16778 - JavaServer Admin Tool applet can't be loaded, throws NPE.

Status: VERIFIED FIXED

(Core Graveyard :: Java: OJI, defect, P3)

Description

[Leila Garin]

Using 10/11/99 build of Mozilla on WinNT and jdk1.3 early access release.
This happens on MAC too.

To reproduce the bug, you need to install the JavaWebServer 1.1.X version.
Then, bring up the JavaServer Administration Tool applet on apprunner by
entering http://<hostname>:9090/. A concrete example is http://lonely:9090/.
Upon loading the applet, a NullPointerException is thrown. Here's the stack
trace,

Don't have time to get to this, or to have a Sun Java Web Server person look at
this stack trace.  Will try to get to it later.

Moving way out, and copying Raju Pallath (new Blackwood QA contact on this one). 
 Leila, when you get a chance (sometime in the next month or so), would you 
please help Raju set up the environment to reproduce this bug?  It may be fixed 
by recent changes in Java Plug-In and Mozilla.

Tried on WinNt4.0 with SP5.

Used nightly build of mozilla dated 03/05/2000 with JRE RC1 from JDC site
and applied patched plugin zip file (from George).

The applet does load correctly and no exceptions are thrown.
