      I was not seeing consistent usage in the shell scripts of the following:

      • org.apache.geronimo.base.dir

      In 4 of the scripts, GERONIMO_BASE was used where GERONIMO_HOME should have been used, or GERONIMO_BASE should be used to complete the path to the temp file, otherwise the GeronimoInstallationPath is used to complete the temp file path.
      The attached patch corrects these.

      For more information, please see my thread on user@geronimo.apache.org
      Subject: GERONIMO_BASE vs. GERONIMO_HOME and org.apache.geronimo.base.dir

      And as an additional note, this patch resolves a few errors, but not these two:
      Using GERONIMO_BASE: /usr/local/geronimo/server1
      Using GERONIMO_HOME: /usr/local/geronimo
      Using GERONIMO_TMPDIR: var/temp
      Using JRE_HOME: /usr/jdk1.5.0_07/jre
      10:45:33,914 ERROR [LocalAttributeManager] Caught exception java.io.FileNotFoundException: /usr/local/geronimo-jetty6-javaee5-2.1.1/var/config/config-substitutions.properties (No such file or directory) trying to open properties file /usr/local/geronimo-jetty6-javaee5-2.1.1/var/config/config-substitutions.properties
      Geronimo looks for the 'var/config/config-substitutions.properties' file according to 'org.apache.geronimo.server.dir' variable.
      However the bin/geronimo.sh script only sets -Dorg.apache.geronimo.base.dir=$GERONIMO_BASE
      But I do not see how org.apache.geronimo.base.dir is used inside Geronimo.
      To fix we would have to set the variable -Dorg.apache.geronimo.server.dir=$GERONIMO_BASE too - but we cannot do that if we want users to be able to supply the -Dorg.apache.geronimo.server.name=<relative_path> variable outside of bin/geronimo.sh in $GERONIMO_OPTS env var.
      So I could not figure out a good way to address this error, unless we overrided org.apache.geronimo.base.dir variable with whatever is in the org.apache.geronimo.server.dir variable, then change Geronimo to look for the configSubstitutionFile as '<org.apache.geronimo.base.dir>/var/config/config-substitutions.properties'
      And it appears that Geronimo ignores org.apache.geronimo.base.dir in favor of org.apache.geronimo.home.dir anyway, so removing the configured org.apache.geronimo.base.dir property in bin/geronimo.sh does not seem to hurt anything - at first test, at least, it works for me.
      Then we just always set org.apache.geronimo.base.dir = org.apache.geronimo.server.dir
      I would appreciate if someone shed light on the proper intended usage of the org.apache.geronimo.base.dir property.
      Using GERONIMO_BASE: /usr/local/geronimo/server1
      Using GERONIMO_HOME: /usr/local/geronimo
      Using GERONIMO_TMPDIR: var/temp
      Using JRE_HOME: /usr/jdk1.5.0_07/jre
      The java.io.tmpdir system property specifies a non-existent directory: /usr/local/geronimo-jetty6-javaee5-2.1.2/var/temp
      read: /usr/local/geronimo/bin/geronimo.sh

      1. GERONIMO_TMPDIR (Optional) Directory path location of temporary directory
      2. the JVM should use (java.io.tmpdir).
      3. Defaults to $GERONIMO_BASE/var/temp.
        if [ -z "$GERONIMO_TMPDIR" ] ; then
      4. Define the java.io.tmpdir to use for Geronimo
      5. A relative value will be resolved relative to each instance
        This is incorrect documentation, as the error message illustrates.
        GERONIMO_TMPDIR does not default to $GERONIMO_BASE/var/temp
        Nor does it default to $GERONIMO_HOME/var/temp
        Instead: It defaults to <Geronimo_install_directory>/var/temp
        Or also org.apache.geronimo.server.dir/var/temp
        GERONIMO_TMPDIR should be set with $GERONIMO_BASE/var/temp
        Or also org.apache.geronimo.base.dir/var/temp to comply with the documentation
        Setting GERONIMO_TMPDIR="$GERONIMO_BASE"/var/temp in bin/geronimo.sh will actually conflict with anyone using the -Dorg.apache.geronimo.server.name=<relative_path> to run multiple instances as documented in the geronimo wiki.
        The absolute path is resolved to <org.apache.geronimo.server.dir>/<java.io.tmpdir> IF <java.io.tmpdir> is a relative path.
        So setting the absolute path in bin/geronimo.sh would require the user to additionally specify the absolute path of $GERONIMO_TMPDIR into their geronimo instance.
        The change, causing the property org.apache.geronimo.base.dir to be used, would have to be completed internally in the java classes that set the properties.

      How To Produce The Errors the attached patch fixes:
      1) expand geronimo-jetty6-javaee5-2.1.2 in /usr/local/
      2) cd /usr/local; ln -s geronimo-jetty6-javaee5-2.1.2 geronimo
      2) create the directory /usr/local/geronimo/server1
      3) move /usr/local/geronimo/var to /usr/local/geronimo/server1/var
      4) start geronimo with this shell command:
      cd /usr/local/geronimo
      export GERONIMO_HOME=/usr/local/geronimo
      export GERONIMO_BASE=/usr/local/geronimo/server1
      exec ${GERONIMO_HOME}/bin/startup.sh

      $ cat /usr/local/geronimo/server1/var/log/geronimo.out | grep '[java.*.dirs]'
      10:45:33,955 INFO [Log4jService] System property [java.endorsed.dirs] = /usr/local/geronimo/server1/lib/endorsed:/usr/jdk1.5.0_07/jre/lib/endorsed
      10:45:33,955 INFO [Log4jService] System property [java.ext.dirs] = /usr/local/geronimo/server1/lib/ext:/usr/jdk1.5.0_07/jre/lib/ext
      read: /usr/local/geronimo/bin/geronimo.sh

      1. For Cygwin, switch paths to Windows format before running java
        if $cygwin; then
      2. Setup the Java programming language agent
        There is no such directory as '/usr/local/geronimo/server1/lib/'
        but the bin/geronimo.sh script uses GERONIMO_BASE to point at the lib directory.
        That should be $GERONIMO_HOME
        The same for JAVA_AGENT_JAR which points at /usr/local/geronimo/server1/bin/jpa.jar in this example
        GERONIMO_HOME is used only for the scope of the shell scripts, and everything else uses it only for starting Geronimo, so we should be consistent.
