I have a JSP code which will open the contents of a excel file.
Now i need this contents of the excel file to be added dynamically to a table in the sameJSP. How to proceed.At the maximum 10 rows can be added dynamically.
Assuming i have a table in JSP which has heading first name,last name,DOB and Gender. After opening the excel through JSP the contents needs to be iterated and added to the columns mentioned.
I have `country.properties` file which have values as follows:
1=USA
91=India
20=Egypt
358=Finland
33=France
679=Fiji
and, have a response class file, which is setting a response from database to display it on `JSP` file. The value that I am getting from database is in the form of `code` or `integer`. I needed to have that value from the database and before setting the response I need to use `getProperty(code)` and save the String representation of that code into a new list and then pass that list to `setResponse`. For e.g: This is the value I am getting from database:
col1 | col2 | col3 |
1 helo done
I needed to show on my JSP page as:
col1 | col2 | col3 |
USA helo done
I was following this tutorial [URL].... but not able to exactly understand how to achieve the same.
This is my `DAOImpl` where I needed to `iterate` and save the `mapped key-value` in a new list and then pass to `JSP` page
public class CountDAOImpl implements IDataDAO {
private Connection conn = null;
private Statement statement = null;
private ResultSet rs = null;
private List<String> country_code = new LinkedList<String>();
[Code] ....
How can I read a text file present in my local directory say (C://test.txt) , iterate and populate the values of test.txt into a text area of the JSP page?
Contents in the test.txt file:
username:test
password:test123
domain:test321
DBname:testDB
I am a beginner in Java and I have a task of reading excel document and converting it into a text file.

Not sure why this code isnt working for me, it makes an empty excel file called output, but never copies the contents in "myfile" to that output file. I have Excel 2010 but I saved both of them as 97-2003 workbooks. Am I missing something? Do you have to go cell by cell to copy an excel file with JXL?

With Apache POI it is possible to password protect an excel file. PFB for the code. But it is working with XLSX extension [2010 Excel format], But not with XLS [2003 Excel format].how to accomplish the same
package com.excel.utility;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.security.GeneralSecurityException;
[code]..
I'm using Apache Poi to create an Excel file from a JTable.
I want to open the file directly in Excel, rather than first write it to disk and then open it from the disk.
FileOutputStream output = new FileOutputStream( StolleExcel.xls" );
workBook.write( output );
Desktop dt = Desktop.getDesktop();
dt.open( new File( "StolleExcel.xls" ) );
output.close();
Is there a temporary way of saving the Excel object then just opening it with Excel, so the user can save or edit whatever they want?

Label label = new Label(0,2,"A label record");
sheet.addCell(label);

I need to print contents of database to excel file.Apache POI is the solution but I am not finding a way to print the DB column names/headers into the excel.
E.g.:
incase csv we have opencsv CSVWriter writer = new CSVWriter(new FileWriter(fileName));
System.out.println("writer");
writer.writeAll(rs, true);
will print the db contents with the column headers dynamically whatever the query may be.
Any solution where we can print data and column names without know the query previously as we are getting query at the run time and each time the query is different.

Emp Id. Emp Name

We have restarted server, system but still problem exists. We found that there is no code level or data base level or network level issues.
Now we have to see server level issue. What are the factors which effects the file downloading at server level.

I have an XML sheet and my project is top retrieve the required elements from XML sheet. So my format of XML was like follows:
<Class>
<Employees>
<EMPLOYEE>
<ENum> Abc123</ENum>
<Ename> John<?Ename>
<EType>Mathematics</EType>
[Code] ....
I have used unmarshalling concept to retrieve the data elements... I have to check whether the elements satisfy few regulations when compared with data in Database. So, i thought of grouping the employees depending on EType. I have created a Map with linkedlist of employees. Say Map<String, LinkedList<Employe>>EmpMap=new Map<String, LinkedList<Employe>>();
I have already created a class named Employee which has all the setter and getter methods for employee.
Here am going to take Etype(Employee type) as key and linkedlist(list of employees of certain type) as value. How to iterate these linked lists and place them in my Map.
