Issue
I need a REST Service to handle File uploads. I added the RESTEasy Multipart Provider dependency:
<!-- https://mvnrepository.com/artifact/org.jboss.resteasy/resteasy-multipart-provider -->
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-multipart-provider</artifactId>
<version>3.1.4.Final</version>
</dependency>
This somehow caused my other REST Services to stop working properly, and they now return errors:
<html>
<head>
<title>Error</title>
</head>
<body>Not Found</body>
</html>
or
<html>
<head>
<title>Error</title>
</head>
<body>HTTP method POST is not supported by this URL</body>
</html>
I read that this happens because the implementation of doGet() and doPost() are missing. I don't understand how simply adding this dependency affects my other webservices. Does it add a new Servlet ?
This is my Web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.1"

Solution
The version of the dependency was not the one my wildfly was using. I solved my problem by changing the version to the correct one (3.0.24.Final, which ships with WildFly 11 Final), and I changed the scope to provided:
<!-- Resteasy-multipart-provider -->
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-multipart-provider</artifactId>
<version>3.0.24.Final</version>
<scope>provided</scope>
</dependency>
