Hi,
I'm trying to figure out how RFC context initialization works.
If I'm not mistaken, when I have to use a model, I have to create a model bound node in the context and I have to initialize it by creating the appropriate structures (the java beans that will hold the values) and binding them to the nodes.
//$$begin ZMCTBPM_A_READ_NOTE_SR00(-15072069)
ReadNote_SR00 readNote_SR00Model = new ReadNote_SR00();
com.mycompany.mctciat_rfc.readnot.Zmctbpm_A_Read_Note_Input zmctbpm_A_Read_Note_Input_SR00 = new com.mycompany.mctciat_rfc.readnot.Zmctbpm_A_Read_Note_Input(readNote_SR00Model);
java.util.List<com.mycompany.mctciat_rfc.readnot.Zmctbpm_P11> it_Note_SR00 = new ArrayList<com.mycompany.mctciat_rfc.readnot.Zmctbpm_P11>();
zmctbpm_A_Read_Note_Input_SR00.setIt_Note(it_Note_SR00);
com.mycompany.mctciat_rfc.readnot.Zmctbpm_A_Read_Note_Output output_SR00_1 = new com.mycompany.mctciat_rfc.readnot.Zmctbpm_A_Read_Note_Output(readNote_SR00Model);
java.util.List<com.mycompany.mctciat_rfc.readnot.Zmctbpm_P11> it_Note_SR00_1 = new ArrayList<com.mycompany.mctciat_rfc.readnot.Zmctbpm_P11>();
output_SR00_1.setIt_Note(it_Note_SR00_1);
wdContext.nodeZmctbpm_A_Read_Note_Input_SR00().bind(zmctbpm_A_Read_Note_Input_SR00);
//$$end
This is what is automatically made by applying the Service Controller template: it's the code put in the wdDoInit() method. I always used the Service Controller template to initialize the model nodes.
Now I was looking to a Web Dynpro written by another person and this WD adopts a strange method to initialize the model nodes. This WD uses a model that holds several functions and the context is initialized in this way:
1) An instance of the model structure is created
MctBpm_Ac_Model modlInst = new MctBpm_Ac_Model();
2) An instance of the desidered function's root node bean is created, passing the model instance as an argument
Get_Lista_Coge_In bapiInGetListaCoge = new Get_Lista_Coge_In(modlInst);
3) The instance of the root node bean is bound to the context
wdContext.nodeGetListaCoge_In().bind(bapiInGetListaCoge);
That's it. So I want to know:
1) Are these two different method of initialization equivalent? (i.e. using the Service Controller Template and using the other method?).
2) Why it is necessary to bound model nodes to a java bean/structure and for value nodes it is not?
Thank you.

Hi,
can someone point me at least to some SAP documentation where to find informations about models and RFC initializations in Java?
Thank you,
Pietro

Hi Pietro,
1) Are these two different method of initialization equivalent? (i.e. using the Service Controller Template and using the other method?).
Ans: Yes these two are equivalent
2) Why it is necessary to bound model nodes to a java bean/structure and for value nodes it is not?
Ans: refer this thread which you posted
if you want more on Adaptive RFc model refere this
hope this will helps you.
Thanks & Regards,
Bhargava.
