Many 4k applets not working

[pjt33]

@Alan_W

JNLP for applets only came in with plugin2 (which means Java 1.6u10+).
The code on Java4k isn’t friendly to the original plug in so Java 1.5 causes problems.

I know that pack200 does work on Java 1.5 on my Mac, because I tested it using Tomcat and the jnlpdownloadservlet. I would note that there are two valid mime types for java archives and Accept Encoding may arrive in upper or lowercase (or maybe even mixed case) - conclusion reached after reading servlet code. I also noted that the servlet code trims off any whitespace from the file name before appending .pack.gz. Could be the problems in the implementation detail on Java4k.

I’m pretty sure that the results I post above show that the problem is at least partly client-side and post-plugin2.

I’m pretty sure that the results I post above show that the problem is at least partly client-side and post-plugin2.

I did see you comments on AppletViewer, a somewhat flaky app in my opinion - It doesn’t meet spec on when the init() and start() methods are called w.r.t. window creation - and so am not entirely surprised that it doesn’t set Accept Encoding correctly. However I’m fairly certain the plugins do set it.

Edit: Note Accept and Accept-Encoding header fields are different!

GET /applets/applet-5.7.0.2.jar HTTP/1.1
content-type: application/x-java-archive
accept-encoding: pack200-gzip,gzip
Cache-Control: no-cache
Pragma: no-cache
User-Agent: Mozilla/4.0 (Windows XP 5.1) Java/1.6.0_03
Accept: text/html, image/gif, image/jpeg, ; q=.2, /; q=.2

Also need to check substring in Accept-Encoding as different browsers will send different things in the comma separated list. servelet does:

encoding.toLowerCase().indexOf(PACK200_GZIP_ENCODING) > -1){

Silly Question: Does Appletviewer support pack200? [After testing - coming to conclusion it does not]
