I am new to Maven. I am trying to build a web project using maven and eclipse kepler. But after I run maven build with clean install the .xhtml files are not inside the web-inf folder, which is ultimately giving resource not found error

when I am invoking maven build with clean install the target folder is like below
target folder structure
Deployment assembly -->
src/main/java -->WEB-INF/classes
src/main/resources -->WEB-INF/classes
src/main/webapp -->WEB-INF/classes
Now when I run the project from Tomcat (right click -->run as --> run on server) it is showing "resource not available" error
First try a maven - update project, then clean and build your app again.
I do not see deployment descriptor in your project structure. Check in Project Facets, if you have marked Dynamic Web module.

I am trying to play around with Eclipse/Java and I am making a Dynamic Web Project in Eclipse. I have followed tutorials online and looked at several other Stackoverflow posts, but i'm still having the same problem.
When I run my server and try to hit my endpoint /test, I get a 404 error. Here is my code:
My Java Class:
package TestPackage;
import javax.ws.rs.Path;
import javax.ws.rs.GET;
#Path("/test")
public class Test {
#GET
public String Hello() {
return "hello";
}
}

I read that if you're using Jersey 2.+, you wouldn't have to fiddle around with your web.xml, so it's the standard format:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">

<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
</web-app>
So when I try to call http://localhost:8080/RestDemo/test, I get a 404 error. Any idea what's going on?
In Servlet 2.5 environment, you have to explicitly declare the Jersey container Servlet in your Web application's web.xml deployment descriptor file.
As per https://jersey.java.net/documentation/latest/user-guide.html#deployment.servlet
Example 4.10. Hooking up Jersey as a Servlet
<web-app>
<servlet>
<servlet-name>MyApplication</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
...
</init-param>
</servlet>
...
<servlet-mapping>
<servlet-name>MyApplication</servlet-name>
<url-pattern>/myApp/*</url-pattern>
</servlet-mapping>
...
</web-app>
started with this example: https://www.tutorialspoint.com/jsf/jsf_ajax.htm
eclipse does not like the .xhtml file provided with it, i used this:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:composite="http://java.sun.com/jsf/composite">
<h:head>
<title>JSF tutorial</title>
</h:head>
<h:body>
<h2>Ajax Example</h2>
<h:form>
<h:inputText id="inputName" value="#{userData.name}"></h:inputText>
<h:commandButton value="Show Message">
<f:ajax execute="inputName" render="outputMessage" />
</h:commandButton>
<h2><h:outputText id="outputMessage"
value="#{userData.welcomeMessage !=null ?
userData.welcomeMessage : ''}"
/></h2>
</h:form>
</h:body>
</html>
apparently the doctype wasnt right.
and of course the UserData from the tutorial. when running the project on tomcat 9 i can see the title and h2 heading, but no button or input field.
why is that?
i actually asked this question on serverfault, but since it was closed there i reposted it here. i hope that is ok.
somebody answered on serverfault and after that i did change my pom.xml to this:
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">

and did run "maven clean install" on the command line in the project directory.
after downloading a lot of smaller files it said if finished.
yet the webpage does not change, theres nothing on it besides the title and one heading.

so what did i miss to get this simple example running?
i did never find out what was wrong with this, but for readers of this post the ajaxguessnumber example from the java ee tutorials runs without a hitch in netbeans.
Also this tutorial:
http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/HomeWebsocket/WebsocketHome.html#overview
is great for getting into jsf2 / websockets.
I am trying to deploy my first rest application using jersey 2.17.
I am using Maven, GlassFish 3.1.2.2 for deployment.
Application runs in eclipse (tomcat), but gives following error when deploying through glassfish admin console.
Error occurred during deployment: Exception while loading the app :
java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.apache.catalina.LifecycleException:
java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map;.
Please see server.log for more details.

Ok looked at your issue. The External Glassfish v 3.1.2.2 that you are using is JAVA-EE 6 compatible. And the one through which you are running your app in eclipse is JAVA-EE 7 compatible.
Have a look at both the java docs:
Application class Java Doc for EE6
Application class Java Doc for EE7
You will see that the getProperties method got introduced in JAVA-EE 7.
Simply upgrade to glassfish version-4.x that is compatible with JAVA-EE 7. Assuming nothing else breaks should be good.
In my pom.xml, I have the following profile :
<profile>
<id>local</id>
<build>
<finalName>webProject</finalName>
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<path>/</path>
<contextReloadable>true</contextReloadable>
</configuration>
</plugin>
</plugins>
</build>
</profile>
I am running tomcat with the following command from my command line:
mvn clean tomcat7:run -Plocal
Everything works great except when I edit and save my java files (using intellij) nothing happens. The app doesn't reload at all. I have tried waiting and refreshing, but nothing has worked.
Any ideas?
Here is my web.xml
<web-app xmlns="http://java.sun.com/xml/ns/javaee"

Well it was a simple fix. Ill share it if anyone has the same problem. The problem was Intellij was not compiling the java files.
To get this to work, I had to go Build->Compile... (ctrl+Shift+F9).
Or, you can go to File ->Settings->Compiler->make project automatically and Intellij will do it automatically.
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
at weblogic.servlet.internal.ServletResponseImpl.addHeader(ServletResponseImpl.java:567)

at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)
at javax.servlet.http.HttpServletResponseWrapper.addHeader(HttpServletResponseWrapper.java:200)
Pressing shift + F5 a couple times I can generate a slightly different stacktrace as follows:

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).
(Answered in a question edit. Converted to a community wiki answer. See Question with no answers, but issue solved in the comments (or extended in chat) )
The OP wrote:
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"

I Hope this helps others!
