When I tested ppower4 in texlive2005-inst-20051027.iso on a system with Fedora Core 4 and a java package jre1.5.0_04, I got the following error: Invalid or corrupt jarfile Please fix the problem. Thank you. -- Lianjie Huang Mail Stop D443 Los Alamos National Laboratory Los Alamos, NM 87545, USA ~~~~~~ Correspondence/TSPA ~~~~~~
