Can you please point me to document, that will provide me help me/ guide me to implement reporting feature (using Jasper report's .jxml files).  Not sure from where I need to start. It will great if there is any tutorial kind of document.

Currently I am using Netxms window client version 2.0-M2(8008)

I have done following
from  "https://www.netxms.org/download/archive/reporting/" I have download "netxms-reporting-server-2.0-M2.zip"
I have unziped it in Window and copied it to unix box where my netxms server (ntxmsd) is running

copied it to location /apps/uspsqa1/ntxms/netxms-reporting-server-2.0-M2
and did following steps

1. executed "nxdbmgr set EnableReportingServer 1"
2. created conf folder under "/apps/uspsqa1/ntxms/netxms-reporting-server-2.0-M2"
3. created workplace folder under ""/apps/uspsqa1/ntxms/netxms-reporting-server-2.0-M2"
4. created logback.xml under conf folder
5. created nxreporting.xml under conf folder
6. Now the folder looks like

    uspsqa1@mkeux805n-z1-76-SWITCH>> ls -ltra
    total 5920
    drwxr-xr-x  11 uspsqa1  uspsqa1      34 Sep  9 02:33 ..
    -rw-r--r--  1 uspsqa1  uspsqa1  2929061 Sep  9 02:33 nxreporting-2.0-M2.jar
    drwxr-xr-x  5 uspsqa1  uspsqa1        6 Sep  9 02:33 .
    drwxr-xr-x  2 uspsqa1  uspsqa1      79 Sep  9 02:33 lib
    drwxr-xr-x  2 uspsqa1  uspsqa1        4 Sep  9 02:48 conf
    drwxr-xr-x  4 uspsqa1  uspsqa1        4 Sep  9 02:49 workplace

    /apps/uspsqa1/ntxms/netxms-reporting-server-2.0-M2/workplace
    uspsqa1@mkeux805n-z1-76-SWITCH>> ls -ltra
    total 13
    drwxr-xr-x  5 uspsqa1  uspsqa1        6 Sep  9 02:33 ..
    drwxr-xr-x  2 uspsqa1  uspsqa1        2 Sep  9 02:49 definitions
    drwxr-xr-x  2 uspsqa1  uspsqa1        2 Sep  9 02:49 output
    drwxr-xr-x  5 uspsqa1  uspsqa1        5 Sep  9 02:49 .

7. When I executed "java -jar nxreporting-2.0-M2.jar", it produced several errors, kindly review the errors and
   let me know the corrections that I need to do, I have attached output of execution for your review

Also here are the content of my nxreporting.xml and logback.xml,
The path "/apps/uspsqa1/ntxms/netxms/etc/netxmsd.conf" valid path were I have server configuration
I have not given <datasource> info beacause I read that database details be collected from server configuration

content of "nxreporting.xml"
