[Biojava-l] install Biojava

[Richard HOLLAND]

This is a general Java problem, not a BioJava one. There is no such concept of "installing" a Java library, just the process of adding it to your classpath whenever you need it.

However... It sounds like you are logging out of your shell between each execution, hence it works for your first javac that is run in the same shell as the export command but not when you start another shell and run javac again without doing the export first. The classpath is only valid within your current shell session. If you want it to persist across all shell sessions, you have to add it to your user profile that is run when you start a shell, or to the system profile that is run for everyone when they start a shell. Or, write a wrapper script for javac that sets the classpath each time before calling the real javac.

cheers,
Richard
