ServletContainerInitializer vs ServletContextListener

Question

I\'m trying to register a servlet using servletContainerInitializer but it doesn\'t seem to work, Maybe it\'s my code (kindly review it), but I came to wonder about the diff

Answer 1

Check if you have configured the ServletContainerInitializer propertly. The ServletContainerInitializer class name should be configured inside a file:

META-INF/services/javax.servlet.ServletContainerInitializer

The file should contain just the class name. For Ex in your case it should look like:

com.marmoush.javaexamples.nullhaus.servlet.MyInit

The file (META-INF/services/javax.servlet.ServletContainerInitializer) can be bundled in a library JAR in WEB-INF/lib.

Here is any example which explains.
