In my prototype projects, I work on implementing very simple REST service - both server (backend) and client that in fact is server too (frontend). Backend server works fine, but with client I encountered very, very strange problem. In Eclipse I have project "frontend" that has this bean called FrontEndPageBean.java:
package org.mader.demo.frontend;
import javax.faces.bean.*;
import javax.ws.rs.core.*;
/** Bean to show off frontend handling of REST. */
#ManagedBean
public class FrontEndPageBean
{
/**
* Resolve data from backend through REST service.
* #return Data as text.
*/
public String getRestData()
{ // Retrieve RESTful service using client API from JAX-RS 2.0
ResteasyClient client = new ResteasyClientBuilder().build();
ResteasyWebTarget target = client.target("http://127.0.0.1:8080/backend/rest/data/1");
Response response = target.request().get();
// Read output in string format
String value = response.readEntity(String.class);
System.out.println(value);
response.close();
return value;
}
}
It is called in home.xhtml like that:
Text resolved by REST from backend: #{frontEndPageBean.restData}
This is my pom:

Problem is that Eclipse does not recognize ResteasyClientBuilder, ResteasyClient nor ResteasyWebTarget. In tooltip it reads "ResteasyClient cannot be resolved to a type". No import options visible. It does not compile. It Just Does Not Work(TM).
According to various pages about consuming REST, ResteasyClient client = new ResteasyClientBuilder().build(); is kosher way. Only thing that I can think up is that there is something to add to POM, some missing dependency. Visit to https://mvnrepository.com/artifact/org.jboss.spec/jboss-javaee-all-7.0/1.0.0.Final does not help much, nor checking code of ResteasyClient - it looks like it should be already covered. Surely I missed something...
Environment: Java 1.7, Eclipse Kepler, Wildfly 8.0
Indeed, entries in POM were missing.
I needed to add other entries like that:
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-client</artifactId>
<version>3.0.6.Final</version>
<scope>provided</scope>
</dependency>
Note fully specified version and scope still being "provided".
I lost a lot of time chasing shadows. Lack of directly specified org.jboss.resteasy:resteasy-client etc in http://mvnrepository.com/artifact/org.jboss.spec/jboss-javaee-7.0/1.0.0.Final was surefire way to put me on wrong track.

Am using JBOSS EAP-7.3.0
java 9
If we assume the "javax" dependency which is currently called "jakarta" is the one to be used it with it's latest version it didn't solve the problem. Feels like no matter what version of javax i add it won't work!!!

Any idea thanks in advance!!!
You're using version 4.0.0 of JAXB, which is too new since in version 3.0 classes were moved from javax.xml.* to the new jakarta.xml.* packages.
Try version 2.3.0. You may also want to take a look at this comprehensive answer.
Since Vaadin 14 was released this Tuesday, I already tried using it in my Spring-boot web application. Including the dependencies in my pom.xml works fine.
Running the application works fine as well. However, as soon as I connect to the localhost via my browser I get the following message:
2019-07-05 13:46:33.743 WARN 7812 --- [nio-8080-exec-1] c.v.f.s.DefaultDeploymentConfiguration :
====================================================================
Vaadin is running in DEBUG MODE.
Add productionMode=true to web.xml to disable debug features.

2019-07-05 13:46:33.744 WARN 7812 --- [nio-8080-exec-1] c.v.f.s.DefaultDeploymentConfiguration :
====================================================================
Running in Vaadin 13 (Flow 1) compatibility mode.
This mode uses webjars/Bower for client side dependency management and HTML imports for dependency loading.
The default mode in Vaadin 14+ (Flow 2+) is based on npm for dependency management and JavaScript modules for dependency inclusion.
See http://vaadin.com/docs for more information.
====================================================================
As mentioned in the error, apparently Vaadin 14 is not running properly and it is setting back to the Vaadin 13 compatiblity mode.
I am now wondering if this has something to do with my code or with the version of my dependencies. How can I check/find out why the application resets to Vaadin 13 compatibility mode? And is there a way to run the application stable on the new Vaadin 14?
My pom.xml and my code, which is just the simple starter button that sends a click message are included below.
I have already tried disabling debug mode for Vaadin by changing the application properties. Sadly this did not work at all.

You should add vaadin-maven-plugin with prepare-frontend and build-frontend goals to your pom.xml.
<plugin>
<groupId>com.vaadin</groupId>

By default in project that was created with Vaadin 10-13 when updating the version to 14.x.x it will run in compatibility mode and everything should work as before. The warning you see is not an error, just an explanation of which mode is being used and it's expected for existing project that have the Vaadin version changed to 14.x.x
If you want to upgrade to the new mode based on npm for client-side dependency management and JavaScript modules for dependency inclusion take a look at the Vaadin 14 migration guide.
I have been struggling with this for about a week and nothing I have seen on SO has worked for me. I have a REST API built on Spring Boot that I am trying to deploy to the Google App Engine. Running locally is fine and when I run it on the GAE emulator it works fine as well; however, once I deploy using mvn appengine:deploy I get a successful build but when trying the endpoints I only get a 502. I'm not sure where the logs are so this is really kicking my butt.

