Hi frinds,

I’‘m new in Wildfire. I’‘ve a running Wildfire Server and now i’'d like to install a Connection Manager, so i downloaded the tar.gz files to another pc, followed all the steps of the installation guide, but when i tried to execute this error message is displayed:

daviar@kepler:~/Desktop/project/connection_manager/bin$ ./cmanager.sh

Can anybodu help me? This should run on a Ubunutu Breezy. I’'ve just installed the jre 1.5. and lincgj6 is installed and working too.

Hi,

it may help a lot to use Sun’'s JRE or JDK and not the GNU gij.

I think you are true. I installed the jre 1.5 that i downloaded from sun’'s website, but when i type java --version i get the following:

daviar@kepler:/opt/connection_manager/lib$ java --version

java version “1.4.2”

gij (GNU libgcj) version 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9)

How can i change this so when i call java, it will execute the re 1.5 version?

I’'ve now installed jre 1.4 with synaptic:

This is now the error message that i get when i run

Hi,

You should use JRE 1.5, not JRE 1.4. Try to start your connection manager this way:

JAVA_HOME=/usr/java/jre1.5.0_07 ./cmanager.sh

If you install JRE in different location, then change JAVA_HOME accordingly.

Ok, i did something by the way and it worked. You were right. It’'s because of the jre version. I have to upgrade my ubuntu, becuse in my reposiroties there is not a jre 1.5. I downloaded it from sun, but by default, shell runs the one ubuntu installed (1.4 gcj).

So what i do is to call the java vm using its absolute directory location (/usr/lib/j2re1.5-sun/bin/java). It worked.

Now i’'ve made my customized cmanager.sh with the locations vars of my system:

#!/bin/sh

  1. $RCSfile$

  2. $Revision: 1194 $

  3. $Date: 2005-03-30 13:39:54 -0300 (Wed, 30 Mar 2005) $

  1. tries to determine arguments to launch Connection Manager

  2. Set JVM extra Setting

  3. JVM_SETTINGS="-Xms512m -Xmx1024m"

JVM_SETTINGS=""

JAVA_HOME="/usr/lib/j2re1.5-sun/"

CMANAGER_HOME="/opt/connection_manager"

JAVACMD="$JAVA_HOME/bin/java"

  1. OS specific support. $var must be set to either true or false.

cygwin=false;

darwin=false;

case “uname” in

CYGWIN*) cygwin=true ;;

Darwin*) darwin=true

esac

CMANAGER_OPTS="$ -DmanagerHome=$" #set the CMANAGER_LIB location
CMANAGER_LIB="$/lib"
CMANAGER_OPTS="$ -Dcmanager.lib.dir=$"

LOCALCLASSPATH=$CMANAGER_LIB/startup.jar

cmanager_exec_command=“exec “$JAVACMD” -server $JVM_SETTINGS $CMANAGER_OPTS -classpath “$LOCALCLASSPATH” -jar “$CMANAGER_LIB”/startup.jar”

eval $cmanager_exec_command

Thank you very much because of your help. (A Spanish Friend)
