Question

I want to create a request for JSON-RPC with three parameters – String, Integer and my own object. Request should look like this:

{"method":"MyMethod", "params":["text", 123, {"name": "any text", "num": 15}], "id":1}

Ideally, I would like to create an AutoBean like this (but it does not work):

interface JsonRpcRequest {  

    String getJsonrpc();
    void setJsonrpc(String value);

    String getMethod();
    void setMethod(String value);

    List<Object> getParams(); // ERROR: Type Object may not be used
    void setParams(List<Object> params); // ERROR: Type Object may not be used

} 

interface JsonRpcRequestFactory extends AutoBeanFactory {

    AutoBean<JsonRpcRequest> jsonRpcRequest();

}

The problem is that the AutoBean framework does not allows the use of List<Object> inside interface.

Is there another way to create a list/array of elements of different based and non-based types?

No, you simply can’t. AutoBean requires everything to be statically typed: no polymorphism, and no mixed-typed lists of maps.

You might be interested by RequestFactory’s built-in support for JSON-RPC though.
