working with files

Does not work within eclipse (likely due to the classpath) if you figure out why, please let me know!

Please use the embedded tomcat, run:

mvn clean package

then
​
 On Mac and Linux:
$ sh target/bin/webapp

On Windows:
C:/> target/bin/webapp.bat

Add new dependency to your pom.xml:

<dependency>
	<groupId>org.glassfish.jersey.media</groupId>
	<artifactId>jersey-media-multipart</artifactId>
	<version>2.14</version>
</dependency>


Add another init param to your servlet


<init-param>
	<param-name>jersey.config.server.provider.classnames</param-name>
	<param-value>org.glassfish.jersey.filter.LoggingFilter;org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
</init-param>
