Querying EBS data from APEX through PL/SQL process

Question

Hi all,
I have read through http://www.oracle.com/technetwork/developer-tools/apex/apex-ebs-wp-cabot-consulting-169064.pdf
and    http://www.oracle.com/technetwork/developer-tools/apex/learnmore/apex-ebs-extension-white-paper-345780.pdf
But I still do not have much idea on how do I query for data from ebs. What I am trying to achieve is to query for a table in EBS and put the data as a httpresponse
then parse the data using javascript by creating a html region in APEX.
Previously, I was creating an application process in the following manner
declare
element_List varchar2(4000) := '';
begin
begin
for i in (select END_MEASURE from SCS_ELEMENT_DATA where ATTRIBUTE10 = :P9_ASSET_ID) loop
element_List := element_List || i.END_MEASURE || ' ';
end loop;
exception when no_data_found then null;
end;
htp.prn(element_List);
end;
My table structure in EBS is something like this:
XXEAM_LAM_ELEMENTS (lam_element_id, csi_instance_id, element_name, element_desc, label, type, continuous, reference, shared, start_measure, end_measure, lat_long)
Would appreciate any advice as I'm new to both APEX and EBS.

Hi Scott and Tom,
Sorry about this.
My Apex is installed in the same instance as my EBS. I assume this means they are in the same DB? So if this is the case, can I just query with the EBS table name and the APEX application will know its EBS table and not APEX table?
Because previously my query was based on APEX tables and now I have query based on my EBS table using an APEX application process. I couldn't really understand what's needed even after looking through the whitepaper. I do not need to create a view/report based on the queried data because my APEX page only has a HTML region where I put all my javascript code in.
Hope this is clearer. Sorry for not being clear on my issue.
Regards,
