Hi, I added a section in the existing software page which I called "Bootstrapping the Java Software". https://confluence.slac.stanford.edu/display/hpsg/Installing+HPS+Software#InstallingHPSSoftware-BootstraptheJavaSoftware It covers installing lcsim and hps-java, as well as JAS. This is based on some emails to hps-software that covered how to "reset" the Java environment or build from scratch. --Jeremy ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
