VM parameters
If there are any VM parameters you would like to specify for the
invocation of your Java application, you can enter them here (e.g.
-Dmyapp.myproperty=true or -Xmx256m).
There are several runtime-variables you can use to specify runtime directories:
-
%EXE4J_EXEDIR%
This is the directory where the executable is located.
-
%EXE4J_JVM_HOME%
This is the directory of the JRE that your executable is running with.
-
%EXE4J_TEMPDIR%
For the "JAR in EXE" mode, this
variable will contain the location of the temporary directory for the JAR files.
In "regular mode" this variable is
not used.
These variables can be especially useful for adding JAR files to the bootclasspath.
In addition to these VM parameters, a parameter file in the same directory as the executable
is read and its contents are added to the existing VM parameters. The name of this parameter
file is the same as the exe file with the extension *.vmoptions.
For example, if your exe file is named hello.exe, the name of the VM
parameter file is hello.vmoptions. In this file, each line is
interpreted as a single VM parameter. For example, the contents of the VM parameter
file could be:
-Xmx128m
-Xms32m
In addition to the VM parameters you can also modify the classpath in the *.vmoptions files with the
following options:
-
-classpath [classpath]
Replace the classpath of the generated launcher.
-
-classpath/a [classpath]
Append to the classpath of the generated launcher.
-
-classpath/p [classpath]
Prepend to the classpath of the generated launcher.
You can use environment variables in the VM parameters with the following syntax:
${VARIABLE_NAME} where you replace VARIABLE_NAME with the desired
environment variable.
