How to read configuration data from an xml file (not web.xml)?

Hi,
I want to separate the application specific configuration parameters in a separate xml file and read them as and when they are needed? I know that I can use the wb.xml but I want to separate them in a different xml file because I don't want the web.xml file to be played around later after deployment. If any change is needed then it should be done in the application-config.xml.
How can I read the parameters from this xml file in my jsp code and also what should be the location of this file if I have
../webapps/Root/application
directoty structure ?
Any help is greatly appreciated.

can you give an example of a property file and also
it is loaded in the jsp ?Hmm... loading properties in a JSP is not a very good idea. You should do it in a separate class, rather than mixing the logic with the display logic.
Properties properties = new Properties();
properties.load(UtilClass.class.getResourceAsStream("config.properties"));
// Add a try - catch block around the load
// for IOException...

How to read the data from an excel file into MYSQL by java language

Hi all,
I have some data in excel spread sheet and I want to put the data into MYSQL data base. I created the tables in MYSQL> How can I write a program in JAVA that puts the value from excel sheet to mysql??
I would appreciate your help
regards

By typing code at the keyboard... but presumably you meant to ask what code you should type.
To get data out of Excel there are a few alternatives. The Google keywords I would use to find them are "java excel". I use Apache POI but there are other possibilities, I believe. As for getting the data into MySQL once you have extracted it from Excel, you would use JDBC. But you already knew that, didn't you? You did find the JDBC forum.
In general it's better to ask a specific question on a forum. If you don't have a clue (which is the way we all start out) then just telling people that isn't going to be helpful. The best you're going to get is links to tutorials, which you could perfectly well have found for yourself by simple web searches.

Import data from excel/csv file in web dynpro

Hi,
Here are the basic steps needed to read data from excel spreadsheet using the Java Excel API(jExcel API).
jExcel API can read a spreadsheet from a file stored on the local file system or from some input stream, ideally the following should be the steps while reading:
Create a workbook from a file on the local file system, as illustrated in the following code fragment:
          import java.io.File;
          import java.util.Date;
          import jxl.*;
         Workbook workbook = Workbook.getWorkbook(new File("test.xls"));
On getting access to the worksheet, once can use the following code piece to access individual sheets. These are zero indexed - the first sheet being 0, the second sheet being 1, and so on. (You can also use the API to retrieve a sheet by name).
          Sheet sheet = workbook.getSheet(0);
After getting the sheet, you can retrieve the cell's contents as a string by using the convenience method getContents(). In the example code below, A1 is a text cell, B2 is numerical value and C2 is a date. The contents of these cells may be accessed as follows
Cell a1 = sheet.getCell(0,0);
Cell b2 = sheet.getCell(1,1);
Cell c2 = sheet.getCell(2,1);
String a1 = a1.getContents();
String b2 = b2.getContents();
String c2 = c2.getContents();
// perform operations on strings
However in case we need to access the cell's contents as the exact data type ie. as a numerical value or as a date, then the retrieved Cell must be cast to the correct type and the appropriate methods called. The code piece given below illustrates how JExcelApi may be used to retrieve a genuine java double and java.util.Date object from an Excel spreadsheet. For completeness the label is also cast to it's correct type. The code snippet also illustrates how to verify that cell is of the expected type - this can be useful when performing validations on the spreadsheet for presence of correct datatypes in the spreadsheet.
String a1 = null;
Double b2 = 0;
Date c2 = null;
                    Cell a1 = sheet.getCell(0,0);
                    Cell b2 = sheet.getCell(1,1);
                    Cell c2 = sheet.getCell(2,1);
                    if (a1.getType() == CellType.LABEL)
                       LabelCell lc = (LabelCell) a1;
                       stringa1 = lc.getString();
                     if (b2.getType() == CellType.NUMBER)
                       NumberCell nc = (NumberCell) b2;
                       numberb2 = nc.getValue();
                      if (c2.getType() == CellType.DATE)
                        DateCell dc = (DateCell) c2;
                        datec2 = dc.getDate();
                       // operate on dates and doubles
It is recommended to, use the close() method (as in the code piece below)   when you are done with processing all the cells.This frees up any allocated memory used when reading spreadsheets and is particularly important when reading large spreadsheets.
          // Finished - close the workbook and free up memory
          workbook.close();
The API class files are availble in the 'jxl.jar', which is available for download.

