#147 Web, weather, movies - no go; MP3, shoutcast, photos OK

[Bob Sully]

I am running JavaHMO 2.0 on a Fedora Core 1 (fully
updated) system. I can play MP3s, display photos, and
stream ShoutCast from the server through the TiVo
machine without any problems, but simply get a blank
screen or the broken graphic (red X) when I try to
display a Web site or display weather or movie info.

I don't believe it's a firewall issue, as I'm not
seeing any unusual DROP/REJECTed packets in the
firewall logs. Also, since I can access ShoutCast
streams, it's clear that it can access the outside
Internet. The TiVo machine can't display a page from
the Apache server runnning on the same machine.
JavaHMO is running on the same box that the firewall is
running on...1600+ MHz Athlon with 768M of RAM. Java
is JRE 1.5.0.

I do get these warnings when I run the configuration
utility:

[root@firefox: /var/log]$ /usr/bin/javaHMOgui
log4j:WARN No appenders could be found for logger
(org.lnicholls.javahmo.gui.JavaHMO).
log4j:WARN Please initialize the log4j system properly.

I Googled this error message and didn't get much of
anything useful back.

Here's a snippet from the log file (/var/log/javaHMO.log)::

The "NO appenders" warning seems to indicate JavaHMO is not
configured correctly.

This is what I would expect the wrapper.conf to contain:

Well, I've checked the wrapper.conf file and it looks
good....I've attached it for your perusal. Thanks for the
come-back.

OK...now I'm getting a list of local theaters under
Movies...but still with red Xs. However, it's obvious it's
getting some data from the 'net. Same thing happens with
the weather plugin.