My application class is a simple annotated #SpringBootApplication class. I have 2 controllers with annotation of #RestController and simple #RequestMapping methods. One of the REST controllers is for the /_ah/health endpoint that returns 200 since one post mentioned constant restarts being triggered by the lack of a healthcheck endpoint.
I have a simple application.yml for my value injections and created an app.yaml file placed in src/main/appengine
runtime: java
env: flexible
threadsafe: true
manual_scaling:
instances: 1
handlers:
- url: /.*
script: this field is required, but ignored
runtime_config:
jdk: openjdk8
I am at a complete loss on this. It is my first GAE deployment with hopefully more to go. (I also am not using Docker yet since I am on a Windows 10 machine that breaks when I load Docker on it.)

I did notice that I had forgotten to put my project id under the maven plugin. Once I did that I got errors about not finding the app.yaml. I realized that since I am using a flexible environment, I did not need the appengine-web.xml and I had my file misnamed as app.yml rather than app.yaml. I updated my question with this and I am still getting a 502 after a successful deployment.
I realized my trial period with GAE included tech support so I contacted them. The asked for my pom and app.yaml. Their response was to add the following to my app.yaml "Since Java is known for consuming high memory usage, there is an overhead process consumed more than the approximate 0.4GB value"
resources:
cpu: 2
memory_gb: 2.3
disk_size_gb: 10
volumes:
- name: ramdisk1
volume_type: tmpfs
size_gb: 0.5
They also provided this link for reference: https://cloud.google.com/appengine/docs/flexible/java/configuring-your-app-with-app-yaml#resource-settings
Once I did this, my application started working just fine.
EDIT
If you have a simple application, set cpu:1 since you get billed on CPU hours and your daily quota is 28 and with 2 CPUs you end up with 48 CPU hours. I burned through the free $300 credit in 1 month because their tutorials setup a RDB ($80) that doesn't get used and doesn't show to kill the project. Also make sure when deploying something new you delete the old versions or you will be charged for every version that is up.
I was following an example online but when I use the certain function request.getServletContext().getServletRegistrations(). It does not recognize this function
// Check the target of the request is a servlet?
private boolean needJDBC(HttpServletRequest request) {
System.out.println("JDBC Filter");
String servletPath = request.getServletPath();
// => /abc/mnp
String pathInfo = request.getPathInfo();
String urlPattern = servletPath;
if (pathInfo != null) {
// => /spath/*
urlPattern = servletPath + "/*";
}
// Key: servletName.
// Value: ServletRegistration
Map<String, ? extends ServletRegistration> servletRegistrations = request.getServletContext()
.getServletRegistrations();
// Collection of all servlet in your webapp.
Collection<? extends ServletRegistration> values = servletRegistrations.values();
for (ServletRegistration sr : values) {
Collection<String> mappings = sr.getMappings();
if (mappings.contains(urlPattern)) {
return true;
}
}
return false;
}
When I use this same function in a regular dynamic web project it works fine with no errors, but using maven these same methods are undefined. I tried to change the
request.getServletContext().getServletRegistrations();
to
request.getSession().getServletContext().getServletRegistrations();
I recognized the getSession.getServletContext(), but it then doesn't recognize the getServletRegistrations(). I figured it might've been a dependencies problem so I added several dependencies to my pom.xml

Solution
Replace :
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
with
</dependency>
</groupId>`org.mortbay`.jetty</groupId>
</artifactId>servlet-api</artifactId>
</version>3.0.20100224</version>
</dependency>
Differenct between org.mortbay.jetty:servlet-api-2.5:6.1.5 and javax.servlet.jsp:servlet-api:2.1
Jetty has a long and colorful history with jsp, having no jsp implementation of our own we have leveraged other implementations often, judging by the version numbers your looking at those are very old versions where we were maintaining patches on top of the glassfish jsp implementation. I think it was a patch for supporting logging in jetty and then a bug fix or three.
Now a days we have been using the jsp artifacts from the java.net project which was spun out from glassfish a while back. However that doesn't seem to be tracking bug fixes very regularly either so we are kicking around trying the jasper implementation in tomcat.
Back on your question, the jsp-api artifacts are typically just repackaged artifacts since the api doesn't change frequently. We historically rebundled them to keep them paired with the patched implementation.
Now, you are obviously using a jetty-6 setup since your still using org.mortbay packaging but jetty6 and jetty7 are both servlet-api 2.5 so you might be able to get away with using the jetty7 jsp setup, we have a handy pom that declares these artifacts here:
http://central.maven.org/maven2/org/eclipse/jetty/jetty-jsp/7.6.5.v20120716/jetty-jsp-7.6.5.v20120716.pom
These are glassfish bundles as well, repackaged and made into osgi bundles in the process so they can be used with jetty in osgi environments....they ought to work normally though, we package them in our jetty7 distributions.
I am fairly new to Wildfly and some parts of Java EE.
I have a rest service using RestEasy running on wildfly. My 'User' entity has an 'AccessToken' entity. Ideally, i'd like to be able to send the User entity as a JSON without it also sending the access token.
I did some research and found I should be able to use #JsonIgnore for exactly this. However, this annotation isn't available - probably a mistake in my POM.
If I understand correctly, Wildfly uses Jackson so the annotations should be 'provided'. I used a "bom" and what I thought was all of the provided parts, but I'm missing something?
Here is my pom.xml which originated from the quickstart through IntelliJ:

I did try adding:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.6.4</version>
</dependency>
This lets me use #JsonIgnore but then it still shows this field in the JSON returned to the client. I think perhaps my wildfly is using an older version of jackson (1.x) rather than 2? (This gives me that impression: JsonIgnoreProperties not working)
Annotation #JsonIgnore is a part of Jackson annotation jar.
To include it, use following dependency in your pom file.
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.6.4</version>
