RE: Spring MVC Portlet Deploy Error
Hi!
So, I've downloaded Liferay 7 CE bundled with Tomcat 8.
I've followed this reference to deploy a sample (https://dev.liferay.com/es/develop/reference/-/knowledge_base/7-0/spring-mvc-portlet)
When it's being deployed it throws this:
java.lang.ClassCastException: class com.liferay.portal.kernel.servlet.PortletServlet
Could someone please help me?

Agustin David LUzenti:
java.lang.ClassCastException: class com.liferay.portal.kernel.servlet.PortletServlet
Class cast issues are rarely that, they are actually indicators of class loader issues.
Like this one, for example, it looks like you have the servlet and/or portlet API jars in your WEB-INF/lib folder of the WAR. These would conflict with the global jars in Tomcat's lib and lib/ext folder, leading to class cast exceptions.
Thanks! I forgot some dependencies in my pom! Now it's working 
Hi Agustin.Seems like I'm facing a similar issue right now.
Could you describe, what exactly did you change in your project's dependencies back then?
Could you describe, what exactly did you change in your project's dependencies back then?
You're likely going to face two cases:
1. CNFE, or unresolved requirements from OSGi. These stem from *not* having a dependency packed into the WAR that needs to be satisfied before the WAR can start.
2. Class cast exceptions, class loader related exceptions, etc. These stem from having a dependency in your WAR that is also provided by Liferay. It's not this clean, because for some things (i.e. commons-lang) you can contain it in your WAR and it is not a problem. However, if you are mixing (intentionally or not) class instances from your WAR context and the Liferay context, this will cause you these kinds of exceptions. The solution here is to remove the dependency from the WAR (use provided scope for maven or compileOnly in gradle) and rely on the one Liferay can inject for you via the OSGi runtime.

Actually, my case looks a little bit different (don't now, maybe I even need to start a new thread).
I have a Spring app packed as WAR, which works fine on its own.
But when I deploy it on the server with javax.mail library deployed, it crashes with java.lang.ClassNotFoundException: com.liferay.portal.kernel.servlet.PortletServlet cannot be found exception. Moreover, if I delete javax.mail module manually, Spring app immediately starts app and works fine even after javax.mail module redeploy and server restart. But as soon as I deploy newer version of the Spring app, it starts all over again with deployment exceptions.
I have a Spring app packed as WAR, which works fine on its own.

There is a mail.jar in the global scope, wonder if that's interfering.
Instead of deploying a mail jar, try embedding into your war as a dependency.

It is required by another module, not war itself. Interfering with mail.jar is an interesting idea, though.
So embed it into the module that needs it, but don't deploy it into the container.
The only time you want to consider deploying a 3rd party jar as a module is if you are going to have multiple consumers of that jar. If you only have a single consumer, it can actually get in your way to have it as a module instead of just embedding.
