Resolution:
Here is the correct way to install a tomcat servlet engine as an NT service:
1. In DOS command prompt -
cd &ltbwwf home>/5.1/bin

2. Run -
tomcatservice.bat &ltyour service name> &ltbwwf home>/5.1/tomcat/conf/server_&ltserver name>-&ltport>.xml &lttibco home>/tra/5.5 &lttibco home>/tpcl/5.5

3. To uninstall the service run -
&ltbwwf home>/5.1/tomcat/bin/tomcat -uninstall &ltservice name>


If the bwwf has been upgraded to the other higher version of bwc, we can just change the above value of
&ltbwwf home>/5.1
to
&ltbwc home>/&ltversion>.
