Hey,  
I am connecting elastic apm with spring boot application, I am able to connect my application with .jar file, but now when I am trying it with .war file I am not able to do it due to the following errors.  
When I am running this command I am getting this error.

**java -javaagent:/home/abcd/Desktop/elastic-apm/apm-agent-attach-1.5.0/elastic-apm-agent.jar -war spring-mvc-example.war**  
getting this error.

> Unrecognized option: -war  
> Error: Could not create the Java Virtual Machine.  
> Error: A fatal exception has occurred. Program will exit.

And when I am running this command  
**java -javaagent:/home/abcd/Desktop/elastic-apm/apm-agent-attach-1.5.0/elastic-apm-agent.jar spring-mvc-example.war**

Getting this error

A `war` is something meant to be deployed in a Web Server like Tomcat for example (WAR mean Web ARchive). It is not meant to be run as a jar unless it has also an embedded `main` jar.
