Can a Stored Procedure be called from a Rule (not using Scripted JDBC Adap)

Question

Hello smart people,
Question: Can a stored procedure be called from a Rule without using the Scripted JDBC Resource Adapter?
What's Desired: The project has very strong sql developers and average at best Java developers. We have been successful at implementing the scripted JDBC Resource Adapter which makes use of Java Bean shells. The custom Java Bean shell contains code that calls a stored procedure. We are cool with that process.
However we would like to be able to set up a Rule that calls a Stored Procedure without jumping thru the Java Bean Shell layer. The Stored Procedures we will be developing will not access the tables in the Waveset database. Instead the Stored Procedures will be accessing custom tables in a custom database. The custom DBase will be housed on the same dBase server as the Waveset database.
Environment: Identity Manager 7.1. Oracle 10i, and Unix OS.
It seems to me that this task is possible, but the posts in this forum make it sound like perhaps it is not.
Do any of you smart people agree that it should be possible or better yet has anyone implemented such an approach?
Thanks.

We did this by putting all of the JDBC calls into a Java class, then instantiated that class and called the methods from within a rule. An example of a rule we used is this:
<Rule authType='UserMembersRule' name='List UserType'>
  <block>
    <defvar name='adapter'>
      <new class='com.waveset.adapter.ScriptedJdbcResourceAdapter'/>
    </defvar>
    <invoke name='setResource'>
      <ref>adapter</ref>
      <invoke name='getObject' class='com.waveset.ui.FormUtil'>
        <ref>context</ref>
        <s>Resource</s>
        <s>Banner</s>
      </invoke>
    </invoke>
    <defvar name='jdbcHelper'>
      <new class='edu.bates.JDBCHelper'>
        <invoke name='getConnection'>
          <ref>adapter</ref>
        </invoke>
      </new>
    </defvar>
    <defvar name='userList'>
      <new class='java.util.ArrayList'/>
    </defvar>
    <invoke name='addQueryToList'>
      <ref>jdbcHelper</ref>
      <s>SQL QUERY HERE</s>
      <ref>userList</ref>
    </invoke>
    <ref>userList</ref>
  </block>
  <MemberObjectGroups>
    <ObjectRef type='ObjectGroup' id='#ID#Top' name='Top'/>
  </MemberObjectGroups>
</Rule>
