Thanks in advance.

To resolve the issue related to "The APR based Apache Tomcat Native library which allows optimal performance" you have to add a system property to the launch configuration of the tomcat server in eclipse.
-Djava.library.path=[tomcat_home]\bin
as well tcnative-1.dll 64/32 bit download and place it in bin folder.

The message "The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path" is not an error.
From your logs, the error is :
4:51:36 PM org.apache.tomcat.util.digester.Digester startElement
SEVERE: Begin event threw error java.lang.UnsupportedClassVersionError:
javax/servlet/http/HttpServletRequest : Unsupported major.minor version 51.0
Which means you are using java 6 to launch something compiled with java 7.
Are you sure you are using tomcat7 and not tomcat8?

You can change the eclipse tomcat server configuration. Open the server view, double click on you server to open server configuration. Then click to activate "Publish module contents to separate XML files". Finally, restart your server, the message must disappear.
This time page will come without any issues.

RealmBase Encryption Issue

and I am facing below error on executing the comman:
C:\Program Files\Apache Software Foundation\Tomcat 7.0>java -cp bin\tomcat-juli.jar;lib\catalina.jar;lib\tomcat-util.jar; org.apache.catalina.realm.RealmBase -a MD5 passwd

Try including servlet-api.jar as well.
java -cp bin\tomcat-juli.jar;lib\catalina.jar;lib\tomcat-util.jar;lib\servlet-api.jar org.apache.catalina.realm.RealmBase -a SHA passwd
EDIT
After trying to run this myself, there was yet another class missing. Instead of including every JAR in the classpath manually, I decided it would be easier to just include them all with lib\*. Try this...it works for me!
java -cp bin\tomcat-juli.jar;lib\* org.apache.catalina.realm.RealmBase -a SHA passwd
