Oracle Forms: How to display a HTML content without creating any file

10.05.2007 …

Par Francois Degrelle

For a checking out purpose, I would be able to display the HTML content of a Text Item in the default Internet Browser window.
My first thought was to create a HTML file on the local machine then call it with the Webutil functions:

client_text_io() functions to create the local file

client_host() function to launch the file into the Internet Browser

That does the job, but requires that Webutil is configured.
So I thought about eliminating all the Webutil stuff by concentrating all the logical within a single Web.Show_Document() call:

PROCEDURE HTML_Display
IS
 LC$Output Varchar2(32000);
 LC$Texte Varchar2(32000) := Name_In(:system.trigger_item) ;
Begin
 -- HTML output that needs no file generation ! --
 LC$Output := 'javascript:document.write("' ;
 LC$Output := LC$Output || '<html><body>' ;
 LC$Output := LC$Output || replace( LC$Texte, CHR(10), ' ') ;
 LC$Output := LC$Output || '</body></html>");' ;
 web.show_document(LC$Output,'_blank');
End;

Doesnt work in IE.. I tried it and found this Oracle forum posthttp://forums.oracle.com/forums/thread.jspa?messageID=1161101?The problem is actually caused as a result of recent Microsoft Security changes which prevents Forms from passing URLs to the browser which contain the prefix "javascript". In short, you can not longer use the "javascript" protocol in Forms with WEB_SHOW.DOCUMENT. This is not a bug, but rather a change in security.
