UDF question.

Question

Hello,
I have following code in UDF that pads string to 9 characters long (fills with leading spaces) and adds to SQL query. Please look at the following code.
public void getStatement(String[] companyId,ResultList result,Container container){
int len = companyId.length;
StringBuffer ids = new StringBuffer();
   int totalLen = 9;
for (int i=0; i<len;i++)
<b>     int len2 = companyId<i>.length();
     StringBuffer paddedId = new StringBuffer(totalLen);
     int pad = totalLen-len2;
     while(pad>0)
         paddedId.append(" ");
         pad--;
     paddedId.append(companyId<i>);</b>   
     ids.append("'"paddedId.toString()"'");
     if(i != len-1)
       ids.append(",");
result.addValue("selectemp_no, emp_name from employee where emp_no in ("ids.toString()")");
I tested above function using test mapping. The following is the output.
16:57:44 Start of test
Document start
Start tag [ns1:MT_Cma_Customer_Select_Request]
Add raw attribute [ xmlns:ns1="http://freemanco.com/xi/Get_Customer"]
Start tag [Statement]
Start tag [LawsonCustomer]
Add attribute: [action]=[SQL_QUERY]
Start tag [access]
Put value [<b>select emp_no, emp_name from employee where emp_no in(' 45632')</b>
Close tag [access]
Close tag [LawsonCustomer]
Close tag [Statement]
Close tag [ns1:MT_Cma_Customer_Select_Request]
Document end
Executed successfully
16:57:44 End of test
As you see the bold code is used to pad leading spaces and after test the I do not see leading spaces in the select statement.
Can some tell me what am I doing wrong?.
Thank you for the help.

Balaji,
I'm sorry u want Leading spaces right? My program will give u Trailing spaces. So change one line of code.
Remove sb.append(test[m]); before the 2'nd for loop and add the same in the end of seconf for loop. So now ur code b'come
StringBuffer sb= new StringBuffer();
sb.append("Select * from employee_tbl where employee_id in (");
                                int len;
          for(int m=0;m<test.length;m++)
               len= test[m].length();
               for(int k=len;k<=9;k++)
                    if(!(len==9))
                    sb.append(" ");
                          sb.append(test[m]);
               if(m==test.length-1)
                    sb.append(");");
               else
                    sb.append(",");
          result.addValue(""+sb.toString()+"");