Populate a table reading the data from a TXT file

how can I populate a table reading the data from a TXT file?
thanks

Hey Kevin!
Using FORMS.TEXT_IO to bulk load data from a file strikes me as re-inventing the wheel. It is just about justifiable in a self-service environment, but I regard the EXTERNAL TABLE is a better solution for that situation as well.
The same applies to UTL_FILE. I think the ability to read text with UTL_FILE is primarily intended for read file-based configuration or file manipulation/processing rather than data loading.
Re-writing a text file into SQL statements is too much like hard work (even with an editor that supports macro definition and regular expressions) for no real benefit. You lose all the bulk load peformance you would get from SQL*Loader. But for QAD I'd probably let you off with it.
You missed out one obvious alternative: using Java to turn the contents of an XML file into a CLOB and inserting it into a table which is read by a PL/SQL procedure that parses the XML records and insert the retrieved data into a table.
Stay lucky, APC

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

What is the 'quickest' way to read char data from a txt file

Hello,
What is the 'quickest' way to read character data from a txt file stored on the phone to be displayed into the screen?
Regards

To be even a bit more constructive...
Since J2me does not have a BufferedInputStream, it will help to implement it yourself. It's much faster since you read large blocks at ones in stread of seperate chars.
something line this lets you read lines very fast:
while ( bytesread < filesize ) {
         length = configfile.read( buff, 0, buff.length );
         // append buffer to temp String
         if ( length < buff.length ) {
            byte[] buf = new byte[length];
            System.arraycopy( buff, 0, buf, 0, length );
            tmp.append( new String( buf ) );
         } else {
            tmp.append( new String( buff ) );
         // look in tmp string for \r\n
         idx1 = tmp.toString().indexOf( "\r\n" );
         while ( idx1 >= 0 ) {
            //if found, split into line and rest of tmp
            line = tmp.toString().substring( 0, idx1 );
         /// ... do with it whatever you want ... ////
            tmp = new StringBuffer( tmp.toString().substring( idx1 + 2 ) );
            idx1 = tmp.toString().indexOf( "\r\n" );
         bytesread += length;
      }

Include another xml file in web.xml

I was able to use XML Entity to include another xml file in web.xml for older servlet specifications, i.e.:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" [
<!ENTITY my-web SYSTEM "my-web.xml">
]>
<web-app>
&my-web;
</web-app>This allows me to share my-web.xml among various web applications.
How do I achieve the same thing for servlet specification 2.5, which does not have a DTD but rather an XSD?
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">I am using Glassfish V2UR1. I know about $domain-dir/config/default-web.xml, but for reasons I won't get into I cannot put things in there.

Hi Maksim. I understood that. It's just that I would prefer some method that doesn't require the developers to do something like extracting a file from the EAR file, changing the file and then putting it back in. As you probably know, some developers could handle it and some will most certainly make mistakes.
When they do they come to my group and say "my app doesn't work" and then we have to spend time figuring out why.
Plus, once the developers get used to doing things the automated way they're going to have a hard time remembering to do a manual step each time they do a build.
I have heard that there may be some way to do something similar to this on Visual Administrator. I'm going to investigate that too.
Thanks!

How to read the data from excel file and store into the table?

