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.
It's very far from correct! The search engine works with Netscape 6.2 on Linux (and Windows), and with Internet Explorer and Opera 5 on Windows. (We were told it works with Internet Explorer on Linux too.) Opera uses Sun's 1.3.1, as I recall, so I don't think this is a Java-1.1 vs 1.3 issue. (I've just checked: Netscape 6.2 uses JRE 1.3.1.) What BTW is `Mozilla 6'? The current Mozilla is 0.9.6, so `6' seems a decade or so away. Which documentation do you suggest is altered and how? Given that the Mozilla-0.9.4-based Netscape 6.2 with JRE 1.3.1 works, the finger is pointing pretty insistently at a problem in the installation of `Mozilla 6', whatever that is, and/or its JRE.
