i chose to install tomcat during the OS install as well as java....however, since I needed to use a different jvm, i used the method described in http://wiki.centos.org/HowTos/JavaOnCentOS for Sun jdk 1.5.0_13 and it worked fine as I can tell, as using the alternatives --config java command, i see both 1.4.2 and 1.5.0 versions and choosing the 1.5.0 version yields the right version when doing a "java -version" command....also doing a "which java" also points to the right location for the java 1.5.0 install...everything appears fine except that tomcat still sees java 1.4.2 as its jvm version... I have tried setting the path to JAVA_HOME in the tomcat5.conf as well as set the JAVA_HOME & JRE_HOME environment variable as a script under /etc/profiles.d....its as if tomcat is ignoring this and still using java 1.4.2! # /etc/init.d/tomcat5 version Server version: Apache Tomcat/5.5.20 Server built: Sep 27 2007 12:16:07 Server number: 5.5.20.0 OS Name: Linux OS Version: 2.6.18-8.1.15.el5 Architecture: i386 JVM Version: 1.4.2 JVM Vendor: Free Software Foundation, Inc. # java -version java version "1.5.0_13" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05) Java HotSpot(TM) Client VM (build 1.5.0_13-b05, mixed mode) # alternatives --config java There are 2 programs which provide 'java'.
