Hi all, Sorry for the late reply on this. There were 2 issues with what I had done.
Issue 1 - "ClassNotFoundException : org.wso2.carbon.student.mgt.GetStudents" - Was able to get this fixed by removing the version tag of the "maven-bundle-plugin" plugin. Issue 2 - The name was not shown properly in the side bar of the carbon site. - In "components.xml", the end tag of the "i18n-bundle" element was on another line. This caused the menu item to show as "student.menu" rather than as "Students". Thanks for all the help.
