Add custom serializers to your webapp (optional)

If you want to use java's built in serialization nothing more has to be done. If you want to use a custom serialization strategy (e.g. because of better performance) this has to be deployed with your webapp so that they're available in WEB-INF/lib/.

As msm is available in maven central (under groupId de.javakaffee.msm) you can just pull it in using the dependency management of your build system. With maven you can use this dependency definition for the kryo-serializer:

<dependency>

    <groupId>de.javakaffee.msm</groupId>

    <artifactId>msm-kryo-serializer</artifactId>

    <version>1.9.7</version>

    <scope>runtime</scope>

</dependency>
