Read, Write and create files from java applet.

Dear All,
I have created a two files. One is applet and one application file. I am creating a instance of application file in applet. Application file is used for reading, writing and creating files. When I invoke applet from broser it dipslays error wrt file access permission. From the forum search I know that we need to sign the applet / edit the java policy to run the code locally. Final delivery of my code should execute on different system. Its not web. I have created a html page on submitting the form it invokes applet to read the form values from param and needs to update the values in xml file located locally. Please help me on how I can proceed with this fix.
Thanks in advance.

Sorry if I have not stated the problem clearly. I need to update content to files hosted in local system using java applets.
I belive there are two ways to achive that.One with jar signer and one with modifying the java policy file. But this application needs to be installed in different system locally as I have created a application with webpage as useinterface and need to update the content in local files on submission. Not sure on how to modify the java.policy files in each end user system and whats the value we need to update in java policy file. Please help me on the steps to be followed

Read & write from external files in java

Hello everybody,
I need your help in two problems. I have to write a method that read specific numbers from a file, save them in an array, do some calculation on that array and write it again in a new file.
For example, I have a file that contains the following:
#VRML V1.0 ascii
Material {
diffuseColor [ 1 1 1 ]
ShapeHints {
vertexOrdering COUNTERCLOCKWISE
shapeType UNKNOWN_SHAPE_TYPE
Coordinate3 {
point [
          1 0 0 ,
          1 1 0 ,
          1 1 1 ,
          1 0 1 ,
          0 1 0 ,
          0 1 1 ,
          0 0 1 ,
          0 0 0 ,
IndexedFaceSet {
coordIndex [
0,1,2,-1,
0,2,3,-1,
1,4,5,-1,
1,5,2,-1,
3,2,5,-1,
3,5,6,-1,
0,3,6,-1,
0,6,7,-1,
6,5,7,-1,
7,5,4,-1,
0,7,4,-1,
0,4,1,-1,
I need to read the point coordinates only and save them in a two dimension array, then I'll do some transformation on that array and write it in a new file that contains the previous data but the point coordinates are the transformed coordinates. I tried the following:
FileReader in = new FileReader("C:\\hexahedron.txt");
          BufferedReader br = new BufferedReader(in);
          String line;
          StringTokenizer s;
          int [][] point = new int [8][3];
          int row = 0;
          int column;
          while ( (line = br.readLine()) != null) {
               s = new StringTokenizer(line);
               column = 0;
               while (s.hasMoreTokens()) {
                    if ( s.nextToken() == "[" ){
                         point [row][column++] = Integer.parseInt(s.nextToken());
               row++;
          br.close();
          in.close();
But when I tried it, I found out that it saves 0s in the array!
As I mentioned before, my problem is that I don't know how to read specific information from a file. I know how to write new information a file, but how to write a file that I already have with changed specific information.
I'll be grateful if you show me how to solve those problems.
And I hope that I explained my problems in an understandable and clear way.
Regards,

if ( s.nextToken() == "[" ){should beif (s.nextToken().equals("["){Also, you have two nextToken for each has hasMoreTokens, which is going to cause an exception.
You are never hitting the parseInt code because of your equals/== error. Therefore, everything is zeros.
The order of reading lines and checking for "[" isn't right. You should find the [ (maybe including the "point" word), then get numbers from the following lines (read line, tokenize, read line, tokenize, ...) until you hit the end of the points.

hi,
everyone, i meet a problem.i want to write a excel
el file use java.i can use .csv input the date to
excel.but i want to know how to format it.
thanks
JoveIf I understand your question correctly you need to know the format of a .csv file for use in an Excel spreadsheet. A .csv file is a comma-delimited file so all that you need to do is write your data elements to the file with commas in between them. Having done something similar in the past, let me warn you that when Excel is reading your file, it uses some characters other than commas as field delimiters. for example, / : and ; are treated as commas. To defeat this, you will need to surround fields containing those characters in double quotes.
Hope that helps

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;

I took your code and reworked it to access a little database I keep of students at a small private school where my wife works. The Student table has columns "studentID", "firstname", "lastname", and "gradyear".
Running your code for the output got the following. I cut and pasted the output after it had run through the first 4 students, so you can see what it's doing.

<b>Hi
i can explain you to read data from Excel file
First You have to download the jxl.jar file. You can get this file from the Below site
</b><a href="http://www.andykhan.com/jexcelapi/download.html">jexcelapi jar</a>
It will be in Compressed Fromat So Unzip it to get the Contents
After Unzipping The File You will get a Folder (jexcelapi/jxl.jar)
Now in NWDS open web dynpro explorer, Right Click Your Project, a popup menu will appear and in that click Properties
You will get window displaying your Project Properties
On Left Side of the window You Will Find "Java Build Path"
Click That "Java Build Path" and you will get 4 Tabs Showing ( Source,Projects,Libraries,Order and Export)
Click Libraries Tab
You will find options many options buttons
In that click the Button "Add External Jars"
You will get Window in order to fecth the jxl.jar file from the location you had stored
After selecting the jxl.jar i will get displayed and click ok
Now Open Navigator
Open Your Project
You will find Lib folder
Copy the jxl.jar to that lib folder
Note : You cannot Read the Content from the excel file directly
First You Have to copy that file to the Server,
And from the Server you can get the file absolute path
With the absolute path you can read the contents of the Excel file
You have to save the Excel file as .xls Format and Not as xlsx format i will not accept that...
You have Upload the Excel file from the Server Using the File Upload UI Element
This Coding will extract 3 columns from the Xls File

Dear All,
There are three ways for achiving excel operations using java including excel to xml etc.
1. There is a very effective tool available for this operation is "jexcel". You can find it at http://www.andykhan.com/jexcelapi/index.html
2. Jakarta site has provided a very good tool by name jakarta poifs. one can find at jakarta site.
3. One can develop a very effective tool by combining these above tools togather.
The operations that can be performed are read, write, convert etc for excel. The major attraction of Jexcel is excel to xml conversion.

How to read/write a binary file from/to a table with BLOB column

I have create a table with a column of data type BLOB.
I can read/write an IMAGE file from/to the column of the table using:
READ_IMAGE_FILE
WRITE_IMAGE_FILE
How can I do the same for other binary files, e.g. aaaa.zip?

There is a package procedure dbms_lob.readblobfromfile to read BLOB's from file.
http://download-east.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#sthref3583
To write a BLOB to file you can use a Java procedure (pre Oracle 9i R2) or utl_file.put_raw (there is no dbms_lob.writelobtofile).
