X dies with message: “Could not init font path element unix/:7100”
You probably used your XF86Config file from a Red Hat system. Red Hat uses TCP port 7100 for its font server, while Gentoo does not. Find the line in your XF86Config file that says: ‘FontPath “unix/:7100”’ and comment it out. I don’t know why, but my Gentoo system seems to be running great without a specified font path. I have heard that changing the port number to -1 also works.
My understanding is this: J2ME (Java 2 Micro Edition) is for embedded systems development. If you don’t know what this is, then you don’t need it. If you are using JBoss or IBM’s Websphere, you might consider using the J2EE stuff (Enterprise Environment—server software and stuff). If you just want basic Java functionality, then download J2SE. The J2SE is the right program to download for most people. The J2SE consists of two parts: the JRE and the SDK. If you don’t want to program, then all you need is the JRE (Run-time Environment), which gives you the java interpreter. If you want to program, then you need the SDK (Software Development Kit), which includes a icompiler. The SDK includes the JRE—you don’t need to download both.
