Problem in copy a string to a message parameter

Question

Hi all,
I have a problem in copy a static string into a message as its parameter.
I use the default function in creating the copy rules...
<copy xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/">
     <from expression="string(WS1-PSC4-KUY2)">
     </from>
     <to variable="geo_in" part="parameters" query="/ns0:GetLocationByIP/ns0:LicenseKey"/>
</copy>
as the string is a liscence key to use this web service.
However, the string is not copied to anywhere of the outgoing message.
If I use the default type 'literal' and copy to the variable parameter,
it looks like this...
<copy xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/">
     <from>
                              WS1-PSC4-KUY2
                    </from>
     <to variable="geo_in" part="parameters" query="/ns0:GetLocationByIP/ns0:LicenseKey"/>
</copy>
it gives me an error...
[bpelc] BPEL source validation failed, the errors are:
[bpelc]
[bpelc] [Error]: Element 'from' must have no character [children], because the types content type is element-only.
[bpelc] [Description]: in line 43 of "C:\eclipse\workspace\ip_locate\ip_locate.bpel", Element 'from' must have no character [children], because the types content type is element-only..
[bpelc] [Potential fix]: .

Could anybody give me a hint on what's going wrong?

This is my actual code
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;
public class TestingDate {
      * @param args
     public static void main(String[] args) {
          // TODO Auto-generated method stub
          String dateFormat="EEEE, MMM d h:mm a";
          Date test=new Date(2007,0,19, 19, 31);
          System.out.println(" original date is "+test);
          String stringResult=DateToString(test,dateFormat);
          System.out.println("Date to string is "+stringResult);
          Date dateResult=stringToDate(stringResult,dateFormat);
          System.out.println(" String to date is "+dateResult);
          String stringResult2=DateToString(dateResult,dateFormat);
          System.out.println(" Date to string  is "+stringResult2);
public static String DateToString(Date test, String dateFormat) {
         String result = null;
         try {
              DateFormat myDateFormat = new SimpleDateFormat(dateFormat);
                 result = myDateFormat.format(test);
                 //System.out.println(" reslut date is "+result);
          } catch (Exception e) {
               System.out.println(" Exception is "+e);
          return result;
public static Date stringToDate(String strDate,String dateFormat1){
     Date result1=null;
     try {
          DateFormat myDateFormat = new SimpleDateFormat(dateFormat1);
          result1=myDateFormat.parse(strDate);
     catch(Exception e){
          System.out.println(" exception is "+e);
     return result1;
}I am facing problem in getting the actual date. Please suggest the solution.
