Posting Data to OTM using HTTP request

Any external system like EBS, SAP can frame this XML structure programatically and 'POST' this xml to OTM Integration servlet: glog.integration.servlet.WMServlet

Below is an PLSQL program posting Location element to OTM:

DECLARE

-- This is OTM Application URL Where string after GC3 is replaced as shown below
v_chr_url VARCHAR2(1000) := 'http://OTM-SERVER:7777/GC3/glog.integration.servlet.WMServlet';

-- This is OTM USER from which transmission needs to be created
v_otm_user VARCHAR2(100) := 'DBA.ADMIN';

-- This is password for the OTM USER
v_otm_pwd VARCHAR2(100)  := 'CHANGEME';

-- You can programtically from the xml string and pass it to this variable
    v_data_in          VARCHAR2 (10000);
      v_http_req         UTL_HTTP.req;
      v_http_resp        UTL_HTTP.resp;
      v_chr_resp_val     VARCHAR2 (3000);

BEGIN
-- This is a sample transmission that creates location(Shipment Management -> --Shipment Management -> Location Manager) in OTM
-- Note that in the Transmission Body, GLOGXMLElement chosen here is Location. By --choosing appropriate element, you can load required data.
--In this script file, you see XML structure to send location information.
--You can get this structure by referring the GLOGXML.xsd
--Navigation to fetch this from OTM.

Note that if you have multiple integrations to be built from external system to OTM system to load data coming in different formats like EDI, text files, etc you should typlically go for a middleware tool like Oracle SOA(BPEL), Webmethods etc to translate these files from various formats to XML format defined by GlogXML schema.
