Retrieving data in jsp from bean

Hi,

I have a jsp page called test1.jsp. I am retrieving data from a bean called Ramdomizer.java. The lines in the jsp are as follows:

[/code]

int arr[]=new int[20];

<jsp:useBean id="MyRamdomizer" class="Ramdomizer" scope="session">

<jsp:getProperty name="MyRandomizer" property="arr"/>

</jsp:useBean>

[/code]

But, when I run the jsp page, I get the following errors:

org.apache.jasper.JasperException: Unable to compileclassfor JSP

An error occurred at line: 8 in the jsp file: /test1.jsp

Generated servlet error:

The ramdomizer.java program is as follows:

import java.util.*;

publicclass Ramdomizer{

publicstatic Random rand=new Random(System.currentTimeMillis());

static HashSet hs=new HashSet();

public Ramdomizer(){}

publicint [] getRandoms(int maxNo){

hs.clear();

while (true){

int n = rand.nextInt(maxNo);

hs.add(new Integer(n));

if (hs.size() == maxNo){

break;

}

int [] ret=newint[maxNo];

Iterator it=hs.iterator();

int cnt=0;

while (it.hasNext()){

ret[cnt++]=((Integer)it.next()).intValue();

}

return shuffle(ret);

}

privateint [] shuffle(int [] arr){

for (int i=1; i<arr.length; i++){

int rp = rand.nextInt(20);

int tmp=arr[rp];

arr[rp]=arr[i];

arr[i]=tmp;

}

return arr;

}

/**

* *********** MAIN ***********

publicstaticvoid main(String[] args){

Ramdomizer rd =new Ramdomizer();

int [] rn=rd.getRandoms(20);

showResult(rn);

/*rn=rd.getRandoms(10);

showResult(rn);*/

//getRandomNum(rn);

}

privatestaticvoid showResult(int[] rn){

for (int i=0; i><rn.length; i++){

System.out.println(i+": "+rn[i]);

}

publicint[] getRandomNum(int[] rn){

return rn;

}

So, what am I doing wrong? Someone plz help.

Rgds,
