how to run a war file in maven application?

Question

I'm trying to run a war file in a maven aplication.

Since I need the oauth2 b2c from azure I found this usefull code

I've never tried Spring before so I'm new about it

I tried to compile with mvn compile and JDK 1.7 as it says in github

but I got an error instead:

Cannot find symbol : Base64

Searching on internet I found it was supported by Jdk 1.8 + and by importing error so I did the import and that did the trick.

After that I did mvn package and it also did the package generating the war files and target folder.

I ran the war file java -jar azure-b2c-oauth2.war

But got this error:

Any help would be apreciate thanks!

you can't run war file with `java -jar azure-b2c-oauth2.war` command this command is used to run executable jar file. you need tomcat to run the war file. — Amit, May 25 '17 at 13:21

@AmitK putting the .war file inside of tomcat folder would be enough? — User100696, May 25 '17 at 14:28

below Command is not correct to run.

java -jar azure-b2c-oauth2.war

This only works for jar based packaging, If you choose to package your application as a war file you should refer to your server and IDE documentation.

Refer : http://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-running-your-application.html

refer for server deployment: https://www.mkyong.com/spring-boot/spring-boot-deploy-war-file-to-tomcat/

OR

you can build package spring boot as jar using below ,

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<!-- ... -->
<packaging>jar</packaging>
<!-- ... -->
</project>

and then use java -jar azure-b2c-oauth2.jar

Your POM.xml says WAR, either change that to Jar or use this code as is and package war and then use a server such as tomcat to unpack and run it.

You can only run jar files with java -jar filename but since your POM is set to war package, you create .war file
