Java Console for firefox

These rather cryptic command installs the java console addon for firefox.

$ cd /usr/lib/firefox-addons/extensions
$ sudo jar -xvf `find /usr/lib/jvm -name ffjcext.zip`

Maudio-1010LT and ubuntu 9.10

Initially I could get no sound with 9.10 after much research I managed to get a /usr/share/alsa/cards/ICE1712.conf that works!!

envy24control does not work out of the box I got this ,

Unable to read peaks: No such file or directory

Install the latest alsa see

I installed everything from source (this overwrites the ICE1712.conf . . . fix it again!)

Java Media Framework (JMF) and ubuntu 9.10

Download and installing JMF

Down load the JMF installation from here

The install instructions don't work! But you can extract like this.

unzip jmf-2_1_1e-linux-i586.bin

Testing

To use initialise go into bin and

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so ./jmfinit

All the commands need this prefix because JMF uses an older version of vl4. To test

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so ./jmstudio

If you get this error

Exception in thread "JavaSound PushThread" java.lang.IllegalArgumentException: amount of data to read does not represent an integral number of frames

You are probably using openjdk

update-java-alternatives -l
java-6-openjdk 1061 /usr/lib/jvm/java-6-openjdk
java-6-sun 63 /usr/lib/jvm/java-6-sun

Switch to the sun java

sudo update-java-alternatives -s java-6-sun
