Demo Jr. Launch UBE from Web

Try to launch a UBE with P98305 (fast path BV) from web client of a Demo Jr. but get a message saying "Local submission is not supported from skinny batch versions/menus."
But, the web client does support launching UBE at local. For example, P0011 can submit R09801 while Post by Batch is selected.
I wonder a little code change can make the launch UBE work in P98305 so that users can get better idea of running JDE with even a demo jr. This is also very helpful if demo jr is used for a training.

Try this:
=============================================================
The following instruction is the setup to allow for running of UBE from web interface.
--------------------------------------------------------------------------------------
1. Start E1 Solution Explorer.

2. Go to command prompt and type HOSTNAME to determine your local PC local host name.

3. Go to P986115 - Row exit until the maintenance form for "Data Source Revisions"
Change "Logical Server Name" to the local HOSTNAME.
Change "Server Map Data Source Name" to "System Local"
Click OK to update.

4. Reboot. Start E1 Solution Explorer.

5. Go to P98616 and define the DEFAULT printer with the default paper size.
Setup DEFAULT printer via P98616 for the local HOSTNAME.
Setup for for HOSTNAME, (local) and LOCAL. This will allow you to submit UBE from web-client.

6. Reboot. Start E1 Solution Explorer. Start E1 Web.

Could anyone help with setting UBE submit on DEMO 9.2? The solution that mentioned above does not work for me.
