This is OK, because in the tomcat configuration in the jboss/tomcat integration there is no default webapp configured.
Deploy an webapp and try http://localhost:8080/webapp to check if everything works fine.
What I wanted is that How to access the servlets deployed in the tomcat server? Is there any way for that.

It's the same way as you would if you were running tomcat in standalone mode.
Look at the tomcat documentation for an example.
You write your servlets, you put them somewhere where tomcat can find them and then write a WEB.xml file with your config.
.jsp Files can be accessed with http://localhost:8080/webapp/path_to_your_jsp_file.jsp
