Java Options and JasperServer License Details

Setting Java JVM Options

To run properly, JasperReports Server needs more Java memory than the default settings. But for development work, the settings can be simpler than those recommended for production. For full information on recommended JAVA_OPTS settings, see the TIBCO JasperReports Server Installation Guide.

Tomcat and JBoss JVM Options

Here are some typical settings for JVM options that affect JasperReports Server. For space reasons, some of the options are displayed on multiple lines; make sure you set all options. These are the minimum recommended options; you may need to increase the JVM memory assignment according to your usage.

JVM Options on Windows

Options for all app servers

set JAVA_OPTS=%JAVA_OPTS% -Xms2048m -Xmx4096mset JAVA_OPTS=%JAVA_OPTS% -Xss2m -XX:+UseConcMarkSweepGC
Java 11 set JAVA_OPTS=%JAVA_OPTS% -Djava.locale.providers=COMPAT

For Oracle

set JAVA_OPTS=%JAVA_OPTS% -Doracle.jdbc.defaultNChar=true

JasperReports Server doesn’t provide a virtual X frame buffer on Linux. If your Linux applications are graphical, set the ‑Djava.awt.headless=true to prevent Java from trying to connect to an X-Server for image processing.

JVM Options on Linux and Mac OSX

Options for all app servers

export JAVA_OPTS="$JAVA_OPTS -Xms2048m -Xmx4096m"export JAVA_OPTS="$JAVA_OPTS -Xss2m"export JAVA_OPTS="$JAVA_OPTS -XX:+UseConcMarkSweepGC"
Java 11 export JAVA_OPTS="$JAVA_OPTS -Djava.locale.providers=COMPAT"

For Oracle

export JAVA_OPTS="$JAVA_OPTS -Doracle.jdbc.defaultNChar=true"

You can set JVM options in a number of ways. For example, you can add your JAVA_OPTS settings to these files:

File

Add JVM Options Below the Lines Shown Here:

<tomcat>\bin\setclasspath.bat

set JAVA_ENDORSED_DIRS=%BASEDIR%\common\endorsed

<tomcat>/bin/setclasspath.sh

JAVA_ENDORSED_DIRS="$BASEDIR"/common/endorsed

<tomcat>/bin/setenv.bat or

<tomcat>/bin/setenv.sh

JAVA_OPTS setting can go anywhere in this file.

<jboss>\bin\standalone.conf.bat

<jboss>/bin/standalone.conf

set JAVA_OPTS=%JAVA_OPTS% -Dprogram.name=%PROGNAME%

or

export JAVA_OPTS="$JAVA_OPTS -Dprogram.name=$PROGNAME"

For information on recommended JAVA_OPTS settings for all certified application servers, please refer to the TIBCO JasperReports Server Installation Guide.

Configuring the JasperReports Server License File

Commercial editions of JasperReports Server require a license file. The source code includes an evaluation license. You can use this license or replace it with the one you received from TIBCO Jaspersoft Technical Support (http://support.tibco.com) or your sales representative.

Configuring the License for All Application Servers

The main source build section describes placing a license in the home folder of the user running the application server. See Put jasperserver.license in Place.

Configure the License in the Tomcat Scripts

If you would like to locate your jasperserver.license in a specific folder, you can set a Java property in the shell script files used to control Tomcat.

JasperReports Server will look for a property named js.license.directory and use that folder as the location to find the jasperserver.license file.

For instance, if you want to point JasperReports Server to the license file in the root of the source package, update the following shell script:

Windows:

<tomcat>\bin\setclasspath.bat

Linux:

<tomcat>/bin/setclasspath.sh

And you could update the file with the following setting:

Windows:

set JAVA_OPTS=%JAVA_OPTS% "-Djs.license.directory=<js-src>"                        

Linux:

export JAVA_OPTS=$JAVA_OPTS -Djs.license.directory="<js-src>"                        

The jasperserver.license file can reside anywhere on the file system that's accessible from your application server. The js.license.directory setting should point to the folder containing the jasperserver.license.

You'll find more information on configuring the jasperserver.license for all certified application servers in the TIBCO JasperReports Server Installation Guide.
