Tomcat 7 does not scan annotations when using Jersey 2 - java

I have a Jersey 2 Maven project.

My project works fine when working locally. But it doesn't work anymore when i deploy it on my remote server.
So what happens is basically, that the WAR gets deployed correctly but there is really no error or warning in catalina.out. I get a 404 on every of my defined endpoints.
catalina.out:
Sep 14, 2015 2:03:00 PM org.apache.catalina.startup.HostConfig deployWAR

public class ApplicationResource extends ResourceConfig {
private static final Logger LOGGER = null;
public ApplicationResource() {
// Register resources and providers using package-scanning.
packages("com.api");
System.out.println("started");
register(MultiPartFeature.class);
// Register my custom provider - not needed if it's in my.package.
register(ResponseCorsFilter.class);
// Register an instance of LoggingFilter.
register(new LoggingFilter(LOGGER, true));
// Enable Tracing support.
property(ServerProperties.TRACING, "ALL");
}
}
What could be the problem? I developed on tomcat8 (but don't remember using something specifically) and deployed on tomcat7. Could this be a problem?
This endpoint should be reachable: http://54.228.220.152:8080/GLI_API/api/item
The other API works fine - so the server in general is working.
Also - if you don't have the final answer i would really appreciate it if you can point me to files/directories to look at since i don't get any error.


You may try to enable annotation scanning by setting this init parameter to your servlet:
<servlet>
...
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>com.yourproject.packageWhereYourResourcesAre</param-value>
</init-param>
...
</servlet>
Update
It seems you have compiled against Java 8, while Tomcat runs with Java 7? Try this:
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
You may also want to update your web.xml to 3.0:
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

Wildfly server running, but returning 404 error Not found no matter what I do

I followed a REST API | Web service tutorial on the web and got stuck midway. When I run the server it setups successfully, shows that its running at http://localhost:8080/ as well but as soon as I try to access different servlets, the page reloads and returns with 404 Error Not found. I tried downloading earlier versions of wildfly with no avail. The paths I tried were /demorest, /webapi, /myresources and they were used in conjunction as well.
What could be the problem?
package com.david.demorest;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;
#Path("myresource")
public class MyResource {
#GET
#Produces(MediaType.TEXT_PLAIN)
public String getIt() {
return "Got it!";
}
}

It's likely that the tutorial is written to deploy to Tomcat. Wildfly has everything you need for JaxRS built in.
To get started you will need three files. First, you need a class that extends javax.ws.rs.core.Application. It can be in any package you'd like:
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
#ApplicationPath("/rest")
public class RestApplicationConfig extends Application {
// intentionally empty
}
Next, you need your service. The one you show should work though I'd have my Path start with a forward slash like #Path("/myresource"). Lastly, you need a pom.xml that produces a war file. I haven't tested yours but I have one that looks like:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<artifactId>jaxrs-simple-sample</artifactId>
<groupId>com.hotjoe.jaxrs</groupId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
<properties>
<maven.compiler.source>11</maven.compiler.source>
<maven.compiler.target>11</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<failOnMissingWebXml>false</failOnMissingWebXml>
</properties>
<dependencies>
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>8.0.1</version>
<scope>provided</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.2</version>
</plugin>
</plugins>
</build>
</project>
That I just verified works. Once you have all of this you can produce a war file that can be dropped into $WILDFLY_HOME/standalone/deployments and Wildfly will run it. But you need to watch the URL. As defined in my pom.xml this will create a war file named jaxrs-simple-sample-1.0-SNAPSHOT.war and this file name becomes part of the URL. In this example, the URL to your service would be http://localhost:8080/jaxrs-simple-sample-1.0-SNAPSHOT/rest/myresource. The rest part of that comes from the #ApplicationPath defined. But the other part comes from the name of the war. If you don't like that, you can add one more Wildfly specific file:
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
<context-root>myapp</context-root>
</jboss-web>
This file, in a standard Maven environment, would be named jboss-web.xml and would be placed in src/main/webapp/WEB-INF. This would change the above URL to http://localhost:8080/myapp/rest/myresource.

