How to read a trace file?

Can someone point me to a good resource where I can learn how to read a trace file? I have read somewhere that TKPROF can leave some things unattended. Worse, it reports things incorrectly.

I usually recommend use Trace Analyzer (TRCA), Note:224270.1
It includes all the details found on TKPROF, plus additional information normally requested and used for a transaction performance analysis. Generated report is more readable and extensive than text format used on prior version of this tool and on current TKPROF.

How to use forms trace file for performance tuning

I am trying to use forms trace file in order to find cause of forms application performance problem.
I have read the document B14032-03 where is described how to turn on tracing and how to convert binary trace file to xml or html format. However these xml/html files are useless because they only contain series of forms events, without possibility for grouping or sorting. Actually, they are like to database raw trace file. I need some tool, like tkprof for database trace, that will process xml/html file and generate some more useful format.
Further, I have tried to load forms trace file into relational database tables in order to use SQL for performance problem investigation. I have followed procedure described in document A92175-01, but without success.
Is there any way to process xml/html file with grouping, orderering or summing event duration or way to load either binary, xml or html trace file into structured data in database.

It's not : elegant at all to thank people 4 No help,it's not their problem that u don't search enough, or u don't have access to db.
We should always say thank ,or 'Jazak Allah Khiern' on both cases even they could or couldn't help u.
Finally,i expect ' an appologize or even a thankful word ' and the kindness i am sure u had to publish the solution u found in order to share it with people who had same problem or at least to give them the info to get the appreciation or the thanksful word u deserve.
Rem.Never give a bad feedback to people who tried to help u.

Read and write one text file is not a problem, but what confusies me is how to read several text files at one time, in the meanwhile,
is it possible to display the name of the text file?
For example, assuming I want to load file" cha 1, cha 2 , cha 3, " at one time and show their names, how to hadle with it
I have reviewed some files and it is not helpful

Either with a 'for' loop like in the lib you have attached, or like this attached VI

How to read multiple dat files.

Hello Everyone!
I am working on a project that requires one file that creates a JFrame with a current file title, JTextFields that accesses two .dat files and a JButton.
The user clicks a JButton to cycle through the first sequential .dat file. When the end of the first file is reached the file is closed, the JFrame title is changed to the second file title as the user continues to click the JButton to continue on viewing the second file?s records, until the second reaches the end of file.
The project requires using Try-Catches to catch the EOF exceptions and IOExceptions and Thread or Runnable.
I have been able to get one file to read and display its records; however, researching back through my text on how to read/write to files I haven?t been able to determine how to get to the end of the file and proceed to the next file without triggering the EOFException. I have even tried multiple Try-Catches (one for each file within the actionPerformed method) and that ends up ignoring the first file records and only displays the second files records.
This is a school project and we have only covered just the bare basics of Java over the last two months. So, any hints that anyone can provide can only be of what type of procedure will be needed or what procedure won?t help to complete the task, without giving away the solution.
I have spent approximately 40 hours of study time on this project and believe that I have definitely run into a major snag.
The following is the code I have so far:
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class StudentRead extends JFrame implements ActionListener
   private JLabel gradStudentList = new JLabel("GRADUATE Student List");
   private JLabel undergradStudentList = new JLabel("UNDERGRADUATE Student List");
   private Font bigFont = new Font("Helvetica", Font.ITALIC, 24);
   private JLabel userprompt = new JLabel("View the students");
   private JTextField idNumText = new JTextField(4);
   private JTextField lastNameText = new JTextField(15);
   private JTextField firstNameText = new JTextField(15);
   private JButton viewRecordButton = new JButton("View Record");
   private JLabel idNumberLabel = new JLabel("ID Number");
   private JLabel lastNameLabel = new JLabel("Last name");
   private JLabel firstNameLabel = new JLabel("First name");
   private Container con = getContentPane();
   DataInputStream gradStudentInStream;
   DataInputStream undergradStudentInStream;
   public StudentRead()
      super("Read Student Records");
      try
         gradStudentInStream = new DataInputStream(new FileInputStream("GradStudents.dat"));
         undergradStudentInStream = new DataInputStream(new FileInputStream("UndergradStudents.dat"));
      catch(IOException e)
         System.err.println("File not opened");
         System.exit(1);
      setSize(325, 200);
      con.setLayout(new FlowLayout());
      gradStudentList.setFont(bigFont);
      con.add(gradStudentList);
      con.add(userprompt);
      con.add(idNumberLabel);
      con.add(idNumText);
      con.add(lastNameLabel);
      con.add(lastNameText);
      con.add(firstNameLabel);
      con.add(firstNameText);
      con.add(viewRecordButton);
      viewRecordButton.addActionListener(this);
      setVisible(true);
      setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   public void actionPerformed(ActionEvent e1)
      String lastName, firstName;
      int IdNum;
      try
         IdNum = gradStudentInStream.readInt();
         lastName = gradStudentInStream.readUTF();
         firstName = gradStudentInStream.readUTF();
         idNumText.setText(String.valueOf(IdNum));
         lastNameText.setText(lastName);
         firstNameText.setText(firstName);
      catch(EOFException e2)
         closeFile();
         System.exit(0);
      catch(IOException e3)
         System.err.println("Error reading file");
         System.out.println("out");
         System.exit(1);
   public void closeFile()
      try
         gradStudentInStream.close();
         System.exit(0);
      catch(IOException e)
         System.err.println("Error closing file");
         System.exit(1);

How to read a text file using Java

Guys,
Good day!
Please help me how to read a text file using Java and create/convert that text file into XML.
Thanks and God Bless.
Regards,
I-Talk

     public void fileRead(){
             File aFile =new File("myFile.txt");
         BufferedReader input = null;
         try {
           input = new BufferedReader( new FileReader(aFile) );
           String line = null;
           while (( line = input.readLine()) != null){
         catch (FileNotFoundException ex) {
           ex.printStackTrace();
         catch (IOException ex){
           ex.printStackTrace();
     }This code is to read a text file. But there is no such thing that will convert your text file to xml file. You have to have a defined XML format. Then you can read your data from text files and insert them inside your xml text. Or you may like to read xml tags from text files and insert your own data. The file format of .txt and .xml is far too different.

Hi Vijay,
You can try this piece of code too:
Properties props = new Properties();
//try retrieve data from file
//catch exception in case properties file does not exist
try {
         props.load(new FileInputStream("c:\property\Test.properties")); //File location
         String serverName = props.getProperty("servername"); //Similarly, you can access the other properties
         if(serverName==null)
           //....do appropriate handling
     }     catch(IOException e)
               e.printStackTrace();

2. Learn the basics of programming java.
3. Learn about java.io.*
4. Learn about java swing
5. Find documentation that describes the format of the ARPA file.
6. Read the documentation and understand it.
7. Find a source for ARPA files (if this is online then there is more java to learn as well.)
8. Use 1,2 and 3 to write java code that consumes the ARPA file.
9. Use 4 to ask the user for a word.
10. Use 1 and 2 to write code that 'searches' what you read in 8.

If you cannot disable the tracing for some reason, consider setting maximum file size for the dump.

How to read from properties file

pls tell me how to read from .properties file.

I think i have mixed it up :)
I have looked at it again and believe you are using regular JSP portlets.
Can you tell what you want to achieve by reading .properties file. Are you meaning the preferences of the portlet or what exactly are you trying to do?
Reading propertie files is easy:
// Read properties file.
Properties properties = new Properties();
try {
properties.load(new FileInputStream("filename.properties"));
String myKey = properties.getProperty("yourKey");
} catch (IOException e) {
