Open office sdk create xls, doc,ppt files in Java

How to create a xls file using open office sdk? Please give Java example source code. Also needed to create word and power point files. I’m not able to get any examples
Below is the code I tried. It tries to open in Open office App, that I don't want. I want to generate the .ods file in the WebSphere App Server under AIX environment, using Java. I'm using it to generate a report and download it to front end (web app).

why my crawledURL is null?

I am following a tutorial to create a web crawler in java. When I run the code my crawledURL is null. *** Malformed URL :null in a infinite loop.
Can anyone explain to me why is this happening?
Here is the whole code:
import java.util.*;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import java.io.*;
import java.net.*;
public class WebCrawler {
public static Queue<String> Queue = new LinkedList<>();
public static Set<String> marked = new HashSet<>();
public static String regex = "http[s]://(\\w+\\.)*(\\w+)";
public static void bfsAlgorithm(String root) throws IOException {
Queue.add(root);
while (!Queue.isEmpty()) {
String crawledURL = Queue.poll();
System.out.println("\n=== Site crawled : " + crawledURL + "===");
//Limiting to a 100 websites here
if(marked.size() > 100)
return;
boolean ok = false;
URL url = null;
BufferedReader br = null;
while (!ok) {
try {
url = new URL(crawledURL);
br = new BufferedReader(new InputStreamReader(url.openStream()));
ok = true;
} catch (MalformedURLException e) {
System.out.println("*** Malformed URL :" + crawledURL);
crawledURL = Queue.poll();
ok = false;
} catch (IOException ioe) {
System.out.println("*** IOException for URL :" + crawledURL);
crawledURL = Queue.poll();
ok = false;
}
}
StringBuilder sb = new StringBuilder();
while((crawledURL = br.readLine()) != null) {
sb.append(crawledURL);
}
crawledURL = sb.toString();
Pattern pattern = Pattern.compile(regex);
Matcher matcher = pattern.matcher(crawledURL);
while (matcher.find()){
String w = matcher.group();
if (!marked.contains(w)) {
marked.add(w);
System.out.println("Site added for crawling : " + w);
Queue.add(w);
}
}
}
}
public static void showResults() {
System.out.println("\n\nResults :");
System.out.print("Web sites craweled: " + marked.size() + "\n");
for (String s : marked) {
System.out.println("* " + s);
}
}
public static void main(String[] args) {
try {
bfsAlgorithm("http://www.ssaurel.com/blog");
showResults();
} catch (IOException e) {
//TODO Auto-generated catch block
e.printStackTrace();

}

while (!Queue.isEmpty()) {

...
} catch (MalformedURLException e) {

second time you do not check is queue empty

when my worklist containes just one element it works perfectly. But, when the worklist containes more than one element, I get as a result just the last element saved in the worklist file.
please any idea how to fix that?

I thinks your code has got following problems:
Firstly,
output = new FileOutputStream("C:\\properties\\worklist.properties");
is inside for loop
for(DicomObject dcm : result) {
-> the worklist.properties file will be overwritten again and again.
The second,
worklist.setProperty("1",dcm.getString(Tag.PatientName));
worklist.setProperty("2",dcm.getString(Tag.PatientName));
got same property keys (1 and 2) so the value will be overwritten too.
EDIT:
Add sample code:
output = new FileOutputStream("C:\\properties\\worklist.properties");
// For example
int propid = 1;
for(DicomObject dcm : result) {
String key = "patientName" + new Integer(propid++).toString();
worklist.setProperty(key,dcm.getString(Tag.PatientName));
}
worklist.store(output, null);

config,properties file does not update in real time while running service via the browser

i try to implement some rest api for read mails service.
now i have a command that can stop/run the service.
after i run the service for some reason when i update my config file in the runService method into "RUNNING" i still get that the status of the service is "ONHOLD" and i dont undersatnd why. there for the do while loop terminated only after 1 iteration.
there is a delay while we working with files inside the program code?

I don't really understand your problem but, at least, I think that you have a problem inside runService method:
Note:added some comments into the code starting with '<--'
String stat = prop.getProperty("status"); <-- you read the property here
if(stat.equals(status.FINISHED.toString()) || stat.equals(status.ONHOLD.toString()))
{
updateConfigfile(username+".properties","status",status.RUNNING.toString());
do{
i++;
model.addAttribute("msg","inside loop"+" "+"Counter is:"+" "+i+" "+"status is =" +prop.getProperty("status")); <-- status contains FINISHED or ONHOLD! It is the same as using stat variable.
}while(prop.getProperty("status").equals(status.RUNNING.toString())); <--contains FINISHED or ONHOLD! so, always return false
}else{
model.addAttribute("msg","Service is already running");
}
In other words, if you change the file you need to read it again in order to have an updated properties into properties object.
Hope this helps!
I mean this referred to my last comment!
String stat = prop.getProperty("status");
if(stat.equals(status.FINISHED.toString()) || stat.equals(status.ONHOLD.toString()))
{
updateConfigfile(username+".properties","status",status.RUNNING.toString());
prop.setProperty("status",status.RUNNING.toString());
i++;
model.addAttribute("msg","inside loop"+" "+"Counter is:"+" "+i+" "+"status is =" +prop.getProperty("status"));
}else{
model.addAttribute("msg","Service is already running");

Logcat window:
Accepting connections on port 9000
Document Root: D:\
now when i connect to my web server in my log i get
Logcat Update:
07-29 14:42:46.175: D/SntpClient(59): request time failed: java.net.SocketException: Address family not supported by protocol
07-29 14:47:46.195: D/SntpClient(59): request time failed: java.net.SocketException: Address family not supported by protocol

The log says it's accepting connections on port 80, but your server runs on port 9000 - I guess that's the problem.
