When I doing the merlin-beta download/install test,use the bundles j2re-1_4_0-beta-solsparc.sh.
I find when I install it on s8 or s7 machine,
and I set path use 'export PATH=<jre installed dir>/bin' and 'export NPX_PLUGIN_PATH=<jre installed dir>/plugin/sparc/ns4', then start netscape to view the <jre installed dir>/ControlPanel.html, this java plugin program couldn't display in the browser, and it's also couldn't display other plugin program like http://192.9.48.9/products/plugin/1.3/demo/applets.html.

but it's ok when use ladybird fcs version.
