Unable to find any JVMs

[DMan]

Fresh Express download.

Running startup.sh under Mac os x El Capitan.

results in

Unable to find any JVMs matching version "(null)".

No Java runtime present, try --request to install.

Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

At least one of these environment variable is needed to run this program

tried ./startup.sh --request

same result.

The Lucee installer doesn't have any instructions on what to download.

Any pointers appreciated.

Thanks,

D

Hi,

Just download and install the JRE from Oracle:

Kind regards,

Thanks, would be great if the message was updated to indicate what to do.

Andrew,

Does one have to point Lucee at the JRE somewhere in the configuration? I don't remember clearly.

Don't think so, I don't remember having to do that, but I've given up running Lucee and ACF on my local machine as Apple has this way of screwing the Apache config every time you upgrade Mac OS X, so now I run it and ACF on Linux VM's via VirtualBox so Apple can't mess with them.

Kind regards,

Andrew

Hmmm ... the message the OP got seems to come from bin/setclasspath.sh. 

If tomcat can't find the JRE after installation, what I dimly remember is that 

/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home

is a symlink and I ran a few commands to update it some months ago to get Lucee/Tomcat to use a newer version of Java. I don't know if this symlink is created on newer versions of OSX if and when a JRE is installed.

I prefer just to point to the jvm i want to use. In centos i use the service file which starts lucee:

 

[Unit]

Description=Tomcat

After=network.target

 

[Service]

Type=forking

User=tomcat

Group=tomcat

 

Environment=CATALINA_PID=/opt/tomcat/tomcat8.pid

Environment=TOMCAT_JAVA_HOME=/opt/jdk

Environment=CATALINA_HOME=/opt/tomcat

Environment=CATALINA_BASE=/opt/tomcat

#Environment=CATALINA_OPTS=

#Environment="JAVA_OPTS=-

ExecStart=/opt/tomcat/bin/startup.sh

ExecStop=/bin/kill -15 $MAINPID

 

[Install]

WantedBy=multi-user.target

 

 

JAVA-OPTS i tune in /opt/tomcat/bin/setenv.sh:

 

#! /bin/sh

# ==================================================================

 

CATALINA_HOME=/opt/tomcat

 

export CATALINA_OPTS="$CATALINA_OPTS -server"

export CATALINA_OPTS="$CATALINA_OPTS -Xms2048m"

export CATALINA_OPTS="$CATALINA_OPTS -Xmx2048m"

export CATALINA_OPTS="$CATALINA_OPTS -Xss256k"

export CATALINA_OPTS="$CATALINA_OPTS -XX:+UseG1GC"

export CATALINA_OPTS="$CATALINA_OPTS -XX:+ParallelRefProcEnabled"

export CATALINA_OPTS="$CATALINA_OPTS -XX:MaxGCPauseMillis=200"

export CATALINA_OPTS="$CATALINA_OPTS -XX:InitiatingHeapOccupancyPercent=70"

export CATALINA_OPTS="$CATALINA_OPTS -XX:G1ReservePercent=15"

export CATALINA_OPTS="$CATALINA_OPTS -XX:ParallelGCThreads=20"

export CATALINA_OPTS="$CATALINA_OPTS -XX:ConcGCThreads=5"

export CATALINA_OPTS="$CATALINA_OPTS -XX:+AggressiveOpts"

export CATALINA_OPTS="$CATALINA_OPTS -Djava.security.egd=file:/dev/./urandom"

export CATALINA_OPTS="$CATALINA_OPTS -javaagent:/opt/tomcat/lucee/lucee-inst.jar"

export CATALINA_OPTS="$CATALINA_OPTS -Doracle.jdbc.J2EE13Compliant=true"

 

# Check for application specific parameters at startup

if [ -r "$CATALINA_BASE/bin/appenv.sh" ]; then

  . "$CATALINA_BASE/bin/appenv.sh"

fi

 

echo "Using CATALINA_OPTS:"

for arg in $CATALINA_OPTS

do

    echo ">> " $arg

done

echo ""

 

echo "Using JAVA_OPTS:"

for arg in $JAVA_OPTS

do

    echo ">> " $arg

done

echo "_______________________________________________"

echo ""

 

 

 

Hope that helps

 

Michael
