This is an expected warning message which you can ignore. The APR is the Apache Portable Runtime, which is a subset of the Apache HTTP Server C/C++ libraries that can be embedded within a web server. JBossAS will function just fine without it - it it cannot find APR it will use Java code to do the same work. If you would like to use APR within JBossAS, download and install JBoss Native.
