The run.bat (or the run.sh) is responsible for instantiating the JVM. These scripts do not look into the environment variables for JVM options. So you either have to change those scripts yourself to pick the values from environment variables or just (the easier and better way) is to set it directly in the run.bat. You define the Java configuration options in the TRANSFORMERJAVAOPTS environment variable. When defining Java configuration options, avoid defining duplicate options. If you do define duplicates, the last option passed to the JVM usually takes precedence. Setting Environment variables and System properties for Tomcat Server. Windows Environment: Create a file called setenv.bat in tomcat bin directory. Example: tomacta/bin/ setenv.bat. Set JAVAOPTS=% JAVAOPTS% -Djava.awt.headless=true The following is example for setting multiple properties.

That works for Linux (except for the leading # that turns it into a comment), but says nothing for Windows script or service usage. (The OP didn't bother to tell us the platform being used.)
If running from a Windows script, do the SET JAVA_OPTS before running startup.bat; if using Tomcat as a Windows service, use the Java tab of the tomcat6w.exe program to set up the options.

Java is a very popular programming language which provides a different component in order to run, develop Java applications. JRE or Java Runtime Environment is used to run Java application. JDK or Java Development Kit is used to develop Java applications. In this tutorial, we will learn how to set up Java, JRE, and JDK operating system path variables in order to work properly.
While adjusting some environment variables recently, I came across an odd issue with Docker, Spring Boot and JAVAOPTS. JAVAOPTS comes from the Tomcat/Catalina world and when searching for 'Docker and javaopts' on Google you'll find many references to just adding JAVAOPTS to the Docker environment. After some testing, I found this to be incorrect when running a Spring Boot jar in a Docker. BWJAVAOPTS='-Dname=value -Dname=value' MASHERYSERVICECONFIG Applications can pass TIBCO Mashery configuration through the MASHERYSERVICECONFIG environment variable. The value of the environment variable is a JSON string with the required TIBCO Mashery configuration.
Before starting the configuration we have to locate the JRE or JDK path. JRE or JDK generally installed on the
Program Files
or Program Files(x86)
directory under the Java directory like below.Java Java_opts Environment Variable
and under the
Java
directory the JDK is residing.Now we have learned the path of the Java, JRE or JDK installation. We can set this path as Java HOME_PATH environment variable. We will open the computer properties with by running
sysdm.cpl
in the Run menu like below. We can also open it from the File Explorer -> Computer -> Right Click.In the system properties, we will navigate to the
Advanced
tab which provides the Environment Variables
button like below.Set Java Opts
Below we can see the environment variables menu where we will create the
JAVA_HOME
system variable and set the path accordingly. We click to the New
in order to create a new system variable.![Java options environment variable Java options environment variable](/uploads/1/1/9/7/119731935/613088862.jpg)
Here we will set the
Variable Name
as JAVA_HOME
and the Variable Value
the path or Java, JRE or JDK which is C:Program FilesJavajdk-12
in this example. Then we will click OK.If we want to run
java.exe
or similar executables provided by JRE or JDK we have to add the path of Java in the Path
variable like below. We select the system variable named Path
and click to the Edit
.Here we click to
New
which will add a new line to the existing values._java_options Environment Variable Value
Here we will set the
bin
folder path which is C:Program FilesJavajdk-12bin
in this example.Java_opts Environment Variable In Jboss
Then we will click
OK
and OK
in the environment variables screen which will save and activated new path configuration.Java_opts Environment Variable
We can check the new path configuration simply opening a new command line interface MS-DOS. Then just type
java -version
which will execute java.exe
with the -version
option. We can see the current java binary version by running it.
