Formatting Elements from a Set
Hi Guys,
I have in my jsp the following code;
<core:forEach var="s" items="${Sandwiches}">
<tr bgcolor="beige">
<td><center>null</td>
<td><core:out value="${s.bread}"/></td>
<td><core:out value="${s.spread}"/></td>
<td><core:out value="${s.baseFillings}"/></td>
<td><core:out value="${s.extraFillings}"/></td>
<td><core:out value="${s.seasonings}"/></center></td>
The values bread, spread, etc, are elements of a set. They are output on the jsp page as;
[Tomato, Mixed Salad, Sliced Onion]
and
[Ham, Chedder Cheese, ]
However I want to format the output and get rid of the brackets. Is this possible?

The relevant code is pretty large and I am also using the spring MVC framework. In short. a parses is used to read each individual word in a text file and store it in the sets bread, spread, etc. These are then passed on to the view and then displayed on the webpage. The following code is used to read the text file;
public Set parse(File textFile) {
Set sandwiches = new HashSet();
try {
//Initializing and declaring the scanner s and getting it to read the text file
Scanner s = new Scanner(new BufferedReader(new FileReader(textFile)));
// s.useDelimiter(System.getProperty("line.separator"));
s.useDelimiter("\r");
long cnt = 0;
while (s.hasNext())//while there are elements to read in s
//each element constitutes as a line
{
//give a String var the value of the next element in the scanner
String line = s.next();
log.debug(line);
//initiate an object of type Sandwich and give it the value returned by calling
//the parseLine Method. Each line read by scanner s is passed into the method
Sandwich sw = parseLine(line, ++cnt);
//sw now references the object of type sandwich s
//add this to the set sandwiches
sandwiches.add(sw);
}
s.close();
} catch (FileNotFoundException e) {
System.out.println("cannot find the file");
// ignore for now
}
return sandwiches;
}
private Sandwich parseLine(String line, long counter) {
//declare a new scanner and pass it the line
Scanner lineScanner = new Scanner(line);
lineScanner.useDelimiter("#");
//create a new object of the type sandwich
Sandwich s = new Sandwich();
//use this object to call and set the filling elements
s.setBread(lineScanner.next());
s.setSpread(lineScanner.next());
for(int i = 0; i<13; i++) {
String var1 = lineScanner.next();
if (!var1.equals("null")) {
s.addBaseFillings(var1);
}
}
for(int i = 0; i<12; i++) {
String var1 = lineScanner.next();
if (!var1.equals("null")) {
s.addExtraFilling(var1);
}
}
for(int i = 0; i<8; i++) {
String var1 = lineScanner.next();
if (!var1.equals("null")) {
s.addSeasonings(var1);
}
}
s.setId(counter);
//return the sandwich object s
return s;
}
This is called by another class which is also used to pass this info to the web page. Is there anything in JSTL I can use to format the elements in the set or the set itself?
