If you want to get an "Save as" dialogue, then you need to set the content-disposition in the header to "attachment". The default value is "inline".
Best solution is to create kind of a FileServlet and let it stream the right file as a download to the client. You may find the downloadFile() snippets at the bottom of this article useful: http://balusc.xs4all.nl/srv/dev-jep-pdf.html Put it in a FileServlet and call it using for example .

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.

How to print a text file using Java

How can I print a text file using Java without converting the output to an image format. Is there anyway I can send the characters in the text file as it is for a print job? I did get a listing doing this ... but that converted the text to an image format before printing....
THanks,.

Hi I had to write a print api from scratch, and I did not convert the output to image. Go and read up on the following code. I know there is a Tutorial on Sun about the differant sections of the snippet.
private void printReport()
     Frame tempFrame = new Frame(getName());
     PrintJob printerJob = Toolkit.getDefaultToolkit().getPrintJob(tempFrame, "Liesltext", null);
     Graphics g = printerJob.getGraphics();
                //I wrote the method below for calculations
     printBasics(g);
     g.dispose();
     printerJob.end();
}This alone wont print it you have to do all the calculations in the printBasics method. And as I said I wrote this from scratch and all I did was research first the tutorial and the white papers

Thank's

Lavanya,
This question relates to shell scripting and in IMO it is not an oracle question.
I have made some initial assumptions before my proposed solution.
PLEASE note that this is untested, but can just guide you as a template for solving your problem.
Assuming that you have properly set up the control file and mapped each and every table in it as per the file information which you have..
Assuming the text file to be in the format of : ------ (as suggested by other posters earlier, this file holds instructions about the file and table mapping which shall be used by your sqlldr process.)
tmp.txt:
text_file_1-------------should goes to----customer_info_table
text_file_2------------should goes to------customer_address_table
text_file_3-----------should goes to-------customer_order_table
while read line
do
SQLLDR CONTROL=`echo $line | sed 's/should goes to/ /g' | sed 's/-//g' | awk -F " " '{print $1}'`.ctl,
LOG=`echo $line | sed 's/should goes to/ /g' | sed 's/-//g' | awk -F " " '{print $1}'`.log,
BAD=`echo $line | sed 's/should goes to/ /g' | sed 's/-//g' | awk -F " " '{print $1}'`.bad,
DATA=`echo $line | sed 's/should goes to/ /g' | sed 's/-//g' | awk -F " " '{print $1}'`.txt
USERID=scott/tiger
done <tmp.txtAll I am trying to run from the above shell script is : -- PLEASE TEST it if it matches your requirement.
SQLLDR CONTROL=text_file_1.ctl, LOG=text_file_1.log, BAD=text_file_1.bad, DATA=text_file_1.txt USERID=scott/tiger
SQLLDR CONTROL=text_file_2.ctl, LOG=text_file_2.log, BAD=text_file_2.bad, DATA=text_file_2.txt USERID=scott/tiger
SQLLDR CONTROL=text_file_3.ctl, LOG=text_file_3.log, BAD=text_file_3.bad, DATA=text_file_3.txt USERID=scott/tigerRepeating my assumptions, I assume you have all those files required for SQLLDR process to run (ctl file, data file...)

How to download a text file from the server

hi everyone,
can anyone tell me how to download and read a text file from the server and saved in into resource folder.
with regards
pallavi

its really easy
To read from server, use something like:
HttpConnection connector = null;
InputStream inp_stream = null;
OutputStream out_stream = null;
void CloseConnection()
     if(inp_stream!=null)inp_stream.close();
     inp_stream=null;
     if(out_stream!=null)out_stream.close();
     out_stream=null;
     connector.close();
     connector = null;
public void getResponse(String URL,String params)
try
     if(connector==null)connector = (HttpConnection)Connector.open(URL);//URL of your text file / php script
     connector.setRequestMethod(HttpConnection.POST);
     connector.setRequestProperty("User-Agent","Profile/MIDP-2.0 Configuration/CLDC-1.1");
     connector.setRequestProperty("content-type", "application/x-www-form-urlencoded");
     //connector.setRequestProperty("charset","windows-1251");
     //*** If you need to send ("arg1=value&arg2=value") arguments to script use this:
     out_stream = connector.openOutputStream();
     byte postmsg[] = params.getBytes();
     out_stream.write(postmsg);
     int rc = connector.getResponseCode();//in any case here connection will be opened & closed
     if (rc != HttpConnection.HTTP_OK)
          CloseConnection();
          throw new IOException("HTTP response code: " + rc);
     inp_stream = connector.openInputStream();
     int pack_len = inp_stream.available();
     byte answ[]=new byte[pack_len];
     inp_stream.read(answ);
     CloseConnection();
     ProcAnswer(answ);//process received data
catch(Exception ex)
     System.err.println("ERROR IN getResponse(): "+ex);
} And you can read from resource file like
public void loadFile(String filename)
    DataInputStream dis = new DataInputStream(getClass().getResourceAsStream("/"+filename));
    String str="";
    try
         while (true)
            ch = dis.read();//read character
            if(ch=='\r')continue;//if file made in windows
            if(ch=='\n' || ch==-1)//end of line or end of file
                if(str.length()==0)continue;//if empty line
                //do some thing with "str"
                if(ch==-1)break;//it was last line
                str="";//next line
                continue;
             str+=(char)ch;
       dis.close();
   catch (Exception e)
       System.err.println("ERROR in loadFile() " + e);
}Welcome! =)

How to retrieve data (xml file) using jsp

I am a newbie to xml. I have decided to store my information in the xml file. may I know how can I retrieve my information from the xml file?
Thanx in advance.

I am a newbie to xml. I have decided to store my
information in the xml file. may I know how can I
retrieve my information from the xml file?
Thanx in advance.You can get the information from the XML file using one of the parsers available, such as Xerces http://xml.apache.org, and JDOM as an API.
Using this you have the option of having a SAXParser or a DOMParser.
SAX (Simple API for XML) is an event based parser, so if you know the XML structure, and need to find a certain element, you can just look for the element name,and retrieve the value of the element, it's attributes and its children.
DOM(Document Object Model)represents the XML as a tree, but uses more resources as it stores the entire tree in memory. But it is good in that you can traverse the whole tree.
JDOM would be a good idea too. If you download this, you can use it's API, which is very good, that will use the parser on your system (Xerces). I would definately recommend JDOM.

Download a text file from JSP (Urgent Please!)

Hi,
I have a issue with this JSP, I need to download a txt file from my webserver to the pc client, the page shows the dialg box but appear the filename (list.jsp) of my jsp instead of the txt file.
If I click the save buton save the list.jsp page; if I click in the open buton, then appear again the dialg box and now appear the url (download.jsp?filename=...) and if I click in the save button now I can save my txt file in the local pc.!!!!
Any ideas ??
list.jsp --> is the jsp from the download.jsp is run.
download.jsp
<%@ page import="java.io.*,javax.servlet.*,java.util.* "%><% String filename = request.getParameter("filename");
response.setContentType("application/download");
String value = "attachment; filename=\"" + filename + "\";" ;
response.setHeader("Content-Disposition",value);
int iRead;
FileInputStream stream = null;
try {
File f = new File("C://test//" + filename);
stream = new FileInputStream(f);
while ((iRead = stream.read()) != -1) {
out.write(iRead);
out.flush();
finally {
if (stream != null) {
stream.close();
%>

Maybe try no quotes around the content disposition header?
Also, I'm not sure that application/download would be the best content type, maybe "application/octet-stream" instead. You should also probably explicitly set the Content-Length header to the file size.
