I have developed a project using jersey 2 and spring 4,but i had to replace jersey 2 with jersey 1.19,when I did this i am getting an exception called "java.lang.ClassNotFoundException: com.sun.jersey.core.util.FeaturesAndProperties", when running on tomcat server.Is the migration from jersey 2 to jersey 1.19 causing this exception?.Thanks

Ways to handle these kind of problem-

First close your IDE and remove target, .setting and .classpath from your project directory.

1) Double check if you have multiple dependency of same with different version in pom.xml, if yes remove it and run command mvn clean install -U. If it's not work then

2) Find .m2 directory and inside this directory search for lastupdate file and remove all these files and run command mvn clean install -U. If it's not work then

3) Remove .m2 direcory and clean and install maven.
