I create a connection springstudent: with user spring student. Besides create a database with table on my workbench.
I would like to connect my eclipse project on my database. So I write the code and add a library.
My steps:
Download apache tomcat
Create web-dynamic project. Create a servlet Add library
my-sql-8.0.12
Java compiler, Java built path, Project Facest have the same version
I try to run doing both of the above settings: Server Right Click
priorities : workspace metadata Server Right Click priorities :
local
Delete and add the server(Window->Show Servers...) Check project
facets->runtime apache clicked Clean project Clean server
Delete and import project again.

Simply right-click on your servlet and choose Run As > Run on Server.

HTTP status 404 error when running cloned project from github on Tomcat 9.0

I have created a simple spring mvc web app and after successfully running it on the server I pushed it on github. Later I cloned this project and have imported it as a maven project as shown below (now it is already imported)
Now I am trying to run it but unfortunately I get HTTP Status 404 error:

Logback ClassCircularityError

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.
Uses following SLF4J Dependencies:
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.7</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jul-to-slf4j</artifactId>
<version>1.7.21</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.7.21</version>
</dependency>
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:
import java.net.URL;
import java.util.logging.Level;
import java.util.logging.LogRecord;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import org.slf4j.LoggerFactory;
import org.slf4j.bridge.SLF4JBridgeHandler;
import ch.qos.logback.classic.LoggerContext;
import ch.qos.logback.classic.joran.JoranConfigurator;
import ch.qos.logback.classic.jul.LevelChangePropagator;
import ch.qos.logback.core.util.StatusPrinter;
// ....
#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.

Unable to start tomcat 8.0.39

I am using Eclipse Mars IDE, JRE 1.8.0_51, and Tomcat 8.0.39. Is there any compatibility issue? Please suggest.
Server Tomcat v8.0 Server at localhost was unable to start within 45
seconds. If the server requires more time, try increasing the timeout
in the server editor.
I have also tried increasing the timeouts, but it didn't work.

What am I missing here? Any help will be appreciated.

I am pretty sure you are calling the root path of the server (e.g. localhost:8080/), right?
Eclipse deploys WebApplication in a context path with your projects name. The working path should be localhost:8080/<yourProjectName>/
You can change this behavior by opening the project settings -> Web Project Settings -> Context root.
Edit: since your only endpoint is /users you have to call localhost:8080/<yourProjectName>/users
