How I should fix java-path, in order to run tomcat?

I installed tomcat, set variables CATALINA_HOME=/opt/tomcat and CATALINA_BASE=/opt/tomcat. in terminal I entered command which java and got response /usr/bin/java. So how I understand this is path for JAVA_HOME. I set it. When I start tomcat in terminal with $CATALINA_HOME/bin/startup.sh I get response:

Using CATALINA_BASE:   /opt/tomcat
Using CATALINA_HOME:   /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/temp
Using JRE_HOME:        /usr/bin/java
Using CLASSPATH:       /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar
Tomcat started.

But when I check, I see that tomcat wasn't started and in logs I found:

/opt/tomcat/bin/catalina.sh: 1: eval: /usr/bin/java/bin/java: not found

I suppose,that something wrong with path to java. How can I fix it? PS everyhing was performed in Ubuntu OS

I think you should point your JRE_HOME to the directory where your java is installed, not the executable java itself. An example would be /usr/lib/jvm/java-7-oracle where that folder will contain the bin/java executable...

This one solved my issue: https://ubuntuforums.org/showthread.php?t=1018063

PS: I installed tomcat8 by apt-get instead of downloading the compressed tomcat file.

When the tomcat is started it is searching for setenv.sh in Catalina home or base.

Quote from Catalina.sh:

#   Do not set the variables in this script. Instead put them into a script
#   setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

#
#   JAVA_HOME       Must point at your Java Development Kit installation.
#                   Required to run the with the "debug" argument.

# Ensure that any user defined CLASSPATH variables are not used on startup,
# but allow them to be specified in setenv.sh, in rare case when it is needed.
CLASSPATH=

if [ -r "$CATALINA_BASE/bin/setenv.sh" ]; then
  . "$CATALINA_BASE/bin/setenv.sh"
elif [ -r "$CATALINA_HOME/bin/setenv.sh" ]; then
  . "$CATALINA_HOME/bin/setenv.sh"
fi

So best way to set JAVA_HOME in tomcat is through setenv.sh

  1. create a file setenv.sh in $CATALINA_HOME folder
  2. Add this line to it : "export JAVA_HOME=/usr/"
  3. Make it executable : "chmod 750 setenv.sh"

Start the startup.sh script, it will start the tomcat.

In Ubuntu

Set JAVA_HOME in .bashrc as export JAVA_HOME=/usr/lib/jvm/java-8-oracle/ and run . .bashrc then start tomcat server

For C shell (csh), edit the startup file (~/.cshrc):
set path=(/usr/local/jdk1.7.0/bin $path)

For bash, edit the startup file (~/.bashrc):

PATH=/usr/local/jdk1.7.0/bin:$PATH

export PATH For ksh, the startup file is named by the environment variable, ENV. To set the path:

PATH=/usr/local/jdk1.7.0/bin:$PATH

export PATH For sh, edit the profile file (~/.profile):

PATH=/usr/local/jdk1.7.0/bin:$PATH

export PATH Then load the startup file and verify that the path is set by repeating the java command:

For C shell (csh):

% source ~/.cshrc<br>
% java -version

For ksh, bash, or sh:

% . /.profile<br>
% java -version

You can also edit the file ../bin/setclasspath.sh and have an entry 

JAVA_HOME="##path of the java directory##"

This will make sure whenever you try to start the tomcat, the JAVA_HOME will be enforced.

Try to set up JAVA_HOME property in /etc/default/tomcat7:

JAVA_HOME=/usr/bin/java

This will force Tomcat to use JVM located under /usr/bin/java
