This is my webservice code....




/**
*/

package stocks.soapservices;

import java.util.Hashtable;

import stocks.util.StockQuote;

/**
* StockQuoteService.java
*
* SOAP based Stock Quote Services include : - addQuote() - to add a new stock
* quote - getQuote() - to get the current price of a given stock symbol -
* getAllQuotes() - to get all the quotes in the database
*
* for demo purposes, this service contains an 'init' method to load some same
* stock quotes.
*
*/

public final class StockQuoteService {
public final Hashtable stockData;

/**
* Constructor
*/

public StockQuoteService() {
stockData = new Hashtable();
init(); // Usually initializes JDBC Access in a real-world situation
}

/**
* Add/Update a stock quote
*
* @param StockQuote
*/

@SuppressWarnings("unchecked")
public boolean addQuote(StockQuote stockQuote) {
if (stockQuote != null) {
stockData.put(stockQuote.getSymbol().trim(), stockQuote);
ServerNotificationHandler.getInstance().dataChanged();
return true;
}
return false;
}

public boolean deleteQuote(String symbol) {
if (symbol != null) {
stockData.remove(symbol);
ServerNotificationHandler.getInstance().dataChanged();
return true;
}
return false;
}

/**
* Get the StockQuote for a specified Stock Symbol
*
* @param String
* @return StockQuote
*/

public StockQuote getQuote(String symbol) {
return (StockQuote) stockData.get(symbol);
}

/**
* Get all the StockQuotes from the database.
*
* @return Hashtable
*/

public Hashtable getAllQuotes() {
return stockData;
}

/**
* Initialize temporary data for demo purpose only
*
*/

private void init() {
stockData.put("CSCO", new StockQuote("CSCO", "Cisco", 19.62));
stockData.put("INTC", new StockQuote("INTC", "Intel", 33.81));
stockData.put("IBM", new StockQuote("IBM", "IBM", 122.20));
stockData.put("MSFT", new StockQuote("MSFT", "Microsoft", 69.27));
stockData.put("ORCL", new StockQuote("ORCL", "Oracle", 15.05));
stockData.put("SUNW", new StockQuote("SUNW", "Sun", 12.58));
}

}



------------------------------


The problem i am facing now is i am not able to get the hashtable from the getAllQuotes method...



this is the response for the getAllQuotes method

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns:getAllQuotesResponse xmlns:ns="http://soapservices.stocks">
<ns:return xsi:type="axis2ns1:anyType" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ax23="http://util.stocks/xsd">
<empty xmlns="http://www.w3.org/2001/XMLSchema">false</empty>
</ns:return>
</ns:getAllQuotesResponse>
</soapenv:Body>
</soapenv:Envelope>
