Please help on GWT JAVA Generics with ValueProxy
I have the following Domain class
public class GenericTreeNode<T> implements java.io.Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private T data;
private List<GenericTreeNode<T>> children;
private GenericTreeNode<T> parent;
public GenericTreeNode() {
super();
children = new ArrayList<GenericTreeNode<T>>();
}
public GenericTreeNode( T data ) {
this();
setData( data );
}
public GenericTreeNode<T> getParent() {
return this.parent;
}
public List<GenericTreeNode<T>> getChildren() {
return this.children;
}
public void removeChildAt( int index ) throws
IndexOutOfBoundsException {
children.remove( index );
}
public GenericTreeNode<T> getChildAt( int index ) throws
IndexOutOfBoundsException {
return children.get( index );
}
public T getData() {
return this.data;
}
public void setData( T data ) {
this.data = data;
}
public String toString() {
return getData().toString();
}
@Override
public boolean equals( Object obj ) {
if ( this == obj ) {
return true;
}
if ( obj == null ) {
return false;
}
if ( getClass() != obj.getClass() ) {
return false;
}
GenericTreeNode<?> other = (GenericTreeNode<?>) obj;
if ( data == null ) {
if ( other.data != null ) {
return false;
}
} else if ( !data.equals( other.data ) ) {
return false;
}
return true;
}
/
}
then I created the following Client Proxies and Request Factory.
import com.google.web.bindery.requestfactory.shared.ProxyForName;
import com.google.web.bindery.requestfactory.shared.ValueProxy;
@ProxyForName( value = "com.vo.Account" )
public interface AccountProxy extends ValueProxy {
public Integer getPfId();
public void setPfId( Integer pfId );
public Integer getPfParentId();
public void setPfParentId( Integer pfParentId );
public Integer getPfRootId();
public void setPfRootId( Integer pfRootId );
public String getName();
public void setName( String name );
}
@ProxyForName( value = "com.vo.GenericTreeNode<Account>" )
public interface AccountNodeProxy<AccountProxy> extends ValueProxy{
List<AccountNodeProxy<AccountProxy>> getChildren();
AccountProxy getData();
}
@ServiceName( value = "com.server.DesktopService", locator =
"com.server.locator.SpringServiceLocator" )
public interface DesktopRequest extends RequestContext {
abstract Request<List<AccountProxy>> getAccounts( Integer realm,
List<Integer> relations );
abstract Request<List<AccountNodeProxy<AccountProxy>>>
getAccountsNodes( Integer realm, List<Integer> relations );
abstract Request<List<AccountProxy>> getAccounts( String userId,
List<Integer> realms );
abstract Request<List<ApplicationProxy>> getApplications();
abstract Request<List<AttributeDefProxy>> getAttributeDefs( String
attributeName );
}
But I still get the message below on Compiling , where am I doing
wrong.
warning: Cannot fully validate proxy since type
com.vo.GenericTreeNode<AccountProxy> is not available
Add @SuppressWarnings("requestfactory") to dismiss.
error: The type AccountProxy cannot be used here
warning: Cannot validate this method because the domain mapping for
the return
type
(com.client.proxy.AccountNodeProxy<com.client.proxy.AccountProxy>)
could not be resolved to a domain type
Add @SuppressWarnings("requestfactory") to dismiss.
error: Could not load domain mapping for context DesktopRequest.
Check that both the shared interfaces and server domain types are on
the classpa
th.
