Hello all, I'll assume this has already been addressed, so a pointer to a good solution to try would help. But if not, here's my prob. I just got Fedora 10 with ds-base installed: yum info fedora-ds-base Loaded plugins: refresh-packagekit Installed Packages Name : fedora-ds-base Arch : i386 Version : 1.1.3 Release : 6.fc10 Size : 4.6 M And everything looks great: #/usr/bin/fedora-idm-console -a http://localhost:9830 Until I try to Open the Directory Server tree with the following errors.... Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException ... I've read something about an OpenJDK 1.5.0 versioning problem, but I can't seem to find anything earlier than OpenJDK 1.6.0 ... Any ideas?
