Problem in passing values from AS to Java

Question

Hi,
I am using Remote Object(Flex 3) for passing the data
between java and flex. I am using the BlazeDS as the bridge. I have
to pass an array collection containing value objects to the java
method. I have created the value object in both the client side(AS)
and server side (java) and registered my AS value object using
[RemoteClass(alias="class name")]. Now the problem is the
array collection is goinhg to the back end but when i try to get
the values in the value objects using the corresponding getters, i
am getting null values. Can some one suggest me the solution.
Following is my AS value object
package ascript
[RemoteClass(alias="com.category.dao.CatgVO")]
public class CatgVO
private var catg_id:String;
private var parent_catg_id:String;
private var catg_name:String;
private var catg_desc:String;
private var created_by:String;
private var created_date:String;
private var catg_status:String;
private var blooper:String;
private var catg_modifieddate:String;
private var catg_modifieduserid:String;
* @return the catg_id
public function getCatg_id():String {
return catg_id;
* @param catg_id the catg_id to set
public function setCatg_id(catg_id:String):void {
this.catg_id = catg_id;
* @return the parent_catg_id
public function getParent_catg_id():String {
return parent_catg_id;
* @param parent_catg_id the parent_catg_id to set
public function setParent_catg_id(parent_catg_id:String):void
this.parent_catg_id = parent_catg_id;

public function getCatg_name():String {
return catg_name;
* @param catg_name the catg_name to set
public function setCatg_name(catg_name:String):void {
this.catg_name = catg_name;
* @return the catg_desc

return catg_desc;
* @param catg_desc the catg_desc to set

public function getCreated_date():String {
return created_date;
* @param created_date the created_date to set
public function setCreated_date(created_date:String):void {
this.created_date = created_date;
* @return the catg_status

* @param catg_status the catg_status to set
public function setCatg_status(catg_status:String):void {

* @return the blooper
public function getBlooper():String {
return blooper;
* @param blooper the blooper to set
public function setBlooper(blooper:String):void {
this.blooper = blooper;
* @return the catg_modifieddate
public function getCatg_modifieddate():String {

* @param catg_modifieddate the catg_modifieddate to set
public function
setCatg_modifieddate(catg_modifieddate:String):void {
this.catg_modifieddate = catg_modifieddate;
* @return the catg_modifieduserid
public function getCatg_modifieduserid():String{
return catg_modifieduserid;
* @param catg_modifieduserid the catg_modifieduserid to set
public function
setCatg_modifieduserid(catg_modifieduserid:String):void {
this.catg_modifieduserid = catg_modifieduserid;

Hi there. That's a perfectly reasonable question.
Take a look at the section of the Flex documentation with the title "Explicitly mapping ActionScript and Java objects" in the Data Access section of the doc.
http://livedocs.adobe.com/flex/3/html/help.html?content=data_access_4.html
Your BananaVO ActionScript class needs a RemoteClass metadata tag that will tell the AMF deserialization code on the server what Java class to map the object to.
Hope that helps.
