  • I have to use their ROES software which is Java based. The upload tool for the online gallery provider also is Java based. I can't place any orders or upload any photos to my galleries as none of the programs will work. I've contacted all of the companies. They are telling me that the last update Apple did on 2/1 is causing the problem with Java.
  • Java mac free download - Java Update for Mac OS X 10.3.9, Apple Java for OS X 10.6, Apple Java for OS X 10.5, and many more programs.
