Hi Bhuneshwar
I am going on you referring to Apache Tomcat as the Java application you are trying to instrument
Can you advise in which file you added the startup parameters? and share the startup config? Just remove sensitive data please:)
Normally when no logs are generated it means that the agent has not been initialized when starting tomcat
Also please advise if you populated the configuration settings in the <java agent dir>/ver.xxx/conf/controller-info.xml file with the required controller details to connect?

rem Start/Stop Script for the CATALINA Server
rem
rem For supported commands call "catalina.bat help" or see the usage section
rem towards the end of this file.
rem
rem Environment Variable Prerequisites
rem
rem Do not set the variables in this script. Instead put them into a script
rem setenv.bat in CATALINA_BASE/bin to keep your customizations separate.
rem
rem WHEN RUNNING TOMCAT AS A WINDOWS SERVICE:
rem Note that the environment variables that affect the behavior of this
rem script will have no effect at all on Windows Services. As such, any
rem local customizations made in a CATALINA_BASE/bin/setenv.bat script
rem will also have no effect on Tomcat when launched as a Windows Service.
rem The configuration that controls Windows Services is stored in the Windows
rem Registry, and is most conveniently maintained using the "tomcat9w.exe"
rem maintenance utility.
rem
rem CATALINA_HOME May point at your Catalina "build" directory.
rem
rem CATALINA_BASE (Optional) Base directory for resolving dynamic portions
rem of a Catalina installation. If not present, resolves to
rem the same directory that CATALINA_HOME points to.
rem
rem CATALINA_OPTS (Optional) Java runtime options used when the "start",
rem "run" or "debug" command is executed.
rem Include here and not in JAVA_OPTS all options, that should
rem only be used by Tomcat itself, not by the stop process,
rem the version command etc.
rem Examples are heap size, GC logging, JMX ports etc.
rem
rem CATALINA_TMPDIR (Optional) Directory path location of temporary directory
rem the JVM should use (java.io.tmpdir). Defaults to
rem %CATALINA_BASE%\temp.
rem
rem JAVA_HOME Must point at your Java Development Kit installation.
rem Required to run the with the "debug" argument.
rem
rem JRE_HOME Must point at your Java Runtime installation.
rem Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME
rem are both set, JRE_HOME is used.
rem
rem JAVA_OPTS (Optional) Java runtime options used when any command
rem is executed.
rem Include here and not in CATALINA_OPTS all options, that
rem should be used by Tomcat and also by the stop process,
rem the version command etc.
rem Most options should go into CATALINA_OPTS.
rem
rem JAVA_ENDORSED_DIRS (Optional) Lists of of semi-colon separated directories
rem containing some jars in order to allow replacement of APIs
rem created outside of the JCP (i.e. DOM and SAX from W3C).
rem It can also be used to update the XML parser implementation.
rem This is only supported for Java <= 8.
rem Defaults to $CATALINA_HOME/endorsed.
rem
rem JPDA_TRANSPORT (Optional) JPDA transport used when the "jpda start"
rem command is executed. The default is "dt_socket".
rem
rem JPDA_ADDRESS (Optional) Java runtime options used when the "jpda start"
rem command is executed. The default is localhost:8000.
rem
rem JPDA_SUSPEND (Optional) Java runtime options used when the "jpda start"
rem command is executed. Specifies whether JVM should suspend
rem execution immediately after startup. Default is "n".
rem
rem JPDA_OPTS (Optional) Java runtime options used when the "jpda start"
rem command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,
rem and JPDA_SUSPEND are ignored. Thus, all required jpda
rem options MUST be specified. The default is:
rem
rem -agentlib:jdwp=transport=%JPDA_TRANSPORT%,
rem address=%JPDA_ADDRESS%,server=y,suspend=%JPDA_SUSPEND%
rem
rem JSSE_OPTS (Optional) Java runtime options used to control the TLS
rem implementation when JSSE is used. Default is:
rem "-Djdk.tls.ephemeralDHKeySize=2048"
rem
rem LOGGING_CONFIG (Optional) Override Tomcat's logging config file
rem Example (all one line)
rem set LOGGING_CONFIG="-Djava.util.logging.config.file=%CATALINA_BASE%\conf\logging.properties"
rem
rem LOGGING_MANAGER (Optional) Override Tomcat's logging manager
rem Example (all one line)
rem set LOGGING_MANAGER="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"
rem
rem TITLE (Optional) Specify the title of Tomcat window. The default
rem TITLE is Tomcat if it's not specified.
rem Example (all one line)
rem set TITLE=Tomcat.Cluster#1.Server#1 [%DATE% %TIME%]

Hi Bhuneshwar
I see you are using Java 9, can you add the startup setting to the setenv.bat file as advised in the AppDynamics documentation
Then try the following configurations in the setenv.bat file
Windows path directories are notorious for being problematic
Please try any of the following configurations
set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:"C:\<agent dir>\javaagent.jar" (with double quotes)
set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:C:\<agent dir>\javaagent.jar (without double quotes)
set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:C:/<agent dir>/javaagent.jar (replace backslashes with front slashes)
set CATALINA_OPTS=%CATALINA_OPTS% -javaagent:C:\\<agent dir>\\javaagent.jar (escape colon and backslash)
Ciao
