prunsrv.exe Service not starting up

I am trying to install and start a service with prunsrv.exe for an application

I am able to install the service alright but the service wont start up and gives me an error

Also following is the configuration that is used to install the service using prunsrv.exe

set SERVICE_NAME=TestService

REM Service log configuration
set PR_LOGPREFIX=%SERVICE_NAME%
set PR_LOGPATH=D:\setups\Commons_Daemon\commons-daemon-1.0.14-bin-windows\logs
set PR_STDOUTPUT=auto
set PR_STDERROR=auto
set PR_LOGLEVEL=INFO

REM Path to java installation
set PR_JVM=C:\Program Files\Java\jre1.6.0_04\bin\client\jvm.dll
set PR_CLASSPATH=D:\setups\Commons_Daemon\commons-daemon-1.0.14-bin-windows\temp.jar;

REM Startup configuration
set PR_STARTUP=auto
set PR_STARTMODE=java
set PR_STARTCLASS=Trys.AppLauncher
set PR_STARTMETHOD=start

REM Shutdown configuration
set PR_STOPMODE=java
set PR_STOPCLASS=Trys.AppLauncher
set PR_STOPMETHOD=stop

REM JVM configuration
set PR_JVMMS=64
set PR_JVMMX=128
set PR_JVMSS=4000

REM Install service
prunsrv.exe //IS//%SERVICE_NAME%

The above config is packaged to a batch file is executed to install the service

Also the log files are not generated, due which i cant even debug.

Please tell me where i am going wrong

The reason for this error was that i did not rename prunsrv.exe to TestService.exe. Similarly Prunmgr.exe has to be TestServicew.exe.

Very important that these files are renamed.
