Object types return hex characters with xsql:query

Question

How do I use xsql servlet to return an object which contains street address etc. as a character string and not a hexadecimal string. If I use the following ddl and implement the following xsql, I get the following results.
CREATE TYPE address_objtyp AS object
(street VARCHAR(30),city VARCHAR(30),state VARCHAR(2));
CREATE SEQUENCE employees_seq START WITH 105 INCREMENT BY 1;
CREATE TABLE employees(
id NUMBER(4) CONSTRAINT emp_pkId PRIMARY KEY,
first_name VARCHAR(30),
last_name VARCHAR(30),
address address_objtyp);
INSERT INTO employees VALUES (
103, 'Fred', 'Couples',
address_objtyp('9201 Park St', 'Alexandria', 'VA'));
<?xml version="1.0"?>
<xsql:query null-indicator="yes" connection="demo"
allow-client-style="yes" xmlns:xsql="urn:oracle-xsql">
select * from employees
</xsql:query>
<?xml version="1.0" ?>
- <ROWSET xsql-timing="20">
- <ROW num="1">
<ID>103</ID>
<FIRST_NAME>Fred</FIRST_NAME>
<LAST_NAME>Couples</LAST_NAME>
- <ADDRESS>
<STREET>0x39323031205061726B205374</STREET>
<CITY>0x416C6578616E64726961</CITY>
<STATE>0x5641</STATE>
</ADDRESS>
</ROW>
</ROWSET>
I'm using the most recent jdbc thin driver (ojdbc14.jar) that is for jdk 1.4. I'm using a 9.0.1 db, and I'm using xdk for java 9.2.0.3. So I thought that the thin driver is not capable, so I tried the oci driver, and find another set of problems.
I get the following error:
Oracle XDK Java 9.2.0.3.0 Production
XSQL-017: Unexpected Error Occurred
java.lang.UnsatisfiedLinkError: no ocijdbc8 in java.library.path
Now why does XDK insist to look for ocijdbc8 if I only have ocijdbc9.dll installed on my client? The config file only allows oci8 in the dburl specification, which is probably why XDK insists to look for ocijdbc8, but I CANNOT specify oci9, which would make sense to me, although it's most likely not a valid specification.
<connection name="9ic">
<username>scott</username>
<password>tiger</password>
<dburl>jdbc:oracle:oci8:@</dburl>
<driver>oracle.jdbc.OracleDriver</driver>
<autocommit>true</autocommit>
</connection>
And lastly documentation that comes with ojdbc14.jar indicates to now use a different specification for the jdbc thin driver. Instead of the usual
<dburl>jdbc:oracle:thin:@host:port:sid</dburl>
it recommends
<dburl>jdbc:oracle:thin:@//host:port/service</dburl>
however this does not work with XDK 9.2.0.3. Any ideas why not?
By the way if I use SQL*Plus and select * from employees, I get the desired result in SQL*Plus, which suggests to me that I DO need the oci driver for XSQL Servlet. So how do I get XSQL Servlet 9.2.0.3 to use the oci 9 driver. I know how to set wrapper.path in the servlet config file to find ocijdbc9.dll, but XSQL Servlet still wants to find ocijdbc8.
I sense that there is a bug hidden somewhere in the XDK kit.
