# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
export CATALINA_HOME=/home/hostname/apache-tomcat-6.0.35

#tomcat自启动
