I have trying to learn RESTEasy using this repo:

https://github.com/dashorst/jaxrs-quickstart-resteasy

After cloning it, i run mvn clean package, and then I have tried

cd target and java -jar resteasy-quickstart-0.0.1-SNAPSHOT.war I got this error:

no main manifest attribute, in resteasy-quickstart-0.0.1-SNAPSHOT.war

I also tried directly run the test code in

cd target/test-classes

And run java Start, but I got this error: 

Error: A JNI error has occurred, please check your installation and try again

I am not using eclipse or intellij, I just want to launch the server from command line and visit the site from browser. I have searched several similar questions like Can't execute jar- file: "no main manifest attribute" but none of them works.

You have to deploy resteasy-quickstart-0.0.1-SNAPSHOT.war file into an running application server.

For example, you could start Jetty and copy the file .war into the webapps directory.

Step 1

Here how to download the Jetty server: https://www.eclipse.org/jetty/download.html

Step 2

After uncompressing the archive (zip or tar.gz), open a shell, enter the Jetty home and run:

./bin/jetty.sh start

You'll see the Jetty through the url

http://localhost:8080/

Step 3

Then copy your .war file into ./webapps directory

Your project will be available following the url

http://localhost:8080/resteasy-quickstart-0.0.1-SNAPSHOT/
