Tomcat 7 Gets Errors During Startup of Java Project

Tomcat 7 Gets Errors During Startup of Java Project - maven

I have a Java project which was working perfectly before. Now I'm getting the errors below. The server startup is successful but the services do not work.
Java version of the project is 8 and I use Tomcat 7 server.

Add CORSHandler to a camel-jetty component

I need to add the following CORSHandler to a camel-jetty component.
public class CORSHandler extends AbstractHandler
{
#Override
public void handle(String arg0, Request arg1, HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
System.out.println("GOT REQUEST!!!!!!!");
if(request.getMethod().equals("OPTIONS")){
System.out.println("CORSFilter HTTP Request BS: " + request.getMethod());
// Authorize (allow) all domains to consume the content
response.addHeader("Access-Control-Allow-Origin", "*");
response.addHeader("Access-Control-Allow-Methods","GET, OPTIONS, HEAD, PUT, POST");
response.addHeader("Access-Control-Allow-Headers","Authorization");
// For HTTP OPTIONS verb/method reply with ACCEPTED status code -- per CORS handshake
if (request.getMethod().equals("OPTIONS")) {
response.setStatus(HttpServletResponse.SC_ACCEPTED);
arg1.setHandled(true);
}
}
}
}
I'm trying the following way,
from("jetty:http://0.0.0.0:8082/proxy?disableStreamCache=true&matchOnUriPrefix=true&enableMultipartFilter=false&handlers=#corsHandler")
.to("jetty:http://localhost:8085/myWebApp/foo?bridgeEndpoint=true&throwExceptionOnFailure=false&traceEnabled=true")
.to("log:MyLogger?level=INFO&showAll=true");
Following is my camel-context.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:camel="http://camel.apache.org/schema/spring"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd">

<camelContext id="esbConsoleCamelContext" xmlns="http://camel.apache.org/schema/spring">
<routeBuilder ref="cloudServiceRoute"/>
</camelContext>
</beans>
I'm getting the following exception upon deployment.
Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint: jetty://http://0.0.0.0:8082/proxy?disableStreamCache=true&enableMultipartFilter=false&handlers=%23corsHandler&matchOnUriPrefix=true due to: No bean could be found in the registry for: corsHandler of type: java.lang.Object

Any info on how should I configure the CORSHandler for the camel-jetty component?

Is it even possible? both jsp, kotlin and maven?
Thanks!

The classes in your project are in the resources folder.
This is not where they should be - this folder is used only for resources.
Create a new folder, mark it as source root, and use that folder instead.

HTTP Status [500] - Servlet.init() when deploying war

I want to deploy war to tomcat8 but when I call url:
http://localhost:8080/SpringNew/tesget
get error:
HTTP Status [500] – [Internal Server Error]
javax.servlet.ServletException: Servlet.init() for servlet
[dispatchers] threw exception

before I deploy, I run the project with maven build usually, this url running. why not running after deploy?

Does anybody have any clue why this is happening?

We solved the problem by removing the folders that tomcat creates in the path /tomcat8/work/Catalina/localhost.
Reading #Jared answer here Why am I getting a NoClassDefFoundError in Java?
Usually this indicates that we previously attempted to load a class from the classpath, but it failed for some reason - now we're trying to use the class again (and thus need to load it, since it failed last time), but we're not even going to try to load it, because we failed loading it earlier
and regarding the fact that the work directory of tomcat is where tomcat writes any file that it needs during run time (for more info read here tomcat8 configuration reference)
This directory will be made visible to servlets in the web application by a servlet context attribute (of type java.io.File) named javax.servlet.context.tempdir as described in the Servlet Specification
, I believe that these two things correlate with each other

java.lang.IllegalStateException: Could not find backup for factory javax.faces.context.FacesContextFactory

I have a JSF Web application and since i'm using using an embedded databse, i wanted to use an embedded server, so i went with tomcat.
I found a main class with the code i need.
I executed the main class using eclipse and everything worked fine so i decided to build to the project to a jar to execute it from the command line, and this is where this exception came up
