[Openjnlp-devel] Furher development of OpenJNLP

[<Jan...@tk...>]

Hi !

We're using OpenJNLP for updating our enterprise-software-clients.
We choosed OpenJNLP over WebStart because we can't pass command-line
arguments to WebStart, and we don't want sandbox-security.

Now in out production environment, we've got some problems, which I hope to
have fixed:
1. When a download is interrupted due to a network error, the downloaded
file was left currupted.
2. Version-based downloading was not implemented, but obviously prepared.
3. The JNLP-Spec doesn't address, how to deal with version-information if
the URL is a file://-URL. The implementation of Sun's FileURLConnection
just ignores parameters on file-URLs
(file://localhost/Q:/foo/bar?version-id=2.3 becomes Q:\foo\bar on Win32).

The solutions we chose were:
1. Downloading into a temporary file, copy to the cache after successful
download.
2. We implemented it ;-). But this required some massive code-changes,
mostly in CachedResouce.java. How should we deal with this, I'm frightened
of having to integrate out changes into the next OpenJNLP-Release. Another
issue is I used the jardiff.jar for patching the JarDiffs delivered by the
JNLPDownloadServlet. Are there any legal issues?
3. If version-information is provided with a file URL, the
naming-convention of the JNLPDownloadServlet is used so the file for the
above URL would be: Q:\foo\bar__V2.3
