Hi ,
Moitra and Thomas
Thanks for your reply.. !!
Anyways i got a solution..
*use this code in the servlet* ---
- get the list of products (productList) and use it in the servlet:
- This is JSON format to form a array of objects
// Open the <script> tag
writer.append("<script type=\"text/javascript\">");
writer.append("var product=");
writer.append("{productList: '[");
Iterator<Product> iter = productList.iterator();
while (iter.hasNext()) {
Product product= iter.next();
writer.append("{productName: \"" + Product .getProductName() +
"\", id: " + Product .getId() +
", productDetails: \"" + Product .getProductDetails() +
.................................
.................................
"\"}");
if (iter.hasNext()) {
writer.append(",");
}
}
// End the <script> tag
writer.append("]'}; </script>");
*use this code in the GWT onModule *---
- call the above servlet on onModule
Dictionary product= Dictionary.getDictionary("product");
String productListStr = product.get("productList").toString();
JSONArray productJSONArray = JSONParser.parse(productListStr
).isArray();
List<Product> ProductList = new ArrayList<Product>();
for (int i = 0; i < productJSONArray .size(); i++) {
JSONObject productJSONObject = (JSONObject)productJSONArray
.get(i);
Product product= new Product();
JSONString productNameJSONString = productJSONObject
.get("productName").isString();
product.setProductName(productNameJSONString .stringValue());
product.setId(Long.valueOf(productJSONObject
.get("id").toString()));
.........................
.........................
ProductList .add(product);
}
finally we will get a list of objects. i.e, ProductList .
Guys its really cool concept .. !! enjoy it !! :-)
