webex/Java problems
 
(originally posted in "General", but I meant to post here)

I'm trying to use WebEx for distance education classes but I'm having some problems getting it to start up.

I have Suse 9.1 personal and I'm trying to start it up with Firefox 1.0.2.

When I click "Join Now" for the meeting, it doesn't take long for for a warning to pop up saying I need to enable Java. When I look at my Firefox options, it shows that I have "Enable Java" marked.

I have also had java errors with MATLAB, so I'm wondering if I have Java installed correctly. When I bring up the software install page in YAST, there is a long list of Java related packages, and I do have one installed (i wish i had the name with me), but all others seem to be development-related.

Any advice would be appreciated.

ps... i also should note that webex "requires" a 22kbps connection and I have only a measley dial-up (dsl may be on the way), but I don't think that is my problem.

When you bring up the consol and type
Code:
java
what appears?

Noted earlier on that SuSe had some *serious* troubles with Java (am a Java programmer)

well considering that most dialups these days are 56kbps 22kbps seems fine doesnt it.

Even so, I guess I just assumed I was below their requirements since when i bring up my data rate plot, I seem to recieve about 4-8kbps at most. If that is an idicator that my modem isn't working at it's best, that would be nice to know!

I will look into the console response, thanks!

Just to be on the safe side does it say KBps or Kbps as we are back at the old bit or byte problem

56 - 64 Kbps == ~8KBps

isn't it fun ...

on the other hand 22KBps would be bout bout 175Kbps (speak slower broadband)

lnebrown 09-21-2005 09:40 PM
it's kBps....

Thanks for pointing that out!

and to answer the "java" at the console prompt question, i get:

Code:
nebrown@linux:~> java
Usage: java [-options] class [args...]
          (to execute a class)
  or  java [-options] -jar jarfile [args...]
          (to execute a jar file)

where options include:
    -client      to select the "client" VM
    -server      to select the "server" VM
    -hotspot      is a synonym for the "client" VM  [deprecated]
                  The default VM is client.
....
....
.... and more stuff about options.

I would think this means I have Java, but why won't doesn't firefox like it?

Yes, correct, java is installed and also in your PATH (one of the common problems)

My educated guess is that the Fx does not have the plug-in installed or that the plug-in is at the wrong place.

Follow the instructions on this page, for installing Java Plug-in under Linux, basically it is only setting a link

Say you installed Java in /usr/java/j1.5

Then open your console, cd into your Fx plugins directory and there
Code:
ln -s /usr/java/j1.5/plugin/i386/ns610-gcc32/libjavaplugin_oji.so
But have a look on the web-page http://www.mozilla.org/support/firefox/faq#q2.2
and if memory serves, look in your rpm manager for firefox and java - could be that SuSe has a Firefox java plug-in
