Is it possible to create a WAR file using the Java JRE?

Question

Using the Java JDK you can use the jar command to create a war file:

jar -cvf /tmp/mywar.war *

There is a way to work with .jar files with the Java JRE but can you create jar or war files with it?

/path_to_java/java -jar ???

Answer 1

Can you create jar or war files with the JRE?

No. The JRE does not ship with jar.exe.

In order to create jar or war files you need to install the JDK.
