Well as I understand it GAE is just a servlet container so you have a
varitey of options to pass java 'Objects' back and forth between two
Servlets.
You Could;
Use GWT's RPC code to pass stuff between two Servlets (no examples for
this, you probably need to look at some of the GWT source code to
figure this out.)
Use a custom serlization technique to pass your Objects over CGI
(Common Gateway Interface)
for instance
Student tom = new Student()
tom.setName("tom");
String url = new String();
url = "googleappengine.com/yourServletMapping?
action=recieveStudent&studentName=" + tom.getName();
//sendUrlViaJava read this
http://www.exampledepot.com/egs/java.net/Post.html
Use a SOAP or other xml technique to serialize your object to xml and
then read it in using sax or something in the Servlet.
Use JSON to serialize your Java Object to the Javascript format and
then read it in through the GWT Json api serverside.
Personally I would use GWT's RPC serlization, although it may initally
be more work because there arn't many examples, it will probably be
the least maintenance once you've figured it out.
Good Luck,
Scott
