Java Web Start & JNLP - Unofficial Web Start/JNLP FAQ started
Hi,
I started the Unofficial Web Start/JNLP FAQ page.
The Unofficial FAQ complements Sun's official Java Web Start FAQ page and aims to provide you with information that is not included on the
official page for whatever reason.
Your contributions are welcome even if you are not a multi national company.
Check it out at http://www.geocities.com/vamp201/jwsfaq.html

Hi,
I updated the Unofficial FAQ.
Here are the new entries:
* How to share cookies/sessions between Web Start apps and servlets?
* How can I control Web Start's update policy?
* Can I use Sun's J2EE Reference Implementation EJBs?
* How can I connect to Borland's AppServer?
Thanks for your contribution.
I will try to update it bi-weekly (that is, every second week) unless I'm on vacation (which will happen pretty soon).

In the future, how will new forum participants learn that the FAQ exists?

Hi,
I will post a message with new and updated entries bi-weekly (that is, every second week) so that new participants can learn that it exists.
Ideally, Sun would add a link to the Unofficial FAQ.
However, I guess this won't happen any time soon and I don't think that a petition would help.

Hi,
I added two new entries:
* How can I turn off the sandbox?
* Web Start returns a Bad MIME Type error.
What's wrong?
This is very likely the last update before my five week vactation.
I'll back in fall.

Any corrections, however, are more than welcome, please send them to vamp201@yahoo.com.

Hello Gerald,
thanks for updating that valuable list!
Some notes:
Regarding the topic "Can I use my own URLs for downloading JREs?"
This is what the spec tells.
Personally I have not tested if this feature works in practice.
What is very strange, and lets me suspect that this feature is not working correctly is, that such a server should have been implemented by Sun here:
http://java.sun.com/products/autodl/j2se
I tried to download a different JVM into Web Start
via this official update server, but it did never work.
(Anyone had more luck?)
Regarding "How can I debug apps under Web Start?"
The information given helps to run the Web Start application in debugging mode,
but it lacks information on how to attach a debugger.
The key is that
-Xrunjdwp:transport=dt_socket,server=y,address=8118
will make the running app wait for a socket connection to port 8118.
It is now possible to fire up the command line java debugger and to attach to the JVM via that port.
Let me give details in a later posting.
(I have to leave :)
Regards,
Marc

The link doesn't work.
I get a geocities error page
|
|
Sorry it says you exceeded the allotted data transfer.
Can you set up a second site (i.e.
A mirror) in case this continues to happen.
|
|
It is available again.
Guess there is a bandwidth/day limit.
Regards,

I have another entry candidate:
Launching the Java Web Start application manager from a web page
The Sun demo page uses an undocumented feature:
http://java.sun.com/products/javawebstart/apps/player.jnlp
If one click to such a link like above, which links to this player.jnlp file
<?xml version="1.0" encoding="utf-8"?>
<!-- Jump specific JNL file for launching the player -->
<player/>
the Web Start application manager will get launched from the browser.
I have not seen this player tag documented in the jnlp specs.
Regards,
Marc

Hi,
Marc: Thanks for your valuable corrections and new entries.
I will add them in the next couple of days.
I'm sorry that the Unofficial FAQ is from time to time unavailable because I hit my Geocities transfer limit.
If the Unofficial FAQ is currently unavailbe, please search for jnlp faq in www.google.com and use google's cached version.
I will try to find a solutions over the next couple of days.
I will create a pdf version for easy download and offline usage and I will move my large jars to a different site as they seem to eat up my Geocities monthly transfer limit pretty fast.

Please try again later.

The entry, " Does Web Start support Mozilla?" states that you have to configure the mime type manually.
Perhaps this is true on Linux or other platforms but not on Windows.
Once Java Web Start is installed on Windows you can use Mozilla to click on links and have them launch.