Asynchronous Process not Working in javax.ws.rs.*(REST Client)

I demonstrate asynchronous process in REST API using javax(2.26 version). When I tried I got"A filter or servlet of the current chain does not support asynchronous operations." I don't know what to do with that. I tried many ways but doesn't work out.
The below is the resource file
Resource.java
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.container.AsyncResponse;
import javax.ws.rs.container.Suspended;
import javax.ws.rs.core.MediaType;
import com.jersey.rest.User;
#Path("/async")
public class AsynDemo {
#POST
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
public void asyncMethod(#Suspended final AsyncResponse response, User user) {
new Thread() {
public void run() {
response.resume(true);
}
}.start();
}
}

Could you help me to solve this? :)

Add <async-supported>true</async-supported> in web.xml servlet definition.
<servlet>

<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>

<load-on-startup>1</load-on-startup>

<servlet-mapping>
<servlet-name>Jersey jwt Application</servlet-name>
<url-pattern>/jwt/*</url-pattern>

it solved the issue.

I m building a web app and using apache poi for working on excel sheets. When I start the server I get the following exception. Thing is it used to work fine until i tried to build it and deploy in on heroku (but might be irrelevant).
Anybody has an idea??

Perhaps it was working on a Tomcat setup that had poi classes available on the classpath. In the new Heroku setup, perhaps you don't have those classes available with Tomcat 7 (I haven't thoroughly checked if poi classes come bundled with Tomcat 7).
The easiest thing you can do is to build a self-contained app by bundling the poi classes along with your app. This increase your app's size, but you get to control the poi library version. Of course, you can always copy the libraries to a defined folders (where you know Tomcat loads the classes from). See maven-shade-plugin for details.

Deploy JSP Webapplication on Tomcat7 (via OpenShift with GIT)

I have build a web appliation containing a Spring MVC project with a mysql database and a tomcat7 server. This is now published to GIT of OpenShift.
But starting the server takes only 160ms and I can clearly see nothing is being loaded really.
How do I do a real deployment and connect the Openshift Tomcat to my project?
I can code, but deployment-wise I am not a smart bulb.
My GIT repository looks like this:
What is wrong?

It seems that you have forgotten to add an openshift maven profile inside your pom.xml like bellow with proper maven-war-plugin configuration.
<profiles>
<profile>
<id>openshift</id>
<build>
<finalName>travel</finalName>
<plugins>
<plugin>
<artifactId>maven-war-plugin</artifactId>
<version>2.1.1</version>
<configuration>
<outputDirectory>webapps</outputDirectory>
<warName>ROOT</warName>
</configuration>
</plugin>
</plugins>
</build>
</profile>
</profiles>
Then your application structure seems unusual. Usually to build a WAR with maven you put your webapp content in src/main/webapp, your resources in src/main/resources your WAR specific classes in src/main/java.
Take a look at maven-war-plugin user guide here.
Finally, check these documentations that could help you to unterstand how to deploy your application to Tomcat with OpenShift:
Host and Run Your Java Tomcat Application for Free on OpenShift’s PaaS
Tomcat Application Hosting
If you follow properly steps described in these documentations, then any git push will trigger a build and application re-deployment to Tomcat
EDIT
As you have a build compilation issue now (Java 8 not supported), you should take a look at this answer: invalid target release 1.8

I have a JSP application on OpenShift Tomcat.
But all of my source code located in /src/main
Java src code in /src/main/java that means com.example.Main 's location is <APP_NAME>/src/main/java/com/example/Main.java
JSP src code in /src/main/webapp that means index.jsp 's location is <APP_NAME>/src/main/webapp/index.jsp

Have you actually performed a git commit and git push?
If so, can you dump the logs from git push.
