     You don't need to set the value except for this.

< How to install InterStage 5.x >

In the Interstage 5.x, you can adjust JENNIFER installation process and LWST setting on INTERSTAGE_HOME>/conf/swatch.conf file. (Waring : jennifer.jar should be prior to servlet.jar.)

  This is swatch.conf data.

 sample.ipaddress=localhost
 sample.port=8009
 sample.log=true
 sample.containerconf=/etc/opt/FJSVjs2/jscontainer.xml
 sample.bin=/opt/FJSVawjbk/jdk14/bin/java
 sample.bin.parameters=-Dcom.fujitsu.interstage.jservlet.j2ee=true 
 -Xbootclasspath/p:/home/jennifer/agent/jennifersys.jar:/home/jennifer/agent/lwst30.sun.jar 
 -Djennifer.config=/home/jennifer/agent/w11.conf
 sample.env=CLASSPATH=/opt/FJSVawjbk/jdk14/lib/tools.jar
 sample.env=CLASSPATH=/opt/FJSVjs2/classes/jsboot.jar
 sample.env=CLASSPATH=/home/jennifer/agent/jennifer.jar
 sample.env=CLASSPATH=/opt/FJSVjs2/classes/servlet.jar
 sample.env=SHLIB_PATH=/home/jennifer/agent/jni/hp
