Java Web Start

As IE support is dying, Oracle have released a new way to launch the Java forms called Java Web Start – JWS.

JWS was introduced with R12.2.3 and in R12.1.3 with patches.

Have a look at this Oracle blog.

The low-down is you can enable JWS in 2 ways

1. Update the context file
2. Update profile options

As changing the context file needs a DBA so it is better just to update the profile options.

The two profile options we need are:

• Enable Java Web Start (code: FND_ENABLE_JAVA_WEB_START)
• ICX: Forms Launcher (code: ICX_FORMS_LAUNCHER)

Default values for legacy mode (URL is for R12.2.9 VISION instance):

• Enable Java Web Start: No
• ICX: Forms Launcher: http://apps.example.com:8000/forms/frmservlet

Value for JWS are:

• Enable Java Web Start: Yes
• ICX: Forms Launcher: http://apps.example.com:8000/forms/frmservlet?config=jws

To update the profile options we have 3 options:

1. Use the usual System Profile Options Java form (if you have access to this)
2. Use the web based form
3. Use a PL/SQL script

Note the profile options can also be set at user level but examples below are for site level only.

Java Form

As responsibility “System Administrator” navigate to: \Profile\System

Web Form

As responsibility “Functional Administrator” navigate to:
\Core Services\Profiles

PL/SQL Script

declare
	procedure set_site_value(p_profile varchar,p_value varchar) is
		l_result boolean;
	begin
		l_result:=fnd_profile.save(
			x_name=>p_profile,
			x_value=>p_value,
			x_level_name=>'SITE'
		);
	end;
	function get_site_value(p_profile varchar) return varchar is
		l_value varchar2(240);
		l_is_defined boolean;
	begin
		fnd_profile.get_specific(
			name_z=>p_profile,
			val_z=>l_value,
			defined_z=>l_is_defined
		);
		return l_value;
	end;
	procedure enable_browser is
	begin
		set_site_value('FND_ENABLE_JAVA_WEB_START','N');
		set_site_value('ICX_FORMS_LAUNCHER','http://apps.example.com:8000/forms/frmservlet');
	end;
	procedure enable_jws is
	begin
		set_site_value('FND_ENABLE_JAVA_WEB_START','Y');
		set_site_value('ICX_FORMS_LAUNCHER','http://apps.example.com:8000/forms/frmservlet?config=jws');
	end;
	procedure show_current is
	begin
		dbms_output.put_line('Current Settings');
		dbms_output.put_line('Enable Java Web Start: '||get_site_value('FND_ENABLE_JAVA_WEB_START'));
		dbms_output.put_line('ICX: Forms Launcher: '||get_site_value('ICX_FORMS_LAUNCHER'));
	end;
begin
	show_current;
	enable_jws;
	commit;
	show_current;
end;
