Re: [GeneX-dev] Rcluster issues..

Michael:

I think the answer to your problems with Rcluster might lie in the fact you have 
a NEW version of it. At PAG we had the same problems. Harry and I explored the 
OLD versions of Rcluster and found the only one that worked was the one last 
created by our consultant Andrew Dalke many moons ago. Actually, the new 
versions of Rcluster do not contain any new functionality. They were just 
recompiled. Apparently the Python/Java compiler isn't working the same way it 
did when Andrew was here. Another problem we have to look into. (It may be 
easier to simply recode the applet in regular Java, since most of the code is 
Java AWT syntax anyway.)

Michael, the correct OLD version of Rcluster should be on the PAG demo computer 
(now genebox.ncgr.org), but it is behind our firewall at the moment. Harry, can 
you find that jar file for Rcluster on genebox and send it to Michael? I can't 
log into genebox. I don't seem to have an account or its password is not what I 
expect. Could you make sure I can log into genebox while you're at it?

Michael, you also may have to turn off all Java security. I know this works on 
IE5. Sometimes it doesn't seem to be required, other times it does. I haven't 
had time to figure out what casues this difference in behavior. If you need help 
navigating through the IE5 Java options, give me a call and I'll walk you 
through it.

Meanwhile, as far as I can tell, there is no Java console for any version of 
Netscape I have. Java security options are under the menu option 
Edit/Preferences/Advanced.

Obviously, this later problem with avoiding applet security errors by opening up 
security holes in the browser is really serious. We can't have users truning off 
their Java security. We just haven't had time to address the problem. It 
probably requires digitally signing the app to fix the problem, but why bother 
now with that in the Python version, if we are just going to recode it in Java 
anyway?
