org glassfish jersey servlet ServletContainer ClassNotFoundException

Question

I have been getting a ClassNotFoundException with org glassfish jersey servlet ServletContainer but it peculiarly started last night when I tried to start re-start my Tomcat server  v7  with Eclipse Juno    Not sure what is going on  What s bizarre is that it just started happening last night while it was working perfectly well before that   Here is the stacktrace   Feb 25  2014 11 11 19 AM org

If you are using Jersey 2 x use following dependency      lt dependency gt      lt groupId gt org glassfish jersey containers lt  groupId gt      lt artifactId gt jersey-container-servlet-core lt  artifactId gt      lt version gt 2 XX lt  version gt   lt  dependency gt      Where XX could be any particular version you look for  Jersey Containers

I agree with the accepted answer  But for me  the issue was not that  instead I had to modify my Servlet-Class name from -    lt servlet-class gt org glassfish jersey servlet ServletContainer class lt  servlet-class gt     To    lt servlet-class gt org glassfish jersey servlet ServletContainer lt  servlet-class gt    So  removing  class worked fine in my case  Hope it will help somebody

The jersey-container-servlet actually uses the jersey-container-servlet-core dependency  But if you use maven  that does not really matter  If you just define the jersey-container-servlet usage  it will automatically download the dependency as well   But for those who add jar files to their project manually  i e  without maven  It is important to know that you actually need both jar files  The org glassfish jersey servlet ServletContainer class is actually part of the core dependency

If you not use maven  try to put your jars to WEB-INF lib  it worked for me

It s an eclipse setup issue  not a Jersey issue   From this thread ClassNotFoundException  org glassfish jersey servlet ServletContainer  Right click your eclipse project Properties -  Deployment Assembly -  Add -  Java Build Path Entries -  Gradle Dependencies -  Finish   So Eclipse wasn t using the Gradle dependencies when Apache was starting

The problem   java lang ClassNotFoundException  org glassfish jersey servlet ServletContainer   indicates that you try to use the Jersey 2 x servlet  but you are supplying the Jersey 1 x libs   For Jersey 1 x you have to do it like this      lt servlet gt     lt servlet-name gt Jersey REST Service lt  servlet-name gt   lt servlet-class gt    com sun jersey spi container servlet ServletContainer  lt  servlet-class gt     lt init-param gt       lt param-name gt com sun jersey config property packages lt  param-name gt       lt param-value gt sample hello resources lt  param-value gt     lt  init-param gt     lt load-on-startup gt 1 lt  load-on-startup gt   lt  servlet gt   lt servlet-mapping gt     lt servlet-name gt Jersey REST Service lt  servlet-name gt     lt url-pattern gt  rest   lt  url-pattern gt   lt  servlet-mapping gt    For more information check the Jersey 1 x documentation   If you instead want to use Jersey 2 x then you ll have to supply the Jersey 2 x libs  In a maven based project you can use the following    lt dependency gt       lt groupId gt org glassfish jersey containers lt  groupId gt       lt artifactId gt jersey-container-servlet lt  artifactId gt       lt version gt 2 xx lt  version gt   lt  dependency gt   lt  -- if you are using Jersey client specific features without the server side -- gt   lt dependency gt       lt groupId gt org glassfish jersey core lt  groupId gt       lt artifactId gt jersey-client lt  artifactId gt       lt version gt 2 xx lt  version gt   lt  dependency gt    For Jersey 2 x you don t need to setup anything in your web xml  it is sufficient to supply a class similar to this   import javax ws rs ApplicationPath  import javax ws rs core Application    ApplicationPath  rest   public class ApplicationConfig extends Application        For more information  check the Jersey documentation   See also    java lang ClassNotFoundException  com sun jersey spi container servlet ServletContainer Jersey Services with Tomcat and Eclipse ClassNotFoundException when starting tomcat

Suppose you are usin Jersey 2 25 1  this worked for me - I am using Apache Tomcat web container        lt dependency gt           lt groupId gt org glassfish jersey core lt  groupId gt           lt artifactId gt jersey-server lt  artifactId gt           lt version gt 2 25 1 lt  version gt       lt  dependency gt       lt dependency gt           lt groupId gt org glassfish jersey containers lt  groupId gt           lt artifactId gt jersey-container-servlet lt  artifactId gt           lt version gt 2 25 1 lt  version gt       lt  dependency gt    NB  Replace version with the version you are using
