I have a class like 

Class Function {

public int functionId;
public Type functionId;
public String functionName


public void static main ()
                Function fc= new Function();        

        Type tmp = new Integer(100).getClass();
        Gson gson = new GsonBuilder.create();
        System.out.println(gson.togson(fc) );

I am getting {} ie null for functionType Filed.
What is the issue here ? am I missing something

Please post coding questions like this on our Google Group 
(!forum/google-gson) instead of creating bug 

Not sure if your example is correct. Here are a few suggestions:
new GsonBuilder().create() is same as new Gson()

You are not using Type tmp anywhere. 
In any case, you can get it simply as: Integer.class or int.class

gson.toJson() should print all the fields of Function. Please post complete 
working code on Google group and someone will be able to help you better.

Serializing types is actually somewhat of a security problem, so we don't want 
to support it by default. A malicious .json file could cause your application 
to load classes that it wouldn't otherwise; depending on your class path 
loading certain classes could DoS your application.

But it's quite straightforward to write a type adapter to support this in your 
own app.
