JRE_HOME is the environment variable that points to your JRE installation. Often, these values are the same. I believe many utilities look for either or both of these variables. http://lmgtfy.com/?q=difference+between+JAVA_HOME+and+JRE_HOME > [r...@www2 conf]# which java > /usr/bin/java No help. You might want to do less work as "root". It's quite easy to really break things when you're root. How about: $ java -version > [r...@www2 conf]# alternatives --config java > There are 3 programs which provide 'java'. > Selection Command > ----------------------------------------------- > 1 /usr/lib/jvm/jre-1.4.2-gcj/bin/java > * 2 /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java > + 3 /usr/local/jdk1.6.0_20/bin/java Great, so you've got 3 Java versions installed: 1. GNU's Compiler for Java v1.4.2 2. OpenJDK v1.6.0 (64-bit version) 3. Sun's Java Development Kit v1.6.0_20 It's tough to tell from the output of "alternatives" which version is set by default. > [r...@www2 conf]# echo $JAVA_HOME > /usr/local/jdk1.6.0_20 That could indicate that Sun's JDK is currently enabled, but maybe not. How do you launch Tomcat? Try running this command and reporting the output: $CATALINA_HOME/bin/version.sh (Where CATALINA_HOME is the location of Tomcat; probably something like /usr/local/apache-tomcat-6.0.28) - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkw/VH8ACgkQ9CaO5/Lv0PBzwgCfSSxf/G+FoDu69UkIBc5gqIZo gloAoLyFWGvofEqWPLpKaZ94R5b1chof =wd+Y -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
