i'd like to test this, but i forgot where to put the mrj plugin on the mac. does
anyone know where it goes?

Comment 2

[Patrick C. Beard]

This is a actually an OJI/Plugins bug.

Comment 3

[Alex Musil]

Linux support is at least a week away.

Have you installed Patrick's MRJ plugin on the Mac?

What are you using to run java on Windows?  Are you using the latest installer?:

Comment 4

[Alex Musil]

Reassigning all OJI bugs to [e-mail]

Comment 5

[edburns]

Please make this applet available via the Internet.  I cannot verify this bug
until I can access the applet.

Comment 6

[Eli Goldberg]

[Chris Dreckman is on vacation; pinged petersen to confirm that he's okay with
the applet being attached to the test case as a formality. Will attach upon
hearing back from him. Thanks, Ed!]

Comment 7

[Eli Goldberg]

[Petersen said 'sure' on Friday; will attach the files today.]

Comment 8

[Eli Goldberg]

Test case is now available externally at http://www.prometheus-music.com/gecko/
5105/bft_browser_applet.html

(I can also zip and attach as an archive to the bug, but thought it would be
easier for you to just have them available by http.)

[chris hofmann]

moving to m10.  let me know if the fix is ready to see if we can get it
back on the m9 radar

elig:

How can I specify the HTTP proxy for the browser?  I can't access your test
applet.  You may just want to have it as an attachment.

Comment 11

[Eli Goldberg]

I've updated the URL text field to the location specified in 7.13.99 comment.
(There are 6 separate files, so I'd rather not add them as an attachments unless
necessary.)

Re: proxies. unfortunately, not yet supported; see bug #8559.

Comment 12

[edburns]

Now that proxy support works, I tested this bug, and the applet loads, but
crashes with this java stack trace.

The problem may be that I can't get the jdk to run through the http proxy
server.  I'll try that next.

moving to m11.  let me know if a fix comes available in the next few days. -

I specified the http proxy in the java control panel for JDK1.3, and now I get
this stack trace:

Now I'm back to the same thing as before, access denied when trying to resolve.

Comment 17

[edburns]

At this point, this is a configuration bug.  In order to check that it was
fixed from my site, inside of Sun Microsystem's firewall, I had to add the
following line to my C:\WINNT\SYSTEM32\drivers\etc\HOSTS file:

209.24.185.109  www.prometheus-music.com

After doing this, and restarting the browser, the applet properly displayed.
However, I cannot visit any other pages due to bug 14712.

I'm marking this as fixed, since it does indeed work.

Comment 19

[Paul Wyskoczka]

This site is now crashing with Windows build 1999122008 runnwing with NT 4.0

Comment 20

[Jeff Dyer]

What I am seeing on NT4.0 is a MSVC Debug Error in CJavaPluginView::SetWindow()
upon return from the method NS_IMETHODIMP
nsPluginInstancePeerImpl::GetParameter(const char* name, const char* *result)
defined in nsPlubinInstancePeer.cpp in mozilla/modules/plugins/nglsrc.
The call stack at this point looks like:
CJavaPluginView::SetWindow
CNetscapePlugin::SetWindow
nsPluginHostImpl::InstantiateEmbededPlugin

The Debug Error message says: "The value of ESP was not properly saved across a
function call. This is usually a result of calling a function declared with one
calling convention with a function pointer declared with a different calling
convention."

Since we have just called across the boundary between the Java Plugin and
Mozilla, I'm wondering if anything has changed with the calling conventions in
the plugin API.

Comment 21

[edburns]

Jeff,

It looks like something has changed in the browser that has broken the Java
Plugin.  I'm trying to get a working Java Plugin build so I can see exactly
what.

Comment 22

[edburns]

Set Target Milestone.

Comment 23

[edburns]

This works with non MOZ_DEBUG build.

    Comments: The null pData problem is believed to be from 27486.  Thus
    I'm marking this as a dup.