Hi All,
I have table with BLOB datatype contains a excel file. I have to read that data from excel and store into one table with all the fields in excel.
All the excel fields and my table columns are same.
Can you share with me how can acheive this using LOB's?
Thanks

Hi OraSuirya,
you can try with external tables .
syntax as follows
create table ext_table_csv (
i Number,
n Varchar2(20),
m Varchar2(20)
organization external (
type oracle_loader
default directory ext_dir
access parameters (
records delimited by newline
fields terminated by ','
missing field values are null
location ('file.csv')
reject limit unlimited;
For this you need to create directory
Directory Creation syntax:
create or replace directory ext_dir as 'D:\oracle\user_dir\ext_dir';
grant read, write on directory ext_dir to <User>;
please paste the excel file in the particular directory .
I hope this will help you.
Please correct me if I am wrong anywhere .
Thanks,
Tippu.

I'd like to point out here that any time you have a series of
variables that
all have identical names except for a number in the variable
name, you
should be looking at lists. I'm surprised, Paul, that you
have lists used
to the extent that you're able to use Value[counter] on the
right side of
the equation, yet you're not using lists on the left side of
the equation.
Let's look at how this code could be made super simple by
having ONE list
variable, LessonComplete, instead of Lesson1Complete through
Lesson8Complete.
-- Assumes a database query returns a string of name=value
pairs
-- delimited by the ampersand (&) character.
-- strip leading & from queryString
--(note you could also not add this ampersand on the PHP
side)
queryString := SubStr(queryString, 1, CharCount(queryString))
-- break into list of individual lines
tempList := Replace("&", Return, queryString)
listLength := LineCount(tempList)
-- create empty arrays for name and value
name := Array("", listLength)
LessonComplete := []
repeat with counter := 1 to listLength
singleLine := GetLine(tempList, counter)
name[counter] := GetWord(1, Replace("=", " ", singleLine))
LessonComplete[name[counter] * 1] := GetWord(2, Replace("=",
singleLine))
end repeat
-- now you will need to add a separate calc icon with a
routine to
-- read the data from the arrays. name[counter] matches
value[counter]
--No you don't...You're DONE :-)
Also note that this is extensible...you can have Lesson 9,
10, etc. and not
have to change the code. You can also lower the amount of
data being
transmitted, because now instead of Lesson8Complete=1 all you
need is 8=1.
This lowers the server load and speeds the response. It has
advantages on
the Authorware side as well, because if, for instance, you
had a series of
buttons that were checked or not based on the completion, you
could do the
same type of loop. Separate variable names do not allow for
that type of
loop unless you use Eval (ugh).

HI Martin,
i am not realy sure what you want!?!?
i think you want to display only a part of the values you read from XYZ
so what you can do:
write all the values in an array.
the size of the array is the max. value of the slide bar
now you can select a part of the array (e.g. values from 100 to 200) and display this with a graph
the other option is to use the history function of the graphes

How to retrive the data from a sqlite file(.db3) in windows phone 8.1(runtime)

hey guys
i installed the sqlite and sqlite-net as requested in other answers i found, changed to x86, and add the .db3 file in my project.
but the problem is how to retrive the data that already in the file( i am not creating any table or data in the app, just read)
all the answer i found is to create a table first and then read the table, i tried to skip the step of creating a table, and read from the table directly, but failed with " no such table", by the way, i set the property of the .db3 file as "content",
"copy if newer"
can anyone please help? i appreciate that !

Hello,
From your description, you want to read data from available sqlite file. When you add the sqlite file into your project, you need to change the sqlite file build action to content. After deploying to device, the sqlite file is located in installation folder,
you need to copy that file into storage folder before reading data. Please try the following code snippets.
private async void Button_Click_9(object sender, RoutedEventArgs e)
//check if file exists in storage folder, and then copy to local storage
bool flag = await FileExistsAsync("Data.db3");
if (!flag)
var folder = await Package.Current.InstalledLocation.GetFileAsync("Data.db3");
await folder.CopyAsync(Windows.Storage.ApplicationData.Current.LocalFolder);
// open sqlite and read data
public async Task<bool> FileExistsAsync(string fileName)
try
await Windows.Storage.ApplicationData.Current.LocalFolder.GetFileAsync(fileName);
return true;
catch (FileNotFoundException)
return false;
