I started create a new java web application scalable, but is not working, since i got error
"503 Service Unavailable No server is available to handle this request".
Im using RESTful service
My code is:
TestClass
#Path("/test")
public class TestClass {
#GET
public String getName() {
return "John";
}
}

In my Haproxy.cfg, i have this line option httpchk GET /myApp
Anyone can help?
If you do not have something in your application listening on the root context (/) then the haproxy will see your application as being down. You either need to have something listen on the root context, or change the monitoring option to point to a url that is returning a 200 (success) when it is polled.
Did you change the httpchk GET / to the httpchk GET /myApp?
Even if you change your application to be deployed at /myApp, you still need something that gives a 200 success on that url.

After debugging for a few hours, I am seeking help to set up a REST API using Jersey in Java. I am using a Tomcat 6 server and the following is my file structure of the Mavin project:
On the right, the resource which I want to expose can be seen.
For the web.xml I have a file as follows:
<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container,

I can build the Maven project and start the server. However if I want to add resources to the Server by right-clicking on the server name and clicking on "Add or Remove..." I get a message that I cannot select any resources. I followed the adivce in this question: There are No resources that can be added or removed from the server but it did not help and I also do not get any error messages which could lead me. Any recommendation what I am doing wrong?
When I want to run the Resource on the server by selecting "Run As" and then "Run on Server" I get the following message: The selection cannot be run on the server.
You can't select this project because Tomcat 6 does not support Servlet 4.0 projects. Servlet 4.0 requires Tomcat 9.x, which itself requires Java 1.8. See the Tomcat documentation.
You can lower the facet version, but it makes far more sense to simply use the newer Tomcat version. Tomcat 6 is far past its end-of-life.
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">

</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.
I'm working on this simple project and have this problem:
HTTP Status 404 – Not Found
Type Status Report
Message /RestTestThree/myService/Calculator/
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Apache Tomcat/9.0.30
I use this setting: JDK 13, Eclipse 2019-12, Tomcat 9.
I tried different URLs and I hope this one is the correct one:
http://localhost:8080/RestTestThree/myService/Calculator/
I tried both model 3 and 4. Tried different dependencies and versions.
When trying to run this project, at some point the Tomcat even won't start, giving the error
Server Tomcat v9.0 Server at localhost failed to start.
My files are as follows.

I had the same problem. After downgrade java 13 to 11 all work perfect. Need convert project to 11 some.
I went over everything, even made some changes, fixed some problems but still the server sends back 404 even though tomcat itself is up and running. Following is what I did:

}
}
I'm sure I'm missing something but I just can't figure out what it is. When run as - running on server, eclipse opens this url: http://localhost:9090/Resty/ but I see 404. I tried adding more resty/ to the url and also /example (see code above) but all gives 404.
What am I missing?
you are using <url-pattern>/resty/*</url-pattern> in web.xml and using #Path("/resty") in class for class mapping, and use url http://localhost:9090/Resty/ that is wrong. you need to use <url-pattern>/*</url-pattern>. and url will be http://localhost:9090/resty/
you can also use anything into <url-pattern>/*</url-pattern> which you want but you need to use this pattern before controller path in url.
I followed the very basic tutorial found here example and cannot seem to get past the following error:
Error 500--Internal Server Error
java.lang.StackOverflowError

I have exhausted several hours searching the web and constructing new projects with no luck. I understand that the StackOverflowError is produced from bad recursion calls and infinite loops, however I can't see this as the case here.
My current dev stack is eclipse juno, m2e-wtp, weblogic 12c, Java EE 6 using JSF 2.1
I am hoping it is something simple like a missing dependency or weblogic plugin in my pom.xml. Any help would me MUCH appreciated.
UPDATE 1: If I export the war file using eclipse (Right click the project -> Export -> WAR file) then manually deploy it via the weblogic admin counsel the app works as expected. More specifically the version of eclipse is the one from oracle (oepe-12.1.1.2.1-juno-distro-win32-x86_64.zip).

Solved the problem! After adding JSF 2.1 in the pom.xml the JSF 2.1 checkbox was checked in project facets, however it did not add the faces-config.xml to the project. I simple created a new xml file named faces-config.xml under the webapp --> WEB-INF folder and added the following xml:
<?xml version='1.0' encoding='UTF-8'?>
<faces-config 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-facesconfig_2_1.xsd" version="2.1">
<application></application>
</faces-config>
I Hope this helps others!
