I found that there are some compatibility issues between RHEL5 and SL5 in regards to how java 1.5.0 is being distributed. We have a beta astronomy package which depends on RedHat's java-1.5.0-sun (specifically it lists libjava.so as a requirement). Their repo does supply the required package, but yum removes the SL java-1.5.0-sun-compat as it conflicts with the Redhat packaging. I guess my question is why does SL use different packaging from the upstream vendor for java 1.5.0? -- Tony Hoffmann | Tel: (250)493-2277 | Fax: (250)493-7767 [log in to unmask] <mailto:[log in to unmask]> National Research Council Canada | P.O.
