R devel - Dec 2001 - Bug#123084: r-base: R documentatio search engine unusable with Mozilla 6 (OK with netscape 4.7x) (PR#1202)

As there is nothing Debian-specific in this bug report (and the .deb of the
JVW is not from Debian either), I am forwarding this to R-bugs. My
recollection from recent discussions on the R mailing list is that currently
/no/ browser other than Netscape supports the Java search engine -- is that
correct or was there some Netscape derivative (galeon?) which does?
Maybe the documentation should be enhanced in time for 1.4.0 to clarify this.

  Subject: Bug#123084: r-base: R documentatio search engine unusable with
Mozilla 6 (OK with netscape 4.7x)
  Date: Sun, 09 Dec 2001 16:04:49 +0100
  
  Package: r-base
  Version: 1.3.1-6
  Severity: normal
  
  The html-based doc system has problems with (the current builds of) Mozilla 6
:
  while the Java search engine does work in Netscape 4.77, it does *not* with
  Mozilla. The Netscape Java is, of course, 1.x, while Mozilla needs at least a
  j2re virtualm machine (I use the Blackdown's debian package of j2re1.3.1
and
  j2sdk :
  
  charpent@yod:~$ dpkg -l | grep j2
  ii  j2sdk1.3       1.3.1-1        Blackdown Java(TM) 2 SDK, Standard Edition
  charpent@yod:~$ 
  
  When I try to use the search engine (clicking the "Search engine"
anchor on the
  root page of the R documentation), I get a JVM error dialog box stating :

  The very same installation works pperfectly with Netscape (I just have to
lauch
  Netscape before invoking help.start(), which launches Mozilla by default).
  
  What am I missing ? Not much, as far as I can tell. Mozilla does not seem to
  have problems with Java (but I may be mistaken : I'm not much of a
"surfer").
  
  Therefore, I suspect that the SearchEngine.class code is somewhat java-1.1x
  specific.
