Reports output in PDF does not save on client machine - Weblogic

Dear Community Members,

We are migrating our application from Forms 6i to Forms 11g,

We are using Weblogic 10.3.6 and Report Builder 11.1.2.2.0 and database Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

We calls the report with parameter form=Yes thru form, we have set the system parameter in the report as desname=c:\attachments\inspect.pdf, Destype=File,

The report opens in browser, but do not save on client machine.

We use following coding to call the report from form:

==========================================================================

vc_user_name := get_application_property(username);

vc_user_password := get_application_property(password);

vc_user_connect := get_application_property(connect_string);
