I found the error  I have a library that it was built using jdk 1 6  The Spring main controller and components are in this library  And how I use jdk 1 7  It does not find the classes built in 1 6    The solution was built all using  compiler compliance level  1 7  and  Generated  class files compatibility  1 6    Source compatibility  1 6    I setup this option in Eclipse   Preferences Java Compiler   Thanks everybody

I had this info message  No Spring WebApplicationInitializer types detected on classpath  while deploying a WAR with spring integration beans in WebLogic server  Actually  I could observe that the servlet URL returned 404 Not Found and beside that info message with a negative tone  No Spring    etc  in Server logs  nothing else was seemingly in error in my spring config  no build or deployment errors  no complaints  Indeed  I suspected that the beans xml  spring context XML  was actually not picked up at all and that was bound to the very specific organizing of artefacts in Oracle s jDeveloper  The solution is to play carefully with the  contributors  and  filters  for the WEB-INF classes category when you edit your deployment profile under the  deployment  topic in project properties   Precisely  I would advise to name your spring context by the jDeveloper default  beans xml  and place it side by side to the WEB-INF subdirectory itself  under your web Apllication source path  e g  like  lt    your project path  public html    Then in the WEB-INF classes category  when editing the deployment profile  your can check the Project HTML root directory in the  contributor  list  and then select the beans xml in filters  and then ensure your web xml features a context-param value like classpath beans xml   Once that was fixed  I was able to progress and after some more bean config changes and implementations  the message  No Spring WebApplicationInitializer types detected on classpath  came back  Actually  I did not notice when and why exactly it came back  This second time  I added a   public class HttpGatewayInit implements WebApplicationInitializer           which implements empty inherited methods  and the whole application works fine      If you feel that java EE development has been getting a bit too crazy with cascades of XML configuration files  some edited manually  others through wizards  intepreted by cascades of variant initializers  let me insist that I fully share your point

This is common error  make sure that your file war is built correctly  Just open  war file and check that your WebApplicationInitializer is there

lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-compiler-plugin lt  artifactId gt                 lt configuration gt           lt source gt 1 8 lt  source gt           lt target gt 1 8 lt  target gt       lt  configuration gt    lt  plugin gt    This is the important plugin that should be in pom xml  I spent my two days debugging and researching  This was the solution  This is Apache plugin to tell maven to use the the given Compiler

I had similar problem with Tomcat 8 embedded in java7 application    When I launched Tomcat in my application  it worked  But when I launched it through Maven for integration test purpose  I got this error    No Spring WebApplicationInitializer types detected on classpath     I fixed it by upgrading org apache tomcat embed tomcat-embed-  dependencies from version 8 0 29 to 8 0 47

[java] INFO: No Spring WebApplicationInitializer types detected on classpath
