Hi I am seeing this issue on a RHEL4 box but i presume that the same will be for CentOS4.5 I am trying to get tomcat5 up and running using only upstream rpm's, as opposed to own rolled like i have done before, and hitting this issue. I have JAVA_HOME set in /etc/tomcat5/tomcat5.conf and also in /etc/sysconfig/tomcat5.conf and when tomcat is started using the init script it starts up like so tomcat 30676 0.1 1.4 1275052 60324 pts/0 Sl 08:45 0:03 /usr/java/sun/jdk/1.4.2_13/bin/java -server -Xms256m -Xmx1024m -Djava.security.manager=java.rmi.RMISecurityManager -Dcatalina.ext.dirs=/usr/share/tomcat5/shared/lib:/usr/share/tomcat5/common/lib -Dcatalina.ext.dirs=/usr/share/tomcat5/shared/lib:/usr/share/tomcat5/common/lib -Djava.endorsed.dirs=/usr/share/tomcat5/common/endorsed -classpath /usr/java/sun/jdk/1.4.2_13/lib/tools.jar:/usr/share/tomcat5/bin/bootstrap.jar:/usr/share/tomcat5/bin/commons-logging-api.jar:/usr/share/java/mx4j/mx4j-impl.jar:/usr/share/java/mx4j/mx4j-jmx.jar -Dcatalina.base=/usr/share/tomcat5 -Dcatalina.home=/usr/share/tomcat5 -Djava.io.tmpdir=/usr/share/tomcat5/temp org.apache.catalina.startup.Bootstrap start However in the catalina.out i see this WARNING: unable to set your JAVA_HOME. This may cause problems for any java applications you run ------------------------------------------------------------------------------- I am : tomcat on hostname JAVA_HOME : /usr/jdk1.3.1_08 Any ideas why this is and where that JAVA_HOME is coming from? thanks
