Java Web Start has supported Pack200 since it first appeared, but initially this feature required server-side cooperation and a certain amount of expertise to set up. When SUN introduced J2SE 6u10, Pack200 support became available without the need for special server support. Application designers can enable or disable this feature within JNLP files.

On slow connections Pack200 gives a significant performance boost in application startup time and download time.

WebStart is a power technology that hasn't realized its potential. Some of problems with JNLP are:

* Developer has to write server URI in JNLP file, so it is not possible to use same JNLP descriptor file in production and testing environment. Developer cannot just drop .jnlp file into server shared directory, he or she has to edit it. This problem could be solved if .jnlp file opened directly by web browser plugin (as for [[Java Applet|applets]]), or by introducing jnlp: URI scheme, so .jnlp file descriptor opened by URL like jnlp:http://my-site/app.jnlp. jnlp: URI scheme may be handled by JNLP handler.
