[Jalview-discuss] Jalview applet compatibility issue

[Jim Procter]

Dear Vincent.

Thanks very much for contacting us. I recently heard about MACSE from an 
attendee of the Jalview course two weeks ago, and it is a nice 
coincidence that you have emailed, even more so in that you have found a 
problem with Jalview!

May I ask what OS you used to identify this problem ?  Also, could you 
verify that the 'Do I have java' link at http://www.java.com/ reports 
that Java is working ?  The reason I ask is that as far as I am aware, 
firefox 8 and chrome (practically all versions) require JRE1.6.

Do you find the same problems with the non embedded examples on 
http://www.jalview.org/examples/applets.html ?

Forgive me, but I am a little confused by this part of your email. If 
you wish to deploy the unpacked .class file set on your site, then you 
may simply unpack the jalviewApplet.jar into a directory using a 
standard ZIP archiving tool or java's own jartool. Normally, however, 
the JRE will be happy both ways, and the jar deployment method can 
result in slightly faster applet startup times.

On the other hand, the fact that you have mentioned this suggests 
something else might be happening. Are there some specific .class files 
that cannot be located in the jalviewApplet.jar, for which you are 
seeing 'Class Not Found' exceptions ?

Jim.

ps. my question regarding .class files excludes requests in your 
server's log for the SmarterJmolAdapter.class, which was mentioned in 
this previous 
thread:http://www.jalview.org/pipermail/jalview-discuss/2011-December/000729.html 
and can be solved by including the jmol applet jar at 
http://www.jalview.org/examples/JmolApplet-12.1.13.jar on the classpath.
