Unable to connect SQL Developer 4.0.2 to Oracle REST Data Services 2.0.7 (Apex Listener)

Question

Background
1. Weblogic 10.3.6.0 running on Oracle Linux 6.5 with Oracle JRockit(R) (build R28.2.3-13-149708-1.6.0_31-20120327-1523-linux-x86_64, compiled mode)
2. Oracle Apex 4.2.1
3. Apex Listener 1.1.3
4. Apex and Apex Listener running on the Weblogic box above
5. SQL Developer 4.0.2 running on Windows 7 64 bit / Java 1.7.0_55
Updated Apex to 4.2.5 via p17966818_425_Generic.zip patchset. Apex environment running fine as do all applications via Listener 1.1.3
Updated Oracle Listener to the latest version of Oracle REST Data Services 2.0.7
Current Status
Apex Applications and RESTful services are running fine.
Problem
Unable to connect SQL Developer 4.0.2 to Oracle REST Data Services 2.0.7
Error message in SQL Developer - Cannot connect to DEV. HTTP/1.1 403 Target service not allowed
Additional Information
Steps followed -
1. The oracle users APEX_LISTENER and APEX_REST_PUBLIC_USER did not exist, so I ran apex_rest_config.sql from the APEX 2.4.1 patchset whilst connected sys as sysdba and provided the same password as APEX_PUBLIC_USER for both users.
2. I also ran
grant insert, delete on APEX_040200.wwv_flow_rt$privilege_groups to APEX_LISTENER;
alter session set current_schema = APEX_LISTENER;
create or replace synonym wwv_flow_rt$privilege_groups for APEX_040200.wwv_flow_rt$privilege_groups;
as per Oracle SQL Developer User's Guide Release 4.0
3. copied ords.war to apex.war
4. java -jar apex.war configdir /u01/app/oracle/admin/apex/devdomain1/
5. java -jar apex.war

8. Deleted the Admin and Manager Roles within the apex application deployment which were part of the Apex Listener 1.1.3 install
9. Deployed the apex.war in weblogic
10. Stopped and started the weblogic server to which apex.war was deployed
11. In SQL Developer, View, RESTful Services. In the RESTful services windows hit connect, Create a new connection,
Connection Name DEV
Username adminlistener
selected http protocol

Server Path /apex
Workspace (blank)
On the Authentication dialog
Username adminlistener
Password passwordsuppliedabove in step 6
Response is a dialog box titled Authentication Failed
message - Cannot connect to DEV. HTTP/1.1 403 Target service not allowed
NOTHING UNUSUAL IN ANY OF THE WEBLOGIC LOG FILES, EXCEPT THAT IT STATES
'Oracle REST Data Services version : 2.0.6.27.18.06' when I've installed 2.0.7.
Any help much appreciated

Answer 1

Further to the above post, I thought I'd simplify my Apex Listener install just to see if I can connect to it via SQL Developer
So downloaded the latest version 2.0.8 and decided to configure and run the Listener on my pc whilst still connecting to the same database.
Operating system : Window 7 Pro 64 bit
Oracle Apex Listener 2.0.8
Java(TM) SE Runtime Environment (build 1.7.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
Went through the configuration as above, once started I tried again to access the listener via SQL Developer. This time I received this output from the listener:
INFO: Error: ORA-02291: integrity constraint (APEX_040200.WWV_FLOW_RT$APPROVALS_SGID_FK) violated - parent key not found, occurred during execution of: [CALL, insert into wwv_flow_rt$approvals (user_name,status,client_id,security_group_id,created_by,created_on,updated_by,updated_on) values(/*in:user_id*/?,/*in:status*/?,/*in:client_id*/?,/*in:tenant_id*/?,upper(/*in:user_id*/?),/*in:created*/?,upper(/*in:user_id*/?),/*in:created*/?), [tenant_id, in, class java.math.BigInteger], [client_id, in, class java.math.BigInteger], [user_id, in, class java.lang.String], [status, in, class oracle.dbtools.rt.oauth.ApprovalRequest$Status], [created, in, class java.sql.Timestamp]]with values: [adminlistener, APPROVED, 3858401374580004, -1, adminlistener, 2014-06-23 12:19:18.785, adminlistener, 2014-06-23 12:19:18.785]
SQL Developer responded with an Authentication Failed titled dialog with the following displayed in the body of the dialog
Cannot connect to DEV.

I am assuming this must be part of the problem I am seeing this the Weblogic deployment in my original post.
Does anyone have any suggestions on how best to tackle this?
