I have few questions on legacy connectivity.Please correct me if my question itself is wrong

In JCA resource adapter it's said that each application server support it.And providers like TIBCO,Webmethod will provide it.
Let's take a scenario where in i have to develop the resource adapter for a legacy application.The question is how to develop this.
Still i should be using same JNI to develop it?Also then how will i support transaction,security,etc.So my question is how is that
Resource Adapter different from normal adapter which i will develop. Or like JDBC Driver Resource Adapter is already available in
with the indvidual vendor and just we need to buy it.

Also there could be another approach of using webservices to access legacy system(since lots of legacy system's technology support webservice)?

Iam adding this to the existing question.My data layer in legacy system.If i implement non-java implementation in data layer and expose this layer using corba.Now i use EJB/Corba interface to access this.

Data layer

Entity Beans-->CORBA-->Legacy system

Now will my Entity Beans support transaction,security,database pooling,etc?Or i need to have my non-java implementation of legacy system need to take care of this.
I agree. Here's the link:
