Hello everybody,
I need your help. I use Talend ESB and I want to make java beans to cut
file.
For example, I have this flat file:
11886 1855 0000004309000
11886 1855 0000057370000
11886 1856 0000057374001
11886 1856 0000057375000
In my example I want 2 files (messages), a filter of "1855" and "1856" (It's
the number of orders).
First file:
11886 1855 0000004309000
11886 1855 0000057370000[/CODE]
Second file:
11886 1856 0000057374001
11886 1856 0000057375000[/CODE]
But I don't know the number of orders per file (depending on the file).
If i have three orders (three lines each) in my original file ==> I want
three files with the 3 lines of each order.
If i have four orders in my original file ==> I want four files.
If i have five orders in my original file ==> I want five files.
and so on .......................
This is my start but it return nothing:
package beans;

import java.io.BufferedWriter;
import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

}

InputStream content, String endpoint, Map<String, Object> headers){

InputStreamReader(content));
String line;
Set<String> order=new TreeSet<String>();
try {
String lineId = null;
while((line = br.readLine()) != null){
lineId = line.substring(NUMERO_SITE_START_POSITION,
NUMERO_SITE_END_POSITION);
order.add(lineId);
}
for(int i=0;i<order.size();i++){
String key = "file" + i;
File F = new File(key);
Iterator it = order.iterator();
FileWriter fw = new FileWriter(F.getAbsoluteFile());
BufferedWriter bw = new BufferedWriter(fw);
while((line = br.readLine()) != null){
while(it.hasNext()){
lineId =
line.substring(NUMERO_SITE_START_POSITION, NUMERO_SITE_END_POSITION);
if (lineId.equals(it.next())) {
bw.write(line);
}
}
}
}
} catch (IOException e) {
e.printStackTrace();
}
finally{
try {
if(br != null)br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
can you help me please ?
Thank you in advance.
