Passing two values in two different views using view criteria in adf bc

Question

I have two tables. Message and MessageProperties. Message table is connected with itself as same as Employee table of HR. Means a Message can have various child message. MessageProperties contains the message properties. A message can have various properties. I want to show the message only if it has a particular value in MessageProperties,then its properties,its child message. If its child message have the same value in MessageProperties,then it shows that. Likewise it should give me a tree structure with its all properties.
When I am hardcode the value then its shows fine.
SELECT Message.MESSAGE_ID,
Message.MSG_CONTENT_ID,
FROM MESSAGE Message, MESSAGE_PROP MessageProp
WHERE (MessageProp.Message_Id=Message.Message_Id) AND ((MessageProp.Key='From' OR MessageProp.Key='To') AND (MessageProp.value='B'))
But when I use the Bind variable in view criteria then I am not able to achieve this.
1. How to do that in adf bc and how to link message and messageprop with this condition?
2. How to pass two parameters in serviceinterface FIndViewCriteria method i.e. messageId and value so that it will show only that message having that value?

Thanks Timo,
It helps me a little bit.
It only shows me the parent message id and its properties. But it is not showing its child message id and its properties.
Let me explain you step by step what I have done.
1> I have created a view MessageView with two entities i.e Message and MessageProp and include the value attribute of MessageProp in it.
2> I have created the default MessagePropView from MessageProp Entity.
3> In MessageView I have modified the query which you have given.
4> I have created the Bind variables.
5> I have created a view criteria and in that view criteria I have included Message_Id=:Bind_MessageId and Value=:Bind_Value.
6> I have created an association connecting Message.Message_Id and Message.Parent_Id(1 to * cardinality) because a message can be a parent of many messages.
7> I have created a viewlink between Message and MessageProp using Message_Id.
8> I have created a view link between Message and Message using the association which I have created in step 6.
9> I have created the Application Module. In that,my Data Model looks like
---MessagePropView2
---MessageView1
---------MessagePropView1
---------MessageView2
10> Then I have created the service interface. In service interface view instances,I include these two view and select the GetByKey operation from basic operations.
11> From View Criteria find operations I have included the view criteria which I have created in message view in step 5.
12> Then I run the AppModuleServiceImpl.java and select the view criteria operation which I have created in step 11.
13> There I find two bind variables i.e. Bind_MessageId and Bind_Value. I give the values there.
But it checks whether that message Id(Bind_MessageId) which I have given have that value(Bind_Value) or not. If it has then it shows only that message along with its properties but it is not showing me its childs and their properties.
I want to show only those child message who have the MessageProp.value as (Bind_Value).
I hope you understand with the scenario.
I'll be very thankfull to you if you help me to do this.
Rohit.
