Hi,
I guess you could use javascript on the client side for this.

Hi,
You can use the javamail api for this. You'll also need the JAF API.
You can get the javamail API and java activation framework (JAF) API from the sun site.
Check out the code below, you can adapt it to your needs:
import java.util.*; import com.sun.mail.smtp.*; import javax.mail.*; import javax.mail.internet.*; public class testMail2 { public static void main(String[] args) { String host = "smtp.mail.yahoo.com" ; String username ="xyz"; // your username String fromname = "xyz@yahoo.com" ;//email id String password="xyzpasswd" ;//your password String protocol = "smtp"; String to_addr ="abc@domain.com"; try { Properties props = System.getProperties(); props.put("mail.smtp.host", host); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.from", fromname); Session s = Session.getDefaultInstance(props, null); s.setDebug(true); MimeMessage message = new MimeMessage(s); InternetAddress from = new InternetAddress(fromname); message.setFrom(from); InternetAddress to = new InternetAddress(to_addr); message.addRecipient(Message.RecipientType.TO, to); message.setSubject("Test from JavaMail."); message.setText("Hello from JavaMail!"); message.saveChanges(); Transport transport = s.getTransport(protocol); transport.connect(host, username, password); transport.sendMessage(message, message.getAllRecipients()); transport.close(); } catch(Exception e){ System.out.println(e);} } }

Hi,
1. From account should be a valid account on the yahoo server.
2. Yahoo mail server requires authentication, so set the property "mail.smtp.auth" to true.
3. To get debugging info call setDebug(true) on session object.
Hope this helps.

Hi,
Junit is for unit testing of java classes.
Jmeter can be used for testing servlets - unit as well as load testing.

Thanks Thomas paul,
your article was a big help.

Hi,
You can try the following:
File fil = new File(filename);
FileOutputStream fos=null;
if (fil.exists()){
// file is already there so append to it
fos = FileOutputStream(fil,true);
}
else{
fos=new FIleOutputStream(fil);
}

hope this helps,
Lester.

You can try
System.getProperty("user.dir")

hope this helps.

Try -
File f = new File("./webapps/examples/WEB-INF/classes/mytestfile.txt");
//whatever filename
FileWriter fw = new FileWriter(f);
fw.write("test");
fw.close();

Hope this is useful...

You can try using the FilenameFilter, see the code below. Hope it is helpful...
import java.io.*; public class FileFilterTest { public static void main(String []args){ File f = new File("d:\\java"); // directory that has the files File [] flist = f.listFiles(new FilenameFilterTest()); for(int i=0;i<flist.length; i++){ System.out.println(flist[i].getName()); } } } import java.io.*; public class FilenameFilterTest implements FilenameFilter { public boolean accept(File dir,String name) { if (! (name.endsWith(".txt")&& name.startsWith("myfile"))) return false ; int dotpos = name.indexOf("."); if (dotpos <9) return false; int mm=0; int dd=0; int yyyy=0; try{ mm = new Integer(name.substring(dotpos-8,dotpos-6)).intValue(); dd = new Integer(name.substring(dotpos-6,dotpos-4)).intValue(); yyyy = new Integer(name.substring(dotpos-4,dotpos)).intValue(); } catch(Exception nfe){return false;} // add code for checking date validity here return true; } }

The problem appears to be in:
File f1 = s.getStoreName();
fos1 = new FileOutputStream(f1);
f1 actually represents a folder.
ref your code:
storename = new File("mall", sn); storename.mkdirs(); public File getStoreName() throws IOException { return storename; }
Hence exception will be thrown when you try to open an fileoutputstream to it.
hope this solves your problem.

If you are reading the user input from System.in then the problem maybe because System.in.read returns the user entered text+Carriage return + linefeed (in windows, in unix it will have text+ CR). Hence you need to discard these before using the input string for comparison.
check out the example below:
import java.util.*; public class TestIn { public static void main(String [] args){ byte buf[] = new byte[12]; String str=null; int i=0; try { i=System.in.read(buf); } catch(Exception e){e.printStackTrace();} String in = new String(buf,0,i); System.out.println(" length "+in.length() + " "+in); StringTokenizer stk = new StringTokenizer(in,"\n\r",false); while(stk.hasMoreTokens()){ str = stk.nextToken(); } System.out.println(" length after removing CR, LF is "+str.length()+" String entered "+ str); } }
hope this helps...

If TextFileIn is a class defined by you make sure it can be found in one of the folders in your classpath.
Also make sure your classpath includes "." (ie the current folder).
If textFileIn is not in a package, put it in th3e same folder as your main class and then compile.
If TextFileIn is in a package then you need to import it.
You can also check out the following code:
import java.io.*; public class FileTest{ public static void main(String [] args){ int numlines=0; try { FileReader fr = new FileReader(args[0]); LineNumberReader lnr = new LineNumberReader(fr); String line =lnr.readLine(); while (line!=null) { numlines=lnr.getLineNumber(); System.out.println( numlines + " " + line); line = lnr.readLine(); } } catch(Exception e){e.printStackTrace();} System.out.println("total lines "+ numlines); } }
