PL/PDF - Procedure test1 is executed but gives error

Question

Hello All,
I have Oracle XE 10g with Oracle Apex and recently I installed PL/PDF in the same. I tried to execute the headerfooter procedure given in the installation guide. But it gives error ORA-20000: ERR-006 Procedure call error: xxfooter. How can I get the header and footer from this procedure headerfooter?
- create header footer procedure
CREATE OR REPLACE procedure headerfooter is
/* 7. Example: Header, Footer, number of pages */
l_blob blob;
begin
/* Initialize, without parameters means:
- page orientation: portrait
- unit: mm
- default page format: A4 */
plpdf.init;
/* Defines the page number alias.
Default: {nb} */
plpdf.nopAlias;
/*Sets the page header procedure name. The program name passed
as a parameter executes when the page header is created. */
plpdf.SetHeaderProcName(
p_proc_name => 'xheader', -- Page header procedure name: xheader
p_height => 10 -- Height of header section
/* Sets the page footer procedure name. The program name passed
as a parameter executes when the page footer is created. */
plpdf.SetFooterProcName(
p_proc_name => 'xfooter', --Page footer procedure name: xfooter
p_height => 10 --Height of footer section
/* Begin a new page, without parameters means:
- page orientation: default (portrait) */
plpdf.NewPage;
/* Sets the font and its properties */
plpdf.SetPrintFont(
p_family => 'Arial', -- Font family: Arial
p_style => null, -- Font style: regular (default)
p_size => 12 -- Font size: 12 pt
/* Draws a rectangle cell with text inside. */
plpdf.PrintCell(
p_w => 50, -- Rectangle width
p_h => 10, -- Rectangle heigth
p_txt => 'Page 1' -- Text in rectangle
/* Begin a new page, without parameters means:
- page orientation: default (portrait) */
plpdf.NewPage;
/* Draws a rectangle cell with text inside. */
plpdf.PrintCell(
p_w => 50, -- Rectangle width
p_h => 10, -- Rectangle heigth
p_txt => 'Page 2' -- Text in rectangle
/* Returns the generated PDF document.
The document is closed and then returned in the OUT parameter. */
plpdf.SendDoc(
p_blob => l_blob -- The generated document
/* Print it:*/
     owa_util.mime_header('application/pdf',false);
htp.p('Content-Length: ' || dbms_lob.getlength(l_blob));
owa_util.http_header_close;      
wpg_docload.download_file(l_blob);
end;
-Create footer procedure
CREATE OR REPLACE procedure xfooter is
begin
/* Sets the font and its properties */
plpdf.SetPrintFont(
p_family => 'Arial', -- Font family: Arial
p_style => 'I', -- Font style: Italic
p_size => 8 -- Font size: 8 pt
/* Print number of page */
/* Draws a rectangle cell with text inside. */
plpdf.PrintCell(
p_w => 0, -- Rectangle width
p_h => 10, -- Rectangle heigth
p_txt => to_char(plpdf.CurrentPageNumber) || '/{nb}', -- Text in rectangle
p_border => '0', -- Without frame
p_ln => '0', -- Cursor position after the cell is printed: Beside
p_align => 'C' -- Text alignment: Center
end;
Thanks.

Thanks for your reply,
Since the owner of header/footer procedures is different than plpdf, I should have given the grants to plpdf schema but unfortunately I missed. Thanks for the answer it worked. Instead of creating synonyms for the procedures in plpdf schema I am passing procedure name with qualifier, the name of its owner, to plpdf api (owner.procedure_name).
