How to use search feature in my JSP?

Question

Hi all,
In my struts application, there is one Jsp page which receives some keyword and based on that keyword it searches the local file system(all diskslike C:\,D:\,E:\.....). how to implement this feature and should display only the latest 10 records. How to implement this.Help me with step-by-step procedure/code help is highly appreciated.
Thanks a lot

Answer 1

Are you searching by the content of a file, or by the name of the file? If you're searching by content..it seems like a search on all the disks will take a very long time.
Here's some rough code:
ArrayList<File> list = new ArrayList();
   File startdir =new File("C:\\");
   recurseFiles(startdir, keyword, list);
   public static final int MAXSIZE = 10;
  private void recurseFiles(File currfile, String keyword, ArrayList<File> list){
       if (currfile.isDirectory()){
             File[] fileset = currfile.listFiles();
             for (int i =0; i<fileset.length; i ++){
                     recurseFiles(fileset, keyword, list);
}else{
try{
boolean found=false;
BufferedReader testread = new BufferedReader(new InputStreamReader(new FileInputStream(currfile)));
while (testread.ready() && !found){
String currline = testread.readLine();
if (currline.indexOf(keyword)!=-1) found = true;
testread.close();
if (found){
int loc = 0;
//most recently modified files are at the end.
while (list.size() > loc && list.get(loc).lastModified() <currfile.lastModified()
loc++;
list.add(loc, currfile);
if (list.size() > MAXSIZE) list.remove(0);
That code should work, I think. I'm a little skeptical of the while loop--can someone verify that?
