Huawei E3131 Modem on Ubuntu 10.04

Hello, am using an E3131 Huawei usb modem. I installed the mod-switch as advised. I ran
$ lsusb | grep 12d1
I get the output below
Bus 002 Device 005: ID 12d1:14fe Huawei Technologies Co., Ltd.

here is the list files in
$ ls /etc/udev/rules.d/
15-huawei-155x.rules
31-huawei-e3131.rules

I started the udev service.
Unfortunately, the e3131 modem does not perform. I made configurations for the APN, but no change whatsoever.

Would you possibly correct me?
Thanking you, Simon.

Running a midlet on command line interface

Thought of testing a mobile J2me app on your device before deployment? It can be done on your machine.

Make sure the wireless tool kit is installed.
Navigate to the bin directory via command line.
$ runmidlet your_midlet_name.jad

How to set up openxdata mobile client emulator to work with the Server-side development environment

Hi , this was inspired by the thread at openxdata developer discussion group.
I got through some steps to get the mobile client's code of the
emulator work with a server-side code in development mode.
Here are the chronicles.

1. Set up the mobile code(used 1.2.2 from the branch) as indicated on
the link https://trac.openxdata.org/wiki/MobileSetup
2. define download and upload urls as http://localhost:8888/mpsubmit
3. If using server-side code v1.2, you will want to throw the protocal
jars into the admin project . Put those jars into the folder admin/war/
protocal-jars
4. Run your mobile code through ant's tasks as outlined in the link in
step #1.
5. Run the server-side with mvn gwt:run, ofcourse from the admin
project on commandline.

Given the above steps, I pulled a list of studies on the emulator.
Don't hesitate to get back incase of any problems.


Cheers,
Simon.

A feel of GXT

 The link above gave me a practical exposure to the rich features of GXT. I have used them to develop an internet application.


It has beautiful code snippets.

How can I serve ruby and php on same apache machine?

Hi, I was caught up in between issues of deploying a ruby app behind an apache server, while allowing others like PHP to continue running normally. Here is the set of steps that worked for me.

-Ensure Phusion Passenger is installed and configured in apache.If you don't have them, run these two commands to install passenger and configure it automatically

             $ sudo gem install passenger
             $ sudo passenger-install-apache2-module
-make a directory /var/www/mywebsites/
-throw the ruby app into /var/www/mywebsites/
eg scp -r cce /var/www/mywebsites/
-create a symbolic link to /var/www/mywebsites/cce/public
e.g ln -s  /var/www/mywebsites/cce/public /var/www/cce

-Configure vHosts as follows

<VirtualHost *:80>
  # Normal virtual host info
  ServerName localhost
  #ServerAlias *.seanbehan.com
  DocumentRoot /var/www/
  <Directory /var/www>
         Options FollowSymLinks
        AllowOverride None
        Order deny,allow
        allow from all
        Satisfy all
  </Directory>
  RailsBaseURI /cce
  <Directory /var/www/cce>
        Options Indexes Multiviews FollowSymLinks
        AllowOverride all
        Order allow,deny
        Allow from all
  </Directory>          
  ErrorLog /var/log/apache2/error.log
  LogLevel warn
  CustomLog /var/log/apache2/access.log combined
</VirtualHost>

-------------------------------
We are done. Run http://localhost/cce and the app loads seamlessly.
Have fun!

Simon.
