Today, there is no way to generate a WebDB component which can let you upload a file into the database. You would have to write a custom procedure to do this.
But the WebDB listener does support a very easy interface to move files into and out of the database. In your distribution, check for the files docload.sql and testdoc.sql. These are the procedures and tables that are integrated with the upload/download capability of the WebDB listener. These are a good example of how to use this functionality.
To see this sample code in action on your machine, execute http://<your_machine>/webdb/webdb.wwv_testdoc.show_form.
Note that the current version of the WebDB listener only supports upload/download from a LONG RAW column. You may see this change to native BLOB support in a future release.

When you say "once intermedia has generated the HTML format into a table", I'm assuming that you're referring to the CTX_DOC.FILTER and CTX_DOC.MARKUP procedures in the interMedia Text API to generate HTML renditions of the uploaded documents. Since the HTML rendition is placed into a CLOB, you can output this HTML with a procedure similar to:
create or replace procedure showdocs(
p_id number )
is
l_clob clob;
l_offset integer;
l_buffer varchar2(32767);
l_amt integer := 32767;
begin
select document into l_clob from context_markup where query_id = p_id;
l_offset := 1;
begin
loop
dbms_lob.read( l_clob, l_amt, l_offset, l_buffer );
htp.print(l_buffer);
l_offset := l_offset + l_amt;
l_amt := 32767;
end loop;
exception
when no_data_found then
null;
end;
end;

You can build your report against a table which has an interMedia Text index built on it. But you will have to choose the report based on a SQL query, and include a bind parameter in the CONTAINS function of your query (e.g., ...FROM doc_table
WHERE CONTAINS( content, :critera) > 0 )
