Setting Java Properties

Edit the WebLogic startup script for your platform to include the settings described in the following tables. Substitute the location of your JasperReports Server license file where necessary:

WebLogic Startup Settings on Windows
Filename	<wl-domain>binstartWebLogic.cmd
Settings	set JAVA_OPTIONS=%JAVA_OPTIONS% -Djs.license.directory=C:<js-install> -Dfile.encoding=UTF-8 -Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0 -Djavax.xml.soap.SOAPConnectionFactory=org.apache.axis.soap.SOAPConnectionFactoryImpl -Djavax.xml.soap.MessageFactory=org.apache.axis.soap.MessageFactoryImpl -Djavax.xml.soap.SOAPFactory=org.apache.axis.soap.SOAPFactoryImpl -Xms1024m -Xmx2048m -XX:PermSize=128m -XX:MaxPermSize=512m -Xss2m
For Oracle	set JAVA_OPTIONS=%JAVA_OPTIONS% -Doracle.jdbc.defaultNChar=true

Setting the Oracle localization option, defaultNChar, can substantially impact the performance of JDBC queries. If you don't need to support UTF-8 for your Oracle database, you can omit this setting.

WebLogic Startup Settings on Linux
Filename	<wl-domain>/bin/startWebLogic.sh
Settings	export JAVA_OPTIONS="$JAVA_OPTIONS -Djs.license.directory=/home/<user>/weblogic/jasperlicense/ -Dfile.encoding=UTF-8 -Dcom.sun.xml.namespace.QName.useCompatibleSerialVersionUID=1.0 -Djavax.xml.soap.SOAPConnectionFactory=org.apache.axis.soap.SOAPConnectionFactoryImpl -Djavax.xml.soap.MessageFactory=org.apache.axis.soap.MessageFactoryImpl -Djavax.xml.soap.SOAPFactory=org.apache.axis.soap.SOAPFactoryImpl -Xms1024m -Xmx2048m -XX:PermSize=128m -XX:MaxPermSize=512m -Xss2m"
For Oracle	export JAVA_OPTIONS="$JAVA_OPTIONS -Doracle.jdbc.defaultNChar=true"

Setting the Oracle localization option, defaultNChar, can substantially impact the performance of JDBC queries. If you don't need to support UTF-8 for your Oracle database, you can omit this setting.
