
err.printStackTrace();
This sample program will list all the system log information....

How to read SGML files using Java

I've got a text categorisation test collection called Reuters-21578 for my Information Retrieval project. It is distributed in 22 files. Each of the first 21 files (reut2-000.sgm through reut2-020.sgm) contains 1000 documents, while the last (reut2-021.sgm) contains 578 documents. The files are in SGML format. Each of the 22 files begins with a document type declaration line:
<!DOCTYPE lewis SYSTEM "lewis.dtd"> The DTD file lewis.dtd is included in the distribution. Following the document type declaration line are individual Reuters articles marked up with SGML tags.
My questions is how to write a java program to read those 21578 documents or transform them into 21578 seperated text files.

I guess I missed something. What is Renes link?. The
parser stuff isn't really what I'm looking for. I'm
a new at and just learning java and I just want to
know the easiest way to read a SGML file. Should I
use a buffered Reader with a Pushback Input Stream?Hang on.....you want to just read the file without intelligently extracting the SGML data contained within and so have no need of a parser?
Well, in that case, its just text.....so just use BufferedReader or whatever to read the text data. If I understand you correctly, all you really wanted to ask was "how do I read a text file?"

How to set proxy information in JAVA.NIO framework MINA or Netty?

Hi all,
THERE IS NO PROXY SUPPORT VIA JAVA.NIO.
How to use MINA or Netty,other framework support proxy?
Thanks in advance!

The forum is focus on questionNo. The forum is provided by Sun and latterly Oracle to talk about core Java programming: in this case the Java networking APIs. Questions about 3rd party products should be directed to the people who supply them. And asking questions in places where the relevant expertise isn't concentrated is not a rational strategy.
I think you really need patience as a professional expert.Expert, yes. Professional? Is somebody paying me to post here?
And don't talk to me about patience. You have already completely exhausted any patience I may ever have had by repeating a question five times after I had already answered it. Judging by the below you are now in the process of repeating that process.
The information is shared by anybody.Correct, including me, and including the information that there are better places to ask than here about 3rd party products.
Besides, I think I submitted right question on right place.Then once again you are proving yourself incompetent, as I have already told you that it isn't the right place.

How to read Excel file in java

Respected sir/madam
I want to read the values from Excel file in Java program. How can I do that. When I searched over the net I came to know that you can treat Excel file as a Database and write the code as u write for making DB connections .
I did that but i am getting the following error ..can anybody please help..
This is the code what i have written
import java.io.*;
import java.sql.*;
public class ReadExcelFile {
Connection c;
Statement stmnt;
public void checkABA_Number()
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
c = DriverManager.getConnection("jdbc:odbc:ExcelTest","",""); // ExcelTest is the DSN name
stmnt = c.createStatement();
ResultSet rs = stmnt.executeQuery("select * from abadata"); // abadata is my Excel file name
while(rs.next())
System.out.println(rs.getString(1)+" "+rs.getString(2));
}catch(Exception e)
System.out.println(""+e.toString());
finally
try
stmnt.close();
c.close();
catch( Exception e )
System.err.println( e );
public static void main(String[] args)
new ReadExcelFile().checkABA_Number();
My Excel file starts from the first row and first column and also the first row contains the names of the column.
It give me the following error..
java.sql.SQLException: [Microsoft][ODBC Excel Driver] The Microsoft Jet database engine could not find the object 'abadata'. Make sure the object exists and that you spell its name and the path name correctly.
How can I deal with this.?I have properly selected the worksheet while giving the DSN . Is there any versionig problem with Excel or some drivers are in appropriate..and yes i chose Microsoft Excel Driver (.xsl) from ODBC .
I created System DSN.
Can anybody please help me with this ? I will be very gratefull for replies
Thanks in advance

here is the code to read excel file
public void readexel(String filename)
Connection c = null;
