------ Solution ---------------------------------------- ----
with demand answers. . . . . .
------ For reference this is my only ---------------------------------------
convert the word html method ( refer to someone else's )
public boolean changeFormat (String FileName) {

String FileFormat = "";
FileFormat = FileName.substring (FileName.length () -4, FileName.length ());
System.out.println (FileFormat);

if (FileFormat.equalsIgnoreCase (". doc")) {
String DocFile = FileName;

System.out.println ("word file path :" + DocFile);
/ / word file's full path

String HtmlFile = DocFile.substring (0, (DocFile.length () ; - 4)) + ". htm";

System.out.println ("htm file path :" + HtmlFile);
/ / html file's full path

ActiveXComponent app = new ActiveXComponent ("Word.Application");
/ / start word

try
{
app.setProperty ("Visible", new Variant (false));
/ / set non-visual word program operation

Dispatch docs = app.getProperty ("Documents" ;). toDispatch ();

/ / Save the file as htm format

Dispatch.call (doc, "Close", new ; Variant (false));
/ / close the file

}
catch (Exception e) {
e.printStackTrace ();
}
finally {
app.invoke ("Quit", new Variant [ ] { } ) ;
/ / exit word program
}
/ / conversion is completed
return true;
}
return false;
}
------ For reference only ------------------------- --------------
this issue is resolved , the reason is : itext html to pdf format more stringent requirements on the html , html pages can be added to this
