Java Reference
In-Depth Information
Regarding JNLP technology, two technical limitations need to be explicitly mentioned:
•JNLP Clients can communicate with their deployment servers only through a Web con-
nection. No communication protocols other than HTTP are supported.
• Only J2SE applications can be deployed with JNLP.
When such requirements cannot be matched, other deployment solutions should be investi-
gated. In particular, when no Web connection (that is, the HTTP protocol) is available, only ad-
hoc deployment options (see the example in Chapter 6 or the whole Chapter 7) or some
third-party deployment tools are left. A careful use of the JNLP technology can reduce the end-
user burden to the minimum (the so-called “one-click” installations).
3. Implement the Planned Deployment Circuit
See Chapter 4 for more details. For JNLP-specific advice, Chapter 13, “A Complete Example,”
provides a recapping, practical discussion.
