REST giving 404

Question

Hi I am new to maven and am not able to run my project. its throwing 404 for the mapped resources.

            </configuration>
        </plugin>
    </plugins>
</build>


<properties>
    <jersey.version>2.16</jersey.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

I have 2 classes :

@ApplicationPath("webapi")
public class MyApp extends Application {

}

these are the errors I am getting. Couldn't figure out what is wrong. Java compiler level does not match the version of the installed Java project facet. JAX-RS (REST Web Services) 2.0 requires Java 1.6 or newer.
One or more constraints have not been satisfied.

I am using jdk 1.8.0_111 I tried to put that in maven and tried ${jdk.version} I tried [1.8.0_111) also its giving same error. Its loading the welcome page correctly but giving 404 to the resource URI. is there something wrong in pom.xml?

@Path("hello")
public class MyResource {

@GET
@Produces(MediaType.TEXT_PLAIN)
public String testMethod() {
    return "Hello World";
    }
}

for only 1.8 as compilance unit its not able to start tomcat.

did you try just `1.8` instead of `[1.8.0_111)`? does that work? — Naman, Dec 15 '16 at 18:51
Please share the entire stack trace as to which line of code or building what module results in > Caused by: java.util.zip.ZipException — Naman, Dec 15 '16 at 19:00
I deleted everything from .m2 folder and updated maven Now its not throwing error at 1.8 compilance but still getting 404. — Sumit Sagar, Dec 15 '16 at 19:09
Can you show your web.xml? Have you defined the servlet container with resource package on it? — notionquest, Dec 15 '16 at 19:10
@Sumitsagar I believe too many questions into one is not a good practice. Please try and decouple as you debug. — Naman, Dec 15 '16 at 19:12
Actually I dont know what is causing the 404 in web page. previously I thought might be maven error. but i fixed that but still getting 404. — Sumit Sagar, Dec 15 '16 at 19:35
it worked. I had the jars in the .m2 folder corrupted, I deleted there updated the project and it ran. Thank you ALL. — Sumit Sagar, Dec 15 '16 at 19:50

Post that if you see any exception, that needs to be resolved in the code.

Also make sure your jar file is not corrupted. If it's corrupted or not able to unzip, this error will occur. In such case try deleting the existing jar and build again.

if I change it to 1.8 the server is not starting. Getting the above error — Sumit Sagar, Dec 15 '16 at 18:55
