Tomcat throws exception
java.lang.ClassNotFoundException: com.web.servlets.SearchServiceServlet every time i try to access my servlet.
The servlets is in the correct package structure:
I defined my servlet in the web.xml:

The servlet class:
public class SearchServiceServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**

*/
public SearchServiceServlet() {
super();
// TODO Auto-generated constructor stub
}
/**

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

String first_name = request.getParameter("first_name");
String last_name = request.getParameter("last_name");
int age = Integer.valueOf( request.getParameter("age") );
String pet_name = request.getParameter("pet_Name");
String pet_type = request.getParameter("pet_type");
int rating = Integer.valueOf(request.getParameter("rating"));
int experience = Integer.valueOf(request.getParameter("experience"));
System.out.println("First name = "+first_name+",last name = "+last_name+",age = "+age+",pet's name = "+pet_name+",pet's type = "+pet_type+",rating = "+rating+",experience = "+experience);
}
/**

*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}
}
Could it be that eclipse doesn't properly generate classes?If yes,how can i test this?Because a simple POJO with main method works fine.
Also,here is the full exception and what the tomcat prints when i start the application:

P.S The class is in the right package :package com.web.servlets;
Try specifying the package in your class file.
package com.web.servlets;
java.lang.ClassNotFoundException Exception is thrown when the ClassLoader cannot find the specified class.
You have:
<servlet-class>com.web.servlets.SearchServiceServlet</servlet-class>
That means you have a package: com.web.servlets where the class SearchServiceServlet is located.
In case you have a Maven project you should have scr/main/java/%yourpackagename%/yourClass
In case it is a simple web-project then it should be like src/yourpackagename/yourClass.
The problem got fixed after the restart of eclipse...Though there is another problem. Whenever i save the servlets class,after changing it,it doesn't see the new class,but uses the previous version of it.What's the problem here?

I have a test listener which i created for learning purposes. It was working fine and i was trying to learn JSTL and added the dependent jar to build path and also pasted them under WEB-INF/lib directory of my project, i also did a maven update because my JSTL was not working. Now when i try to run tomcat and access through browser i get below error
Below is my project directory and tomcat logs from console.

I was writing a programme to test ServletContainerInitializer.the problem is ServletContainerInitializer itself works properly and ServletContainerInitializer.onStartup is called "ssd" is printed however the ServletContext.addServlet does not register my servlet and hence init method is not called. please check the log bellow

this code solved the above problem for me
PS: Don't forget to add META-INF/services/javax.servlet.ServletContainerInitializer
I have already looked at many tutorials, but I can't get my simple JAX-RS application to work. Tomcat always returns Error 404.
The Application to get Classes:
package api;
import java.util.HashSet;
import java.util.Set;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
#ApplicationPath("/resources")
public class MyApplication extends Application {
// All request scoped resources and providers
#Override
public Set<Class<?>> getClasses() {
Set<Class<?>> classes = new HashSet<>();
classes.add(AuthenticationEndpoint.class);
return classes;
}
}
My JAX-RS file:
package api;
#Path("/hello")
public class AuthenticationEndpoint {
#GET
public Response getUser() {
return Response.status(200).entity("getUser is called").build();
}
}

I changed from Windows to Ubuntu 17.04 and now I get an Error when I start the webapp on a Tomcat 8.0.36 via Eclipse Neon.3 Release (4.6.3).
java.lang.ClassCircularityError: ch/qos/logback/core/spi/FilterReply
The project is build via M2E has AspectJ in it.

It work's under Windows Eclipse with almost same settings and installation.
Also it works when I mvn clean package (default ubuntu maven installation not eclipse one) and deployed it manually to the default Tomcat installation of Ubuntu.
I already changed my eclipse version to Oxygen and got the same problem.
I tried to change the versions of the dependencies too - same result.
I have debuged the code to a "ServletContextListener" that tries to get a JDNI object:

// ....
#Override
public void contextInitialized(final ServletContextEvent sce) {
new LogRecord(Level.FINEST, "Ensure class is loaded!");
// Prepare logging context
final LoggerContext context = (LoggerContext) LoggerFactory.getILoggerFactory();
context.reset();
// setup JUL to SLF4J log bridging
SLF4JBridgeHandler.removeHandlersForRootLogger();
SLF4JBridgeHandler.install();
final LevelChangePropagator levelChangePropagator = new LevelChangePropagator();
levelChangePropagator.setResetJUL(true);
levelChangePropagator.setContext(context);
levelChangePropagator.start();
context.addListener(levelChangePropagator);
// Load context values
String contextPath = sce.getServletContext().getContextPath().replaceAll("[^0-9a-zA-Z-_]", "");
if(contextPath.length() == 0){
contextPath = "ROOT";
}
context.putProperty("appName", contextPath);
final Boolean isProductiveVal = (Boolean) getJNDI(IS_PRODUCTIVE_JNDI);
// .....
private static Object getJNDI(final String jndiPath) {
try {
final Context initialContext = new InitialContext(); // << This line crashes
return initialContext.lookup(jndiPath);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
I have no clue what I could try to fix it. And also im not fully understand the problem. Tomcat tries to load a Class that reference it self?!
Does some one have a clue what I could check?
Full stack of Tomcat start.

I changed to the Tomcat8 installation that I used in windows.
And it finally worked (I didn't know what the previous Head of did there).
The only difference I can see instantly is that it used Log4j also on Tomcat side. Maybe thats the difference. Sorry if someone else also have this problem and no solution.
When I try to load servlet in my eclipse neon, it gives me "Error instantiating servlet class com.Test" error stating that "The server encountered an internal error that prevented it from fulfilling this request." I can load .jsp page successfully but while trying to load servlet page it gives me following error in eclipse borwser.
and console generates following error.
