what are the advantages that JWS offers by keeping Jars separate vs One-Jar?

问题

I am trying to launch One-Jar using JWS but it could not make it launch. Can anybody suggest me a good approach to make web start version of application from my two options --

1. Launch One-Jar using JWS

Have anyone tried this earlier? I am not getting success in this. Related Post.

2. Launch simple application JAR by specifying each jar in property that are being used in application.

I am looking a strong reason to avoid One-JAR because

1. We always need to keep updating JNLP if any JAR version updated or if we added a new JAR in our application.
2. We are already using One-Jar for our java-desktop version. so this same jar would be use for desktop as well as for web version.
3. what are the advantages that JWS offers by keeping Jars separate?
