This is a excellent tutorial.
I also think it's so difficult to me, but I will try to learn more :)
GTW-RPC can only serialize objects that are emulated or new ones you
create that implement Serializable. There are some solutions to get
other stuff to serialize, but that's probably not what you want. If
you make a Data Transfer Object (DTO) that only contains serializable
fields, you'll be able
Thanks for your help,
I'm trying to read and test some demo. So, I realize something about
GWT-RPC.
Yeah, I will try to make a Data Transfer Object.

also.. please post back here if you succeed!
Am also trying to implement the DTO but not sure how far i can do that :)

I also have some problems when I use JDO in GAE + GWT
[ERROR] Errors in 'file:/I:/Workspace/jdo/src/com/jdo/util/
Employee.java'
[ERROR] Line 2: The import com.google.appengine cannot be
resolved
[ERROR] Line 14: Key cannot be resolved to a type
[ERROR] Line 33: Key cannot be
You'll have to build a DTO to transfer these objects to the client
side, I don't think GWT understands GAE Key objects. See this:

I actually thought of the same.. DTO. But I have no idea how to implement
that..
so going through the DTO documentations over net

Okay, we try to solve it. I haven't understand GWT RPC yet.
I want to use MVP model. But I'm familiar with C# than Java.
Hope everything will be better.
I'm trying to try because this is my last chance.
Thank you.

This is a major PITA with GAE+JPA. You'll likely also need to detach
your entities from the JPA session, which AFAIK is impossible with the
JPA interface - only with the JDO interface.
My advice is throw out JPA and use Objectify. You can use your
entities in GWT as-is (assuming they are
Yeah, I ran into this issue a year ago when I was working with GAE +
GWT-RPC. The client side object cannot have references to any code
not associated with a GWT module, so there are a few options for you
here.
1) create a translator and maintain 2 versions of the class; 1 for the
client(without
again - you shall not have any references inside your translatable
classes to classes from 3rd party! translatable classes are those to
be compiled to javascript and which reside in client and shared
packages. 3rd party classes are those where you dont have sourcecode
from.
consider your Employee
Am not sure this belongs to GWT or GAE or both ...
So here's my problem...
I have one client/Example.java [contains all GWT code] calls a methods on
server/SomeServiceImpl.java [Contains code to talk to dataStore]
Wat server/SomeServiceImpl.java does is Featch data from Employee.Java
Any object referenced in client-side code must be in a client
package. The new version of the GWT plugin for eclipse added a shared
package suffix, but it is added to the gwt.xml as a client side
package.

hi the problem is that gwt does not have source of your Employee
class, since you have put it into the server package, you always have
3 packages to handle (as per default):
client
server
shared
everything under client becomes javascript after compilation and is
not aware of anything contained
okey... thanks alot guys
i ll try to make those changes and will update here
also thx for so quick responses.. am loving it

Modified the Employee.java as below
*public class Employee implements IsSerializable{*
then moved the Employee.java to shared package. [eclipse updated all
references well]
Now when I GWT to compile its saying
Compiling module project.xxx
Validating newly compiled units
