Read every forum entry for OpenJDK and Jalimo. Then tried to download OpenJDK but was restricted from repository. Tried Jalimo but an instruction to disable "Red Pill" prevented me from the download. Read and looked at Java2Me again but it's not compressed for a Maemo Install. Although there has been some maemo.org members who have installed java on their N810, it wasn't enough info to do an informed install.
