Return arrary of objects from web service

Question

Hello ALL,
This problem has stumped me for several days.
I have a web service and a jsp client. the jsp client call the web service. the web service function return an array of object of DataBaseRecord type. I use XFire + MyEclipse + Tomcat to develop this project in a Linux box.
the web service WelcomeYou is defined as follows
{noformat}public List<DataBaseRecord> WelcomeYou(String ExampleDoc)
   List<DataBaseRecord> RetrievalResult = new ArrayList<DataBaseRecord>();
  //  Search relevant documents according to 'ExampleDoc' from a database
  //  The search result will be put into a RecordSet object 'rs'
   while(rs.next())
              DataBaseRecord  NewRecord = new DataBaseRecord ();
              NewRecord.RetrievedDocID = rs.getString("RetrievalDocID");
              NewRecord.SimiScore =  Float.valueof(rs.getString("SimiScore"));
              RetrievalResult.add(NewRecord );
// I use the following for loop to see the content of RetrievalResult. I can see that the content is just what I expect. Additionally, the size of RetrievalResult is correct too.
for(DataBaseRecord   databaserecord : RetrievalResult)
     System.out.println(databaserecord.RetrievedDocID + databaserecord.SimiScore);
  return RetrievalResult;{noformat}in a jsp file, the web service WelcomeYou is called
{noformat}List<DataBaseRecord>  Result = new List<DataBaseRecord>();
Result = srvc.WelcomeYou("some text ");
// I use the following for loop to see the contentof Result, but each element of Result is empty. Moreover, the strange thing is that the size of Result is right.
for(DataBaseRecord   databaserecord : Result)
     System.out.println(databaserecord.RetrievedDocID + databaserecord.SimiScore);
{noformat}the class DataBaseRecord is defined as follows
{noformat}public class DataBaseRecord{
    public String RetrievedDocID;
    public float SimiScore;
{noformat}At the very end of the service function body(just before ' return RetrievalResult;'), i check the content of RetrievalResult using a for loop, it is correct.
At the jsp file, immediately after the statement
{noformat}   Result = srvc.WelcomeYou("some text ");
{noformat}
{code}
, i check the content of Result using a for loop, it is incorrect except for the size of Result .
I wonder where I am wrong in the above code.

Can you show the UserProfile.java ? That may have some variables, which are not supported in web services.
