Though I have successfully installed OpenCDS 5.0 on
Windows XP now, I don't know how to start distributing
content with it now. Let me know if anyone does know
what all do I need to start distributing mobile
content right away.

Finally Successful installation of OpenCDS5.0 on Windows
So finally I did it.
I have installed OpenCds 5.0 on Windows XP.
You can do it as well. Here is how :
1. Download binary for OpenCds 5.0.
2. After unzipping there would be another zip file,
unzip that as well.
3. follow the instructions in doc/5.0/DemoSetupGuide/html/DemoSetupGuide.html.
There are some thing which weren't listed
in the doc or which are listed there but
need to be highlighted. That's what I am
trying to fix here.
0. Remember that you HAVE TO install
Weblogic server on Windows. OpenCDS doesn't
support Sun Application Server on Windows
as of today.
1. Install WebLogic server as described in the doc.
Version 8.1 SP3. For free, you will only get its eval
version, but that is fine. It won't expire and it has
what you need.
2. Install only JDK 1.4. For Jdk 1.5 I got an
invalidclassException, quite late during installation.
3. Install Oracle 10g as described in the doc. If your
PC has DHCP enabled you will have to follow instructions
here.
3.1 When you edit DBConf.xml, Hostname should be set
to your ORACLE_HOST, according to the document
mentioned above, which I find very confusing.
It did not work until I set it to localhost. So the entry
looked like :
4. In the cds_home/cfg/my.cfg file you will have to change
the parameter jndi.url in the same way that you changed
*.internal.uri parameters. Otherwise you will get
java.net.unknownhostexception later in your installation.
5. You will have to change
snmp.manager.address
parameter in deployment/cds/conf/CDSSnmp.properties as well,
otherwise you will get java.net.unknownhostexception later
in your installation.

Visual mode for Gvim on windows
Using Gvim on Windows, for a long time I wasn't able
to figure out why does it happen that I press 'v' in the
escape mode but am not able to select any text visually.
Solution :
:behave xterm
most likely your _vimrc has
behave mswin
replace that with behave xterm,
by going to Edit->Startup settings

something like lsof for windows : openports.exe
Download from :
http://www.diamondcs.com.au/downloads/console/openports.exe
Many a times you want to know which port is being used by which process,
especially when you are installing many a softwares in a single day, all of
which use some port or the other, you might easily get confused.
openports.exe solves it.

Installing OpenCDS on Windows XP
Second Attempt :
Nimish on Momo Delhi suggested that I should try installing it on Linux rather than Windows.
As of now I don't have Linux so I thought I would make it work with Cygwin. As a first
step I installed Oracle 10g from scratch but soon thereafter
I realized that I am making a very basic mistake. I failed to read the following in the
documentation :
6] Currently, only WebLogic Server can be used with OpenCDS on Microsoft Windows platforms.
And I was trying to make it work with Sun Application server.
So now I have 3 options :
1. Get BEA weblogic server and retry for Windows.
There is a catch here, BEA weblogic server is not free and for
free I can download only its eval version. But since I just want
to get a feel of opencds it might be a good option, and also
it seems if I use WebLogic I might get rid of problems that I faced
in my first attempt with regard to broker.sh and deploymq.sh.
2. Try it on Vmware.
3. Try it on Linux.
I will start with 1. as of now.
First Attempt
Note : I haven't been able to install it yet. This is my first and failed attempt.
Note 2 : I don't find enough documentation available for it, so am not sure whether
it's a good idea to use it, since no one else seems to be using it.
I followed the instructions here :
Quick Start Guide.
It asks me to get Oracle 9g, but the documentation that comes
with the binary of opencds (doc\5.0\DemoSetupGuide\html\DemoSetupGuide.html)
asks to get Oracle 10g. And that has much more detailed setup instructions as
well so it's better to follow that.
Anyway, after installing Sun Application server and oracle 9g as mentioned above,
and following rest of the instructions, when I typed
cdsi deploy
it complained :
Files\cds_home"" was unexpected at this time.
The problem was that the path for CDS_HOME included a space, i.e.
C:\Program Files\cds_home
So I simply put it into C:\cds_home, reset CDS_HOME, and the commands worked.
After a few steps I am asked to execute
./deploymq.sh server
but hey, I am on Windows !! And it's a huge sh file, don't know if I would be
able to convert it to .bat.
So I decide to launch cygwin(lucky, that I have it) and run it from there.
There it asked for the license name : pe,try or unl.
I don't know what do these options mean, but it errored out for pe and try,
so I had to settle for unl.
Still, it complained :
imqpassword.txt : No such file or directory.
Now, I have no idea dude, I searched for this file in the Sun Appserver folder and opencds folder
but couldn't find it.
Later, I am asked to run broker.sh, which again is missing everywhere.
So, eventually when I tried cdse startserver, that didn't work either.
Now, here is what I am going to do next :
follow the instructions that came with my copy of opencds, rather
than following the online instructions.
And, rather that using Windows command prompt, I would use cygwin, but I
am pretty sure that wouldn't work either, since I cannot use variables like
/cygdrive/c/etc where I am expected to put C:/etc. So, most likely I won't
be able to install it ever.
but anyway, wish me luck.

Streaming a video file with Flash media server
It's simple.
It works exactly the same way as it does for Red5.
You can test it using JW FLV player.
There are two differences :
1. The folder where you have to place the media file :
For me it is :
C:\Program Files\Adobe\Flash Media Server 3\applications\live
2. RTMP connection URL :
rtmp://localhost/live/
In Red5 it was simply rtmp://localhost/.
For more read this post on how to stream it using Red5.
