779844 - click-to-play doesn't work with java applets on talon.cz

Status: RESOLVED WORKSFORME

(Core Graveyard :: Plug-ins, defect)

Description

[Mikulas Patocka]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20100101 Firefox/14.0.1
Build ID: 20120713134347

Steps to reproduce:

go to about:config and enable plugins.click_to_play
go to www. talon.cz
click on "Vstoupit" button
there is a list of games in progress
click on "Pripoj se" to join a game



Actual results:

you get at error "problem with java" and the game won't load - there is nowhere to click to enable the java applet


Expected results:

the game should load after clicking on the applet

note that click to play works with Chrome on the same server

Neither does it with click-to-play functionality of the NoScript add-on when I click the placeholder (you need to have set that the way that plugins are blocked even on whitelisted sites).

Ignore what I previously said, it does work in general with NoScript's click-to-play setup (just not on one particular profile for me).

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:16.0) Gecko/20100101 Firefox/16.0

If plugins.click_to_play is enabled, java applets loaded from ".jar" files do not work. Java applets loaded from ".class" files work as expected.

Test scenario:
- html page contains the following element:
<applet id="Test" name="Test" archive="test.jar" code="com.Test.class" height="500" width="800">


If about:config - plugins.click_to_play is enabled, Web Console in firefox shows the following request:
Request URL: http://192.168.0.1:8080/testwebapp/com.Test.class  
Request Method: GET
Status Code: HTTP/1.1 404 Not Found

The source of the problem is that firefox tries to download the applet from file: "com.Test.class" (no such file exist on the webserver) - but it should download the applet from file: "test.jar" as specified in atribute "archive" in element <applet>

John would probably be the best person to look at this.

Does this still occur on Firefox beta or above? The click-to-play situation in 16 is not great.

Yes, in FF19, there is no gray overlay to activate Java plugin in the webpage, only the blue lego brick in the location bar.

From Loic's comment and what I'm seeing, it does work (e.g. you can click the plugin icon, activate the plugin, and it loads, eventually). The only thing is the overlay isn't showing in-content, which sounds exactly like bug 798623.

Comment 8

[Georg Fritzsche [:gfritzsche]]

I checked through FF17-19 and the situation is the same:
* Activation via the awesomebar icon / doorhanger works fine (AFAICT without knowing chzech)
* No click-to-play UI is shown in page due to the applet having height=25 (same as for object/embed elements)

Can someone confirm this?

Seems to work fine with FF17-19 on talon.cz with both:
* code=Marda.class archive=mprogC.jar,mres.jar
* archive=mprogC.jar,mres.jar code=Marda.class 
Is there a test-case that breaks with FF17+?

Closing as the issue seems to be fixed.
