How to trigger an update in DBAT connector?

Question

Hello,
I have set up the DBAT connector so that "Create User" task would call the create user groovy script, which calls the stored procedure to insert records into the parent and child tables.  This works fine.
I also set up the connector so that "Delete User" task would call the delete user groovy script, which calls the stored procedure to delete records in the parent and child tables.  This also works fine.
I have only 1 use case left which is the update of the child table.
I have a field called Reporter ID in the USR form.  I created a Change Reporter ID process task in DBAT process definition (added this into the lookup.USR_PROCESS_TRIGGERS).  This called an adapter task that just returned a response code of SUCCESS.  I want to attach a process task to this Change Reporter ID so that "somehow" it would call my "update user" groovy script, which calls the stored procedure to delete records from the child table and re-insert new records into the child table.
How can I achieve this?  I don't want to update anything in the parent process form or child process form.  I just want to call my update user stored procedure.
Thanks

Thank you for your response.
I created the below java code and created a process task in DBAT User process form to call this code on "Change Reporter ID" event.
import groovy.lang.GroovyClassLoader;
import groovy.lang.GroovyObject;
import groovy.lang.GroovyShell;
//import groovy.lang.Binding;
import java.io.File;
import java.util.logging.Logger;
public class MyDBATUpdateUser extends GroovyShell {
    private String METHOD_NAME = "DEBUG: MyDBATUpdateUser: ";
    public String MyDBATUpdateUser() {
        String result = "";
        try {
            ClassLoader parent = MyDBATUpdateUser.class.getClassLoader();
              GroovyClassLoader loader = new GroovyClassLoader(parent);
            Class groovyClass =
                loader.parseClass(new File("/home/iam_dev/dbat/scripts/my_dbat_update_user.groovy"));
            logger.warning(METHOD_NAME +
                           "Passed groovy file name");
            GroovyObject groovyObject =
                (GroovyObject)groovyClass.newInstance();
            Object[] args = { };
            logger.warning(METHOD_NAME + "Defined args");
            groovyObject.invokeMethod("run", args);
            logger.warning(METHOD_NAME + "Success");
            return "SUCCESS";
        } catch (Exception e) {
            logger.warning("MYPROJECT ERROR: " + METHOD_NAME +
                           "Error encountered in main");
            e.printStackTrace();
            return "REJECT";
It seemed the above java code died at the line of code: groovyObject.invokeMethod("run", args);
my groovy script looks like this:
import java.util.*;
CallableStatement st = null;
def id = attributes['__NAME__']?.value?.get(0);
try {
st = conn.prepareCall("{call MY_PROC_ADD_CHILD_GROUP(?)}");
st.setString(1, id);
st.executeUpdate();
} finally {
if (st != null)
st.close();
trace.error("Called MY_PROC_ADD_CHILD_GROUP [${id}]");
return new Uid(id);
Thanks for letting me know what's wrong with the above code.
